Furthermore, the lack of a stable angle locking structure makes the curved screen prone to angle displacement due to external forces after installation, affecting the display effect. In addition, the fasteners are in direct rigid contact with the LED display unit during installation, which can easily cause scratches or damage to the surface of the display unit. Moreover, it is difficult to accurately adjust the position of each unit when multiple units are combined for installation, resulting in uneven splicing of the curved screen. Utility Model Content

The guide rail 300 has a guide groove 330 on its top. The slide block 340 is slidably connected to the inner wall of the guide groove 330. The rear inner wall of the guide groove 330 is rotatably connected to a lead screw through a bearing. 360. The outer wall of the lead screw 360 is threaded to the inner wall of the slide 340 to control the extension and retraction of the slide 340 in the guide groove 330. The outer wall of the mounting plate 350 is fixedly installed by embedding the protective pad 351 through a recess. The thickness of the protective pad 351 is greater than the depth of the recess in the inner wall of the mounting plate 350. The inner walls of the mounting plate 350 and the protective pad 351 are provided with rounded rectangular grooves 352. The rounded rectangular grooves 352 are used to detachably fix the LED display unit with bolts. Several LED display units are combined to form an arc screen.

[0022] The specific application scenario of this embodiment is as follows: The smooth rotating block 310 on the outer wall of the rear end of the guide rail 300 is fitted onto the outer wall of the rotating shaft 230, allowing the guide rail 300 to rotate around the rotating shaft 230 via the smooth rotating block 310, thereby achieving secondary angle fine-tuning to meet the more precise curvature requirements of the curved screen; after the fine-tuning is completed, the second locking screw 320 on the inner wall of the rear end of the smooth rotating block 310 is tightened, so that the end of the second locking screw 320 abuts against the outer wall of the rotating shaft 230, locking the position of the smooth rotating block 310, thereby fixing the angle of the guide rail 300; the inner wall of the rear end of the rotating guide groove 330 is connected to the screw 360 mounted on the bearing, and the outer wall of the screw 360 is threadedly engaged with the inner wall of the slide block 340.
