[0028] 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.

[0029] Reference Figure 1-Figure 4 A conference terminal with an adjustable display screen angle includes a shell 1, a control mainboard 20 is installed inside the shell 1, a wireless transceiver 24 is also installed on one side of the shell 1, the wireless transceiver 24 is connected to the control mainboard 20 through a wire, the control mainboard 20 is a PCB circuit board or a single-chip circuit board, the wireless signal of the external device can be received through the wireless transceiver 24, and the signal is transmitted to the control mainboard 20, so that the staff can control the control mainboard 20 to work.

[0030] like Figure 1 , Figure 2 and Figure 6As shown, the top of the shell 1 is rotatably connected with a rotating shaft 17, the top of the rotating shaft 17 is fixedly installed with a support base 2, the top of the support base 2 is installed with a bracket 5, the bracket 5 is set in an "L" shape, and a display screen 4 is provided below the top of the bracket 5, a U-shaped block 26 is installed on the top of the display screen 4, the top of the bracket 5 is located in the U-shaped block 26, and the U-shaped block 26 is rotatably connected to the bracket 5 through a connecting shaft, and the display screen 4 is connected to the control main board 20 through a wire. The staff transmits the data of the external device to the control main board 20 through the wireless transceiver 24, and then transmits it to the display screen 4 by the control main board 20, and displays it through the display screen 4, so that a remote conference can be completed.

[0031] It should be noted that the bottom of the support base 2 is clearance-matched with the top of the shell 1 , and the support base 2 can support the bracket 5 so that the bracket 5 and the display screen 4 remain stable.

[0032] like Figure 2 and Figure 4 As shown, the bottom of the rotating shaft 17 extends into the interior of the housing 1, and a turbine 15 is installed at the bottom of the rotating shaft 17. Two mounting plates 14 are also symmetrically installed inside the housing 1. A worm 16 is rotatably connected between the two mounting plates 14. The worm 16 is meshed with the turbine 15, and one end of the worm 16 is connected to a drive motor 13. The drive motor 13 is fixed on the mounting plate 14. The drive motor 13 is connected to the control main board 20 through a wire. In actual use, the control main board 20 can control the drive motor 13 to work. With the cooperation of the turbine 15 and the worm 16, the display screen 4 can be driven to rotate horizontally to adjust the horizontal angle of the display screen 4.

[0033] Furthermore, there is a self-locking property between the turbine 15 and the worm 16. After the driving motor 13 has completed the angle adjustment, the display screen 4 will not be hit by foreign objects and change its angle.

[0034] It should be noted that if Figure 2 As shown, the control main board 20 is separated from the turbine 15 and the worm 16 by the mounting plate 14 , so that the turbine 15 and the worm 16 will not affect the control main board 20 .

[0035] like Figure 3 As shown, a strip support plate 3 is installed on one side of the bracket 5, and both ends of the top of the strip support plate 3 are rotatably connected to electric push rods 18. The other end of the electric push rod 18 is rotatably connected to the side of the display screen 4, and the electric push rod 18 is connected to the control main board 20 through a wire. During actual use, the control main board 20 can control the extension and retraction of the electric push rod 18, thereby adjusting the vertical angle of the display screen 4.

[0036] It should be noted that the rotation angle of the rotating shaft 17 is A, 0°≤A≤360°, so that when the rotating shaft 17 rotates, the wires on the display screen 4 and the electric push rod 18 will not be entangled on the bracket 5, and the wiring of the display screen 4 and the electric push rod 18 will not be affected.

[0037] like Figure 1 As shown, a protective cover 8 is installed on one side of the top of the support base 2, the opening of the protective cover 8 is upward, and the protective cover 8 is located below the display screen 4, and a strip baffle 7 is installed on the top of the bracket 5. When the top of the protective cover 8 and the bottom of the strip baffle 7 are in contact, the display screen 4 is located in the protective cover 8. When the display screen 4 is not in use, the protective cover 8 can be moved to the upper side and the display screen 4 can be stored in the protective cover 8 to protect the display screen 4.

[0038] It should be noted that if Figure 3 As shown, an opening groove 11 is symmetrically opened on one side of the protective cover 8 close to the bracket 5. When the top of the protective cover 8 contacts the bottom of the strip baffle 7, the electric push rod 18 is located in the opening groove 11. In this way, during the process of lifting the protective cover 8, the electric push rod 18 will not hinder the protective cover 8.

[0039] like Figure 2 As shown, a connecting block 21 is installed on one side of the protective cover 8. The connecting block 21 is set in an "L" shape, and one end of the connecting block 21 is slidably matched with a guide rail fixed on the bracket 5 through a slider. With the cooperation of the connecting block 21 and the guide rail, the protective cover 8 can be limited to prevent the position of the protective cover 8 from being offset.

[0040] like Figure 5 As shown, a first locking block 10 is installed on one side of the top of the protective cover 8, the top of the first locking block 10 extends to the top of the strip baffle 7, and a through slot 9 is opened on the side of the first locking block 10, and a limiting sleeve 6 is installed on the top of the strip baffle 7, and a second locking block 19 is slidably connected in the limiting sleeve 6, and one end of the second locking block 19 passes through the through slot 9. In actual use, when the protective cover 8 is put on the display screen 4, the through slot 9 on the first locking block 10 is aligned with the second locking block 19, and the staff pushes the second locking block 19 and inserts one end of the second locking block 19 into the through slot 9, so that the protective cover 8 can be fixed, and the fixation is convenient.

[0041] Specifically, when the angle of the display screen 4 needs to be adjusted, the staff controls the drive motor 13 and the electric push rod 18 to work through the control mainboard 20. The drive motor 13 drives the rotating shaft 17 to rotate through the turbine 15 and the worm 16, thereby making the bracket 5 and the display screen 4 rotate horizontally. At the same time, the electric push rod 18 extends to push the display screen 4 to rotate vertically. When the display screen 4 is adjusted to a preset angle, the staff controls the drive motor 13 and the electric push rod 18 to stop working through the control mainboard 20 to complete the angle adjustment of the display screen 4. After use, the staff restores the display screen 4 to its initial position through the drive motor 13 and the electric push rod 18, and then pulls the protective cover 8 upwards, and the protective cover 8 moves upwards along the guide rail. When the protective cover 8 moves to the top, the second locking block 19 is used to insert one end of the second locking block 19 into the through groove 9 to fix the protective cover 8. The display screen 4 is located in the protective cover 8, which can protect the display screen 4.

[0042] Furthermore, Figure 5 As shown, a strip block 22 is installed at one end of the second locking block 19, and the top of the strip block 22 extends to the top of the limiting sleeve 6, and a limiting groove 23 is also provided on the top of the second locking block 19. When the side of the strip block 22 contacts the end of the limiting sleeve 6, the limiting groove 23 is aligned with the through groove 9, and the top of the through groove 9 is located in the limiting groove 23. In actual use, when the second locking block 19 is inserted into the through groove 9, under the action of gravity, the protective cover 8 will drive the first locking block 10 to move downward, so that the top of the through groove 9 will move into the limiting groove 23, jamming the second locking block 19 to prevent the second locking block 19 from loosening by itself.

[0043] Furthermore, Figure 3 As shown, a receiving groove 25 is provided at one end of the top of the protective cover 8 close to the bracket 5. When the top of the protective cover 8 contacts the bottom of the strip baffle 7, the top of the bracket 5 is located in the receiving groove 25, so that the bracket 5 will not hinder the movement of the protective cover 8.

[0044] Furthermore, Figure 1 As shown, a brake universal wheel 12 is installed on the bottom edge of the housing 1, and the housing 1 and the display screen 4 can be conveniently moved by the brake universal wheel 12.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
