[0002] A drone refers to an unmanned aircraft, which is an unmanned aircraft controlled by radio remote control equipment and a self-contained program control device. It can be divided into military and civilian applications according to its application field. Civilian drones are mostly displayed in the form of exhibitions, and are usually displayed using exhibition stands.

[0003] Existing exhibition stands for displaying drones usually display drones statically, requiring visitors to actively circle around the drones to observe them. It is impossible to display the drones dynamically through actions such as rotation and lifting, which makes the drones less vivid during display and inconvenient for visitors to watch the drones. In addition, when the existing stands are connected and fixed to the drones, they are usually fixed through a single vertical rod-shaped structure, which reduces the area where the drone is connected to the stand, making the drone model more likely to shake when touched by external forces, which is not conducive to keeping the drone stable on the stand. Utility Model Content

[0023] like Figures 1 to 4As shown, the rotating exhibition stand for displaying a drone in this embodiment includes a chassis 8. The chassis 8 is a circular disc-shaped structure made of a heavy metal material, so that the center of gravity of the stand falls on the chassis 8 to increase the overall stability of the stand. A rotating disk 7 is provided on the top of the chassis 8. The diameter of the rotating disk 7 is the same as the diameter of the chassis 8. At the same time, the rotating disk 7 can be rotated on the top of the chassis 8, thereby driving the drone fixed on the top of the stand to be displayed in a rotating manner. A sleeve column 5 is fixedly connected to the top of the rotating disk 7. A cavity is opened inside the sleeve column 5 for installing and fixing the electric push rod 10. At the same time, the inner diameter of the cavity of the sleeve column 5 is adapted to the outer diameter of the vertical rod 3, so that the vertical rod 3 can be rotated. In order to slide up and down smoothly on the top of the sleeve column 5, a vertical rod 3 is provided on the top of the sleeve column 5, and the vertical rod 3 is made of lightweight material. A circular plate 1 is provided on the top of the vertical rod 3. The two side walls of the circular plate 1 are fixedly connected with an extension plate 2. Holes are provided on the extension plate 2 for fixing with bolts at the interface at the bottom of the drone, so that the drone can be firmly fixed on the circular plate 1 and the extension plate 2. The bottom end of the extension plate 2 is fixedly connected with an oblique support rod 9, which can transmit the gravity exerted on the extension plate 2 to the sleeve ring, so that the force exerted on the top of the bracket can be transmitted to the sleeve column 5, thereby facilitating the drone to remain stable at the top of the bracket. A slip ring 6 is movably sleeved on the outer wall of the sleeve column 5, and the inner diameter of the slip ring 6 is consistent with that of the sleeve column 5. The outer diameters are adapted, and the inner wall of the slip ring 6 is smooth, so that the slip ring 6 can slide up and down smoothly on the surface of the sleeve column 5, so as to facilitate the diagonal support rod 9 to maintain the stability of the extension plate 2 and the circular plate 1 through the slip ring 6. The bottom end of the rotating disk 7 is fixedly connected with a bottom column 13. The function of the bottom column 13 is to enable the bottom end of the rotating disk 7 to maintain connection with the inside of the chassis 8, thereby increasing the stability of the rotating disk 7 during rotation. The outer wall of the bottom column 13 is sleeved with a gear ring 12, and the outer side wall of the gear ring 12 is movably meshed with an external gear 16. The gear ring 12 and the external gear 16 can drive the rotating disk 7 to rotate on the top of the chassis 8 by meshing. Compared with directly using the rotating motor 14 to drive the rotation As for the way the disk 7 rotates, this way is more stable during rotation, and it is not easy for the rotating disk 7 to rotate at will. A rotating motor 14 is fixedly installed inside the chassis 8, and a side wall of the rotating motor 14 is electrically connected to a controller 15. The function of the controller 15 is to control the electric push rod 10 and the rotating motor to start in coordination, so that the bracket can be raised and lowered while rotating, thereby facilitating the dynamic display of the drone on the bracket. A plurality of round beads 11 are movably embedded at the top of the chassis 8. The surface of the round beads 11 is smooth, and the top is in contact with the bottom of the rotating disk 7, which can reduce the friction force of the rotating disk 7 when it rotates on the top of the chassis 8, thereby making it more conducive to the rotation of the rotating disk 7.

[0024] Specifically, a threaded hole 17 is provided at the top of the vertical rod 3, and the inner wall of the threaded hole 17 is threaded with an external threaded tube 18, so that the circular plate 1 can be removed from the vertical rod 3 through the threaded hole 17, thereby facilitating the assembly and docking of the circular plate 1 and the extension plate 2 with the drone.

[0025] Furthermore, the external threaded tube 18 is fixedly connected to the circular plate 1, and the circular plate 1 is movably connected to the vertical rod 3 through the external threaded tube 18, so that the circular plate 1 and the extension plate 2 can be separated from the vertical rod 3, which is convenient for replacing the deformed circular plate 1 and the extension plate 2.

[0026] Furthermore, a limit ring 4 is provided on the top movable threaded sleeve of the sleeve column 5, and an electric push rod 10 is fixedly installed inside the sleeve column 5. The electric push rod 10 is electrically connected to the controller 15. The function of the limit ring 4 is to prevent the electric push rod 10 from pushing the vertical slip ring 6 and the top of the sleeve column 5 out, thereby limiting the slip ring 6 and preventing the slip ring 6 from accidentally detaching from the sleeve column 5.

[0027] Furthermore, the output end of the electric push rod 10 is engaged and connected with the vertical rod 3, and the vertical rod 3 is movably connected with the sleeve column 5 through the electric push rod 10. The electric push rod 10 pushes the vertical rod 3 up and down, so that the vertical rod 3 can be raised and lowered in the sleeve column 5, thereby realizing the dynamic display of the drone on the bracket.

[0028] Furthermore, the bottom end of the diagonal support rod 9 is fixedly connected to a side wall of the slip ring 6, and the diagonal support rod 9 is movably connected to the sleeve column 5 through the slip ring 6. The two diagonal support rods 9, the extension plate 2 and the slip ring 6 can form a stable triangular structure, so that the force at the top of the bracket can be transmitted to the middle and bottom of the bracket, thereby increasing the stability of the drone at the top of the bracket.

[0029] Furthermore, the output end of the rotating motor 14 is connected through the middle of the external gear 16, the bottom column 13 is movably connected to the chassis 8, the rotating disk 7 is rotatably connected to the chassis 8 through the bottom column 13, and the external gear 16 can be driven by the rotating motor 14 to rotate, thereby realizing the bottom column 13 driving the rotating disk 7 to rotate on the top of the chassis 8, realizing the rotating display of the drone.

[0030] The method of using this embodiment is as follows: when using the rotary exhibition stand for displaying the drone, the circular plate 1 can be firstly twisted so that the external threaded barrel 18 at the bottom end of the circular plate 1 is screwed out from the threaded hole 17 at the top end of the vertical rod 3, so that the circular plate 1 and the extension plate 2 and the collar are separated from the vertical rod 3 and the collar respectively, and then the circular plate 1 and the extension plate 2 can be assembled and docked with the bottom end of the drone, and then the collar and the external threaded barrel 18 can be reset, and then the limit ring 4 is fastened to the top of the sleeve column 5, and the drone is fixed at the top of the stand. At this time, the stand can be connected to an external power supply, so that the controller 15 and the rotary motor and the electric push rod 10 are energized, so that the rotary motor drives the external gear 16 to rotate, drives the external gear 16 to engage the gear ring 12 to rotate, drives the bottom column 13 to rotate in the bottom box, and drives the rotating disk 7 to rotate at the top of the chassis 8 through the ball 11, and at the same time the electric push rod 10 will push the vertical rod 3 to move up and down at the top of the sleeve column 5, so that the drone can be raised and lowered while rotating on the stand, so that the drone can be dynamically displayed, so that visitors can better watch the drone.
