Abstract

The embodiment of the invention discloses a projection device. The projection device comprises a ray machine main body, a lens assembly, a fastener and a spring, the ray machine main body is provided with a first mounting surface, and a first through hole is formed in the first mounting surface; the lens assembly is detachably connected with the ray machine main body; the lens assembly is provided with a second mounting surface, and a second through hole is formed in the second mounting surface; the maximum width of the cross section of the fastener is smaller than the minimum aperture of the cross section of the second through hole, and the fastener can move in the second through hole. One technical effect of the embodiment of the invention is that the structural design is reasonable, the position of the lens assembly relative to the ray machine main body can be effectively adjusted, the assembly error is reduced, and the picture quality of a projected image is improved.

Description

technical field [0001] The present application belongs to the technical field of electronic products, and in particular, the present application relates to a projection device. Background technique [0002] With the development of projection technology, the development direction of projectors is gradually moving towards the direction of miniaturization and portability, thus the miniature projector was born. The micro projector is closer to life and entertainment. The working principle of the micro projector is to emit light from the light source. Through a series of optical lighting systems, the light from the light source is evenly irradiated on the display chip, and the signal passes through the circuit system on the display chip. The color scale and gray scale are realized, and the image is displayed. After that, the projection lens on the front end of the projection will enlarge and project the image on the display chip to the corresponding screen. [0003] The current ...
