[0035] This utility model provides a technical solution:

[0036] Please see Figures 1-6 An auxiliary structure for installing an outdoor LED screen includes a base plate 1. Multiple casters 2 are mounted on the lower end of the base plate 1. A placement plate 3 is fixedly connected to the upper end of the base plate 1. A first clamping mechanism 4 is provided on the placement plate 3, which can clamp LED screens of different sizes and stably place them on the placement plate 3. A fixing plate 5 is fixedly connected to the upper end of the base plate 1. A lifting groove 6 is formed on one side wall of the fixing plate 5. A lifting plate 7 is slidably connected to the inner wall of the lifting groove 6. A second clamping mechanism 8 is provided on the lifting plate 7, which can clamp LED screens of different sizes for loading. The two sides of the lifting groove 6... A second threaded rod 9 is rotatably connected between the inner walls of the side, and a guide rod 10 is fixedly connected between the inner walls of the two sides of the lifting groove 6. One side of the lifting plate 7 is threadedly connected to the second threaded rod 9, and the other side is slidably connected to the guide rod 10. A third motor 11 is installed at the upper end of the fixed plate 5. The third motor 11 is a servo motor. The end of the output shaft of the third motor 11 extends into the interior of the lifting groove 6 and is fixedly connected to the upper end of the second threaded rod 9. The second threaded rod 9 is driven to rotate by the third motor 11, so that the lifting plate 7 slides up and down along the guide rod 10, thereby realizing the height adjustment of the second clamping mechanism 8, which can meet the needs of different installation heights.

[0037] Furthermore, the first clamping mechanism 4 includes a slide groove 41 formed on the upper end of the placement plate 3. A first threaded rod 42 is rotatably connected between the inner walls of the two sides of the slide groove 41. A first motor 43 is installed on the outer wall of the placement plate 3. The first motor 43 is a servo motor. The end of the output shaft of the first motor 43 extends into the slide groove 41 and is fixedly connected to one end of the first threaded rod 42.

[0038] Furthermore, the first threaded rod 42 is a bidirectional threaded rod, and both threaded ends are threadedly connected to sliders 44. The upper ends of the two sliders 44 are fixedly connected to sliding plates 45. Multiple U-shaped plates 46 are fixedly connected to the opposite sides of the two sliding plates 45. Sliding rods 47 are provided through the two side walls of each U-shaped plate 46. When the first motor 43 drives the first threaded rod 42 to rotate, the two sliders 44 will move relative to each other or away from each other, thereby adjusting the distance between the two sliding plates 45. This allows the first clamping mechanism 4 to adapt to LED screens of different sizes, enhancing the versatility of the equipment.

[0039] Furthermore, each pair of cooperating sliding rods 47 has a limiting block 48 fixedly connected to its opposite ends, and a first clamping plate 49 fixedly connected to the opposite ends of each pair of cooperating sliding rods 47. A spring 410 is sleeved on the outer wall of each sliding rod 47, and both ends of each spring 410 are elastically connected to the corresponding U-shaped plate 46 and limiting block 48 respectively. The spring 410 plays a buffering role. When clamping the LED screen, the spring 410 can prevent damage to the screen due to excessive clamping force. At the same time, the elasticity of the spring 410 can make the first clamping plate 49 fit tightly against the screen, ensuring the stability of the screen on the placement plate 3 and preventing shaking or displacement during movement or installation.

[0040] Furthermore, the second clamping mechanism 8 includes a mounting plate 81 fixedly connected to the upper end of the lifting plate 7. Two first electric telescopic rods 82 are installed on one side wall of the mounting plate 81. The telescopic ends of the two first electric telescopic rods 82 are fixedly connected to a movable box 83. Second electric telescopic rods 84 are installed on both inner walls of the movable box 83. Movable plates 85 are fixedly connected to the telescopic ends of the two second electric telescopic rods 84. Movable slots 86 are opened on opposite sides of the two movable plates 85. The first electric telescopic rods 82 can control the front and rear position of the movable box 83, and the second electric telescopic rods 84 can adjust the left and right position of the movable plates 85.

[0041] Furthermore, a second motor 87 is installed on the opposite sides of the two moving plates 85. The output shafts of the two second motors 87 extend into the corresponding moving slots 86 and are fixedly connected to gears 88. The inner walls of the two moving slots 86 are slidably connected to racks 89, and the two racks 89 mesh with the corresponding gears 88. The side walls of the two racks 89 are fixedly connected to second clamping plates 810. The transmission method between the gears 88 and the racks 89 enables the movement of the second clamping plates 810. The clamping force and position can be controlled according to the specific situation of the LED screen, which improves the stability and accuracy of the feeding process.

[0042] In practical use, the working principle of this utility model is as follows:

[0043] When the operator uses the device, the multiple casters 2 installed at the lower end of the base plate 1 allow the entire installation auxiliary structure to be easily moved in outdoor areas, making it convenient to adjust the position to a suitable installation location.

[0044] When the LED screen needs to be placed on the placement plate 3, the first motor 43 is started, causing the first threaded rod 42 to rotate, which in turn causes the two sliders 44 to move relative to or away from each other. By adjusting the distance between the two sliders 44, the distance between the two sliding plates 45 can be adjusted to accommodate LED screens of different specifications. When the sliding plates 45 move to the appropriate position, the LED screen is placed between the two sliding plates 45. At this time, the LED screen will push the first clamping plate 49, and the first clamping plate 49 will drive the sliding rod 47 to slide in the U-shaped plate 46, while compressing the spring 410. The elasticity of the spring 410 makes the first clamping plate 49 fit tightly against the LED screen, which not only provides a certain clamping force to ensure the stability of the LED screen on the placement plate 3, but also plays a buffering role to avoid damage to the screen due to excessive clamping force.

[0045] Then, according to the installation height requirements of the LED screen, the third motor 11 can be started to rotate the second threaded rod 9, thereby causing the lifting plate 7 to slide up and down along the guide rod 10, thus realizing the adjustment of the height of the second clamping mechanism 8 to meet the requirements of different installation heights.

[0046] Once the lifting plate 7 is adjusted to the appropriate height, the position of the moving box 83 is adjusted by controlling the extension and retraction of the first electric telescopic rod 82, bringing it closer to the LED screen. Then, the position of the moving plate 85 is adjusted by controlling the extension and retraction of the second electric telescopic rod 84, bringing it closer to both sides of the LED screen. Then, the second motor 87 is started, causing the gear 88 to rotate, which in turn causes the meshing rack 89 to drive the second clamping plate 810 to move, thereby clamping both sides of the LED screen. In this way, the clamping force and position can be controlled according to the specific situation of the LED screen, improving the stability and accuracy of the feeding process.

[0047] After the second clamping mechanism 8 clamps the LED screen, the LED screen can be lifted from the placement plate 3 and moved to the installation position for subsequent installation operations. After installation, the above steps are reversed to release the second clamping mechanism 8 and lower it to the initial position to prepare for the next installation task.

[0048] In summary, an outdoor LED screen installation auxiliary structure, by improving and optimizing its working principle, achieves adaptive clamping, flexible lifting, and loading operations for LED screens of different sizes. This effectively solves the problems of traditional installation methods being unable to handle diverse LED screen specifications and having low installation efficiency, thereby improving the overall quality and efficiency of outdoor LED screen installation.

[0049] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
