[0002] A turntable is a rotating device installed at the performance location in a performance venue to transport scenery or actors. It serves to highlight the main character and create atmosphere during a stage performance. Turntables vary in structure, including sheet-type turntables, umbrella-shaped turntables, drum-type turntables with built-in lifting platforms, and vehicle-mounted turntables embedded in large mobile platforms. They are widely used in performance venues such as theaters, theatres, and shows. Traditional turntables often use friction wheel transmission, which can lead to low positioning accuracy, demanding installation techniques, high noise levels, limited component compatibility and standardization, and complex maintenance procedures.

Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see the attached Figure 1-7 As shown, the present embodiment provides a thin turntable driven by a synchronous belt 7, comprising a turntable base 1 and a turntable frame body 4. A fixed frame body 2 is installed on the turntable base 1, a fixed frame body 3 is installed on the top of the fixed frame body 2, the fixed frame body 2 is located outside the turntable frame body 4, a turntable frame body 5 is installed on the top of the turntable frame body 4, and the turntable frame body 4 is installed in the middle position of the turntable base 1 through a synchronous belt 7 driving mechanism.

[0023] In this embodiment, the turntable base 1, the rotating platform body 4 and the fixed platform body 2 are all made of steel structures, and the table top of the rotating platform body 4 is a single-layer steel frame.

[0024] Specifically, the synchronous belt 7 drive mechanism includes a driven pulley 6, a synchronous belt 7, a reduction motor 8, a driving pulley 9, a central shaft 18, and a central cylinder 19. The reduction motor 8 and the central cylinder 19 are both fixed to the turntable base 1. The lower portion of the central shaft 18 is rotatably mounted inside the central cylinder 19. The driven pulley 6 is mounted on the upper end of the central shaft 18. The top surface of the driven pulley 6 is fixedly connected to the rotating platform body 4. The driven pulley 6 is connected to the driving pulley 9 through the synchronous belt 7. The driving pulley 9 is mounted on the output shaft of the reduction motor 8. The synchronous toothed belt structure composed of the driven pulley 6, the synchronous belt 7, and the driving pulley 9 avoids slippage during movement from a mechanical perspective and facilitates precise control from an electrical perspective, thereby meeting performance requirements.

[0025] Specifically, the reduction motor 8 and the central cylinder 19 are fixed to the turntable base 1 through a pad 12 .

[0026] Specifically, to ensure the stability of the equipment during movement, it also includes auxiliary support mechanisms. Several auxiliary support mechanisms are arranged in a circular array between the turntable base 1 and the rotating platform body 4. The auxiliary support mechanisms include wheel brackets 10 and support casters 11. The support casters 11 roll in contact with the annular bracket on the rotating platform body 4. The support casters 11 are mounted on the turntable base 1 through the wheel brackets 10. By adjusting the height of the support casters 11 to ensure contact between the casters and the rotating platform body 4, the rotating platform body 4 is fully supported by the central axis 18 and the circumferential support casters 11.

[0027] Specifically, in order to overcome the transmission gap problem caused by the pulling and stretching of the synchronous toothed belt structure during movement, a tensioning mechanism is also included, which includes a first tensioning seat 13, a second tensioning seat 14, a tensioning adjustment nut 15, a limit nut 16, and a tensioning adjustment screw 17. The first tensioning seat 13 is fixed on the mounting seat of the reduction motor 8, and the second tensioning seat 14 is fixed on the pad 12. The tensioning adjustment screw 17 passes through the first tensioning seat 13 and the second tensioning seat 14 in sequence. The tensioning adjustment nut 15 and the limit nut 16 are both threadedly connected to the tensioning adjustment screw 17. The tensioning adjustment nut 15 is located between the first tensioning seat 13 and the second tensioning seat 14, and the second tensioning seat 14 is located between the tensioning adjustment nut 15 and the limit nut 16. When the tensioning mechanism is used to tighten and adjust the synchronous belt 7, the first tensioning seat 13 is moved closer to the second tensioning seat 14 by screwing the limit nut 16, so that the reduction motor 8 drives the active pulley 9 to tighten the synchronous belt 7, and then tighten the tightening adjustment nut 15, and fix the reduction motor 8 to the pad 12 with bolts.

[0028] In the present invention, the driving pulley 9 is driven to rotate by the reduction motor 8, and the driving pulley 9 drives the driven pulley 6 to rotate through the synchronous belt 7, so that the rotating platform body 4 rotates accordingly. The present invention adopts the synchronous belt 7 transmission structure to drive the equipment to rotate. Compared with the friction wheel transmission structure, the present invention simplifies the equipment installation process, improves the equipment transmission efficiency, and improves the equipment transmission accuracy; compared with the gear transmission structure, it reduces the equipment manufacturing and installation costs, and reduces the equipment maintenance costs; the synchronous belt 7 transmission method relies on tooth meshing transmission, with high transmission efficiency, precise transmission ratio, and uniform instantaneous speed. Compared with chain and gear transmission, it has low noise, does not require lubrication, has a wide range of transmission ratios and linear speeds, and is well resistant to impact and vibration. In addition, the synchronous belt 7 is an industrial standard product, which is more convenient and economical in the process of equipment modification and replacement of parts in the later stage of use.

Those skilled in the art may make routine modifications, equivalent substitutions, and improvements within the spirit and principles of the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art and may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments described herein.
