[0037] The implementation principle of this utility model of a foldable portable magnetic resistance stair climber is as follows:

[0038] Storage: Tighten the adjusting bolt 21 to separate it from the connecting block 121. Pull the adjusting bolt 21 out from the adjusting hole 221 and the insertion hole. Rotate the armrest 2 to be flush with the frame 1. Tighten the adjusting bolt 21 to fix the armrest 2. Then tighten the fixing bolt 31 to separate it from the connecting frame 13. Rotate the support leg 3 to be flush with the back of the frame 1. Then pull out the fixing pin 41 to separate the foot pedal 4 from the movable frame 45. Then press the foot pedal 4 down to be flush with the frame 1. Then insert the fixing pin 41 into the corresponding through hole 44 to fix it to the movable frame 45, so that the foot pedal 4 is flush with the frame 1. This achieves the function of quick folding, which is convenient for storage and movement and occupies little space.

[0039] Unfold: First, rotate the support leg 3 to separate it from the frame 1. The support leg 3 rotates on the connecting frame 13. Then, tighten the fixing bolt 31 to install it on the connecting frame 13 to fix the support leg 3. Then, pull out the fixing pin 41 to separate the foot pedal 4 from the movable frame 45. Then, lift the foot pedal 4 to separate it from the frame 1. Then, insert the fixing pin 41 into the corresponding through hole 44 to fix it to the movable frame 45, so that the foot pedal 4 is flush with the ground. Then, tighten the adjusting bolt 21 and pull it out. Rotate the handrail 2 to move it to a suitable position. Insert the adjusting bolt 21 into the corresponding adjusting hole 221 from the insertion hole and tighten it to connect and fix the handrail 2 with the connecting block 121.

[0040] Usage: Place both feet on foot pedals 4 and press down firmly to move the movable frame 45 downwards. This causes the slider 42 and pulley 43 to move downwards. The slider 42 moves the fixed synchronous belt 51, and the pulley 43 moves along the slide rail 11. The synchronous belt 51 simultaneously drives the drive wheel 52 and tension wheel 54 to rotate, which in turn moves the other foot pedal 4 upwards. The drive wheel 52 rotates while driving the magnetic control wheel 53 to rotate. After pressing down to the bottom, press down on the other foot pedal 4. Repeat the above steps to perform a stair-climbing motion. When the magnetic control wheel 53 increases the resistance, the user needs to increase the downward pressing force to increase the intensity of the exercise.

[0041] It should be noted that the spring 63 pushes the movable rod 62 to pull the locking block 61, which in turn pulls the tension wheel 54 to tighten the synchronous belt 51, ensuring the stability of the synchronous belt 51 when it moves up and down.

[0042] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
