Abstract: A magnetic lock is disclosed to include a latch for locking, a holder member supported on a spring and carrying an electromagnetic valve, which has a reciprocating rod fixedly mounted with a stop block for controlling the retraction of the latch, and an adjustment screw for controlling the holder member between a first position where the magnetic lock is locked when electrically connected and a second position where the magnetic lock is unlocked when electrically connected.

Abstract: An electromagnetic lock with a receiving space defined by a housing and a cover, comprising a lock catch, an solenoid valve, an adjusting unit, and a decoration plate all of which are received within the receiving space. The lock catch is pivotally coupled to a housing by a positioning shaft in match of a torque maintaining element. The solenoid valve includes a movable shaft and an end stop adapted to the lock. The position of the end stop is changeable when a voltage is applied to the solenoid valve, thereby determining whether or not the lock catch is engaged into the bottom of the housing. The adjusting unit includes an slide carriage to receive the solenoid valve. A restoring spring is interposed between the slide carriage and a fixing piece.

Abstract: A magnetic lock is disclosed to include a latch for locking, a movable holder member supported on a spring and carrying solenoid, which has a plunger and a stop block fastened to the plunger for controlling the retraction of the latch, and an adjustment device selectively positioned in one of two positioning grooves of different depths in a locating block and stopped at one end of the holder member against the spring for controlling the movable holder member between a first position where the magnetic lock is locked when electrically connected and a second position where the magnetic lock is unlocked when electrically connected.
