Embodiment
[0042] Under normal conditions, the electromagnetic door suction (not shown in the figure) is energized to adsorb the normally open fire door 8 on the wall and keep it open; 1 Relatively fixed to form a complete and continuous track;
[0043] When a fire alarm occurs, the power supply of the electromagnet suction cup 2 and the suction cup 5 is disconnected under the control of the fire protection system; the electromagnet suction cup 2 that loses power supply is no longer in a fixed state with the suction cup 5;
[0044] After losing the fixing function of the electromagnet suction cup 2 and the suction cup 5, only one end of the movable rail 9 is connected with the second fixed rail 11 by hinges, and automatically falls under the action of its own gravity, disconnects from the connection with the first fixed rail 1, and leaves the fireproof door closing area;
[0045] The fire door 8 loses the adsorption and fixing effect of the electromagnetic door suction, and starts to cl...
Embodiment 2
[0047] In the normal state, the electromagnetic door suction (not shown in the figure) is energized to adsorb the normally open fire door 8 on the wall and keep it open; In the locked position, the movable rail 9 and the first fixed rail 1 are relatively fixed to form a complete and continuous rail; at the same time, the striker 4 is pressed to compress the spring 3 to a certain extent.
[0048] In the event of a fire, the power supply of the electromagnet suction cup and the suction cup shall be disconnected under the control of the fire protection system; the electromagnet suction cup without power supply is no longer in a fixed state with the suction cup, and the spring in the compressed state pushes the striker to push the lock tongue out and lock. area;
[0049] After losing the fixing function of the electromagnet suction cup 2 and the suction disk 5, the locking tongue 6 also loses the fixing function, and only one end of the movable rail 9 is connected with the second ...
