Demonstration teaching aid for computer principle teaching

Abstract

The invention discloses a demonstration teaching aid for computer principle teaching, relates to the technical field of demonstration teaching aids for teaching, and solves the problem that the process of detaching a whole computer type touch screen by a worker is relatively slow. A demonstration teaching aid for computer principle teaching comprises a computer type touch screen, an L-shaped clamping plate B is arranged at the upper end of the computer type touch screen in a clamped mode, an L-shaped clamping plate A is arranged at the lower end of the computer type touch screen in a clamped mode, and a connecting rod is fixedly welded to the middle of the lower end of the L-shaped clamping plate A; and an angle adjusting mechanism is movably arranged at the lower end of the connecting rod, a supporting rod is fixedly welded to the lower end of the angle adjusting mechanism, and a plug-in mounting type fixing plate is fixedly connected to the rear end of the computer type touch screen in a fusion mode. The extension spring is arranged in the cylindrical shell, so that the interior of the cylindrical shell is elastically connected with the U-shaped clamping groove through the extension spring.

Description

technical field [0001] The invention relates to the technical field of demonstration teaching aids for teaching, in particular to a demonstration teaching aid for teaching computer principles. Background technique [0002] With the rapid development of social economy, teaching demonstration teaching aids enable students to intuitively and visually understand the teaching content. The general term for all kinds of utensils used by teachers and the utensils used by teachers in teaching. Teaching demonstration teaching aids have gradually evolved from the original blackboard and whiteboard. For the current multimedia teaching, multimedia teaching uses a large number of modern electronic teaching aids such as computer touch screens. [0003] However, most of the computer-type touch screens on the existing teaching demonstration teaching aids are clamped by bolts to the support structure, which makes the disassembly process of the whole computer-type touch screen relatively slow ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of demonstration teaching aid for computer principle teaching, to solve the problem that the computer-type touch screen on the teaching demonstration teaching aid proposed in the above-mentioned background technology is mostly clamped by bolt connection between the supporting structure, so that the staff will have a good understanding of the whole The disassembly process of the computer-type touch screen is relatively slow, and it is impossible to quickly disassemble and replace the damaged computer-type touch screen, and the existing computer-type touch screen cannot adjust the angle, so that students cannot see clearly when looking at the computer-type touch screen due to the reflection effect And other issues
