Abstract
Description
Technical Field
[0001] The present application relates to the field of steppers, and in particular to a stepper with a position limiting adjustment function. Background Art
[0002] Conventional steppers include a base, and left and right pedals pivotally connected to the base. The left and right pedals alternately rotate relative to the base to achieve a fitness workout.

Furthermore, conventional steppers lack a limiter on the maximum range of pedal movement, making it easy for the bottom of the pedals to collide with the stepper frame during stepping.

The end of the adjustment screw 28 that passes through the waist-shaped hole is provided with a handle. The adjustment seat 37 has rollers at both ends. The rollers are slidably mounted on the first connecting rod 22 on both sides. The rollers are in rolling contact with the first connecting rod 22, and the side walls of the first connecting rod 22 slide against the side walls of the adjustment seat 37.

[0065] The connecting rod assembly includes a first connecting rod 22 , a second connecting rod 25 , a pivot member 23 , and a pedal seat 24 .
[0066] The first connecting rod 22 is tilted, with one end pivotally connected to the pivot member 23 and the other end pivotally connected to the fixed base 18. The second connecting rod 25 is tilted, with one end pivotally connected to the pivot member 23 and the other end hinged to the fixed base 18.

The step seat 24 is horizontally fixedly connected to one end of the pivot member 23, and the pedal 38 is fixedly connected to the step seat 24 via screws.
[0067] The damping member includes a hydraulic cylinder 21 ; a housing at one end of the hydraulic cylinder 21 is pivotally connected to a side wall of the limiting frame 29 , and a piston rod of the hydraulic cylinder 21 is pivotally connected to one end of the first connecting rod 22 .
[0068] The mounting seat 26 is fixedly connected to the side wall of the crossbar 11, the guide seat 34 is fixedly connected to the mounting seat 26, the guide rod 35 is fixedly connected to the guide seat 34, and the slider 36 is slidably connected to the guide seat 34. The guide rod 35 passes through the slider 36 and is in sliding contact with the slider 36. The second slider 32 is sleeved within the first slider 31 and is in sliding contact with the first slider 31. The ball head 33 is rollably mounted on the top wall of the slider 36 and is in ball connection with the second slider 32.
[0069] Working or installation process:
[0070] When the load of the hydraulic cylinder 21 needs to be adjusted, the handle on the adjusting screw 28 is turned, and the handle drives the adjusting screw 28 to rotate. The adjusting screw 28 is threadedly connected to the lifting seat 20, thereby driving the lifting seat 20 to move up and down. The lifting seat 20 drives the limit frame 29 to move up and down. The limit frame 29 moves up and down and drives one end of the hydraulic cylinder 21 to move up and down, thereby adjusting the tilt angle of the hydraulic cylinder 21. The change in the tilt angle of the hydraulic cylinder 21 causes the load of the hydraulic cylinder 21 to change.
[0071] According to the actual needs of the movement, the rubber cover 16 is rotated in the opposite direction, and the bolt 17 is disengaged from the threaded connection with the placement hole 14, and the rubber cover 16 stored on the cross bar 11 is removed from the cross bar 11 and the bolt 17 is aligned with one of the adjustment holes 15 and the rubber cover 16 is rotated. The rubber cover 16 drives the bolt 17 and is threadedly connected to the adjustment hole 15, and the rubber cover 16 is fixedly connected to the adjustment hole 15; and at this time, the rubber cover 16 is located below the movement trajectory of the pedal 38, and the upper end of the rubber cover 16 can support and limit the maximum movement amplitude of the pedal 38, thereby preventing the pedal 38 from directly hitting the step seat 24 or the pedal 38 on the adjustment hole 15 during the stepping movement.
[0072] The user steps on the two pedals 38 and performs a stepping motion. During the stepping motion, the fixed base 18 can rotate around the axis of the fixed guide post 27. In this process, the fixed base 18 drives the first connecting rod 22 to deflect around the axis of the fixed guide post 27. Since the side wall of the first connecting rod 22 slides against the side wall of the adjustment seat 37, the first connecting rod 22 presses against the adjustment seat 37 to deflect. The adjustment seat 37 drives the first slide bar 31 to move through the fixing member 30, causing the first slide bar 31 to drive the second slide bar 32 to rotate around the axis of the fixed guide post 27. The second slide bar 32 drives the slider 36 forward and backward along the extension direction of the guide rod 35 through the ball head 33. The first slide bar 31 and the second slide bar 32 swing around the ball head 33, thereby enabling the two pedals 38 to rotate in an "eight" shape.
[0073] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept.
