Abstract

The utility model relates to a lock tongue assembly for an anti-prying lock. A lock tongue is connected with a lock tongue drag plate which is provided with shifting teeth matched with a lock core shifting block. The lock tongue is a lock hook which is connected with the lock tongue drag plate through a rotating shaft. The lock hook which can rotate around the rotating shaft is provided with a return spring. One end of the return spring is connected with a hook of the lock tongue drag plate, and the other end of the return spring is connected with a hook of the lock hook. As the lock hook is provided with a return spring, when the lock is unlocked, the inner end of the lock hook departs from a lock panel, the return spring presses the lock hook to rotate around the rotating shaft, and the lock hook can retreat from a door frame and the lock panel easily. Therefore, the reliable work of the lock is guaranteed.

Description

Pick-proof lock dead bolt assembly

Technical field:

The utility model relates to lock technology field, particularly a kind of pick-proof lock dead bolt assembly.

Background technology:

At present, various pick-proof lock structures are numerous.As Chinese patent a kind of " pick-proof lock " just proposed for No. 03279359.6.In this technical scheme, it is flexible that lock core drives dead bolt by moving part, is connected with the guide pillar and the dead bolt that are used to promote multidirectional locking bar on the bolt plate.Be provided with latch hook in the dead bolt, latch hook can rotate around its rotating shaft, and the latch hook rotating shaft is installed in the dead bolt.Dead bolt is when lock-out state, and latch hook locks doorframe and panel of lock together, and it can improve the pick-proof performance of pick-proof lock.But have the following disadvantages:

1, because the latch hook of above-mentioned pick-proof lock does not have automatic reset mechanism, make dead bolt when retraction, latch hook is stuck on the doorframe easily, causes lockset work unreliable.

2, the latch hook of above-mentioned pick-proof lock is installed in the dead bolt, makes the lock structure complexity, the manufacturing cost height.

Summary of the invention:

The purpose of this utility model is: a kind of pick-proof lock dead bolt assembly simple in structure, reliable operation is provided.

The utility model is achieved through the following technical solutions:

A kind of pick-proof lock dead bolt assembly, be connected with dead bolt on the dead bolt planker, the dead bolt planker is provided with the moving tooth that matches with the lock core shifting block, it is characterized in that: described dead bolt is a latch hook, be connected by rotating shaft between latch hook and dead bolt planker, latch hook can rotate around the axis, and latch hook is provided with back-moving spring, back-moving spring one end is connected on the hook of dead bolt planker, and back-moving spring one end is connected on the hook of latch hook.

Advantage of the present utility model is: because pick-proof lock is with being provided with latch hook in the dead bolt assembly, lockset is when lock-out state, and panel of lock is oppressed latch hook the inner, and latch hook overcomes the elastic force of back-moving spring, doorframe and panel of lock are locked together, make lockset that good pick-proof performance be arranged.Because latch hook is provided with back-moving spring, when unblanking, panel of lock is left in latch hook the inner, and back-moving spring compressing latch hook rotates around its rotating shaft, makes latch hook can withdraw from doorframe and panel of lock easily, guarantees the lockset reliable operation.

In the utility model, described latch hook is formed by stacking by steady pin by at least two latch hook sheets, and rotating shaft installing hole and the dead bolt planker rotating shaft installing hole on the latch hook sheet passed in rotating shaft; One latch hook sheet is half sheet, and the thickness of half sheet latch hook sheet is corresponding with dead bolt planker thickness.Said structure can make latch hook directly link to each other with the dead bolt planker by rotating shaft, has saved the dead bolt that is used to install rotating shaft, makes that the utility model structure is simpler.

In the utility model, described latch hook is formed by stacking by steady pin by five latch hook sheets, and four rotating shaft installing hole and dead bolt planker rotating shaft installing holes on the latch hook sheet are passed in rotating shaft, on the latch hook sheet in the middle of the hook of latch hook is located at.Adopt five latch hook sheets, the latch hook sheet can adopt stamped, can reduce the manufacturing cost of pick-proof lock with the dead bolt assembly.

Description of drawings:

Fig. 1 is the utility model exploded sketch.

Fig. 2 is the utility model structural representation.

Fig. 3 is the utility model latch hook portion generalized section.

Fig. 4 has used pick-proof lock structural representation of the present utility model.

The specific embodiment:

In conjunction with Fig. 1, Fig. 2, shown in Figure 3: the pick-proof lock of present embodiment comprises with the dead bolt assembly: be connected with dead bolt on the dead bolt planker 1, dead bolt planker 1 is provided with the moving tooth 2 that matches with the lock core shifting block, and it is flexible that the moving part in the lock housing drives dead bolt.Dead bolt is a latch hook 3, is connected by rotating shaft 4 between latch hook and dead bolt planker, and latch hook can rotate around the axis, and latch hook is provided with back-moving spring 5, and back-moving spring one end is connected on the hook 6 of dead bolt planker, and back-moving spring one end is connected on the hook 7 of latch hook.

Latch hook 3 is formed by stacking by steady pin 8 by five latch hook sheet 3-1,3-2,3-3, and wherein, latch hook sheet 3-1 has three.Four rotating shaft installing hole and dead bolt planker rotating shaft installing holes on the latch hook sheet are passed in rotating shaft 4; One latch hook sheet 3-3 is half sheet, and the thickness of half sheet latch hook sheet 3-3 is corresponding with dead bolt planker thickness.On the latch hook sheet in the middle of the hook 7 of latch hook is located at.

Because pick-proof lock is with being provided with latch hook in the dead bolt assembly, lockset is when lock-out state, and panel of lock is oppressed latch hook the inner, and latch hook overcomes the elastic force of back-moving spring, and doorframe and panel of lock are locked together, makes lockset that good pick-proof performance be arranged.Because latch hook is provided with back-moving spring, when unblanking, panel of lock is left in latch hook the inner, and back-moving spring compressing latch hook rotates around its rotating shaft, makes latch hook can withdraw from doorframe and panel of lock easily, guarantees the lockset reliable operation.Latch hook of the present utility model directly links to each other with the dead bolt planker by rotating shaft, has saved the dead bolt that is used to install rotating shaft, makes pick-proof lock simpler with the dead bolt modular construction.Adopt five latch hook sheets, the latch hook sheet can adopt stamped, can reduce the manufacturing cost of pick-proof lock with the dead bolt assembly.

Fig. 4 provides a kind of pick-proof lock of pick-proof lock with the dead bolt assembly of having used.This figure has provided the flexible moving part structure of a kind of existing drive dead bolt.What deserves to be mentioned is that it is varied driving the flexible moving part structure of dead bolt, the lockset that any moving part textural association that this pick-proof lock is stretched with dead bolt assembly and drive dead bolt constitutes all is interpreted as not breaking away from protection domain of the present utility model.
