[0019] When in use, the graphite homogeneous board 1 is used as the core board of the wooden door. The graphite homogeneous board 1 is made of graphite polystyrene particles as the main raw material and graphite homogeneous filler as an environmentally friendly material. The production process does not require high temperature and high pressure. The product is harmless, pollution-free, and non-radioactive. Compared with traditional door cores, the inorganic materials mainly used in the graphite homogeneous board are more environmentally friendly. According to authoritative test reports, the formaldehyde emission of the graphite homogeneous board is far lower than the limit value required by the national Enf level standard. The graphite homogeneous board 1 is a combination of organic materials and inorganic mineral glues such as silicon and calcium. As a core board of a wooden door, it has low water absorption and improved moisture-proof performance. In order to avoid the phenomenon of skewing and dislocation when the graphite homogeneous board 1 is clamped between two facing wooden boards 2, a card slot 3 and a card strip 4 are added. After the card strip 4 is pushed into the card slot 3, it ensures that the facing wooden board 2 will not shake left and right on the surface of the graphite homogeneous board 1.

[0020] The fixing parts include a screw 6, and side grooves 5 are provided at both ends of the clip 4. The screw 6 and the side grooves 5 correspond one to one. The screw 6 is screwed on the surface of the side groove 5, and the screw 6 passes through the clip 4 and is screwed on the surface of the veneer wood board 2. The clip 4 is a detachable structure on the surface of the veneer wood board 2. The clip 4 is fixed to the veneer wood board 2 by a screw 6, and the clip 4 can also be bonded to the surface of the veneer wood board 2 by glue.

[0021] The board surface size of the graphite homogeneous plate 1 is smaller than the board surface size of the facing wooden board 2. An annular groove is reserved between the outer contour of the graphite homogeneous plate 1 and the two facing wooden boards 2 for installing the sleeve frame 7. Connecting plates 8 are integrally formed on the top and bottom surfaces of the four corners of the sleeve frame 7. Notches 9 are opened at the four corners of the facing wooden board 2. The connecting plates 8 and the notches 9 match. The sleeve frame 7 has a square frame structure. The sleeve frame 7 is sleeved on the outside of the graphite homogeneous plate 1. The outer contour size of the sleeve frame 7 is equal to the outer contour size of the facing wooden board 2. The height of the sleeve frame 7 is equal to the thickness of the graphite homogeneous plate 1. The connecting plate 8 has an "L"-shaped plate structure. The height of the connecting plate 8 is equal to the thickness of the facing wooden board 2. The notch 9 is an "L"-shaped groove. The height of the notch 9 is equal to the thickness of the facing wooden board 2. After the sleeve frame 7 is sleeved on the graphite homogeneous plate 1, the connecting plate 8 is inserted into the notch 9. A reserved hole 10 is provided on the surface of the connecting plate 8 . The reserved hole 10 is a convex circular hole. A second screw 11 is inserted into the reserved hole 10 . The second screw 11 penetrates the reserved hole 10 and is screwed to the surface of the notch 9 .

[0022] When in use, a sleeve frame 7 is sleeved on the outer side of the graphite homogeneous plate 1, which not only realizes edge protection of the graphite homogeneous plate 1, but also after the connecting plate 8 integrally formed on the top surface and the bottom surface of the sleeve frame 7 is inserted into the notch 9, the connecting plate 8 is fixed in the notch 9 by using screws 11, so that the two facing wooden boards 2 are fixed together. The two facing wooden boards 2 fixed together tightly clamp the graphite homogeneous plate 1. Since the clamping strip 4 is a square strip and the clamping slot 3 is a square slot, it is convenient to directly stack the facing wooden board 2 on the graphite homogeneous plate 1.

[0023] A composite board is formed by stacking a graphite homogeneous plate 1 and a facing wood board 2 and sleeved with a sleeve frame 7 in a groove between the graphite homogeneous plate 1 and the facing wood board 2; edge sealing strips 12 are bonded to both sides of the composite board, the long side length of the graphite homogeneous plate 1 is greater than the long side length of the composite board, and edge sealing strips 13 are inserted into the groove between the ends of the two edge sealing strips 12, and one side of the edge sealing strips 13 is bonded to the surface of the composite board; the edge sealing strips 12 and 13 are installed around the composite board to not only protect the edges of the composite board, but also enhance the aesthetics of the edges of the composite board.

[0024] The assembly process of wooden doors is as follows: The core material of wooden doors is graphite homogeneous board 1, which is made of graphite polystyrene particles as the main raw material and graphite homogeneous filler. It is an environmentally friendly material. Its production process does not require high temperature and high pressure. The product is harmless, pollution-free and non-radioactive. The formaldehyde emission of graphite homogeneous board is far lower than the limit value required by the national Enf grade standard, and it has low water absorption and good moisture-proof performance.

[0025] The two sides of the graphite homogeneous plate 1 are provided with facing wood boards 2 as the appearance layer of the wooden door. The graphite homogeneous plate 1 and the facing wood boards 2 are connected by a limit clamp to prevent deflection and misalignment when stacked. The limit clamp includes a slot 3 provided on the surface of the graphite homogeneous plate 1 and a clip 4 installed on the surface of the facing wood boards 2. The shapes and sizes of the slot 3 and the clip 4 match to ensure that the clip 4 can be firmly inserted into the slot 3.

[0026] Fixing of the limit clamp: The clamping strip 4 is installed on the surface of the facing wood board 2 by means of a fixing member (such as a screw 6 or glue). The screw 6 is screwed on the surface of the side groove 5 and penetrates the clamping strip 4, and finally screwed on the facing wood board 2, so as to realize the detachable fixing of the clamping strip 4.

[0027] Installation of the sleeve frame 7: An annular groove is reserved between the outer contour of the graphite homogeneous plate 1 and the two facing wood boards 2 for installing the sleeve frame 7. Connecting plates 8 are provided at the four corners of the sleeve frame 7 to match the notches 9 on the facing wood boards 2. After the sleeve frame 7 is sleeved on the outside of the graphite homogeneous plate 1, the connecting plates 8 are inserted into the notches 9 and fixed to the surface of the notches 9 by screws 11, thereby fixing the two facing wood boards 2 together and tightly clamping the graphite homogeneous plate 1.

[0028] Formation and edge protection of composite board: The graphite homogeneous board 1 and the facing wood board 2 are stacked, and the groove body between them is sleeved with a sleeve frame 7 to form a composite board. Edge sealing wood strips 12 are bonded to both sides of the composite board to improve the strength and aesthetics of the edge. Since the long side length of the graphite homogeneous board 1 is greater than the long side length of the composite board, edge sealing wood strips 13 can be inserted into the groove body between the two edge sealing wood strips 12, and one side of the edge sealing wood strips 13 is bonded to the surface of the composite board to further strengthen the protection of the edge of the composite board.

[0029] Overall structure and function: Through the above structure and connection method, the graphene wooden door provided by the present invention not only has fireproof and moisture-proof properties, but also has a stable structure and beautiful appearance. The environmental protection and moisture-proof properties of the graphite homogeneous plate make the wooden door healthier and more durable. The use of the limit card and the sleeve frame 7 ensures the structural stability and overall aesthetics of the wooden door.
