Description

Technical Field

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

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues.

[0003] According to a Chinese patent application with patent number 202321134968.4, a dustproof projector includes a projector body and a remote control, wherein the remote control is movably mounted on the side of the projector body, a projector lens is fixedly mounted on the outside of the projector body for projection, a square column is fixedly mounted on the outside of the projector body, and the square column is used for fixed installation, a sealing plate is fixedly mounted on one side of the projector body close to the projector lens, and the sealing plate cooperates with a protective cover to seal and protect the projector lens, a T-shaped slide is provided in the square column, and the T-shaped slide is used to install a threaded rod to limit the threaded slider, and the T-shaped A threaded rod is rotatable in the slide, and the rotation of the threaded rod drives the threaded slider to move under the limit of the T-shaped slide. A threaded slider is provided on the threaded sleeve on the outer side of the threaded rod, and the threaded slider is movably clamped in the T-shaped slide. The movement of the threaded slider drives the movement of the protective cover, and a protective cover is fixedly provided on the outer side of the threaded slider. The protective cover is used to protect the projector lens and prevent the projector lens from being damaged. The projector lens can be protected by arranging structures such as the projector lens, square column, T-shaped slide, threaded slider, threaded rod and protective cover, thereby avoiding the problem of inconvenient maintenance caused by damage to the lens, thereby achieving the purpose of protecting the projector lens.

[0004] However, the projection direction of the dustproof projector is relatively fixed, and can only be adjusted by placing it in different directions. In addition, it often does not have the function of changing the projection direction in the vertical direction, which reduces the applicability of the dustproof projector. Therefore, we propose a multi-angle adjustable projector. Utility Model Content
