[0029] Preferably, the soundproof board 2 is provided with a plurality of support plates 31, and the support plates 31 are arranged on the soundproof board 2 in a staggered manner. Figure 1 、 Figure 2 As shown, a spring plate 34 is arranged on the top of the bracket 3 towards the side where the soundproof board 2 is installed. The end of the spring plate 34 is bent downward and inclined towards the bracket 3. The distance between the end of the spring plate 34 and the bracket 3 is greater than the thickness of the soundproof board 2. The distance between the lower edge of the end of the spring plate 34 and the top surface of the support plate 31 is less than the height of the soundproof board 2. The distance between the top surface of the baffle 33 and the bottom surface of the front end of the spring plate 34 is greater than the height of the soundproof board 2. With the above structure, the bottom edge of the soundproof board 2 can be inserted into the groove formed between the baffle 33 and the bracket 3 when the soundproof board 2 is installed. Then, the upper end of the soundproof board 2 is pressed towards the bracket 3, and the upper end of the soundproof board 2 is clamped between the end of the spring plate 34 and the bracket 3. In this way, the upper end of the soundproof board 2 is preliminarily fixed on the bracket 3 by the end of the spring plate 34, so as to facilitate the operator to install the locking screw 5 with both hands, thereby improving the safety during the installation process of the soundproof board 2. When the soundproof board 2 is disassembled, the locking screw 5 is loosened first, and then the soundproof board 2 is lifted upwards so that the bottom surface of the soundproof board 2 is higher than the baffle 33. In this way, the bottom edge of the soundproof board 2 is taken out of the bracket 3, and then the soundproof board 2 can be lowered to the bottom surface.

[0030] Preferably, the soundproof board 2 is provided with a plurality of support plates 31, and the support plates 31 are arranged on the soundproof board 2 in a staggered manner.
