Multi-angle free adjustment projector for film and television media

Abstract

The invention discloses a multi-angle free adjustment projector for film and television media, and relates to the technical field of projectors, the multi-angle free adjustment projector comprises a projector body and a supporting rod, the interior of the supporting rod is coaxially connected with a rotation adjusting rod, the bottom end of the supporting rod is provided with a mounting disc, and the bottom end of the rotation adjusting rod penetrates through the mounting disc and is hinged to the projector body; the supporting rod is slidably sleeved with a limiting sleeve, the bottom end of the limiting sleeve is provided with a limiting gear ring, the top end of the mounting disc is provided with an annular tooth groove, the mounting disc is provided with a plurality of penetrating holes at intervals in the circumferential direction, sliding rods slidably penetrate through the penetrating holes, sliding blocks are hinged to the bottom ends of the sliding rods, and the sliding blocks are in sliding fit with the projector body. The supporting rod is sleeved with an elastic abutting ring, a driving sleeve is arranged on the supporting rod, and when the driving sleeve drives the limiting tooth ring to abut against the annular tooth groove, the elastic abutting ring abuts against the side wall of the sliding rod. According to the projector, the projection angle of the projector can be adjusted at multiple angles, so that the projector can be conveniently installed.

Description

technical field [0001] The present application relates to the technical field of projectors, in particular to a multi-angle freely adjustable projector for film and television media. Background technique [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 a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. It is widely used in homes, offices, schools and entertainment venues. [0003] Such as figure 1 As shown, when the existing projector is in use, a support rod 2 is usually fixedly connected to the top of the projector housing, the top of the support rod 2 is provided with a fixing seat 23, and the fixing seat 23 is installed on the ceiling through an expansion bolt 24. Then fix the screen on the wall so that the image output by the projector can be projected onto the screen. [0004] However, the angle of the projector after...

Problems solved by technology

[0004] However, the angle of the projector after installation is prone to deviation, and it is difficult to ensure that the image projected by the projector completely coincides with the screen. Drill holes in the ceiling and install expansion bolts, making it difficult to install the projector
