[0002] The kettlebell is a traditional fitness tool originating in Russia. Shaped like a cannonball with a handle, it is typically made of cast iron or cast steel. It offers unique advantages, enabling functional training, mimicking everyday movements, and enhancing the body's athletic ability in daily life. Training with kettlebells works multiple muscle groups throughout the body, including the legs, glutes, and arms. Furthermore, kettlebell training improves cardiovascular function. Common exercises include kettlebell swings and deadlifts. When using kettlebells, it is important to warm up properly, maintain correct posture, and choose an appropriate weight to prevent injury. Kettlebells are popular because they effectively and comprehensively improve overall explosive power.

[0003] For example, Chinese Patent Publication No. CN219208874U describes a kettlebell comprising multiple stackable and connected bell pieces. A handle is fixedly connected to the top bell piece. A limiting ring is fixed to the upper surface of each bell piece, and a limiting groove is formed on the lower surface. An outer hole communicating with the limiting groove is formed on the side of each bell piece, and an internal threaded hole is formed on the limiting ring. The limiting ring of each bell piece engages with the limiting groove of the bell piece above it, and the bell piece can rotate to a position where its outer hole is coaxially opposite to the internal threaded hole of the bell piece above it. A bolt is threaded into the internal threaded hole, and the end of the bolt can pass through the outer hole of a bell piece and be threadedly connected to the internal threaded hole of the bell piece below it. Each bell piece has a coaxially penetrating insertion hole in its center. The kettlebell also includes a kettlebell base, which includes at least a base and a rod fixedly connected to the center of the upper surface of the base, with the rod passing through the insertion hole. The bell pieces are inserted into the kettlebell base. However, in actual use, the following shortcomings still exist:

[0004] The aforementioned device connects the various bell pieces via insert rods, thereby adjusting the weight of the kettlebell. However, in actual use, it requires frequent tightening of bolts, making the operation cumbersome and inconvenient. Furthermore, as the number of bell pieces increases, the overall shape and structure of the kettlebell become larger, requiring more space to place it. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 , Figure 2 and Figure 7As shown, this utility model provides a stackable kettlebell, including a kettlebell body 1 and a kettlebell handle 11 fixedly connected to the top of the kettlebell body 1. The kettlebell body 1 has a semi-ellipsoidal cavity structure and a flat bottom structure, which prevents the kettlebell from tipping over when placed on the ground. The kettlebell handle 11 has a semi-ellipsoidal cavity structure of one-tenth of its original size. The kettlebell body 1 and the kettlebell handle 11 have a smooth transition, making the overall appearance of the kettlebell an ellipsoidal structure with a notch, which is more aesthetically pleasing. The opening angle between the kettlebell body 1 and the kettlebell handle 11 is 60-80 degrees, which allows the stacking blocks 2 to be easily inserted or removed. The kettlebell body 1 contains... The bottom of the cavity is fixedly connected to the bottom of the support column 3. The support column 3 is an elliptical column. Multiple stacking blocks 2 are stacked inside the kettlebell body 1. Each stacking block 2 is a semi-ellipsoidal cavity structure but of different sizes. Smaller stacking blocks 2 can be stacked on top of slightly larger stacking blocks 2. Each stacking block 2 has an elliptical fixing hole 21 at its bottom. The inner side of the fixing hole 21 is movably connected to the surface of the support column 3 so that each stacking block 2 can be movably inserted into the support column 3. Multiple slots 31 are provided on the support column 3. The support column 3 is connected to a fixing mechanism 4 through the slots 31 to fix each stacking block 2 to the inner cavity of the kettlebell body 1.

[0028] like Figures 3-6As shown, the fixing mechanism 4 includes a fixing seat 41 sleeved on the surface of the support column 3. A groove 415 is provided inside the fixing seat 41, and a slider 413 is slidably disposed within the groove 415. The slider 413 is generally convex in shape. The middle part of the slider 413, near the support column 3, penetrates the inner wall of the groove 415 to the slot 31. The protruding part of the slider 413 engages with the inner wall of the slot 31, enabling the fixing seat 41 to be engaged with the support column 3. A limit spring 412 is fixedly disposed on the side of the slider 413 away from the slot 31. The other end of the limit spring 412 is fixedly connected to the inner wall of the groove 415 away from the slot 31. The limit spring 412 can firmly hold the slider 413 against the slot 31, thus achieving fixation. Two buttons 411 are symmetrically distributed on both sides of the fixing seat 41. Both buttons 411 are slidably connected to the inner wall of the groove 415. The two sliders 413 are close to... Two wedge blocks 414 are fixedly installed at both ends of one side of the slot 31. The inner ends of the two buttons 411 abut against the inclined surfaces of the wedge blocks 414. The buttons 411 can drive the wedge blocks 414 and the slider 413 to move. Two symmetrically distributed limit rods 416 are fixedly installed at the bottom of the fixed base 41. The bottom of the fixed base 41 is fixedly connected to the upper end of the support spring 42. The lower end of the support spring 42 is fixedly connected to the top surface of the support block 43. Two symmetrically distributed limit holes 431 are opened at the bottom of the support block 43. The limit rods 416 are movably engaged with the limit holes 431. An elliptical through groove 433 is opened in the middle of the support block 43. The through groove 433 is slidably connected to the surface of the support column 3, so that the support block 43 and the fixed base 41 will not shift when moving up and down on the surface of the support column 3. A silicone pad 432 is fixedly installed at the bottom of the support block 43, which can abut against the inner side of the stacked block 2 more stably.

[0029] The principle and process of this utility model:

[0030] When using this device, first place the kettlebell body 1 bottom-down on a flat surface. Press and hold the buttons 411 on both sides of the fixing base 41. When the buttons 411 move inward, they will cause the wedge block 414 to move towards the limiting spring 412, simultaneously causing the slider 413 to move out of the slot 31 and no longer provide a limiting effect on the fixing base 41. Pull the fixing base 41 upward so that the support block 43 is completely separated from the support column 3. Then, stack the stacking blocks 2 of different sizes on the inner support column 3 in descending order of size to adjust the overall weight of the kettlebell to a suitable state. Finally, press and hold the two buttons 411 to fix the mechanism. 4. Insert the support block 43 downward and the fixing seat 41 upward back onto the support column 3, so that the silicone pad 432 at the bottom of the support block 43 abuts against the inner side of the stacked block 2. The fixing seat 41 continues to move downward, and the limiting rod 416 is inserted deeper into the limiting hole 431. The support spring 42 is gradually compressed. Release the button 411, and the slider 413 is pushed into the slot 31 under the elastic force of the limiting spring 412. When the slider 413 is inserted into the slot 31, the support spring 42 is in a highly compressed state, which can firmly fix the stacked block 2 into the inner cavity of the kettlebell body 1 for subsequent exercise.
