[0006] A rotating jumping ball comprises an outer ring, a connecting rope and a sphere, one end of the connecting rope is fixedly connected to the outer wall of the outer ring, the other end of the connecting rope is fixedly connected to the sphere, an inner fixed ring is movably arranged on the inner side of the outer ring, an annular groove is provided on the inner side of the outer ring, and a plurality of universal balls distributed in an annular pattern are equidistantly arranged at the groove bottom corresponding to the annular groove, a plurality of connecting blocks extending into the annular groove and abutting against the outside of the universal balls are fixedly connected to the outer wall of the inner fixed ring, an elastic air bag is fixedly connected to the inner side of the inner fixed ring, the inner fixed ring is a hollow structure, and a plurality of ventilation holes connected to the elastic air bag are provided on the inner side, and an inflation nozzle is also fixedly connected to the surface of the inner fixed ring.

[0007] Preferably, an opening and closing valve is installed on the inflation nozzle.

[0008] Preferably, a side wall of the sphere is provided with a winding groove for winding a connecting rope, and an inner wall of the sphere corresponding to the winding groove is detachably connected to a U-shaped pressing plate pressed outside the connecting rope via bolts.

[0009] Preferably, a circle of flexible cushion is fixedly connected to the inner side of the elastic airbag.

[0010] Preferably, the outer wall of one end of the connecting block away from the inner fixed ring is configured as an arc surface matching the annular groove.

[0011] Preferably, the inner wall of the annular groove of the outer ring is arranged to fit with the outer wall of the connecting block.

[0012] Compared with the prior art, the present application provides a rotating bouncing ball, which has the following beneficial effects:

[0013] 1. The rotating jumping ball is provided with an outer ring, a connecting rope and a sphere. Before use, the inner fixed ring is set outside the ankle, and air is inflated into the inner fixed ring and the elastic airbag through an inflation nozzle. The elastic airbag swells and cooperates with the flexible cushion to be clamped outside the ankle to achieve relative fixation. During use, the inner fixed ring and the outer ring are connected by sliding through a connecting block and a universal ball through the outer ring and the connecting rope to drive the sphere to rotate, while the inner fixed ring does not move relative to the child's ankle, so no friction damage will occur, making it safer and more comfortable for children to use.

[0014] 2. The rotating jumping ball, through the sphere and the U-shaped pressing plate, can select the length of the connecting rope according to the playing needs, wind the excess connecting rope into the winding groove outside the sphere, and then use the bolts to press the U-shaped pressing plate onto the end of the connecting rope to fix the connecting rope. The length can be quickly adjusted according to the needs, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS
