By adopting the technical scheme, the spoke and the rotary ball can be firmly connected together to bear stronger force.

The method is further optimized as follows: the spoke is made of aluminum alloy.

By adopting the technical scheme, the spoke made of the aluminum alloy material is light in weight and convenient to carry.

The method is further optimized as follows: the central disk is made of stainless steel.

By adopting the technical scheme, the novel outdoor sports shoes are not easy to rust, can be used for outdoor sports for a long time, and are attractive.

The method is further optimized as follows: the surface of the wheel body is subjected to antiseptic treatment.

By adopting the technical scheme, the sports entertainment can be carried out even on rainy days or ponding roads, and better experience is brought to users.

1 and 2.

An eccentric wheel of a bicycle is used for dispersing the centripetal force generated when a wheel body 1 rotates and comprises the wheel body 1, an eccentric shaft 3 and a central shaft 4. The eccentric shaft 3 and the central shaft 4 are positioned inside the wheel body 1, the central shaft 4 is positioned at the central position of the wheel body 1, and the eccentric shaft 3 is positioned at the eccentric position of the wheel body 1. Also comprises a plurality of spokes 2, a plurality of rotating balls 6, a plurality of fixed shafts 7 and a central disc 8. The central disc 8 is located the central axis of wheel body 1, has seted up a plurality of mounting groove 5 on the inner wall of wheel body 1, and every changes partly being located mounting groove 5 of ball 6, is provided with first floating bead 50 between every ball 6 and the mounting groove 5. Another portion of each ball 6 is fixedly connected to one end of each spoke 2. The rotary ball 6 is connected with the first floating ball 50 in a floating way, and can buffer the acting force generated by the rotary ball on the wheel body 1.

As shown in fig. 2, each spoke 2 is composed of two arcs, and the two arcs are correspondingly connected end to end. Each fixed shaft 7 is respectively connected with the central disc 8, and a plurality of second floating beads 70 are arranged on the fixed shafts 7. A plurality of second floats pearl 70 and is located between every spoke 2 and every fixed axle 7, and the other end and the central disk 8 of spoke 2 are connected through a plurality of second floats pearl 70, and central disk 8 adopts stainless steel matter to make, and is difficult for rustting, can use for outdoor exercises for a long time, and is pleasing to the eye beautiful moreover. One end of the spoke 2 is fixedly connected with the inner wall of the rotating ball 6, so that the spoke 2 is directly integrated with the rotating ball 6, and the bearing capacity is stronger. The spoke 2 can also be an arc surface, and the spoke 2 with the arc surface can bear stronger centripetal force, so that the wheel body 2 can bear larger load and the applicability is strong.

One end of the spoke 2 is fixedly connected with the geometric center of the rotating ball 6, so that the spoke and the rotating ball 6 can be firmly connected together to bear stronger force. The spoke 2 is made of an aluminum alloy material, and the spoke 2 made of the aluminum alloy material is light in weight and convenient to carry.
