[0022] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0023] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0024] like Figure 1-Figure 4 As shown, an anti-deformation composite door provided by the utility model includes a door leaf body 10, the door leaf body 10 includes a door leaf frame 101 and door leaf panels 104 respectively arranged on the upper and lower surfaces of the door leaf frame 101, the door leaf frame 101 has an inner hollow area, the inner hollow area is paved with a plurality of bridge hole mechanical filling plates 102 arranged in parallel at intervals, the inner hollow area is also filled with anti-deformation steel pipes 103, and the anti-deformation steel pipes 103 are arranged parallel to the bridge hole mechanical filling plates 102.

[0025] The door frame 101 of the present invention is provided with a plurality of spaced, parallel, bridge-hole mechanical filling plates 102. This bridge-hole structure evenly distributes external forces to prevent deformation, effectively preventing deformation of the door body 10 during use. Furthermore, the bridge-hole mechanical filling plates 102 are segmented and filled within the door frame 101, preventing deformation while reducing the weight of the door body 10, thereby effectively preventing the door hinge from falling off during use. Furthermore, anti-deformation steel pipes 103 are provided within the door frame 101. The hardness of these anti-deformation steel pipes 103 serves as a supporting framework, increasing the overall strength of the door body 10 and further preventing deformation of the door body 10.

[0026] It should be noted that the bridge hole mechanical filling plate 102 of this embodiment is made of solid wood into a unique tubular structure, which can evenly disperse external forces and ensure that it does not deform. The tubular structure makes the bridge hole mechanical plate 60% lighter than the same solid wooden board. At the same time, the bridge hole mechanical plate can also effectively prevent the diffusion of temperature and achieve good thermal insulation effect.

[0027] As a preferred embodiment, each of the bridge hole mechanical filling plates 102 and the anti-deformation steel pipes 103 are laid along the length of the door frame 101. This allows the bridge hole mechanical filling plates 102 and the anti-deformation steel pipes 103 to cooperate with each other to fill the internal space, thereby increasing the strength of the door body 10 and making it less prone to deformation and cracking.

[0028] As a preferred embodiment, both ends of the bridge mechanical filling plate 102 are fixed to the door frame 101 by means of cotter pins. Using cotter pins to securely connect the bridge mechanical filling plate 102 to the door frame 101 is simple to operate and improves the reliability of the connection between the bridge mechanical filling plate 102 and the door frame 101.

[0029] As a preferred embodiment, the bridge hole mechanical filling plate 102 is a circular bridge hole mechanical filling plate 102 .

[0030] In this embodiment, the conventional bridge hole mechanical filling panels 102 are often square bridge hole mechanical filling panels 102. However, since circular bridge hole mechanical filling panels 102 can better echo sound, the sound insulation effect of square bridge hole mechanical filling panels 102 is not as good as that of circular bridge hole mechanical filling panels 102. In addition, circular bridge hole structures have a stronger load-bearing capacity than square bridge hole structures. Therefore, using circular bridge hole mechanical filling panels 102 not only improves the sound insulation effect of the door leaf body 10, but also increases the load-bearing capacity of the door leaf body 10, thereby strengthening the door leaf body 10 structure.

[0031] As a preferred embodiment, two anti-deformation steel pipes 103 are provided, and the two anti-deformation steel pipes 103 are symmetrically arranged in the inner hollow area with the first central axis of the door body 10 as the symmetry axis. This can balance the force on the door body 10 and better prevent the door body 10 from deformation.

[0032] As a preferred embodiment, there are five bridge tunnel mechanical filling plates 102, and a first gap, a second gap, a third gap and a fourth gap are formed in sequence along the first direction between the five bridge tunnel mechanical filling plates 102, and the first gap and the fourth gap are respectively laid with the anti-deformation steel pipe 103.

[0033] The two anti-deformation steel pipes 103 of this embodiment are located between the bridge hole mechanical filling plates 102, which help to increase the overall strength of the door leaf body 10 and improve the sound insulation and other properties of the door leaf body 10.

[0034] As a preferred embodiment, the door frame 101 is constructed from four solid wood planks. The solid wood frame 101 of this embodiment, with its surroundings framed, ensures its sturdiness and facilitates subsequent installation of the door hinge and keyholes. Furthermore, the solid wood planks effectively secure the bridge opening mechanical filler plate 102 within the door frame 101.

[0035] As a preferred embodiment, an adhesive layer is provided between the door panel 104 and the door frame 101 .

[0036] In this embodiment, the door frame 101 is formed by sandwiching two door panels 104 in the middle and then cold-pressing them on a cold press to form the door body 10. Before pressing, the door panels 104 are coated with glue on a glue coating machine to ensure that they can be firmly bonded to the door frame 101. After the door body 10 is pressed, the anti-deformation steel pipe 103 is filled in the middle of the door frame 101 to prevent deformation of the door body 10 by utilizing the hardness and other material properties of the material.

[0037] As a preferred embodiment, the door leaf body 10 is provided with edge bands 105 around it. The edge bands 105 are used to band the door leaf body 10 by an edge banding machine, so that the door leaf body 10 forms a closed whole, effectively preventing the door leaf body 10 from swelling or deformation.

[0038] As a preferred embodiment, the surface of the door panel 104 is provided with tri-amine paper or PVC film, which can improve the aesthetics of the door body 10 .

[0039] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
