[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0020] A curved rail stair climber includes a frame 4, a handrail 1, and foot pedals 10. A curved rail 5 is provided on the frame 4, a sliding structure 9 is provided on the curved rail 5, and a mounting seat 6 is provided on the curved rail 5. The sliding structure 9 is connected to the mounting seat 6, and the foot pedals 10 are mounted on the mounting seat 6. Through the sliding structure 9, when the exerciser steps on the foot pedals 10, the foot pedals 10 can slide alternately on the curved rail 5 to achieve the exercise effect.

[0021] A fixing hole is provided on the frame 4, and an adjusting rod 19 is threadedly connected to the fixing hole. A sleeve 23 is inserted into the frame 4, and a positioning groove 17 is provided on the sleeve 23. An elastic piece 21 is fixedly connected to the positioning groove 17, and a snap-fit ​​block 16 is fixedly connected to the elastic piece 21. A snap-fit ​​hole 14 is provided on the frame 4, and the snap-fit ​​block 16 snaps into the snap-fit ​​hole 14. With the snap-fit ​​block 16 and the snap-fit ​​hole 14, the sleeve 23 is fixedly installed on the frame 4. The snap-fit ​​block 16 is provided with a beveled surface. The beveled surface and the elastic piece 21 facilitate the insertion of the sleeve 23 and the snap-fit ​​block 16 into the frame 4, and at the same time facilitate the snap-fit ​​block 16 snaps into the snap-fit ​​hole 14.

[0022] One end of the handrail 1 is inserted into the sleeve 23. The handrail 1 has multiple adjustment holes 15. The positioning groove 17 is between the fixing hole and the adjustment hole 15. The adjustment rod 19 passes through the limiting groove 2 and is threaded into the adjustment hole 15. When adjusting the height of the handrail 1, remove the adjustment rod 19 from the adjustment hole 15 and the fixing hole, pull the handrail 1 up and down to align the adjustment hole 15 of the handrail 1 with the fixing hole at the appropriate height, and then screw the adjustment rod 19 into the fixing hole and the adjustment hole 15 respectively. The handrail 1 is then re-fixed to the frame 4, so that the height of the handrail 1 can be quickly and easily adjusted.

[0023] The sleeve 23 eliminates the gap between the handrail 1 and the frame 4, increases the stability of the handrail in the frame, and makes the handrail 1 less prone to shaking in the frame 4; the positioning groove 17 allows the adjusting rod 19 to be easily threaded through the positioning groove 17 and connected to the adjusting hole 15.

[0024] A threaded ring 20 is fixedly connected to the frame 4, and a retaining ring 18 is fixedly connected to the adjusting rod 19. The outer side of the adjusting rod 19 is threadedly connected to the inner side of the threaded ring 20. The threaded ring 20 and the retaining hole make the connection between the adjusting rod 19 and the frame 4 tighter. An auxiliary plate 3 is fixedly connected to the adjusting rod 19, and the retaining ring 18 is located between the adjusting rod 19 and the auxiliary plate 3. The auxiliary plate 3 allows for better force application when tightening or loosening the threads of the adjusting rod 19.

[0025] The foot pedal 10 is fixedly connected to a mounting plate 8. One end of the mounting plate 8 is rotatably mounted on a mounting base 6. The mounting plate 8 has a positioning hole 13. A positioning cylinder is fixedly mounted on the mounting base 6, and the positioning hole 13 communicates with the positioning cylinder. A positioning rod 7 is inserted into the positioning hole 13 and is inserted into the positioning cylinder. Through the positioning rod 7 and the positioning cylinder, the foot pedal 10 is positioned and mounted on the mounting base 6.

[0026] Multiple positioning holes 13 are provided on the mounting plate 8. The angle of the foot pedal 10 during exercise can be adjusted by the multiple positioning holes 13. With the setting of the curved rail 5, when the exerciser steps on the foot pedal 10 to perform alternating rising stepping exercises, the curved rail 5 makes the movement trajectory of the foot pedal 10 closer to the actual movement trajectory of the leg when stepping.

[0027] A fixing plate 12 is fixedly installed on the frame 4. Two fixing plates 12 are mirror images of each other on the frame 4. One end of the curved rail 5 is rotatably mounted on the fixing plate 12. A fixing rod 11 is threadedly connected to the fixing plate 12. The fixing rod 11 is threadedly connected to the curved rail 5. Through the setting of the fixing rod 11, the curved rail 5 is positioned and installed on the frame 4. At the same time, when the stair machine is not in use, the fixing rod 11 can be removed from the curved rail 5 and the fixing plate 12, and the curved rail 5 can be rotated towards the frame 4. The curved rail 5 can be folded on the frame 4 for easy storage.

[0028] The implementation principle of this embodiment is as follows: When adjusting the height of the handrail 1, the adjusting rod 19 is unscrewed from the frame 4 and the handrail 1 through the auxiliary plate 3. At this time, the handrail 1 can move up and down on the frame 4. Pull the handrail 1 up or press it down so that the appropriate adjusting hole 15 on the handrail 1 is aligned with the fixing hole. Then, screw the adjusting rod 19 into the fixing hole and the adjusting hole 15 aligned with the fixing hole respectively. The handrail 1 is repositioned and installed on the frame 4. The height adjustment of the handrail 1 is completed, and the height of the stair machine handrail 1 can be adjusted.
