By adding fluid (such as water, liquid or sand) into the accommodating chamber 400 for counterweighting, and because the fluid has fluidity when filled into the accommodating chamber 400, it can be ensured that the lower shell 300 retains its good buffering and shock absorbing performance when it contacts an object.
[0036] Optionally, the handle 200 is rigidly connected to the upper shell 100 and is not easily damaged.
[0037] Optionally, the handle 200 and the upper shell 100 are integrally formed, making the connection between the two more stable and facilitating rapid production and manufacturing.
[0038] Optionally, the handle 200 includes a first handle shell 210 and a second handle shell 220, and the first handle shell 210 and the second handle shell 220 are connected to each other; dividing the handle 200 into the first handle shell 210 and the second handle shell 220 facilitates the separate production and manufacturing of the two, and also facilitates the connection and assembly between the two.
[0039] In an optional embodiment, a sealing ring 500 is connected to the outer side of the connection between the upper shell 100 and the lower shell 300 , and the sealing ring 500 connects the upper shell 100 and the lower shell 300 at the same time.
[0040] In this embodiment, since the fluid is stored in the accommodating cavity 400, in order to prevent fluid leakage and to strengthen the connection between the upper shell 100 and the lower shell 300, a sealing ring 500 is connected to the outside of the connection between the upper shell 100 and the lower shell 300 to solve the above technical problems.
[0041] In an optional embodiment, the upper shell 100 and the lower shell 300 are connected by hot melt to ensure good sealing stability after the upper shell 100 and the lower shell 300 are connected.
[0042] In an optional embodiment, the upper shell 100 and the lower shell 300 are glued together.
[0043] In an optional embodiment, the sealing ring 500 is connected to the upper shell 100 and the lower shell 300 by hot melt, which further ensures the stability of the sealing connection between the upper shell 100 and the lower shell 300.

[0047] In an optional embodiment, the upper shell 100 and the lower shell 300 are both hemispherical, and the volume ratio between the upper shell 100 and the lower shell 300 is 0.9-1.1:0.9-1.1, so that the volumes of the upper shell 100 and the lower shell 300 are similar, which can facilitate demolding from the perspective of mold technology; preferably, the volume ratio between the upper shell 100 and the lower shell 300 is 1:1.
[0048] In an optional embodiment, an injection module 600 is provided on the upper shell 100 to communicate with the accommodating chamber 400 , so that liquid can be injected into the accommodating chamber 400 through the injection module 600 when needed.
[0049] In an optional embodiment, the injection module 600 includes a countersunk through hole 610 opened in the upper shell 100, and a plug 620 is installed in the countersunk through hole 610, and the upper surface of the plug 620 is sunken or flush with the countersunk through hole 610.
[0050] In this embodiment, the countersunk through hole 610 allows the plug 620 to be embedded in the upper shell 100 without protruding from the outer surface of the upper shell 100, thereby making the appearance of the kettlebell more beautiful and the plug 620 less likely to be damaged; preferably, the plug 620 is made of a deformable elastic material to ensure a good seal when the plug 620 plugs the countersunk through hole 610.
