DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments:

[0027] like Figures 1-6 As shown: A kettlebell, comprising a kettlebell body 1 with a handle 10 and a counterweight attachment 2, the lower end of the kettlebell body 1 is recessed inward to form an external threaded connection portion 11, the counterweight attachment 2 is a hemispherical structure, and has an accommodating space 3 inside, the inner side of the upper end of the counterweight attachment 2 is formed with an internal threaded connection portion 12 used in conjunction with the external threaded connection portion, the counterweight attachment 2 is connected to the lower end of the kettlebell body 1 through the internal threaded connection portion 12 and the external threaded connection portion 11, and the outer side of the counterweight attachment 2 close to the kettlebell body 1 is flush with the outer side of the kettlebell body 1 close to the internal threaded connection portion 12 , making the entire kettlebell look more rounded and not protruding. The counterweight attachment 2 includes a support part 21 and a flexible part 22. The flexible part 22 is coated on the outer peripheral surface of the support part 21. The utility model places sand in the counterweight attachment. The flexible part of the counterweight attachment is made of silicone or rubber material and is connected to the kettlebell body through the support part. The kettlebell body is made of hard plastic, which is convenient for users to grasp; the flexible part is to play a buffering role. Even if the kettlebell falls out of hand during use, the part in contact with the human body is basically the flexible part, which minimizes damage to the human body.

[0028] In the above-mentioned kettlebell, an abutment step 13 is provided between the lower end portion of the kettlebell body 1 and the external threaded connection portion 11, and the upper end faces of the support member 21 and the flexible member 22 abut against the abutment step 13 at the same time. The flexible member 22 is made of rubber or silicone material. Specifically, the upper end faces of the flexible member and the support member abut against the abutment step at the same time. The flexible member can increase the friction between the counterweight attachment and the abutment step, thereby avoiding the counterweight attachment from shaking during use and improving the connection stability between the counterweight attachment and the kettlebell body. The support member 21 and the flexible member 22 are a secondary overmolding structure (secondary overmolding is to first form the support member in mold one, and then place the support member in mold two for overmolding to form the counterweight attachment).

[0029] In the above-mentioned kettlebell, the outer surface of the support member 21 is formed with a supporting protrusion 211 protruding outward, and the flexible member 22 is provided with a supporting ring groove 212 used in conjunction with the supporting protrusion 211. Specifically, this is to increase the connection area between the support member and the flexible member, further improve the connection stability between the flexible member and the support member, and the designed supporting protrusion and support ring groove can play a good supporting role.

[0030] In the above-mentioned kettlebell, the lower end portion of the support member 21 extends downward and bends inward to form a support ring 213. The flexible member 22 is provided with a support step 214 that contacts the lower end surface of the support ring 213. Specifically, the designed support ring can support the flexible member to ensure that its external contour is not deformed.

[0031] In the above-mentioned kettlebell, the kettlebell body 1 has a second accommodating space 14, and a through hole 15 is provided at the lower end of the kettlebell body 1. The through hole 15 can connect the accommodating space 1 3 with the accommodating space 2 14. Specifically, the user can add sand to the accommodating space 2 through the through hole to increase the overall weight of the kettlebell.

[0032] In the above-mentioned kettlebell, the kettlebell body 1 is made of a PVC material as a whole. Specifically, this is to facilitate the molding of the kettlebell body.

[0033] In the above-mentioned kettlebell, the flexible member 22 is a hemispherical structure.

[0034] In the above-mentioned kettlebell, the length h of the external threaded connection portion 11 is shorter than the length of the support member 21. Specifically, this can ensure that the counterweight attachment can accommodate as much sand as possible when it is effectively connected to the kettlebell body.

[0035] In the above-mentioned kettlebell, the handle 10 is provided with a continuous arc groove 101. Specifically, this is to facilitate the user to grasp the kettlebell through the handle.

[0036] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
