Background technology

No. 85206672 novel patent case (as shown in Figure 1) announced in the at present general steel cable lock that uses Taiwan in most of as on April 11st, 1998, it mainly comprises a lock body 1, this lock body 1 inside is provided with a core 10, core 10 can drive steel ball 11 and produce telescopic action, but steel ball 11 clips are in the groove 13 of latch hook 12, the control steel cable lock is the locking or unlocking state, but this steel cable lock, its assembling is quite complicated, and key A also can take out easily when unblanking, causing the user to recognize unblanks or locking at this moment, and take for is locking, when wanting locking, needs to use key A turn core 10 to rotate to make in the steel ball 11 again and contracts, so quite trouble is consuming time, utilize steel ball 11 used, cause the burglar to knock lock body 1 quite easily, make the steel ball 11 in the core 10 flick the formation unlocking condition as the circular groove 13 of clip latch hook 12, thereby lose antitheft effect fully, so be difficult to reach practicality in the use.

The utility model content

It is a kind of easy to assembly that the purpose of this utility model is to provide, but automatic blocking, the steel cable lock that the back key of unblanking can't take out.

For achieving the above object, technical solution of the present utility model is: a kind of steel cable lock, include: a lock body, be provided with lock core hole and storage tank in this lock body, the side of storage tank is penetrated with the clip hole, and the opening part in clip hole is equipped with flange, the side of lock body is installed with cable wire, the end in addition of cable wire is provided with latch hook, and lock shackle is provided with groove, and the surface of lock body convexes with several fixed legs; One core is located in the lock core hole, and core is provided with the drive piece; One block is located in the clip hole, and the rear end of block is provided with spring; One chock is enclosed in the end in clip hole; One protecting cover covers on the fixed leg of lock body, and protecting cover is provided with several embeddings hole; The relative position place of this lock core hole side is provided with chute, and the top of chute is provided with a conduit, is provided with spring in this conduit, and the front end of conduit is provided with stop edge, drives piece and is provided with pushing and pressing part, and the end of pushing and pressing part is provided with fixture block; One bayonet lock is located in the storage tank.

Described steel cable lock, wherein the chute in the lock body is curved, the corresponding arc that is made as of this pushing and pressing part.

After adopting said structure, lock body has the following advantages:

1, simple structure of the present utility model, the manufacturing assembling is quite convenient, can save manpower and cost.

2, since when unblanking key can't take out, so the user can be easy to judgement rapidly and appear as unlocking condition, can not take for is the locking situation, and loses antitheft effect.

3, the latch hook of cable wire does not need can insert in the clip hole by key operated, so can reach blocking automatically, quite saves time conveniently when therefore operating.

4, bayonet lock of the present utility model is subjected to stopping of pushing and pressing part, because pushing and pressing part is curved, so its contact area is bigger, thus can bayonet lock flick easily because of being subjected to knocking afterwards, cause latch hook to be unlocked, so anti-theft effect is preferable.
