Description

Technical Field

[0001] This utility model relates to the field of fire door technology, and in particular to an indoor fireproof door set. Background Technology

[0002] Doors are indispensable in any building. Fire doors, as a special type of door, not only have the functions of ordinary doors, but also have the special functions of fire prevention and smoke isolation. In the event of a fire, they play an important role in inhibiting the spread of fire and protecting people during evacuation.

[0003] Existing fire door installations require numerous auxiliary tools, are labor-intensive, and involve a complicated process. Dismantling them is also troublesome and makes replacement inconvenient, resulting in low work efficiency for staff. Furthermore, prolonged burning during a fire can cause the fire door surface to overheat, leading to rapid damage and reduced lifespan. Therefore, we propose an indoor fire-resistant door assembly.

Then, the upper door panel 3 and lower door panel 2 are placed into the door frame 1, aligning the two connecting posts 7 with adjacent fixing holes 8. Releasing the levers 9 allows the connecting posts 7 to insert into the fixing holes 8 under the return force of the first spring 5, thus improving the ease of assembly and disassembly of the door panel and door frame 1. Furthermore, if the door lock is damaged and the door cannot be opened, the bottom lever 9 can be pulled to remove the connecting posts 7 from the fixing holes 8. Pushing the lower door panel 2 upwards allows a person to exit, preventing them from being locked inside and improving the flexibility of the door set. In case of fire outside the door, the connecting head 1 can be pulled first. 6. The square rod 15 is pulled out from the inner cavity of the square groove 17, so that the rotating cylinder 13 can be rotated and the cover plate 12 can be moved away from the observation port 10, so that the user can easily observe the fire situation outside the door through the fireproof glass plate 11. When the user is observing the fire, the servo motor 22 can be started to drive the transmission gear 23 to rotate. The rotation of the transmission gear 23 drives the driven gear 24 to rotate. The rotation of the driven gear 24 drives the connecting pipe 21 to rotate, and drives the hollow cylinder 19 to swing back and forth, thereby driving the cleaning cloth 31 to automatically clean the fireproof glass plate 11 and improve the clarity of the fireproof glass plate 11. The water pump 27 can also be started to pump the water in the water tank 25 into the hollow cylinder 19 and spray it out through the nozzle 20, so as to extinguish the flames and wet the door panel at the same time, improve the fire resistance time of the door panel, and thus improve the user's safety.
