They cannot be split according to the size and shape of the venue, have a small range of applications, and present a relatively simple stage performance effect. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multifunctional multi-ring nested rotary table, comprising a base and several concentrically arranged annular platforms rotatably mounted on the base. Each annular platform has a concentric ring seat coaxially arranged at its bottom, and the inner and outer walls of the concentric ring seat are respectively provided with internal and external tooth grooves. Several rotating rings are rotatably mounted on the base, and the rotating rings are coaxially arranged with the annular platforms and located between the concentric ring seats of two adjacent annular platforms. Several planetary gears are rotatably mounted on the rotating rings, and the planetary gears are respectively meshed with the internal and external tooth grooves of the two coaxially arranged annular platforms. Several horizontal side mounting plates are arranged around the rotating rings, and the side mounting plates are respectively equipped with a first locking unit for fixing the rotating rings and a second locking unit for fixing the rotating rings and the annular platforms.

[0005] To ensure stable and smooth rotation of each annular platform, the following features are specifically provided: the base is provided with annular slide rails of the same number as the annular platforms, and the annular platforms are rotatably mounted on the annular slide rails.

[0006] To ensure stable and smooth rotation of the rotating ring, the following features are specifically provided: the annular slide rail is provided with mounting grooves for rotatably mounting the rotating ring.

[0008] To ensure that the pressure direction of the first top column is perpendicular to the axis of the annular slide rail, the following feature is specifically designed: the working end of the first linear actuator moves radially along the annular slide rail.

[0009] To ensure that the first top post can be effectively inserted into the side slot and contact its inclined surface to achieve engagement, the following features are specifically designed: the outer diameter of the first top post is smaller than the maximum opening width of the side slot and larger than the minimum opening width of the side slot.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 7 : A multifunctional multi-ring nested rotary table includes a base 1 and several concentrically arranged annular platforms 2 rotatably mounted on the base 1. Each annular platform 2 has a concentric ring seat 2a coaxially arranged at its bottom. The inner and outer walls of the concentric ring seat 2a are respectively provided with an inner tooth groove 2a1 and an outer tooth groove 2a2. Several rotating rings 3 are rotatably mounted on the base 1. The rotating rings 3 are coaxially arranged with the annular platforms 2 and are located between the concentric ring seats 2a of two adjacent annular platforms 2. Several planetary gears 3a are rotatably mounted on the rotating rings 3. The planetary gears 3a are respectively meshed with the inner tooth groove 2a1 and the outer tooth groove 2a2 of the two coaxially arranged annular platforms 2. Several horizontal side mounting plates 3b are arranged around the rotating rings 3. The side mounting plates 3b are respectively equipped with a first locking unit 3c for fixing the rotating rings 3 and a second locking unit 3d for fixing the rotating rings 3 and the annular platforms 2.

[0025] In this application, the rotating platform has a base 1 that provides mounting support for the entire device. Several concentrically arranged annular platforms 2 are rotatably assembled onto the base 1 via concentric ring seats 2a at the bottom, forming a multi-ring nested concentric rotating platform. This embodiment only shows the installation effect of two annular platforms 2. The rotating ring 3 is located between the concentric ring seats 2a of two adjacent annular platforms 2, and the planetary gear 3a on the rotating ring 3 is always meshed with the inner tooth groove 2a1 and outer tooth groove 2a2 of the two coaxial annular platforms 2. In the initial state, the first locking unit 3c fixes the rotating ring 3 to the base 1, and the second locking unit 3d releases the locking between the rotating ring 3 and the corresponding annular platform 2. In this state, when any one of the annular platforms 2 is driven to rotate by a motor, the planetary gear 3a is driven to rotate on the rotating ring 3 through the inner tooth groove 2a1 or the outer tooth groove 2a2, thereby driving the adjacent annular platforms 2 to achieve reverse linkage rotation; thus, the performers standing on different annular platforms 2 rotate in opposite directions. When the second locking unit 3d fixes the rotating ring 3 to one of the annular platforms 2, the first locking unit 3c releases the lock between the rotating ring 3 and the base 1. At this time, when the motor drives any one of the annular platforms 2 to rotate, it drives the rotating ring 3 to rotate synchronously. The planetary gear 3a moves with the rotating ring 3 and maintains meshing with the inner tooth groove 2a1 and outer tooth groove 2a2 of the two annular platforms, thus driving the other annular platform 2 to rotate synchronously in the same direction. In this embodiment, the motor used to drive the rotation of the annular platform 2 can be connected to any one of the annular platforms, so it is not shown in the figure. This embodiment, through the cooperation of several concentrically arranged annular platforms 2, rotating ring 3 and planetary gear 3a, can adapt to the size requirements of the turntable required for different venues, solving the problem of the limited applicability of the existing integral structure of the turntable. The combination of the first locking unit 3c and the second locking unit 3d can flexibly realize different motion modes of independent rotation of the annular platform 2 and multi-ring reverse rotation using only a single power source, breaking the limitation of the existing turntable's unidirectional rotation and enriching the presentation of stage performances.

[0026] like Figure 5 As shown, in order to ensure that each annular platform 2 rotates stably and smoothly, the following features are specifically designed: The base 1 is provided with the same number of annular slide rails 1a as the annular platform 2, and the annular platform 2 is rotatably installed at the annular slide rail 1a.

[0027] like Figure 2 and Figure 5 As shown, in order to ensure the smooth and stable rotation of the rotating ring 3, the following features are specifically designed: The annular slide rail 1a is provided with a mounting groove 1b for rotating the rotating ring 3.

[0028] To achieve the fixation of the rotating ring 3, the following features are specifically designed: The annular slide rail 1a is provided with a side groove 1a1 surrounding the outer wall of the annular slide rail 1a. The side groove 1a1 has an opening that increases radially outward along the annular slide rail 1a. The first locking unit 3c includes a first linear driver 3c1 mounted on one of the side mounting plates 3b, and a first top post 3c2 mounted on the working end of the first linear driver 3c1. The first linear driver 3c1 drives the first top post 3c2 to insert into the side groove 1a1 to lock the position of the rotating ring 3 in the mounting groove 1b.

[0029] like Figure 3 As shown, in this embodiment, when it is necessary to fix the rotating ring 3, the first linear actuator 3c1 mounted on the side mounting plate 3b is activated, driving the first top post 3c2 at its working end to extend radially outward along the annular slide rail 1a. Since the side slot 1a1 has an opening that increases radially outward along the annular slide rail 1a, the first top post 3c2 can be smoothly and accurately inserted into the side slot 1a1 surrounding the outer wall of the annular slide rail 1a. Through the mechanical engagement of the first top post 3c2 and the side slot 1a1, the rotational freedom of the rotating ring 3 within the mounting groove 1b is restricted, thus achieving a stable fixation of the rotating ring 3. When it is necessary to unlock the rotating ring 3 to allow it to rotate again, the first linear actuator 3c1 reverses its action, causing the first top post 3c2 to retract from the side slot 1a1, allowing the rotating ring 3 to rotate flexibly within the mounting groove 1b. In this embodiment, the first linear actuator 3c1 can be an electric push rod with an independent power supply. The linear drive mechanism of the first linear actuator 3c1 and the first top column 3c2 enables rapid response and reliable fixation of the locking and unlocking of the rotating ring 3, avoiding loosening during the locking process and further ensuring the realization of the multi-ring linkage reverse rotation mode of the annular platform 2.

[0030] like Figure 3 As shown, in order to ensure that the pressure direction of the first top column 3c2 is perpendicular to the axis of the annular slide rail 1a, the following features are specifically designed: The working end of the first linear actuator 3c1 moves radially along the annular slide rail 1a.

[0031] like Figure 3 As shown, in order to ensure that the first top post 3c2 can be effectively inserted into the side slot 1a1 and contact its inclined surface to achieve engagement, the following features are specifically designed: The outer diameter of the first top post 3c2 is smaller than the maximum opening width of the side slot 1a1 and larger than the minimum opening width of the side slot 1a1.

[0032] To ensure that the rotating ring 3 rotates synchronously with the annular platform, the following features are specifically designed: The bottom of the concentric ring seat 2a is provided with an arc-shaped slot 2a3; the second locking unit 3d includes a second linear driver 3d1 fixedly installed on one of the side mounting plates 3b, and a second top post 3d2 installed on the working end of the second linear driver 3d1. When the second linear driver 3d1 drives the second top post 3d2 to move vertically and insert into the arc-shaped slot 2a3, the rotating ring 3 rotates synchronously with the annular platform 2.

[0033] like Figure 4 and Figure 7 As shown, in this embodiment, when it is necessary to achieve synchronous rotation between the rotating ring 3 and the annular platform 2, the first locking unit 3c engages to lock the rotating ring 3, and the second linear actuator 3d1, fixed on the mounting plate 3b on the other side, is activated, driving the second top post 3d2 at its working end to move vertically and insert into the pre-set arc-shaped slot 2a3 at the bottom of the concentric ring seat 2a. At this time, the rotation of the annular platform 2 will drive the second top post 3d2 to rotate synchronously through the arc-shaped slot 2a3, thereby driving the rotating ring 3 to rotate synchronously with the annular platform 2 in the same direction and at the same speed within the mounting groove 1b. This embodiment, through the arc-shaped slot 2a3 at the bottom of the concentric ring seat 2a, combined with the vertical movement of the second top post 3d2, avoids interference with the radial movement of the annular platform 2 and achieves efficient power transmission, ensuring the coaxiality and speed consistency of the rotating ring 3 and the annular platform 2 when rotating synchronously.

[0034] To ensure that the second top post 3d2 is inserted into the arc-shaped slot 2a3 in a timely and accurate manner, the following features are specifically designed: The second locking unit 3d also includes a ranging sensor 3d3 fixedly installed on one side of the second top column 3d2. The working end of the ranging sensor 3d3 is vertically upward and aligned with the bottom of the concentric ring seat 2a. The ranging sensor 3d3 is located within the moving path of the arc-shaped slot 2a3. The ranging sensor 3d3 is connected to the second linear driver 3d1 via a controller.

[0035] like Figure 6 and Figure 7As shown, in this embodiment, the distance sensor 3d3, fixed to one side of the second top post 3d2, is always in working condition. Its vertically upward-facing working end is aligned with the bottom of the concentric ring seat 2a and located within the moving path of the arc-shaped slot 2a3, continuously detecting the distance to the bottom of the concentric ring seat 2a. When the annular platform 2 rotates to a preset synchronous position, and the arc-shaped slot 2a3 moves with the concentric ring seat 2a to the position corresponding to the second top post 3d2, the distance value detected by the distance sensor 3d3 increases, and is then transmitted to the controller via a signal. After receiving the signal, the controller quickly issues a command to start the second linear driver 3d1 mounted on the side mounting plate 3b, driving the second top post 3d2 at its working end to move precisely in the vertical direction and smoothly insert into the arc-shaped slot 2a3. This embodiment achieves automated and precise control of the insertion action of the second top post 3d2 by coordinating the length of the arc-shaped slot 2a3 with the distance sensor 3d3, ensuring that the second top post 3d2 is inserted in time when the arc-shaped slot 2a3 moves to the corresponding position.

[0036] Working principle: In the initial state, the first locking unit 3c fixes the rotating ring 3 to the base 1, and the second locking unit 3d releases the rotating ring 3 from the corresponding annular platform 2. In this state, when the motor drives any one of the annular platforms 2 to rotate, the adjacent annular platforms 2 rotate in opposite directions; thus, performers standing on different annular platforms 2 rotate in opposite directions. When the second locking unit 3d fixes the rotating ring 3 to one of the annular platforms 2, and the first locking unit 3c releases the rotating ring 3 from the base 1, when the motor drives any one of the annular platforms 2 to rotate, it can drive the other annular platform 2 to rotate synchronously in the same direction.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
