Emergency mechanical lock device for fingerprint lock and fingerprint lock

Abstract

The embodiment of the invention discloses an emergency mechanical lock device for a fingerprint lock and a fingerprint lock. A lock cylinder connecting piece is disposed between a mechanical lock cylinder and a reduction gear box, so that the reduction gear box is separated from the mechanical lock cylinder when unlocking is performed through a normal fingerprint, and a lock tongue assembly is notsubjected to limitation and influence of the mechanical lock cylinder. In an emergency, when a mechanical key is used to unlock the mechanical lock cylinder, the lock cylinder connecting piece is inserted in a driven reduction gear of the reduction gear box under the action of thrust, and the lock tongue assembly is driven to complete emergency unlocking operations. The whole process is very easyto operate, the whole structure is simple in design, the number of parts is small, and the reliability of the emergency mechanical lock device is greatly improved. Meanwhile, when the lock cylinder and the lock cylinder connecting piece are made into two parts that are independent and can be connected with each other, different types and levels of lock cylinders can be selected according to clients' requirements for mechanical lock cylinder kind and safety level, the end of the lock cylinder is slightly modified, and the design freedom is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint locks, in particular to an emergency mechanical lock device for a fingerprint lock and a fingerprint lock. Background technique [0002] Fingerprint lock is a security product produced through the precise combination of electronic components and mechanical components. Its most essential features are nothing more than three aspects of safety, convenience and fashion. But any electronic part has the possibility of error. Relatively speaking, the mechanical part is much more stable. Keeping the mechanical key of the lock as a backup method of opening the door can open the door in time and facilitate maintenance when there is a problem with the electronic part of the door lock. If a fire or other emergency occurs, or the thief damages the electronic part of the lock because he did not pry open the lock, it cannot be unlocked by fingerprints. This often happens, so fingerprint locks are usually des...

AI Technical Summary

Problems solved by technology

[0003] The emergency mechanical lock device of the existing fingerprint lock is often designed too complicated, and the two cannot be well combined, resulting in the emergency mechanical lock device being unable to quickly and effectively open the lock in an emergency

In order to realize that the emergency mechanical lock will not interfere with the unlocking process when the fingerprint is unlocked, so that the two operate independently of each other and do not affect each other, this leads to an excessively large volume of the emergency mechanical lock device and increases the cost.
