Description

Technical Field

[0001] The utility model relates to the technical field of fitness, in particular to an abdominal fitness wheel with an abdominal fitness function. Background Art

[0002] Nowadays, more and more people are paying attention to maintaining their figure, especially men, who like to exercise their abdominal muscles. Ab wheels are small pushers that can exercise muscles, joints, and reduce weight. Ab wheels are particularly popular for exercising abdominal muscles. Ab wheels are mainly used to exercise the abdomen, waist, hips, and arms. They require a simple space and are easy to use.

[0003] The width of the existing abdominal wheel in contact with the ground is fixed. When the width of the abdominal wheel in contact with the ground is narrow, the walking stability of the abdominal wheel is poor, which is not conducive to exercise for beginners and can only be mastered by experienced exercisers. When the width of the abdominal wheel in contact with the ground is wide, the walking stability of the abdominal wheel is very good, but it is not conducive to exercisers with higher requirements.

[0004] For example, an abdominal wheel disclosed in Chinese patent CN216456735U can stably be set in the middle of the support shaft without affecting the rotation of the two rollers through the mutual restriction of the handle, two rollers and two spacers, thereby increasing the stability of the product. The outer peripheral surface of the handle is provided with an anti-slip cover, which increases the comfort of holding the product and is aesthetically pleasing.

[0005] However, the length of the handle of the abdominal wheel cannot be changed, so it is not suitable for different fitness people.

[0006] For this reason, we urgently need to provide an adjustable abdominal wheel with abdominal fitness function. Utility Model Content

[0007] The purpose of the present invention is to provide an abdominal fitness wheel with an abdominal fitness function, so as to solve the problem in the above-mentioned background technology that the handle length of the abdominal fitness wheel cannot be changed and is therefore not suitable for use by different fitness people.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an abdominal wheel with abdominal fitness function, comprising a threaded rod and a roller, the roller being connected to the outer end of the threaded rod, the outer end of the threaded rod being connected to an adjustment mechanism, the adjustment mechanism comprising a length adjustment unit and a width adjustment unit, the length adjustment unit being arranged at the left and right ends of the threaded rod, and the width adjustment unit being arranged at the outer end of the threaded rod.

[0009] The length adjustment unit includes a cylinder, an adjustment rod, a spring, a plug rod and a grip. The cylinder is symmetrically and fixedly connected to the left and right sides of the threaded rod. The adjustment rod is slidably connected to the inside of the cylinder. The spring is connected to the inside of the adjustment rod. The plug rod is fixedly connected to the upper end of the spring. The grip is fixedly connected to the end of the adjustment rod away from the cylinder.

[0010] Further improvement lies in that a circular groove starts above one end of the adjustment rod close to the threaded rod inside. The lower end of the spring is fixedly connected to the inner bottom end of the circular groove. The outer side of the plug rod is slidably connected to the inside of the circular groove. Thus, when the spring bounces, it can drive the plug rod to slide along the inside of the circular groove, thereby playing a role in limiting the movement of the plug rod.

[0011] Further improvement lies in that jacks are equidistantly arranged at the upper end inside the cylinder. The outer side of the upper end of the plug rod is inserted into the inside of the jacks. Thus, after sliding the adjustment rod to different positions inside the cylinder, and then pushing the plug rod upward by the spring rebound, when the upper end of the plug rod is moved upward to the jacks at the corresponding positions, the adjustment rod can be re-fixed after moving, so that the overall length of the cylinder and the adjustment rod changes, and the position of the grip changes, thereby facilitating different fitness enthusiasts to use.

[0012] Further improvement lies in that the width adjustment unit includes a circular tube and a limiting ring. The circular tube is connected to the outside of the threaded rod. The limiting rings are fixedly connected to the left and right ends outside the circular tube.

[0013] Further improvement lies in that a rotating hole is provided at the middle position inside the roller. The outside of the circular tube is rotatably connected to the inside of the rotating hole. The adjacent sides of the limiting rings at the left and right ends outside the circular tube are slidably connected to the middle positions on the left and right sides of the roller. Thus, when the roller rotates, it can only rotate between the limiting rings outside the circular tube, playing a role in limiting the rotation of the roller.

[0014] Further improvement lies in that internal threads are provided inside the circular tube. The outside of the threaded rod is threadedly connected to the inside of the circular tube. Thus, when the circular tube is rotated outside the threaded rod, the circular tube can move relative to the threaded rod, so that the distance between the two rollers at the outer end of the threaded rod changes, the width of the rollers at the outer end of the threaded rod changes, and the rolling of the abdominal wheel becomes more stable.

[0015] Further improvement lies in that an anti-slip pad is fixedly connected to the outside of the grip. Thus, when a fitness enthusiast uses the abdominal wheel, it can be grasped more firmly.

[0016] In summary, the present application discloses an abdominal wheel with an abdominal fitness function.

[0017] After the adjusting rod is slid to different positions inside the cylinder, the spring rebounds to push the plug rod upward. After the upper end of the plug rod is moved upward to the jack at the corresponding position, the adjusting rod can be fixed again after moving, so that the overall length of the cylinder and the adjusting rod is changed, and the position of the grip is changed, thus facilitating different fitness enthusiasts to use.

[0018] Furthermore, by rotating the round tube outside the threaded rod, the round tube can move relative to the threaded rod, so that the distance between the two rollers at the outer end of the threaded rod is changed, the width of the rollers at the outer end of the threaded rod is changed, and the rolling of the abdominal wheel is more stable.

An adjusting mechanism is connected to the outer end of the threaded rod 1. The adjusting mechanism includes a length adjusting unit and a width adjusting unit. The length adjusting unit is arranged at the left and right ends of the threaded rod 1, and the width adjusting unit is arranged at the outer end of the threaded rod 1.

[0027] The length adjustment unit includes a cylinder 301, an adjustment rod 302, a spring 303, a plug rod 304 and a grip 305. The cylinder 301 is symmetrically and fixedly connected to the left and right sides of the threaded rod 1. The adjustment rod 302 is slidably connected to the inside of the cylinder 301. The spring 303 is connected to the inside of the adjustment rod 302. The plug rod 304 is fixedly connected to the upper end of the spring 303. The grip 305 is fixedly connected to the end of the adjustment rod 302 away from the cylinder 301. There is a circular groove above the inner end of the adjustment rod 302 close to the threaded rod 1. The lower end of the spring 303 is fixedly connected to the inner bottom end of the circular groove. The outer side of the plug rod 304 is slidably connected to the inner side of the circular groove. Thus, when the spring 303 bounces, it can drive the plug rod 304 to slide along the inner side of the circular groove, thereby playing a role in limiting the movement of the plug rod 304.

[0028] The upper end inside the cylinder 301 is provided with insertion holes at equal distances. The outer side of the upper end of the plug rod 304 is inserted into the inner side of the insertion holes. Thus, after sliding the adjustment rod 302 to different positions inside the cylinder 301, and then pushing the plug rod 304 upward by the rebound of the spring 303, when the upper end of the plug rod 304 is moved upward to the corresponding insertion hole, the adjustment rod 302 can be re-fixed after moving, so that the overall length of the cylinder 301 and the adjustment rod 302 changes, and the position of the grip 305 changes, thus facilitating different fitness enthusiasts to use. Embodiment

[0029] On the basis of Embodiment 1: The width adjustment unit includes a circular tube 401 and a limiting ring 402. The circular tube 401 is connected to the outside of the threaded rod 1.

The adjacent sides of the limiting rings 402 at the left and right ends of the outside of the circular tube 401 are slidably connected to the middle positions on the left and right sides of the roller 2. Thus, when the roller 2 rotates, it can only rotate between the limiting rings 402 on the outside of the circular tube 401, playing a role in limiting the rotation of the roller 2.

[0030] Internal threads are provided inside the circular tube 401. The outside of the threaded rod 1 is threadedly connected to the inside of the circular tube 401. Thus, when the circular tube 401 is rotated on the outside of the threaded rod 1, the circular tube 401 can move relative to the threaded rod 1, so that the distance between the two rollers 2 at the outer end of the threaded rod 1 changes, the width of the rollers 2 at the outer end of the threaded rod 1 changes, and the rolling of the abdominal wheel is more stable. Embodiment

[0031] On the basis of Embodiment 1: The outside of the grip 305 is fixedly connected with an anti-slip pad. Thus, when a fitness enthusiast uses the abdominal wheel, it can be grasped more firmly.

[0032] Working principle: Before using the ab wheel, first rotate the circular tube 401 outside the threaded rod 1 until the distance between the rollers 2 is adjusted to the required value.
