[0018] The present invention is further configured such that the lifting assembly includes a support tube fixed to the top of the movable seat, the top of the support tube has a telescopic hole, the inner wall of the telescopic hole is slidably connected to a telescopic rod, the top of the telescopic rod is connected to the bottom of the mounting plate, and the support tube is connected to the telescopic rod through a fixing mechanism.

[0019] The above technical solution improves the convenience of adjusting the height of the mounting frame by adjusting the height of the telescopic rod inside the support tube when the height of the telescopic rod needs to be adjusted, and locking the telescopic rod with a fixing mechanism after the height of the telescopic rod is adjusted.

[0020] The present invention is further configured such that the fixing mechanism includes a threaded hole with a support tube outer wall, the inner wall of the threaded hole is connected to a fixing bolt by a thread, and the outer wall of the telescopic rod is provided with a plurality of equally spaced limiting grooves, and the fixing bolt can enter into the limiting grooves.

[0021] With the above technical solution, after the height of the telescopic rod is adjusted, the fixing bolt can be turned by hand and will enter the corresponding limit groove, which improves the convenience of fixing the telescopic rod.

[0022] The beneficial effects of this utility model are as follows:

[0023] This LED screen mounting bracket works by placing the LED screen into the support frame. Once the LED screen is fully inserted, the control motor drives the lead screw to rotate, which in turn moves the pressure plate downwards. The pressure plate presses and secures the LED screen from the top, providing a good fixing effect. At the same time, the support frame protects the LED screen from the edges, preventing damage from bumps and impacts and extending the lifespan of the LED screen.

[0024] The LED screen mounting bracket allows for height adjustment. When the height of the mounting bracket needs to be adjusted, the height of the telescopic rod inside the support tube is adjusted. After the height of the telescopic rod is adjusted, the fixing mechanism locks the telescopic rod in place, improving the convenience of adjusting the height of the mounting bracket. After the height of the telescopic rod is adjusted, the fixing bolt can be turned by hand, and the fixing bolt can be turned into the corresponding limit groove, improving the convenience of fixing the telescopic rod.
