Problems solved by technology

However, in some cases, due to problems such as the hanger, the building or the projector itself, it may be necessary to adjust the tilt angle of the projector in the horizontal direction. The existing hanger cannot achieve such a function, which may affect the projection The effect has a certain impact, especially in the occasions that require high projection clarity, the existing projector hanger can no longer meet the needs

Description

technical field [0001] The invention belongs to the technical field of projection auxiliary equipment, and relates to a projector hanger. Background technique [0002] A projector is an electronic device that can project video or images onto a screen. It has been widely used in school classrooms, conference rooms, entertainment venues and home theaters to project various flat projections. In order to facilitate the fixing of the projector and have a better projection effect, it is generally fixed on the ceiling by a projector hanger. [0003] At present, the existing hangers for fixing the projector can only adjust the height of the projector, and some can adjust the distance between the projector and the screen. However, in some cases, due to problems such as the hanger, the building or the projector itself, it may be necessary to adjust the tilt angle of the projector in the horizontal direction. The existing hanger cannot achieve such a function, which may affect the pro...
