Luminous jumping ball

Abstract

A luminous jumping ball includes a connecting rod, an ankle ring, and a roller. The ankle ring is fixedly connected to an end of the connecting rod, another end of the connecting rod facing away from the ankle ring is rotatably connected to a rotatable sleeve, the rotatable sleeve is fixedly connected to the roller through a spring, two ends of the spring are fixedly connected to an end of the rotatable sleeve and an end of the roller, respectively, and the spring, the rotatable sleeve, and the roller are coaxially arranged. The connecting rod and the roller are connected through the spring. When the roller collides with the ground, the spring acts as a cushion to prevent damage caused by rigid connection during the collision, thereby increasing a service life of the jumping ball and a smoothness of rotation of the roller.
