It is a fireproof partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. Fire doors are specifically used to isolate fire sources in house buildings and play a huge role in fire fighting. Once a fire occurs, people can get a chance to escape through fire doors. For example, a sealing structure of a fire door with Chinese patent application number CN202320557998.X includes a fireproof door frame, one side of the interior of the fireproof door frame is rotatably connected to a door shaft, and the fireproof door frame is rotatably connected to a fireproof door panel through the door shaft, the bottom and top of the fireproof door frame are both provided with grooves, and a fire-expanding fireproof strip that expands when exposed to fire is fixedly connected in the groove, and a magnetic sheet is fixedly connected to the bottom of the rear side of the fireproof door panel. The advantages of the utility model are: by arranging fire-expanding fireproof strips at the top and bottom of the fireproof door frame, under normal circumstances, the fireproof strips that expand when exposed to fire shrink in the grooves to avoid the possibility of pedestrians rubbing off the fireproof strips when passing by, and a gap is created between the fireproof door panel and the fireproof door frame, so that the fireproof door panel can rotate smoothly and a small amount of air can circulate; when a fire occurs, the fireproof strips that expand when exposed to fire expand due to heat and block and close the gap between the fireproof door panel and the fireproof door frame, thereby improving the sealing of the fireproof door in the event of fire.
