Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: be applied to LED display screen of brightening engineering, including LED display screen body 5, still include frame 1, frame 1's lower table wall is equipped with semicircle-shaped lug 14, lug 14's bottom is equipped with mounting panel 4, lug 14 is connected through the round pin axle rotation with mounting panel 4, LED display screen body 5 is fixed on mounting panel 4's lateral wall, frame 1's inner chamber is equipped with slide bar 13 on the horizontal direction and slide bar 13's outside cover and is equipped with between slide sleeve 8 and the mounting panel 4 through connecting rod 3 swing joint, slide sleeve 8 is sliding fit with slide bar 13, the both ends of connecting rod 3 respectively with slide sleeve 8 and mounting panel 4 normal running fit, slide sleeve 8's top is equipped with gear 7, be fixed with drive gear 7 pivoted motor 2 on frame 1's the outer wall.

Specifically, as shown in fig. 1, the outer wall of the protruding block 14 is provided with scale lines 6, the scale lines 6 are distributed at equal angles around the center of the protruding block 14, and the rotation angle of the mounting plate 4 can be observed through the scale lines 6.
