Description

Technical Field

[0001] The utility model relates to the technical field of folding brackets, in particular to a folding bracket for a box-type live broadcast machine. Background Art

[0002] A box-type live broadcast machine is a computer mainframe specially designed for live broadcast purposes. Usually, it integrates devices such as a mainframe, a display, and a camera in a box for easy carrying and use. It generally consists of a box body and electronic components such as a mainframe display that are arranged inside the box body and connected to the box body as a whole. Since the display screen needs to be adjusted according to different usage angles during use, and the display screen is connected to the box body, it is impossible to perform operations such as tilting forward and backward and switching between horizontal and vertical screens for the angle adjustment of the display screen as required. Instead, it is necessary to use the movement adjustment of the box body to achieve different angle adjustments, which brings certain inconvenience to the operation of the display screen;

[0003] Therefore, the utility model provides a folding bracket for a box-type live broadcast machine that facilitates the adjustment of the display screen angle. Summary of the Utility Model
