Description

A kind of anti-ring lock that knocks

The utility model relates to a kind of ring lock, particularly a kind of anti-ring lock that knocks.

The at present general anti-ring lock that knocks adopts the mode of reinforcing dead bolt and lock ring, but because at present more ring lock is less, and dead bolt and lock ring are subjected to maximum shearing when being knocked, thin impaired the fractureing easily of dead bolt and lock ring can not prevent to knock dead bolt or the lock ring that ring lock damages ring lock effectively.

The purpose of this utility model provides a kind of can effectively preventing by the ring lock that knocks and damage.

To be that design is a kind of anti-knock ring lock to the technical solution of the utility model, comprises lock body, dead bolt, lock ring, and it is characterized in that: the dead bolt end face is an inclined-plane, and an inclined-plane that cooperates with the dead bolt inclined-plane is arranged on the lower end of lock ring.

The utility model has the advantages that to make and prevent that effectively ring lock from being knocked and damaging.

Below in conjunction with accompanying drawing the utility model is elaborated,

Accompanying drawing is the partial cutaway schematic of the utility model figure, comprises lock body 1, dead bolt 2, lock ring 3 among the figure, it is characterized in that: dead bolt 2 end faces are an inclined-plane 4, and an inclined-plane 5 that cooperates with dead bolt 2 inclined-planes 3 is arranged on the lower end of lock ring 3.When ring lock pins during use, when knocking lock body 1 with external force, lock ring 3 is subjected to a power that makes progress, lock ring 3 inclined-planes 5 resolve into the inclined-plane 4 that power that a lateral force and makes progress is passed to dead bolt 2 with power, and dead bolt 2 is subjected to lateral force that transmits on inclined-plane 4 and the power that makes progress, and lock ring 3 also is subjected to a horizontal power simultaneously, because lock body 1 is firmer, make the lateral force that external force is decomposed not play damage to dead bolt 2, lock ring 3, and the power that makes progress after decomposing greatly reduces and makes dead bolt 2, lock ring 3 is not fragile.
