Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, specifically to a kettlebell that is easy to disassemble and has adjustable weight. Background Technology

[0002] Fitness equipment is generally categorized into two main types based on the number of training functions: single-function and multi-functional. Kettlebells are typically made of cast iron and come in various weights, including 10 kg, 15 kg, 20 kg, 25 kg, 30 kg, and 50 kg. In my country, there are also stone locks that resemble locks and are used in a similar manner to kettlebells. Kettlebells can be used for various pushing, lifting, raising, throwing, and squatting jumps. The difference between kettlebell training and dumbbell or barbell training is that kettlebells are more effective at comprehensively improving overall explosive power; therefore, kettlebells and stone locks have long been favored by fighters and martial artists.

[0003] However, existing designs have shortcomings such as not adequately meeting people's usage needs. An existing patent (publication number: CN203329271U) discloses a kettlebell including a handle and a counterweight ball. The handle is U-shaped, with its two open ends embedded inside the ball and fixedly connected to the counterweight ball. The bottom of the counterweight ball is flat. The distance between the two side walls of the handle gradually decreases from the closed end to the open end. An anti-detachment device is provided at the open end of the handle, and this anti-detachment device is fixedly connected to the open end of the handle. The beneficial effects of this utility model are: due to the structure where the distance between the two side walls of the handle gradually decreases from the closed section to the open end, and the anti-detachment device at the open end of the handle, the handle is less likely to fall off during prolonged use, reducing safety hazards. In the process of realizing this utility model, the inventor discovered the following problems with the existing technology: 1. Existing kettlebells are inconvenient to disassemble during use, and are usually too large to carry and move; 2. Existing kettlebells are usually too heavy or too light because they cannot be disassembled, and cannot be adjusted in weight, making them unsuitable for use by people in various fields. They also have limited functions and are prone to damaging the floor. Summary of the Invention

[0014] Optionally, the baffle and the load-bearing column form an integral structure, and the load-bearing column forms a snap-fit ​​structure with the baffle and the fixing slot.

[0015] This invention provides a kettlebell that is easy to disassemble and has adjustable weight, and has the following advantages:

[0016] 1. This easy-to-disassemble, weight-adjustable kettlebell has a threaded structure formed by a lead screw and a load-bearing column. Users can lift the entire kettlebell for exercise by using the lifting ring located on the top of the fixed block. The first, second, and third counterweight plates are respectively fitted onto the load-bearing column. Users can change the number of load-bearing plates to better suit different users.

[0017] 2. This easy-to-disassemble, weight-adjustable kettlebell can be rotatably connected to the first and second retaining rings via the first pivot. This allows the two retaining rings to be securely fitted onto the top of the load-bearing column. The pin and the latch are engaged, and turning the latch engages the pin, preventing the two retaining rings from loosening and facilitating the disassembly of the kettlebell. Securing the two retaining rings onto the top of the load-bearing column also prevents the bottom counterweight from swaying back and forth and facilitates the stacking and reduction of the counterweight.

[0018] 3. This easy-to-disassemble, weight-adjustable kettlebell features an internal spring in the base. When not in use, the kettlebell can be stored inside the base, and the spring's cushioning reduces damage to the base and extends its lifespan. A horizontal slot is fixed to the top of the base, allowing the support column to be placed horizontally on top of the base and engaged with the slot when the dumbbell is not in use. This prevents damage to the ground and also makes it easier for the user to grip.

[0019] 4. This easy-to-disassemble, weight-adjustable kettlebell is made by threading the second threaded post to the load-bearing post, and then attaching a counterweight plate to the outside of the first threaded post. The counterweight plate can be fixed by a limiting ring to prevent it from shaking, and the kettlebell can be converted into a dumbbell shape.

[0020] 5. This easy-to-disassemble, weight-adjustable kettlebell has baffles at both ends of the support column to prevent the counterweights on both sides from moving towards the middle when in dumbbell form, thus avoiding accidental injury to the user. When the kettlebell is not in use, the baffle at the bottom can be engaged with the fixing slot at the top of the support plate to prevent it from being unstable. Attached Figure Description

[0032] Please see Figures 1 to 7 This invention provides a technical solution: a kettlebell that is easy to disassemble and has adjustable weight, comprising a support column 1, a lead screw 2 threadedly connected to the top of the support column 1, a fixing block 3 fixedly connected to the top of the lead screw 2, lifting rings 4 fixedly connected to the upper sides of the fixing block 3, a first counterweight 5 sleeved on the bottom of the outer wall of the support column 1, a second counterweight 6 and a third counterweight 7 respectively sleeved at the axis of the outer wall of the support column 1, with the third counterweight 7 located on top of the second counterweight 6, a first retaining ring 8 and a second retaining ring 9 respectively sleeved on the top of the outer wall of the support column 1, with the second retaining ring 9 located on one side of the first retaining ring 8, a lever 10 and a third rotating shaft 14 rotatably connected to one end of the first retaining ring 8, with the lever 10 located at the axis of the third rotating shaft 14, and a first rotating shaft 12 rotatably connected to the other end of the first retaining ring 8, and the second retaining ring 9... One end is rotatably connected to a pin 11 and a second rotating shaft 13, with the pin 11 located at the axis of the second rotating shaft 13. Both ends of the load-bearing column 1 are fixedly connected to baffles 15. Both ends of the load-bearing column 1 are fixedly connected to threaded grooves 16. The inner walls of both ends of the load-bearing column 1 are threadedly connected to a first threaded post 17 and a second threaded post 18, with the first threaded post 17 located at the top of the second threaded post 18. The outer walls of the two first threaded posts 17 are threadedly connected to limit rings 25. The bottom of the load-bearing column 1 is snapped with a base 19. The interior of the base 19 is movably connected to several springs 20. The top of the several springs 20 is movably connected to a load-bearing plate 21. The top of the load-bearing plate 21 is fixedly connected to a fixing slot 24. The two sides of the top of the base 19 are fixedly connected to horizontal slots 23. The bottom of the base 19 is movably connected to an anti-damage pad 22.

[0033] In this embodiment, as Figure 1 As shown, the fixing block 3 forms a threaded structure with the load-bearing column 1 through the lead screw 2. The user can lift the entire kettlebell for exercise by using the lifting ring 4 located at the top of the fixing block 3.

[0034] In this embodiment, as Figure 2As shown, the third counterweight 7 is located on top of the second counterweight 6, and the second counterweight 6 is located on top of the first counterweight 5. The first counterweight 5, the second counterweight 6, and the third counterweight 7 all form a sleeve structure with the load-bearing column 1. By sleeved the first counterweight 5, the second counterweight 6, and the third counterweight 7 onto the load-bearing column 1, the user can change the number of load-bearing plates to better suit different users.

[0035] In this embodiment, as Figure 3 As shown, the first retaining ring 8 and the second retaining ring 9 form a rotating structure through the first rotating shaft 12. The first retaining ring 8 and the second retaining ring 9 can be rotatably connected through the first rotating shaft 12, which can effectively fit the two retaining rings onto the top of the load-bearing column 1.

[0036] In this embodiment, as Figure 3 As shown, the first retaining ring 8 and the second retaining ring 9 form a locking structure through the buckle 10 and the pin 11. The pin 11 is inserted into the buckle 10. By turning the buckle 10, the pin 11 can be locked in place, which can prevent the two retaining rings from loosening and also facilitate the disassembly of the kettlebell.

[0037] In this embodiment, as Figure 2 As shown, the first retaining ring 8 and the second retaining ring 9 are located at the top of the outer wall of the load-bearing column 1 and form a sleeve structure. By snapping the two retaining rings onto the top of the load-bearing column 1, the counterweight plate at the bottom can be prevented from swaying back and forth, and the counterweight plate can be stacked or reduced.

[0038] In this embodiment, as Figure 6 As shown, several springs 20 are evenly distributed at the bottom of the load-bearing plate 21 and form an elastic structure. By adding springs 20 inside the base 19, the kettlebell can be placed inside the base 19 when it is not used in the kettlebell form. The cushioning effect of the springs 20 can reduce damage to the base 19 and extend its service life.

[0039] In this embodiment, as Figure 5 As shown, two second threaded posts 18 are symmetrically distributed at both ends of the load-bearing post 1. The limiting ring 25 is located on the outer wall of the first threaded post 17. The second threaded posts 18 form a threaded structure with the load-bearing post 1 through the threaded groove 16. The limiting ring 25 is threadedly connected to the first threaded post 17. By threading the second threaded posts 18 to the load-bearing post 1, and then placing a counterweight plate on the outer surface of the first threaded post 17, the counterweight plate can be fixed by the limiting ring 25 to prevent it from shaking. This allows the kettlebell to be converted into a dumbbell shape.

[0040] In this embodiment, as Figure 5As shown, two horizontal slots 23 are symmetrically distributed on both sides of the base 19, and the horizontal slots 23 and the load-bearing column 1 form a snap-fit ​​structure. By fixing the horizontal slots 23 on the top of the base 19, when the dumbbell form is not in use, the load-bearing column 1 can be placed horizontally on the top of the base 19 and snapped into the horizontal slots 23, which can prevent damage to the ground and make it convenient for the user to grip.

[0041] In this embodiment, as Figure 1 As shown, the baffle 15 and the load-bearing column 1 form an integrated structure, and the load-bearing column 1 forms a snap-fit ​​structure with the fixing slot 24 through the baffle 15. By specifying the baffle 15 at both ends of the load-bearing column 1, it can prevent the counterweight plates on both sides from moving to the middle when in dumbbell form, thus preventing accidental injury to the user. When the kettlebell form is not in use, the baffle 15 at the bottom end can be snapped with the fixing slot 24 at the top of the load-bearing plate 21 to prevent it from being unstable.

[0042] In summary, this easily detachable and weight-adjustable kettlebell allows the user to remove the screw 2 from the top of the support column 1 by rotating the lifting ring 4 on the top of the fixing block 3. The user then places the first counterweight 5, the second counterweight 6, and the third counterweight 7 onto the outer wall of the support column 1 according to their weight tolerance. The locking ring structure, connected by the first locking ring 8 and the second locking ring 9 via the first rotating shaft 12, is then locked onto the top of the support column 1. A lever 10 is connected to one end of the first locking ring 8 via the third rotating shaft 14, and a pin 11 is connected to one end of the second locking ring 9 via the second rotating shaft 13. By levering the lever 10, the pin 11 is locked, firmly fixing the weight plates and preventing wobbling during use. Finally, the screw 2 is threaded onto the top of the support column 1, and the user holds the lifting ring 4 for use. When not using the kettlebell... In its normal operating state, the two second threaded posts 18 are connected to the load-bearing column 1 by removing the lead screw 2 and placing them inside the threaded grooves 16 at both ends. Then, the first counterweight 5, the second counterweight 6, and the third counterweight 7 are fitted onto the outside of the first threaded post 17. The counterweights are fixed to the first threaded post 17 using the limiting ring 25. The baffles 15 at both ends of the load-bearing column 1 can prevent the counterweights from shaking. When the load-bearing column 1 is in kettlebell mode, the baffles 15 at the bottom of the load-bearing column 1 are engaged with the fixing slots 24 above the load-bearing plate 21 inside the base 19 to prevent it from tipping over. The spring 20 at the bottom of the load-bearing plate 21 can cushion the weight when it is pressed down. When the load-bearing column 1 is in dumbbell mode, it can be horizontally locked inside the horizontal slot 23 when not in use. The anti-damage pad 22 at the bottom of the base 19 can prevent the base 19 from being damaged by friction with the ground.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
