Abstract

The invention relates to an electromagnetic unlocking device. The electromagnetic unlocking device comprises a circular ring columnar coil winding component (3). The inner ring wall of the coil winding component (3) is axially provided with at least one guide block (31). An inner ring of the coil winding component (3) is provided with an armature (4) and a rotor (5), wherein the armature (4) can axially move along the coil winding component (3), and the rotor (5) makes contact with the lower portion of the armature (4) and can both axially move and circumferentially rotate along the coil winding component (3). The lower end of the rotor (5) is provided with a pin shaft (57) for achieving locking or unlocking with the outside world. A spring (6) is placed between the rotor (5) and a shell. The upper end of the outer wall of the rotor (5) is provided with at least one deep groove and at least one shallow groove. According to the electromagnetic unlocking device, the unlocking or locking state can be kept under the power outage condition.

Description

technical field [0001] The invention relates to the technical field of mechanical connectors, in particular to an electromagnetic unlocking device. Background technique [0002] At present, the commonly used electromagnetic unlocking device is mainly composed of coil winding parts, armature, back cover, spring, pin and shell. , the spring is placed between the rear end of the armature and the back cover, and the back cover is fixedly connected with the shell. When the coil winding is energized, an electromagnetic force is generated to retract the armature and pin against the spring pressure, and the electromagnetic unlocking device is in an unlocked state; when the coil winding is powered off, the spring pressure makes the armature and pin stretch out, and the electromagnetic unlocking device is in a locked state . In order to keep the electromagnetic unlocking device in the unlocked state, the coil winding must always be kept energized, so that the coil winding kept in th...
