Abstract

The invention discloses a lens adjusting device which comprises a light machine shell, a lens bracket and a sliding adjuster. The sliding adjuster includes at least two horizontal adjusting rods, at least two vertical adjusting rods, at least two horizontal rails parallel to each other and at least two vertical sliding rails parallel to each other. Each of the horizontal rails is equipped with a horizontal adjusting rod, and each of the vertical sliding rails is equipped with at least one vertical adjusting rod. One end of each of the horizontal adjusting rod is fixedly installed at a side wall of one side of the lens bracket, and the other end is fixedly installed to a side wall of the other side of the lens bracket. One end of each of the vertical adjusting rod is fixedly installed at a top wall of the light machine shell, and the other end is fixedly installed to the bottom wall of the light machine shell. When the lens adjusting device is used to adjust a deviation between a lens and a digital micro mirror device of an optical engine, the lens adjusting device can not deflect by itself, the adjusting precision is more accurate, and the applicability is better.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a lens adjusting device. Background technique [0002] After the optical engine of the projector is assembled with the lens, an offset phenomenon usually occurs, that is, the center of the lens is offset from the center of the digital micromirror device (DMD, Digital Micromirror Device) of the optical engine. [0003] In the prior art, for the deviation phenomenon between the lens of the projector and the digital micromirror device of the optical engine, a common solution is to set a lens adjustment device between the lens of the projector and the digital micromirror device of the optical engine , through the lens adjustment device, adjust the relative position between the lens and the digital micromirror device of the optical engine in the horizontal direction and the vertical direction, thereby eliminating the deviation phenomenon between the lens and the digital micromirror...
