DETAILED DESCRIPTION

[0019] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0020] like Figure 1-5 As shown, this embodiment provides an elliptical machine pedal folding structure, including a first vertical tube 2, a first straight tube 3 and a limiting assembly 4.

[0021] The upper end of the first vertical tube 2 is connected with a rotating cylinder, which is used for rotationally connecting with the main frame 1 of the elliptical machine (not shown in the figure). Two first extension plates arranged at intervals are formed on the upper surface of the rotating cylinder, and a second extension plate extending downward is formed on the lower surface of the rotating cylinder. A rotating shaft 21 is formed at the lower end of the first vertical tube 2. A protrusion is formed on the upper side of the circumference of the rotating shaft 21, and a snap-in notch 211 is formed on the upper surface of the protrusion. A pedal seat is arranged at the end of the upper surface of the first straight tube 3. The lower surface of the first straight tube 3 has a mounting notch. The first straight tube 3 has a accommodating chamber in the first straight tube 3, which is connected with the extension port. The first straight tube 3 also has a threading channel. The end of the first straight tube 3 away from the pedal seat has a connecting seat 31, and the connecting seat 31 has a connecting notch. The connecting notch runs through the upper and lower surfaces and one side of the connecting seat 31. The rotating shaft 21 is located in the connecting notch, and the rotating shaft 21 is rotatably connected with the inner side wall of the connecting notch.

[0022] The position limiting assembly 4 is used to fix the position of the first straight tube 3 after folding. The position limiting assembly 4 includes a moving column 41 and a driving body. The first straight tube 3 has a protruding opening, which is located on the inner side wall of the connecting notch. The moving column 41 is located in the first straight tube 3. The driving body drives the moving column 41 to extend out of the protruding opening and cooperate with the inserted notch 211. The threading channel is connected to the accommodating chamber. The driving body includes a spring 43, a toggle wheel 44 and a traction line 42. The toggle wheel 44 is located in the installation notch. The toggle wheel 44 includes a wheel body and a toggle plate 441. The toggle plate 441 is connected to the circumference of the wheel body. The moving column 41 includes an extension section and a connecting section. The diameter of the extension section is greater than the diameter of the connecting section. The spring 43 is located in the accommodating chamber. The spring 43 is located between the extension section and the bottom wall of the accommodating chamber. One end of the traction line 42 is fixedly connected to the connecting section, and the other end of the traction line 42 is fixedly connected to the toggle wheel 44. The toggle wheel 44 is installed on the lower surface of the first straight tube 3.

[0023] Folding principle: first, push the toggle plate 441 to let the wheel pull backward, so that the movable column 41 retracts into the accommodating chamber, and the first straight tube 3 is turned upward until the movable column 41 is aligned with the notch 211, and the toggle plate 441 is released. Under the action of the spring 43, the movable column 41 is pushed out of the accommodating chamber, extends out from the extension port and is stuck in the notch 211, completing the folding.

[0024] The above shows and describes the basic principles and main features of the invention and the advantages of the invention. Those skilled in the art should understand that the invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the invention.
