Electronic lock and emergency unlocking method thereof

Abstract

The invention provides an electronic lock and an emergency unlocking method thereof and relates to the field of locks. The electronic lock is simple in structure and reliable in performance, emergency unlocking can be conducted on the locked lock, and meanwhile, illegal operation of emergency unlocking under the non-emergency situation also can be effectively prevented, so that unified management and monitoring of the lock is ensured. The electronic lock comprises a locking pin and a lock tongue base of a main lock body. An electronic locking mechanism comprises a blocking shaft and a locking block matched with the blocking shaft in a contact mode. The telescopic motion of the blocking shaft drives the locking block to lock or loosen the locking pin. An emergency unlocking mechanism comprises a sliding block and an anti-push mechanism. The sliding block is slidably arranged on the lock tongue base and provided with a locking block hole. The locking block is arranged in the locking block hole. When the locking block locks the locking pin, the sliding block can push the locking block to be away from the blocking shaft. The anti-push mechanism is arranged in a lock tongue base containing cavity and can lock the sliding block, limit sliding of the sliding block and release locking of the sliding block during emergency unlocking.

Description

technical field [0001] The invention relates to the field of locks, in particular to an electronic lock and an emergency unlocking method for the electronic lock. Background technique [0002] In order to prevent artificial opening operations, mechanical locks with high anti-theft level are used in electric power, communication and other departments to lock the doors of equipment rooms with a large number, wide distribution, harsh use environment and high safety requirements. However, traditional mechanical locks and unlocking devices usually adopt a contact connection structure, which has disadvantages such as low safety, high failure rate, large functional limitations, and easy matching of unlocking devices. [0003] For important places where the environment is harsh, the electronic door lock system will inevitably have electronic component failures, and the emergency unlocking mechanism is particularly important at this time. Quick and emergency unlocking is possible th...

However, after the existing emergency unlocking mechanism is often unlocked, the electronic lock is scrapped and cannot be used again, resulting in waste of resources

[0004] In addition, although electronic locks have the function of emergency unlocking, for example, the emergency unlocking mechanism in the invention patent with the publication number CN101109251A is easy to be reused after emergency unlocking, and the emergency unlocking key is often used to unlock the illegal operation problem.
