[0052] As Figures 2 to 3 The present application provides an elliptical machine pedal double roller adaptive structure, which comprises a pedal frame 1, a roller 2 installed on the lower side of one end of the pedal frame 1, and a connecting assembly 3 arranged between the pedal frame 1 and the roller 2 for realizing the connection of the roller 2 and the pedal frame 1.

[0053] Specifically, the connecting assembly 3 comprises two parallel connecting plates 31 fixed on the pedal frame 1, a roller frame 32 rotatably connected between the two connecting plates 31, and a limiting piece 33 for limiting the rotation angle of the roller frame 32 relative to the connecting plate 31, and the roller 2 is rotatably connected to the roller frame 32. During installation, when one of the rollers 2 is in a suspended state and not in contact with the track, the roller frame 32 can be operated to rotate relative to the connecting plate 31 to adjust the positions of the two rollers 2, so that both rollers 2 are located on the track, thereby reducing the requirement for installation accuracy. The limiting piece 33 can limit the rotation angle of the roller frame 32 to ensure the accuracy of the overall installation position and realize small-range error tolerance.

[0054] In some embodiments of the present application, the roller frame 32 comprises a roller plate 321 for mounting the roller 2 and a mounting cylinder 322 fixed at one end of the roller plate 321, and the mounting cylinder 322 is used to connect with the connecting plate 31 to realize the rotary connection with the connecting plate 31.

[0055] Specifically, the mounting shaft 323 is arranged between the two connecting plates 31, is arranged in the mounting cylinder 322 and is rotationally connected with the mounting cylinder 322, so that the roller frame 32 can be rotationally connected with the connecting plates 31 while being mounted between the two connecting plates 31. The mounting shaft 323 can be specifically a mounting bolt 3231 and a nut 3232 threaded on one end of the mounting bolt 3231. When mounting, the mounting bolt 3231 is directly arranged from one connecting plate 31 to the other connecting plate 31, passes through the mounting cylinder 322 and is finally screwed on the end of the mounting bolt 3231 that is arranged outside the connecting plate 31, so that the two connecting plates 31 and the mounting cylinder 322 between the two connecting plates 31 are fixed between the bolt head of the mounting bolt 3231 and the nut 3232, the roller frame 32 and the connecting plates 31 are fixed, and the roller 2 and the foot support 1 are mounted.

[0056] In some embodiments of the utility model, in order to ensure that the mounting cylinder 322 can smoothly slide between the two connecting plates 31, the first bearing 324 is arranged between the mounting shaft 323 and each connecting plate 31, and the second bearing 325 is arranged between the mounting shaft 323 and the mounting cylinder 322, so that the rotation smoothness of the mounting cylinder 322 is ensured by the first bearing 324 and the second bearing 325.

[0057] In some embodiments of the utility model, the limiting piece 33 includes a limiting plate 331 fixed between the two connecting plates 31, and a limiting space 333 for embedding the limiting plate 331 is arranged on the side wall of the mounting cylinder 322.

[0058] In some embodiments of the utility model, specifically, the limiting space 333 can be a groove arranged on the side wall of the mounting cylinder 322, or two limiting blocks 332 fixed on the side wall of the mounting cylinder 322, and the two limiting blocks 332 are arranged at intervals, so that the limiting space 333 is formed between the two limiting blocks 332.

[0059] The utility model is described by taking the example that the two limiting blocks 332 are fixed on the side wall of the mounting cylinder 322, and the width of the limiting space 333 is greater than the thickness of the limiting plate 331, so that when the roller frame 32 is mounted between the two connecting plates 31, the limiting plate 331 is also arranged in the limiting space 333, and because the width of the limiting space 333 is greater than the thickness of the limiting plate 331, the roller frame 32 can rotate within a certain range relative to the two connecting plates 31, the installation position of the roller 2 is adjusted, the requirement for the installation precision of the roller 2 is reduced, and the fault tolerance is greatly improved.

In use, the rollers 2 are directly sleeved on the mounting rods 326, and the limiting pads 327 are sleeved on the mounting rods 326, so that the limiting plates 331 are located at the sides of the rollers 2 away from the roller plate 321, thereby fixing the positions of the rollers 2 on the mounting rods 326 through the limiting plates 331 and the roller plate 321; finally, the fixing bolts 328 are screwed at the ends of the mounting rods 326 away from the roller plate 321. The bolt head of the fixing bolt 328 is larger than the diameter of the mounting rod 326, so that when the fixing bolt 328 is screwed at the end of the mounting rod 326, the position of the limiting plate 331 on the mounting rod 326 is fixed through the fixing bolt 328, and the mounting and fixing of the roller 2 are realized.

[0061] The footrest flat plate 4 is fixedly connected to the upper side of the footrest frame 1, is located at one end of the footrest frame 1 where the rollers 2 are mounted, and is directly stepped on by a user in use, thereby driving the footrest flat plate 4 to move forward and backward, so that the rollers 2 slide on the track and exercise is realized.

[0062] The utility model also provides an elliptical machine, which comprises the above-mentioned elliptical machine footrest double-roller self-adapting structure.

[0063] The rotation connection design between the roller frame and the connecting plate, in cooperation with the use of the limiting piece, enables the roller frame to freely rotate within a certain range, ensures that the double rollers can keep good contact with the track at different positions, simplifies the installation and debugging process of the elliptical machine, improves the overall performance and reliability of the elliptical machine, and reduces the installation and maintenance costs.
