Description

Technical Field

[0001] The utility model mainly relates to the technical field of electromagnetic locks, in particular to an electromagnetic lock which is easy to repair. Background Art

[0002] Electromagnetic locks (also known as magnetic locks) are designed like electromagnets, utilizing the principle of electromagnetism. When current passes through a silicon steel plate, the electromagnetic lock generates a strong suction force, firmly adhering to the metal plate and effectively locking the door. Even a small current generates a strong magnetic force. Once the access control system that controls the electromagnetic lock's power supply correctly identifies the person, it powers off, and the electromagnetic lock loses its suction force, allowing the door to be opened. However, existing electromagnetic locks are inconvenient to repair, leading to an urgent need for a more easily repairable electromagnetic lock.

[0003] For example, patent application number 202321241588.0 discloses a waterproof and moisture-proof electromagnetic lock, including a mounting connection frame, the mounting connection frame is provided with a mounting connection hole, the mounting connection frame is connected to a waterproof and moisture-proof electromagnetic lock assembly, the waterproof and moisture-proof electromagnetic lock assembly includes a fixed mounting plate, a fixing bolt hole, an electromagnetic lock body, a ventilation and moisture-proof support ring plate, a dust-proof ventilation net, a motor support shaft, a ventilation and moisture-proof motor, a rotary ventilation and moisture-proof transmission shaft, and a rotary ventilation and moisture-proof fan blade. This utility model belongs to the technical field of electromagnetic locks. By installing the mounting connection frame and the fixed mounting plate, the waterproof and moisture-proof electromagnetic lock can be easily installed and fixed by the user, saving time and effort.
