Description
The utility model relates to a kind of new-type button door lock, belongs to international Patent classificating number E05B lock
At present, no matter the various door locks of domestic use are single tongue, two tongue or three tongues, all because of the horizontal symmetrical line parallel of its locking bolt direction of motion and lock, thereby after on the door lock, can directly touch locking bolt by crack between a door and its frame with instrument lock is opened, so the theftproof performance of lock is not high.Ground such as external West Germany, the U.S., Canada, Japan and Hong Kong have designed and manufactured the locking bolt direction of motion button door lock vertical with the horizontal symmetry-line of lock at this shortcoming.Like this, after on the door lock, locking bolt interlaces with crack between a door and its frame and is parallel, can't touch locking bolt from crack between a door and its frame with instrument, thereby has improved the theftproof performance of lock, and the button door lock that produces as Japan just belongs to this a kind of door lock.Thisly be latched in following three shortcomings:
1. part processing and assembly technology difficulty are big, be unsuitable for production in enormous quantities, reason is as follows: and (referring to Fig. 9. Figure 10, Fig. 1 .) this lock is opened and the conversion of locking two positions has two approach, the one, drive the interior pin 27 of dialling by transposition hand button 25 and back down middle transposition pin 42, discharge lock bolt plate 11, drive by interior group of pin 27 again and go up transposition pin 41 or transposition pin 43 motions down, and upward transposition pin 41 all is the protruding pin that turns down from lock bolt plate 11 with the pin 43 that replaces down, thereby lock bolt plate 11 is along with moving up and down, locking bolt 10 is an one again with lock bolt plate 11, so finish the locking of lock or open conversion.The second approach is by key 30 rotational lock cores 31, lock core link rod 32, drives outer dial sleeve 34, outer plectrum 35 on the cover plate 33 again, backs down middle transposition pin 42 on the pendulum-type location-plate 46 again by outer moving tooth 36, and below action is with above-mentioned article one approach.Thus mechanism principle as can be known, on replace pin 41 and down the work plane of transposition pin 43 must be positioned on the same arc surface, simultaneously, middle transposition pin 42 work planes must be on the string of this circular arc.The assembly technology of the processing technology of parts such as lock bolt plate 11, pendulum-type location-plate 46, interior plectrum 26, outer plectrum 35 and these parts certainly will require very highly like this, causes very big difficulty in production in enormous quantities.
2. this lock does not have striker mechanism, and the people must use extremely inconvenient by key 30 when locking a door outdoors like this.
3. this lock does not have internal lock to protect mechanism and external lock Nei Bao mechanism outward, promptly can't realize in the door with transposition hand button 25 can't opening the door with key outdoors after on the door lock; Outdoors with key with after on the door lock, can't open the door with the hand button 25 that replaces in the door.Therefore theftproof performance is high not enough.
Task of the present utility model just provides a kind of novel button door lock that overcomes above-mentioned shortcoming, reaches processing, assembling is simple, easy to use, theftproof performance is high purpose.
This task is to realize with following technical scheme: at the snap close 1 that adopts Japanese padlock, on the basis of lock body 4 locking bolts 10 and cover plate 33, inversion mechanism has been carried out improving design, increased striker mechanism simultaneously.
Inversion mechanism: be to make lock realize locking, the mechanism of opening two evolutions.Become the transposition of enable possition by locked position of coupler, can be respectively by interior inversion mechanism and the realization of outer inversion mechanism; Becoming locked position of coupler by the enable possition is finished by striker mechanism.
Interior inversion mechanism (referring to Fig. 1, Fig. 2) comprise transposition hand button 25 of the prior art, interior plectrum 26, lock bolt plate 11, improved part is:
1. interior plectrum 26: at first interior group of pin 27 above it changes into interior plectrum 26 plane parallel or on same plane, simplified processing technology; It two is provided with a reclinate return spring tooth 28 on interior plectrum 26; Its three be below interior plectrum 26, be equipped with one the compression spring be called hand button return spring 29, this spring is contained in the arc groove proficiency button return spring groove 5 of fan-shaped boss in the lock body 4, arc groove is consistent with the rotational trajectory of return spring tooth 28, when the people rotates transposition hand button 25, just plectrum 26 in can driving, return spring tooth 28 will compress hand button return spring 24.
2. lock bolt plate 11: the transposition pin changes a tooth that bends vertically upward with lock bolt plate 11 planes into and is called locking bolt transposition pin 14, has simplified manufacturing process.When interior group of pin 27 along with interior plectrum 26 to lock opening direction when rotation, just with locking bolt pin 14 vertical phase-changes that replace.
Outer inversion mechanism (referring to Fig. 1. Fig. 3) comprise key 30 of the prior art, lock core 31, lock core link rod 32, outer dial sleeve 34, outer plectrum 35.Improved part is: the outer moving tooth 36 on the outer plectrum 35 change into outer plectrum 35 at conplane tooth, simplified processing technology.Outside plectrum 35 below the transposition safeguard 37 that can be promoted rotation of having gone back kink by outer moving tooth 36, center of rotation still is the center of rotation of outer plectrum 35.On transposition safeguard 37, have and dial pin 38 outside one.So, when the people when being rotated counterclockwise key 30 outdoors, drive lock core 31 successively, lock core link rod 32, the outer dial sleeve 34 on the cover plate 33, outer plectrum 35, outer moving tooth 36 is stirred transposition safeguard 37 the outer group of pin 38 on it is rotated, the locking bolt transposition pin 14 on the last shooting the lock-bolt plate 11, thereby the locking bolt 10 that joins together with lock bolt plate 11 is moved upward, finish the transposition task that latches to unlatching.
Striker mechanism is to finish lock by the specialized agency of enable possition to the locked position of coupler transposition.(referring to Fig. 4. Fig. 5 .) this mechanism is made up of pendulum-type latch bar 19, latch pole spring 22, latch lever pin 23 and latch return spring 24.Pendulum-type latch bar 19 is hinged on the inboard of lock body 4 lower walls by latch lever pin 23, its free end has the groove in the following locking bolt chamber 9 of a latch pin 20 from lock body 4 and stretches out, its latch position-limit foot in middle part 21 just with lock bolt plate 11 on locking bolt position-limit foot 13 withstand, being equipped with one below the latch position-limit foot 21, to compress spring be latch pole spring 22.In addition, it is latch return spring 24 that a torsion spring also is housed on the inner chamber projection of lock body 4, and the one end colludes on lock bolt plate 11, and the other end is supported on lock body 4 inside sidewalls.When door is being opened and lock be in the enable possition, a very important person is conveniently with Men Yiguan, then latch pin 20 is depressed by ring lock button 1, pendulum-type latch bar 19 and the latch position-limit foot 21 on it are around 23 rotations of latch lever pin.When latch position-limit foot 21 is thrown off the locking bolt position-limit foot 13 that withstands owing to rotation dips, because the torsion of latch return spring 24 makes lock bolt plate 11 move to latch position-limit foot 21 along guide rail 6 by gathering sill 16 on one side, thereby locking bolt 10 is moved down, from last locking bolt chamber 7, stretch out in the locking bolt chamber 8, from the circular buttonhole of snap close, pass annular snap close 2 is locked together, finish lock by the conversion of opening to locked position of coupler.When next time by locking when replace in the enable possition because lock bolt plate 11 moves up, no longer oppress latch position-limit foot 21, under the elastic force of latch pole spring 22, pendulum-type latch bar 19 is resetted.
In order to realize the outer requirement of protecting of internal lock, this lock has also been set up an internal lock and has been protected mechanism outward.(referring to Fig. 6) this mechanism is by location hand button 17, and the locking bolt positioning tooth 12 on location-plate 18 and the lock bolt plate 11 is formed.Location hand button 17 is positioned at the bottom outside of lock body 4, and location-plate 18 is positioned at the bottom inside of lock body 4, and is installed on the mandrel of location hand button 17.Location hand button 17 has two positions: safety position or normal position.In addition, locking bolt positioning tooth 12 is like this designs: it is a tooth of bending downward vertically, and when lock bolt plate 11 is in locked position of coupler, if 17 groups on location hand button to safety position, lucky and location-plate 18 bottoms of locking bolt positioning tooth 12 inner working faces are withstood; When lock bolt plate 11 is in the enable possition, if 17 groups on location hand button to safety position, withstand lucky and location-plate 18 tops of locking bolt positioning tooth 12 outer work planes.So, after on the door lock, if the people in door 17 groups on location hand button to safety position, then the people can't open door with key outdoors, promptly reaches the outer purpose of protecting of internal lock.
In addition, when lock bolt plate 11 is in the enable possition (referring to Fig. 8), if 17 groups on location hand button to safety position, then striker mechanism can't make lock realize transposition to locked position of coupler, thereby makes striker mechanism ineffective, lock is in full-gear.So when the people is in,, made things convenient for the user because frequent discrepancy can not make on the door lock.
In order to protect function in the external lock of realizing locking, this lock also has an external lock Nei Bao mechanism.(referring to Fig. 7/Fig. 3) this mechanism is made up of the transposition insurance tooth 15 on insurance tooth 39 on the transposition safeguard 37 and the locking bolt transposition pin 14.The relation of the two designs like this: when locking with key 30 when replacing to blocking, the groove on the insurance tooth 39 catches on transposition insurance tooth 15 just, makes lock bolt plate 11 be in locked safety position.At this moment the people can't make lock be changed to the enable possition at door inward turning conversion position hand button 25, thereby has reached the requirement of protecting in the external lock.
All possess above-mentioned inversion mechanism, striker mechanism, internal lock and protect the button door lock of mechanism and external lock Nei Bao mechanism outward, be most preferred embodiment of the present utility model.Such lock theftproof performance height; Use very convenient; Because part processing is easy, matching requirements are not high, thereby make cheap, only suitable with Japanese padlock.
