Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a fireproof door with good sealing effect. Background Art

[0002] As the country carries out large-scale infrastructure construction, the demand for fire doors used in buildings is increasing. The thermal insulation and fireproof performance of existing steel insulated and sealed fire doors continues to improve to meet higher-end fire protection requirements.

[0003] The existing steel fire doors have better thermal insulation and fireproofing properties than ordinary fire doors, but their sealing effect is not as good as traditional fire doors. After the fire doors with low sealing are closed, the smoke generated by the fire will flow through the gaps between the fire doors. In addition, the existing steel fire doors are fireproofed by the high temperature resistance of their own rigid materials, which reduces the fireproofing effect and also causes damage to the installation parts of the fire doors.

[0004] As disclosed in Chinese patent CN218062090U, a steel fire door with good sealing effect is proposed. The door body is moved and driven to rotate by a damping shaft to close the door body. When the door body is closed, the second sealing strip installed around the door body can seal the door body and the door frame. At the same time, the sealing gasket in the installation groove box contacts the first sealing strip on the door body, and the sealing gasket is squeezed by the spring in the installation groove box so that the sealing gasket can fit tightly with the first sealing strip. When the door body is closed, the fire strip is supported by the buffer pad, and the door frame and the fireproof board installed on the outside of the installation groove box contact and close with the fire strip installed in the first installation groove.

[0005] However, in the prior art, when using fire doors for fire prevention, the high temperature generated by the fire will burn the door body, thereby increasing the temperature of the door body and causing damage to the door body. In addition, during a fire, the door body conducts heat due to the influence of the flame temperature, causing the temperature of the handle or door opening component to be too high, which can easily cause burns to firefighters, thereby having a certain impact on rescue.

[0006] For this reason, we urgently need to provide a fireproof door with good sealing effect. Utility Model Content
