[0002] Currently, when LED display screens are used outdoors, the bottom adjustment device is designed with wheels, and users can adjust the position of the display screen by moving the wheels. Specifically, these wheels are usually installed on the bottom bracket or base, and users can simply push or pull the wheels to change the position of the display screen, thereby achieving the purpose of convenient movement, positioning and position adjustment.

[0003] The existing LED bottom adjustment device is used to adjust the position of the LED display screen at its upper end through the bottom universal wheel group. However, when used outdoors, the ground is uneven. When the universal wheel slides over, the uneven ground will cause the universal wheel to be unable to slide smoothly, and the LED display screen will shake or tilt, which may cause damage or loosening of the internal components of the screen, thereby affecting the display effect and the life of the equipment. Therefore, it is necessary to redesign a bottom adjustment device for the LED display screen to address the above problems. Utility Model Content

[0021] With the help of the elastic properties of the spring 9 itself and the sliding of the piston 10, when the base 1 is pushed to slide, it can effectively buffer the force from the bumpy road section, absorb and transfer the impact force caused by the ground vibration, thereby reducing the shock and vibration transmitted to the LED display.

[0022] Reference Figure 2 and Figure 3 The upper end surface of the base 1 is fixedly connected to a frame 5, a slider 13 is slidably connected inside the frame 5, the outer walls on both sides of the slider 13 are fixedly connected to connecting rods 6, and a fixing plate 8 is installed at the end of the connecting rod 6.
