[0024] The kettlebell of the utility model is as follows Figure 1-2 The structure shown includes a kettle body 1 and a kettle lid 2 and a ring 3 located therebetween. The kettlebell structure of this embodiment is simple and reasonably designed. Based on the kettlebell structure of this embodiment, the ring 3 can be first fixed to the kettle body 1 or the kettle lid 2 during production. Generally, the ring 3 is injection-molded and fixed to the kettle body 1 for the convenience of demoulding. The ring 3 produced in this way has no gap with the kettle body 1, which can improve the sealing and connection strength. Subsequently, the kettle body 1 with the ring 3 is fitted with the injection-molded kettle lid 2, and the notch 6 and the fitting edge 7 are correspondingly connected. On this basis, a sealing metal ring 8 is provided at the bottom of the notch 6 and then fitted relative to the fitting edge 7. Subsequently, the sealing metal ring 8 is heated by the eddy current effect to melt the contact part of the kettlebell. The melted and then cooled kettle lid 2 and the ring 3 can produce a hot-melt bonding effect, as shown in FIG. Figure 4 As shown, the kettle body 1, the kettle lid 2 and the ring 3 have stronger connection strength and sealing. On this basis, the structure of the ring 3 can be further improved. For example, a stepped chamfer can be set for the portion where the ring 3 is connected to the kettle body 1 to increase the friction area of ​​the connection with the kettle body 1 and improve the connection strength. The further setting of the sealing metal ring 8 also improves the strength of the kettlebell in the horizontal direction, reduces the deformation problem caused by horizontal collision at the edge of the kettle body where the kettlebell is most likely to collide during use and placement.
