Abstract

The invention relates to the field of connecting components of video presenters, in particular to a folding-unfolding structure for a video presenter, which mainly comprises an armed lever, a main body and a rotating shaft, wherein the armed lever is connected with the main body through the rotating shaft; a bracket is arranged at one end of the rotating shaft, and an auxiliary bracket is arranged at the other end of the rotating shaft; a one-way bearing and a bearing sleeve are sleeved on the rotating shaft; the one-way bearing is pressed in the bearing sleeve; the bearing sleeve is connected and fixed with the armed lever through screws; and the bracket and the auxiliary bracket are fixedly connected with the main body. The invention has the beneficial effects that the structure of the invention can enable the video presenter to be folded or unfolded conveniently in the using process, larger torsion can be generated by applying proper force so that the armed lever can be unfolded easily, the video presenter can not turn, interfaces can not loose or fall, and the whole working process is relatively stable.

Description

technical field [0001] The present invention mainly relates to the field of link components of video display stands, and mainly relates to a folding-opening structure for video display stands. Background technique [0002] The use of the video display stand needs to open the arm bar, and the folded arm bar is stored in the podium when storing. Most of the traditional folding methods are controlled by friction. Excessive torque may easily cause the whole booth to flip when it is opened, causing the rear interface to loosen or fall off. Contents of the invention [0003] The present invention solves the above-mentioned shortcomings of the prior art, and provides a folding-opening structure for a video display stand that is easy to operate and stable in operation. [0004] The technical solution adopted by the present invention to solve the technical problems: the folding-opening structure for the video display stand mainly includes an arm, a main body and a rotating shaft, ...
