DETAILED DESCRIPTION

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] The present embodiment provides a rotating bracket, including an outer shaft tube 1, a rotating clamp 21, a rotating clamp 22 and a rotating support 3, wherein the rotating clamp 21 and the rotating clamp 22 are arc-shaped, and the rotating clamp 21 and the rotating clamp 22 are respectively fixedly mounted on the rotating support 3, and the outer shaft tube 1 is provided with an upper notch 41 and a lower notch 42 on the tube wall, and the width of the upper notch 41 and the lower notch 42 is smaller than the maximum width of the rotating clamp 1 21 and the rotating clamp 2 22, and the rotating clamp 1 21 and the rotating clamp 2 22 are respectively inserted into the upper notch 41 and the lower notch 42 of the outer shaft tube 1. The upper notch 41 and the lower notch 42 are both U-shaped notches, and the two open ends of the two U-shaped notches are respectively arranged at the upper and lower ends of the outer shaft tube 1, and the rotating clamp 1 21 and the rotating clamp 2 22 are installed in the outer shaft tube 1 from the above two open ends. The end cover 7 is used to close the upper end opening of the outer shaft tube 1 to prevent dust from falling in.

[0023] Specifically, an arcuate clamping surface 32 is provided on the rotating support 3 in a direction corresponding to the rotating clamp 1 21 and the rotating clamp 2 22. A gap is formed between the rotating clamp 1 21 and the rotating clamp 2 22 and the arcuate clamping surface 32, allowing the rotating support 3, the rotating clamp 1 21, and the rotating clamp 2 22 to rotate along the wall of the outer shaft tube 1 through the gap. The rotating clamp 1 21 and the rotating clamp 2 22 are respectively fixedly mounted on the rotating support 3 in a detachable manner by screwing or clamping. In this embodiment, the rotation of the rotating clamp 1 21, the rotating clamp 2 22, or the rotating support 3 is driven by a motor. Since motor drive is common knowledge in the art, it will not be described in detail here.

[0024] The rotating support 3 is provided with a load-bearing frame 31, which is fixedly connected to the rotating support 3 and arranged radially along the circular section of the outer shaft tube 1. The load-bearing frame 31 is provided with a power socket 33 for connecting the display supported by the load-bearing frame 31 to an external power supply.

[0025] In addition, an inner shaft tube 6 coaxial with the outer shaft tube 1 is provided inside the outer shaft tube 1, an inner curtain opening 61 is opened on the inner shaft tube 6 along the length direction, a rolling curtain 5 is installed in the inner shaft tube 6, an outer curtain opening 11 corresponding to the position of the inner curtain opening 61 is opened on the outer shaft tube 1, and the rolling curtain 5 protrudes from the outer curtain opening 11 and the inner curtain opening 61.

[0026] Working principle:

[0027] The items to be displayed, such as a display, are mounted on the load-bearing frame 31 of the rotating support 3. When the rotating support 3 rotates, the display is driven to rotate, thereby realizing the display requirements of the display in different directions. When the motor drives the rotating clamp 1 21 and the rotating clamp 2 22 to rotate, since the rotating clamp 1 21 and the rotating clamp 2 22 are both fixedly connected to the rotating support 3, and the widths of the upper notch 41 and the lower notch 42 are both smaller than the maximum widths of the rotating clamp 1 21 and the rotating clamp 2 22, the rotating clamp 1 21 and the rotating clamp 2 22 will not fall off from the upper notch 41 or the lower notch 42. Here, the connection portion between the rotating clamp 1 21 and the rotating clamp 2 22 and the rotating support 3 limits the left and right rotation angles of the rotating clamp 2. At this time, the inner shaft tube 6 and the outer shaft tube 1 are both stationary, and the roller blind 5 can be opened or tightened from the outer curtain opening 11 and the inner curtain opening 61.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
