A fingerprint password lock device that can check the power at any time

Abstract

The invention relates to the technical field of intelligent fingerprint code locks, and discloses a fingerprint code lock device that can check the power at any time, including: a fingerprint lock body, a display is fixedly installed on the side of the fingerprint lock body, an upper end of the fingerprint lock body A fingerprint block is installed movable, the lower end of the fingerprint block is fixedly installed with a fixed rod, the lower end of the fixed rod is fixedly installed with a connecting block, the lower end of the connecting block is fixedly installed with a sleeve rod, the outer surface of the sleeve rod is sleeved with a pressure spring, and the pressure The lower end of the spring is fixedly connected with a stopper, and the end of the stopper away from the pressure spring is fixedly installed with a fixed frame. The fixed frame, the contact block and the compression spring can effectively protect the contact block and prevent the contact block from being in rigid contact with the sleeve rod for a long time, which will damage the contact block, so that the pressure spring and the contact block will be connected by the compression spring Rigid contact is transformed into elastic contact, which prolongs the service life of the contact block and saves cost.

Description

technical field [0001] The invention relates to the technical field of intelligent fingerprint coded locks, in particular to a fingerprint coded lock device capable of checking power at any time. Background technique [0002] Fingerprint intelligent combination lock is an intelligent lock, which is the crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The characteristics of fingerprints have become important evidence for identification and are widely used in public security criminal investigation and judicial fields. Fingerprint authentication is convenient and fast. The core components of fingerprint smart combination lock: motherboard, clutch, fingerprint collector, cryptographic technology, microprocessor (CPU), smart emergency key. [0003] At present, the existing smart fingerprint combination locks cannot provide users with information on power consumption, and cannot know how much power i...

Problems solved by technology

[0003] At present, the existing smart fingerprint combination locks cannot provide users with information on power consumption, and cannot know how much power is left in the combination lock. If charging, when people go home, press the combination lock, if the combination lock cannot be unlocked due to no electricity, people may not be able to enter their homes, which will bring more inconvenience to people's lives.
