Split fingerprint lock

Abstract

The invention provides a split type fingerprint lock. The split type fingerprint lock comprises a lock body end, a handheld end unlocking device and an emergency unlocking key, wherein the lock body end comprises a lock body upper cover, a lock body lower cover, a part fixing part, a dynamic connecting mechanism, an electromagnetic control mechanism, an emergency lock and a fingerprint processing chip; the dynamic connecting mechanism is arranged inside a handheld end insertion hole of the lock body end; the dynamic connecting mechanism is connected with the electromagnetic control mechanism; an emergency dynamic connecting rod is arranged inside the lock body; one end of the emergency dynamic connecting rod is connected with the emergency lock; one end of the emergency dynamic connecting rod is connected with the electromagnetic control mechanism; during emergency unlocking, the dynamic connecting rod pulls an electromagnetic core to leave a square groove of a second dynamic connecting piece, so as to remove the limiting function; then, the dynamic connecting mechanism is rotated to be unlocked. According to the invention, in case of emergency unlocking, the combined action of the emergency lock and the dynamic connecting mechanism is played, so that emergency unlocking is realized under the cooperation of the emergency lock and the dynamic connecting mechanism; the safety factor of the fingerprint locks is improved; when multiple locked devices are managed in large quantities, the unique split-type design enables the cost of the finger print locks to be greatly reduced, the use efficiency to be improved, the maintenance cost to be decreased and the safety factor of the locked devices to be improved.

Description

technical field [0001] The invention belongs to the field of mechanical structure of locks, in particular to a split fingerprint lock. Background technique [0002] The existing fingerprint locks in the market are integrated with the fingerprint sensor on the lock body, which cannot overcome the damage to the fingerprint sensor caused by the influence of extreme temperature and the erosion of the harsh environment, and cannot escape the malicious damage to the sensor and circuit board by others. Risk, once the fingerprint sensor is damaged, the entire lock will have to be replaced, and the security is not high, which greatly affects the quality and life of the fingerprint lock. [0003] At present, the locks on the market use the emergency key to unlock independently for emergency unlocking. The emergency unlocking mechanism and the normal unlocking mechanism are used separately to unlock. When emergency unlocking is required, only the emergency unlocking key is needed to un...

Problems solved by technology

[0002] The existing fingerprint locks in the market are integrated with the fingerprint sensor on the lock body, which cannot overcome the damage to the fingerprint sensor caused by the influence of extreme temperature and the erosion of the harsh environment, and cannot escape the malicious damage to the sensor and circuit board by others. Risk, once the fingerprint sensor is damaged, the entire lock must be replaced, and the security is not high, which greatly affects the quality and life of the fingerprint lock

[0003] At present, the locks on the market use the emergency key to unlock independently for emergency unlocking. The emergency unlocking mechanism and the normal unlocking mechanism are used separately to unlock. When emergency unlocking is required, only the emergency unlocking key is needed to unlock the lock. Or any lock control mechanism of the normal unlocking mechanism can pry open the lock, and the safety factor of the lock is not high
