A kind of idling structure of pin (blade) lock cylinder

Abstract

The invention discloses an idling structure of a pin (blade) lock core. The lock core is divided into a front lock core and a rear lock core. The locking side post matched with the groove, the locking side post is provided with a gap that can cooperate with the lock cylinder pin (blade), and the locking side post return spring is provided between the locking side post and the end wall of the locking side post groove; A lock pin chute is arranged on the rear lock core corresponding to the locking side column groove of the front lock core, a lock pin is placed in the lock pin chute, and a lock pin return spring is arranged between the end wall in the lock pin chute and the lock pin; The elasticity of the pin return spring is larger (smaller) than that of the locking side column return spring; at least one of the locking pin (locking side column) or the locking side column groove wall (lock pin chute wall) adopts an inclined plane to contact the other. The invention has simple and firm structure, strong reliability, and the anti-violence tool has good unlocking effect by prying and twisting the lock cylinder.

Description

technical field [0001] The invention belongs to mechanical locks, and in particular relates to an idling structure in which a pin lock core or blade lock core can rotate 360° relative to a lock body of the lock core when the lock is closed. Background technique [0002] At present, there is a mechanical lock that uses a side column structure to lock, in which a part of the lock core cannot idle 360 ​​degrees relative to the lock body of the lock core when the lock is closed. ability is poor. Another part of the lock cylinder can do 360° idling with respect to the lock body of the lock cylinder when the lock is closed. It is a three-layer structure with a rotating sleeve arranged between the traditional lock cylinder and the lock body, and the pins arranged on the rotation sleeve can cooperate with the lock cylinder and the lock body respectively to realize the idling of the lock cylinder. Although this lock can prevent violent tools from prying and twisting the lock cylind...

AI Technical Summary

Problems solved by technology

Although this kind of lock can prevent violent tools from prying and twisting the lock core, it has the disadvantages of complex structure, cumbersome processing technology, high production cost, and the need to increase the diameter of the lock body.
