Clutch lock

Abstract

The invention discloses a clutch lock, comprising a lock body, a lock cylinder which is axially sleeved in the lock body and can rotate, and a clutch base, and the lock cylinder is provided with a plurality of blade marbles with V-shaped grooves along an axis, and the blade marbles are elastic. The lock cylinder and the clutch base are respectively provided with a locking side column which is cooperated with the V-shaped groove on the blade marble and has elasticity, and a clutch pin with a clamping handle. The end of the clutch pin is a wedge shape. The clamping handle of the clutch pin is between the locking side column and the lock body. The lock body is provided with a clamping groove matched with the clamping handle of the clutch pin, and a wedge-shaped clamping groove cooperated with the wedge-shaped end of the clutch pin. The lock body is internally provided with a clutch pin clamping bead which contacts with the clutch pin in a radial manner and has elasticity. Since the clutch pin with the clamping handle is used, when the lock cylinder rotates, the lock cylinder joins with the clutch base through the clamping handle of the clutch pin, so as to achieve an objective of unlocking. The structure can greatly improve reliability of clutch of the lock cylinder and the clutch base, and a problem that a lock cannot be opened is thoroughly solved.

Description

technical field [0001] The invention belongs to locks, in particular to a clutch lock. Background technique [0002] In the existing lock, the lock cylinder of a kind of lock can rotate freely when in the locked state, so as to prevent the lock cylinder from being broken by inserting the lock cylinder with a tool and forcefully destroying the pins of the lock cylinder to open the lock. The lock core of this lock is composed of front and rear lock cores. The front lock core is connected with the rear lock core with elastic beads through the sleeve. When unlocking, the front lock core and the sleeve drive the rear lock core to control the clutch pin to realize The clutch of the rear lock cylinder. There are certain deficiencies in the structure of this lock. Sometimes the sleeve cannot drive the rear lock core so that the clutch pin cannot be controlled and cannot realize the engagement of the front and rear lock cores, resulting in the lock not being opened.
