Description

Technical Field

[0001] This utility model relates to a kettlebell handle, a dumbbell, and a fitness device for strength training. Background Technology

[0002] Chinese patent document CN220385691U discloses a counterweight connection structure and an adjustable weight dumbbell. The connection structure is used to achieve a detachable connection between two counterweights. One counterweight is provided with a locking groove, and the other counterweight is provided with a locking part that can be embedded in the locking groove. The two counterweights can be operated to rotate relative to each other, so that the locking part can rotate relative to the locking groove between a locked position and a released position. When the locking part is in the locked position, the locking part and the locking groove cooperate to prevent the two counterweights from disengaging from each other. When the locking groove is in the released position, the two counterweights can be separated from each other. One counterweight is provided with a button that can swing between the locked and released states and an elastic element that drives the button to swing to the locked state. The other counterweight is provided with a locking groove. The front end of the button in the locked state can be embedded in the locking groove to restrict the relative rotation of the two counterweights and keep the locking part in the locked position. The dumbbell with the above structure cannot be used for kettlebell exercises. Summary of the Invention

[0003] The purpose of this utility model is to provide a kettlebell handle that can be detachably connected to other counterweight components with holes to form a kettlebell.

[0004] A kettlebell handle includes a handle body having two downwardly extending ends, characterized in that: mounting seats are provided at both ends of the handle body, the mounting seats are provided with connectors, and the connectors are provided with a first connecting structure for detachably connecting with holes by relative rotation.

[0005] In the above scheme, the connectors at both ends of the handle body are provided with a first connecting structure for detachable connection with the hole by relative rotation. The hole is also provided with a second connecting structure that can cooperate with the first connecting structure. In this way, the connector can be detachably connected with other counterweight components with holes to form a kettlebell.

[0006] The connector is movably mounted on the mounting base, which has a flat lower end surface. The connector includes a connecting section that can extend out of the lower end surface or retract into the mounting base. The connecting section is provided with the first connecting structure. When the lower end surface of the mounting base is supported on the ground, the connecting section is compressed and retracted into the mounting base. This allows the kettlebell handle to be used as a push-up grip, meaning the user can bend over and grip the handle body of the kettlebell handle, so that the lower end surfaces of the two mounting bases are supported on the ground, allowing for push-up exercises with up-and-down movements.

[0007] It also includes an elastic element for driving the connecting section back into the mounting base, the elastic element allowing the connecting section to extend for detachable connection with other counterweight components having holes.

[0008] The connector includes a cylindrical body with a closed lower end and an open upper end. The mounting base has a positioning hole that runs vertically through the top and bottom. The cylindrical body is movably fitted into the positioning hole from top to bottom, and the lower section of the cylindrical body can extend out of the lower end face to form the connecting section. This structure facilitates the assembly of the product.

[0009] The connector includes a guide limiting part disposed on the outside of the cylinder, and the mounting base includes an annular inner wall forming a positioning hole. A downwardly extending guide notch is formed along the upper edge of the annular inner wall, and the guide limiting part is fitted into the guide notch. This structure facilitates the assembly of the product.

[0010] A helical spring is provided in the cylinder and compressed between the cylinder and the handle end. The helical spring is used to drive the lower section of the cylinder to extend out of the lower end face. This structure facilitates the positioning and installation of the helical spring.

[0011] The first connection structure is an external thread provided on the outer circumferential surface of the connector, that is, the hole connected to the connector is provided with an internal thread. The connector and the hole are connected by the thread, which has the advantages of simple structure, low cost, and reliable and stable connection. Here, the external thread refers to a wide-pitch thread or a thread-like protrusion formed on the outer circumferential surface of the connector. The wide-pitch thread and the thread-like protrusion are both for the purpose of: rotating the counterweight A by a small angle can realize the complete screwing connection of the connector with the holes of other components.

[0012] The mounting base is rotatably mounted on the end of the handle body about a vertical axis. Rotating the mounting base will cause the connector to rotate as well, thereby enabling the connector to be detachably connected to the hole.

[0013] The upper end of the mounting base has an annular groove, and the end of the handle body is provided with an annular transition part that is embedded in the annular groove. An elastic washer is provided between the annular transition part and the annular groove. The elastic washer can eliminate the installation gap between the handle body and the mounting base, reduce noise, and play a buffering role.

[0014] A dumbbell includes a handle and two counterweights disposed at both ends of the handle. The counterweights are characterized in that: each counterweight has a mounting hole, and the mounting hole has a second connecting structure that can be detachably connected to the first connecting structure, so that the connecting piece on the handle of the kettlebell can be detachably connected to the mounting hole of the counterweight, thereby forming a kettlebell.

[0015] The first connection structure is an external thread, and the second connection structure is an internal thread.

[0016] The counterweight has a mounting hole that extends vertically along its axial direction. The first connecting structure is an external thread, and the upper and lower sections of the mounting hole are provided with internal threads that can mate with the first connecting structure. In this way, the upper and lower ends of the counterweight can be detachably connected to the connecting member.

[0017] A fitness device includes a kettlebell handle and a dumbbell, the kettlebell handle and the dumbbell being able to be used together with the kettlebell, while the dumbbell can also be used separately. Attached Figure Description

[0027] Reference Figures 1 to 8 As shown, a kettlebell handle 1 includes a handle body 11 with two downwardly extending ends. The two ends of the handle body 11 are provided with rotatable mounting seats 12. An annular groove 121 is formed on the upper end of the mounting seat 12. An annular transition portion 111 is provided at the end of the handle body 1, which is embedded in the annular groove 121. An elastic washer 3 is provided between the annular transition portion 111 and the annular groove 121. The elastic washer 3 can eliminate the installation gap between the handle body 11 and the mounting seat 12, reduce noise, and play a buffering role. Specifically, a rubber ring or a silicone ring can be used.

[0028] The mounting base 12 is provided with a connector 13, which has a first connecting structure for detachable connection with the hole via relative rotation. The connector 13 is movably mounted on the mounting base 12. The mounting base 12 has a flat lower end surface. The connector 13 includes a connecting section 13a that can extend out of the lower end surface or retract into the mounting base 12. The connecting section 13a is provided with the first connecting structure. An elastic member is provided between the connector 13 and the end of the handle body 11 for driving the connecting section 13a to retract. The connector 13 includes a cylindrical body 133 whose lower end closes the upper opening. The mounting base 12 forms a vertically penetrating positioning hole 12a. The cylinder 133 is movably fitted into the positioning hole 12a from top to bottom, and the lower section of the cylinder 133 can extend out of the lower end face to form the connecting section 13a. The connecting member 13 includes a guide limiting part 132 provided on the outside of the cylinder 133. The mounting base 12 includes an annular inner wall 122 that forms the positioning hole 12a. A downwardly extending guide notch 123 is formed on the upper edge of the annular inner wall 122. The guide limiting part 132 is fitted in the guide notch 123. The elastic element is a helical spring 14 provided in the cylinder 133 and compressed between the cylinder 133 and the end of the handle body 11. The helical spring 14 is used to drive the lower section of the cylinder 133 to extend out of the lower end face 12b.

[0029] When the lower end face 12b of the mounting base 12 is supported on the ground, the connecting section 13a is compressed and can be retracted into the mounting base 12. This allows the kettlebell handle to be used as a push-up grip, meaning the user can bend over and grip the handle body 11 of the kettlebell handle, so that the lower end faces 12b of the two mounting bases 12 are supported on the ground, allowing for push-up exercises with up-and-down movements.

[0030] In the above scheme, the connectors 13 at both ends of the handle body 11 are provided with a first connecting structure for detachable connection with the hole by relative rotation. The hole is also provided with a second connecting structure that can cooperate with the first connecting structure. In this way, the connectors 13 can be detachably connected with other counterweight components with holes to form a kettlebell.

[0031] The first connection structure is an external thread 131 provided in the connection section 13a, that is, the hole connected to the connector 13 is provided with an internal thread. The connector 13 and the hole are connected by a thread, which has the advantages of simple structure, low cost, and reliable and stable connection. Here, the external thread 131 refers to a wide-pitch thread or a thread-like protrusion formed on the outer circumferential surface of the connector. The wide-pitch thread and the thread-like protrusion are both for the purpose of: rotating the counterweight A by a small angle can realize the complete screwing connection of the connector with the holes of other components. In this embodiment, a thread-like protrusion is used.

[0032] A dumbbell 2 includes a handle 21 and two counterweights 22 disposed at both ends of the handle 21. The counterweights 22 have a through mounting hole 22a in the middle, and the mounting hole 22a has an internal thread 222. The upper and lower sections of the mounting hole 22a are provided with internal threads 222 that can mate with the external threads 131 of the connecting section 13a. The counterweights 22 include an annular shell 221 and an annular counterweight block 223 disposed in the annular shell 221.

[0033] A fitness device includes a kettlebell handle 1 and a dumbbell 2. The kettlebell handle 1 and dumbbell 2 can be combined to form a kettlebell, and the dumbbell 2 can also be used alone. When it is necessary to assemble it into a kettlebell, the connecting sections 13a at both ends of the kettlebell handle 1 are aligned with the mounting holes 22a of the counterweights 22 at both ends of the dumbbell 2. Then, the mounting base 12 is rotated to screw the external thread 131 of the connecting section 13a into the internal thread 222 of the mounting hole 22a, thereby combining the kettlebell handle 1 and the dumbbell 2 into a kettlebell.
