Description

Technical Field

[0001] The utility model relates to the technical field of fingerprint locks, in particular to a fingerprint lock with an emergency lock protective cover. Background Art

[0002] A fingerprint lock is an intelligent lock that uses the fingerprint of a human finger as an identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. A fingerprint lock is generally composed of two parts: electronic identification and control, and a mechanical linkage system. The uniqueness and non-replicability of living fingerprints determine that the fingerprint lock is the safest type of lock among all current locks. According to the publication number: CN209687048U, a fingerprint lock is disclosed, including a lock body, a handle and a lock core. The lock core includes a drive block, a baffle and a motor. The handle is rotatably arranged on the lock body, and a rotating part is arranged at one end of the handle passing through the lock body. The lock body is provided with an installation groove, and the drive block, the baffle and the motor are respectively arranged in the installation groove. The motor is connected to the baffle through a gear, and the motor drives the baffle to make a linear reciprocating motion in the horizontal direction. The two ends of the drive block are respectively in contact with the baffle and the rotating part. In this fingerprint lock, the motor of the lock core is connected to the blocking rod through gears. The motor drives the blocking rod to make linear reciprocating motion in the horizontal direction. When locked, the blocking rod blocks the driving block, and the driving block presses against the rotating part, so the handle cannot be turned and the lock tongue cannot be controlled to extend and retract. When unlocking, the fingerprint module recognizes the fingerprint and controls the motor of the lock core to drive the blocking rod to move. The driving block moves downward, so that the handle can rotate downward, thereby controlling the extension and retraction of the lock tongue. This fingerprint lock has a simple structure and high safety performance, but the above technology still has some defects. For example, the existing password lock does not have a keyhole protection structure. After long-term use, it is easy for external debris to accumulate inside the keyhole, resulting in poor use effect. The practicality is poor and needs to be improved. Utility Model Content
