CN2539804Y - Billiard latch with multiple locking mechainsm - Google Patents

Abstract

The utility model discloses a billiard latch, comprising not only a latch body, a latch core and a locking mechanism comprising a side pillar billiard and a lock-in side pillar, but also a lock-in mechanism consisting of a magnetic billiard group. Without increasing the volume of the latch body, the utility model is made to have a dual structure of the magnetic billiard latch and the inner pressure type side pillar billiard latch by a subtle design, so the safety and the guard against theft are improved greatly, and any billiard latch with single structure can not be compared with the billiard latch with multiple locking mechanism.

Description

Cylinder lock with multiple locking mechanism

Technical field the utility model belongs to a kind of lockset, particularly relates to a kind of cylinder lock set.

The background technology cylinder lock is a kind of common lockset, and wherein a kind of magnetic cylinder lock is the rotation that magnetic patch by on the key and the relation of the magnetic pole between the magnetic bullet in the pellet shot from a slingshot group move pellet shot from a slingshot to control lock core.Also having a kind of side column inner pressed cylinder lock, is to utilize cooperating of pellet shot from a slingshot and side column, controls (referring to the ZL99233344.X) that lock core rotates relative to lock body by moving of side column.These two kinds of problems that are latched in are, all have only a locking mechanism, no matter any when being locked in independent use, its security performance and theftproof performance all are limited.

The technology contents the purpose of this utility model provides a kind of cylinder lock with magnetic cylinder lock and side column inner pressed cylinder lock double locking mechanism.The security performance of this lock and theftproof performance are much higher than the lock of any single locking mechanism.

The technical solution of the utility model comprises lock body, lock core, pellet shot from a slingshot, pellet shot from a slingshot is divided into magnetic bullet group and side column pellet shot from a slingshot, the magnetic bullet group is made up of magnetic bullet and common spring, the magnetic bullet hole that has mutual dislocation on the lock core and side column pellet shot from a slingshot hole are to adapt to different pellets shot from a slingshot, also have the side column groove on the lock core, the inboard of side column groove communicates with the side in side column pellet shot from a slingshot hole, and with side column pellet shot from a slingshot hole approximate vertical, the corresponding common spring hole that has with lock core magnetic bullet hole on the lock body, the diameter in the common spring hole on the lock body is less than the diameter in lock core magnetic bullet hole, magnetic bullet and common spring place respectively in lock core magnetic bullet hole and the lock body common spring hole, the corresponding square groove that also has with lock core side column groove on the lock body, each side column pellet shot from a slingshot all has a circle ∨ type groove on diverse location, be provided with locking side column in the side column groove, the inboard of locking side column is the ∧ type, can match with the ∨ type groove on the side column pellet shot from a slingshot, the outside of locking side column is a square, can match with the square groove on the lock body, locking side column is provided with step, with be fixed with pressing plate on the corresponding lock core side column of the step groove outside, between pressing plate and side column step, be provided with the side column spring.

During the utility model cylinder lock locking, side column groove on the lock core is corresponding with the square groove on the lock body, the inboard of locking side column is under the compressing of side column pellet shot from a slingshot outer wall, its outside is stretched in the lock body square groove, lock core can not rotate, and the common spring in the magnetic bullet group extend into and further locks lock core in the lock core simultaneously.When unblanking, after key inserts lockhole, have orthogonal on the key and correspond respectively to the magnetic patch and the tartar of magnetic bullet group and side column pellet shot from a slingshot, magnetic patch and tartar force the shift in position of magnetic bullet group and side column pellet shot from a slingshot respectively.At this moment, ∨ type groove on the side column pellet shot from a slingshot all overlaps, be on the straight line, locking side column is under the effect of side column spring, and its ∧ type inboard is slipped in the ∨ type groove on the side column pellet shot from a slingshot, withdraws in lock body square groove in the outside of locking side column, simultaneously, the magnetic bullet in the magnetic bullet group and the magnetic action that repels each other between the magnetic patch on the key force common spring to move in the lock body, and lock core can rotate.

The utility model is by ingenious design, can not increase under the long-pending situation of lock body, make lock have the double locking mechanism of magnetic cylinder lock and side column inner pressed cylinder lock simultaneously, its safety and theftproof improve greatly, are that the cylinder lock of any single locking mechanism is incomparable.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
