Abstract
Disclosed is an electric control lock which relates to lever electric control door lock which comprises a lock body, a lock tongue, an electromagnetic coil, an armature valve core, a spring and a lever; wherein, the electromagnetic coil is arranged on the lock body, the armature valve core is arranged in the electromagnetic coil, the spring is arranged on the periphery of the lock tongue, the rear end of the lever is fixed on the lock body, and the lever is arranged between the armature valve core and the lock tongue. When the electric control lock is electrified, small current enables the electromagnetic coil to generate magnetic field, so as to enable the armature valve core to move forwards and enable the lock tongue to extend out of the lock body, and then the door is locked. When the power supply is cut off, the magnetic field disappears, and the lock tongue moves backwards due to the tension force of the spring, so the armature valve core is enabled to move backwards synchronously and move to the original position. The lock tongue is in the same level with the lock body, and the door is unlocked. As small current enables the electromagnetic coil to generate electromagnetic induction, so as to drive the armature valve core to move and drive the lock tongue to move back forwards and backwards, the electric energy is saved due to low electric consumption operation. Small current also can avoid the metal collision sound and prolong the service life of door lock.
