[0021] like Figure 1~2 As shown, the utility model proposes: a guide plate for a wind box, comprising a plate body 1 and a box body 5 fixed thereto {the plate body 1 is made of a hard material, such as stainless steel or plastic (such as ABS, PP, PVC, etc.)};

[0022] It also includes a noise reduction layer 2 (the noise reduction layer 2 is a porous sound-absorbing material layer, etc., made of open-pore foam or sound-absorbing felt, etc.) fixedly mounted on the windward side of the board body 1. Figure 2 As shown, wind is provided to blow toward the noise reduction layer 2 to provide sound absorption to reduce noise;

[0023] The cushion layer 3 (such as Figure 2 As shown, the upper right side surface and the right side surface of the bottom end of the plate body 1 are respectively fixed with a cushion layer 3, which can be fixed by bonding or other methods);

[0024] Several groups of fixing components 4 (such as Figure 2As shown, the cushion layer 3 is used as a supporting connection surface for mounting the plate body 1, which can improve the stability after installation and during use);

[0025] The two ends of the surface of the noise reduction layer 2 that pass through the wind are smoothly transitioned to the outside of the box 5 (such as Figure 2 As shown, the top left side of the noise reduction layer 2 and the left side of the top are connected with the contact surface on the box body 5 without height difference, that is, the thickness of the noise reduction layer 2 extending toward the box body 5 is gradually reduced, and an arc-shaped transition is generated to the outer surface of the box body 5), when the wind is guided, the wind flowing on the inner wall of the box body 5 can be smoothly flowed to the noise reduction layer 2, and the flow stability is high;

[0026] The fixing assembly 4 is provided with a plurality of groups (such as Figure 1 As shown, multiple groups of fixing components 4 are evenly distributed from left to right to improve the stability and strength of the board body 1 after installation);

[0027] In order to implement the above-mentioned fixing assembly 4, it is proposed that Figure 1~2 As shown, the specific structure and composition of the fixing component 4 can be as follows: the fixing component 4 includes a through hole 41 (such as Figure 2 As shown, the perforation 41 penetrates the noise reduction layer 2, the plate body 1 and the cushion layer 3, that is, it passes through the windward side and the leeward side, and also penetrates into the box body 5);

[0028] and a bolt 42 movable in the through hole 41, the bolt 42 is threadedly connected to the plate body 1 and the box body 5 respectively (according to the above, when the bolt 42 is inserted into the through hole 41 and then enters the position of the plate body 1, it is first threadedly connected and then threadedly connected to the box body 5, so as to fix the plate body 1, and at the same time, the cushion layer 3 is attached to the box body 5 for stability, thereby increasing the stability strength);

[0029] The bolt 42 after the box body 5 is threadedly connected is directed toward the outside of the noise reduction layer 2 and forms a filling groove (such as Figure 2 As shown, after the bolt 42 is installed in the through hole 41, the through hole 41 is not filled up, resulting in a filling groove);

[0030] The fixing assembly 4 also includes a filling block 43 which is fitted into the filling groove, and the block surface of the filling block 43 facing outward smoothly transitions to the windward surface of the noise reduction layer 2, that is, the thickness of the noise reduction layer 2 is adapted to the depth of the filling groove so as to be filled completely accordingly (the filling block 43 is also made of the same material as the noise reduction layer 2, and is provided to fill the groove to improve the effect of the noise reduction layer 2).

[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
