Hard-wired emergency lock for smart locks without carrying keys

Abstract

The invention discloses an intelligent lock hard-connected emergency lock allowing users not to carry keys. The emergency lock comprises an inner lock plate, an outer lock plate, a fingerprint coded lock device, a mechanical coded lock, an inner handle of a door and an outer handle of the door. The fingerprint coded lock device comprises a coded lock motor. The fingerprint coded lock device and the mechanical coded lock are connected with the coded lock motor through a clutch. The coded lock motor is connected with the inner handle and the outer handle of the door. The coded lock motor and the mechanical coded lock are connected with a lock drag-link mechanism. According to the fingerprint coded lock, the clutch is connected with the fingerprint coded lock device and the mechanical coded lock, the coded lock motor is connected with the inner handle and the outer handle of the door, meanwhile, the coded lock motor and the mechanical coded lock are connected to the clutch, the inner handle and the outer handle are adopted for being connected with the lock drag-link mechanism, and the inner handle or the outer handle is rotated finally. After the emergency lock is used, only fingerprint codes or mechanical codes are needed for unlocking, the keys do not need to be carried, and use is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of emergency unlocking of fingerprint coded locks, in particular to hard-connected emergency locks for smart locks that do not need to carry keys. Background technique [0002] Fingerprint locks are intelligent locks, which are the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The characteristics of fingerprints have become the most important evidence for identification and are widely used in public security criminal investigation and judicial fields. Fingerprint authentication has the characteristics of convenience, speed and accuracy. With the popularization of technology and the development of smart homes, more and more people have begun to choose fingerprint locks. [0003] But no matter how the fingerprint lock is developed and applied, it must have a mechanical key. This is a backup way to open the door, just l...

Problems solved by technology

[0003] But no matter how the fingerprint lock is developed and applied, it must have a mechanical key. This is a backup way to open the door, just like airplanes and cars, although they have automatic control, they still retain the manual control part, but for most people In other words, especially for people who often use fingerprint locks, they rarely take the initiative to bring keys, that is to say, fingerprint combination locks with mechanical keys are not practical as emergency locks.
