Description

Fixed theftproof lock

Technical field:

The utility model relates to a kind of theftproof lock, especially a kind of fixed theftproof lock that is used for bicycle, tricycle, motorcycle etc.

Background technology:

The various anti-theft lock for vehicle of selling on the existing market mostly are reinforcing bar U-shaped lock or coarse-wire rope U-shaped or ring lock.Stolen for preventing vehicle (mainly being bicycle, tricycle, motorcycle etc.), all be to pin with the wheel of above-mentioned lock with vehicle, perhaps vehicle and a certain fixture are pinned.Such lock has advantage easy to carry, but such is being latched in the shortcoming that lock rope or lock pin are easily sheared with wiring clip by the thief, is easy to destroyedly, and its anti-theft effect is relatively poor.Simultaneously, such lock also exists the shortcoming that vehicle is easily arbitrarily moved as it is directly locked onboard, and the method that thief such as employing are moved is stolen car, and then such lock will lose antitheft effect.

Summary of the invention:

The purpose of this utility model provides a kind of fixed theftproof lock that can effectively stop the thief to cut off dead bolt or move the capable robber of vehicle.

The purpose of this utility model is achieved by the following technical solution:

Fixed theftproof lock described in the utility model, comprise a lock body framework, the ground that is used for storage of cars is fixed in the bottom of this lock body framework, is characterized in: respectively be provided with one on the two side of lock body framework and be the vertical elongated slot of symmetrical distribution with the middle axial plane of lock body framework; Respectively be provided with a latch hook in the elongated slot, be symmetrical distribution, respectively be provided with a fixed axis near the bottom of latch hook and make latch hook be and rotatingly to be connected with the lock body framework with the middle axial plane of lock body framework; Be provided with a latch hook connecting rod near the bottom of two latch hooks, its two ends respectively flexibly connect axle by one and are connected with two latch hooks; Also be provided with a latch hook extension spring near the bottom of two latch hooks, its two ends are connected with latch hook; The trapezoidal shape that the top of two latch hooks respectively is provided with is one that stretch out to lock body framework inside, be symmetrical distribution with the middle axial plane of lock body framework protrudes, and the spacing between its front end face just in time can be blocked the steel ring of corresponding vehicle and the valve inside that is unlikely corresponding vehicle is stuck; Be provided with spoonful latch mechanism near the bottom that the top trapezoidal shape that is positioned at its corresponding latch hook on the sidewall of lock body framework protrudes, its lock core is fixed in this lock body framework, and its dead bolt is positioned at the dead bolt blind hole that the lock body framework is offered; The front end of dead bolt is an inclined plane shape, and the part of its inclined plane shape can stretch in the corresponding dead bolt hole of offering on the corresponding latch hook, and the rear end of dead bolt is provided with a dead bolt top spring.

Fixed theftproof lock described in the utility model, its further characteristics are: be provided with a block in the front end of lock body base of frame and rear end.

The utility model has the advantages that: it is fixed in (1) on the ground of storage of cars, in case vehicle is lockable, can not be moved, and avoid the existing lock that directly pins vehicle effectively, improve the anti-theft effect of vehicle effectively unavoidably by the mobile together shortcoming of chain band car; (2) its latch hook structure must be opened two latch hooks simultaneously because the trapezoidal shape face of latch hook links, and just can remove vehicle, and the difficulty of stealing car is increased; (3) because the locking face of its latch hook structure is the trapezoidal shape face that is difficult to shear, adopt the method for shearing will be difficult to steal car, increased its antitheft effect; (4) all be provided with block before and after its bottom, the robber is difficult to shear lock mechanism of car of the present utility model with cutting implement, and its theftproof performance further improves.
