Display device used for electronic technique teaching

Abstract

The invention relates to the technical field of electronic teaching devices, and discloses a display device used for electronic technique teaching. The display device comprises a base, a supporting column, two demonstration boards and a fixing base. Wheels are arranged at the four corners on the lower portion of the base, the fixing base is arranged in the center over the base, the supporting column is installed in the center of the fixing base, and a frame body on the front side of the supporting column is sequentially provided with a loudspeaker, data interfaces, a rail and a loudspeaker; the two demonstration boards are an LED display screen and an electronic writing screen respectively, and the demonstration boards move in the rail in the supporting column through a three-way universaljoint clamped into the frame body of the supporting column. Tool boxes are symmetrically distributed at the corners on the lower portions of the LED display screen and the electronic writing screen,an armature is arranged in the middle of the left side of the LED display screen, and an electromagnet is installed in the middle of the right side of the electronic writing screen. The display devicehas the advantages of being compact in structure and convenient to use, the two folding demonstration screens, namely the LED display screen and the electronic writing screen, are adopted, the demonstration content is lively and rich, no dust remains, and the display device can be folded and occupies little space.

Description

Technical field [0001] The invention relates to the technical field of electronic teaching equipment, in particular to a display device for electronic technology teaching. Background technique [0002] The teaching board is a necessary tool used in the teaching process to let students have a deeper understanding of what they have learned, and can increase students' perceptual knowledge. [0003] With the continuous development of society and the improvement of education level, people begin to pay more and more attention to the quality of teaching, and the quality of teaching equipment often determines the quality of teaching. At present, the commonly used teaching boards are mostly magnetic, but most of the existing teaching boards are not foldable and disassembled. They occupy more space when not in use, and there is no place for teaching related supplies during the teaching process. In addition, the magnetic In response to the new teaching methods of today, the display board is ...

Problems solved by technology

At present, most commonly used teaching boards are magnetic suction type, but most of the existing teaching boards cannot be folded and disassembled, occupying a lot of space when not in use, and there is no place for teaching related supplies to be placed during the teaching process. In addition, the magnetic suction type In response to today's new teaching methods, the display board is boring and can not attract students' interest. At the same time, the dust generated by chalk writing will cause some troubles to the health of the teachers. The process of cleaning the teaching board is time-consuming and laborious.
