Summary of the invention
The purpose of this utility model is, overcomes the defective that above-mentioned prior art exists, and provides a kind of simple in structure, with low cost and have a lock of preferable anti-theft effect.
The technical solution of the utility model is: it comprises dead bolt, and the inclined-plane of described dead bolt is provided with fin.
Because the utility model dead bolt inclined-plane is provided with fin, is blocked by fin when thin slice withstands on the inclined-plane, thin slice can further not slide, and therefore, dead bolt can not retract in the lock body, thereby has played antitheft effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of dead bolt of the present utility model.
The specific embodiment
Lock body part of the present utility model is a prior art, and therefore, lock body part no longer describes in detail.Shown in Figure 1, the utility model difference with the prior art only is the dead bolt part, and dead bolt of the present utility model inclined-plane is provided with fin or groove, dead bolt top and doorframe sliding-contact at closing time, and fin or groove can not influence closes the door.But when with thin slice when heading into outdoors, lived by fin or groove shelves, thin slice can not continue to continue and slides inwards, therefore, dead bolt can not retract in the lock body, has played antitheft effect.
