[0002] The LED display screen is an electronic display screen composed of LED dot matrices. It changes the screen display content form such as text, animation, pictures, and videos in a timely manner by turning on and off red and green light beads, and controls the component display through a modular structure. At present, the application scenarios of LED display screens are becoming more and more extensive. Many occasions that need to display information, such as government halls, outdoor advertisements, and large exhibition halls, will install large LED display screens. Therefore, it is necessary to use a mounting structure to install the LED display screen.

When the front clamping piece and the rear clamping piece are connected together to fix the LED display screen, the fixed block and the sliding block are decomposed and inserted into the sliding grooves on the front clamping piece and the rear clamping piece. At this time, the tension spring and the stopper cooperate to limit the limit block in the fixed groove. When fixing the LED display screen, the fixed block and the sliding block are directly inserted into the front clamping piece and the rear clamping piece. By pulling the sliding block, the distance between the sliding block and the fixed block can be changed, which is convenient for fixing LED display screens of different thicknesses.

[0004] With respect to the above-mentioned disclosed patent content, a plurality of adjustment slots and adjustment bolts are provided. When the LED display screen needs to be installed, a plurality of adjustment bolts need to be rotated to achieve the purpose of fixing the fixed block and the sliding block through the adjustment bolts, and then the installation and fixation of the LED display screen can be completed.

[0038] Specifically, a driving gear 404 is sleeved on the upper and lower parts of the outer walls of the first rotating shaft 401 and the second rotating shaft 410, a driving sprocket 411 is sleeved on the lower part of the outer wall of the first rotating shaft 401, a driven sprocket 413 is sleeved on the lower part of the outer wall of the second rotating shaft 410, and a chain 412 is meshed and connected between the driven sprocket 413 and the driving sprocket 411. When the first rotating shaft 401 rotates, it drives the driving sprocket 411 to rotate, and then drives the chain 412 to rotate, and the chain 412 drives the driven sprocket 413 rotates, the threaded column 409 is threadedly connected with the threaded groove 407, and the movable shaft 406 is rotatably connected with the frame 1 through the bearing. When the movable shaft 406 rotates, it will drive the threaded groove 407 to rotate, thereby making the threaded column 409 move, and the threaded column 409 drives the card plate 415 to move, and the through port 414 is adapted to the card plate 415. The side of the card plate 415 is in a "concave" shape. The setting of the through port 414 is convenient for accommodating the card plate 415, and the card plate 415 can clamp and fix the LED display screen.
