Fingerprint lock

Abstract

The invention discloses a fingerprint lock. The fingerprint lock comprises a lock body, a front cover plate is installed at the front side of the lock body, a lock core chamber is formed in the middleof the lock body, and a rear cover plate is installed at the rear side of the lock body. The fingerprint lock is scientific, reasonable and safe and convenient to use; a dustproof cover, non-slip sponge ribs, a fixing ring, fixing springs and a fixing rubber ring are arranged; through the dustproof cover, the situation that dust in air enters the fingerprint lock through a lock hole and the connection of devices in the fingerprint lock fails can be effectively prevented, and the service life of the fingerprint lock can be effectively prolonged; through the fixing ring, the dustproof cover isconveniently fixed and is prevented from slipping in the dustproof process; a moisture-proof chamber, a drying agent and drying holes are arranged; through the drying agent, the moisture in the air inthe fingerprint lock can be absorbed and effectively prevented from causing corrosion and rust on the precise devicse in the fingerprint lock, and the service life of the fingerprint lock can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of fingerprint locks, in particular to a fingerprint lock. Background technique [0002] Fingerprint lock is a kind of intelligent lock that uses the fingerprint of human finger part as the identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint lock is generally composed of electronic identification and control and mechanical linkage. The system consists of two parts. The uniqueness and non-reproducibility of living fingerprints determine that fingerprint locks are the safest locks among all locks at present. In the prior art, the use of fingerprint locks has the following disadvantages: when in use, the internal fingerprint lock The fingerprint reader will be exposed to the external environment, and more dust will be accumulated, and the fingerprint reader will be artific...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a fingerprint lock, which can effectively solve the problem that the fingerprint reader inside the fingerprint lock will be exposed to the external environment and accumulate a lot of dust when used in the above background technology, and the fingerprint reader will be artificially damaged. malicious damage, reducing the service life of the fingerprint lock; when in use, due to the lock hole, the dust from the outside will enter the lock through the lock hole, resulting in a lot of dust on the surface of the internal precision mechanical parts, which cannot be cleaned. If things go on like this, it will lead to Damage to the fingerprint lock; when in use, if the air humidity is too high, the moisture in the air will cause the mechanical parts inside the fingerprint lock to rust and corrode and cannot be used, reducing the service life of the fingerprint lock; when in use, closing and opening the door During the process, there will be a collision between the door frame and the door to generate vibration. Since the interior of the fingerprint lock is a precision device, a small vibration may affect the normal use of the fingerprint lock and reduce the service life of the fingerprint lock; when the power is turned off, The fingerprint lock will not work, you need to temporarily purchase a spare power supply and install the power supply before you can continue to use the fingerprint lock; moreover, the surface of the display screen will accumulate a lot of dust, which is difficult to clean, so the problem
