DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Embodiment

[0025] Reference Figures 1 to 5 , A fireproof and heat-insulating solid wood door that is easy to disassemble and assemble in this embodiment includes a door frame 1 and a composite fireproof door 2. An articulated groove 3 is opened on one side inside the door frame 1. A rotating shaft 4 is rotatably connected to the inner side of the articulated groove 3. A connecting seat 5 is arranged on the rotating shaft 4. A clamping mechanism 6 is fixedly installed on the side of the composite fireproof door 2 close to the rotating shaft 4. The composite fireproof door 2 is detachably installed in the connecting seat 5 through the clamping mechanism 6;

[0026] The composite fireproof door 2 includes a solid wood base layer 21. A heat-resistant and heat-insulating layer 22 is fixedly connected to the outer side of the solid wood base layer 21. An insulating layer 23 is fixedly connected to the outer side of the heat-resistant and heat-insulating layer 22. A heat-resistant layer 24 is fixedly connected to the outer side of the insulating layer 23. It also includes a edging 25. After the solid wood base layer 21, a reinforcing layer 26, the heat-resistant and heat-insulating layer 22, the insulating layer 23, and the heat-resistant layer 24 are pressed together with fireproof glue, a composite door main body is formed. The edging 25 is adhesively and compositely connected to the periphery of the composite door main body;

[0027] The core of the composite fireproof door 2 in this application is its multi-layer structure, including the solid wood base layer 21 as the main body, and the outer layers are successively the heat-resistant and heat-insulating layer 22, the reinforcing layer 26, the insulating layer 23, and the heat-resistant layer 24. These hierarchical structures together improve the fire resistance and heat insulation of the door, ensuring that the door can still maintain its function and safety in extreme situations such as fires. The setting of the clamping mechanism 6 facilitates the installation and disassembly of the door, improving the convenience of use.

[0028] Reference Figure 4 , The heat-resistant and heat-insulating layer 22 is set as a vermiculite layer, and the reinforcing layer 26 is set as a stainless steel plate. Setting the vermiculite layer can further assist in heat-resistant and heat insulation, improving the overall heat insulation performance of this device. And setting the reinforcing layer 26 as a stainless steel plate can improve the overall use strength of this solid wood door and its overall use performance.

[0029] Reference Figure 4 , The insulating layer 23 is set as an aerogel layer, and the heat-resistant layer 24 is set as a polyimide layer. The aerogel layer as the insulating layer 23 uses its unique pore structure and high-efficiency heat insulation performance to greatly reduce the conduction of flame heat to the inside. Then there is the heat-resistant layer 24 composed of the polyimide layer, which further enhances the fireproof effect of the door body with its excellent high-temperature resistance, improving the overall use performance of this solid wood door.

[0030] Reference Figures 1 - 3, the card mounting mechanism 6 includes elastic clamping components 62 arranged at the upper and lower ends of the inner side of the composite fire door 2. Connecting seats 5 are integrally formed at the upper and lower ends of the rotating shaft 4. Insertion slots 61 are formed on the connecting seats 5. The composite fire door 2 is connected to the door frame 1 through the elastic clamping components 62. The elastic clamping components 62 include mounting plates 627. The mounting plates 627 are fixedly installed on one side of the composite fire door 2 close to the rotating shaft 4. Activity slots 621 are opened at the upper and lower ends of the mounting plates 627. Partition plates 622 are fixedly installed in the middle of the inner sides of the activity slots 621. Limit springs 623 are fixedly installed at the tops of the partition plates 622. Clamping plates 624 are fixedly installed at the tops of the limit springs 623. The tops of the clamping plates 624 penetrate through the mounting plates 627 and are inserted into the interiors of the insertion slots 61. Square notches 628 are opened at the outer ends of the mounting plates 627. The clamping plates 624 penetrate through the square notches 628. The insertion slots 61 are opened at both ends of the connecting seats 5, and the mounting plates 627 are fixed on one side of the composite fire door 2 close to the rotating shaft 4. When the mounting plates 627 are inserted into the connecting seats 5, the limit springs 623 reset and push the clamping plates 624 to move outwards, so that they are inserted into the insertion slots 61. This design enables the composite fire door 2 to be quickly and firmly installed on the connecting seats 5, greatly improving the convenience and stability of installation.

[0031] Reference Figures 1 - 3 , a connecting shaft 625 is fixedly installed at the bottom of the clamping plate 624. The bottom of the connecting shaft 625 penetrates through the partition plate 622. By providing the connecting shaft 625, during use, the clamping plate 624 can be pulled and twitched downwards by pulling the connecting shaft 625.

[0032] Reference Figures 1 - 3, an adjusting plate 626 is fixedly installed at the inner end of the coupling shaft 625. The combined side shape of the adjusting plate 626 and the clamping plate 624 is L-shaped. This L-shaped structure provides an intuitive and easy-to-operate interface for the installation and disassembly process. Users can simply pull or push the adjusting plate 626 to drive the clamping plate 624 to move in and out by the coupling shaft 625, thus quickly realizing the connection or separation between the composite fire door 2 and the connecting seat 5. This design not only improves the operation convenience but also reduces the complexity of installation and disassembly, especially suitable for places where the fire door needs to be frequently replaced or repaired. Secondly, the L-shaped structure has strong stability, which can ensure that the composite fire door 2 remains stable and reliable after installation. Through the precise control of the coupling shaft 625 by the adjusting plate 626, the clamping plate 624 can accurately insert into or disengage from the insertion slot 61, avoiding potential safety hazards caused by improper installation or loosening. This stability is crucial for the fire door as it directly relates to the door's sealing performance and fire resistance. When disassembly is required, simply pull the adjusting plate 626 at the bottom of the partition plate 622 in the movable slot 621. The inward movement of the adjusting plate 626 can drive the coupling shaft 625 to move the clamping plate 624 inward to disengage from the insertion slot 61. In this way, the limit between the connecting seat 5 and the mounting plate 627 is released, facilitating the disassembly and repair of the composite fire door 2. This fire-resistant and heat-insulating solid wood door not only has excellent fire-resistant and heat-insulating properties but also realizes convenient and efficient installation and disassembly through the unique clamping mechanism 6 design, providing a safer and more convenient fire door option for homes and commercial places.

[0033] Reference Figures 1 - 3 , fixing plates 7 are fixedly installed at the four corners of the door frame 1. An installation hole 8 is opened in the middle of the outer side of the fixing plate 7. The installation hole 8 is set as a countersunk hole. The cooperation of the fixing plate 7 and the installation hole 8 enables the quick installation of the door frame 1, facilitating the installation of the door frame 1 indoors. The countersunk hole design allows the head of the fastener to be hidden inside the hole and not protrude from the surface of the door frame 1, maintaining the overall aesthetics of the door. The fastener installed through the countersunk hole can be more firmly fixed on the door frame 1, enhancing the connection strength between the door and the wall and improving the stability of the door.

[0034] Principle of use and advantages: The solid wood base layer 21 is located in the inner middle of the door, providing a solid foundation for the entire door body. On the outer side of the solid wood base layer 21, a layer of vermiculite layer is closely attached as the heat-resistant and heat-insulating layer 22, effectively slowing down the erosion of the fire on the internal solid wood base layer 21 and maintaining the temperature stability of the door body. Immediately following the heat-resistant and heat-insulating layer 22 is a layer of aerogel layer as the heat-insulating layer 23. This layer, through its unique pore structure and high-efficiency heat-insulating performance, greatly reduces the conduction of the heat of the flame to the inside. On the outer side of the heat-insulating layer 23 is a heat-resistant layer 24 composed of a polyimide layer. With its excellent high-temperature resistance performance, it further enhances the fireproof effect of the door body. This composite fireproof door 2 is also provided with a stainless steel plate as the reinforcement layer 26, ensuring the stability and durability of the door body in extreme environments such as high temperature and fire. In summary, this composite fireproof door 2, with its multi-layer protection structure and high-quality materials, provides reliable fire protection for families and commercial places;

[0035] By setting the clamping mechanism 6, during the use of this device, when the composite fireproof door 2 needs to be installed at the door frame 1, the mounting plate 627 can be inserted into the inside of the connecting seat 5. At this time, the limit spring 623 resets to drive the clamping plate 624 to move outwards. The clamping plate 624 moves outwards and can be inserted into the inside of the insertion slot 61. At this time, through the cooperation of the clamping plate 624 and the insertion slot 61, the mounting plate 627 can be assisted to be clamped inside the connecting seat 5. In this way, the composite fireproof door 2 can be quickly installed on the outside of the rotating shaft 4. When disassembly is required, only the adjusting plate 626 at the bottom of the partition plate 622 in the movable slot 621 needs to be pulled. The adjusting plate 626 moves inwards to drive the connecting shaft 625 to move, driving the clamping plate 624 to move inwards. The clamping plate 624 moves inwards and can be separated from the insertion slot 61. The clamping plate 624 and the insertion slot 61 are separated from each other, causing the connection between the connecting seat 5 and the mounting plate 627 to lose the limit, facilitating the overall disassembly and assembly of this composite fireproof door 2 in this device, improving the overall disassembly and assembly convenience of this device, and effectively improving the installation convenience of this solid wood unit.
