Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, specifically to soft kettlebells. Background Technology
[0002] Exercise is a beneficial activity for both the body and mind. Among the various forms of exercise, weightlifting aims to develop the strength and size of skeletal muscles. Weightlifting utilizes weight acting on a physical object to counteract the forces generated by muscles.
[0003] Kettlebells are a type of fitness equipment used for weightlifting training. When using kettlebells, various pushing, lifting, raising, throwing, and snatching exercises can be performed, all teaching users to control and manage the momentum of the kettlebell. This skill can then be transferred into abilities used in sports, work, leisure, and other daily life activities. Kettlebells are extremely effective in comprehensively improving overall explosive power and endurance in aerobic training. More importantly, kettlebells can train muscles not used in other sports. However, due to their material, kettlebells are prone to damage during use, reducing their lifespan, and they cannot be adjusted to the desired weight, thus reducing their efficiency.

[0019] Figure 1 This is a schematic diagram of the structure of Example 1;
[0020] Figure 2 This is a cross-sectional view of the protective component in this utility model.
[0021] The diagram shows: PU shell 1, through hole 2, base 3, handle 4, protective component 5, fiber mesh cloth 51, anti-collision cotton 52, microfiber leather 53, connecting cover 6. Detailed Implementation
[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention. Example 1
[0023] A soft kettlebell according to this utility model includes: a PU shell 1, a through hole 2, a base 3, a handle 4, and a protective component 5. The PU shell 1 has a through hole 2, and a matching connecting cap 6 is rotatably connected to the through hole 2. A threaded ring is provided around the perimeter of the through hole 2, and a threaded ring is provided at the bottom of the connecting cap 6. The connecting cap 6 is threadedly connected to the through hole 2. A certain weight of filling material is injected into the PU shell 1 through the through hole 2, allowing the PU shell 1 to update its weight at any time, improving exercise efficiency. The outer surface of the connecting cap 6 and the outer surface of the protective component 5 are kept at the same horizontal line, ensuring the smoothness of the overall surface and improving aesthetics. The handle 4 is connected to the PU shell 1 and has an anti-slip pad for effective anti-slip and easy lifting during exercise. Buckles are provided at both ends of the handle 4, and the handle 4 is inserted into the fixing holes of the PU shell 1 through the buckles. The base 3 is located at the bottom center of the PU shell 1, facilitating placement of the PU shell 1 and improving overall stability. The outer surface of the PU shell 1 is covered with a protective component 5, which can effectively protect the outer surface of the PU shell 1 and improve its service life.
[0024] The protective component 5 includes a fiber mesh fabric 51, impact-absorbing cotton 52, and microfiber leather 53. One side of the fiber mesh fabric 51 is bonded to the PU shell 1, and the other side is bonded to the impact-absorbing cotton 52, which has a thickness of 3-8mm. Microfiber leather 53 is bonded to the impact-absorbing cotton 52. The fiber mesh fabric 51 effectively strengthens the connection between the PU shell 1 and the impact-absorbing cotton 52, enhancing adhesion and improving impact resistance. Combined with the use of microfiber leather 53, it effectively strengthens the overall structure's wear resistance, enhances the structure's softness against the skin, and extends its service life. Example 2
[0025] This embodiment 2 is based on embodiment 1, mainly with some structural changes to the handle 4, specifically: the handle 4 is integrally molded with the PU shell 1. This integral molding structure effectively enhances the stability and robustness of the overall structure, and the PU material effectively strengthens its wear resistance.
