DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1 As shown, this embodiment discloses a pedal height adjustment mechanism, including a pedal assembly and a track assembly 3, wherein the track assembly 3 is mounted on a main frame 1, and the slope of the main frame 1 is adjustable. Figure 3As shown, it includes a pedal lower connecting frame assembly weld 4, a pedal assembly weld 5, and a pedal middle connecting plate assembly weld 6. One end of the pedal lower connecting frame assembly weld 4 is rotatably connected to the pedal assembly weld 5 through a long rod 7, and the other end of the pedal lower connecting frame assembly weld 4 is rotatably connected to the pedal middle connecting plate assembly weld 6 through a short rod 8. The pedal middle connecting plate assembly weld 6 is rotatably connected to the pedal assembly weld 5 through the short rod 8. Multiple groups of pedal lower connecting frame assembly welds, pedal assembly welds, and pedal middle connecting plate assembly welds are connected end to end to form a closed-loop structure. Small PU wheels 2 are installed on both sides of the pedal lower connecting frame assembly weld, and the small PU wheel 2 rolls along the track assembly weld 3. Small PU wheels 10 are provided at both ends of the long rod, and the small PU wheels 10 roll along the main frame.

[0019] like Figure 5 As shown, the pedal lower connecting frame is welded to include a triangular connecting member 15 and a pedal 16. Two triangular connecting members are provided, and the two triangular connecting members are respectively fixedly connected to the two ends of the pedal. The two vertices of the triangular connecting member are respectively provided with through holes for connecting the short rod and the long rod.

[0020] like Figure 4 As shown, the track assembly welding includes a left track 11, a right track 12, a connecting rod 13, and a connecting rod 2 14. The left track and the right track are connected by the connecting rod 1, and both ends of the connecting rod 2 pass through the left track and the right track and are connected to the main frame.

[0021] This embodiment also discloses a step training device, such as Figure 2 As shown, it includes the above-mentioned pedal height adjustment mechanism, which is installed on the main frame. A base frame is arranged at the bottom of the main frame. One end of the main frame is rotatably connected to the base frame. A lifting mechanism for changing the slope of the main frame is arranged between the angle formed by the main frame and the base frame.

[0022] When the utility model is working, the lifting and lowering of the main frame is controlled by the lifting mechanism to change the slope. When the slope of the main frame 1 rises, the track assembly weld 3 in the main frame 1 will lift up one end of the triangular pedal lower connecting frame assembly weld 4 fixed with the small PU wheel 2, so that the pedal lower connecting frame assembly weld 4 rotates clockwise with the end connected to the long rod 7 as the center, and then the end of the pedal lower connecting frame assembly weld 4 connected to the short rod 8 drives the pedal middle connecting plate assembly weld 6 to flip toward the outside of the pedal assembly 9, and then the pedal assembly weld 5 is lifted upward to achieve the function of increasing the step height. On the contrary, when the slope decreases, the track assembly weld 3 in the main frame 1 will lower the end of the triangular pedal lower connecting frame assembly weld 4 fixed with the small PU wheel 2, so that the pedal lower connecting frame assembly weld 4 will rotate counterclockwise around the end axially connected to the long rod 7, and then the end of the pedal lower connecting frame assembly weld 4 axially connected to the short rod 8 will drive the pedal middle connecting plate assembly weld 6 to flip toward the inside of the pedal assembly 9, and then the pedal assembly weld 5 will be lowered to achieve the function of lowering the step height.

[0023] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
