Anti-theft lock cylinder, lockset and key thereof

Abstract

The present invention relates to the technical field of locks, in particular to an anti-theft lock cylinder, a lock and a key thereof, wherein the anti-theft lock cylinder is provided with a hidden verification device in the lock case so that a non-original key or a master key is inserted, when When the blades or pins are exposed, the test is invalid, that is, the driving part in the lock case cannot be tested. When the blades or pins are hidden, the master key cannot directly touch the operation test, so it can only achieve the result of idling, and finally cannot move the pins or pins. For complete unlocking, the hidden verification anti-theft device can prevent technical opening, and its idling structure can prevent violent rotation opening, and the comprehensive security is extremely high.

Description

An anti-theft lock cylinder, lock and key therefor technical field [0001] The present invention relates to the technical field of locks, in particular to a kind of anti-theft lock cylinder, locks and keys thereof. Background technique [0002] At present, there are many types of locks on the market with different structures. Mechanical locks are the most widely used in people's lives. The lock is not affected by occasions and environments, and has high stability. As people's security requirements for lock products are also higher and higher, the market generally adopts hidden keyholes through electronic Control to avoid violent unlocking, which increases the security level of locks to a certain extent, but whether it is fingerprint locks, electronic passwords Locks, face recognition locks, retina recognition locks, radio frequency locks, magnetic locks, etc., must be equipped with mechanical lock cylinders as a fire emergency. And the mechanical lock cylinder is sti...

[0005] Locks cannot fully play the role of anti-theft, which increases people's sense of insecurity

[0006] Patent CN201310134360.6 provides an automatic door lock, idling lock cylinder and automatic clutch key that prevent technical opening, wherein the hidden verification device is set on the lock cylinder of the idling lock cylinder, although the invention can effectively prevent technical opening and safety High security, but there are several pain points. Pain point 1, because the volume of the existing lock cylinder is limited, the volume space of the lock cylinder is also limited, so that the number of marbles or plates that can be arranged is limited, that is, the number of passwords for the lock cylinder Less pain points that lead to high mutual opening rate; pain point 2, the lock cylinder requires a specially matched lock structure to achieve uninterrupted rotation to open those locks that need to be turned for several weeks; pain point 3, the lock cylinder can only be unlocked or locked in one direction ; Therefore, the application scenarios of such a lock cylinder are limited

[0007] Patent CN201710167387.3 provides a lock core and an automatic clutch key that prevents technical opening and can automatically reset the lock dial. Although a return spring is added to the lock dial to realize that the lock dial can be quickly activated when the lock is unlocked. Automatic reset, but it also adds a pain point. Pain point 1 restricts the lock cylinder from being able to rotate uninterruptedly to open those locks that need to be rotated for several weeks. If it is forced to rotate, it will destroy the return spring; pain point 2, because the existing lock The limited volume of the core leads to the limited volume space of the lock cylinder, so that the number of marbles or sheets that can be arranged is limited, that is, the small number of codes of the lock cylinder leads to the pain point of high mutual opening rate; pain point 3, the lock cylinder is also only Can be unlocked or locked in one direction; therefore, the application scenarios of such a lock cylinder are also limited
