Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a fitness device. Background Technology

[0002] Chinese patent document CN222163177U discloses a connection structure for a fitness device, which includes a detachably connected handle and an elastic rod. The elastic rod is provided with a spring part connected to the handle. The handle is provided with a mounting protrusion, and a spiral groove is provided on the outer periphery of the mounting protrusion. The spring part is sleeved on the mounting protrusion and cooperates with the spiral groove. The cooperation between the spring part and the spiral groove fixes the handle and the elastic rod relatively. The reciprocating motion of the handle is controlled by the spring part causing the handle to vibrate.

[0003] Because the elastic bar uses a one-piece, uniform diameter design, the following defects exist in this structure: First, the grips are not interchangeable between elastic bars of different diameters, leading to inconvenience in replacement and maintenance, and waste of resources; Second, the grips are too thick, especially for fitness bars with large elastic bar diameters, resulting in discomfort or insufficient grip strength for the user, leading to distorted movements and reduced exercise efficiency; Third, the length of the elastic bar used to connect with the grip is too short, resulting in a small contact area between the two, which easily leads to a weak connection and loosening during use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fitness device with a structure of helical springs of different diameters integrated into the bar body. This not only facilitates the universal design of the handle, but also makes the fitness device comfortable and powerful to hold during use, and the handle is firmly connected and not easy to loosen.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A fitness device includes a spring tube and a grip portion; the spring tube is a helical spring tube, comprising a main body with a larger diameter, a first end portion with a smaller diameter located at one end of the main body, and a transition portion connecting the main body and the first end portion, the diameter of which gradually decreases from the main body to the first end portion; the inner circumference of the first end portion is formed with an internally threaded connection hole; the grip portion includes a handle body, a handle front end component located at the front end of the handle body, and a handle tail end component located at the rear end of the handle body; the handle body is sleeved on the first end portion, the handle front end component is sleeved on the transition portion, and the handle tail end component is provided with an externally threaded post, the externally threaded post being inserted into the internally threaded connection hole and threadedly connected thereto.

[0007] Furthermore, the front end component and the rear end component of the handle are on the same axis as the handle body, and the outer diameters of the front end component and the rear end component are both larger than the outer diameter of the handle body.

[0008] Furthermore, the front end component of the handle is integrally formed with the handle body, the front end component of the handle is provided with a first sleeve hole that opens outward along the axial direction and matches the outer contour of the transition part, and the handle body is provided with a second sleeve hole that communicates with the first sleeve hole and is located on the same axis.

[0009] Furthermore, the handle end component is integrally formed with the handle body, and the handle end component is provided with a cavity that communicates with the second sleeve hole and is on the same axis. The external threaded post is integrally formed in the center of the cavity and extends towards the second sleeve hole.

[0010] Furthermore, the handle tail end component is separately disposed from the handle body. The external threaded post protrudes from the center of the side of the handle tail end component facing the handle body. When the external threaded post is inserted into the internal threaded connecting hole and threadedly connected with it, the inner end face of the handle tail end component abuts against the tail end of the handle body to prevent the handle body from coming off the first end.

[0011] Furthermore, the length of the external threaded post is less than the length of the internal threaded connecting hole.

[0012] Furthermore, two adjacent spring coils at the first end overlap axially to form the internal threaded connection hole on the inner circumference of the first end; two adjacent spring coils at the transition portion also overlap axially.

[0013] Furthermore, the distance between two adjacent spring coils in the main body is greater than the distance between two adjacent spring coils in the first end and / or the transition portion.

[0014] Furthermore, the spring tube also includes a second end located at the other end of the main body and having the same diameter as the main body. The second end is covered with a soft rubber sleeve, and the distance between two adjacent spring coils in the main body is greater than the distance between two adjacent spring coils in the second end.

[0015] Furthermore, the end part of the grip is also provided with a hanging rope that can be attached to the human hand during exercise.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Firstly, the spring tube of this utility model adopts an integrated helical spring structure design with different diameters, which is more reasonable and reliable than the existing technology. Specifically, due to the structural design of the transition section narrowing from the main body to the first end, on the one hand, to meet people's needs for fitness equipment with different diameter specifications, only a variety of main bodies with different diameter sizes need to be designed, while the first end can adopt the same diameter size. This allows for the design of a handle that matches the first end to be applicable to fitness equipment with various diameter specifications, thereby saving resources, reducing costs, and improving the convenience of product maintenance. On the other hand, the handle can be made more reasonably thick and thin due to the narrowing design of the first end, which helps to improve the grip comfort when using the fitness equipment and ensures that the grip is strong and the movement is not negatively affected.

[0018] Secondly, the outer diameters of the front and rear parts of the handle are relatively large, while the outer diameter of the main body of the handle is relatively small. This ensures that the main body of the handle will not slip from the hand when using the fitness equipment. Furthermore, the external threaded post on the rear part of the handle is threadedly connected to the internal threaded connection hole, preventing the main body of the handle from falling off the first end. The structure is simple and easy to assemble and disassemble. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0028] like Figures 1 to 8As shown, this embodiment provides a fitness device including a spring tube 1 and a gripping part 2. The spring tube 1 is a helical spring tube, which includes a main body 11 with a larger diameter, a first end portion 12 with a smaller diameter located at one end of the main body 11, and a transition portion 13 connected between the main body 11 and the first end portion 12, with the diameter gradually decreasing from the main body 11 towards the first end portion 12. An internally threaded connection hole 121 is formed on the inner circumference of the first end portion 12. The gripping part 2 includes a handle body 21, a handle front end component 22 located at the front end of the handle body 21, and a handle tail end component 23 located at the rear end of the handle body 21. The handle body 21 is sleeved on the first end portion 12, the handle front end component 22 is sleeved on the transition portion 13, and the handle tail end component 23 is provided with an externally threaded post 231, which is inserted into the internally threaded connection hole 121 and threadedly connected thereto. When the gripping part 21 is held and the fitness device is swung or rocked, the main body 11 can be driven to elastically vibrate along the swinging or rocking direction.

[0029] In this embodiment, the front end component 22 and the rear end component 23 of the handle are on the same axis as the handle body 21, and the outer diameters of the front end component 22 and the rear end component 23 are both larger than the outer diameter of the handle body 21.

[0030] In this embodiment, the front end component 22 of the handle is integrally formed with the handle body 21. The front end component 22 of the handle is provided with a first sleeve hole 221 that opens outward along the axial direction and matches the outer contour of the transition part 13. The handle body 21 is provided with a second sleeve hole 211 that communicates with the first sleeve hole 221 and is located on the same axis.

[0031] As in Example 1 Figure 1 , Figures 3 to 5 As shown, the handle end component 23 is integrally formed with the handle body 21, which will not fall off, making the structure more stable. The handle end component 23 is provided with a chamber 232 that communicates with the second sleeve hole 211 and is on the same axis. The external threaded post 231 is integrally formed in the center of the chamber 232 and extends to the second sleeve hole 211.

[0032] As described above, the installation operation principle of this embodiment 1 is as follows: the end of the first end 12 is sequentially inserted into the first sleeve hole 221 and the second sleeve hole 211, the front end part 22 of the handle is sleeved on the transition part 13 and is limited and stopped by it, the handle body 21 is sleeved on the first end 12, and the external threaded post 231 follows the handle tail end part 23 and is inserted forward into the internal threaded connection hole 121, and rotated to make it threadedly connected with the internal threaded connection hole 121, thereby realizing the installation of the spring tube 1 and the grip part 2.

[0033] This embodiment 2 is as follows Figures 6 to 8As shown, the handle tail end component 23 and the handle body 21 are separately disposed. The external thread post 231 protrudes from the center of the side of the handle tail end component 23 facing the handle body 21. When the external thread post 231 is inserted into the internal thread connection hole 121 and threadedly connected with it, the inner end face of the handle tail end component 23 abuts against the tail end of the handle body 21 to prevent the handle body 21 from coming off the first end 12.

[0034] As described above, the installation operation principle of this embodiment 2 is as follows: the end of the first end 12 is sequentially inserted into the first sleeve hole 221 and the second sleeve hole 211, the front end part 22 of the handle is sleeved on the transition part 13 and is limited and stopped by it, the handle body 21 is sleeved on the first end 12, the external threaded post 231 is inserted into the internal threaded connection hole 121 and threadedly connected to it, and the inner end face of the handle tail end part 23 abuts against the tail end of the handle body 21, thereby realizing the installation of the spring tube 1 and the grip part 2.

[0035] In this embodiment, the length of the external threaded post 231 is less than the length of the internal threaded connecting hole 121.

[0036] In this embodiment, two adjacent spring coils of the first end 12 overlap together axially, thereby forming an internal threaded connection hole 121 on the inner circumference of the first end 12; two adjacent spring coils of the transition part 13 also overlap together axially. This not only increases the structural strength of the two parts, but also increases the contact area between the gripping part 2 and the spring tube 1, making it less likely for the spring tube 1 and the gripping part 2 to fall off.

[0037] In this embodiment, the distance between two adjacent spring coils of the main body 11 is greater than the distance between two adjacent spring coils of the first end 12 and / or the transition part 13, so that the bending and inertia generated by the main body 11 are better when using the fitness equipment.

[0038] In this embodiment, the spring tube 1 also includes a second end 14 located at the other end of the main body 11 and having the same diameter as the main body 11. The second end 14 is covered with a soft rubber sleeve 3, which can protect the second end 14 from damage, thereby increasing its service life and improving the aesthetics of the fitness device. The distance between two adjacent spring coils in the main body 11 is greater than the distance between two adjacent spring coils in the second end 14.

[0039] In this embodiment, the handle end component 23 is also provided with a hanging rope 24 that can be hung on the human hand during exercise. During exercise, the hanging rope 24 can be hung on the wrist to prevent the fitness equipment from falling out of the hand and further protect the user's safety.

[0040] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
