[0030] Example 2

[0031] Combined with appendix Figure 8 A large screen adjustment device for video conferencing includes a base 1, a support frame 2 fixedly mounted on the base 1, and a main display screen 3 mounted on the top of the support frame 2. Self-locking casters 17 are fixedly mounted at the four corners of the bottom of the base 1. Secondary display screens 5 are hinged to the left and right sides of the main display screen 3 via damping pivots 4. The support frame 2 has a lifting adjustment mechanism inside for adjusting the height of the main display screen 3. Two symmetrical arc-shaped slide rails 10 are fixedly mounted above the base 1, and arc-shaped sliders 11 slide on the two arc-shaped slide rails 10. A supporting frustum 6 is fixedly connected between the arc-shaped sliders 11. The base 1 has a rotation positioning mechanism for adjusting the horizontal rotation angle of the supporting frustum 6. The support frame 2 includes a sliding sleeve 7 fixedly mounted on the upper end of the supporting frustum 6 and a guide post 8 slidably mounted inside the sliding sleeve 7. The lifting adjustment mechanism uses an electric push rod 9, which is fixedly mounted between the bottom surface of the guide post 8 and the upper end of the supporting frustum 6.

[0032] The secondary display screen 5 is connected to the side of the main display screen 3 via a damping hinge 4. The rotation angle range along the damping hinge 4 is 0-180°. Both the main display screen 3 and the secondary display screen 5 are equipped with cameras 18, and the bottom of the secondary display screen 5 is equipped with a USB port 19.

[0033] In this embodiment, as a preferred technical solution, the rotary positioning mechanism includes a limiting bolt 16 threadedly connected to the outer side of the arc-shaped slider 11. The limiting bolt 16 passes through the arc-shaped slider 11 and abuts against the arc-shaped slide rail 10 to position the arc-shaped slider 11.

[0034] The working principle of this utility model is as follows: This large-screen adjustment device for video conferencing utilizes a lifting adjustment mechanism and a rotation positioning mechanism to adjust the height of the main display screen 3 and the horizontal rotation angle of the supporting frustum 6, respectively. Simultaneously, the damping pivot 4 allows the secondary display screen 5 to rotate within a certain angle range to meet different usage needs. Cameras 18 on both the main display screen 3 and the secondary display screen 5 are used for video conferencing image acquisition, and a USB port 19 at the bottom of the secondary display screen 5 facilitates the connection of external devices.

[0035] According to the solution described in Embodiment 1, the working process of this utility model is as follows:

[0036] 1. Moving device: The device is moved to a suitable position by pushing the self-locking casters 17 at the four corners of the bottom of the base 1, and then locking the self-locking casters 17 to fix the device.

[0037] 2. Adjust the height of the main display screen: Start the electric push rod 9. The electric push rod 9 drives the guide post 8 to slide up and down in the sliding sleeve 7, thereby adjusting the height of the main display screen 3.

[0038] 3. Adjust the angle of the secondary display screen: Manually operate the secondary display screen 5 to rotate it around the damping pivot 4. The rotation angle range is 0-180°. Adjust the angle of the secondary display screen 5 according to actual needs to expand the display of meeting content.

[0039] 4. Adjusting the horizontal rotation angle: Activate the drive motor 14 fixed inside the base 1. The drive motor 14 drives the drive gear 15 to rotate via a reducer, which in turn drives the driven gear 13 and the rotating shaft 12 to rotate, thereby causing the supporting platform 6 to rotate and adjusting the horizontal rotation angle of the main display screen 3 and the secondary display screen 5. When the supporting platform 6 rotates, the arc-shaped slider 11 slides on the arc-shaped slide rail 10, providing auxiliary support and guidance, while also limiting the rotation angle range. The geometric centers of the two arc-shaped slide rails coincide and are also aligned with the axis of the rotating shaft 12.

[0040] 5. Conduct video conferencing: Video images can be captured through the cameras 18 on the main display screen 3 and the secondary display screen 5. At the same time, relevant devices can be connected to the USB port 19 at the bottom of the secondary display screen 5.

[0041] Compared to Embodiment 1, Embodiment 2 changes the rotary positioning mechanism to a manual one. When the horizontal angle needs to be adjusted, the supporting frustum 6 is manually rotated, causing the arc-shaped slider 11 to slide on the arc-shaped slide rail 10, thereby changing the horizontal angle of the main display screen 3 and the secondary display screen 5. After adjusting to a suitable angle, the threaded limiting bolt 16 on the outer side of the arc-shaped slider 11 is tightened, so that the limiting bolt 16 passes through the arc-shaped slider 11 and abuts against the arc-shaped slide rail 10, thereby positioning the arc-shaped slider 11 and fixing the position of the supporting frustum 6.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
