[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See Figures 1-7 A treadmill roller structure includes a roller body 1, and the outer wall of the roller body 1 has a plurality of grooves 2 circumferentially provided to prevent the running belt from deviating laterally.

[0025] In this embodiment, the roller body 1 includes a middle section 11 and an outer section 12 arranged at the left and right ends of the middle section 11. The left and right ends of the middle section 11 are respectively provided with groove groups, and each groove group includes multiple grooves 2. As one embodiment, the multiple grooves 2 of each groove group are arranged evenly in sequence.

[0026] The running belt is wound around the middle section at point 11, and the groove groups on the left and right sides correspond to the left and right ends of the running belt, respectively, to restrict the running belt in the left and right directions and prevent the running belt from deviating to the side.

[0027] In one implementation, a groove 2 is arranged in more than half of the middle section 11, such as in two-thirds of the section, while a smooth part is left in the middle to ensure that the normal operation of the running belt is not affected.

[0028] In this embodiment, the outer section 12 of the roller body 1 includes a tapered section 121. The outer diameter of the tapered section 121 gradually decreases from the inside to the outside, that is, the outer diameter of the tapered section 121 gradually decreases from the point where it connects with the middle section 11 to its outer end.

[0029] The design of the conical section 121 can also prevent the running belt from deviating to the side. Adding this design on the basis of setting the groove 2 can further improve the above-mentioned effect.

[0030] In this embodiment, the outer section 12 also includes two outer end portions 122 on the left and right. The outer section portions 122 are arranged on the outside of the conical section 121. The roller body 1 can be an integrally formed component, or specifically a hollow tube.

[0031] The outer end portion 122 is respectively assembled onto the corresponding mounting part 3, and the mounting part 3 is installed on the treadmill. The two mounting parts 3 on the left and right sides enable the roller body 1 to be positioned on the treadmill.

[0032] Specifically, a connecting shaft 41, such as a bolt, can be threaded through the mounting component 3. The connecting shaft 41 is then mounted on a metal component 42, such as a U-shaped metal component. The metal component 42 is then fixed to the treadmill frame 43, such as by welding or by fasteners.

[0033] The mounting component 3 includes a receiving cavity 31 for accommodating the outer end portion 122, and a bearing 5 is assembled between the inner wall of the receiving cavity 31 and the outer end portion 122. Furthermore, a retaining ring groove 123 is provided on the outer end portion 122, and a retaining ring 6 for limiting the bearing 5 is disposed on the retaining ring groove 123.

[0034] In this embodiment, the accommodating cavity 31 of the mounting component 3 is divided into two interconnected parts. The outer part 311 is adapted to the bearing 5, including its shape and size. The inner part 312 is used to accommodate the portion of the outer end part 122 that extends beyond the bearing 5, including a portion with a retaining spring groove 123, specifically as follows: Figure 7 As shown.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
