Lock cylinder clutch prying-resistant mechanism

Abstract

The invention discloses a lock cylinder clutch prying-resistant mechanism. The lock cylinder clutch prying-resistant mechanism comprises a lock cylinder assembly and an abutting assembly, wherein thelock cylinder assembly comprises a lock cylinder shell, a lock cylinder rotating block rotatably arranged on the lock cylinder shell and a clutch structure; the clutch structure is movably arranged onthe lock cylinder shell and capable of abutting against the lock cylinder rotating block; the abutting assembly comprises a motor and a transmission block; the transmission block comprises a baffle;the motor drives the transmission block to slide to enable the baffle to abut against the clutch structure; and the clutch structure clamps the lock cylinder rotating block, so that the lock cylinderrotating block is unable to rotate relative to the lock cylinder shell, and the anti-prizing effect is achieved. Through the design, a lock cylinder is mounted on a front panel, and a hole does not need to be formed in the front panel or a key hole opening structure does not need to be made on the front panel, so that attractiveness is kept; and even if the front panel is pried, a door still cannot be unlocked through non-electric drill tools such as a screwdriver, so that both appearance and safety are considered.

Description

technical field [0001] The invention relates to a lockset, in particular to a lock cylinder clutch anti-tampering mechanism. Background technique [0002] Electronic door locks have been widely used at present. Electronic door locks in the prior art can be unlocked using keys or biometric technology to improve the convenience of unlocking; and in the existing door lock structure, electronic locks are generally designed with locks inside. When the electronic part is abnormal, insert the key into the lock cylinder to open the door mechanically, so as to avoid the failure to open the door due to abnormal electronic unlocking. [0003] There are two ways to install the lock cylinder on the market, one is to install the lock cylinder in the lock body, which is called a real mortise, and the other is to install the lock cylinder on the front panel, which is called a false mortise. The advantage of the real mortise is safety, that is, after the panel is pried off, the key still ne...

AI Technical Summary

Problems solved by technology

The advantage of the real mortise is safety, that is, after the panel is pried off, the key still needs to be used to unlock the lock, but the disadvantage is that it needs to insert the key from the front of the door, which results in the need to open a hole or make a keyhole on the front panel structure, which will destroy the integrity of the appearance of the panel or cause limitations to the design of the appearance; the disadvantage of the false ferrule is that after the panel is pried off, it can be unlocked by using non-electric drill tools such as screwdrivers, but the advantage is that the lock The core can be designed at any position of the panel according to the appearance requirements, such as at the bottom of the panel, etc.

[0004] Therefore, there is certain defect in the installation mode of above two kinds of lock cylinders.
