Description

Technical Field

[0001] This utility model relates to the field of performance stage props technology, and in particular to a performance device that assists actors in rotating. Background Technology

[0002] As living standards continue to improve, audiences have higher and higher requirements for the effects of artistic performances. In order to enhance the viewing experience, many stage performances include actors spinning on the stage.

[0003] However, existing actor-led rotation performances rely entirely on the actor's own ability to rotate on stage, which places high demands on the actor and lacks safety guarantees, making it easy for accidents to occur during the rotation process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a performance device that assists actors in rotating. This device is easy to use, greatly reduces the requirements for actors, and can continue to rotate for a long time after a single application of force. It enhances the agility and richness of the performance during the actor's rotation. With the assistance of straps, it enhances the stability of the actor, avoids accidents, and improves the safety and reliability of the performance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A performance device assisting an actor's rotation includes a fixed mounting frame, a rotating mounting frame, a lifting rod, a rotation component, and a positioning component. The fixed mounting frame has a fixed shaft at the bottom center and a fixed platform at the top, with a central circular hole in the center of the platform. The rotating mounting frame is rotatably connected to the fixed shaft at its bottom via the rotation component, and has a rotating platform at its top that matches the contour of the central circular hole. A lifting rod through-hole is provided on the outer periphery of the rotating platform. The lifting rod can move vertically up and down within the lifting rod through-hole, and a first positioning block is fixedly mounted at its bottom, with an upward inclined surface at its end. The positioning assembly is fixed on the upper part of the rotating mounting bracket below the rotating platform, and includes a positioning base, a sliding pin, a second positioning block, a spring, and a lever. The positioning base has a cavity, with one end of the positioning base being an open structure and the other end having a pin hole. The sliding pin is located inside the cavity, with one end fixedly connected to the second positioning block and the other end passing through the pin hole and fixedly connected to the lever. The spring is sleeved on the sliding pin, with both ends abutting against the second positioning block and the positioning base, respectively. The end of the second positioning block has a downward inclined surface. The rotating platform is slightly larger than the length of a person's foot. In the initial state, the fixed platform, rotating platform, and the top plane of the lifting rod are flush with the stage surface. The performance device and stage are integrated for the actors to perform. When the actor performs a self-rotation, the lifting rod is pulled up. After the upper inclined surface of the first positioning block abuts against the lower inclined surface of the second positioning block, the second positioning block, sliding pin, and lever move horizontally. The second positioning block enters the cavity, and the spring is compressed. When the upper inclined surface passes the lower inclined surface, the second positioning block, sliding pin, and lever return to their original positions under the action of the spring. The first positioning block is locked on the second positioning block. The lifting rod extends a certain height beyond the rotating platform (stage surface). One of the actor's feet stands on the rotating platform, and the actor's leg is fixed to the lifting rod by straps to enhance the stability of the actor's self-rotation. After the self-rotation performance is completed, the lever is pulled back to release the lock, and the lifting rod descends back to the initial state.

[0006] Preferably, the rotating platform has a certain number of strap through holes arranged in two rows. When one of the actor's feet is on the rotating platform, the strap through holes are located on both sides of the foot, and the actor's foot can be fixed to the rotating platform by the straps, enhancing the stability of the actor during rotation.

[0007] Preferably, the lifting rod is fitted with a linear bearing, which is fixed to the bottom of the rotating platform.

[0008] Preferably, the lifting rod is provided with several strap loop grooves to limit the straps and prevent the straps from slipping axially on the lifting rod.

[0009] Preferably, the rotary assembly includes a bushing and at least one bearing, the rotating mounting bracket is fixedly connected to the bushing, and the bushing is rotatably connected to the fixed shaft via the bearing.

[0010] Preferably, the number of said lifting rods is two, the corresponding number of said lifting rod through-holes is two, and the number of said first positioning block and said positioning assembly is two groups. The arrangement of the two lifting rods is consistent with two rows of strap through-holes. When an actor stands with one foot on the rotating table, the two lifting rods are located on both sides of the heel and the leg.

[0011] Preferably, the two shifting plates are fixedly connected by a connecting rod, so that the two positioning assemblies can move synchronously.

[0012] Preferably, a long slot through-hole is provided on said rotating table above said shifting plate or said connecting rod. The direction of the long slot through-hole is consistent with the translation direction of the sliding pin, and the shifting plate or the connecting rod can be manually moved backward through the long slot through-hole.

[0013] Preferably, the top ends of the two lifting rods are fixedly connected by a C-shaped connecting rod. The C-shaped connecting rod is in a circular arc shape, and can abut against the actor's leg during use, playing a certain supporting role.

[0014] Preferably, a C-shaped groove matching the contour of the C-shaped connecting rod is provided on said rotating table. The C-shaped groove communicates with the lifting rod through-hole, and when the lifting rod is in the initial position, the C-shaped connecting rod is located in the C-shaped groove, ensuring the flatness of the stage surface.

[0015] Preferably, a limiting groove is provided at the bottom of the fixed mounting frame below said lifting rod. When the lifting rod is in the initial position, the lower end rests in the limiting groove, and the rotating table cannot rotate, ensuring the safety of the actor.

[0016] The advantages of the present utility model are: 1. The performance device of the present utility model assists an actor to rotate on his own, is convenient to use, and greatly reduces the requirements for the actor; 2. It can continue to rotate for a long time after one application of force, which enhances the agility and richness of performance when the actor rotates on his own; 3. The stability of the actor is enhanced with the assistance of the binding straps, avoiding accidents and improving the safety and reliability of the performance; 4. The performance device has a small size, which is only slightly larger than a human's sole, occupies a small stage area, and improves the overall utilization rate of the stage.
