Anti-theft concealed fingerprint identification device

Abstract

The invention discloses an anti-theft concealed fingerprint identification device, which comprises a door handle and a fingerprint device. The door handle is provided with the fingerprint device; thedoor handle is internally provided with a cavity; the door handle is provided with an opening which is communicated with the cavity; the fingerprint device is composed of a fingerprint sensor, a lifting device, a transmission device, a protection device and a wiping device; the protection device is disposed at the opening; the wiping device is disposed above the protection device; the side surfaceof the wiping device is provided with the fingerprint sensor; the fingerprint sensor is connected with the lifting device; the bottom part of the lifting device is in transmission connection with theprotection device through the transmission device; and the lifting device is composed of a spring, a turntable, a nut, a screw, a guide rail and a wire wheel. The anti-theft concealed fingerprint identification device has the beneficial effects that electricity is not needed while protection is obtained, thereby being energy saving and environmental friendly; a user can adopt a correct gesture for verification, thereby improving the verification correctness and the efficiency; the fingerprint theft possibility is avoided, thereby improving the safety; and a sponge wheel can be recycled, thereby achieving better cleaning effects.

Description

technical field [0001] The invention relates to the technical field of fingerprints, in particular to an anti-theft hidden fingerprint identification device. Background technique [0002] Fingerprint recognition technology is widely used, and fingerprint recognition technology can be seen in access control and time attendance systems. [0003] At present, fingerprint door locks should be widely used. In order to avoid damage, the patent application No. 201820403840.6 proposes that the fingerprint sensor can be concealed by rotation to avoid damage, but this design needs to be rotated by a motor during use, which will accelerate the consumption of batteries. Power, reduce the length of power consumption. When in use, the fingerprint will be printed on the fingerprint sensor. If it is not erased in time, it is easy for someone to steal the fingerprint and copy it, which reduces the safety factor. When the fingerprint is pressed, the angle deviates from the original fingerprint...

[0003] At present, fingerprint door locks should be widely used. In order to avoid damage, the patent application No. 201820403840.6 proposes that the fingerprint sensor can be concealed by rotation to avoid damage, but this design needs to be rotated by a motor during use, which will accelerate the consumption of batteries. Power, reduce the length of power consumption. When in use, the fingerprint will be printed on the fingerprint sensor. If it is not erased in time, it is easy for someone to steal the fingerprint and copy it, which reduces the safety factor. When the fingerprint is pressed, the angle deviates from the original fingerprint , the verification time will be extended, which may lead to failure of verification and misjudgment
