[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] In the following description, numerous specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein, so the present utility model is not limited to the specific embodiments of the specification disclosed below.

[0017] Refer to Figures 1-4 , the present utility model provides a technical solution: a height-adjustable diffuse reflection plate, comprising a base 1, a bracket main body 2, a diffuse reflection plate main body 3 and a lifting assembly 4. The bracket main body 2 is mounted on the base 1, and reinforcing ribs 5 and fixed angle irons 6 are arranged between the bracket main body 2 and the base 1. The fixed angle irons 6 are arranged perpendicular to the bracket main body 2 and the base 1, and the reinforcing ribs 5 are arranged at an included angle with the bracket main body 2 and the base 1. This structure improves the assembly strength between the bracket main body 2 and the base 1. Further, rollers 7 are arranged on the peripheral edge of the base 1 to drive the whole to move, and a positioning screw 8 is arranged at a position close to the rollers 7. The positioning screw 8 is in threaded assembly connection with the base 1, and a gasket is arranged at the end thereof, so that by twisting the positioning screw 8, the gasket abuts against the ground to achieve the effect of fixing the position of the base 1.

[0018] As shown in Figure 2 , a mounting frame 9 is fixedly arranged on the back of the diffuse reflection plate main body 3. The mounting frame 9 is in a "mouth" shape, and is fixedly connected with the peripheral edge positions of the diffuse reflection plate main body 3 through bolts. In order to improve the strength of the mounting frame 9, a cross-shaped reinforcing rod is added in the middle part thereof, and the reinforcing rod is attached to the back of the diffuse reflection plate main body 3.

[0019] With reference to Figure 2-4As shown, in this application, the lifting assembly 4 is provided in two sets and is equidistantly distributed along the length of the diffuse reflector body 3. Specifically, the lifting assembly 4 includes a connector 401, a movable block 402, and a guide rail 403. The connector 401 is fixed to the mounting frame 9, and the guide rail 403 is fixed to the support body 2. One end of the movable block 402 is assembled and connected to the connector 401, and the other end is slidably mounted on the guide rail 403, so that the diffuse reflector body 3 moves up and down on the support body 2 with the lifting assembly 4. The support body 2 is provided with a limiting block 404 at the lower end of the guide rail 403. In the initial state, the movable block 402 abuts against the limiting block 404, and the movable block 402 and the guide rail 403 are in contact. The end face of the 03 contact is provided with a mounting groove, and a clamping block 405 is provided in the mounting groove. A locking screw 406 is provided on the outside of the movable block 402. The part of the screw 406 that extends into the mounting groove abuts against the clamping block 405, and the locking screw 406 is positioned directly opposite the middle position of the clamping block 405, so that the locking screw 406 evenly presses the clamping block 405. At the same time, the surface of the clamping block 405 is provided with a guide protrusion, which is engaged in a guide groove provided in the inner wall of the mounting groove. This structure allows the clamping block 405 to move under the action of the locking screw 406, and the clamping block 405 can increase the contact area between itself and the guide rail 403 to ensure the clamping effect.

[0020] The device has a mounting bracket 9 mounted on the diffuse reflector plate body 3. First, the connector 401 is fixedly mounted on the mounting bracket 9 with bolts. Then, the movable block 402 is fixedly mounted on the connector 401 with screws. At the same time, the guide rail 403 is mounted on the bracket body 2 with bolts. After the assembly is completed, the diffuse reflector plate body 3 is lifted so that the movable block 402 is aligned with the guide rail 403. The movable block 402 is slidably mounted on the guide rail 403. After the diffuse reflector plate body 3 is released, the movable block 402 abuts against the limiting block 404, thereby determining the initial use height position of the diffuse reflector plate body 3.

[0021] When the height of the diffuse reflector body 3 needs to be adjusted, push the diffuse reflector body 3 upwards, causing the movable block 402 to move upwards on the guide rail 403. The locking screw 406 is threadedly connected to the movable block 402. After the diffuse reflector body 3 moves to the required height, tighten the locking screw 406, causing the locking screw 406 to press against the clamping block 405. The clamping block 405 is pressed against the side of the rail, thereby fixing the position of the diffuse reflector body 3. The threaded assembly method can prevent the locking screw 406 from rotating and loosening, ensuring the clamping effect on the clamping block 405. To facilitate locking... The operation of the locking screw 406 involves a handle at the point where the locking screw 406 extends out of the movable block 402, giving the locking screw 406 an "L" shape. This structure connects the mounting bracket 9 and the support body 2, allowing the diffuse reflector body 3 to be raised and lowered to adjust its height during use. Tightening the locking screw 406 causes it to press against the clamping block 405, which in turn presses against the side of the guide rail 403 to fix the height of the diffuse reflector body 3, thus meeting the dynamic adjustment needs of the diffuse reflector body 3 and improving its adaptability to various usage scenarios.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
