DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a rotating display device for an LED billboard. Figure 1-2A rotating display device for an LED billboard includes a base 1, a hollow block 2 is arranged at the upper end of the base 1, a sliding cavity 12 is arranged in the hollow block 2, a turntable 3 is arranged in the sliding cavity 12, a second rectangular cavity 9 is opened at the lower end of the turntable 3, a second motor 10 is installed at the inner top of the second rectangular cavity 9, an advertising board 6 is arranged above the base 1, and a display mechanism for the advertising board 6 is arranged above the base 1.

[0022] Reference Figure 1-2 The display mechanism includes a threaded rod 5 rotatably connected to the upper end of the turntable 3, and a mounting plate 14 is threadedly connected to the threaded rod 5. The upper end of the turntable 3 is fixedly connected to a guide rod 4, which passes through the mounting plate 14 and is slidably connected to the mounting plate 14. The end of the output shaft of the second motor 10 extends to the upper end of the turntable 3 and is fixedly connected to the lower end of the threaded rod 5.

[0023] After the second motor 10 is started, the threaded rod 5 is rotated, and then the mounting plate 14 threadedly connected thereto drives the advertising board 6 to move up or down, thereby achieving height adjustment.
