[0022] The embodiment of the present application provides a video conferencing display device, which effectively solves the existing display device, in which the display is raised and lowered by a motor inside, and is large and bulky. When it is necessary to move the display to a larger space for a meeting, it is difficult to carry the display, which is a time-consuming and labor-intensive technical problem. The pull plate is pulled, and the first rack at the bottom of the pull plate is meshed with the second gear, which drives the second gear to rotate, and then the meshing of the second gear and the transmission belt drives the transmission belt to rotate. The transmission belt drives the first gear to rotate by rotating with the first gear, and the first gear drives the two second racks to slide inward at the same time by meshing with the two second racks. When the two second racks slide inward, the scissor-type lifting frame will rise upward to pull the curtain to unfold, and at the same time, the spring at the side end of the curtain will accumulate power. While pulling the pull plate, the pull rod will drag the support rod to rotate the support rod to lift the projection frame upward to adjust the angle of the projector. , so that the projector can be projected on the screen, and the screen and the projector can be unfolded by pulling the pull plate, so that the effect of being able to be quickly unfolded for use is achieved, and the pull plate is pushed into the storage box, and the first rack at the bottom of the pull plate is meshed with the second gear, which will drive the second gear to rotate, and then the meshing of the second gear and the transmission belt will drive the transmission belt to rotate, and the transmission belt drives the first gear to rotate through the rotation of the first gear, and the first gear will drive the two second racks to slide outward at the same time through the meshing with the two second racks, and the second rack sliding outward will cause the scissor-type lifting frame to descend, and the spring at the side end of the screen will roll up the screen into the storage box. While pushing the pull plate, the pull rod will push the support rod, so that the support rod rotates and pulls the projection frame downward, so that the projection frame is reset to complete the storage, and the screen and the projector can be quickly stored by pushing the pull plate. The volume is small after storage, which achieves the effect of easy mobile storage.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing display device uses a motor to lift the display, is large and bulky, and is difficult to carry when it needs to be moved to a larger space for meetings, etc., which is time-consuming and laborious. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a video conferencing display device, including a storage box 1, a pull plate 3 is slidably installed on the side end of the storage box 1, a projection stand 4 is rotatably installed on the top of the pull plate 3, and a screen 6 is rotatably installed inside the storage box 1; a spring is installed on the side end of the screen 6 for storing power.

[0026] A top cover 2 is installed at the top of the storage box 1, a scissor-type lifting frame 8 is slidably installed at the bottom end of the top cover 2, two second racks 9 are fixedly installed at the bottom end of the scissor-type lifting frame 8, a first gear 11 is rotatably installed inside the storage box 1, a second gear 14 is rotatably installed inside the storage box 1, and a transmission belt 15 is rotatably installed inside the storage box 1; the first gear 11 is meshed with the two second racks 9.

[0027] The transmission belt 15 is meshed with the first gear 11 and the second gear 14. A pull rod 12 is fixedly installed inside the storage box 1. A support rod 13 is rotatably installed on the side end of the pull rod 12. A projector 7 is fixedly installed inside the projection stand 4. The projector 7 is rotatably connected to the support rod 13. A first rack 5 is fixedly installed on the bottom end of the pull plate 3. The first rack 5 is meshed with the second gear 14.

[0028] Working principle:

[0029] The first step is to pull the pull plate 3 when in use, and the first rack 5 at the bottom of the pull plate 3 is meshed with the second gear 14, which will drive the second gear 14 to rotate, and then the meshing of the second gear 14 and the transmission belt 15 will drive the transmission belt 15 to rotate, and the transmission belt 15 drives the first gear 11 to rotate by rotating with the first gear 11, and the first gear 11 will drive the two second racks 9 to slide inward at the same time by meshing with the two second racks 9. When the two second racks 9 slide inward, the scissor-type lifting frame 8 will rise upward to pull the curtain 6 to unfold, and at the same time, the spring at the side end of the curtain 6 will accumulate power. While pulling the pull plate 3, the pull rod 12 will drag the support rod 13, so that the support rod 13 rotates and lifts the projection frame 4 upward, adjusts the angle of the projector 7, and enables the projector 7 to be projected on the curtain 6, and the curtain 6 and the projector 7 are unfolded by pulling the pull plate 3, so that the effect of being able to be quickly unfolded for use is achieved.

[0030] The second step, when the use is completed, the pull plate 3 is pushed into the storage box 1, and the first rack 5 at the bottom of the pull plate 3 is meshed with the second gear 14, which will drive the second gear 14 to rotate, and then the meshing of the second gear 14 and the transmission belt 15 will drive the transmission belt 15 to rotate, and the transmission belt 15 drives the first gear 11 to rotate by rotating with the first gear 11, and the first gear 11 will drive the two second racks 9 to slide outward at the same time by meshing with the two second racks 9, and the second racks 9 sliding outward will cause the scissor lift 8 to drop, and the spring at the side end of the curtain 6 will roll up the curtain 6 into the storage box 1, while pushing the pull plate 3, the pull rod 12 will push the support rod 13, so that the support rod 13 rotates downward to pull the projection frame 4, so that the projection frame 4 is reset to complete the storage, and the curtain 6 and the projector 7 are quickly stored by pushing the pull plate 3. The volume is small after storage, which achieves the effect of easy mobile storage.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
