Among them, the rotating system is equipped with a spindle inside a rotating body, and the two ends of the spindle are respectively The pivot is provided with a bearing, and a rotating member extends vertically from the center of the spindle. The rotating member rotates radially centrifugally with the spindle as the axis, and the rotating member can be further provided with at least one counterweight, and The length of the rotating member combined with the counterweight is smaller than the radius of the rotating body; with the above structure, the user can operate the rotating body at any time and perform hand, wrist, or foot training, and when applying force When the rotating body is in the rotating body, the rotating member combined with the counterweight will rotate silently inside the rotating body. However, it has the following disadvantages:

(1) There is a T-shaped structure between the spindle and the rotating part, and the spindle rotates with its two ends as fulcrums. Therefore, when force is applied to the rotating body, the two fulcrums at the two ends of the spindle and The swing point of the counterweight forms a triangular point, and when applying force, the spindle, the rotating member and the counterweight need to be swung at the same time, which makes the rotation resistance of the spindle larger and makes it difficult for the user to start the swing and is not smooth.

(2) The two fulcrums at the two ends of the mandrel are located in two different shells respectively. Therefore, the assembly between the two shells needs to be very precise. Once the assembly is not accurate, the two ends of the mandrel and the two Duanzhi The bearings and the accommodating holes for accommodating the two bearings in the two housings will cause the assembly to be not on the same center line, causing the rotation of the spindle to become stuck and not smooth.

(3) Continuing from the explanation in (2) above, in order to achieve accurate assembly, manufacturers often have to assemble carefully and slowly, resulting in longer assembly time and higher assembly and labor costs.

(4) There are too many components and the assembly is cumbersome, and the assembly and labor costs increase, resulting in the overall product cost being too high, uncompetitive in the market, and difficult to sell.

In view of this, the inventor has many years of experience in the manufacturing, development and design of related products. After detailed design and careful evaluation based on the above goals, he finally arrived at a truly practical invention.

In view of the fact that the rotating body of the previous creation application has many rotation fulcrums and inaccurate assembly in its structural design, the two ends of the spindle, the bearings at the two ends of the spindle, and the two housings housing the two bearings are The assembly between the receiving holes is not on the same center line, causing the rotation of the mandrel to be stuck and not smooth. It is also difficult to assemble accurately, which lengthens the assembly time. In addition, there are too many components and the assembly is cumbersome, which in turn increases the height of the assembly. and labor costs.

The present invention provides a fitness ball structure with smooth swing, which includes: two shells, which together form a hollow sphere. Each of the two shells has a groove space formed on the inside, and a through hole is provided in the center of the bottom of the groove space. There are fixing holes inside and outside the casing, and a pivot seat is protruding from the bottom of the groove space toward the opening direction of the casing. A pivot post is protruded on the pivot seat, and a pivot post is passed through the center of the pivot post. through holes to the fixing holes; two supporting members are respectively provided to cover the two fixing holes of the housing and have inner and outer sides; a weight group is composed of at least one spindle, A rotating member and a counterweight body are combined with each other, in which the two ends of the spindle are respectively passed through the corresponding pivot seat holes, so that the two ends of the spindle are fixed on the respective pivot seats. On the through hole, a set of holes is formed on one end of the rotating member, and at least one bearing is provided on the inner diameter of the sleeve. The rotating member is radially sleeved on the center of the spindle through the sleeve, and the rotating member is different from the sleeve. It is assumed that one end of the mandrel is connected to the counterweight body, and the counterweight body further includes at least one weighting block. The weighting block is detachably combined with the counterweight body, so that the rotating member and the counterweight body are connected to each other. The mandrel is an axis that rotates radially and centrifugally in the hollow sphere; the two handrail protectors are respectively arranged on the corresponding two sides of the hollow sphere and close to the two support members.

The effect of the present invention is that: the number of overall components is greatly reduced, which reduces assembly and parts costs; and when force is applied to the fitness ball, it remains silent during use and will not disturb other people; and, the fitness ball is centrifugal.
