Description

Technical Field

[0001] The utility model relates to the technical field of ceiling-mounted projectors, and particularly relates to a ceiling-mounted projector with a selection structure. Background Technique

[0002] A projector is a device that can project images or videos onto a screen, and is widely used in families, offices, schools, and entertainment venues. Its installation method is mainly ceiling-mounted, and it needs to be used in conjunction with a ceiling-mounted projector during the installation process. A ceiling-mounted projector refers to installing a projector on the ceiling by hoisting to achieve a suspended display of the projection screen. This installation method is common in places such as conference rooms, classrooms, and lecture halls because it can provide a stable and wide-field-of-view projection environment. The advantages of ceiling-mounted projectors mainly include: wide field of view: Hoisting the projector can avoid interference from ground obstacles, enabling viewers to clearly see the projection screen from any position; space saving: Since the projector is installed on the ceiling, it does not need to occupy the space on the ground or desktop, making the entire space cleaner; stable picture: Hoisting the projector can ensure the stability of the projection screen by adjusting the brackets and hangers, reducing picture jitter caused by vibration or movement.

[0003] When installing a projector with the existing ceiling-mounted projector, it is relatively cumbersome, and usually only fixed models of projectors can be installed, with a relatively limited scope of application, and it is difficult to be used in conjunction with different projectors.
