Cylinder, lock and unlocking key

Abstract

The invention provides a cylinder, a lock and an unlocking key. According to the cylinder, the lock and the unlocking key, an upper cylinder body and a middle cylinder body are in locked linkage through an authorization assembly, and the upper cylinder body and a lower cylinder body are in separated connection through a separation mechanism; when the cylinder is locked, under the external acting force, the upper cylinder body rotates in the axial direction to drive the middle cylinder body to rotate, the middle cylinder body drives the separation mechanism to act so as to enable the upper cylinder body and the lower cylinder body to be separated, and therefore idling of the cylinder can be realized; and when the cylinder is unlocked, under the authorization acting force of the unlocking key, locked linkage of the upper cylinder body and the middle cylinder body are relieved, the unlocking key is rotated to drive the upper cylinder body to rotate, the middle cylinder body is in a staticstate, the separation mechanism enables the upper cylinder body and the lower cylinder body to be in linkage, the upper cylinder body drives the lower cylinder body to rotate in the axial direction,and therefore unlocking of the cylinder can be realized. The cylinder, the lock and the unlocking key have the advantages that if the unlocking key is incorrect, the cylinder idles, if the unlocking key is correct and is authorized, the cylinder is unlocked, and therefore the phenomenon that the key and the cylinder are damaged due to the fact that the unlocking key is incorrect and / or unauthorized can be avoided; and a cylinder main body of the idling cylinder is not fixed, an electric drill does not have an acting point, violent damage is difficult, and therefore the anti-drilling performance of the cylinder can be improved.

Description

technical field [0001] The invention relates to the field of locks, in particular to a lock cylinder, a lock and an unlocking key. Background technique [0002] At present, the lock cylinders used by many power and energy companies are mostly mechanical pins and spring lock cylinders. Authorization is realized by locking the key. This type of lock cylinder can often be unlocked after the key tooth shape is correct. The anti-theft performance is low and it is easy to be unlocked by technology; In addition, authorizing by locking the key can cause strong twisting to destroy the lock cylinder and key. Contents of the invention [0003] The main purpose of the present invention is to provide a lock cylinder, lockset and unlocking key to solve the technical problem that the lock cylinder in the prior art is easy to be unlocked by technology or by violence. [0004] In order to achieve the above object, the first aspect of the present invention provides a lock cylinder, includi...
