[0025] A first groove 17 is provided on the side of the frame 1, and a second groove 18 is provided on the side of the frame 1. The internal structures of the first groove 17 and the second groove 18 are the same. The inner wall of the second groove 18 is fixedly connected with a first spring 11, and the end of the first spring 11 away from the inner wall of the second groove 18 is fixedly connected with a fixing rod 12. The surface of the fixing rod 12 is slidably connected to the inner wall of the second groove 18. The surface of the fixing rod 12 is fixedly connected with a second spring 13. The end of the second spring 13 away from the fixing rod 12 is fixedly connected with a cross plate 14, and the cross plate 14 is slidably connected to the inner wall of the second groove 18. A first slot 21 is provided on the side of the frame 1, and a second slot 22 is provided on the side of the frame 1. The cross plate 14 matches the first slot 21 and the second slot 22, and can be inserted into the first slot 21 or the second slot 22 in the other frame 1, thereby sealing the gap between the two frames 1 to prevent formaldehyde from being emitted from the gap between the two frames 1 after installation, thereby further reducing the formaldehyde concentration in the room.
[0026] A first sliding groove 19 is provided inside the frame 1, and a mounting plate 2 is provided on one side of the frame 1. The surface of the mounting plate is fixedly connected to a bevel fixing rod 4, and the surface of the bevel fixing rod 4 slides with the inside of the frame 1. A second sliding groove 20 is provided inside the bevel fixing rod 4, and the inner wall of the second sliding groove 20 is fixedly connected to a third spring 16. The end of the third spring 16 away from the second sliding groove 20 is fixedly connected to a limit block 15 with a trapezoidal cross-section, and the surface of the limit block 15 slides with the inner wall of the second sliding groove 20. The surface of the mounting plate 2 is fixedly connected to a fixing bolt 3 for fixing the mounting plate 2 to the wall.
[0027] Furthermore, the base material layer 5 is made of high-strength solid wood material, which improves the strength and stability of the board. The fireproof layer 6 is made of glass fiber, which can maintain the integrity of the structure at high temperatures and can effectively avoid heat transfer. The middle layer 7 is made of thin wood veneers, which provides additional structural support and further enhances its stability. The drying layer 8 is made of zeolite, which can absorb water molecules to prevent the formaldehyde removal layer 9 from affecting its performance in a humid environment. The formaldehyde removal layer 9 is made of activated carbon and can effectively adsorb formaldehyde in the air. Its microporous structure provides a large surface area, which improves the adsorption efficiency. The covering layer 10 is made of PET film, which has good wear resistance, scratch resistance and corrosion resistance, protects the underlying structure, and enhances the overall durability of the board.
[0028] During the installation process, first fix the mounting plate 2 to the wall, and then place the frame 1 on the mounting plate 2, and then insert the inclined fixing rod 4 into the interior of the frame 1. During this process, the interior of the frame 1 squeezes the inclined surface of the limit block 15, so that the limit block 15 retracts into the second sliding groove 20, and causes the third spring 16 to undergo elastic deformation. When the surface of the frame 1 is completely in contact with the surface of the mounting plate 2, the limit block 15 and the first sliding groove 19 correspond to each other, so that the limit block 15 enters the first sliding groove 19 through the elastic force of the third spring 16, thereby fixing the frame 1. At the same time, inside the frame 1, the fixing rod 12 is pushed out by the inclined fixing rod 4, and then the fixing rod 12 pushes the second spring 13 to stretch and push the cross plate 14 out of the interior of the frame 1.
[0029] Furthermore, when installing another PET board, the surface of the frame 1 is fitted with the surface of another frame 1, and the horizontal plate 14 will enter the interior of the frame 1 due to the thrust, and the second spring 13 will undergo elastic deformation. When the other board is installed, the horizontal plate 14 will enter the interior of the first card slot 21 and the second card slot 22 respectively through the elastic force of the second spring 13, thereby completing the sealing between the two boards, reducing the concentration of formaldehyde emitted from the inside, and improving safety.
[0030] Working principle: During the installation process, first fix the mounting plate 2 to the wall, then place the frame 1 on the mounting plate 2, and then insert the inclined fixing rod 4 into the interior of the frame 1. During this process, the interior of the frame 1 squeezes the inclined surface of the limit block 15, so that the limit block 15 retracts into the second sliding groove 20, and causes the third spring 16 to undergo elastic deformation. When the surface of the frame 1 is completely in contact with the surface of the mounting plate 2, the limit block 15 corresponds to the first sliding groove 19, so that the limit block 15 enters the first sliding groove 19 through the elastic force of the third spring 16, thereby fixing the frame 1. The second spring 13 is pressed against the second plate 14 and the second plate 14 is pressed against the second plate 14. The second plate 13 is pressed against the second plate 14 and the second plate 14 is pressed against the second plate 14. The second plate 13 is pressed against the second plate 14 and the second plate 14 is pressed against the second plate 14.
