Abstract

The utility model discloses a mechanical lock which comprises a lock box, wherein, a triangular tongue, a control tongue and a square tongue are respectively arranged in the lock box, a connecting rod is arranged on the triangular tongue, the connecting rod is in contact with a shifting fork for driving the connecting rod to move downwards, teeth on the shifting fork are meshed with teeth on an interlocking transverse moving part, the control tongue is in contact with the transverse moving part, a square tongue control connecting rod is arranged on the square tongue and connected with a driving gear, the driving gear is meshed with a driven gear and the driven gear is connected with an anti-lock rotating part. When the door is closed, the square tongue of the lock automatically bounces out under the force of a tension spring on the interlocking transverse moving part, and enters the locked state; and when the indoor person needs to leave rapidly, no matter the lock is in the normal closed state or the anti-lock state, the door can be opened under the action of the interlocking transverse moving part when the doorknob is rotated. The utility model has the characteristics of simple structure and convenient operation, thereby being capable of being widely applied to manufacturing the interlocking type mechanical lock.

Description

A kind of mechanical lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of mechanical lock.

Background technology

Mechanical lock on the market all is not provided with the automatic locking door gear usually at present, thereby cause comparatively bothering in the use, in addition, for the mechanical lock of having locked, at first to remove when opening and lock, just can open the door, it is comparatively inconvenient to make when opening the door, so develop the research schedule that a kind of simple in structure, easy to operate linkage type mechanical lock has been put on people.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple in structure, easy to operate linkage type mechanical lock.

The technical scheme that the utility model adopted is:

A kind of mechanical lock, it comprises lock box, be respectively arranged with the triangle tongue in the lock box, control tongue and square tongue, described triangle tongue is provided with connecting rod, connecting rod is connected with extension spring, connecting rod with can drive its shift fork that moves down and contact, shift fork is connected on the cubic iron roll of Door lock handle, the shift fork other end is provided with teeth, teeth go up teeth with traversing of interlock and are meshed, link traversing and be provided with extension spring, described control tongue contacts with traversing, traversing is the inclined-plane with control whip graft synapsis, described traversing and control are provided with torsion spring between the tongue, described side's tongue is provided with and puts the breach of putting traversing top, described side's tongue side of being provided with tongue control link, side's tongue control link is connected with extension spring, side's tongue control link is connected with driving gear, driving gear is meshed with driven gear, driven gear with lock revolving part and be connected, the described revolving part of locking is provided with, following breach, be equipped with the gag lever post that is arranged on the driven gear in the following breach, last breach is equipped with the plush copper of locking goods of furniture for display rather than for use, locks goods of furniture for display rather than for use and is connected with extension spring, locks goods of furniture for display rather than for use and contacts with the tapered end fork.

The beneficial effects of the utility model are: this product is because when closing the door, the square tongue of lock is gone up the ejection automatically down of extension spring active force owing to linking traversing, thereby enters the state of locking a door.When indoor occupant need speed away, no matter lockset is in the state of normally closing the door is still locked state, as long as turn the handle, traversing effect just can be opened door by linking, simple in structure, convenience operation that this product has, thus can be widely used in the making of linkage type mechanical lock.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the state diagram of locking a door of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of mechanical lock, it comprises lock box 1, be respectively arranged with triangle tongue 2 in the lock box 1, control tongue 3 and square tongue 4, described triangle tongue 2 is provided with connecting rod 21, connecting rod 21 is connected with extension spring, connecting rod 21 with can drive its shift fork that moves down 5 and contact, shift fork 5 is connected on the cubic iron roll 51 of Door lock handle, shift fork 5 other ends are provided with teeth 52, teeth 52 with the interlock traversing 6 on teeth be meshed, link and be provided with extension spring for traversing 6, described control tongue 3 contacts with traversing 7, traversing 7 is the inclined-plane with control tongue 3 contact positions, described traversing 7 and control are provided with torsion spring 71 between the tongue 3, described side's tongue 4 is provided with and puts the breach of putting traversing 7 top, described side's tongue 4 side's of being provided with tongue control links 41, side's tongue control link 41 is connected with extension spring, side's tongue control link 41 is connected with driving gear 42, driving gear 42 is meshed with driven gear 43, driven gear 43 with lock revolving part 8 and be connected, the described revolving part 8 of locking is provided with, following breach, be equipped with the gag lever post 44 that is arranged on the driven gear 43 in the following breach, last breach is equipped with the plush copper of locking goods of furniture for display rather than for use 9, lock goods of furniture for display rather than for use 9 and be connected, lock goods of furniture for display rather than for use 9 and contact with tapered end fork 10 with extension spring.

This product is more smooth and easy for control tongue 3 motions that make, and described control tongue 3 bottoms are provided with pulley 31.

When the user presses Door lock handle, Door lock handle drives cubic iron roll 51 rotations, shift fork 5 pushes back triangle tongue 2 in the lock by connecting rod 21, promoting traversing 6 of interlock by teeth 52 in the time of shift fork 5 motions moves, and promoting driven gear 43 clockwise rotates, also rotate synchronously and lock revolving part 8, make the plush copper of locking goods of furniture for display rather than for use 9 be in the last breach of locking revolving part 8, this moment, driven gear 43 moved by driving gear 42 drive side's tongue control links 41, and square tongue control link 41 is return square tongue 4 in the lock.

When lock needs to lock after sealed, rotate and lock revolving part 8, make the plush copper of locking goods of furniture for display rather than for use 9 break away from and lock the last breach restriction of revolving part 8, and the other end of locking goods of furniture for display rather than for use 9 moves down the rotation of obstruct tapered end fork 10, thereby play antitheft effect.

This product is because when closing the door, the square tongue 4 of lock since in traversing 6 of the interlock extension spring active force eject automatically down, thereby enter the state of locking a door.When indoor occupant need speed away, no matter lockset is in the state of normally closing the door is still locked state, as long as turn the handle, just door can be opened by the effect that links traversing 6, simple in structure, convenience operation that this product has, thus can be widely used in the making of linkage type mechanical lock.
