Idle clutch safe lock

Abstract

The invention discloses an idle clutch safe lock. The idle clutch safe lock comprises a lock body, an outer lock cylinder assembly and an inner lock cylinder assembly. The outer lock cylinder assembly comprises an outer lock cylinder and an outer lock cylinder unlocking device; and the inner lock cylinder assembly comprises an inner lock cylinder and an inner lock cylinder clutch device. According to the idle clutch safe lock, a combination structure that the outer lock cylinder assembly with the outer lock cylinder and the inner lock cylinder assembly with the inner lock cylinder are arranged in the lock body is adopted, the outer lock cylinder unlocking device arranged on the outer lock cylinder assembly and the inner lock cylinder clutch device arranged on the inner lock cylinder enable unlocking to be achieved when the outer lock cylinder assembly and the inner lock cylinder assembly are closed, and also enable the condition that when the outer lock cylinder assembly and the inner lock cylinder assembly are separated, the outer lock cylinder assembly idles and the inner lock cylinder keeps in the locking state to be achieved; and even though the force for rotating a key is too large, as the key idles in the outer lock cylinder, a lock body structure cannot be influenced and destroyed, the condition that the key is broken is avoided, and the lock body is accordingly protected. The lock is reasonable in whole design, compact in structure, higher in using safety and suitable for application and popularization.

Description

technical field [0001] The invention relates to an idle clutch safety lock head. Background technique [0002] Most of the existing safety lock heads are straight lock cylinders or cross lock cylinders in which the inner lock cylinder and the outer lock cylinder are locked in the same body, which mainly has the following disadvantages: one is that when the key is inserted from the outside of the lock body to unlock and the inner lock cylinder is opened at the same time, When the safety device is in the state, the key cannot be turned to unlock; the second is that when the inner lock cylinder opens the safety device, when the key is turned from the outside, because the inner lock cylinder cannot idle, the key may break due to excessive force, thereby destroying the inner structure of the lock and affecting Unlock normally. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art and provide a combi...
