Novel multimedia teaching device for education

Abstract

The novel multimedia teaching device comprises a protection box and a multimedia teaching display screen located on the inner side of the protection box, a protection box cover is fixed to the top of the multimedia teaching display screen, limiting cylinders are fixed to the left side and the right side of the top of the protection box respectively, and limiting rods are slidably connected to the inner walls of the limiting cylinders in a sleeving mode; the upper ends of the two limiting rods are fixedly connected with the left end and the right end of the protection box cover respectively, and lifting rods are fixed to the left portion and the right portion of the back of the multimedia teaching display screen respectively. Compared with the prior art, the multimedia teaching display screen has the advantages that through cooperation of the protective box, the protective box cover, the lifting rod, the gear, the worm gear, the worm and other structural components, the multimedia teaching display screen can be conveniently lifted during use, then the multimedia teaching display screen can be used for teaching, and when the multimedia teaching display screen is not used, the multimedia teaching display screen can be conveniently descended and stored in the protective box; therefore, an effective anti-collision protection function can be provided for the multimedia teaching display screen, and the overall space occupation of the multimedia teaching device is smaller.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching equipment, in particular to a novel multimedia teaching device for pedagogy. Background technique [0002] Multimedia teaching all-in-one machine integrates multiple technologies such as infrared touch technology, intelligent office teaching software, multimedia network communication technology and high-definition flat panel display technology, and integrates projector, electronic whiteboard, computer (optional), TV and touch screen It is a multi-functional interactive teaching device that integrates multiple devices such as functions, and upgrades the traditional display terminal to a full-featured human-computer interaction device.

Problems solved by technology

[0003] However, the multimedia teaching all-in-one machine in the prior art is generally a structure in which the multimedia teaching display screen is installed and fixed on a movable support frame. There is no protective structure for the teaching display screen on the all-in-one machine, which causes the all-in-one machine to display The screen is easy to be bumped, and the display screen is easily damaged once it is bumped, and the all-in-one machine does not have the function of telescopic adjustment, so the all-in-one machine still takes up a relatively large indoor space when it is not in use
