[0023] Next, the present utility model will be further described in conjunction with the accompanying drawings.

[0024] As Figures 1-5 shown, a weight-adjustable kettlebell includes a kettlebell body 1, a fixing rod 3, a plurality of counterweight blocks 4, a barbell buckle 5, and a kettlebell handle assembly 6.

[0025] Specifically, an installation groove 2 is provided in the kettlebell body 1, a fixing rod 3 is provided in the installation groove 2, and a plurality of counterweight blocks 4 are sleeved on the fixing rod 3. By adding or removing different numbers of counterweight blocks 4, the weight of the device can be changed to meet the different needs of users; a barbell buckle 5 (the barbell buckle 5 is an existing product, and the product number is LS3049) is closely attached to the fixing rod 3, and a plurality of counterweight blocks 4 can be stably fixed on the fixing rod 3 through the barbell buckle 5, effectively preventing the counterweight blocks 4 from shaking or moving during the use of the device; the kettlebell handle assembly 6 is detachably connected to the kettlebell body 1.

[0026] Specifically, the kettlebell handle assembly 6 includes a handle 61, a first threaded rod 62, a fixing block 63, and a kettlebell lid 64. The first threaded rod 62 is connected to the fixing rod 3, and the fixing block 63 is threadedly connected to the first threaded rod 62. The kettlebell lid 64 is fixed to the kettlebell body 1 by tightening the fixing block 63. The fixing block 63 is closely attached to the kettlebell lid 64, the kettlebell lid 64 is closely attached to the kettlebell body 1, and the handle 61 is connected to the kettlebell lid 64.

[0027] Specifically, a placement groove 8 is mirror - opened in the installation groove 2. The placement groove 8 facilitates the taking and placing of the counterweight 4. At the same time, the support plate 9 can move within the placement groove 8. The support plate 9 is closely attached to the inner wall of the placement groove 8. Two second threaded rods 10 are connected to the support plate 9. Two installation through - grooves 12 are mirror - opened on both the kettlebell body 1 and the kettlebell cover 64. Each second threaded rod 10 passes through the corresponding installation through - groove 12. Each second threaded rod 10 is threadedly connected with a fixing nut 13. The fixing nut 13 is located within the installation through - groove 12. The second threaded rod 10 located below the support plate 9 is longer than the second threaded rod 10 located above. A first gasket is closely attached between the fixing nut 13 and the installation through - groove 12. By threadedly connecting multiple fixing nuts 13 to the corresponding second threaded rods 10, the function of assisting in fixing the kettlebell cover 64 and the kettlebell body 1 is achieved.

[0028] Specifically, a through - hole 7 is opened on the kettlebell cover 64, and the first threaded rod 62 passes through the through - hole 7; the lower surface of the fixing block 63 is closely attached to a second gasket. A cutting layer is provided on the upper surface of the kettlebell cover 64. The cutting layer can ensure that there is sufficient contact area between the fixing block 63 and the kettlebell cover 64. The second gasket is closely attached to the cutting layer. The second gasket can increase the friction force between the fixing block 63 and the cutting layer, improving the stability of the fixing block 63.

[0029] Specifically, the counterweight 4 is a hollow circular disc - shaped structure and is made of cast iron material; the handle 61 is provided with first anti - slip patterns, which can increase the friction force between the exerciser's palm and the handle 61, facilitating various exercise movements; the fixing block 63 is evenly provided with second anti - slip patterns, which is convenient for rotating the fixing block 63, so that the kettlebell cover 64 and the kettlebell body 1 are closely attached or separated.

[0030] Working principle: When it is necessary to increase or decrease the counterweight of the kettlebell body 1, first disassemble multiple fixing nuts 13 from the corresponding second threaded rods 10 in sequence, and then push the second threaded rod 10 located below the support plate 9 until the second threaded rod 10 located above the support plate 9 disengages from the corresponding installation through - groove 12. At this time, the second threaded rod 10 located below the support plate 9 still passes through its corresponding installation through - groove 12. Then take out the fixing block 63, and the kettlebell cover 64 can be separated from the kettlebell body 1. Then remove the barbell buckle 5 to replace the counterweight 4. Then reverse the above steps to assemble the device.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
