DETAILED DESCRIPTION
[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0023] Example:
[0024] Reference Figure 1-Figure 3The utility model discloses a theater lifting stage, including a base 1, a ring groove 2 is opened on the top side of the base 1, a support ring 3 is rotatably installed in the ring groove 2, the top of the support ring 3 is connected to a bottom cover 4, a bottom ring 5 is fixedly installed in the middle of the bottom side of the bottom cover 4, a driving gear 6 is rotatably installed on the top of the bottom ring 5, two stage panels 7 are arranged on the top side of the bottom cover 4, the stage panels 7 are arranged in a semicircular shape, the sides of the two stage panels 7 are connected to each other and form a circle, a lifting component 8 and a switching component 9 are connected between the bottom side of the stage panel 7 and the bottom side of the bottom cover 4, and a background screen 10 is installed on the top sides of the two stage panels 7.
[0025] In this embodiment, when the stage board 7 is raised or lowered, the lifting assembly 8 is started to cooperate with the driving gear 6 to drive the stage board 7 to move upward, so as to achieve the effect of the stage rising. The provided bottom ring 5 can facilitate the rotation and installation of the driving gear 6. The provided background screen 10 is convenient for changing the environment with the built props. At the beginning of the first performance, the performance can be performed on the stage board 7 facing the audience, and the other stage board 7 is behind the scenes. At this time, the props and environment of the next performance can be arranged, so that the arrangement time of the scene props is more sufficient and the probability of failure in the arrangement of props and environment is reduced. After the first performance ends, the provided lifting assembly 8 can be used to cooperate with the switching assembly 9 to rotate the arranged stage board 7 to the direction of the audience, so that the audience can quickly watch the next performance and reduce the waiting time of the audience.
[0026] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the lifting assembly 8 includes a number of bottom cavity rods 11, and the plurality of bottom cavity rods 11 are distributed in a circular array and rotatably installed on the inner bottom side of the bottom cover 4. A gear ring 12 is fixedly connected to the bottom side of the outer peripheral wall of the bottom cavity rod 11, and the gear ring 12 is meshed with the driving gear 6. A threaded rod 13 is threadedly connected to the top end of the bottom cavity rod 11. An arc groove 14 is provided on the bottom side of the stage board 7 at the threaded rod 13. The top end of the threaded rod 13 extends into the arc groove 14 and fits with the inner wall of the arc groove 14. An inner groove 15 is provided on the top side of the base 1. A driving motor 16 is installed in the inner groove 15. The output end of the driving motor 16 is connected to an output shaft 17. The top end of the output shaft 17 passes through the bottom cover 4 and the driving gear 6 and extends to the top of the driving gear 6. A first electromagnetic lock 18 is installed on the top side of the driving gear 6.
[0027] In this embodiment, when lifting, the first electromagnetic lock 18 is opened, and the first electromagnetic lock 18 will be adsorbed on the output shaft 17. A gap is left between the driving gear 6 and the output shaft 17 to facilitate the drive of the switching component 9. When the stage is lifted, the first electromagnetic lock 18 adsorbs the output shaft 17. At this time, when the driving motor 16 drives the output shaft 17 to rotate, it will drive the driving gear 6 to rotate. When the driving gear 6 rotates, it will drive each gear ring 12 meshing with it to rotate, and then it will drive the bottom cavity rod 11 to rotate. When the bottom cavity tube rotates, the threaded rod 13 threadedly connected to it will rise, thereby pushing the stage board 7 to move upward. After the performance, the driving motor 16 is started again, and the stage board 7 is restored to its original height by reversing the driving motor 16. Then the first electromagnetic lock 18 is closed, and the scene is changed by switching the driving motor 16 and the output shaft 17. Therefore, when in use, the stage board 7 can be driven to rise and fall by the switch of the driving motor 16 and the first electromagnetic lock 18, so as to achieve the effect of lifting and lowering the lifting board to cooperate with the performance.
[0028] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the switching assembly 9 includes a bottom column 19, which is fixedly installed on the bottom side of the connection between the two stage panels 7, and a gap is left between the top end of the output shaft 17 and the bottom end of the bottom column 19. Two second electromagnetic locks 20 are installed on the bottom side of the bottom column 19, and the two second electromagnetic locks 20 are arc-shaped. The inner curvature of the second electromagnetic lock 20 is the same as the curvature of the outer wall of the output shaft 17.
[0029] In this embodiment, when switching the stage panel 7, the first electromagnetic lock 18 is closed and the second electromagnetic lock 20 is opened. Then the first electromagnetic lock 18 loses its magnetism, releasing the connection between the drive gear 6 and the output shaft 17. The second electromagnetic lock 20 will be adsorbed on the output shaft 17. At this time, after the drive motor 16 is started, it will drive the rotation of the base column 19, and then drive the rotation of the stage panel 7. The arc groove 14 is set on the threaded rod 13, and the threaded rod 13 is used to limit the position to prevent displacement during rotation. As the drive motor 16 rotates, the two stage panels 7 will switch positions, so as to achieve the purpose of rotating and moving the pre-prepared scene props to a position facing the audience, reducing the time for scene arrangement and the time for the audience to wait.
[0030] In a further preferred embodiment of the present invention, Figure 2-3 As shown, an inner groove 21 is provided on the top side of the peripheral wall of the bottom cover 4, a limiting ring 22 is slidably connected in the inner groove 21, the top side of the limiting ring 22 is arranged in a flared shape, and the top side of the inner peripheral wall of the limiting ring 22 is fixedly connected to the stage panel 7.
[0031] The implementation principle of the above embodiment is: the inner groove 21 and the limit ring 22 provided therein limit the stage panel 7 to prevent the stage panel 7 from shifting when it is raised, and can prevent the shifting when the performers perform on the stage panel 7, thereby improving stability.
[0032] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
