永电磁锁

Permanent electromagnetic lock

Abstract

永电磁锁有框和与框配合的扇,框和扇分别设有永磁铁和电磁铁,电磁铁的铁芯端部与永磁铁磁极对应。利用永磁铁对电磁铁的铁芯的吸合,锁闭框和扇,而不使用电能。将电磁铁简短的通电,电磁铁的磁场方向与永磁铁的磁场方向相反,产生排斥力解除磁力锁闭状态。最好永磁铁磁极端连有铁延伸块,电磁铁的铁芯端部与永磁铁磁极端的铁延伸块对应吸合。永磁铁或其磁极端连有铁延伸块与框或扇松弛连接,或永磁铁或其磁极端连有铁延伸块与框或扇之间夹有软垫或弹性垫,来保证吸合件之间的充分接触,增强吸合力。
A permanent electromagnetic lock is provided with a frame and a fan matched with the frame; the frame and the fan are respectively provided with a permanent magnet and an electric magnet. The iron core end part of the electric magnet is corresponding to the pole of the permanent magnet. The frame and the fan are locked by utilizing the suction of the permanent magnet to the electric magnet without using electricity. The electric magnet is briefly electrified; the direction of the magnetic field of the electric magnet is opposite to the direction of the magnetic field of the permanent magnet to generate a repulsive force and release the closing state of a magnetic lock. The pole end of the permanent magnet is better to be connected with an iron extending block; the iron core end part of the electric magnet is correspondingly sucked with the iron extending block at the pole end of the permanent magnet. The permanent magnet or the pole end thereof is connected with the iron extending block which is loosely connected with the frame or the fan or the permanent magnet or the pole end thereof is connected with the iron extending block; a soft cushion or an elastic cushion is clamped between the permanent magnet and the frame or the fan or between the pole end and the frame or the fan so as to ensure the suction pieces to be fully contacted and enhance the suction force.
