As a further improvement of the invention, the guide plate is arranged in parallel with the inclined surface of the large cone pulley.

The beneficial effects of the invention are as follows:

the invention can automatically realize that the performer finishes the set dance movements around the dancer through the mechanized operation, has low requirements on the level, the mercy and the rhythm sense of the performer, has strong personnel interchangeability, can replace the performer at any time, is favorable for coping with various emergency conditions, has simple structure and convenient use, can realize the adjustment of different movement speeds of the performer, and greatly improves the stage performance effect.

Drawings

The invention will be further described with reference to the drawings and examples.

FIG. 1 is a front view of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1 at I;

fig. 3 is a top view of the present invention.

Detailed Description

The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.

As shown in fig. 1 to 3, a variable speed rotary entertainment stage comprises a bottom plate 1, a mounting column 2 is fixed on the bottom plate 1, a large conical wheel 3 is mounted on the mounting column 2 through a bearing, four sliding rods 4 sliding along the radial direction of the large conical wheel 3 are arranged on the large conical wheel 3 at equal intervals, a track disc 5 is fixed at the top of the mounting column 2, an oval groove 5a matched with the sliding rod 4 is formed in the track disc 5, a round small stage 6 placed horizontally is fixed at one end, far away from the track disc 5, of the sliding rod 4, and a variable speed driving device 7 is connected to the large conical wheel 3.

The variable speed driving device 7 comprises a small conical wheel 71 in friction transmission fit with the large conical wheel 3, a driving motor 72 connected with the small conical wheel 71, a guide plate 73 in sliding fit with the driving motor 72 and arranged obliquely upwards and rightwards, a vertical plate 74 fixed on the bottom plate 1, a screw rod 75 arranged on the vertical plate 74, a sliding sleeve 76 sleeved on the screw rod 75 and rotatable, and a connecting rod 77 with one end hinged on the sliding sleeve 76 and the other end hinged on the driving motor 72, wherein a shoulder protruding part 75a is arranged at the joint of the screw rod 75 and the sliding sleeve 76.

The guide plate 73 is provided with a long chute 73a, and a rectangular slide block 72a matched with the long chute 73a is fixed at the bottom of the driving motor 72.

The connecting rod 77 is arranged obliquely upward from left to right. In this way, the tilt arrangement is such that the screw 75, when rotated, is able to drag the drive motor 72.

The guide plate 73 is arranged in parallel with the inclined plane of the large cone pulley 3. In this way, the small cone pulley 71 is constantly ensured to contact the large cone pulley 3 as the small cone pulley 71 slides along the guide plate 73, and the radius of contact with the large cone pulley 3 is constantly changed during the sliding, thereby changing the transmission speed to the large cone pulley 3.

The method of use of the invention is further described below:

when the four-stage device works, a dancer is positioned on the track disc 5 to perform, the dancer stands on the corresponding small circular stages 6 respectively, the driving motor 72 drives the small conical wheels 71 to rotate, the large conical wheels 3 are driven to move through friction transmission, the sliding rods 4 arranged on the large conical wheels 3 move back and forth along the track of the elliptical grooves 5a while rotating, and finally the four-stage device realizes the rotation and the mutual approaching or separating movement of the four small circular stages 6 around the central dancer, so that the expected stage effect is achieved.

During this time, the screw 75 is rotated to the right so that the slide sleeve 76 pushes the link 77 to swing clockwise, and the driving motor 72 is moved obliquely upward along the guide plate 73 via the rectangular slide block 72a so that the radius value of the large cone pulley 3 contacted by the small cone pulley 71 is increased, the speed of the large cone pulley 3 is reduced, and thus the speed of the performer is reduced, and the speed of the performer can be increased by the opposite operation.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
