[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] Embodiments of this utility model: such as Figure 1 , 2 As shown in Figures 3, 4, and 5, a screen rotating bracket includes a vertical support rod 1, a horizontal support rod 2, and a display screen. There are three horizontal support rods 2 and three display screens. The middle display screen is the main display screen 3, and the displays screens on either side are secondary display screens 4. The horizontal support rod 2 corresponding to the main display screen 3 is fixedly mounted on the vertical support rod 1, and the horizontal support rod 2 corresponding to the secondary display screens 4 is rotatably mounted on the vertical support rod 1. The main display screen 3 has a first hinge seat 5 on both sides, and the secondary display screens 4 have a second hinge seat 6. The first hinge seat 5 has an electrically operated telescopic column 7, which extends into the hinge hole on the second hinge seat 6 to connect the first hinge seat 5 and the second hinge seat 6. The horizontal support rod 2 is an electrically operated telescopic rod, and its end away from the vertical support rod 1 has a vertical rotation mechanism 8. The main display screen 3 is fixed to the corresponding vertical rotation mechanism 8, and the secondary display screens 4 are hinged to the corresponding vertical rotation mechanism 8.

[0017] It is worth noting that the electric telescopic column 7 adopts a miniature electric telescopic rod; the hinge between the vertical rotation mechanism 8 and the secondary display screen 4 adopts a damped hinge, so that the display screen does not rotate when no external force is applied, and the hinge axis here is set vertically.

[0018] With the above structure, when displaying a normal image, the three displays are separated by extending the support crossbar 2. Then, the angle of each display can be adjusted by the vertical rotation mechanism 8, making it easier for viewers below the display to see the screen. When a wider image needs to be displayed or when used as a subtitle display or teleprompter, the three displays are first made vertical. Then, the support crossbar 2 is retracted, allowing the hinge seat 5 on the three displays to align with the hinge seat 6. The electric telescopic column 7 is used to connect the hinge seat 5 and the hinge seat 6, allowing the three displays to be combined into a whole. At this time, the support crossbar 2 extends and rotates around the support vertical bar 1, allowing the secondary display 4 to rotate and be placed on the same plane as the main display 3.

[0019] like Figure 6 As shown, the support crossbar 2 is provided with an installation sleeve 9 at one end near the support vertical bar 1, and the support vertical bar 1 is provided with a limiting annular groove 10 corresponding to the installation sleeve 9, and the installation sleeve 9 is installed in the limiting annular groove 10.

[0020] like Figure 6 As shown, the mounting sleeve 9 includes two semi-rings 11, which are connected together by bolts.

[0021] Through the above mechanism, the mounting sleeve 9 and the supporting vertical rod 1 can be detachably connected, which facilitates installation, disassembly, maintenance or transportation.

[0022] like Figure 6 As shown, the support crossbar 2 connected to the main display screen 3 is support crossbar 12, and the support crossbar 2 connected to the secondary display screen 4 is support crossbar 23. The inner wall of the mounting sleeve 9 is provided with a toothed annular groove 14. The side wall of the limiting annular groove 10 corresponding to support crossbar 12 is provided with a toothed ring 15. The toothed ring 15 and the toothed annular groove 14 are engaged and locked together. Multiple transmission gears 16 are rotatably provided on the side wall of the limiting annular groove 10 corresponding to support crossbar 23. The transmission gears 16 mesh with the toothed annular groove 14.

[0023] As shown in Figure 7, the support vertical rod 1 is equipped with a drive motor 17. Two drive gears 18 are rotatably mounted on the output shaft of the drive motor 17. The two drive gears 18 correspond to the two support horizontal rods 13 respectively and mesh with the surrounding transmission gears 16. A snap ring 19 is provided on the side of the two drive gears 18 that are close to each other. A snap slider 20 is provided between the two drive gears 18. The snap slider 20 is slidably mounted on the drive motor 17 and can snap with one of the snap rings 19. The support vertical rod 1 is equipped with a drive component 21 that drives the snap slider 20 to move up and down.

[0024] It is worth noting that the snap-fit ​​slider 20 and the drive motor 17 are connected by an output shaft key.

[0025] like Figure 7 , 8 As shown, the driving component 21 consists of two electromagnets, and only one electromagnet can be energized at a time. The locking slider 20 has a limiting ring groove 22 in the middle, and a magnetic ring 23 made of magnetic material is fitted inside the limiting ring groove 22.

[0026] It is worth noting that the magnetic ring is rotatably connected to the snap-fit ​​slider 20, and the two electromagnets can be controlled by a single-pole double-throw switch. When electromagnet one is energized, electromagnet two is de-energized, thereby allowing the two secondary display screens 4 to rotate independently.

[0027] With the above structure, when the electromagnet is energized, it attracts the magnetic ring 23, which drives the locking slider 20 to move and engage with one of the locking rings 19. The output shaft of the drive motor 17 rotates, which drives the locking slider 20 to rotate, thereby driving the locking ring 19 and the drive gear 18 to rotate, which in turn drives the corresponding support crossbar 13 to rotate, adjusting the orientation of the secondary display screen 4.

[0028] It is worth noting that the orientation adjustment range of the secondary display screen 4 is 0-90°.

[0029] The vertical rotation mechanism 8 includes an angle adjustment seat 24 and a second drive motor 25. The second drive motor 25 is fixed on the support crossbar 2. The angle adjustment block 24 is hinged to the support crossbar 2 and is driven to rotate by the second drive motor 25.

[0030] It is worth noting that the vertical angle adjustment range of the display screen is 0-90°.

[0031] With the above structure, the drive motor 25 drives the angle adjustment block 2 to rotate vertically, thereby adjusting the angle of the display screen so that the audience below can easily view the display screen.

[0032] In practical implementation: 1. When used as a regular screen, the secondary display screen 4 can be rotated horizontally by drive motor 17 to adjust its orientation, or the main display screen 3 and secondary display screen 4 can be rotated vertically by drive motor 25 to adjust their angles. 2. When used as a subtitle display screen or teleprompter, firstly, the hinge base 5 on the three displays screens is connected to the hinge base 6. Then, the electric telescopic column 7 is used to connect the hinge base 5 and the hinge base 6, making the three displays screens a single unit. At this time, the support crossbar 2 extends and rotates around the support vertical bar 1, which allows the secondary display screen 4 to rotate, placing it on the same plane as the main display screen 3, thus enabling the display of longer subtitles, wider images, etc.
