[0003] Traditional kettlebells are mostly made of cast iron, but the quality of this kettlebell is fixed, and users need to buy kettlebells of different specifications for exercise. In addition, the kettlebell has a hard surface, which can easily cause injuries to users and damage the ground. Therefore, some kettlebells have a soft shell, which can be filled with weights according to the needs of users. For example, a soft kettlebell disclosed in Chinese utility model patent CN201921596430.9 includes a sphere, and an air injection hole is opened in the middle of the top of the sphere, and a sealing insert is inserted into the air injection hole. A valve core is installed, and the bottom air outlet of the valve core is sealed and connected with the inside of the sphere, the surface of the air injection hole is threadedly installed with a valve mounting cover, rubber handle mounting rings are fixedly installed on both sides of the top of the sphere, a carrying handle is connected to the inside of the handle mounting ring, and the other end of the carrying handle passes through a through hole opened in the middle of the handle mounting ring, a sub-Velcro is sewn on the middle surface of the carrying handle, a strap is wrapped around the surface of the sub-Velcro, and a mother Velcro bonded and fixed to the sub-Velcro is sewn on the back of the strap.
[0004] The above-mentioned kettlebell is easy for users to adjust the mass and is suitable for different users. However, in this structure, the counterweight is filled into the sphere through a valve core, which is not convenient for rapid adjustment of the overall mass of the kettlebell. In addition, since the sphere is made of PVC rubber material, the handle mounting ring is subjected to greater force during use and is easily deformed and damaged after long-term use, thereby affecting the appearance and service life of the kettlebell.

DETAILED DESCRIPTION
[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:
[0031] See also Figures 1 to 9 As shown, a kettlebell includes an upper shell 2 and a lower shell 1 that are detachably connected. A handle portion 23 is provided on the upper shell 2. A storage cavity 13 for storing weights is formed between the upper shell 2 and the lower shell 1. The detachable upper shell 2 and the lower shell 1 facilitate rapid adjustment and replacement of weights, making it convenient for users to use the kettlebell. The flexible base 11 can reduce the collision between the kettlebell and the ground, avoid damage to the ground, and reduce the occurrence of the kettlebell hitting the user. The weights can be heavy objects such as metal blocks, sand or water.
[0032] The lower shell 1 includes a flexible base 11 and a hard connecting seat 12. The flexible base 11 and the hard connecting seat 12 are fixedly arranged, and the upper shell 2 and the hard connecting seat 12 are detachably connected. The flexible base 11 can reduce the collision between the kettlebell and the ground, avoid damage to the ground, and reduce the occurrence of the kettlebell hitting the user. The hard connecting seat 12 facilitates the stable connection between the upper shell 2 and the lower shell 1, avoids deformation of the connection position of the upper shell 2 and the lower shell 1 during use, and affects the stable connection between the upper shell 2 and the lower shell 1, which is convenient for users to use.
[0033] In the utility model, the flexible base 11 and the hard connection seat 12 can be connected by fasteners. In this embodiment, the flexible base 11 and the hard connection seat 12 can also be integrally injection molded. The integral injection molding structure facilitates the tight connection between the flexible base 11 and the hard connection seat 12, avoiding the separation of the flexible base 11 and the hard connection seat 12 during use, which is beneficial to extending the service life of the kettlebell.
[0034] The upper shell 2 and the lower shell 1 can be connected by a snap-fit structure, and the upper shell 2 and the lower shell 1 can also be connected by a threaded structure. The hard connecting seat 12 in this embodiment includes a fixing portion 123 connected to the flexible base 11, and the fixing portion 123 extends to form a connecting flange 121, and the connecting flange 121 is provided with a first threaded portion 122. The upper shell 2 is provided with a second threaded portion 24 adapted to the first threaded portion 122. The setting of the first threaded portion 122 and the second threaded portion 24 facilitates the close installation of the upper shell 2 and the lower shell 1, prevents counterweights such as sand or water from detaching from the storage cavity 13, and prevents the upper shell 2 and the lower shell 1 from accidentally detaching during use.
[0035] The flexible base 11 described in the utility model is provided with an elastic supporting surface 111, and the upper shell 2 is provided with a pressing surface 25, the pressing surface 25 presses against the elastic supporting surface 111 and makes the first threaded portion 122 and the second threaded portion 24 tightly connected. The setting of the elastic supporting surface 111 and the pressing surface 25 facilitates the tight connection of the first threaded portion 122 and the second threaded portion 24, and avoids excessive relative force between the first threaded portion 122 and the second threaded portion 24 affecting the relative disassembly of the upper shell 2 and the lower shell 1.
[0036] Preferably, a step portion 124 is provided on the hard connecting seat 12, and the elastic supporting surface 111 extends above the step portion 124. When the upper shell 2 and the lower shell 1 are connected, the pressing surface 25 and the step portion 124 will respectively abut against the two sides of the elastic supporting surface 111, thereby preventing the flexible base 11 and the hard connecting seat 12 from accidentally detaching during fitness, which is beneficial to extending the service life of the kettlebell.
[0037] In this embodiment, the upper shell 2 is sleeved on the outer periphery of the hard connection seat 12, and the hard connection seat 12 is embedded in the inner side of the flexible base 11. The tightening surface 25 is against the elastic supporting surface 111 and the hard connection seat 12 is hidden. The hidden hard connection seat 12 can prevent debris or users from causing the connection position of the flexible base 11 and the hard connection seat 12 to be separated, which is conducive to the tight connection between the flexible base 11 and the hard connection seat 12.
[0038] The upper shell 2 includes a left half shell 21 and a right half shell 22 that are detachably connected, and a handle portion 23 is provided on the left half shell 21 and the right half shell 22. The left half shell 21 and the right half shell 22 are respectively provided with a sealing ridge 211 and a sealing groove 221 that cooperate with each other, and the sealing groove 221 is annular or the two ends of the sealing groove 221 extend to both sides of the hard connection seat 12 respectively. The detachably connected left half shell 21 and the right half shell 22 are convenient for the production and processing of the upper shell 2, and the setting of the sealing ridge 211 and the sealing groove 221 can prevent counterweights such as sand or water from escaping from the storage cavity 13, which is convenient for users to use.
[0039] In this embodiment, the left half shell 21 and the right half shell 22 are both provided with a tightening surface 25 and a second threaded portion 24, and the left half shell 21 and the right half shell 22 are respectively provided with a connecting portion 212 and a connecting groove 222, and the connecting portion 212 cooperates with the connecting groove 222 to position and connect the left half shell 21 and the right half shell 22, and the fastener passes through the connecting portion 212 and the connecting groove 222 to relatively fix the left half shell 21 and the right half shell 22.
[0040] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
