[0002] Kettlebells are a common piece of fitness equipment used in strength training. They're typically swung and held with both hands, training multiple muscle groups and promoting healthy, coordinated development across the body. Traditional kettlebells are molded in one piece, with fixed weights. To accommodate varying training intensities and requirements, a set of kettlebells with varying weights is often purchased. These are more suitable for use in fitness studios than for home use.

[0003] To overcome the problems of fixed, non-adjustable weights and the need to purchase a complete set of kettlebells, Chinese Patent Publication No. CN217246498U discloses a weight-adjustable kettlebell. This structure allows kettlebells of varying weights to be obtained simply by adjusting the number of internal counterweights by inserting a pin into different positions. A single kettlebell can replace a traditional set of kettlebells, making it more economical and convenient for use in fitness centers and at home, and taking up less space. This effectively solves the aforementioned problems with traditional kettlebells. However, this structure has the following shortcomings during use: First, each counterweight requires a limit assembly to be installed in conjunction with the pin, making the counterweight structure overly complex, inconvenient to manufacture and install, and subject to the risk of the limit assembly failing. Second, because the counterweights lack a base, they are easily misaligned during use, making it impossible to neatly arrange them. Third, the gaps between the counterweights are large, resulting in mechanical collision noises during training. Further improvements are needed.

The weight plates 3 are provided with arc-shaped hanging blocks 11 corresponding to the hanging blocks 21. The arc-shaped hanging blocks on the weight plates 3 are arranged in an arc-shaped manner. The blocks 11 are arranged from long to short from top to bottom and form counterweight adjustment gears, with one block for each. There are a total of six counterweight plates 3 and a neutral block, each weighing 3 kg, and a total of seven counterweight adjustment gears. The base 7 is provided with a base positioning groove 36, through which the center positioning seat 5 is mounted on the base 7, ensuring that the center positioning seat 5 is installed in a unique position. A turntable 6 is provided between the base 7 and the center positioning seat 5, and the center positioning seat 5 is located at the center of the turntable 6. The turntable 6 is rotatably arranged on the base 7 via a ball rotating frame 31. The counterweight plates 3 are positioned on the center positioning seat 5, and the housing is positioned on the turntable 6 and covers the counterweight plates 3. When the handle 1 drives the housing to rotate, the hanger 21 on the counterweight support frame 20 slides under the arc-shaped block 11 corresponding to the counterweight plate 3 to achieve counterweight adjustment.

[0026] In order to ensure stable and reliable weight adjustment and prevent the weight plate 3 from rotating, a rotation locking device 19 of the weight plate is provided in the housing. The rotation locking device 19 includes a guide rod 22 slidingly arranged on the housing, a weight plate locking block 25 fixedly connected to the top of the guide rod 22, and a locking block spring 24 that applies elastic force to the weight plate locking block 25. The topmost weight plate 3 is provided with an anti-rotation positioning groove 10 that cooperates with the weight plate locking block 25. The number of the anti-rotation positioning grooves 10 is consistent with the weight adjustment gear. , there are 7 anti-rotation positioning grooves 10 in total; when the shell is placed on the turntable 6, the guide rod 22 is pressed against the turntable 6, and the counterweight plate locking block 25 moves upward under the action of the guide rod 22, and the counterweight plate locking block 25 is separated from the corresponding anti-rotation positioning groove 10 and unlocked, and the shell can be rotated relative to the counterweight plate 3 to adjust the weight; when the handle 1 is lifted, the guide rod 22 is disengaged from the turntable 6, and the counterweight plate locking block 25 is combined with the corresponding anti-rotation positioning groove 10 and locked under the action of the locking block spring 24, and the counterweight plate 3 cannot rotate relative to the shell.

[0027] In order to achieve gear adjustment and prevent gear adjustment from being disordered, a bottom cover 30 is fixed on the turntable 6, and a turntable gear locking device 14 is provided between the turntable 6 and the bottom cover 30.

When the handle 1 is lifted and the housing is separated from the straight pin portion 35, the lock pin 28 bounces upward under the elastic force of the lock pin spring 29, and the locking portion 38 cooperates with the locking groove 34 to make the shift lock plate 26 immovable, and the lock head 37 cooperates with the shift slot 39 to lock the turntable 6, thereby ensuring that the gear adjustment is not blocked.

[0028] In order to ensure that the counterweight plates 3 are stacked smoothly, a center positioning piece 18 is fixed on the counterweight support frame 20, a center positioning groove 9 is provided on the upper part of the counterweight plate 3, a counterweight plate positioning block is provided on the bottom, and a counterweight plate positioning groove 12 is provided on the center positioning seat 5. The center positioning piece 18 on the counterweight support frame 20 is rotatably matched with the center positioning groove 9 of the uppermost counterweight plate 3, and the counterweight plate positioning block of the lowermost counterweight plate 3 is positioned and matched with the counterweight plate positioning groove 12 on the center positioning seat 5. The counterweight plates 3 are positioned by the counterweight plate positioning block and the center positioning groove 9. The matching angles of each piece of the counterweight plate positioning block and the center positioning groove 9 of the counterweight plate 3 are different. They can only be stacked in the order of arrangement, and cannot be stacked if they are not in the order of arrangement.

[0029] To ensure the proper placement of the housing and turntable 6, the turntable 6 is provided with a housing positioning seat 8. The housing is also provided with a positioning guide 23 that cooperates with the housing positioning seat 8. The housing can only be inserted in one position, ensuring accurate positioning of the housing and turntable 6. The center positioning seat 5 is provided with an initial position arrow 13 and a positioning arrow. The weight stack 3 is provided with a weight stack positioning arrow and a number 4 that cooperates with the positioning arrow on the center positioning seat 5. The numbers on the weight stack 3 are arranged sequentially from top to bottom.

[0030] To facilitate intuitive reading of the counterweight, the base 7 is provided with a counterweight indicator window 16 aligned with the counterweight adjustment position, and the turntable 6 is provided with an indicator arrow 15 that cooperates with the counterweight indicator window 16 to indicate the counterweight. A counterweight scale 32 and a transparent cover 33 are mounted on the counterweight indicator window 16 to cover the counterweight scale 32.

[0031] The invention works as follows: in the initial state, the initial position arrow 13 on the center positioning seat 5 and the indicator arrow 15 indicating the counterweight on the rotating disk 6 are aligned with the counterweight indicator window 16, the counterweight plates 3 stacked together in the order of arrangement are placed on the center positioning seat 5, the counterweight plate positioning arrow and the number 4 are aligned with the positioning arrow on the center positioning seat 5, the housing is placed on the rotating disk 6 through the positioning guide 23 and the housing positioning seat 8, as shown in Figures 1 and 8, the counterweight is adjusted to the neutral position, all the hanging parts 21 do not cooperate with the corresponding arc-shaped gear 11, the indicator arrow 15 indicating the counterweight is aligned with the counterweight indicator window 1 for the neutral counterweight of 2kg, that is, the weight of the handle 1 and the housing. At this time, the guide rod 22 is pressed against the rotating disk 6, and the guide rod 22 drives the counterweight plate locking block 2 to move upward after overcoming the elastic force of the locking block spring 24, and the counterweight plate locking block 25 is separated from the anti-rotation positioning groove 10 of the neutral position, and the rotation locking device 19 is in the unlocked state, and the housing can rotate relative to the counterweight plate 3 to adjust the counterweight. At the same time, the shell presses on the straight pin portion 35 of the lock pin 28, and the lock pin 28 moves downward after overcoming the elastic force of the lock pin spring 29. The locking portion 38 disengages from the locking groove 34, and the straight pin portion 35 cooperates with the locking groove 34. The locking portion 38 is misaligned with the locking groove 34, and the turntable gear locking device 14 is in an unlocked state. The lock head 37 of the gear lock plate 26 cooperates with the neutral gear slot 39. When the turntable 6 is rotated, the gear lock plate 26 overcomes the elastic force of the lock plate spring 27 and can move outward relative to the straight pin portion 35 to realize gear adjustment.

[0032] The kettlebell weight is adjusted as follows: when the handle 1 is rotated by one gear, the handle 1 drives the hanger 21 on the counterweight support frame 20 to rotate through the housing, and the hanger 21 of the first gear slides into the arc-shaped gear 11 under the counterweight plate 3 of the first gear to achieve counterweight adjustment. The hangers 21 of other gears are still in a separated state from the arc-shaped gear 11 of other gears. At this time, the indicator arrow 15 indicating the counterweight is aligned with the counterweight indicator window 1 of the first gear with a counterweight weight of 5kg, the counterweight plate locking block 25 corresponds to the anti-rotation positioning groove 10 of the first gear, and the lock head 37 of the gear locking plate 26 slides from the gear notch 39 of the neutral gear into the gear notch 39 of the first gear; continue to rotate the handle 1 according to the above steps to achieve counterweight adjustment from the second gear to the sixth gear, which will not be repeated here. Figure 9 shows that the counterweight adjustment is in the sixth gear position, all hangers 21 are matched with the corresponding arc-shaped gear 11, and the indicator arrow 15 indicating the counterweight is aligned with the counterweight indicator window 1 of the sixth gear with a counterweight weight of 20kg.

[0033] After the kettlebell's weight adjustment is complete, when the handle 1 is lifted, the guide rod 22 separates from the turntable 6. The weight plate lock block 25, under the elastic force of the lock block spring 24, automatically engages with the corresponding anti-rotation positioning groove 10 to lock the weight plate 3, preventing the weight plate 3 from rotating relative to the housing, thereby ensuring a secure connection between the weight plate 3 and the housing during training. Simultaneously, the housing separates from the base 7, and the lock pin 28 springs upward under the elastic force of the lock pin spring 29. The locking portion 38 cooperates with the locking groove 34 to prevent the shift lock plate 26 from moving. The lock head 37 of the shift lock plate 26 locks into the shift notch 39 of the center positioning seat 5 corresponding to the gear position, thereby locking the turntable 6 and ensuring that the gear indication is consistent with the weight adjustment.

[0034] The above is only a specific embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention shall fall within the scope of protection of the present invention.
