[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A screen projection device for video conferencing includes a support rod 1, a fixing frame 7 is fixedly connected to the front of the support rod 1, and a threaded rod 8 is inserted inside the fixing frame 7, a second threaded sleeve 20 is sleeved on the surface of the threaded rod 8, and a second support plate 19 is fixedly connected to the front of the second threaded sleeve 20, a shaft rod 13 is fixedly installed on the surface of the second support plate 19, and a transmission gear 12 is sleeved on the surface of the shaft rod 13, a connecting rod 14 is fixedly connected to the front of the transmission gear 12, and a first support plate 2 is fixedly connected to the front of the connecting rod 14, a support frame 3 is symmetrically fixedly installed on the front of the first support plate 2, a screen 5 is inserted between the support frames 3, and a drawing board 6 is fixedly connected to the surface of the support frame 3.

[0024] Further, see Figure 3 and Figure 4 It can be known that sliders 4 are symmetrically fixedly connected at the upper and lower ends of the screen 5, and a sliding groove adapted to the slider 4 is opened on the surface of the support frame 3. The slider 4 is inserted inside the sliding groove. During use, the sliding groove is used to limit the slider 4, thereby facilitating the screen 5 to move left and right and enter the interior of the drawing board 6 for storage.

[0025] Further, see Figure 4 and Figure 5 It can be known that a hole groove is provided on the surface of the first support plate 2, and a limit pin 11 is inserted into the inside of the hole groove, and a return spring 17 and a fixed disk 18 are sequentially sleeved on the surface of the limit pin 11, one end of the return spring 17 is fixedly connected to the surface of the first support plate 2, and the other end of the return spring 17 is fixedly connected to the surface of the fixed disk 18. During use, the elastic force of the return spring 17 itself facilitates the limit pin 11 to limit the slider 4.

[0026] Further, see Figure 5 and Figure 6It can be known that the bottom end of the drawing board 6 is in contact with the bearing sleeve 15, and the bottom end of the bearing sleeve 15 is in contact with the first threaded sleeve 16. During use, the first threaded sleeve 16 can push the drawing board 6 to move up and down on the surface of the threaded rod 8, thereby facilitating the adjustment of the height of the first support plate 2.

[0027] Further, see Figure 5 and Figure 6 It can be known that the surface of the transmission gear 12 is in contact with the transmission gear rod 10, and the surface of the transmission gear rod 10 is sleeved with a fixed cover 9. During use, the transmission gear rod 10 can be rotated clockwise or counterclockwise to drive the transmission gear 12 to rotate, thereby facilitating the adjustment of the angle of the first support plate 2.

[0028] Further, see Figure 3 and Figure 4 It can be known that a limit groove compatible with the limit pin 11 is provided on the surface of the slider 4, and the limit pin 11 is snap-connected to the slider 4. During use, when the slider 4 slides to the right side of the slide groove, the limit pin 11 is inserted into the inside of the limit groove by the elastic force of the return spring 17 itself, thereby facilitating the limiting function.

[0029] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, when the angle of the first support plate 2 needs to be adjusted, the staff manually rotates the transmission gear rod 10, the transmission gear rod 10 drives the transmission gear 12 to rotate, the transmission gear 12 rotates and drives the connecting rod 14 to rotate, and the connecting rod 14 rotates and drives the first support plate 2 to rotate left and right to adjust the angle;

[0030] When the height of the first support plate 2 needs to be adjusted, the staff manually rotates the first threaded sleeve 16, and the first threaded sleeve 16 pushes the bearing sleeve 15 to move on the surface of the threaded rod 8, thereby facilitating the height adjustment of the second threaded sleeve 20, thereby facilitating the first support plate 2 to be driven to adjust its height;

[0031] When the screen 5 needs to be stored, the staff manually pushes the screen 5 to move to the right along the surface of the first support plate 2, and the screen 5 drives the slider 4 to move. When the slider 4 moves to the right side of the slide groove, the return spring 17 pushes the limit pin 11 through its own elastic force to be inserted into the limit groove opened by the slider 4, thereby fixing and limiting it. The operation is completed. The above is the entire working principle of the utility model.

[0032] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology.
