The device includes a base, an upper end of the base is fixedly connected with a frame body; lifting mechanisms are arranged on inner walls of two ends of the frame body; an extension mechanism with a transmission function rotationally penetrates one end of the frame body; the two lifting mechanisms are in transmission connection with the extension mechanism; a driving mechanism is arranged on a side wall of the frame body; the driving mechanism is matched and connected with the extending mechanism; a teaching board is arranged in the frame body, left and right end side walls of the teaching board are fixedly connected with driving ends of the two lifting mechanisms respectively; a gas collection box is arranged on a side wall of a front end of the teaching board, a gas collection opening is formed in the bottom of the gas collection box, a corrugated pipe is communicated with a top face of the gas collection box, a first gas guide pipe fixedly penetrates a top face of the frame body, and a lower end of the first gas guide pipe is communicated with a gas outlet end of the corrugated pipe. The heightof the teaching board can be adjusted according to the use requirements of teaching, in addition, dust generated in the use process of the teaching board can be absorbed, and the environmental protection property of the teaching device is improved.
Description
technical field [0001] The invention relates to the technical field of teaching display devices, in particular to a height-adjustable teaching display device for education. Background technique [0002] With the advancement of science and technology, multimedia teaching is booming in our country. Computers, projectors, etc. have gradually replaced traditional teaching tools such as blackboards and chalk, and have achieved good results in the application of teaching, training, and reporting. At present, in the teaching process, as teaching pays more and more attention to the connection between classroom teaching and actual social culture, the scope of expansion of teaching content becomes larger. [0003] However, during the teaching display process of time, the blackboard is still one of the commonly used display tools, and its height is not easy to adjust during use. In addition, during the teaching display, the dust generated cannot be absorbed and processed, making the t...
