[0022] Sound wave can be blocked by soundproof board 3, first slot hole 9, second slot hole 10 and third slot hole 11 form stepped sound absorption, so that sound wave rebounds in first slot hole 9, achieving sound attenuation effect, heat insulation plate 4 can block heat, and the equidistantly distributed partitions 14 can divide the internal space of groove body 12 into equidistant cavities, further enhancing the heat insulation property, and the reinforcing rib 15 fixedly connected in support plate 5 can support heat insulation plate 4 and soundproof board 3, preventing heat insulation plate 4 and soundproof board 3 from being broken, and guard plate 1 and bottom plate 2 can further protect soundproof board 3 and heat insulation plate 4.

[0023] Referring to Figures 3-4 In the embodiment, the end of the guard plate 1 and the soundproof board 3 close to each other is fixedly connected with a first connecting layer 6, the through-hole 8 and the first slot hole 9 are in communication, in use, sound waves can be guided into the inner wall of the second slot hole 10 through the communication between the through-hole 8 and the first slot hole 9, so that the sound waves rebound multiple times to achieve sound attenuation effect, the first slot hole 9 and the second slot hole 10 are hexagonal, and the third slot hole 11 is octagonal, in use, the hexagonal shape allows the sound waves to rebound multiple times, and the octagonal third slot hole 11 can further weaken the intensity of the sound waves and enhance the sound attenuation effect.

[0024] Referring to Figures 4-6 In the embodiment, the end of the soundproof board 3 and the heat insulation plate 4 close to each other is fixedly connected with a second connecting layer 16, and the end of the heat insulation plate 4 and the support plate 5 close to each other is fixedly connected with a third connecting layer 17, in use, the second connecting layer 16 can connect the soundproof board 3, so that the support plate 5 enhances the strength of the soundproof board 3 and the heat insulation plate 4, avoiding the soundproof board 3 and the heat insulation plate 4 from being broken, the end of the support plate 5 and the bottom plate 2 close to each other is fixedly connected with a fourth connecting layer 18, and the materials of the first connecting layer 6, the second connecting layer 16, the third connecting layer 17 and the fourth connecting layer 18 are all epoxy resin, in use, the fourth connecting layer 18 can connect the board members to each other, enhancing the stability in use.

[0025] Referring toFigures 2-6 In the embodiment, the fixed blocks 7 are fixed at the four corners of the bottom plate 2, and the upper end inner walls of the fixed blocks 7 are fixed at the upper end four corners of the protective plate 1. In use, the fixed blocks 7 can further improve the firmness between the plates and the stability of the plates in use. The thickness of the supporting plate 5 is greater than that of the sound insulation plate 3 and the heat insulation plate 4. The thickness of the connecting layer is one millimeter.

[0026] In use, the sound waves enter the first slot hole 9 from the through hole 8 and continuously rebound in the first slot hole 9. When subsequent sound waves enter, the rebounding sound waves in the first slot hole 9 enter the second slot hole 10, so that the sound waves continuously rebound in the slot holes, achieving the effect of weakening the sound waves, thereby achieving sound insulation. When heat impacts the heat insulation plate 4, the partition plate 14 divides the groove body 12 into cavities distributed at equal intervals. Since air is a poor conductor of heat, the transmission of heat is weakened, achieving heat insulation effect. Since the sound insulation plate 3 and the heat insulation plate 4 are distributed with a large number of slot holes, the supporting plate 5 and the reinforcing ribs 15 installed inside can support the sound insulation plate 3 and the heat insulation plate 4, improve the overall strength of the acrylic plate, and avoid damage, thereby achieving the adaptability of the acrylic plate in special occasions requiring sound insulation and heat insulation.

[0027] Through the above steps, the sound insulation plate 3 can block sound waves, the first slot hole 9, the second slot hole 10 and the third slot hole 11 form a stepped sound absorption, so that the sound waves rebound in the first slot hole 9. The heat insulation plate 4 can block heat. The equidistantly distributed partition plates 14 can divide the internal space of the groove body 12 into equidistant cavities. The reinforcing ribs 15 fixed in the supporting plate 5 can support the heat insulation plate 4 and the sound insulation plate 3 to prevent the heat insulation plate 4 and the sound insulation plate 3 from being broken. The protective plate 1 and the bottom plate 2 can further protect the sound insulation plate 3 and the heat insulation plate 4, solving the problem that the noise reduction and heat insulation performance of the acrylic plate is poor in use and difficult to meet the use requirements in special occasions.
