Abstract

The invention discloses a fireproof door magnet switch. The fireproof door magnet switch comprises a door magnet body assembly, a right door magnet lock body assembly, a left door magnet lock body assembly, a body drive motor, a body main gear, a body transmission gear, a radial bevel gear, an axial bevel gear, a transmission hexagon, a transmission connecting rod, a lock catch, spring bolts, driving cams, driving cranks, driven cams, driven cranks, pushing sliding blocks, following wheels, lock body motors, gear supporting shafts, lock body main gears, gear locking screws, lock body driven gears and gear transmission shafts. The door magnet body assembly is fixed to a fireproof door frame. The right door magnet lock body assembly and the left door magnet lock body assembly are symmetrically fixed to a door leaf. In the left door magnet lock body assembly and the right door magnet lock body assembly, the lock body motors are used for driving matched transmission of gears and crank cammechanisms, the spring bolts fixed in the pushing sliding blocks are driven to move front and back to be matched with the lock catch in the door magnet body assembly fixed to the fireproof door frame,and door leaf locking, opening and closing are achieved.

Description

technical field [0001] The invention relates to an electromagnetic switch device, in particular to a magnetic switch for a fire door. Background technique [0002] The traditional fire door magnetic switch is mainly composed of a switch and a magnet. The magnet is encapsulated in the magnetic housing to generate a constant magnetic force. The normally open reed switch installed inside and the distance between the door leaf and the door frame , to realize the opening and closing of the fire door. Once the electromagnetic failure or electrical connection failure occurs, the door magnetic switch will be unusable, resulting in failure of the fire door switch structure. Moreover, many fixing screws of the existing door magnetic switch leak, and the anti-theft effect is not good. Contents of the invention [0003] Aiming at the above problems, the present invention provides a magnetic door switch for fire doors, which drives the front and rear movement of the lock tongue throu...
