Description

technical field [0001] The invention belongs to the technical field of locks, and relates to a combination device and a use method of a resilient magnetic drawer lock and a key assembly. Background technique [0002] The drawer lock usually includes a lock head and a lock seat for matching use. The lock head is installed on the drawer plate, and the magnetic force of the key is used to drive the lock tongue in the lock head to move, so that the lock tongue is inserted into the lock seat or separated from the lock seat, thereby Realize the opening and closing of the drawer lock. For example, the patent name is "A Bolt Type Safety Magnetic Cabinet Lock and Its Application Method", and the patent application number is 201710573682.9 Chinese invention patent, which discloses a drawer lock that cooperates with a magnetic key and a magnetic lock head. By moving the auxiliary magnetic block on the key, the lock block on the lock head is driven to move, thereby driving the lock rod...

AI Technical Summary

Problems solved by technology

[0003] 1. Regardless of opening or closing the lock head, it is necessary to move the auxiliary magnetic block on the key to drive the lock lever to move. Although it can prevent the lock lever from affecting the user, it cannot automatically reset the lock lever. It does not have an automatic locking function and is safe. Hidden danger

[0004] 2. The auxiliary magnetic block on the key will drive the lock block to move under normal circumstances, but if the lock rod and the lock slot are misaligned, the movement of the auxiliary magnetic block on the key will not drive the lock block to move, which poses a safety hazard. Unable to judge the state of the lock lever, and unable to feed back the state of the lock lever to the key
