Abstract

The invention discloses a projector placement device and relates to the technical field of projector accessories. The placement device of the projector includes a base, fixed rods are fixedly installed on both sides of the top of the base, a slide bar is fixedly installed between the corresponding sides of the two fixed rods, and a hydraulic cylinder is fixedly installed at the bottom end of the slide rod. The surface of the rod is slidingly sleeved with a first slider, and the side of the first slider close to the corresponding fixed rod is fixedly connected with the output end of the hydraulic cylinder; the top of the first slider is rotatably connected with a first rotating rod; two The side corresponding to the fixed rod is slidingly connected with a second slider, and a lifting plate is fixedly installed between the two second sliders; a motor box is fixedly installed on the bottom of the lifting plate; the rotation of the motor drives the rotation of the threaded rod , so that the first threaded block and the second threaded block are close together, and the lifter is driven up and down by the lifting rod, so that the level of the projector can be quickly adjusted, which is convenient for use.

Description

technical field [0001] The invention relates to the technical field of projector accessories, in particular to a projector placement device. 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; There are three liquid crystal panels in the projector, in which liquid crystals are distributed; the liquid crystals are substances between liquids and solids, which do not emit light by themselves. They are arranged neatly like the pixels on the fluorescent screen; the projector uses the The photoelectric effect, that is, the arrangement of the liquid crystal molecules and the state of the liquid crystal molecules themselves change under the action of the electric field, which affects the light transmittance or reflectivity of the liquid crystal cell. Using this prin...
