Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically a splits training machine. Background Technology

[0002] The split machine is a common fitness equipment used in the fitness field to exercise the stretching or contraction of the muscles and tendons on the inner and outer sides of the legs. Existing split machines all achieve simultaneous opening and closing of both legs. For example, patent CN202237021U discloses a split machine including a frame, handrails, pedal assembly, and damping device. The frame consists of left and right slide rails, a rear support, and a middle support connecting the left and right slide rails and the rear support. The left and right slide rails extend outward from the connecting end of the frame, forming an arc-shaped rail with a certain curvature. The handrails are located at the front end of the frame, and the upper end of the handrails is equipped with a handrail. The pedal assembly consists of left and right pedal supports and left and right pedals, which are correspondingly installed on the left and right pedal supports. The front ends of the left and right pedal supports slide on the left and right slide rails, and the rear ends form a rotatable pivot connection with the rear support. The damping device is located on the frame and consists of two sets of elastic pull ropes and several guide wheels. The two ends of the elastic pull ropes are stretchably connected to the inner and outer ends of the left and right slide rails and form a detachable connection with the inner or outer side of the pedal assembly. While existing split machines can exercise both legs, they require both legs to be used simultaneously. This is not suitable for individuals with single-leg injuries who need rehabilitation exercises. Utility Model Content

[0034] Reference Figures 1 to 3 , Figures 5 to 7 The shaft 53 has a front threaded hole 531 at its front end and an external thread 532 and a rear threaded hole 533 at its rear end. The front end of the front connecting pipe 12 has a front screw 121 that is threadedly connected to the front threaded hole 531. The clamping device 55 includes a front clamping tooth 551, a rear clamping tooth 552, and a knob 553. The front clamping tooth 551 is welded to the rear end of the rear connecting pipe 22.

[0035] Reference Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 The bottom of the front fixing tube 13 is provided with a first hinge member 14. Below the front fixing tube 13 is a rotating member 15 that is hinged to the first hinge member 14. The first hinge member 14 is provided with a torsion spring 16 that abuts against the rotating member 15. The front end of the rotating member 15 is provided with a pressing part 151, and the rear end of the rotating member 15 is provided with a plug rod 152. The track connecting tube 51 arranged in front is provided with a socket 511 for the plug rod 152 to be inserted. When the arc-shaped track 4 is unfolded, the plug rod 152 is misaligned with the socket 511. When the arc-shaped track 4 is folded, the track connecting tube 51 rotates with it. When the arc-shaped track 4 is folded into place, the plug rod 152 is inserted into the socket 511.

[0036] Reference Figures 2 to 10 The arc-shaped track 4 and pedal 6 can be folded. Rotate the arc-shaped track 4 to the left to a vertical position. At this time, insert rod 152 into insertion hole 511. Then rotate pedal 6 and left support 3 to the right to a vertical position. Then rotate knob 553 clockwise. When knob 553 is rotated clockwise, it will move forward and push rear locking tooth 552 forward. As knob 553 rotates clockwise, rear locking tooth 552 engages with front locking tooth 551. After the rear locking tooth 552 and front locking tooth 551 are engaged, continue to rotate knob 553 clockwise. At this time, knob 553 can no longer move forward. As knob 553 continues to rotate clockwise, shaft 53 will be pulled backward, so that front fixing tube 13, two track connecting tubes 51, pedal connecting tube 52 and rear fixing tube 23 are pressed together. In this way, the folded arc-shaped track 4 and pedal 6 can be fixed. When the curved track 4 and pedal 6 are to be unfolded for use, rotate the knob 553 counterclockwise. The shaft 53 moves forward to reset, loosening the front fixing tube 13, the two track connecting tubes 51, the pedal connecting tube 52, and the rear fixing tube 23. Continue rotating the knob 553 counterclockwise to move it backward. Under the action of the spring 554, the rear locking tooth 552 automatically resets backward. Finally, press the pressing part 151 upward, causing the rear end of the rotating part 15 to move downward. The insert rod 152 disengages from the insertion hole 511, at which point the curved track 4 and pedal 6 can be unfolded for use. The locking device 55 and the cooperation between the insert rod 152 and the insertion hole 511 provide a double fixing effect, ensuring that the curved track 4 and pedal 6 will not fall apart after folding.

[0037] Reference Figure 1 and Figure 10The bottom of the end tube 42 is provided with a second hinge member 43. The bottom and left end of the second hinge member 43 are both open structures. The top of the support rod 9 is hinged to the second hinge member 43. The top of the support rod 9 is provided with a first pin hole (not shown in the figure due to view limitations). The second hinge member 43 is provided with a second pin hole 431 and a third pin hole 432 arranged vertically. An elastic pin 44 passes through the second hinge member 43. The elastic pin 44 passes through the first pin hole (not shown in the figure due to view limitations) and the second pin hole 431 / third pin hole 432. When the arc-shaped track 4 is unfolded, the support rod 9 also unfolds to support the arc-shaped track 4. At this time, the elastic pin 44 passes through the first pin hole (not shown in the figure due to view limitations) and the third pin hole 432. When the arc-shaped track 4 needs to be folded, the support rod 9 is folded first, that is, the elastic pin 44 is pulled out, and then the support rod 9 is folded. After the support rod 9 is folded, the elastic pin 44 is inserted through the first pin hole (not shown in the figure due to view limitations) and the second pin hole 431, thereby fixing the folded support rod 9.

[0038] Reference Figure 1 and Figure 4 The bottom of the pedal connecting tube 52 is provided with a first connector 50, which has multiple first latches 501 arranged front to back. The bottom of the slide support tube 71 is provided with a second connector 75, which has multiple second latches 751 arranged front to back. A third connector 45 is provided between the right ends of the two arc-shaped tubes 41, which has multiple third latches 451 arranged front to back. The damping structure 8 is a latex tube, one end of which is locked in the second latch 751, and the other end of which can be locked in the first latch 501 / third latch 451. The latex tube is provided with at least one. When it is necessary to increase / decrease the resistance, the number of latex tubes can be increased / decreased. The number of latex tubes can be selected as needed, such as one, two, three, etc. The other end of the latex tube can be selected to be locked in the first locking slot 501 or the third locking slot 451. Both methods can provide resistance to the slide plate 7 when it slides on the arc track 4.

[0039] Reference Figure 1 This invention allows users with a single leg injury requiring rehabilitation to perform stretching or contraction of the inner and outer muscles and tendons. When the user needs to exercise, they should maintain a sideways position, hold onto the handrail 10, place the foot that does not need rehabilitation on the pedal 6, and place the foot that needs rehabilitation on the skateboard 7, pushing the skateboard 7 back and forth along the curved track 4. The leg requiring rehabilitation can then undergo rehabilitation exercises. Of course, if the user happens to need to exercise their right leg, they can also exercise upright.
