[0002] As the name implies, a radiographic plate light and shadow prop is a prop used to create light and shadow effects in photography or film shooting. These props usually have specific shapes, materials, and colors, and can reflect, refract, or absorb light, thus forming unique light and shadow effects on the shooting object. By adjusting the position, angle, and intensity of the light source of the radiographic plate, the photographer can flexibly control the light and shadow distribution of the picture and create the desired atmosphere and visual effect.
[0003] The adjustable support frame for radiographic plate light and shadow props plays a crucial role in photography and film production. It can flexibly adjust the position, angle, and height of the radiographic plate or light and shadow prop to adapt to different shooting requirements and scene changes. In the prior art, an adjusting rod, a clamping structure, and a fixing plate are arranged at the top of the support frame, and the radiographic plate is fixed on the fixing plate through the clamping structure.
[0004] However, the clamping structure in the prior art only clamps and fixes the radiographic plate through the mutual cooperation between the clip and the tape. During the use process, it is not easy to adjust the position of the radiographic plate, and the position of the clamping structure is fixed and cannot be flexibly changed according to the size of the radiographic plate, so the flexibility of the support frame for the radiographic plate is poor. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0030] The embodiments of the present utility model will be described below according to its overall structure.
[0031] An adjustable bracket adaptable to fixing contrast plates of different sizes, as Figures 1-5 shown, includes a support rod 1. A plurality of adjusting rods 3 are provided at the top of the support rod 1. The end of the adjusting rod 3 is rotatably connected to a connecting plate 4. One side of the connecting plate 4 is fixedly connected to a connecting rod 5. The end of the connecting rod 5 is fixedly connected to a fixing block 6. A fixing frame 8 is arranged in the fixing block 6. A first movable block 12 and a second movable block 24 are movably connected in the fixing frame 8. Convex blocks 16 are fixedly connected to both ends of the second movable block 24. A first rack 17 is fixedly connected to one side of the convex block 16. A second rack 18 is fixedly connected to the inner side of the first movable block 12. The first rack 17 and the second rack 18 are parallel to each other. A gear 20 is arranged between the first rack 17 and the second rack 18. The convex block 16, the first rack 17 and the second rack 18 are located inside the fixing frame 8. A pressing plate 11 is rotatably connected to the tops of the first movable block 12 and the second movable block 24. A magnetic attraction structure is filled in the first movable block 12, the second movable block 24 and the pressing plate 11. A rotating shaft 19 is arranged between the pressing plate 11, the first movable block 12 and the second movable block 24. Torsion springs are arranged at both ends of the rotating shaft 19.
[0032] During use, the whole device is erected on the ground through the support rod 1 for use. The height of the bracket can be adjusted through a plurality of adjusting rods 3. Then, the fixing frame 8 is fixed in the fixing block 6. When it is necessary to clamp the contrast plate, by rotating the gear 20, the rotation of the gear 20 drives the first rack 17 and the second rack 18 to move, thereby pushing the first movable block 12 and the second movable block 24 to slide in the fixing frame 8 until it can be adapted to the contrast plate to be clamped. With this structure, flexible adjustment can be made according to the size of the contrast plate. Then, the pressing plate 11 is turned over and the contrast plate is placed on the first movable block 12 and the second movable block 24. Through the rotating shaft 19, the torsion springs and the magnetic attraction structure on the pressing plate 11, the pressing plate 11 can clamp the contrast plate. The transmission mode of the gear 20 and the rack ensures the stability and accuracy of the adjustment process, reduces potential safety hazards caused by component loosening or dislocation. The introduction of the magnetic attraction structure and the torsion springs further enhances the fixing effect and improves the stability of the overall structure. With this structure, it is beneficial to solve the technical problems that the existing clamping structure has a single way of fixing the contrast plate, inconvenient adjustment, and lack of flexibility to adapt to contrast plates of different sizes, resulting in poor overall flexibility of the bracket, and can improve the practicability and flexibility of the entire adjustable bracket applicable to fixing contrast plates.
[0033] The further cooperation between the adjusting disc 10 and the gear 20 is conducive to flexibly rotating the gear 20 between the first rack 17 and the second rack 18, thereby driving the first rack 17 and the second rack 18 to move within the fixed frame 8. The cooperation between the provided limiting block 9 and the limiting rod 15 requires pulling the limiting block 9 and the limiting rod 15 upward when rotating the adjusting disc 10, and then the positions of the first movable block 12 and the second movable block 24 within the fixed frame 8 can be adjusted by rotating the adjusting disc 10. After the positions of the first movable block 12 and the second movable block 24 are determined, the limiting block 9 and the limiting rod 15 are pressed downward to make the first card slot 14 catch on the outside of the adjusting disc 10. With this structure, the adjusting disc 10 can achieve a self-locking effect. The provided second movable slot 22 is conducive to enabling the gear 20 and the limiting rod 15 to move flexibly within the fixed frame 8 and is used in conjunction with the adjusting disc 10 and the limiting block 9.
[0034] In this embodiment, the provided first movable slot 21 is conducive to enabling the second rack 18 not to be restricted by the convex block 16 when the first rack 17 and the second rack 18 move relatively, enabling the second rack 18 to pass through the first movable slot 21, so that the first rack 17 and the second rack 18 can move flexibly. The provided second card slot 23 is conducive to flexibly clamping the fixed frame 8 within the fixed block 6, and the fixed frame 8 and the fixed block 6 can be connected and fixed through the fixing bolt 7, which is more convenient for installation and disassembly. The provided base 2 can make the support rod 1 more stable and not prone to shaking. The design of the sliding slot 13 allows the convex block 16, the first rack 17, and the second rack 18 to freely slide or adjust their positions within a certain range, thereby increasing the flexibility of the structure.
