DETAILED DESCRIPTION

[0027] The present application will now be further described in detail with reference to the accompanying drawings.

[0028] Please refer to Figures 1-4 shown, in this embodiment, a fitness ball is provided, including a hemispherical upper shell 1 and lower shell 2, the plane of the two is firmly connected to the bottom plate 3 by screw, to ensure the stability of the overall structure. The bottom plate 3 is provided with a rotating connection of the counterweight structure at the center, which is located in the cavity inside the shell, using the principle of inertia rotation, to realize the efficient training of the user's arm and wrist strength when swinging the fitness ball;

[0029] The plane part of the upper shell 1 and the lower shell 2 is provided with a notch 4, and the notch 4 is provided with a rotating connection of the traction hanging rope 5, so that the fitness ball can be connected with elastic rope or other fitness accessories through the traction hanging rope 5, further expanding its training function, providing additional strength load for the user, adapting to the diversified training needs;

[0030] The outer edge of the bottom plate 3 is designed as a ring-shaped arrangement of convex buckles 6 and concave buckles 7, which are adapted in shape to realize the quick clamping and separation of the upper shell 1 and the lower shell 2. This design not only makes the fitness ball have high structural stability in use, but also facilitates the user to quickly switch the training mode according to different training scenes, such as separating the two hemispheres for separate use or combining them into a whole for use, improving the flexibility and multifunctionality of the equipment;

[0031] The arc-shaped parts of the upper shell 1 and the lower shell 2 are provided with ergonomic handgrips 8, which are designed to facilitate stable gripping by the user during training, thereby improving the comfort and safety of inertial motion training.

[0032] The fitness ball combines inertial rotation training and multi-functional expansion. It can not only exercise arm and wrist strength through the rotation of the built-in weight structure, but also connect the traction rope 5 through the slots 4 on the upper and lower shell 2 planes to realize combined training with external accessories such as elastic ropes, providing additional strength load. The convex buckle 6 and the concave buckle 7 on the bottom plate 3 allow the upper and lower shells 2 to be quickly assembled and disassembled, thereby switching between different training modes. In addition, the arc-shaped handgrip 8 design not only facilitates user gripping, but also improves comfort and stability during training, significantly enhancing the practicality and user experience of the fitness ball, solving the problem of single function and limited use scenarios of existing equipment.

[0033] In this embodiment, the weight structure includes a connecting column fixedly connected to the shaft center above the bottom plate 3, and a connecting frame 9 rotatably connected to the connecting column through a bearing on the side of the connecting column. A weight block 10 is fixedly connected to one side of the connecting frame 9. The weight block 10 rotates around the connecting column under the action of inertia to enhance the strength load during training.

[0034] In this embodiment, the concave buckle 7 is accurately adapted to the shape of the convex buckle 6, and the two achieve efficient connection through rigorous geometric design. The convex buckle 6 and the concave buckle 7 not only match each other in shape, but also have uniform grooves 11 on the opposite sides for docking. These grooves 11 can be embedded in each other when clamped, further improving the firmness and stability of the connection. This design allows the upper shell 1 and the lower shell 2 to be quickly and accurately aligned during assembly, and through the double locking mechanism of the buckle and the groove 11, it ensures that the fitness ball will not loosen or come off during use due to intense exercise.

[0035] In this embodiment, one side of the slot 4 is designed with a straight slot 12 that penetrates the outer periphery of the shell. The structure of the straight slot 12 allows the traction rope 5 to be stably embedded and smoothly slide therein, ensuring that the traction force can be fully transmitted during various training processes. The straight slot 12 penetrates to the outer periphery of the shell, which not only facilitates the placement and adjustment of the traction rope 5, but also effectively prevents the rope 5 from falling off or being unevenly stressed during exercise, improving the safety and reliability of the overall training. One end of the traction rope 5 is connected with a hook, which can easily connect with elastic ropes, resistance bands or other fitness accessories, further expanding the functionality of the fitness ball. Users can quickly replace training accessories through the hook to seamlessly switch from inertial strength training to elastic resistance training. The combination of the straight slot 12 and the hook not only improves the flexibility of the equipment, but also allows the fitness ball to adapt to a wider range of training needs

[0036] The hand grip 8 is provided with an electronic display screen on one side, and a holding space is formed between the hand grip 8 and the shell.
