Description

Theft-deterrent lock

The utility model relates to a kind of theftproof lock, and it is specially adapted to lock bicycle.

It is reported that it is varied to be used for antitheft lock at present, though these theftproof locks have played positive role aspect antitheft, but still have in various degree drawback,, key core big as the lock body volume easily is removed, and theftproof performance is desirable not to the utmost, and it is disconnected etc. that key is easily bumped.

The purpose of this utility model is, provide a kind of reasonable in design, volume is little, theftproof good can, safe and reliable, the theftproof lock that key core is difficult for being removed.

Technical solution of the present utility model is that existing theftproof lock is improved.In order to dwindle the volume of lock body, it is disconnected to prevent that key from being bumped, and key core is horizontal in lock body, makes it parallel with dead bolt, and is provided with dead bolt dial that both sides have an eccentric shaft and the moving part that is connected with eccentric shaft on dead bolt dial, the key core in lock body.In order to prevent that key core is removed, improve theftproof performance, the pellet shot from a slingshot hole bottom lock body is contained in the lock body that is positioned at key core top with pellet shot from a slingshot and pellet shot from a slingshot spring.For the ease of the lock bicycle, on the upper surface of lock body, also be provided with the fastener that sets firmly lock body, by fastener lock body is fixed on the forward and backward fork of bicycle.In order to prevent to lose after lock bridge from taking off.Big side at lock body has the lock bridge jack.It is lockhole that its lock bridge jack has a hole at least.

The utility model owing to key core is horizontal in lock body, therefore dwindled the distance at lock body two ends, that is has dwindled the volume of lock body compared with the prior art, has solved key simultaneously and has easily been bumped disconnected possibility.In addition, because pellet shot from a slingshot and pellet shot from a slingshot spring have been placed the top of key core, so key core packs into and just can't take out behind the lock body, thereby improved theftproof performance.

Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.

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