Abstract

The utility model relates to a lock with spring structure, comprising a spring lock and a vehicle lock, which is provided with a lock sleeve, a lock core, a slideway of the lock sleeve and the lock core, a spring or a locking blade, a reset spring and other members. A self-locking slot is arranged in an end of the spring or the locking blade, and corresponding to the self-locking slot; a self-locking slot is arranged in the inner wall of the slideway of the lock sleeve or the lock core. The utility model has the advantage of simple structure, good safety, and enabling to effectively prevent the lock unlocking with skills through inserting a non-key tool into the key hole.

Description

A kind of lock with billiards structure

Affiliated technical field

The utility model relates to a kind of mechanical lock, particularly has the lock of billiards structure.

Background technology

Existing lock with billiards structure comprises cylinder lock and lock, this lock is provided with lock tube, be embedded with the lock core that can rotate relative to lock tube in the lock tube, in lock tube and lock core, be provided with more than one slideway, lock tube communicates with corresponding slideway on the lock core, slidably pellet shot from a slingshot is installed in this slideway, and this pellet shot from a slingshot is called locking plate in lock, has the key hole in lock core.When inserting with key when operating in the key hole, make directed the moving of pellet shot from a slingshot in each slideway, and make pellet shot from a slingshot be in one can to make lock core, rotational lock core again, the realization purpose of unblanking relative to the position that lock tube freely rotates.The weak point of this lock is, when inserting key hole operation with other instrument beyond the key, can reach equally pellet shot from a slingshot is slided, and make pellet shot from a slingshot be in one can to make lock core relative to the position that lock tube freely rotates, reach the purpose of unblanking.

Summary of the invention

The purpose of this utility model provides a kind of lock with billiards structure, and this lock has only to use key operatedly just can unblank, and uses other instrument beyond the key to insert to carry out in key hole the craftsmenship purpose of unblanking of unblanking then not reach.

The technical solution of the utility model is: this lock has adopted above-mentioned billiards structure, has self-locking grooves at an end of pellet shot from a slingshot or locking plate, and is corresponding with the self-locking grooves of pellet shot from a slingshot or locking plate, having self-locking grooves on the slideway inwall of lock tube or on the slideway inwall of lock core.Through adopting said structure, when inserting with key when operating in the key hole, because key tooth axially consistent to the active force of pellet shot from a slingshot and lock tube and lock core slideway, thereby can make pellet shot from a slingshot be placed in lockset position of coupler in the clear, realize that rotation unblanks.And when inserting with other instrument beyond the key when operating in key hole, put in place in order blindly to stir pellet shot from a slingshot, pellet shot from a slingshot is subjected to a kind of extruding force that axially tilts with slideway in slideway, make the lock core fine rotation and make between the slideway of lock tube and lock core and angle occurs, and force pellet shot from a slingshot to slide, but owing to be provided with self-locking grooves, this active force then make form between the self-locking grooves of pellet shot from a slingshot and the self-locking grooves on lock tube or the lock core slideway staggered, engagement phenomenon between similar gear teeth appears, make pellet shot from a slingshot locked, can not arrive the precalculated position, thereby can not unblank.

The utility model has the advantages that, simple in structure, can prevent effectively that inserting the key hole with other instrument beyond the key unblanks, and has improved the safety of lock.

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

Description of drawings

Fig. 1 is the utility model structure sectional view.

Fig. 2 analyses and observe (amplification) figure for Figure 1A-A.

Fig. 3 is the pellet shot from a slingshot locking state diagram that the utility model forms when operating with non-key-shaped tool.

The specific embodiment

According to Fig. 1 and Fig. 2, the utlity model has lock tube 1, in lock tube 1, be embedded with lock core 2.Back-moving spring 3, pellet shot from a slingshot 4, pellet shot from a slingshot 5 are installed in the slideway of lock tube 1 and lock core 2 successively, have self-locking grooves 4-1 at an end of pellet shot from a slingshot 4, and be corresponding with this groove, has self-locking grooves 2-1 on the slideway inwall of lock core 2.According to Fig. 3, because the operation of non-key unlocking, force lock core 2 slideways and the lock tube slideway upper angle that staggers, the self-locking grooves that is set up when pellet shot from a slingshot 4 is upwards slided locks.

Claims

1. lock with billiards structure, be provided with lock tube, lock core, lock tube and lock core slideway, pellet shot from a slingshot or locking plate, back-moving spring etc., it is characterized in that: an end of described pellet shot from a slingshot or locking plate has self-locking grooves, corresponding with this self-locking grooves, having self-locking grooves on the lock tube slideway inwall or on the lock core slideway inwall.
