Abstract

The invention provides a multifunctional teaching device for computer science and technology, which comprises a teaching box, a placement cavity, an observation sheet, an inlet / outlet, a box door, a rotatable adsorption support seat structure, a classified storage shielding box structure, a rotatable adsorption protection control box structure, a rotatable adjustment projection tube structure, a first support rod, a bolt nut, a rotating seat, a placement plate, a conical seat, a fixed connecting seat, a metal hose, a connecting block, a camera and an illuminating lamp, and the placing cavity is arranged in the teaching box. Through arrangement of the projection box, the second rotating rod, the fixing pipe, the inserting plate, the puller bolt, the first supporting rod, the bolt and the nut, loosening of the nut in the bolt and the nut in the using process is facilitated, then the fixing pipe and the inserting plate are rotated, meanwhile, the projection box is driven to rotate, and the nut in the bolt and the nut is tightened; the angle of the projector can be conveniently adjusted in work, and an adjusting function is added.

Description

technical field [0001] The invention belongs to the technical field of teaching devices, in particular to a multifunctional teaching device for computer science and technology. Background technique [0002] Existing computer science and technology majors often need to display samples for students to watch during teaching. Due to the small size of some samples, such as CPU, teachers need to step down from the podium to show the samples to students one by one and explain them, which is time-consuming and laborious. Reduce teaching efficiency, so people have designed computer science and technology teaching device in order to solve the above-mentioned problem. [0003] However, the existing teaching devices still have the inconvenience of adjusting the projection angle during use, moving and storing accessories during use, and inconveniently carrying out work during use. The problem of protection. [0004] Therefore, it is very necessary to invent a kind of multifunctional co...
