[0030] Working principle: When using the fire door, place the fire door body 1 inside the door frame 2. Since the fire door body 1 is mostly made of fire-resistant materials, it can block the flame to a certain extent. And the fire door body 1 and the door frame 2 are tightly connected, which can effectively prevent the spread of smoke. When using the sealing device 3, place the fire door body 1 inside the door frame 2, and then place the fire door body 1 inside the connecting groove 301. At the same time, squeeze the rubber frame 303 into the clamping groove 302. This can achieve sealing without causing wear to the rubber frame 303. When the fire door body 1 is placed on one side of the door frame 2, inflate the airbag 305. Since the airbag 305 is made of high-temperature resistant material, the gap between the fire door body 1 and the door frame 2 can be blocked by the airbag 305. This can improve the sealing effect to a certain extent and extend the service life to a certain extent. Among them, the limiting frame 304 is sleeved on the surface of the airbag 305. After the airbag 305 is inflated, the airbag 305 can be restricted to one side of the fire door body 1, which can well prevent the airbag 305 from moving randomly. The airbag 305 can be inflated well through the air pump 306 and the hose 307. Squeeze the rubber plug 310 into the airbag 305, so that the rubber plug 310 is away from the rubber ring 309. In this way, the air inside the airbag 305 can be released well. When using the limiting device 4, after placing the fire door body 1 inside the door frame 2, manually control the clamping strip 409 to slide into the rectangular groove 406, and then slide the clamping strip 409 into the clamping frame 401. Pull the clamping strip 409 in the direction close to the bottom of the rectangular groove 406 through the first spring 408, so as to well restrict the clamping strip 409 inside the clamping frame 401. After sliding the clamping strip 409 into the clamping frame 401, pass the clamping plate 402 through one side of the clamping frame 401, and pull the clamping plate 402 in the direction close to the clamping frame 401 through the second spring 404, so as to well restrict the clamping plate 402 on the top of the clamping strip 409. In this way, the fire door body 1 can be well restricted inside the door frame 2. Among them, manually control the sliding bar 411 to slide on the inner wall of the sliding groove 410, so as to well control the sliding of the clamping strip 409 on the inner wall of the rectangular groove 406.

[0031] It should be noted that all the damping rods in this case are telescopic dampers, which can absorb energy during the telescopic process.
