Description

Fire door for basement

Technical Field

The utility model relates to the technical field of doors and windows, in particular to a fire door for a basement.

Background

Fire doors refer to doors that meet fire stability, integrity, and thermal insulation requirements over a period of time. The fire-proof partition is arranged between fire-proof partitions, evacuation stairwells, vertical shafts and the like and has certain fire resistance. Besides the function of a common door, the fire door has the function of preventing fire from spreading and smoke from spreading, and can prevent fire from spreading within a certain time so as to ensure personnel to be evacuated.

Because of the gap between the fire door and the edge of the door frame, the smoke dust easily passes through the fire door, and the smoke dust is easily choked, syncoped and the like after being inhaled by people. In order to prevent excessive smoke from passing through the fire door, a new technical solution is required to solve the above problems.

In view of the above drawbacks, china's authorized utility model publication No.: CN211900326U discloses a fire door for a basement, which is provided with a door body, a door frame and a hinge, further makes the door body open or close more conveniently through the rotation of the hinge, and simultaneously, by arranging a first groove, a movable block, a sealing gasket and a first spring, further can be contacted with the sealing gasket when the door body is closed, so that the sealing gasket can move towards the direction inside the first groove, further can move the movable block towards the direction inside the first groove, so that the first spring can shrink, further can enable the movable block to have a trend of moving towards the outside of the first groove, so that the sealing gasket is always contacted with the door body, so that smoke is prevented from entering the basement, and meanwhile, when the door body is still not contacted with the sealing gasket after being closed, the nut, the sealing gasket and the second spring are arranged, further can move through rotating the nut, further can move the square block, so that the distance between the door body and the sealing gasket can be adjusted, further can enable the sealing gasket to always contact with the first groove, further can enable people to easily inhale smoke and dust to pass through the gap after the existing fire door, so that fire smoke can be easily inhaled by people after passing through the fire door, and fire door can be easily solved;

however, due to the structural design in the above-mentioned evidence, the fire-proof time of the fire door cannot meet higher requirements due to the limitation of materials, the fire door in the above-mentioned evidence is not used for a long time, the fire condition in the fire door cannot be observed, and the indoor personnel cannot conveniently judge the fire condition.

It should be noted that the information disclosed in the background section of the present utility model is only for enhancement of understanding of the general background of the present utility model and should not be taken as an admission or any form of suggestion that this information forms the prior art already known to those skilled in the art.
