[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a stabilizing support device for an anti-shaking movable background board, comprising a main body plate 1 and a handle 16. Two stainless steel limiting plates a2 are fixedly connected to the rear side of the main body plate 1 via welding. The inner walls of the two limiting plates a2 are polished to form smooth sliding tracks. Limiting posts a3 are slidably connected within the tracks. The outer walls of these posts are smooth and highly wear-resistant, effectively reducing frictional resistance during sliding. A support plate 4, also made of aluminum alloy, is slidably connected to the outer wall of the limiting posts a3. High-precision grooves are designed on both sides of the support plate 4, with wear-resistant nylon bushings embedded inside. Limiting posts b5 are slidably connected within the bushings, and adjustable angled support rods 6 are slidably connected to their outer walls. The ends of the support rods are chamfered to avoid stress concentration. The outer walls of the support rods are coated with an anti-slip rubber coating to enhance grip stability. One end of the angled support rod 6 is connected to a limiting post c7 via a sliding fit. Both ends of the support rod have limiting discs with a diameter larger than the main body to prevent detachment. The outer wall of the limiting post c7 is simultaneously connected to the limiting buckle a8 and the limiting buckle b9. The top of the support plate 4 has a semi-circular groove 10. The inner wall of the groove 10 is polished to match the sliding trajectory of the limiting post a3. The end of the support plate 4 near the main plate 1 is designed with a chamfer to avoid scratching during installation. The two ends of the inclined support rod 6 are chamfered to effectively disperse stress. The outer wall of the support plate 4 is slidably connected to the pin 11 with spring return function. The pin 11 is simultaneously slidably connected in the pre-set positioning hole of the inclined support rod 6. When the device is unfolded, the inclined support rod 6 can be quickly locked by the cooperation of the pin 11 and the positioning hole. The entire device, through the multi-stage sliding limiting structure and the adjustable support angle of the inclined support rod 6, can effectively counteract the shaking of the background plate caused by wind or human touch. At the same time, the handle 16 adopts an ergonomically designed non-slip rubber-wrapped structure, which is not only easy to carry but can also be used as a temporary adjustment fulcrum. It achieves a balance between lightweight and ease of operation while ensuring structural strength.

[0013] Reference Figure 1 , Figure 3 , Figure 5The inner walls of both sides of the main body plate 1 form symmetrically distributed dovetail groove sliding tracks, with slide rails embedded in the tracks and extension plates 12 slidably connected to them. The extension plates 12 have high-precision straight-tooth racks machined inside using a cutting process, and the rack surfaces are treated to improve wear resistance, forming an integral modular structure with the extension plates 12. The handle 16 is made of engineering plastic injection molding, with a mirror-polished surface and ergonomically designed chamfers. The grip area is covered with an anti-slip silicone sleeve. A connecting rod 15 is threadedly fastened to the rear of the handle 16, and is slidably connected to the pre-set guide rails on the main body plate 1 via two sets of bushings. Inside the hole, a gear 14 is fixed to the rear end of the connecting rod 15. The outer wall of the gear 14 and the rack of the extension plate 12 form a meshing transmission pair. When the handle 16 is rotated, the synchronous linear displacement of the two extension plates 12 can be achieved through the rack and pinion transmission of the gear 14. It also has a self-locking function at any position. The device as a whole, through this composite structure of precision gear 14 transmission and high-rigidity sliding guide rail, not only ensures the accuracy and stability of width adjustment, but also improves the operating comfort through the anti-slip chamfer design of the engineering plastic handle 16. It achieves rapid size adaptation while ensuring the structural rigidity of the background plate support system.

[0014] Working principle: The main plate 1 serves as the core load-bearing structure. Two stainless steel limiting plates a2 welded to its rear side form a vertical sliding track. The chrome-plated steel limiting post a3 embedded in the track and the semi-circular groove 10 on the top of the aluminum alloy support plate 4 form a sliding pair, allowing the support plate 4 to be vertically adjusted along the main plate 1. Limiting posts b5 are embedded in the grooves on both sides of the support plate 4. The limiting post b5 cooperates with the sliding hole at the lower end of the inclined support rod 6 to form an adjustable angle support structure. The upper end of the inclined support rod 6 is connected to the limiting buckle a8 and the limiting buckle b9 respectively through the limiting post c7. The limiting buckle a8 uses an engineering plastic buckle with a self-locking function to achieve basic positioning. When the support needs to be extended, the operator rotates the handle 16 with the chamfered anti-slip treatment, which drives the connecting rod 15 on its rear side to rotate synchronously. The gear 14 fixed at the rear end meshes with the rack embedded in the extension plate 12, driving the aluminum alloy extension plates 12 and the fixed plate 13 on both sides to extend synchronously and linearly along the inner wall of the main plate 1. After adjustment, the spring steel pin 11 on the outer wall of the support plate 4 is inserted into the pre-set positioning hole of the diagonal support rod 6 to achieve mechanical locking. At this time, the limiting discs at both ends of the limiting post a3, limiting post b5, and limiting post c7 prevent the connecting parts from coming off. The chamfered design at both ends of the diagonal support rod 6 effectively disperses stress, and the chamfered end of the support plate 4 near the main plate 1 avoids installation interference. The entire device achieves adaptive adjustment of the background plate within a certain width range through the coordinated action of the multi-stage sliding limiting mechanism and the gear 14 rack and pinion transmission system. Through the triangular support structure of the diagonal support rod 6 and the multi-point limiting mechanism, the lateral swaying torque is effectively counteracted, ensuring that the background plate maintains vertical stability under wind load or human touch.
