DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a single-opening steel fire door with a fire door mirror structure, including a fire door frame 1 and a fire door panel 2 movably hinged in the fire door frame 1, the inner side of the fire door frame 1 is fixedly connected with a clamping inner frame 3, the inner side of the fire door panel 2 is provided with a snap-fit ​​groove 4, and a sealing component 5 is fixedly installed between the fire door frame 1 and the fire door panel 2.

[0024] By providing a sealing component 5 located on the fire door frame 1 and the fire door panel 2, when the fire door frame 1 is closed, the fire door panel 2 and the fire door frame 1 are closed and the sealing component 5 is pressed to improve the sealing between the fire door frame 1 and the fire door panel 2, thereby effectively preventing fire and smoke from escaping from the gap between the fire door panel 2 and the fire door frame 1, thereby improving the fireproof performance. At the same time, the different materials inside the fire door panel 2 can reduce the weight of the fire door panel 2 while ensuring its fireproof and heat-insulating effect, making it easier to open and close.

[0025] like Figures 2 to 4 As shown, the sealing assembly 5 includes a limiting convex edge 51, a sealing strip 52, a pressing convex strip 53, a side wear-resistant sealing pad 54, a fixed block 55 and a movable rubber sheet 56. The limiting convex edge 51 is fixedly connected to the side of the pressing inner frame 3 close to the fireproof door panel 2, the sealing strip 52 is fixedly connected to the inner side of the limiting convex edge 51, the pressing convex strip 53 is fixedly installed on the inner side of the fireproof door panel 2, the side wear-resistant sealing pad 54 is movably clamped to the inner side of the clamping groove 4, the fixed block 55 is fixedly connected to the bottom of the fireproof door panel 2, and the movable rubber sheet 56 is fixedly connected to the bottom of the fixed block 55.

[0026] When the fireproof door panel 2 is closed, the pressing convex strip 53 located on the inner side of the fireproof door panel 2 is inserted into the sealing strip 52 on the inner side of the limiting convex edge 51, and the pressing convex strip 53 squeezes the sealing strip 52 to deform the sealing strip 52 and press against the pressing convex strip 53 and the fireproof door panel 2. At the same time, the side wear-resistant sealing pad 54 is deformed by force to make it fit the inner side of the fireproof door frame 1. The fireproof door panel 2 is movable to move the movable rubber sheet 56 to fit the ground to ensure the sealing effect between the fireproof door frame 1 and the fireproof door panel 2, so as to improve the effect of blocking fire and smoke.

[0027] like Figure 5 As shown, the fireproof door panel 2 includes an outer substrate 21, a first filling layer 22, a second filling layer 23, a polyurethane foam filler 24 and a fireproof coating 25. The interior of the outer substrate 21 is hollow, the first filling layer 22, the second filling layer 23 and the polyurethane foam filler 24 are filled in the interior of the outer substrate 21, the second filling layer 23 is located on the outside of the polyurethane foam filler 24, the first filling layer 22 is located on the outside of the second filling layer 23, and the outside of the polyurethane foam filler 24 is coated with a fireproof coating 25.

[0028] By arranging the first filling layer 22, the second filling layer 23, and the polyurethane foam filler 24 inside the outer substrate 21 and cooperating with the fire-retardant coating 25 coated on the outside, the overall weight of the outer substrate 21 is reduced while ensuring the fireproof and heat-insulating effect, so as to facilitate switching.

[0029] like Figure 4 As shown, the pressing convex strip 53 is movably clamped on the inner side of the sealing strip 52 , and the side wear-resistant sealing pad 54 is attached to the inner side of the fireproof door frame 1 .

[0030] By pressing the convex strip 53 into the inner side of the sealing strip 52, the wear-resistant sealing pad 54 on the matching side is attached to the inner side of the fireproof door frame 1, so as to improve the sealing effect between the fireproof door frame 1 and the fireproof door panel 2, and effectively block the fire and smoke.

[0031] like Figure 3 As shown, the movable rubber sheets 56 are equidistantly arranged at the bottom of the fixed block 55 , and the movable rubber sheets 56 are in contact with the ground.

[0032] The movable rubber sheet 56 cooperates with the fixed block 55 to move and close along with the fireproof door panel 2, so that the movable rubber sheet 56 is in contact with the ground to ensure the sealing effect of the bottom of the fireproof door panel 2.

[0033] like Figure 3 As shown, the sealing strip 52, the side wear-resistant sealing pad 54 and the movable rubber sheet 56 are all made of silicone rubber.

[0034] The silicone rubber material has high heat resistance and chemical resistance to ensure its stable use.

[0035] like Figure 5 As shown, the first filling layer 22 is a rock wool board, the second filling layer 23 is an aluminum silicate wool material, and the fireproof coating 25 is a fluorocarbon coating.

[0036] The rock wool board has good fire resistance and heat insulation performance, and also has a certain sound insulation effect. The aluminum silicate wool has high fire resistance, heat insulation and oxidation resistance, which further ensures the strength of the outer substrate 21. The fluorocarbon coating is corrosion-resistant and high-temperature resistant, thereby ensuring the fireproof and heat-insulating performance of the fireproof door panel 2.

[0037] like Figure 1 As shown, a fireproof door mirror 6 is fixedly installed inside the fireproof door panel 2.

[0038] The fire door mirror 6 makes it easy to observe the internal situation of the fire door panel 2 through the outside of the fire door panel 2.

[0039] The following is a detailed description of the working principle of this single-opening steel fire door with a fire door mirror structure.

[0040] like Figures 1 to 5 As shown, when the fireproof door panel 2 is closed, the pressing convex strip 53 located on the inner side of the fireproof door panel 2 is inserted into the sealing strip 52 on the inner side of the limiting convex edge 51, and the pressing convex strip 53 squeezes the sealing strip 52 to deform and press against the pressing convex strip 53 and the fireproof door panel 2. At the same time, the side wear-resistant sealing pad 54 is deformed by force to make it fit the inner side of the fireproof door frame 1. The fireproof door panel 2 is used to move the movable rubber sheet 56 to fit the ground to block the fire and smoke. The first filling layer 22, the second filling layer 23, and the polyurethane foam filler 24 arranged inside the outer substrate 21 cooperate with the fireproof coating 25 coated on the outside to reduce its overall weight while ensuring the fireproof and heat-insulating effects of the outer substrate 21.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
