Double-sided blackboard for electronic engineering teaching

Abstract

The invention relates to a double-sided blackboard for electronic engineering teaching. The double-sided blackboard for electronic engineering teaching comprises a main body and discs, an upper protection plate is arranged at the top end of the main body, the main body and the upper protection plate are fixedly connected, movable grooves are fixed to the inner side of the upper protection plate, and the upper protection plate and the movable grooves are fixedly connected. Connecting rods are connected to the inner side of the movable grooves, the movable grooves are connected with the connecting rods in a welded mode, sandwich plates are arranged at the bottom ends of the movable grooves, and installation plates are fixed to the middle parts of the sandwich plates. The double-sided blackboard has the beneficial effects that the movement of clamping pins between the installation plates and the sandwich plates enable the sandwich plates to be clamped to the surface of the main body, andteaching adjusting can be performed according to electronic engineering teaching courses; when the blackboard is required to be written, the installation plates and the clamping pins can be opened forteaching; and when multimedia teaching is required, the clamping pins can be clamped to the sandwich plates for teaching, the problem of poor reflection effect of the blackboard can be avoided, and the quality of multimedia teaching is improved.

Description

technical field [0001] The invention relates to the technical field of electronic engineering teaching, in particular to a double-sided blackboard for electronic engineering teaching. Background technique [0002] Electronic engineering, also known as "weak current technology" or "information technology", can be further subdivided into electrical measurement technology, adjustment technology and electronic technology. Electronic engineering is a subcategory of electrical engineering and is an engineering for the electronic field. Its research object has gone beyond the electronic field. Electronic teaching mainly cultivates advanced engineering and technical personnel who can engage in the research, design, manufacture, application and development of various electronic equipment and information systems. However, the teaching blackboard is relatively backward, which is easy to affect the teaching effect of students. , so it is necessary to improve the electronic engineering t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a double-sided blackboard for electronic engineering teaching, to solve the electronic engineering teaching on the market proposed in the above background technology, the blackboard reflects light during multimedia teaching, and affects the progress of electronic engineering teaching, and the blackboard mainly It is a single-sided structure, and the writing content on the surface is relatively small, which affects the teaching progress of the teaching teacher, and it is easy to generate a lot of chalk dust, and it is easy to diffuse around the classroom, and the size of the blackboard adjustment surface is relatively narrow.
