Description

Technical Field

[0001] This utility model relates to the field of stage props and scenery technology, specifically to a convenient stage props and scenery rotation device. Background Technology

[0002] Stage props and scenery refer to the physical elements that constitute the visual environment of a performance. The artistic images created by stage props and scenery are conceived and designed by designers according to the requirements of the plot. They are shaped and molded using stage technology so that they can be reflected in the performance. Together with lighting, makeup, costumes, etc., they comprehensively shape the external image of the performance, help the actors perform, and express the content of the script.

[0003] The published patent document CN216109958U discloses a liftable and rotating stage based on stage props. This published patent document uses a first hydraulic cylinder that is tilted and installed between a limiting plate and a base plate to support the limiting plate, making the stage plate rotate more smoothly. A second hydraulic cylinder extends to lift the base plate, raising the support legs off the bottom surface. The base plate is supported by the second hydraulic cylinder and the moving wheels, and the stage can be moved by the moving wheels. After the movement is completed, the second hydraulic cylinder retracts synchronously, that is, the stage is supported by the support legs again. However, the above-mentioned published patent document cannot divide the stage into independent performance areas and scenery areas. The scenery needs to be set up for the next performance after the performance ends, resulting in low performance efficiency. Utility Model Content

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-3 This utility model provides a convenient stage prop and scenery rotation device, including a stage board 1 and a circular base 2. The stage board 1 is set above the circular base 2, and the prop and scenery tent 3 is symmetrically fixedly connected to the front and rear sides of the top of the stage board 1. A support rod 4 is fixedly connected inside the circular base 2. A vertical shaft 5 is rotatably installed through the middle of the support rod 4, and a servo motor 6 is fixedly installed at the top of the support rod 4. The upper end of the vertical shaft 5 is fixedly installed to the bottom of the stage board 1, and a large gear 7 is sleeved and fixedly connected to the lower side of the vertical shaft 5. A rotating shaft 8 is fixedly installed at the output end of the servo motor 6, and a small gear 9 is sleeved and fixedly connected to the rotating shaft 8. The small gear 9 meshes with the large gear 7.

[0023] In this technical solution, the servo motor 6 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the vertical shaft 5 to rotate at a reduced speed through the small gear 9 and the large gear 7, thereby driving the stage board 1 to rotate at a reduced speed. This facilitates the operation of rotating the two prop and scenery tents 3 on the top of the stage board 1. The rotation is more stable, so that the performance in one prop and scenery tent 3 can be carried out without affecting the prop and scenery setup in the other prop and scenery tent 3, thus increasing the performance efficiency.

[0024] In some technical solutions, such as Figure 2-5 As shown, positioning ears 10 are symmetrically fixedly connected to both sides of the circular base 2. Positioning ears 10 are provided with positioning holes 16. A photoelectric generator 17 is fixedly installed on the top of the positioning ears 10. Electric cylinders 20 and photoelectric sensors 21 are fixedly installed on both sides of the bottom of the stage board 1. A positioning shaft 22 that matches the positioning hole 16 is fixedly installed at the output end of the electric cylinder 20. The photoelectric sensor 21 is adapted to the photoelectric generator 17.

[0025] In use, the position determination function between the photoelectric generator 17 and the photoelectric sensor 21 can detect whether the rotation angle of the stage board 1 is in place. Furthermore, by driving the positioning shaft 22 through the positioning hole 16 via the electric cylinder 20, the rotated stage board 1 can be fixed to prevent the stage board 1 from rotating and deviating during the performance.

[0026] In some technical solutions, such as Figure 3-4 As shown, the top of the circular base 2 is provided with an annular limiting groove 18, and both sides of the bottom of the stage board 1 are fixedly connected with limiting shafts 19. The lower end of the limiting shaft 19 is inside the annular limiting groove 18, and the limiting shaft 19 is adapted to the annular limiting groove 18.

[0027] During use, the limiting action of the limiting shaft 19 and the annular limiting groove 18 ensures the stability of the stage board 1 during rotation.

[0028] In some technical solutions, such as Figure 2-3 As shown, four mounting feet 11 are fixedly connected at equal intervals along the outer edge of the bottom of the circular base 2, and mounting holes 12 are provided on the mounting feet 11.

[0029] When in use, the device can be easily fixed to the stage floor through the mounting holes 12 on the mounting feet 11.

[0030] In some technical solutions, such as Figure 2-3 As shown, several internally threaded sleeves 13 are fixedly connected at equal intervals to the bottom of the circular base 2, and the internal threads of the internally threaded sleeves 13 are connected to matching threaded shafts 14.

[0031] In use, the height of the threaded shaft 14 can be adjusted by rotating the threaded shaft 14 to provide support and reinforcement for various positions of the annular base 2.

[0032] In some technical solutions, such as Figure 2-3 As shown, a rubber pad 15 is fixedly connected to the lower end of the threaded shaft 14.

[0033] During use, the rubber pad 15 prevents wear between the threaded shaft 14 and the ground.

[0034] Working principle: During installation, the device is fixed to the stage floor through the mounting holes 12 on the mounting feet 11. Then, the threaded shaft 14 is rotated to adjust its position inside the internal threaded sleeve 13, and the height of the threaded shaft 14 is adjusted so that the rubber pad 15 contacts the stage floor to support and reinforce the various positions of the ring base 2. During use, the servo motor 6 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the vertical shaft 5 to rotate at a reduced speed through the small gear 9 and the large gear 7, thereby driving the stage board 1 to rotate at a reduced speed, making the rotation smoother and easier to operate. The two prop and scenery tents 3 on the top of the stage board 1 can be rotated, so that the performance in one prop and scenery tent 3 can be carried out without affecting the prop and scenery setup in the other prop and scenery tent 3. When the stage board 1 rotates, the photoelectric generator 17 and the photoelectric sensor 21 can detect whether the rotation angle of the stage board 1 is in place. The electric cylinder 20 drives the positioning shaft 22 through the positioning hole 16 to fix the rotated stage board 1, preventing the stage board 1 from rotating and deviating during the performance.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
