Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a kettlebell with flexible weight adjustment. Background Art

[0002] Now, with the improvement of living standards, people pay more and more attention to physical health. Exercising and keeping fit during the leisure time after work has become the secret for most people to maintain health. As a common fitness equipment, the kettlebell takes up little space when in use and can be used for various exercises such as pushing, lifting, carrying, throwing, and squat jumps, effectively improving the body's explosive power and fully exercising various parts of the user's body.

[0003] However, most of the kettlebells on the market are of an integral structure with a fixed weight. When people need to use kettlebells of different weights to exercise different parts of the body, they can only purchase multiple kettlebells of different weights for use, which greatly increases the purchase cost for users. Moreover, kettlebells of different weights occupy different amounts of space, making the storage and carrying of kettlebells extremely inconvenient. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a kettlebell with flexible weight adjustment, which solves the problems that traditional kettlebells cannot adjust their weights and occupy too much space.

[0005] The technical solution adopted by the utility model is as follows: A kettlebell with flexible weight adjustment includes an upper shell and a lower shell. The upper shell and the lower shell are movably connected. A handle is detachably connected to the upper shell. The lower shell includes a bottom shell, and the bottom shell is made of a soft material.

[0006] Through the above technical solution, the user can put a counterweight in the form of fine sand or iron sand of appropriate weight into the lower shell, install the handle on the upper shell, and then assemble the upper shell and the lower shell. After the user finishes assembling the upper shell and the lower shell, they can use the kettlebell for physical exercise. By adjusting the weight of the counterweight in the lower shell, the weight of the kettlebell can be changed, greatly reducing the cost for the user to use kettlebells of different weights. The user only needs one kettlebell to perform various weight exercises, saving the space occupied by traditional kettlebells of different weights and being very convenient to use. Moreover, the soft material of the bottom shell greatly reduces the collision between the counterweight and the bottom shell when the kettlebell is in use, extending the service life of the kettlebell.

[0007] Further, the lower shell further includes a cylindrical part. The cylindrical part is connected to the bottom shell. The cylindrical part is made of a hard material, and the upper shell is made of a hard material.

[0008] With the above technical solution, the cylindrical part of the hard material makes the overall structure of the upper shell and the lower shell better sealed after connection, avoiding the generation of gaps between the upper shell and the lower shell, which may cause the counterweight to leak and affect the use of the kettlebell.

[0009] Further, a clamping groove is provided on the outer side of the cylindrical part, and a limiting protrusion is correspondingly provided on the bottom shell, and the clamping groove and the limiting protrusion are clamped; the cylindrical part and the bottom shell are clamped and heat-melted and connected.

[0010] With the above technical solution, the installation of the cylindrical part and the bottom shell can be completed by clamping the clamping groove and the limiting protrusion, which is convenient for factory production and assembly, and also makes the stress structure of the cylindrical part and the bottom shell better. After being heat-melted into the lower shell, the overall stress is more balanced and it is more stable to use.

[0011] Further, the upper shell and the lower shell are connected by clamping, threaded connection or plug-in connection.

[0012] With the above technical solution, the connection method of the upper shell and the lower shell by clamping, threaded connection or plug-in connection makes the assembly and separation of the upper shell and the lower shell faster and more convenient to use.

[0013] Further, connection holes are provided at both ends of the handle, and mounting holes are correspondingly provided on the upper shell, and screws are commonly inserted into the connection holes and the mounting holes.

[0014] With the above technical solution, the user can connect the handle and the upper shell by inserting screws into the connection holes and the mounting holes, making the disassembly and installation of the handle and the upper shell very convenient.

[0015] Further, positioning grooves are provided on the upper shell, the number of the positioning grooves is two, and the two positioning grooves are respectively located at the connection between the two ends of the handle and the upper shell. The positioning grooves are clamped with the ends of the handle, and the mounting holes are arranged in the positioning grooves.

[0016] With the above technical solution, the user only needs to respectively clamp the two ends of the handle into the positioning grooves of the upper shell and then use screws to fix it to complete the installation of the handle, avoiding the deviation of the handle during installation by the user, resulting in the handle not being installed in place and affecting the normal use of the kettlebell.

[0017] Further, an inner cavity is formed by connecting the upper shell and the lower shell, and the inner cavity can accommodate the handle.

[0018] With the above technical solution, when the user stores the kettlebell, the user can remove the handle from the upper cover and then place the handle in the inner cavity, greatly reducing the space occupied by the kettlebell, and it is more convenient for the user to store and carry the kettlebell.
