Multi-lock-cylinder linkage electronic lock

Abstract

The invention discloses a multi-lock-cylinder linkage electronic lock. The multi-lock-cylinder linkage electronic lock comprises an electronic drive mechanism, a linkage mechanism, a main linkage lockcylinder and an auxiliary linkage lock cylinder. The linkage mechanism comprises a main lock linkage plate, an auxiliary lock linkage plate and an ascending and descending linkage rod. The main linkage lock cylinder comprises a first horizontal movement spring bolt fixedly provided with a first horizontal movement guide column. A first horizontal movement sliding groove is obliquely formed in themain lock linkage plate, and the main lock linkage plate has the elastic potential energy to move to the locking end of the first horizontal movement spring bolt. The auxiliary linkage lock cylindercomprises a second horizontal movement spring bolt fixedly provided with a second horizontal movement guide column, a second horizontal movement sliding groove is obliquely formed in the auxiliary lock linkage plate, and the second horizontal movement guide column is located in the second horizontal movement sliding groove. The multi-lock-cylinder linkage electronic lock is provided with a simplelinkage structure, and when an inner chip of the electronic lock breaks down, a mechanical key can be used for unlocking, and locking can be automatically conducted.

Description

technical field [0001] The invention relates to the technical field of anti-theft door locks, in particular to a multi-cylinder linkage electronic lock. Background technique [0002] In order to improve the security of the anti-theft door, most of the anti-theft door locks with high technical level have a structure of multiple lock cylinders, so as to improve the difficulty of brute force cracking of the lockset; while most of the multi-lock cylinder linkage mechanisms in the prior art have a relatively complicated structure, Therefore, the processing complexity and cost of the lock are increased, and the reliability of the lock is reduced. [0003] In addition, with the continuous improvement of users' requirements for the convenience of locks, more and more anti-theft door locks have begun to adopt fingerprint unlocking or password unlocking technology, and at the same time set up mechanical key unlocking holes; but conventional mechanical key unlocking holes are mainly us...

AI Technical Summary

Problems solved by technology

[0002] In order to improve the security of the anti-theft door, most of the anti-theft door locks with high technical level have a structure of multiple lock cylinders, so as to improve the difficulty of brute force cracking of the lockset; while most of the multi-lock cylinder linkage mechanisms in the prior art have a relatively complicated structure, Thereby increasing the processing complexity and cost of the lock, and reducing the reliability of the lock

[0003] In addition, with the continuous improvement of users' requirements for the convenience of locks, more and more anti-theft door locks have begun to adopt fingerprint unlocking or password unlocking technology, and at the same time set up mechanical key unlocking holes; but conventional mechanical key unlocking holes are mainly used To enable users who have no fingerprints or have forgotten the unlock password to unlock the lock, the mechanical key is usually only used for identity verification, that is, the mechanical key skips the identity verification and directly starts the unlocking drive device, and because electronic products inevitably There will be reliability problems. Once the internal chip of the electronic lock fails, the mechanical key will not be able to open it.

[0004] Again, the conventional multi-cylinder linkage lockset requires active operation when it is unlocked and locked. protruding out to match the lock hole on the door frame, the above-mentioned multi-lock cylinder linkage lockset is extremely inconvenient to use, which affects the user's experience
