Safe electronic commerce teaching system

Abstract

The invention discloses a safe electronic commerce teaching system in the field of commerce teaching system display, and the system comprises a curtain system and a projection system; the projection system comprises a lifting assembly, a transverse moving assembly and a projector; the curtain system comprises a driving assembly, a curtain rolling shaft, a curtain moving shaft and a curtain; the lifting assembly controls the lifting of the projector; the transverse moving assembly controls the projector to move; the curtain rolling shaft controls the curtain to be unwound or wound; and the curtain moving shaft controls the curtain to move. Through the structure, the problems that the curtain and the projector cannot be installed at the optimal position when a traditional curtain and projector are installed, so that the use effect of the curtain and the projector cannot be optimal after installation, the screen after screen projection is very fuzzy, light reflection is caused when students at some positions watch the curtain, and the teaching effect is affected are solved.

Description

technical field [0001] The invention relates to the display field of business teaching systems, in particular to a safe e-commerce teaching system. Background technique [0002] With the rapid development of the Internet and modern multimedia technology, many schools now widely use multimedia display forms for teaching. The content of the project is projected onto the screen, but the position of the traditional projector and the screen cannot be adjusted after installation. Since the use process cannot be simulated during installation, the screen and projector cannot be installed in the best position, so the screen and the projector cannot be adjusted. After the projector is installed, the use effect cannot be optimal, which may make the screen very blurred after projection, and students in some positions will cause reflections when looking at the screen, which will affect the teaching effect. [0003] Therefore, the present invention provides a secure e-commerce teaching s...
