It can display various media formats such as videos, audios, pictures and documents, enrich the teaching content, promote students' participation and interaction, improve the learning interest and teaching effect, assist teachers in classroom demonstrations, and make the teaching content more vivid and intuitive.

[0003] During the use of the panel of the multimedia teaching terminal, it is usually docked with the corresponding mounting rack by fastening bolts to realize the installation and fixation of the panel of the multimedia teaching terminal. Then, external devices transmit data to the control device through the data interface. When the control device receives the data, through the regulation of the control device, the display device starts to operate, and finally the information is presented through the display device.

[0004] When the existing panel of the multimedia teaching terminal is in use, although it can be installed and fixed by bolt connection, the fastening bolts will slip and fall off after long-term use. The slipped and fallen screws will cause the panel of the multimedia teaching terminal to separate from the mounting rack, and finally cause property losses or personal injuries. For this reason, we propose a panel structure of a multimedia teaching terminal. Content of the Utility Model
