Abstract

The utility model provides an anticollision wheel lock, which includes a lock body, a lock core, a latch hook, a lock bolt and a lock bolt spring, which also includes an anticollision bolt and an anticollision spring, the backs of the latch hook and the lock bolt are provided with a bayonet, the anticollision bolt is a framework structure whose two sides are matched with a guide slot of the lock body for placing in the lock body, the anticollision spring is arranged between the anticollision bolt and the lock body, an end strut rail of the anticollision is matched with the bayonet, the back side of the anticollision bolt is arranged in a stirring slot of the lock bolt and abuts against a dog driver. The wheel lock can effectively prevent the weight from striking the lock body to open the lock, which has a good theft proof effect and a simple structure, which is easy to implement.

Description

Anti-collision wheel lock

Affiliated technical field

The utility model relates to lock, and particularly a kind of anti-collision wheel lock is fit to motorcycle and bicycle and uses.

Background technology

In prior art, the theftproof lock that generally is used for motorcycle and bicycle is made up of lock body, lock core, latch hook, spring and dead bolt.Latch hook is a reverse U shape, and the one end is articulated in an end of lock body, and the other end is a plug that has breach, dead bolt is placed in the lock body, and its front end is equipped with spring over against the breach of latch hook in the lock body of its rear end, lock core places in the lock body of dead bolt below, and its driving lever places in the allocating slot of dead bolt bottom.The dead bolt front end is inserted in the breach of latch hook under the situation of locking, promptly locks.In the time of need unblanking, stir lock core by key, make its driving lever drive the breach that dead bolt withdraws from latch hook, latch hook is not retrained by dead bolt, so just lock can be opened.This lock construction is simple, makes latch hook with hard steel, can effectively prevent the robber with saw blade, screwdriver with open.Yet, in use find, people are as long as clash into the rear end of lock body with hammer, just move rapidly with respect to lock body with the dead bolt of lock body socket backward, the lock-tongue port that breaks away from latch hook, lock just can be opened, and is very quick, this is the car method of stealing that the confirmed thief often takes, and this defective of prior art also is not well solved so far.

Summary of the invention

In order to solve the problem of existing motorcycle anti-theft oil lock theftproof performance difference, the utility model provides a kind of anti-collision wheel lock, and this wheel lock can prevent to unblank by bump effectively, and simple in structure, implements easily.

Above-mentioned task realizes by this way: this anti-collision wheel lock comprises lock body, lock core, latch hook, dead bolt and latch bolt spring.It also comprises a crashproof door bolt and crashproof spring, also have a bayonet socket at the back side at latch hook lock-tongue port place, crashproof door bolt is a closed-in construction, cooperate with the guide groove of lock body with its both sides and to place in the lock body, crashproof spring is installed between crashproof door bolt and the lock body, the front cross member of crashproof door bolt and bayonet fittings, back strut rail place in the allocating slot of dead bolt and near the driving lever of dead bolt.

The operating principle of the technical program is such: when blocking, under the effect of crashproof spring, the front rail of crashproof door bolt is stuck in the bayonet socket of latch hook, at this moment, rear end with iron hammer bump lock body, even dead bolt breaks away from the lock-tongue port of latch hook, and crashproof door bolt still firmly is stuck in the bayonet socket of latch hook, latch hook can't be opened; And when using key rotation lock core, its driving lever goes to wide position from narrow position, removes the promotion dead bolt and moves backward, breaks away from outside the lock-tongue port, and the back strut rail of also oppressing crashproof door bolt pushes away crashproof door bolt forward, makes it front cross member and breaks away from bayonet socket, and latch hook is unfettered, so lock can be opened.After locking, crashproof door bolt and dead bolt are returned to reset condition again.

From improvement structure of the present utility model with and operating principle as can be known: the technical program can prevent from hard thing lock to be rushed open effectively, and simple in structure, reliable, on original theftproof lock, implement easily.

The specific embodiment

Referring to Fig. 1 to Fig. 4, a kind of anti-collision wheel lock comprises lock body 1, lock core 2, latch hook 3, dead bolt 4 and latch bolt spring 5.

The utility model also comprises crashproof door bolt 6 and the crashproof spring 7 that is installed in the lock body 1.The back side at latch hook 3 lock-tongue ports 8 places also has a bayonet socket 9.Crashproof door bolt 6 is a rectangle closed-in construction, and its both sides place in the guide groove 10 of lock body 1, and crashproof spring 7 is installed between crashproof door bolt 6 and the lock body 1.Under the effect of crashproof spring 7, crashproof door bolt 6 front cross members 11 are stuck in the bayonet socket 9 of latch hook 3, and strut rail 12 is flat in the allocating slot 13 of dead bolt 4 thereafter, near the driving lever 14 of lock core 2.Allocating slot 13 will leave the spacing that back strut rail 12 moves, so that crashproof door bolt 6 front cross members 11 are pushed away the bayonet socket 9 of latch hook 3 when driving lever 14 rotates.

As shown in Figure 3, can on the latch hook 3 of pupil bayonet socket 9 both sides, respectively open a guide groove 15 crashproof door bolt 6 front ends two inboards and also be provided with the plush copper 16 that cooperates with guide groove 15, make when originally being locked in blocking more firm.
