Abstract

The invention discloses a video conference projection frame which comprises a base. A lifting assembly is installed on the base. A ball sleeve is fixed to the upper end of the lifting assembly. An adjusting ball is movably embedded in the ball sleeve. A connecting column is fixed to the adjusting ball. A fixed plate is installed at the tail end of the connecting column. A fixed frame and a movableframe are installed on the fixed plate. A second installation plate is fixed to the tail end of the fixed frame, a curtain box is fixedly installed on the second installation plate, and a multi-stageelastic telescopic rod is fixed to the lower tail end of the movable frame. The video conference projection frame is simple in structure and small in occupied space. The lifting assembly, the adjusting ball and the multi-stage elastic telescopic rod are respectively arranged, so that the height, any angle and flatness of the curtain are adjusted, the adjustment is free and flexible, the operationis simple and rapid, the use requirements of different places can be met, the frame can be folded and stored after being used, the storage, carrying and transportation are convenient, the structure is stable and reliable, and the projection effect is good.

Description

technical field [0001] The invention relates to the technical field of video conference auxiliary equipment, in particular to a video conference projection stand. Background technique [0002] The current video conferencing often uses projectors. The projectors are usually placed on the desktop or fixed on the indoor ceiling. In order to obtain better projection effects, the projection screen and the projector are generally used together. The projection screen is placed on the projection stand , and then point the projector to the screen to project. [0003] Existing projection stands are generally fixed on the wall. As the placement of the projector changes, its projection direction also changes. However, the fixed projection stand is not convenient for adjusting the angle and position of the screen, so it cannot Synchronous adjustment of the screen and the projector cannot ensure that the projection direction of the screen and the projector is always perpendicular, so tha...
