[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] This utility model provides a novel adjustable diffuse reflector device. Please refer to [link / reference]. Figures 1-9 The system includes a diffuser frame assembly and a bracket 5. Four sets of casters 8 are fixedly installed at the bottom of the bracket 5, allowing for easy movement and transport. The diffuser frame assembly has pitch shafts 2 on both sides. Three sets of slewing supports 4 arranged in an I-shape are fixedly installed at both ends of the bracket 5, with the pitch shafts 2 rotatably connected to the slewing supports 4 and secured by locking bolts 3. The diffuser frame assembly can pitch relative to the bracket 5 around the pitch shafts 2 and is fixed at any angle by the locking bolts 3. Tightening the locking bolts 3 presses the pitch shafts 2 against the slewing supports 4, thus locking the pitch shafts 2.

[0035] The diffuser frame assembly includes: a profile frame 11, a diffuser 1, a pressure plate 9, a handle 10, and mounting corner pieces 12;

[0036] Both ends of the profile frame 11 are fixedly installed with pitch axes 2. The diffuse reflector 1 is fixedly installed in the profile frame 11. One side of the profile frame 11 is fixedly installed with a pressure plate 9 by bolts so that it can press against the surface of the diffuse reflector 1 to fix the diffuse reflector 1. Both ends of the profile frame 11 are fixedly installed with handles 10 for carrying the diffuse reflector frame assembly. Both the upper and lower ends of the profile frame 11 are fixedly installed with corner brackets 12 for fixing the diffuse reflector frame assembly in the packaging box. The profile frame 11 is made of standard 3060 aluminum profile spliced ​​together by product corner brackets.

[0037] The arc groove in the middle of the slewing support 4 is rotatably connected to the pitch axis 2, and the pitch axis 2 is limited by the stop block 13. The stop block 13 is L-shaped, and the top of the stop block 13 is inserted into the groove at the top of the slewing support 4. The bottom of the stop block 13 is fixedly installed on the middle of the slewing support 4 by the internal hex bolt 15. The lower end of the slewing support 4 is provided with a second graduation line, which is used to cooperate with the first graduation line on the pitch axis 2 so that the angle can be quickly adjusted to the correct position.

[0038] One end of the pitch axis 2 is a semi-circular groove structure, and the other end of the pitch axis 2 is a square structure. The middle end of the pitch axis 2 is a light axis. The semi-circular groove structure is slidably connected to the locking bolt 3, and one end of the locking bolt 3 is threaded into the threaded groove on the rotary support 4. The square structure is fixedly installed on the profile frame 11, and the light axis is located in the rotary support 4. The outer side of the semi-circular groove structure of the pitch axis 2 is provided with a first engraving line. The first engraving line is distributed at an angle of 10° about the rotation axis as a reference for adjusting the angle, so as to facilitate the quick adjustment of the diffuser plate angle.

[0039] Four sets of lead screw seats 16 are fixedly installed on the inner side of the bottom end of the bracket 5. Lead screws 7 are threadedly connected to the lead screw seats 16. A crank handle 6 is fixedly installed on the top of the lead screw 7, and a foot 14 is fixedly installed on the bottom of the lead screw 7. The bracket 5 can be leveled by the crank handle 6 and the lead screw 7 to adapt to the undulating terrain.

[0040] The specific steps during runtime are as follows:

[0041] First, move the bracket 5 to a suitable position using the casters 8. If the ground is uneven, use the crank handle 6 to raise or lower the screw 7 and the foot 14. This will ensure that the bracket 5 is in a horizontal position and avoids tilting. Then, fix the pitch axis 2 to the corresponding slewing support 4 as needed to adjust the height of the diffuse reflector 1. If the angle of the diffuse reflector 1 needs to be adjusted, rotate the diffuse reflector 1 around the pitch axis 2. During this process, the locking bolt 3 will slide in the semi-circular waisted groove structure. After adjustment, tighten the locking bolt 3 to fix the angle of the diffuse reflector 1.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
