The invention discloses a height-adjustable teaching display device for education, which comprises a base. The upper end of the base is fixedly connected with a frame body. The inner walls of both ends of the frame body are provided with lifting mechanisms, and one end of the frame body rotates through and is provided with a transmission function. The extension mechanism, the two lifting mechanisms are connected with the extension mechanism, the drive mechanism is provided on the side wall of the frame body, and the drive mechanism is connected with the extension mechanism. There is a teaching board in the frame body, and the left and right side walls of the teaching board are respectively It is fixedly connected with the driving ends of the two lifting mechanisms. The front side wall of the teaching board is provided with an air collection box, the bottom of the air collection box is provided with an air collection port, and the top surface of the air collection box is connected with a bellows. A first air guide tube is fixedly penetrated through the surface, and the lower end of the first air guide tube communicates with the air outlet end of the bellows. The invention can not only adjust the height of the teaching board according to the teaching requirements, but also can absorb and process the dust generated when the teaching board is in use, so as to improve the environmental protection of the teaching device.
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...
