Description

Technical Field

[0001] The present invention relates to an amusement facility, in particular to a rotating machine, and is suitable for indoor amusement rotating machines. Background Art

[0002] Amusement carousels are commonly used in amusement facilities in kindergartens, children's amusement centers and other places. The lower motor drives the upper rotating rod to rotate, and players play the game by jumping and avoiding the rotating rod. The rotating rod generally uses two metal rods covered with rubber, which are fixed on the body horizontally and symmetrically. However, during the game, it often happens that the players fail to avoid the rotating rod when jumping and crush the rotating rod. Since the rotating rod is long, the torque at the connection with the body is large when it is compressed, which can easily damage the reliable connection between the rotating rod and the body. The product has poor reliability and short life. Moreover, the rotating rod is fixedly installed on the body. If it hits the players during rotation, it will cause pain and even injure the children's body, which makes it less safe to use. Summary of the invention

The characteristic of the present invention is that the rotating rod and the rotating shaft are connected to each other by an automatic return elastic universal joint, and the automatic return elastic universal joint includes a universal joint and a spring device. The spring device consists of a spring, a static spring seat, and a dynamic spring seat. Both ends of the spring are fixedly installed between the static spring seat and the dynamic spring seat. The center of the static spring seat is fixedly installed on a connecting rod in the radial direction of the rotating shaft. The rotating rod is fixedly connected to the center of the end face of the dynamic spring seat. The universal joint is composed of a spherical concave hole in the center of the end face of the connecting rod and a sphere at one end of the universal transmission rod, and the other end of the universal transmission rod is fixedly connected to the center of the plane of the dynamic spring seat.

[0005] Preferably, the automatic return elastic universal joint has an adjustment device, which adopts a screw portion set on the universal transmission rod, a center hole set in the plane of the dynamic spring seat, the screw portion of the universal transmission rod moves through the center hole in the plane of the dynamic spring seat, and a nut is installed on the screw of the universal transmission rod, and the end face of the nut is pressed and installed against the plane of the dynamic spring seat.

[0006] Preferably, a plurality of tension springs are arranged between the dynamic spring seat and the rotating frame, one end of the tension spring is connected to the upper edge of the dynamic spring seat center line, and the other end is connected to the rotating frame above the dynamic spring seat.

[0007] Preferably, the output shaft of the reducer is connected to the rotating shaft of the rotating frame by a flexible device, the flexible device includes at least two cylindrical springs, an upper flange, and a lower flange, the two ends of the cylindrical spring are respectively fixedly connected to the lower end surface of the upper flange and the upper end surface of the lower flange, the center of the upper end surface of the upper flange is fixedly connected to the rotating shaft, and the lower end surface of the lower flange is fixedly connected to the output shaft, and bolts are installed between the upper flange and the lower flange, the bolts pass through the center of the cylindrical spring, and are tightened and installed by adjusting nuts.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the rotating rod and the rotating shaft are connected to each other by an automatic return elastic universal joint. When the recreational personnel touch or press the rotating rod, the spring is compressed and deformed, and the rotating rod is tilted in the force direction along with the universal transmission rod. When the external force of the rotating rod disappears, the rotating rod automatically returns to its original position. During use, the rotating rod and the rotating frame are not easily crushed, and the recreational personnel will not be injured. The product is reliable in use, has a long service life, and is highly safe. BRIEF DESCRIPTION OF THE DRAWINGS
