Radian adjustment mechanism and display screen

Abstract

[Problem] This invention provides a radian adjustment mechanism and a display screen. [Solution] The display screen includes a radian adjustment mechanism, which includes a first unit, a second unit, a rack assembly, a gear assembly, and a drive rod. The first unit includes a first part and a second part, and the second unit includes a third part and a fourth part. The first part and the third part are slidably connected, and the second part and the fourth part are slidably connected. The rack assembly includes a first rack, which is fixed to the first part. The gear assembly includes a first gear, which meshes with the first rack. The drive rod is fixedly connected to the first gear, and the drive rod is rotatably connected to the third and fourth parts. When adjusting the radian of the display screen, simply rotating the drive rod drives the first gear to rotate, and the rotation of the first gear drives the first rack to slide relative to the second unit. The meshing of the gear and the rack allows the radian of the display screen to be adjusted with a 1-degree accuracy.
