[0032] Example 1

[0033] The assembled fire-fighting hidden door provided in this embodiment is used to solve the problems in the related art that the assembled fire-fighting hidden door has a small opening and closing angle, is easy to cause damage to fire-fighting equipment during use, and is not conducive to the safe evacuation of personnel in a fire.

[0034] See also Figure 1 , Figure 2 and Figure 4 , an assembled fire-fighting hidden door comprises a door frame 100 and a door leaf 200. The door leaf 200 is arranged in the door frame 100, one side of the door leaf 200 is hingedly mounted on the inner side of the door frame 100, and the side of the door leaf 200 away from the hinge can be relatively fixed to the door frame 100. An installation gap is left between the door leaf 200 and the door frame 100. The door frame 100 and the door leaf 200 are hinged by a chicken-beak hinge 290. The opening and closing angle between the door frame 100 and the door leaf 200 is set to α, satisfying: 0°≤α≤160°.

[0035] Specifically, when the door leaf 200 of the present embodiment is relatively fixed to the door frame 100, the prefabricated fire-fighting hidden door of the present embodiment remains closed; when the door leaf 200 is in contact with the door frame 100 and is relatively fixed, the door leaf 200 can be freely opened and closed to a suitable angle, so as to facilitate the use of the prefabricated fire-fighting hidden door of the present embodiment.

[0036] In emergency situations such as fire, the door leaf 200 of this embodiment improves the flexibility of the door leaf opening. The large opening and closing angle allows firefighters to enter and exit more easily when carrying equipment, avoiding damage to the finishing layer of the assembled fire-fighting hidden door. It has a good decorative appearance and can ensure the use requirements of fire-fighting equipment. When equipment or personnel pass through, they will not collide with the door leaf, thereby extending the service life of the utility model.

[0037] By using the chicken-bill hinge as a hinged part, the rotation between the door leaf and the door frame of this embodiment can be smooth and stable, and this embodiment is also flexible and durable during actual use, with strong load-bearing capacity, effectively ensuring the use requirements of fire-fighting equipment.

[0038] It is understandable that the fixing method of the door leaf 200 and the door frame 100 is not limited in this embodiment, as long as it can be fixed reliably, conveniently fixed and contact fixed. Exemplarily, the door leaf 200 and the door frame 100 can be fixed by any conventional structure such as a door lock, a magnet with opposite sexes attracting each other, or an electric telescopic rod.

[0039] It should be noted that the door leaf, door frame and other components of this embodiment can be prefabricated in a factory, installed on site and quickly constructed, which improves the construction efficiency of the assembled fire-fighting hidden door of this embodiment and reduces the occupation of the construction site.

[0040] In some embodiments, for example, Figure 1 , Figure 2 As shown, the door leaf 200 includes a strength plate 210 and a fireproof plate 230, and a filling gap is provided between the strength plate 210 and the fireproof plate 230, and the filling gap is filled with a foaming material 220. The strength plate 210 is set as an aluminum-plastic plate. The combination of the fireproof plate 230 and the foaming material 220 can effectively block flames and high temperatures, improve the fire resistance limit of the door leaf 200, and ensure that when a fire occurs, the door leaf 200 can delay the spread of the fire and win precious time for the evacuation of personnel. The aluminum-plastic plate as the strength plate 210 has a lighter weight than the traditional metal plate, which not only facilitates the installation and operation of the door leaf 200, but also reduces the burden on the door frame 100 and the hinge, and prolongs the service life of the door. The aluminum-plastic plate provides strength, and the fireproof plate 230 and the foaming material 220 provide fireproof capabilities, so that this embodiment can operate normally when a fire occurs, avoid accidents, and improve the reliability of this embodiment.

[0041] The aluminum-plastic panel has good corrosion resistance and is not easily affected by environmental factors. The surface of the aluminum-plastic panel is flat and easy to clean, and can be subjected to a variety of surface treatments, such as spraying, lamination, etc., so that this embodiment can meet different aesthetic and functional requirements.

[0042] It should be noted that in this embodiment, there is no restriction on the material of the fireproof board, as long as it can achieve fireproof effect. The fireproof board can be set as any finishing material according to the engineering finishing of the construction wall, such as gypsum board, wooden hanging board, etc., so as to diversify the decoration of this embodiment.

[0043] In some embodiments, the door leaf 200 further includes a cross brace 240, which is arranged between the strength plate 210 and the fireproof plate 230. A plurality of cross braces 240 are evenly arranged in the door leaf 200, and the cross brace 240 is arranged as an aluminum profile. The arrangement of the cross brace 240 can enhance the structural stability of the door leaf 200, especially when the present embodiment is used as an assembled fire-fighting hidden door, when the door leaf 200 needs to withstand a large external force in the event of a fire, the cross brace 240 can effectively prevent the door leaf 200 from deforming, maintain the flatness and strength of the door leaf 200, and facilitate the normal opening or overall removal of the door leaf 200. The aluminum profile is selected as the cross brace 240 material. Compared with other metal materials, the aluminum profile has a lighter weight. In combination with the strength plate 210 made of an aluminum-plastic plate, the overall weight of the door leaf 200 of the present embodiment is further reduced, which is convenient for the opening and closing of the door leaf 200, and also reduces the burden on the door frame 100 and the hinge.

[0044] It is understandable that the fireproof panels, aluminum-plastic panels, and cross braces can all be prefabricated in factories and can be quickly assembled during on-site installation, thereby improving the construction efficiency of this embodiment and reducing the floor space occupied by this embodiment during construction.

[0045] In some embodiments, for example, Figure 2 , Figure 3 As shown, a shielding assembly 300 is provided between the door leaf 200 and the door frame 100. The shielding assembly 300 includes a shielding plate 310. The shielding plate 310 is provided on the door frame 100 or the door leaf 200. The shielding plate 310 can shield the installation gap. The shielding plate 310 is provided between the door frame 100 and the door leaf 200, which can effectively shield the installation gap and make the connection between the door leaf 200 and the door frame 100 smoother.

[0046] In some embodiments, for example, Figure 1 , Figure 4As shown, the door leaf 200 includes a fixed portion 260 and a movable portion, the fixed portion 260 is fixedly connected to the door frame 100, and the movable portion is hingedly mounted on the fixed portion 260. The installation gap is set between the fixed portion 260 and the door frame 100. Setting the installation gap between the fixed portion 260 and the door frame 100 instead of between the movable portion and the door frame 100 can reduce the change of the installation gap that may be caused by the movable portion during the opening and closing process, thereby avoiding affecting the reliability and durability of this embodiment.

[0047] It is understandable that, due to the fixed connection between the door frame 100 and the fixing portion 260, there will be no change in the installation gap, thus avoiding the wear and maintenance requirements of the shielding assembly 300, and reducing long-term operating costs. In addition, setting the installation gap between the fixing portion 260 and the door frame 100 can also simplify the installation process of this embodiment, making it easier to fine-tune the installation gap or the shielding assembly 300 later to achieve a preset installation effect.

[0048] In some embodiments, for example, Figure 2 , Figure 3 As shown, the shielding plate 310 is disposed on the fixing portion 260 or the door frame 100, and the shielding plate 310 extends to the outside of the installation gap in a direction perpendicular to the door leaf 200. A bending plate 320 is extended on the shielding plate 310 at a position away from the installation gap, and the bending plate 320 extends in a direction away from the fixing portion 260 or the door frame 100 to shield the installation gap. The provision of the bending plate 320 can increase the effective shielding area between the shielding assembly 300 and the installation gap, ensure the shielding effect, and improve the overall fireproof performance of this embodiment. The shielding plate 310 extends out of the installation gap perpendicular to the door leaf 200 to prevent the shielding plate 310 from interfering with the installation process of the door frame 100 or the door leaf 200, thereby improving the reliability of this embodiment.

[0049] In some embodiments, for example, a bending plate 320 is provided at a position of the shielding plate 310 away from the installation gap, and the bending plates 320 are all extended in a direction close to the other shielding plate 310. Through the cooperation of the double bending plates 320, this embodiment can better adapt to changes in ambient temperature, and even if a slight displacement occurs between the door frame 100 and the door leaf 200 due to thermal expansion and contraction, this embodiment can also enable the shielding plate 310 and the bending plate 320 to maintain a good shielding effect.

[0050] In some embodiments, for example, Figures 2 to 4As shown, the door frame 100 is configured as a rectangular square tube, and the material of the door frame 100 is configured as an aluminum profile. A threaded hole is provided on the door frame 100 at a position facing the door leaf 200. Compared with circular or other shaped tubes, the rectangular square tube door frame 100 structure has better torsion and bending resistance, can provide stronger structural stability, and ensure that the door frame 100 does not deform when subjected to external forces or long-term use. Compared with other metals such as steel, aluminum profiles are used as the material of the door frame 100, which is lighter in weight, helps to reduce the total weight of the door frame 100, facilitates installation and maintenance, and also reduces the burden on the wall or supporting structure.

[0051] Aluminum profiles are also easy to cut, drill and bend, and are convenient for on-site processing and installation. That is to say, the use of aluminum profiles as door frames 100 can reduce the difficulty of processing threaded holes on the door frame 100. At the same time, the threaded holes can be easily fixed to the door leaf 200 or other components (such as hinges, locks, etc.), further making this embodiment easy to install.

[0052] In some embodiments, for example, Figure 2 As shown, the end of the door frame 100 close to the ground is provided with a skirting 270, and the skirting 270 is fixedly arranged on the door frame 100. The skirting 270 can prevent the bottom of the door frame 100 from daily wear and tear, such as scratches by cleaning tools, collisions caused by moving furniture, etc., and extend the service life of the door frame 100. It also helps to reduce the gap between the door frame 100 and the ground, prevent smoke and flames from spreading from the bottom during a fire, and improve the fireproof isolation effect of the door. The skirting 270 can also cover the installation marks and unevenness between the door frame 100 and the ground, improve the overall aesthetics of the door, and maintain the neat appearance of the building.

[0053] In some embodiments, for example, Figure 1 , Figure 2 , Figure 4 As shown, U-shaped steel 280 is provided at the corners of the door leaf 200. Due to its cross-sectional shape, the U-shaped steel 280 has high bending and compressive strength, which can significantly enhance the structural strength of the edges and corners of the door leaf 200, and prevent the door leaf 200 from being deformed or damaged during long-term use. In terms of performance, the U-shaped steel 280 has good heat resistance and stability, and can effectively prevent the fire from spreading at the edges and corners of the door leaf 200, improve the overall fireproof performance of the door, and ensure that when a fire occurs, this embodiment can block the fire source for a longer time. In addition, the provision of the U-shaped steel 280 can effectively protect the edge of the door leaf 200 from external impact or wear, extend the service life of the door leaf 200, and reduce the decline in the sealing performance of the door leaf 200 due to edge damage.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
