The invention relates to a door opener of anti-theft doors in case of power cut, comprising an electromagnetic plug, an unlocking plate, a magnetic seat and an electromagnetic lock. The magnetic seat arranged on an anti-theft door is connected with an unlocking eccentric disk, the unlocking eccentric disk is connected with the electromagnetic lock, the unlocking eccentric disk is provided with aneccentric hole, an upper lock plunger joint of an anti-theft lock under the magnetic seat is connected with the unlocking plate, the unlocking plate is connected with a bolt at the upper part of the anti-theft door, the unlocking plate is provided with an unlocking hole, the unlocking hole of the unlocking plate is squarely faced with the eccentric hole of the unlocking eccentric plate, an unlocking shaft of the electromagnetic plug on the unlocking plate is squarely faced with the eccentric hole of the unlocking eccentric plate. When power is cut off, the electromagnetic plug is disconnectedwith electricity, the unlocking shaft of the electromagnetic plug extends out to the unlocking hole and the eccentric hole, a lock core of the four-direction anti-theft lock is rotated by a key to drive the unlocking plate to move downwards, the unlocking eccentric plate and a cylinder-shaped magnet of a magnetic seat 4 are driven to rotate and form 90 degrees by the unlocking shaft, so that the magnetic force exerted on the door frame by the magnetic seat fixed on a movable door is eliminated and the anti-theft door is opened.
Description
Technical field [0001] The invention relates to an anti-theft door device, in particular to an anti-theft door opening device for power failure. Background technique [0002] Newly published Chinese patent: magnetic anti-theft door (patent number: ZL200820008172.3), when the door is to be opened, use the remote control to control the motor to drive the cylindrical magnet to rotate 90° clockwise, so that the S pole of the cylindrical magnet is in front, and the cylindrical magnet The N pole of the cylindrical magnet is at the back, and the magnetic field line of the cylindrical magnet is formed by the N pole of the cylindrical magnet through two magnetically conductive shells and the S pole of the cylindrical magnet to form an internal magnetic circuit, so that the magnetic field of the magnetically conductive block installed in the door frame When it is reduced to zero, the suction force between the magnetically conductive block and the two magnetically conductive shells is ...
