The invention belongs to the technical field of projectors, and particularly relates to an Internet of Things based teaching projector, comprising a fixed rod and a mounting plate; a wind-up roll anda guide roll are sequentially arranged at the top of the mounting plate from left to right, and a motor I for driving the wind-up roll is arranged behind the wind-up roll; two fixed plates are symmetrically arranged at the front and back below the mounting plate, a plurality of groups of guide rods are arranged at the right upper side of the fixed plate, an upper sealing plate and a lower sealingplate are arranged between the two fixed plates, a chute I is arranged on the left wall of the lower sealing plate; an elastic metal strap is wound on the wind-up roll, a rack plate is connected to the other end of a chute II, and a connecting shaft mounts the projector body between the fixed plate; teeth meshed with the rack plate are formed at the right end of the projector main body; a wind-upshaft is arranged on the left wall of the upper sealing plate, a steel wire rope is wound on the wind-up shaft, and the other end of the steel wire rope is connected to the right upper end of the projector main body.
Description
technical field [0001] The invention belongs to the technical field of projectors, in particular to a teaching projector based on the Internet of Things. Background technique [0002] The so-called teaching projector is also known as miniature projector, teacher projector, handheld projector, TRT-3M portable projector, mainly through 3M LCOS RGB three-color projection light machine and 720P chip decoding technology, the traditional huge projector is refined, Portability, miniaturization, entertainment, and practicality make projection technology closer to life and entertainment. [0003] Traditional projectors are not easy to carry. Due to the mischievousness of students in school classrooms, it is not safe to place projectors in classrooms, and they are easy to be damaged by students. The portability of miniature projectors makes up for the vacancy in teaching. In the future, teachers only need to store materials in the projector It can be shown to students for teaching in...
