Description

Technical Field

[0001] The utility model relates to the technical field of magnetic locks, in particular to a remotely controlled magnetic lock. Background Art

[0002] The design of electromagnetic lock (or magnetic lock) is the same as that of electromagnet, which uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. As long as the current is small, the electromagnetic lock will generate a huge magnetic force. The access control system that controls the power supply of the electromagnetic lock will cut off the power after identifying the correct person, and the electromagnetic lock will lose its suction and the door can be opened.

[0003] Existing remote-controlled magnetic locks are generally locked by the adsorption between the electromagnetic block and the magnet when in use. The electromagnetic block and the magnet are usually fixed to the wall or door body by fixing bolts, so that when closing the door, the electromagnet and the iron block are adsorbed to complete the locking work. When disassembling for later maintenance, it is necessary to use disassembly tools for disassembly and maintenance, which is difficult to disassemble, increasing the difficulty and efficiency of maintenance. In addition, every time the door is closed, the magnetic attraction mechanism will collide with the iron block, which will cause damage to the internal components for a long time and reduce the locking effect. For this reason, we propose a remote-controlled magnetic lock. Utility Model Content
