Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of fitness equipment, and more specifically, to a magnetic resistance kettlebell. Background Art
[0002] In the context of national fitness, many outdoor public places are equipped with training equipment, and kettlebells are one of them. Traditional kettlebells use their own weight as a training load, so they are usually heavy. If the user makes a mistake in operation, it is easy to hurt themselves. Therefore, for safety and anti-theft reasons, a kettlebell that uses magnetic force for braking has appeared on the market. This kettlebell is mounted on a vertical metal column, and a magnet is installed inside the kettlebell. When the user accidentally drops the kettlebell, the internal magnet induces current in the metal column during the rapid fall of the kettlebell, and generates resistance to the kettlebell through electromagnetic action, thereby reducing the impact force when the kettlebell falls to the ground and avoiding injury to personnel.
[0003] The current kettlebell has multiple magnets inside, which are fixed to the side wall of a sleeve by gluing or snapping, and then the two half shells are fixed outside the sleeve to form a complete body; when in use, the metal column passes through the sleeve so that the magnet surrounds the metal column. This structure must be produced and assembled in the order of assembling the sleeve with magnets first and then assembling the body. The two links cannot be carried out in parallel, which reduces the flexibility of production; moreover, each magnet is fixed separately, which is very time-consuming and labor-intensive, so the structural design needs to be improved.

In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.
[0037] Please also read Figures 1 to 6 , the magnetic resistance kettlebell provided by the embodiment of the present application is now described. A magnetic resistance kettlebell includes a main body and a magnet assembly. The middle of the main body has a sliding hole suitable for the metal column to pass through, and gripping parts are symmetrically arranged on both sides; the bottom of the main body is also provided with an insertion hole, which is coaxial with and connected to the sliding hole, and the diameter of the insertion hole is larger than the diameter of the sliding hole to form a limiting shoulder. The magnet assembly is inserted into the insertion hole and is limited by the limiting shoulder.
[0038] The magnet assembly includes: a magnet cage, a plurality of arc-shaped magnets and a clamp. The magnet cage is suitable for being inserted into the insertion hole, and the inner hole is suitable for passing through the metal column; the outer wall of the magnet cage is provided with a plurality of mounting grooves, and the plurality of mounting grooves are distributed along the circumference of the magnet cage; the outer periphery of the magnet cage is also provided with a clamp groove, and the clamp groove surrounds the plurality of mounting grooves; the plurality of arc-shaped magnets are installed in each mounting groove one by one; the clamp sleeve is arranged in the clamp groove, and each arc-shaped magnet is clamped tightly in the mounting groove.
[0039] Compared with the prior art, the magnetic resistance kettlebell of the embodiment of the present application is divided into two parts, a main body and a magnet assembly. During production, the two parts can be assembled in parallel without interfering with each other. Finally, the magnet assembly is inserted into the insertion hole at the bottom of the main body, which improves the flexibility of assembly and facilitates production arrangements.
[0040] The magnet assembly uses a magnet cage to fix each magnet, and the clamp clamps multiple magnets in the installation groove of the magnet cage, making the assembly of the magnet more convenient and improving production efficiency.
[0041] In specific implementation, the main body, as the main load of training, has a certain weight. The main body part can be a metal shell; according to the required weight, a certain counterweight block can be added inside the shell. A vertical center tube is installed in the center of the main body. The center tube is divided into two sections, the upper section has a smaller inner diameter as a sliding hole, and the lower section has a larger inner diameter as an insertion hole. The connecting part of the upper and lower sections forms an annular limit shoulder. When the magnet assembly is inserted into the insertion hole, one end abuts against the limit shoulder, thereby fixing the insertion depth of the magnet assembly.
[0042] The magnet cage of the magnet assembly can be made by cutting a plurality of mounting grooves on the outer wall of a round tube. During installation, each arc-shaped magnet is placed in the corresponding mounting groove, and then the clamp is clamped into the clamp groove on the magnet cage, so that the clamp clamps each arc-shaped magnet to the mounting groove at one time, eliminating the trouble of fixing each magnet individually. The clamp is a circular ring structure with a notch, which is easier to expand and sleeve on the magnet cage.
[0043] Since the side wall of the magnet cage is arc-shaped, the mounting slot also has a certain curvature. The arc-shaped magnet can be more compatible with the mounting slot, and it is also convenient for the clamp to tighten each arc-shaped magnet.
[0044] As a specific embodiment of the magnetic resistance kettlebell provided in the present application, a linear sliding bearing suitable for cooperating with the metal column is provided in the sliding hole.

[0047] See also Figure 4 and Figure 5 As a specific embodiment of the magnetic resistance kettlebell provided in the present application, the bottom of the mounting groove is open, and the side wall of the bottom of the mounting groove is provided with a limiting portion, which limits the depth of the arc-shaped magnet entering the mounting groove.
[0048] In this embodiment, the bottom of the installation slot is open, so that the magnetic field of the arc magnet can directly form an induction with the metal column, reducing the obstruction of the magnetic field by the magnet cage. The setting of the limiter can limit the depth of the arc magnet entering the installation slot, thereby avoiding interference between the arc magnet and the metal column inserted into the inner hole of the magnet cage.
[0049] As a specific embodiment of the magnetic resistance kettlebell provided in the present application, linear sliding bearings suitable for cooperating with the metal column are respectively provided at both ends of the inner hole of the magnet cage.
[0050] In this embodiment, when the main body slides up and down along the metal column, the magnet cage and the metal column can also slide smoothly, reducing resistance. Figure 5 (Linear slide bearings not shown).

[0052] In this embodiment, the cover plate is a metal flat plate, which has the same shape as the main body ground, and a notch is set in the middle. After the cover plate is installed to the bottom of the main body, the magnet assembly is limited in the insertion hole, and the notch in the middle of the cover plate faces the inner hole of the magnet cage.
[0053] See also Figure 5 As a specific embodiment of the magnetic resistance kettlebell provided in the present application, clamp grooves are respectively provided at both ends of the magnet cage, and the two clamp grooves respectively surround the two ends of the plurality of mounting grooves;

[0057] The sliding hole penetrates through the thin neck and extends to the round belly portion, and the insertion hole is arranged at the bottom of the round belly portion.
[0058] In this embodiment, the long and thin neck is provided to facilitate the large-sized gripping part, which is convenient for the trainee to hold. At the same time, the length of the sliding hole is also extended, so that the main body can slide up and down along the metal column more smoothly.
[0059] In a specific implementation, the linear sliding bearing in the sliding hole is installed in the thin neck and is spaced far away from the linear sliding bearing in the magnet cage.
[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
