Technical Field

[0001] The utility model relates to the technical field of projectors, in particular to an angle-adjustable bracket for a projector. Background Art

[0002] A projector is a device that can project images or videos onto a screen or wall. It is usually used for demonstrations, teaching, entertainment, and other occasions where images need to be displayed to multiple people.

[0003] A projector can be connected to a computer, DVD player, TV, etc. to play a variety of content.

[0004] According to different projection technologies, projectors can be divided into liquid crystal projectors (LCD), digital light processing projectors (DLP) and laser projectors.

[0010] Flexibility: The projector can adjust the screen size and position as needed, flexibly adapting to different viewing environments.

[0011] At present, when a projector is in use, since it needs to be adjusted according to the projection position, most of the projectors cannot adjust the pitch angle autonomously, resulting in the projection height of the projector being too high or too low, causing discomfort to the viewer. At the same time, since the projector will be suspended on the ceiling or placed on a table when in use, it is necessary to design a mechanism that can adjust the pitch angle of the projector while facilitating multiple installations.
