Description
One, technical field
The utility model relates to a kind of lockset, especially a kind of pick-proof lock.
Two, background technology
Existing simple and easy lock such as Shanghai refinement cattle head lock on the market only has a dead bolt, and its dead bolt structure is the cuboid that an end is cut into the inclined-plane.This is locked in crack between a door and its frame closely the time, is easy to be inserted in crack between a door and its frame dead bolt place with sheet-like articles such as identity card, magnetic card, rechargeable cards and unblanks, thereby lost the effect of door lock.
Three, summary of the invention
The purpose of this utility model provides a kind of improved pick-proof lock, and it is provided with shallow slot on the dead bolt inclined-plane, can prevent effectively that sheet-like article from unblanking.
For achieving the above object, the utility model is achieved in that it comprises lock body, dead bolt, dead bolt inclined-plane, and described dead bolt inclined-plane is provided with one to three road shallow slot, wherein establishes two road shallow slots on the dead bolt inclined-plane for preferred.
Because the utility model is provided with shallow slot on the dead bolt inclined-plane, sheet-like article will fall in the shallow slot when crack between a door and its frame inserts, can't continue advancing sliply, stop the dead bolt slip, thereby reach the purpose of pick-proof.
Four, description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 cuts open front view according to the pick-proof lock office that the utility model proposes.
Fig. 2 is the vertical view of Fig. 1.
Sign in the accompanying drawing is represented respectively:
1. dead bolt inclined-plane 2. shallow slots 3. dead bolts 4. lock bodies
Five, the specific embodiment
Can find out that from Fig. 1 and Fig. 2 the utility model twice shallow slot 2 is located on the dead bolt inclined-plane 1 of dead bolt 3, other lock body 4 structures are not done any change.During production, as long as processing two road shallow slots 2 on the dead bolt inclined-plane 1.Establish on the dead bolt inclined-plane 1 together and three road grooves also possess tamper-resistant function, just its practical application effect is not as two road grooves.Therefore during application, sheet-like article will fall in the shallow slot 2 when crack between a door and its frame inserts, and stop the slip of dead bolt 3 and reach the purpose of pick-proof.
