Electromagnetic lock

Abstract

The invention provides an electromagnetic lock which comprises an installing base and a locking hook and further comprises a drive mechanism, a transmission mechanism, a lock-up mechanism and a locking mechanism. The drive mechanism is arranged in the installing base. The transmission mechanism is arranged in the installing base and connected with the drive mechanism. The lock-up mechanism is arranged in the installing base and connected with the transmission mechanism, and is suitable for rotating under the effect of external force. The lock-up mechanism is provided with a locking position for being locked with the locking hook under the effect of the locking hook, and an unlocking position for being unlocked with the locking hook under driving of the drive mechanism. The locking mechanism is arranged in the installing base and arranged between the lock-up mechanism and the side wall of the installing base. The locking mechanism is suitable for moving in a reciprocating manner in thedirection of being close to or away from the locking hook. The locking mechanism is provided with a first position for being connected with the lock-up mechanism in an abutting-against manner so as tostop the lock-up mechanism from rotating at the locking position, and a second position for being separated from the lock-up mechanism so that the lock-up mechanism can rotate normally. According tothe electromagnetic lock, the locking mechanism stops rotating of the lock-up mechanism, and therefore the electromagnetic lock will not be unlocked automatically when being affected by external vibration.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to an electromagnetic lock. Background technique [0002] The electromagnetic lock uses the principle of electricity to generate magnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force and tightly absorb the adsorption iron plate to achieve the effect of locking the door. Nowadays, electromagnetic locks are widely used in a wide range of applications. For example, lockers such as vending cabinets, display cabinets, storage cabinets, storage cabinets, and express cabinets are all equipped with electromagnetic locks. [0003] The existing electromagnetic lock includes a mount, a lock catch, a lock hook, a cam, a transmission assembly, an electromagnetic assembly and an iron core column. The lock catch, a cam, a transmission assembly, an electromagnetic assembly and an iron core column are all installed in the inst...
