Lock body structure with function of double-cylinder synchronous control for unlocking

Abstract

The invention discloses a lock body structure with the function of double-cylinder synchronous control for unlocking. The lock body structure comprises a lock head and a key. An inner lock cylinder mounting hole and an outer lock cylinder mounting hole are formed in the two ends of an inner cavity of the lock head correspondingly and used for mounting an inner lock cylinder and an outer lock cylinder correspondingly. The inner lock cylinder and the outer lock cylinder can rotate in the lock head. A shifting wheel used for shifting a lockset is further mounted on the lock head. A penetrating through hole is formed in the center of the shifting wheel. The two ends of the shifting wheel are connected with the inner lock cylinder and the outer lock cylinder in a sleeving mode correspondingly.The shifting wheel can be driven to rotate through simultaneous rotating of the inner lock cylinder and the outer lock cylinder. An inner locking mechanism and an outer locking mechanism are mounted between the inner lock cylinder and the lock head as well as the outer lock cylinder and the lock head correspondingly. An inner key groove and an outer key groove which are provided with special bitsare formed in the key. The inner key groove and the outer key groove are used for decoding the inner locking mechanism and the outer locking mechanism correspondingly. The lock body structure adopts the inner and outer double-cylinder structural design, during unlocking, a lock body can be opened by simultaneous successful verification of the two key clamping grooves of the inner lock cylinder andthe outer lock cylinder during unlocking, and thus the safety performance of the lock body is improved greatly.

Description

Technical field [0001] The invention relates to the technical field of lock core structures, in particular to a lock body structure with dual cores for synchronously controlling unlocking. Background technique [0002] Nowadays, the commonality of lock cylinder structure has become more and more common. In the market, it is generally a double-hole single lock cylinder. Different lock cylinders are distinguished according to different groove structures. Nowadays, common door locks only need to be opened outside. It is no longer necessary to use a key to lock the inside. The lock body can be locked by directly lifting the inner handle. At the same time, the lock knob can also be used to achieve the purpose of locking. Therefore, the inner side of the lock body with the double hole single lock core structure in the prior art The keyhole and the lock cylinder are often in an idle state, and their application value has not been truly exerted. In addition, the existing double-hole sin...

[0002] Nowadays, the common structure of lock cylinders has become more and more common. In the market, there are generally double-hole single lock cylinders. Different lock cylinders are distinguished according to different groove structures. Nowadays, the common door locks only need to be opened from the outside. It is no longer necessary to use a key to lock the interior. The lock body can be locked by directly lifting the inner handle. At the same time, the lock knob can be used to achieve the purpose of locking. The lock hole and the lock cylinder are often in an idle state, and their application value has not really been exerted

And the lock body of existing double-hole single lock cylinder form also has the problem that anti-theft performance is lower
