The connecting plate 9 is connected and fixed to the reinforcing plate and the positioning bolts, improving the connection and fixing effect between the LED display screen 2 and the connecting plate 9. A driver 10 and an infrared sensor 14 are respectively provided at the bottom inside the mounting base 7. A gear 11 is provided at the output end of the driver 10. An internal gear ring 12 that meshes with the gear 11 is installed inside the annular plate 5. An induction plate 13 that is opposite to the vertical plane of the infrared sensor 14 is installed inside the annular plate 5. A sealing groove 17 is provided inside the mounting base 7. The induction plate 13 rotates and moves inside the base 1 through the connection of the annular plate 5. The induction plate 13 and the infrared sensor 14 are intelligently sensed and positioned to form a reset structure, facilitating the formation of a reset structure by the pairing of the induction plate 13 and the infrared sensor 14, and facilitating the quick reset of the display screen. A writing board 16 is installed at one end of the sealing groove 17. A sealing door 18 that is hermetically matched with the sealing groove 17 is provided outside the mounting base 7. A semi-circular groove is provided at the bottom inside the sealing groove 17. The sealing door 18 is composed of two sets of bin doors, and the two sets of bin doors expand outwards, facilitating the placement of utensils in the semi-circular groove and increasing the convenience after the sealing groove is opened;

The indicator lights 8 are started under the control of the controller 15 so that during the interaction when the LED display screen 2 is being shown, when the answer is correct, the green light is started by the indicator light 8 as a representation, and when the answer is wrong, the red light is indicated, thereby increasing the interactive effect of the device and further improving the enthusiasm for interaction between students and teachers.

[0027] Working principle: In the interactive device selected by the reset button;

[0028] When in use, the problem can be displayed by starting the LED display screen 2, and interact with students to select a designated student to answer. Then, the driver 10 is actively started to drive the gear 11 to start, causing the gear 11 to mesh with the internal gear ring 12 structure. Then, the internal gear ring 12 drives the annular plate 5, the arc-shaped mounting base 3, and the assembled LED display screen 2 to rotate and adjust, so as to change the display orientation and angle of the LED display screen 2, and move the LED display screen 2 to the front view angle of the designated student for question and answer. When the question is answered correctly or wrongly, the indicator light 8 is started to emit light under the control of the controller 15, so as to indicate the right or wrong of the question according to the color. Press the reset button again, and the driver 10 is started by the start of the reset button to drive the annular plate 5 to drive the induction plate 13 to rotate and move. When the induction plate 13 is opposite to the vertical plane of the infrared sensor 14, the reset structure can be intelligently sensed to automatically stop the driver 10 and automatically reset the position of the LED display screen 2 for the next round of question and answer session. At the same time, during operation, the writing board 16 can be used for writing and display by opening the closing door 18, so as to provide a quick text expression method for teachers. The device combines the LED display screen and the teaching board, greatly improving the interactive effect between teachers and students and increasing the enthusiasm of students.
