[0012] The utility model is beneficial in that:

[0013] 1. When the user pushes the abdominal wheel, the connecting shaft, the central shaft, and the bearing linkage end shaft rotate, and then the dial block rotates synchronously. When the dial block rotates, the rotating block is dialed. Under the dial block, the rotating block rotates to one side due to the action of the top rotating shaft. At the same time, the telescopic springs on both sides are stretched on one side and contracted on the other side. After the dial block passes the rotating block, the rotating block rebounds to its original state due to the action of the telescopic spring. In this way, the intelligent stepless adjustment of the travel distance can be assisted only by the control button, making the structural adjustment more convenient. The control button is a common one such as a thermos bottle cap pressing button. When pressed once, the bottom structure is snapped down to a fixed position. When pressed again, the bottom structure is driven to bounce up. In this way, when the control button bounces up, the rotating block bounces up. There is no contact surface between the bottom of the rotating block and the dial block, that is, the rotation of the end shaft is not restricted or affected. The user can exercise according to the training intensity and time during exercise. When the control button is pressed, the end shaft rotates one circle, and the dial block dials the rotating block, which can prompt the user the number of circles to rotate, and plays a certain role in limiting the number of rotating wheels when dialing;

[0014] 2. When the user uses the wheel body, by gripping the handle with fingers, the fingers will sink into the groove on the top of the anti-slip structure. Combined with the anti-slip protrusions, it can help the user to exercise and play an anti-slip role, preventing the user's palms from sweating during exercise and affecting efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figures 1 to 5 As shown, a stepless adjustment mechanism for the travel distance of an abdominal wheel includes a wheel body 1, a connecting shaft 2 is installed inside the wheel body 1, and a central shaft 3 is arranged in the middle position of the connecting shaft 2, bearings 4 are arranged at both ends of the connecting shaft 2, and the outer wall of the bearing 4 is connected to the end shaft 6, the outer wall of the end shaft 6 is installed with a shift block 7, and the outer side of the end shaft 6 is installed with a structural body 5.

[0025] A control button 501 is provided in the middle of the structural body 5, and a limit plate 502 is installed at the bottom of the control button 501, a rotating shaft 503 is installed in the middle of the limit plate 502, and a rotating block 505 is provided below the rotating shaft 503, and telescopic springs 504 are installed on both sides of the rotating block 505. When using the abdominal wheel for training, by pressing the control button 501, the control button 501 is pressed downward and fixed, so that the bottom of the rotating block 505 is in contact with the shift block 7. In this way, when the user uses the abdominal wheel, the rotating block 505 is shifted by the shift block 7, so as to achieve the purpose of assisting the intelligent stepless adjustment of the travel distance.

[0026] The rotating block 505 forms a rotating structure through the rotating shaft 503 and the limit plate 502, and the bottom of the rotating block 505 is inclined. When the user pushes the abdominal wheel, the connecting shaft 2, the central shaft 3, and the bearing 4 link the end shaft 6 to rotate, and then the shift block 7 rotates synchronously. When the shift block 7 rotates, the rotating block 505 is shifted. When the shift block 7 is shifted, the rotating block 505 rotates to one side due to the action of the top rotating shaft 503. At the same time, the telescopic springs 504 on both sides are stretched on one side and contracted on the other side. After the shift block 7 shifts the rotating block 505, the rotating block 505 rebounds to its original state due to the action of the telescopic springs 504. In this way, the intelligent stepless adjustment of the travel distance can be assisted only by the control button 501, making the structure adjustment more convenient.

[0027] The end shaft 6 is rotationally connected to the structural body 5, and the end shaft 6 and the shift block 7 are integrated. When the control button 501 is popped up, the rotation of the end shaft 6 is not restricted or affected. The user can exercise according to the training intensity and time. When the control button 501 is pressed, the shift block 7 shifts the rotating block 505 for each rotation of the end shaft 6, which can prompt the user the number of rotations and play a certain role in limiting the number of rotations when shifting.

[0028] Embodiment 2

[0029] See also Figures 1 to 3 As shown, a stepless adjustment mechanism for the travel distance of an abdominal wheel is provided, a handle 8 is installed on the right side of the outer wall of the structural body 5, and an anti-slip structure 9 is installed on the outer wall of the handle 8.

[0030] A groove 901 is reserved at the top of the anti-slip structure 9, and an anti-slip protrusion 902 is installed on the outer wall of the anti-slip structure 9. The anti-slip structure 9 is made of rubber material, and the anti-slip structure 9 and the anti-slip protrusion 902 are integrated. When the user uses the wheel body 1, by holding the handle 8 with fingers, the fingers are sunk into the groove 901 on the top of the anti-slip structure 9. Combined with the anti-slip protrusion 902, it can help the user to exercise and play an anti-slip role, preventing the user's palms from sweating during exercise and affecting efficiency.

[0031] Working principle: First, when the user pushes the abdominal wheel, the connecting shaft 2, the central shaft 3, and the bearing 4 link end shaft 6 rotate, and then the dial block 7 rotates synchronously. When the dial block 7 rotates, it dials the rotating block 505. Under the dialing of the dial block 7, the rotating block 505 rotates to one side due to the action of the top rotating shaft 503. At the same time, the telescopic springs 504 on both sides stretch on one side and contract on the other side. After the dial block 7 passes the rotating block 505, the rotating block 505 rebounds to its original state due to the action of the telescopic spring 504. In this way, the intelligent stepless adjustment of the travel distance can be assisted only by the control button 501, making the structure more accurate during adjustment. The control button 501 is a common button for pressing a thermos bottle cap. When the control button 501 is pressed once, the bottom structure is locked downward to a fixed position. When the control button 501 is pressed again, the bottom structure is driven to pop up. In this way, when the control button 501 pops up, the rotating block 505 pops up. There is no contact surface between the bottom of the rotating block 505 and the dial block 7, that is, the rotation of the end shaft 6 is not restricted or affected. The user can exercise according to the training intensity and time during exercise. When the control button 501 is pressed, the dial block 7 dials the rotating block 505 for each rotation of the end shaft 6, which can prompt the user the number of rotations. When the dial is turned, it plays a certain role in limiting the number of rotations.

[0032] Secondly, when the user uses the wheel body 1, by gripping the handle 8 with fingers, the fingers are sunk into the groove 901 at the top of the anti-slip structure 9. Combined with the anti-slip protrusion 902, it can help the user to exercise and play an anti-slip role, preventing the user's palms from sweating during exercise and affecting efficiency.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
