Embodiment 1

[0023] see Figure 1~3 , in Embodiment 1 of the present invention, an automatic control teaching demonstration device includes a base 1, a lifting assembly 2 installed on the base 1, a support member 6 rotatably arranged on the lifting assembly 2, and a support member 6 arranged on the support member 6. The left extension assembly 3 and the right extension assembly 4, the left extension assembly 3 includes a frame one 31 and a connecting rod one 33, the right extension assembly 4 includes a frame two 41 and a connecting rod two 43, and the frame one 31 and frame 2 41 are respectively slid through through hole 1 62 and through hole 2 63 on the support member 6, and the frame 1 31 and frame 2 41 are respectively provided with reel 1 34 and Reel 2 44, and reel 1 34 and reel 2 44 are all curled with interconnected projection screens, and the first rotating assembly 7 is installed on the mounting groove 64 inside the support member 6, and the first rotating assembly 7 is set. It i...

Embodiment 2

[0026] see Figure 1~3 The main difference between this embodiment 2 and embodiment 1 is that a pole 65 is fixedly installed on the support member 6, and a projector 61 is installed on the end of the pole 65 away from the support member 6, and the projector 61 is set for Projection on the projection screen.

[0027] A motor three is also arranged inside the installation slot 64 , and the motor three is in transmission connection with the pulley 75 on the rotating shaft 71 . The third motor provides power for the rotation of the rotating shaft 71 .

[0028] The bottom of the support member 6 is rotatably installed on the lifting assembly 2, which is convenient for adjusting the angle of the support member 6, thereby adjusting the angle of the projection screen.

[0029] The lifting assembly 2 is provided with a second rotating assembly that drives the support member 6 to rotate automatically. The second rotating assembly provides power for the rotation of the support member ...

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an automatic control teaching demonstration device. Background technique [0002] In the teaching process, the teacher needs to impart some knowledge to the students. Since there are more students in each class, in order to make it convenient for all students to observe, traditionally, the teacher will draw graphics or knowledge points on the blackboard. With continuous development, people are gradually using multimedia teaching in the field of teaching. [0003] However, the size and area of ​​the screen cloth of the multimedia teaching projection in the prior art cannot be adjusted, so only certain information can be fixedly projected each time, and the projected area cannot be adjusted according to the size of the classroom, and cannot meet the needs of different teachers. Requirements, so it is necessary to design an automatic control teaching demonstration device...
