Description

Technical Field

[0001] The utility model relates to the technical field of projector brackets, in particular to a projector bracket capable of remote calibration. Background Art

[0002] A projector stand is a device used to mount and support a projector. It is usually made of metal or plastic and has a stable structure and adjustable functions. The projector stand can be installed on a wall, ceiling or other flat surface to place the projector in a suitable position and adjust the angle and height of the projector to obtain the best projection effect. It usually has foldable and tiltable functions to meet different projection needs. It can effectively fix the projector, provide a stable projection platform, and reduce the shaking and vibration of the projector, thereby improving the projection quality.

[0003] However, some existing projector brackets usually require manual assistance when adjusting, so after the adjustment is completed, the angle of the projector needs to be calibrated. Because manual assistance is required, remote adjustment cannot be achieved, which makes the bracket more cumbersome to use. Therefore, this problem needs to be solved. Utility Model Content
