Description

 Mechanical linkage lock cylinder opened with a thin key card

[Technical Field]

 The present invention relates to a keyed lock cylinder suitable for use in various locks, and more particularly to a mechanical interlocking lock cylinder that is opened by a thin key card. It has a wide range of applications, and can be applied to hotel door locks. It can also be used for home and anti-theft requirements. It can also be used for locks, padlocks, cabinet locks and other common locks.

 【Background technique】

 At present, the use of keys to open the lock of the lock cylinder has become an indispensable security product in daily life and work. There are many types of locks available, but in terms of various factors, mechanical locks are still widely used. The actual use certificate, usually the mechanical lock formed by the lock body and the lock cylinder opened by the key to realize the movement of the lock tongue on the lock body, generally has the following defects:

 The keyhole for inserting a key on a conventional lock cylinder is large, and the unlocking tool for abnormal use can be easily inserted into the keyhole for technical opening, so that the lock cylinder drives the paddle to realize the movement of the lock tongue, and the lock is easily stolen. For the key to provide the corresponding torque for the rotation of the lock cylinder, it is necessary to have a certain strength and to meet the requirements of the key wear resistance, and generally use precious and toxic metal materials such as silver, copper, lead, etc. as the special raw materials for manufacturing the key. This increases both manufacturing costs and environmental pollution. Limited by the lock core structure, the existing key is bulky and complex in shape, making it difficult to carry and store.

 The second improved card-type lock still has the following problems: The card-type key used is convenient to carry, but the key piece is still too thick, bulky, and cannot be bent into the keyhole, so it cannot prevent abnormal use. The unlocking tool is inserted and the technology is turned on. The lock is a one-piece structure, regardless of the lock cylinder and the lock body. The lock cylinder cannot be used on the lock body of other locks. The password hole on the individual thin key card is not reasonable in designing the control structure of the marble. When the lock is unlocked, the difference in the marble level is too small. The error in production and processing is far greater than the level difference of the marble in the technical solution, so it cannot be actually produced and used. The existing thin key card has no protective measures, and the key card is easily damaged by the marble when the lock is unlocked. Therefore, the thin key card of the existing card lock is difficult to practically apply. These problems can be seen in the following examples.

For example, the "mechanical card lock" of Chinese Patent No. 92113343.X discloses a mechanical lock using a card. The lock is improved on the basis of the structures of the French patents 4149394, 4338805, 4627252, 4587815, 2692495, and the French patent 1163526. The structure overcomes the defects of some cards being latched, and is inserted by a hard key card having a certain thickness. In the lock, the cam mechanism is driven by turning the handle to unlock. The main advantage of the lock is that it is easy to change the key card with a code card, especially for hotel locks. The disadvantages of the lock are: 1 key card is too thick and bulky, the key card material is too much and not easy to carry; 2 the key card hole is straight, the width is large, the abnormal use of the unlocking tool is easy to insert The technology is opened; 3 the shrapnel in the lock is used to control the depth of the hole inserted into the keyhole. Although this can make the shrapnel very poor, but the structure is complicated, the shrapnel is easy to get stuck; 4 the inner shrapnel of the lock is in the form of a sheet, Parallel to each other, because the shrapnel can not be rotated to reduce the number of teeth generated by the rotation, the amount of the key is limited; 5 The lock cylinder is of a unitary structure, regardless of the lock cylinder and the lock body, is a special type lock, and is now widely used lock The body is not universal, it can only be applied to the door lock of the hotel. It is not suitable for the family and the anti-theft requirements. It can not be used for common locks such as car locks, padlocks, cabinet locks, etc. 6 The lock core structure can only be moved in parallel and unlocked. The rotation is unlocked, and the rotating structure can be widely used in other locks, so the application range is small.

 Chinese Patent No. 200410058020.0 discloses a "mechanical lock for key-type double-column card high security door", which uses a thin key card, but also has the following problems: 1 key card area is large; 2 key card can not be bent and inserted 3 The main feature of the structure is the double-column structure. This structure is integral, regardless of the lock core and the lock body. The lock cylinder is large in volume, and the existing lock body is not universal and has a single purpose. 4 The top of the identification column is a cylinder. Shape, not designed into a sheet shape, and the top end adopts the sheet form to increase the key volume and reduce the key card area; 5 The lock uses the relative movement of the "hole plate" and the "pillar" to complete the unlocking, and cannot realize the rotation unlocking The lock is specific and the application area is limited.

 The patented No. 98234973.4 "Thin-type key for mechanical locking with a PIN" uses a thinner key card. The solution only describes the improvement of the key, and does not consider other parts of the lock cylinder. There are problems in the following cases: 1 The top of the identification marble is a separate ball or roller. The depth (step difference) of the key hole of the ball or roller entering the key card is not linear. When the circumference of the ball is close to the circumference of the ball, the difference is too small. Therefore, the number of distance segments in which the marble moves in the structure is small, and the amount of the key is made very low. 2 The key card must be integrated with the rotating handle. This is the main feature of the technical solution. The key structure is complicated and it is not convenient to carry. 3 The structure does not consider the protection of the thin key card. The practical application of the key card is easy to be The top of the marble is bad; 4 The top of the marble can only be spherical or wheel-shaped, otherwise the key card can not be inserted, and the spherical and wheel-shaped structure is not as high as the key-shaped structure with the change of the card hole angle.

 In summary, some defects in the existing mechanical card latching affect its popularization and application, and therefore need to be further improved. [Summary of the Invention]

 The object of the present invention is to provide a mechanical interlocking lock cylinder opened by a thin key card, which has a reasonable structural design, and other shackle tools cannot be inserted into the thin keyhole, thereby overcoming the existing locks and being easily stolen, and the keys are easily damaged. It has the advantages of large volume of key cylinder, easy processing, safe use, good versatility and wide application range. The thin key card used is well protected, not easy to damage, small in size, easy to transport, easy to carry and keep. Therefore, the anti-theft performance and the service life of the lock can be significantly improved.

The object of the present invention is achieved as follows: The lock cylinder comprises a clutch rotating body, a core sleeve body and an outer marble assembled therein, an inner marble and a thin key card provided with a through-hole identification hole, the technical points of which are: the core sleeve The body assembly has an outer marble slider controlled by the limit slide body and an inner marble slider and a cover, and one end of the inner marble slider is engaged with the protective plug at one end of the linkage knob The slide rail or the chute is arranged on the limit slide body so that each slider slides along the axial direction of the core sleeve body or rotates along the circumference of the core sleeve body, and the outer marble guide body and the key card support for holding the thin key card The body and the reset magazine are assembled between the outer marble sealing plate fixed on the core sleeve body and the clutch rotating body or the cover, and a socket for inserting the thin key card is formed between the outer marble guiding body and the key card supporting body, and The corresponding outer wall of the core sleeve, the outer wall of the cover or the notch of the core sleeve body and the edge of the cover have a through hole of a thin key card, and the outer marble and the inner marble use a tension spring and an outer marble The sealing plates are respectively arranged in the marble holes of the outer marble slider and the inner marble slider, and the outer end of the outer marble bullet column is provided with a cone or a snap-shaped warhead and a limit stop stuck to the outer marble sealing plate, and the outer marble bullet The column and the column of the inner marble are the same as a cylinder or a prism, and the outer marble sealing plate, the outer marble guiding body and the key card supporting body are respectively provided with marble through holes corresponding to the marble identification holes on the thin key card, and the holes Shape, size, arrangement direction, arrangement position and outer marbles Conical or bullet shaped wedge, size, arrangement direction, arranged in the same position.

 The bottom surface of the outer bullet column is a right angle section, and the top surface of the inner marble slider is a right angle section, and the top surface of the inner bullet column and the bottom surface of the outer marble slider are respectively chamfered or rounded.

 The cross-section of the cone or the chevron of the outer bullet bullet is in the form of a regular square, elliptical, truncated or irregular curve.

 One end of the inner marble slider is engaged with a protective plug or a clutch rotating body at one end of the linkage knob, and the other end of the inner marble slider passes through the center of the outer marble slider, the outer marble guide body, the thin key card and the key card support body. One end of the clutch's clutch link is engaged, and the other end of the clutch link is engaged with the clutch swivel or the linkage knob.

 The distance between the outer flange of the cone or the bottom of the outer bullet is greater than the diameter of the outer bullet or the distance between the edges of the prism.

 The marble identification hole of the thin key card and the outer marble guide body, the key card support body and the marble hole on the outer marble cover plate of the corresponding thin key card are circumferentially distributed or arranged in a straight line or a curved line. Distribution in the direction of the line.

 The outer marble adopts a split structure, and includes a shoulder with a bullet and a stop and a column with an adjustable length.

 The protective plug at one end of the linkage knob is engaged with one end of the inner marble slider, and the inner marble slider fixed the clutch rotating body.

 The outer marble guide body is formed by combining a plurality of single hole marble bodies.

 The outer marble and the inner marble respectively adopt a mother-child structure, and the outer marble includes a hollow female outer marble and an outer marble which is set in the hollow female outer marble, and the inner marble is included in the hollow female inner marble and is set in the hollow female inner marble. Inside the marble.

Since the invention uses the linkage knob and the thin key card with the bullet identification hole and the action of controlling the inner and outer marbles and the clutch link, the clutch rotation action can complete the opening of the lock core, so the structural design is reasonable. Can significantly improve the anti-theft performance of the lock and extend the service life. The reason is: the outer marble guide and the key card for holding the thin key card The thin key card socket between the support body is disposed between the outer wall of the core sleeve, the outer wall of the cover or the notch of the core sleeve body and the edge of the cover, and the thickness of the thin key card is thin (can be 0.1~0.5) In mm), the key socket for the thin key card insertion is very narrow, and other unlocking tools with strength cannot be inserted; the weight of the key card material is one-tenth of the weight of the existing key, and the cheap and environmentally friendly material such as elastic steel sheet is used. Made of metal material that is not expensive or toxic (lead-containing), the thin-key card is not easily damaged. It is smaller than the existing key, saves material, is easy to process, and is easy to carry and store. Therefore, the existing locks are easily overcome, and the keys are easily damaged, and the belts are not damaged. The reason why the linkage knob can make the inner and outer marble sliders slide or circumferentially rotate along the axial direction of the core sleeve body, or directly act on the clutch rotation body to generate torque between the inner and outer marble sliders and the clutch rotating body, mainly due to the torque. The limit slide body is provided with a sliding table or a sliding groove for sliding the respective sliders in the axial direction of the core sleeve body or in the circumferential direction of the core sleeve body. The limit slide or chute can control various components including the thin key card in the core groove, and the linkage knob can generate the inner marble slider and the outer marble slider only when it completely reaches the defined position. Relative movement. Therefore, the limit slide body on the core sleeve functions to protect the thin key card from damage. At the same time, a contoured enlarged structure formed by a tapered or tapered shaped warhead provided at the outer end of the outer bullet column and a bottom outer flange of the tapered body or the tapered body and a limit stop stuck to the outer marble sealing plate, The key amount of the lock cylinder can be significantly increased and the use can be safer. In addition, the universal structure of the lock cylinder used can also be matched with the lock body of various structural locks, and the scope of application is wider.

 The lock cylinder can also be optimally combined on the structure of the inner and outer marbles and their sliders, and the design of the thin key card. The protection mechanism of the thin key card is designed to prevent the thin key card from being damaged by the marble to ensure the damage. The protection of the thin key card is more appropriate, so that the lock cylinder with the thin key card can be better applied to various locks.

 【detailed description】

 The specific structure of the present invention will be described in detail based on Figs. The lock cylinder comprises a linkage knob 1 with a protective plug 2, a core sleeve body 3, a limit slide body 4 assembled thereon, a cover fixing body 5, a cover 10, and an inner marble assembled in the core sleeve body 3. Slider 18, outer marble slider 17, tension spring 16, inner marble 15, outer marble 14 with outer bullet 24 and outer marble stop 21, clutch link 13, outer marble seal 6, return spring 12. The outer marble guide body 7, the key card support body 8, the clutch swivel 9, and the thin key card 11 and the like which are provided to pass through the pin identification hole 28. The specification and shape of the core sleeve 3 should be determined according to the components assembled in the assembly and the actual use requirements. It is mainly used for the combination of the lock cylinder and other common locks of various structures, such as the lock, padlock and cabinet shown in FIG. The lock body such as the lock is matched and combined.

 The inner marble slider 18 and the outer marble slider 17 assembled in the core sleeve body 3 are controlled by the slides or chutes of appropriate lengths disposed on the limit slide body 4 to be respectively disposed along the core sleeve body 3 The shaft slides or rotates in the circumferential direction of the core body 3. The outer marble 14 and the inner marble 15 are respectively arranged in the marble holes of the outer marble slider 17 and the inner marble slider 18 by the tension spring 16 and the outer marble sealing plate 6. The outer end of the outer marble 14 (i.e., toward the end of the outer marble guide 7) is provided with a cone 20 of a tapered body or a chevron and a limit stop 21 which is engaged with the outer marble sealing plate 6. The cross-section of the cone or the chevron of the outer bullet bullet 20 may be a regular square, elliptical or truncated circle, or an irregular curved shape, which is completely different from the warhead structure of the conventional marble. The limit stop 21 can completely pass the bullet 20 of the outer marble through the bullet through hole of the outer marble sealing plate 6, and can ensure that the outer marble 14 is restrained by the outer marble sealing plate 6 from the outer marble slider 17.

 In order to keep the step of the marble identification hole 28 on the thin-key card 11 sufficiently large, the distance between the outer flange of the outer bullet or the bottom outer flange of the clip should be larger than the diameter of the outer bullet or the edge of the prism. The distance between the outer marbles 14 formed by this is a greatly enlarged structure.

For ease of processing, the outer marble 14 can also employ a split structure, which includes a shoulder with a bullet 20 and a stop 21. 22 and a column 23 of adjustable length. The shoulder and the warhead 20 and the stop 21 thereon can be made into a standard-sized universal part according to the shape of the bullet, and the column 23 can be made into a long and short cylindrical body so as to be properly matched with the shoulder 22 into various specifications. The outer marbles 14 come. The column of the outer marble 14 and the column of the inner marble 15 are cylindrical or prismatic.

 In order to increase the size and shape of the outer marble 14 and the inner marble 15, the outer marble 14 and the inner marble 15 can be separately processed into corresponding sub-structures. The sub-balls include hollow female outer marbles 25 and outer marbles 24 that are nested in hollow female outer marbles. The inner female marbles include hollow female inner marbles 27 and inner inner marbles 26 that are nested in hollow female inner marbles.

 The bottom of the marble hole of the inner marble slider 18 may be a blind hole or a cover, and the outer marble sealing plate 6 prevents the outer marble 14 from being completely ejected by the tension spring 16 to the outer marble slider 17. The outer marble seal 6 and the outer marble slider 17 can also be formed in one body. The function of the return spring 12 is to automatically return the initial position after the outer marble slider 17 is axially moved. An end surface of the inner marble 15 is in contact with the bottom surface of the outer marble 14 corresponding to the outer marble slider 17 before the lock is opened. When the lock cylinder and the lock body in the existing lock are to be relatively slid, although the outer marble should not enter the lock cylinder at this time, the bottom end of the outer marble has a chamfer (generally, the lock marble must have a chamfer greater than 0.2 mm). Coupled with factors such as machining errors, the external marbles will be forced into the lock cylinder by the lock body. In this way, the top of the outer marble will damage the thin key card. The chamfering of the top of the lock body also causes the consequences of such a bad top card. In order to prevent the thin key card 11 from being damaged, and at the same time, the bottom of the outer pin 14 can be processed into a right angle section, and the top surface of the inner marble slider 18 is processed into a right angle section, and the inner marble is processed. 15 The top surface of the column and the bottom surface of the outer marble slider 17 are respectively chamfered or rounded, so that the top bad key card existing in the prior art can be fundamentally solved. As shown in Fig. 5(c), the bottom edge of the outer marble 14 is kept sharp and angular, and the edge of the marble hole of the inner marble slider 18 is kept sharp and angular. On the contrary, the edge of the inner marble 15 and the edge of the outer marble slider 17 must be chamfered. Only in this way can the thin key card anti-top structure be formed, and when the outer marble should not enter the outer marble slider, the outer marble 14 cannot be forced into the outer marble slider by the inner marble slider 18.

The shield plug 2 at one end of the interlocking knob 1 placed outside the core casing 3 is engaged with one end of the inner marble slider 18 for pushing, pulling or rotating the inner marble slider 18 or the outer marble slider 17. The outer marble guide body 7 and the key card support body 8 and the return spring 12 that hold the thin key card 11 are assembled between the outer marble cover plate 6 fixed to the core sleeve body 3 and the clutch rotating body 9 or the cover 10. During assembly, a socket for inserting the thin key card 11 is formed between the outer marble guide body 7 and the key card support body 8, the outer wall of the core sleeve body 3 corresponding to the socket, the outer wall of the cover 10 or the groove of the core sleeve body 3. Between the mouth and the edge of the cover 10 there is a socket for the thin key card to facilitate insertion of the thin key card 11. The outer marble sealing plate 6, the outer marble guiding body 7 and the key card supporting body 8 are respectively provided with marble through holes corresponding to the marble identifying holes 28 on the thin key card 11, the shape, size, arrangement direction of each hole, The arrangement position is the same as the shape, size, arrangement direction, and arrangement position of the bullet 20 of the tapered or wedge-shaped body of the outer marble 14. The outer marble guide body 7 is convenient for combining different angles and different shapes of the marble holes, and can be assembled by a plurality of single-hole marble bodies of different shapes according to the requirements of the required angle or shape. One end of the inner marble slider 18 can be engaged with the protective plug 2 or the clutch rotating body 9 at one end of the interlocking knob 1, and the other end of the inner marble slider 18 passes through the outer marble slider 17, the outer marble guiding body 7, and the thin spoon. The card 11 is engaged with the clutch pin 13 end of the center hole of the key card support body 8, and the other end of the clutch link 13 is engaged with the clutch rotating body 9 or the interlocking knob 1. After one end of the inner marble slider 18 is further engaged with the protective plug at one end of the linkage knob 1, the inner marble slider 18 is fixed to the outer circumference of the toothed clutch. In order to prevent the abnormal unlocking person from removing the interlocking knob 1 and destroying the lock cylinder with the electric drill, a hard alloy steel anti-drilling piece is disposed between the core sleeve body 3 and the inner marble slider 18 or between the cover 10 and the key card support body 8.

 The marble identification hole 28 of the thin key card 11 and the outer marble guide body 7, the key card support body 8 and the outer marble cover plate 6 of the corresponding thin key card are arranged in a circumferential direction or in a straight line. Or the line direction of the curve arrangement. For easy carrying and storage, the thin key card 11 is provided with a plug body 29 at one end, or a plug body 29 may be provided at one end, and a direction identification mark 30 may be provided at the other end. The direction recognition mark 30 may be formed with a projection or a notch at the edge portion of the thin key card 11, or may be printed or engraved on the surface of the thin key card 11. Its setting is mainly for the thin key card 11 to be inserted in the correct direction at the socket or to increase the visual effect of the thin key card 11 in the correct insertion direction, so as to correctly insert the thin key card 11 for unlocking. Namely, it is possible to clearly judge by the direction identification mark 30 whether or not the insertion direction of the thin key card 11 is correct.

 The invention is further described below in conjunction with the embodiments. However, the content does not constitute a limitation of the scope of the present invention.

 Embodiment 1 In combination with FIG. 1 and FIG. 5, the mechanical key card linkage lock cylinder is composed of: linkage knob 1, core sleeve body 3, limit slide body 4, cover fixing body 5, outer marble seal plate 6, outer marble guide Body 7, key card support 8, clutch swivel 9, cover 10, thin key card 11, return spring 12, clutch link 13, outer marble 14, inner marble 15, tension spring 16, outer marble slider 17 The inner marble slider 18, the connecting screw 19, and the like, and the thin key card 11 is a key for opening the lock.

The specific operation process is as follows. Fig. 5a and Fig. 5b show the state before the lock cylinder is opened (the thin key card 11 has been inserted) and the state after the opening. First, the thin key card 11 is inserted into the key card socket. Since the thin key card 11 has an asymmetric protrusion, if the direction is not correct, the thin key card 11 will not be inserted. After the thin key card 11 is in place, the linkage knob 1 is pushed to the limit. Comparing FIG. 5a to FIG. 5b, it can be seen that the linkage knob 1 and the outer marble slider 17 together with the inner outer marble 14, the inner marble 15 and the like move the outer marble guide body. 7. The outer marble slider 17 abuts on the marble sealing plate 6, and the top ends of the outer marbles 14 respectively enter the corresponding marble identification holes 28 on the thin key card 11. The size of the marble identification aperture 28 defines the depth at which the top end of the outer marble 14 enters the marble identification aperture 28. At the same time, the clutch link 13 is engaged with the clutch link through hole 31 on the thin key card 11 and the clutch rotating body 9. If the thin key card 11 of the lock core is used at this time, the depth of each outer marble 14 entering the marble identification hole 28 is such that the interface between the outer marble 14 and the inner marble 15 and the outer marble slider 17 and the inner marble slide The interface of the block 18 is on the same surface. At this time, the twisting linkage knob 1 can drive the inner marble slider 18 to rotate, and at the same time, the clutch linkage 13 and the clutch rotating body 9 are rotated, and the clutch rotating body 9 can drive the lock. Mechanisms (such as lock tongues) act. Did not reach a cycle during the twisting When the position or the position is set, the inner marble slider 18 is retracted due to the limitation of the slide or the chute on the limit slide body 4. Up to one week or set position, by the action of the return spring 12 and each tension spring 16, the moved parts can be pushed back to the initial position, at which time the clutch link 13 and the clutch swivel 9 are also separated, the thin key card 11 can be pulled out. During the pushing of the linkage knob 1, the linkage knob 1 cannot be twisted due to the limitation of the limit slider body 4, in order to protect the thin-key card 11 from being damaged by the outer marble 14.

 After the linkage knob 1 is pushed into position, if the illegal key card is used, since the interface between the outer marble 14 and the inner marble 15 of each group and the outer marble slider 17 and the inner marble slider 18 are not all on one surface, Due to the limitation of the inner and outer marbles, the outer marble slider 17 and the inner marble slider 18 cannot slide relative to each other, and the lock cannot be opened. At this time, if the linkage knob 1 is forcibly twisted, the thinner part of the linkage knob 1 or the protective plug will be broken, which is equivalent to the fact that the key of the traditional lock is twisted, and the lock will not be smashed.

 The lock cylinder of the embodiment can be used in combination with various locks. When combined with the outer lock, a connection fixing device can be disposed outside the core sleeve 3 as needed. In the embodiment, the initial part of the key card socket is installed on the outer lock, and the thin key card 11 is determined by the initial stage of the key card socket, and is inserted into the key card socket. It can be seen in Fig. 1 that the key card socket of the present embodiment is formed by inlaying and splicing the core sleeve body 3 and the cover 10 through the fixed connecting member 19.

 Embodiment 2 is shown in Figure 6. The operation procedure is the same as that of the first embodiment. Structurally different, the interlocking knob 1 of the present embodiment is placed on the side of the key supporting body 8 side. The structure cover 10 slides together with the interlocking knob 1, but does not rotate therewith, and the rotational power passes through the clutch rotating body 9. Another clutch swivel that drives the outer lock is designed to be integral with the inner marble slider 18. The structure is additionally provided with a cover, and the pin is fixed to one end of the inner pinion. The structure key card socket is located on the cover 10.

 Embodiment 3 is shown in Figure 7. This design is also characterized by the linkage knob 1 on one side of the key support body 8. Another feature of this embodiment is that the clutch link does not pass through the thin key card 11 but is deformed into a groove in which the clutch slide 32 is inserted into both sides of the outer marble slider 14, and the other end of the clutch slide 32 is coupled with the cover 10 as One. This structure is simpler but the thin key card 11 is rotated together with the interlocking knob 1, and the structure is such that the outer marble slider 17 rotates with the interlocking knob 1 instead of the inner marble slider 18 in the front embodiment. The clutch swivel and the outer pin slider 17 are integrated. The operation of unlocking is the same as that of the first embodiment.

 Embodiment 4

As shown in Fig. 8, this is an example in which a thin key card 11 is inserted from the front side, and the marbles are arranged in a line direction. The limit slide body 4 of the structure is designed to have a groove in the cylinder, and the outer marble slider 18 is mounted in the groove. In addition, an important feature of the embodiment is that when the linkage knob 1 is pushed, the direction in which the inner marble slider 18 moves is perpendicular to the pushing direction, and the interface between the inner marble slider 18 and the outer marble slider 17 is cylindrical.
