This bracket base is used to install an external device, and the external device can rotate relative to the base body 30 through the rotating base, thereby driving the external device to rotate to achieve the angle adjustment function of the external device. It should be noted that the external device in this embodiment can be a display screen or other products with angle adjustment requirements. In this application, the external device is taken as a display screen as an example to illustrate this base structure.

[0058] Among them, the rotating base includes a first rotating seat 21 disposed in the accommodating space and a first friction plate 22 located between the first rotating seat 21 and the bottom plate 32; the first friction plate 22 is connected to the base and the first rotating seat 21, and when the first rotating seat 21 rotates, it drives the first friction plate 22 to rotate; the bracket assembly 10 is disposed on the first rotating seat 21. In this embodiment, by providing a rotating assembly 20 including the first rotating seat 21 and disposing the bracket assembly 10 on the first rotating seat 21, when rotating the display screen on the bracket assembly 10, the rotating assembly 20 is driven to rotate by the bracket assembly 10, and the angle adjustment function of the display screen can be realized; and by providing the first friction plate 22 to provide torque for the rotation of the first rotating seat 21, it is convenient to control the rotation angle of the display screen.

Specifically, the fastener 40 is a locking screw, and the corresponding connection hole 211 is a threaded hole, and the locking screw is threadedly connected to the threaded hole. By tightening or loosening the locking screw, the friction between the first friction plate 22 and the bottom plate 32 is adjusted, so as to adjust the torque during rotation, so as to facilitate controlling the rotation force of the base structure.

In this embodiment, by providing the first friction plate 22 and the second friction plate 24; when the angle of the display screen needs to be adjusted, the bracket assembly 10 rotates relative to the base body 30 through the rotating assembly 20. At the same time, the first friction plate 22 and the second friction plate 24 provide rotational torque for the bracket assembly 10, facilitating the control of the force when the base rotates and being conducive to the adjustment of small angles during the rotation process.

[0063] In this embodiment, when the rotating assembly 20 and the base body 30 are assembled, first, the first rotating seat 21 and the first friction plate 22 are assembled onto the base body 30; then, the second friction plate 24 and the second rotating seat 23 are sequentially assembled under the base body 30, and then the rotating assembly 20 and the base body 30 are connected together through the fastener 40.

[0064] Please refer to Figure 5 and Figure 6 , in some embodiments, the bottom plate 32 is provided with a first shaft hole 321; the cover plate 31 is provided with a second shaft hole 311, and the first rotating seat 21 is arranged in the second shaft hole 311; a ring-shaped first protrusion 212 is formed on one side of the first rotating seat 21 close to the bottom plate 32; the first protrusion 212 is located in the first shaft hole 321, and the first protrusion 212 is connected to the hole wall of the first shaft hole 321; in this embodiment, by embedding the first protrusion 212 into the first shaft hole 321, a certain positioning effect can be achieved on the first rotating seat 21, preventing the first rotating seat 21 from detaching from the bottom plate 32 during the rotation process.

[0065] Please refer to Figure 7 , Figure 8 and Figure 9 , in some embodiments, the first protrusion 212 is provided with a first positioning post 2121, and the second rotating seat 23 is provided with a first positioning hole 231 corresponding to the first positioning post 2121; the second rotating seat 23 is sleeved outside the first positioning post 2121 through the first positioning hole 231 to be connected to the first rotating seat 21, so that the first rotating seat 21 can drive the second rotating seat 23 to rotate together when rotating. Among them, the number of the first positioning posts 2121 can be two, and the two first positioning posts 2121 are symmetrically arranged, and two first positioning holes 231 are also provided in the corresponding second rotating seat 23.

[0067] In some embodiments, a second raised portion 322 in the shape of a ring is formed on the edge of the bottom plate 32 around the first shaft hole 321 in the direction close to the cover plate 31; a third raised portion 221 in the shape of a ring is correspondingly formed in the first friction plate 22 in the direction close to the cover plate 31, and the third raised portion 221 covers the second raised portion 322.

[0068] At the same time, a groove is formed on the other side of the bottom plate 32 where the second raised portion 322 is located. The second friction plate 24 is located in the groove, and a part of the corresponding second rotating base 23 is located in the groove. Without the need to provide additional fixing parts, the stability of the connection between the rotating assembly 20 and the base body 30 can be ensured, making the base thinner and improving the reliability of the base structure.

[0069] Please refer to Figure 4 、 Figure 10 and Figure 11 In some embodiments, a limiting member 323 is provided in the bottom plate 32; a corresponding notch groove 214 is provided in the first rotating base 21; when the first rotating base 21 rotates, one end of the notch groove 214 abuts against the limiting member 323. The notch groove 214 is arc-shaped. When the first rotating base 21 rotates, the limiting member 323 in the bottom plate 32 moves along the notch groove 214 like a single hook. When the limiting member 323 moves to one end of the notch groove 214 and abuts against the notch groove 214, the first rotating base 21 cannot continue to rotate, thereby playing a role in restricting the rotation angle of the rotating assembly 20.

[0070] Please refer to Figure 12 In some embodiments, a first gasket 33 is provided on the side of the bottom plate 32 far from the cover plate 31. The number of the first gaskets 33 is multiple, such as six.

Subsequently, the first gasket 33 is disposed around and at the middle position of the bottom plate 32.

[0072] Please refer to Figure 13 , in some embodiments, the bracket assembly 10 includes a fixing strip 11 and at least two support columns 12; when two support columns 12 are provided, the two support columns 12 are respectively fixed at both ends of the fixing strip 11, so that the bracket assembly 10 is in a U shape. At this time, the two support columns 12 can be fixedly connected to the display screen to improve the stability of the connection.

[0073] Of course, in some embodiments, the number of the support columns 12 can also be set to be multiple, and the multiple support columns 12 are evenly spaced on the fixing strip 11. In this embodiment, by increasing the number of the support columns 12, it is convenient to increase the support connection points between the support columns 12 and the display screen, improve the connection stability, and further improve the reliability of the base structure.

[0074] Specifically, one end of the support column 12 is connected to the fixing strip 11, and the other end of the support column 12 is used for installing an external device such as a display screen. A first mounting hole 121 is provided at the other end of the support column 12; two first mounting holes 121 can be provided, one of which is used as a positioning hole to be adapted to a positioning pin to position the display screen, and the other can be used as a fixing hole to be adapted to a screw to install and connect the display screen.

[0075] In some embodiments, a third positioning hole 111 is provided on the fixing strip 11, and a third positioning column 215 corresponding to the third positioning hole 111 is provided on the first rotating seat 21.
