[0030] Embodiment one

[0031] In combination with the drawings, a UV spray printing LED multimedia billboard is shown, which comprises a pedestal 1. In order to facilitate the adjustment of the height of the display screen 9, a lifting frame 5 is connected to the two screw rods 4 in a threaded manner. Figure 1 In combination with the drawings, a UV spray printing LED multimedia billboard is shown, which comprises a pedestal 1. In order to facilitate the adjustment of the height of the display screen 9, a lifting frame 5 is connected to the two screw rods 4 in a threaded manner. Figure 1 and Figure 2 As shown in the drawings, the following structure is adopted. The pedestal 1 is provided with a stand 3 symmetrically left and right. A screw rod 4 is rotatably arranged in the stand 3. A lifting frame 5 is threadedly connected to the two screw rods 4. A power assembly for driving the two screw rods 4 to rotate at the same frequency is arranged in the pedestal 1. An equipment cavity 10 is arranged in the pedestal 1. The power assembly is arranged in the equipment cavity 10. One end of each of the two screw rods 4 extends into the equipment cavity 10 and is rotatably connected to the bottom of the equipment cavity 10. The power assembly comprises a motor 11 fixedly arranged in the equipment cavity 10. A rotating shaft is connected to the output end of the motor 11. A driving sprocket 12 is sequentially arranged on the rotating shaft. A driven sprocket 13 is fixedly arranged on the screw rod 4. The driving sprocket 12 is connected to the driven sprocket 13 through a synchronous belt 14. ​

[0032] The motor 11 drives the active synchronous pulley 12 to rotate, and under the transmission of the synchronous belt 14, the two lead screws 4 rotate at the same frequency. The lead screws 4 cooperate with the lifting frame 5 to realize the adjustment of the height of the lifting frame 5. When the lead screw 4 rotates forward, the lifting frame 5 rises; conversely, when the lead screw 4 rotates backward, the lifting frame 5 descends.

[0033] In outdoor or brightly lit environments, the display screen 9 may be affected by sunlight or other light sources, thus impacting the display effect. To avoid this and improve the device's usability, in conjunction with the attached... Figure 3 , Figures 5 to 7 As shown, the structure is as follows: Sliding members 7 are symmetrically connected inside the lifting frame 5; a mounting frame 8 is rotatably mounted on the sliding member 7; a display screen 9 is inserted into the mounting frame 8; one end of the rotating shaft of the mounting frame 8 passes through the sliding member 7 and is connected to a rotating member 18; a positioning rod 19 is inserted into the rotating member 18; several positioning grooves 20 are arranged circumferentially on the side of the rotating member 18; a sliding groove 21 is provided inside the rotating member 18; a push plate 22 is provided on the positioning rod 19; the push plate 22 slides within the sliding groove 21; a spring 23 is sleeved on the outside of the positioning rod 19; one end of the spring 23 is connected to the push plate 22, and the other end is connected to the inner wall of the sliding groove 21.

[0034] When the angle of the display screen 9 needs to be adjusted, pull the positioning rod 19 out of the positioning groove 20, rotate the rotating part 18 to the required angle, and then the positioning rod 19 is reinserted into the corresponding positioning groove 20 under the action of the spring 23 to fix the adjusted angle position and ensure the stability of use.
