[0002] Nowadays, in large public places such as shopping malls and shopping plazas, firefighting equipment is placed at fixed locations on each floor for fire safety. At the same time, for the beauty of public places, people will open fire doors at fixed locations and place firefighting equipment in the storage room behind the fire doors. In general, the fire doors are closed and fit with the surrounding walls, which not only saves space but also is good for appearance. In case of fire, the fire doors can be opened quickly to extinguish the fire.
[0003] The patent number CN220365492U in the prior art introduces a fireproof fire door, which relates to the technical field of fire doors. It includes a floor, a door frame is fixedly connected to the top of the floor, a door body is hinged on one side of the inner side of the door frame, a door handle is fixedly connected to the front and back sides of the door body, a door closer is fixedly connected to the back side of the door body, a fireproof mechanism is arranged inside the door body, and a blocking mechanism is arranged on one side of the bottom of the door body. When a person pulls the push-pull handle on one side, the spring telescopic rod is compressed, thereby driving the card block away from the first card slot, and then pressing the blocking handle downward, the energy compressed by the spring telescopic rod is released, so that the card block is engaged with the second card slot, which is convenient for fixing the position of the blocking block, reducing the possibility of the blocking block being moved by external force during blocking, thereby ensuring the fireproof performance of the fire door.
[0004] However, the patents in the prior art have the following disadvantages:
[0005] (1) When the patent in the prior art is in use, the fire door cannot be quickly closed and fixed, and the impact of heat waves may cause the fire door to open.
[0006] (2) When the patent in the prior art is in use, when a fire occurs, the smoke generated by the fire will penetrate through the gaps at the edges of the fire door, thereby causing damage. The blocking structure in the prior art requires manual control, is slow, and is prone to malfunction. Utility Model Content
