Abstract

The invention discloses projection equipment. The projection equipment comprises a box body, an exhibition assembly is installed in the box body, a part of the exhibition assembly is slidably connected with the box body, an overturning assembly is arranged in the exhibition assembly, and the top of the overturning assembly is in transmission connection with a projector; and the exhibition assembly enables the projector to slide out of the interior of the box body by pushing the overturning assembly, and the overturning assembly is used for adjusting the projection angle of the projector, thereby improving the film watching effect. According to the projection equipment, when a second worm rotates, a second worm gear is driven to perform responsive meshing rotation, and a rotating shaft of the second worm gear is fixedly connected with a base, so that the second worm gear drives the projector to deflect up and down through the base when rotating, thereby realizing angle adjustment when the projector watches a film; and the worm gear is in meshed connection with the worm so that the worm cannot be rotated by the worm gear due to the gravity of the projector, and the stability after the angle is adjusted is ensured.

Description

technical field [0001] The present invention relates to a projection device. Background technique [0002] The so-called teaching projector is also called micro projector, teacher projector, handheld projector, TRT-3M portable projector, mainly through 3MLCOSRGB three-color projection light machine and 720P chip decoding technology, the traditional huge projector is compact and portable , miniaturization, entertainment, and practicality, making projection technology closer to life and entertainment. The main working principle of the 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 to the display chip. The signal passes through the circuit system to achieve color scale and gray scale on the display chip to display the image, and then the projection lens at the front end of the projection will enlarge and project the image on the display chip to the corresponding screen.
