[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1: In this embodiment, as Figure 1 The adjustable limb coordination training device shown includes a training platform 1 with an offset block 2 above it; a gap adjuster installed on the lower surface of the offset block 2, on which two foot pedals 3 are mounted, and the gap adjuster is used to adjust the distance between the two foot pedals 3; a linkage adjuster installed at one end of the offset block 2, and the linkage adjuster is used to rotate the offset block 2; and a main adjuster installed on one side of the training platform 1, and the main adjuster is used to adjust the rotation angle of the training platform 1.

[0030] In this embodiment, the exerciser places both feet on two footrests 3. When the main adjustment component allows the exercise platform 1 to rotate vertically for adjustment, the linkage adjustment component allows the offset block 2 to rotate horizontally for adjustment. In this way, the offset block 2 drives the gap adjustment component, which in turn drives the two footrests 3 to rotate horizontally for adjustment. At the same time, the gap between the two footrests 3 can also be adjusted for adjustment. This multi-dimensional coordinated exercise is more effective, and the leg limbs are thoroughly exercised.

[0031] Example 2: In this embodiment, as Figure 2 - Figure 3 As shown, the gap adjustment component includes: a linkage block 4, which is fixed to the lower surface of the offset block 2, and a support frame 5 is fixedly installed at one end of the linkage block 4; Guide rod 6 is fixedly connected to the inner wall of support frame 5. Two sliding sleeve blocks 7 are slidably installed on the outer wall of guide rod 6, and the sliding sleeve blocks 7 are fixedly connected to the footrest 3. Both sliding sleeve blocks 7 are slidably connected to support frame 5. Support block 8 is fixed to one side of footrest 3. An elastic band 9 is fixedly connected between the two support blocks 8, and the elastic band 9 is used to provide elastic force to the two support blocks 8. The two sliding sleeve blocks 7 are symmetrically arranged about the middle of support frame 5, and both sliding sleeve blocks 7 are slidably connected to support frame 5. Both footrests 3 are slidably connected to support frame 5, and the two support blocks 8 are symmetrically arranged about the elastic band 9.

[0032] The principle of this embodiment is that when both feet are placed between the two footrests 3, the feet move away from each other and exert force, thereby increasing the distance between the two footrests 3 and the two support blocks 8. The two support blocks 8 pull the elastic band 9 to stretch elastically. At the same time, the two footrests 3 increase the distance between the two sliding blocks 7. The two sliding blocks 7 slide along the outer wall of the guide rod 6 and along the inner wall of the support frame 5. The two footrests 3 can adjust the distance between the legs for exercise.

[0033] Example 3: In this embodiment, as Figure 4 - Figure 5As shown, the linkage adjustment component includes: a collar 10, fixed to one end of the offset block 2, with a positioning shaft 11 installed on the inner wall of the collar 10, the bottom end of the positioning shaft 11 being fixedly connected to the exercise table 1, the positioning shaft 11 being used to position the rotation of the collar 10, and a limiting ring 12 provided on the upper surface of the collar 10, the limiting ring 12 being fixedly connected to the positioning shaft 11, and the limiting ring 12 being rotatably connected to the collar 10; an arc-shaped plate 13, fixed to the outer wall of the offset block 2, with a connecting block 14 fixed to one side of the outer wall of the arc-shaped plate 13. A first offset elastic band 15 is installed on one side of the connecting block 14. A support bar 16 is fixedly provided at one end of the first offset elastic band 15. The support bar 16 is fixedly connected to the exercise table 1, and the first offset elastic band 15 is used to provide elastic force to the connecting block 14. Both the connecting block 14 and the support bar 16 are fixedly connected to the first offset elastic band 15. Multiple balls 19 are rolled and installed on the lower surface of the arc plate 13. A bushing 18 is installed on the outer wall of the balls 19. A grooved ring 17 is fixed at the bottom end of the bushing 18 and is fixedly connected to the exercise table 1. The upper surface of the connecting block 14 is parallel to the upper surface of the first offset elastic band 15, and the vertical cross-sectional shape of the support bar 16 is L-shaped. The cross-sectional shape of the arc plate 13 is arc-shaped, and the multiple balls 19 are arranged in a circular distribution.

[0034] The operating principle of this embodiment is as follows: When both feet step on the footrest 3 and rotate laterally, the footrest 3 will drive the sliding block 7 to rotate laterally. The sliding block 7 will drive the guide rod 6 to rotate laterally. The guide rod 6 will drive the support frame 5 to rotate laterally. The support frame 5 will drive the linkage block 4 to rotate laterally. The linkage block 4 will drive the offset block 2 to rotate laterally. The offset block 2 will drive the collar 10 to rotate laterally. The collar 10 rotates laterally along the outer wall of the positioning shaft 11. At the same time, the exercise table 1 supports the positioning shaft 11, the positioning shaft 11 supports the limiting ring 12, and the limiting ring 12 limits the collar 10. The collar 10 rotates on the lower surface of the limiting ring 12. At the same time, the offset block 2 will drive the arc plate 13 to rotate laterally, and the arc plate 13 will drive the connecting block 1... 4. When rotating laterally, the connecting block 14 pulls the first offset elastic band 15, while the exercise platform 1 supports the support bar 16, which in turn supports the first offset elastic band 15. Thus, the first offset elastic band 15 is pulled by the connecting block 14, providing elastic force to the connecting block 14. At the same time, the arc plate 13 slides on the outer wall of multiple balls 19, and the exercise platform 1 supports the groove ring 17, which in turn supports the bushing 18. The bushing 18 positions the balls 19, so the collar 10 drives the balls 19 to roll on the inner wall of the bushing 18. In this way, the two pedals 3 can achieve lateral rotation operation, allowing the two legs to adjust the distance between the two pedals 3 while exercising, thus achieving lateral rotation adjustment.

[0035] Example 4: In this embodiment, as Figure 6 - Figure 8As shown, the main adjustment component includes: a sleeve 20, fixedly connected to one side of the exercise table 1, with an arc-shaped block 21 fixed to one side of the outer wall of the sleeve 20 near its bottom end; a guide rail 22 is installed on the inner wall of the arc-shaped block 21 to guide the arc-shaped block 21 to slide; an outer frame 23 is installed on the outer wall of the arc-shaped block 21 to guide the arc-shaped block 21 to slide, with a reinforcing strip 24 fixed to one side of the outer frame 23; and a second offset elastic band 25, fixedly connected to the upper surface of the arc-shaped block 21, with both sides of the second offset elastic band 25 having a sliding... The device includes two movable limit strips 26, both of which are fixedly connected to the reinforcing strip 24. A positioning sleeve 27 is fixed to the top of the second offset elastic band 25. A support shaft 28 is installed on the inner wall of the positioning sleeve 27, and the support shaft 28 is fixedly connected to the reinforcing strip 24. A limit shaft 29 is installed on the inner wall of the sleeve 20, and the limit shaft 29 is rotatably connected to the sleeve 20. A handheld bracket 30 is fixed to one end of the limit shaft 29. The outer frame 23 is fixedly connected to the reinforcing strip 24. The two limit strips 26 are symmetrically arranged about the second offset elastic band 25. The vertical cross-sectional shape of the limit strip 26 is L-shaped, and the reinforcing strip 24 is inclined.

[0036] The operating principle of this embodiment is as follows: the handheld frame 30 is fixedly installed by inserting bolts into the holes at the bottom of the handheld frame 30. The handheld frame 30 supports the limiting shaft 29, which is used to position the rotation of the sleeve 20. When both feet step on the footrest 3 and rotate vertically, the footrest 3 can drive the sliding block 7 to rotate vertically. The sliding block 7 drives the guide rod 6 to rotate vertically. The guide rod 6 drives the support frame 5 to rotate vertically. The support frame 5 causes the linkage block 4 to rotate vertically. The linkage block 4 drives the offset block 2 to rotate vertically. The offset block 2 causes the positioning shaft 11 to rotate vertically. The positioning shaft 11 drives the exercise table 1 to rotate vertically.

[0037] The exercise platform 1 drives the sleeve 20 to rotate vertically. The sleeve 20 rotates vertically while being positioned on the outer wall of the limiting shaft 29, and the handheld frame 30 supports the limiting shaft 29. At the same time, the sleeve 20 drives the arc block 21 to rotate vertically. The arc block 21 rotates vertically along the outer wall of the guide rail 22 and along the inner wall of the outer frame 23. Simultaneously, the arc block 21 pulls the second offset elastic band 25, which pulls between the two limiting bars 26. The second offset elastic band 25 provides elastic force to the arc block 21, thus pulling the positioning sleeve 27. The reinforcing bar 24 supports the support shaft 28, and the support shaft 28 positions the positioning sleeve 27. In this way, the two foot pedals 3 can achieve vertical rotation adjustment exercise. The two foot pedals 3 can also perform lateral rotation exercise adjustment during vertical rotation adjustment exercise, and can also adjust the distance between the two foot pedals 3. This multi-dimensional adjustment exercise results in a more effective lower limb adjustment exercise.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
