Description

Technical Field

[0001] The utility model belongs to the field of fitness equipment, in particular to a fitness soft kettlebell with adjustable weight. Background Art

[0002] Soft kettlebells (also known as yoga balls or fitness balls) are a popular fitness tool that is mainly used for training to enhance core strength, improve body balance and flexibility. It is usually a rubber ball filled with gas or soft fillers (such as fine sand, plastic particles, etc.). The diameter can range from 15 cm to 50 cm, and the weight ranges from 2 kg to 20 kg, depending on the needs of the user and the purpose of the exercise. Soft kettlebells can be used for various gymnastic movements, such as plank support, push-ups, crunches, etc., to help people train their whole body. Due to the instability of the ball, the use of soft kettlebells can better activate the core muscles and improve body coordination and balance. For people in the recovery period, soft kettlebells are helpful for low-impact restorative exercises and relieve joint pressure. By sitting on the ball and doing stretching exercises, the range of motion of the joints can be increased and flexibility can be improved. Soft kettlebells are small in size and easy to store at home or in the gym, suitable for environments with limited space. The existing soft kettlebells have only one accommodating cavity, and the filling port of the soft kettlebells on the market is mostly located at the bottom of the sphere. Because the filling port at the bottom is relatively small, it can only be filled by professional equipment. Usually, special equipment is used to pour weights such as iron sand or yellow sand into the sphere by pressure. Consumers cannot fill it by themselves after buying it home. Therefore, the current soft kettlebells can only have one product and one weight, and cannot take into account both. This will cause the sphere to only meet the exercise needs of a certain specific weight, and the weight cannot be adjusted. For people of different ages or different exercise needs, they need to buy multiple soft kettlebells that can only meet a certain weight standard, which is inconvenient for family use. Utility Model Content

[0003] In view of the problem that the existing soft kettlebell has only one accommodating cavity and cannot adjust the weight, the utility model provides a soft fitness kettlebell with adjustable weight. By arranging at least two accommodating cavities inside the soft kettlebell, the weight of the ball can be changed by filling contents into different cavities.

[0004] The utility model adopts the following technical solution: a weight-adjustable fitness soft kettlebell, comprising a handle portion that can be held in hand and a sphere connected to the handle portion, wherein at least one partition wall is provided in the sphere, and the partition wall divides the sphere into at least two mutually separated accommodating cavities, and each accommodating cavity corresponds to a filling port, through which fillers can be added to the corresponding accommodating cavities respectively.

[0005] By setting a partition wall, the sphere is divided into at least two separate accommodation cavities, and each accommodation cavity is provided with a filling port. Through the filling port, fillers (such as iron sand, fine sand, plastic particles, water, etc.) can be added to the corresponding accommodation cavity. When one of the accommodation cavities is filled with fillers, the other accommodation cavities can be used as weight-adjusting cavities. For example, when the elderly or children with less strength are exercising, one of the accommodation cavities can be filled, and when young and middle-aged people with greater strength are exercising, other accommodation cavities can be partially or fully filled as needed. In this way, the purpose of weight adjustment can be achieved, and only one fitness soft kettlebell can meet the fitness needs of the whole family, broadening the applicable population and usage scenarios.

[0006] As a preferred solution, the filling port includes a hollow column embedded in the sphere. The sphere is wrapped around the outside of the hollow column, and a blocking section is formed at the end face of the hollow column. The blocking section is annular, and the hollow area surrounded by it forms a relief hole. If the filling port is a soft hole, the internal filler is easily squeezed out during sealing and cannot provide strong support. The hollow column has a certain hardness, provides a certain support force for the soft sphere, and is not easily detached when integrated with the sphere. The blocking section can effectively prevent the hollow column from coming out, and a sealing plug can be stuffed into the hollow column through the relief hole. In this application, the material of the hollow column is PVC and is integrally formed with the sphere during production, that is, the outer wall of the hollow column is wrapped by the raw material of the sphere during heating and is integrated after cooling.

[0007] Furthermore, a sealing plug can be stuffed into the hollow column through the relief hole. Using this sealing plug can achieve removing, opening, stuffing, or sealing the filling port. The sealing plug has a through hole, and the through hole is adapted to the position of the relief hole and serves as the air hole of the sphere. By removing or stuffing the sealing plug, the filling port can be in an open or sealed state. Through the air hole, air can be pumped into the sphere. When filling is required, a tool can be used to hook out the sealing plug at the air hole and then fill the sphere with fillers.

[0008] As another preferred solution, the filling port includes a through hole provided on the sphere, and a cover with a handle is provided at the through hole. The cover is provided with an elastic stuffing part, and the stuffing part can stuff the through hole to form a seal.

[0009] As a third preferred solution, the filling port includes a threaded hole provided on the sphere, and an end cap is fitted at the threaded hole. By rotating the end cap, the filling port can be opened for filling or the threaded hole can be sealed. The end cap has a horizontally placed handle for convenient application of force during operation.

[0010] As a preferred solution, there is one partition wall, which is planar and horizontally disposed inside the sphere, and two accommodating cavities are correspondingly formed inside the sphere and arranged one above the other, and the handle portion is disposed outside the upper accommodating cavity.

[0011] Furthermore, the volumes of the two accommodating cavities arranged one above the other are different. Preferably, the upper accommodating cavity is smaller than the lower accommodating cavity. Substances such as iron sand and fine sand can be filled in the lower accommodating cavity to lower the center of gravity.

[0012] As another preferred solution, there is one partition wall, which is planar and longitudinally disposed inside the sphere, and two accommodating cavities are correspondingly formed inside the sphere and arranged side by side horizontally.

[0013] Furthermore, the two accommodating cavities are of equal size.

[0014] As a third preferred solution, there is one partition wall, which is curved and smoothly connected inside the sphere.

[0015] Furthermore, the wall thicknesses of the sphere corresponding to different accommodating cavities are different.

[0016] The beneficial effects of the present utility model are as follows: This application is an adjustable-weight fitness soft kettlebell. By providing a partition wall, the sphere is divided into at least two separate accommodating cavities, and each accommodating cavity is provided with a filling port. When one of the accommodating cavities is filled with a filler, the other accommodating cavities are used as cavities for adjusting the weight, so that the purpose of adjusting the weight can be achieved. Using only one fitness soft kettlebell can meet the fitness needs of the whole family, expanding the applicable population and usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] The following combines the accompanying drawings of the present utility model to explain and illustrate the technical solutions of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] This embodiment is an adjustable-weight fitness soft kettlebell. As Figures 1 to 5 shown, it includes a pulling part 1 that can be held by hand and a sphere 2 connected to the pulling part 1. A partition wall 3 is provided inside the sphere 2. There is one partition wall 3, which is planar and horizontally arranged inside the sphere 2, and two vertically arranged accommodating cavities are correspondingly formed inside the sphere 2. The accommodating cavity located above is the first accommodating cavity 21, and the accommodating cavity located below is the second accommodating cavity 22. The pulling part 1 is arranged outside the first accommodating cavity 21, and each accommodating cavity corresponds to a filling port. Fillers can be added into the corresponding accommodating cavity through the filling port.

[0029] By providing the partition wall 3, the sphere 2 is divided into two separate accommodating cavities, and each accommodating cavity is provided with a filling port. Fillers (such as iron sand, fine sand, plastic particles, water, etc.) can be added into the corresponding accommodating cavity through the filling port. When one of the accommodating cavities is filled with fillers, the other accommodating cavity is used as a cavity for adjusting the weight. For example, when the elderly, children, etc. with less strength are exercising, one of the accommodating cavities is filled, and when the young and middle-aged with greater strength are exercising, the other accommodating cavity can be partially or fully filled as needed. In this way, the purpose of adjusting the weight can be achieved, and only one fitness soft kettlebell can meet the fitness needs of the whole family, broadening the applicable population and usage scenarios.

[0030] In this embodiment, the capacities of the two accommodating cavities are equivalent. During actual production, the capacities of the two accommodating cavities can be different, with the upper one larger and the lower one smaller, or the upper one smaller and the lower one larger. Different materials can be filled inside the two accommodating cavities, or the same material can be filled, which can be adjusted according to specific needs.

[0031] In this embodiment, the two accommodating cavities correspond to two filling ports, which are respectively arranged at the bottom and top of the sphere 2. The filling port arranged at the bottom of the sphere 2 includes a hollow column 23 embedded in the sphere 2. The sphere 2 is wrapped outside the hollow column 23, and a blocking section is formed at the end face of the hollow column 23. The blocking section is annular, and the hollow area surrounded by it forms a relief hole 24. If the filling port is a soft hole, the internal filler is easily extruded during plugging and cannot provide strong support. The hollow column 23 has a certain hardness, provides a certain support force for the soft sphere 2, and is not easily detached when integrated with the sphere 2. The blocking section can effectively prevent the hollow column 23 from coming out, and a sealing plug can be stuffed into the hollow column 23 through the relief hole 24. A sealing plug 25 can be stuffed into the hollow column 23 through the relief hole 24. Using this sealing plug 25 can realize removing, opening, stuffing, or sealing the filling port. The sealing plug 25 has a through hole 251, and the through hole 251 is adapted to the position of the relief hole and serves as an air hole of the sphere 2. By removing or stuffing the sealing plug 25, the filling port is in an open or sealed state. Air can be pumped into the sphere through the air hole. When filling is required, a tool can be used to hook out the sealing plug 25 at the air hole, and then the sphere can be filled. The material of the hollow column is PVC, and it is integrally formed with the sphere during production, that is, the outer wall of the hollow column is wrapped by the raw material of the sphere when heated and integrated after cooling. During filling, the filler is added into the sphere through this hollow column, and then a sealing plug made of a rubber material is inserted into the hollow column to play a role in isolation. In this way, the internal filler will not flow out and the air in the sphere will not escape during movement. Because the air sleeve is relatively small and the space proportion it occupies in the lower part of the whole product is also small, it will not have any impact when the bottom of the sphere touches the ground.

[0032] The filling port located at the top of the sphere 2 includes a through hole arranged on the sphere 2. A cover 4 with a handle 42 is arranged at the through hole. The cover 4 is provided with an elastic stuffing part 41, and the stuffing part 41 can stuff the through hole to form a seal. The part of the cover 4 except the stuffing part 41 can cover the through hole, providing better protection for the through hole and preventing sundries from entering the sphere 2. Directly stuffing the stuffing part 41 into the through hole can reduce its installation difficulty.

[0033] The filling port located at the top of the sphere can be Figure 1 The structure shown can also be Figure 6 The structure shown, where Figure 1The packing in it is located on the side of the sphere 2 and is not arranged opposite to the pulling part 1. Figure 6 The packing port in it is located directly below the pulling part 1 and is arranged opposite to the pulling part.

[0034] In this embodiment, the partition wall 3 is formed by a plastic diaphragm 31 arranged in the mold. The specific operation process is as follows: The mold is divided into upper and lower layers and has upper and lower feeding ports. The plastic diaphragm 31 is covered between the two feeding ports. Since the material for forming the sphere 2 is initially liquid, the initial materials entering from the two feeding ports can cover the plastic diaphragm 31 from the upper and lower sides of the plastic diaphragm 31. After solidification, the three are connected as a whole to form the partition wall 3. During the molding process, the wall thickness of the sphere 2 located in different accommodating cavities is adjusted by controlling the amount of material added. The raw materials for preparing the first accommodating cavity 21 and the second accommodating cavity 22 can be selected in different colors. In addition, the plastic diaphragm 31 can also be replaced with a metal film.

[0035] Embodiment 2

[0036] As Figure 7 shown, the difference between this embodiment and Embodiment 1 is that: the partition wall 3 is one and is planar, longitudinally arranged inside the sphere 2, and two horizontally arranged accommodating cavities are correspondingly formed inside the sphere 2.

[0037] Embodiment 3

[0038] As Figure 8 shown, the difference between this embodiment and Embodiment 1 is that: the partition wall 3 is one and is curved, smoothly connected inside the sphere 2.

[0039] Embodiment 4

[0040] The difference between this embodiment and Embodiment 1 (not shown in the figure) is that: the packing port includes a threaded hole provided on the sphere 2, and an end cap is fitted at the threaded hole. The end cap is rotated to open the packing or seal the threaded hole, and the end cap has a horizontally arranged handle for facilitating the application of force during operation.
