The lock core is drawing proof and knocking proof and prevents the damage to other tools. The arc shaped matching between the arc shaped bayonet and the front head of the lock chain as an axle center point is adopted, the lock tongue is improved to be hole groove shaped and is positioned with the lock core foot, and the lock tongue positioned in the locking plate can perform an anti-knocking function.

Description

A kind of lockset

Technical field

The utility model relates to a kind of lockset.

Background technology

Present chain lock, its lock body often is made up of the block of metal material, again at interior lock core, dead bolt and the chain of being provided with, this structure, its dead bolt is damaged in striking being hit easily, and chain and lock body also are sheared easily or cut, the anti-poor performance of pulling out of lock core.

Summary of the invention

The purpose of this utility model is that a kind of anti-performance height of cutting is provided for the deficiency that solves above-mentioned technology, and lock body and whole anti-saw performance are good, and can prevent pulling out the anti-a kind of lockset that strikes.

In order to achieve the above object, a kind of lockset that the utility model is designed, be that rotation snaps in closing component structure between the arc bayonet socket of described dead bolt front end and the preceding chieftain of chain, on dead bolt, be provided with hole slot with the lock core foot coupling, lock core foot inserts in the hole slot, and dead bolt rotates with the rotation of the lock core foot of lock core.Described lock body is formed by stacking by locking plate, is provided with definite corresponding aperture on the superimposed locking plate of determining the position.The steel ball chain that described chain is made up of steel ball, wire rope and joint cover, chieftain before chain one end connects, the other end is fixed in the lock body.Fixed structure can be in the chain end the I-shaped rear foot to be set, and by steady pin I-shaped rear foot pin is fixed in the lock body again.In order to improve the pick-proof performance of lock core, be provided with screening glass at the key socket face of lock body, outside screening glass, be provided with the laminate backsheet that superimposed locking plate is formed.

The resulting a kind of lockset of the utility model is concatenated into the steel ball chain by steel ball, bending and steel disc lock body combination arbitrarily, and the steel ball chain rear foot is fixed in steel disc lock body one stomidium, and the chieftain inserts in another stomidium of steel disc lock body before the steel ball chain, can open sealed.

The resulting a kind of lockset of the utility model, in the lock body that locking plate is overlapped into, cooperate lock core, be furnished with tooth-engraved key, key inserts lock core rotation 45 degree to 90 degree, but the rotation of interlock dead bolt, the chieftain inserts in the lock body opening before the steel ball chain, key rotates back to former, the dead bolt rotation, and key is extracted, preceding chieftain is sealed, and key inserts to revolve and turn 90 degrees preceding chieftain's unlatching.

The lockset that present embodiment obtains, the composition of its chain structure reaches steel ball, joint is overlapped via the above carburizing heat treatment of Rockwell hardness HRA73 degree, it is 1.8 centimetres that every steel ball polyphone engages, and reaches to cut with cutting pliers to press afterburning 100 pounds to cut and constantly be standard-required, reaches that chain is anti-to be cut.

The utility model can adopt the steel ball chain to add carburizing heat treatment can reach anti-saw purpose, and lock body can be colded pressing more than the plate carburizing heat treatment HRA73 degree by A3, take counterbore lamination mode riveted after, saw all can be prevented in whole any position.

The lockset that the utility model provides, pellet shot from a slingshot, following pellet shot from a slingshot, pellet shot from a slingshot spring accumulation size and lock core bore size are zero on it, add the heat treatment of T9A steel wire pellet shot from a slingshot spring again, increase the anti-intensity of pulling out, the increasing pellet shot from a slingshot is differential, plays the anti-effect of pulling out.

The lockset of the utility model design adopts dead bolt open arc shape bayonet socket to cooperate for the arc type of AnchorPoint with the preceding chieftain of chain, dead bolt transformation of the way hole-and-slot and lock core foot location, and dead bolt is positioned at can play the anti-effect of striking in the locking plate.

The bulk heat treatmet of the utility model product, after the plating, the combination of steel ball chain is by the preparation of crosslinked polyethylene thermoplastic tube, and lock body is cooperated by polyethylene hot pressing material, plays the effect that does not damage other instrument.

The resulting a kind of lockset of the utility model, chain prevents cutting the performance height, lock body and whole anti-saw, lock core is anti-to be pulled out, and prevents striking other instrument of anti-tamper.
