Description

Technical Field

[0001] The utility model relates to an electromagnetic lock with high waterproof and dustproof performance and high safety, belonging to the technical field of electromagnetic locks. Background Technique

[0002] The design of the electromagnetic lock is the same as that of the electromagnet. It uses the principle of electro-magnetic generation. When an electric current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly hold the adsorption iron plate to achieve the effect of locking the door. As long as there is a small current, the electromagnetic lock will generate a great magnetic force. After the access control system that controls the power supply of the electromagnetic lock identifies the personnel correctly, the power supply is cut off, and the electromagnetic lock loses its suction force, then the door can be opened. The electromagnetic lock is mainly applicable to the interlocking parts that need to be locked on the front and rear cabinet doors of indoor high-voltage switchgear to prevent misoperation. It is an indispensable locking device for power generation and power supply departments. In addition, to meet the needs of integrated automation substations, some electromagnetic locks have also added auxiliary contacts inside the lock, which can provide a pair of corresponding switch contacts for users at the closing and opening positions of the lock, facilitating the mutual interlocking of user locks and integrated automation sampling, avoiding the empty stroke, and is an ideal locking device for modern substation equipment.

[0003] Chinese Patent (Publication No.: CN 217481009 U3) discloses a double-locking structure of a high-safety electromagnetic lock, including an electromagnetic rod and a lock fastener connected through an electromagnetic lock head; a lock slot is opened on one side of the lock fastener facing the electromagnetic rod, the front end of the electromagnetic lock head is a semi-cylindrical structure, a second card slot is opened on the front-end plane of the electromagnetic lock head, a second reset slot is opened at a position corresponding to the second card slot inside the lock slot, a magnetic attraction block is connected in the second reset slot through a plurality of reset springs, and a card block is arranged at the lower end of the magnetic attraction block; a first card slot is opened on the upper part of a section of the electromagnetic lock head close to the electromagnetic rod, symmetrically distributed first reset slots are opened on the inner side wall of the lock slot at positions corresponding to the first card slot, and a movable block adapted to the first card slot is movably connected in the first reset slot through a spring shaft;

[0004] This utility model can double-lock the electromagnetic lock, avoid the phenomenon of the electromagnetic rod and the lock fastener being disengaged, improve the use stability of the electromagnetic lock, and enhance the locking effect of the electromagnetic lock.
