With the continuous development of the Internet, the way of meeting has evolved from traditional face-to-face discussions to remote meeting decisions through display screens. Therefore, conference display screens have become the main display equipment in conference rooms. Conference display screens were originally hung on the wall like TVs. In this way, the conference display screens cannot be moved according to the needs of the meeting, and when the position of the conference display screen needs to be changed, it is necessary to drill holes in the wall and reinstall it. Therefore, a support frame for conference display screens is needed to solve the above problems.

The two ends of the two tripods 1 71 are symmetrically fixed on one side of the support plate 6, and the two ends of the two tripods 2 72 are symmetrically fixed on the mounting plate 8 on the same side as the tripod 2 72. The tripod 1 71 and the tripod 2 72 are rotatably connected through the rotating shaft 73; the upper mounting seat 53 and the lower mounting seat 54 are both provided with through holes, and bearings 531 are embedded in the through holes. The threaded rod 55 is fixedly connected to the inner ring of the bearing 531.

[0024] In a specific implementation, the two tripods 72 are respectively arranged at the bottom lower edge and the top upper edge of the two tripods 1 71. The tripod 1 71 and the tripod 2 72 are fixedly connected by a rotating shaft 73 and the tripod 1 71 and the tripod 2 72 are rotated by the rotating shaft 73. During the rotation, the angle of the mounting plate 8 is adjusted relative to the support plate 6, and finally the display angle of the conference display screen installed on the mounting plate 8 is adjusted. The upper mounting seat 53 and the lower mounting seat 54 are both embedded with bearings 531 in the through holes. The bearings 531 can improve the smoothness of the rotation of the threaded rod 55, avoid a large load on the drive motor 51 when rotating the threaded rod 55, and extend the service life of the drive motor 51.
