Description

Technical Field

[0001] This utility model relates to the field of sports exercise equipment technology, specifically to a ski machine with adjustable and resettable pull rope. Background Technology

[0002] A ski machine is a new type of home fitness equipment that primarily activates the adductor muscles of the thighs and strengthens deep leg muscles through a lateral sliding mechanism. A spring is needed between the two pedals to provide resistance. Traditionally, a spring is directly connected between the two pedals. Since the spring itself has a certain length when contracted, it contacts the ground when the pedals come together. The reciprocating motion of the pedals causes the spring to rub and slap against the ground, shortening its lifespan, scratching the surface, and producing unpleasant noise. Furthermore, traditional ski machine pedals are open-topped, and although they have friction particles, beginners or those with insufficient leg strength often slip off the pedals.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes a ski machine with adjustable and resetting pull rope, which can overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] A ski machine with adjustable and resettable pull rope includes a frame, a crossbar, and a column. The middle part of the frame is fixedly connected to the crossbar. The front end of the crossbar is provided with the column, which is perpendicularly connected to it. The frame has pedals on both sides of the crossbar that are slidably connected to the frame. Both the crossbar and the column have cavities inside. An adjusting rod is sleeved on the upper part of the column. The bottom of the adjusting rod is provided with a connecting rod that is fixedly connected to it. The connecting rod is movably connected to the column via bolts and knobs. The bottom end of the connecting rod is connected to the top end of a tension spring. The bottom end of the tension spring is provided with a pulley. The column cavity has an L-shaped double pulley at the connection point with the crossbar. The crossbar cavity has a horizontal double pulley in the middle. Pull ropes are provided on the pulleys. The two ends of the pull ropes pass through the L-shaped double pulleys and the horizontal double pulleys, respectively, and are connected to the corresponding pedals.

[0007] Furthermore, the crossbar is provided with rope passage holes on both sides of the double pulley, and both ends of the pull rope pass through the corresponding rope passage holes and are connected to the corresponding pedal.

[0008] Furthermore, the horizontal double pulleys are fixedly connected to the inner wall of the crossbar via a semi-circular pad.

[0009] Furthermore, the L-shaped double pulley is fixedly connected to the inner wall of the column via a semi-circular pad.

[0010] Furthermore, the connecting rod is connected to the top of the tension spring via a pull ring.

[0011] Furthermore, the upper part of the pedal is provided with straps.

[0012] Furthermore, the bottom of the rear end of the crossbar is provided with a vertical support, and the bottom of the column is provided with a horizontal support.

[0013] The beneficial effects of this utility model are as follows: By setting the tension spring inside the column cavity, the tension of the tension spring is transmitted through the pulley system and the rope. This not only meets the tension required for exercise, but also enables automatic retraction. It solves the problem of poor experience caused by the tension spring contacting the ground in the prior art. In addition, the straps on the pedal also solve the problem of unstable footing for beginners. It has great practical value. Attached Figure Description

The frame body 1 is provided with pedals 5 on both sides of the crossbar 2, which are slidably connected to the frame body 1. Both the crossbar 2 and the column 3 have cavities inside. An adjusting rod 4 is sleeved on the upper part of the column 3. The bottom of the adjusting rod 4 is provided with a... The connecting rod 13 is fixedly connected to the column 3 via bolts and knobs 12. The bottom end of the connecting rod 13 is connected to the top end of the tension spring 10. The bottom end of the tension spring 10 is provided with a pulley 9. The cavity of the column 3 is provided with an L-shaped double pulley 8 at the connection with the crossbar 2. The cavity of the crossbar 2 is provided with a horizontal double pulley 7 in the middle. The pulley 9 is provided with a pull rope 6. The two ends of the pull rope 6 pass through the L-shaped double pulley 8 and the horizontal double pulley 7 respectively and are connected to the corresponding pedal 5.

[0021] In this embodiment, the crossbar 2 is provided with rope holes 11 on both sides of the double pulley 7, and both ends of the pull rope 6 pass through the corresponding rope holes 11 and are connected to the corresponding pedal 5.

[0022] In this embodiment, the horizontal double pulley 7 is fixedly connected to the inner wall of the crossbar 2 via a semi-circular pad 14.

[0023] In this embodiment, the L-shaped double pulley 8 is fixedly connected to the inner wall of the column 3 via a semi-circular pad 15.

[0024] In this embodiment, the connecting rod 13 is connected to the top end of the tension spring 10 via a pull ring.

[0025] In this embodiment, the upper part of the pedal 5 is provided with a strap 16.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0028] In practical use, the ski machine with adjustable and resetting pull rope according to this utility model includes a frame body 1, a crossbar 2, a column 3, an adjusting rod 4, a pedal 5, and a pull rope 6.

[0029] The inner cavity of the crossbar 2 is provided with a rope passage hole 11, and a horizontal double pulley 7 is provided near the rope passage hole 11. The horizontal double pulley 7 is provided with a semi-circular pad 14 and is fixed to the inner wall of the crossbar 2 by conventional bolts.

[0030] The bottom of the column 3 is provided with an L-shaped double pulley 8, and the L-shaped double pulley 8 is provided with a semi-circular washer 15 and is fixed to the inner wall of the column 3 by conventional bolts.

[0031] The adjusting rod 4 has a connecting rod 13 at its bottom. A tension spring 10 is connected to the circular hole on the connecting rod 13. A pulley 9 is connected to the bottom of the tension spring 10.

[0032] The connecting rod 13 is fixed to the column 3 by conventional bolts and knobs 12.

[0033] The pedal 5 is equipped with a strap 16.

[0034] The pull rope 6 passes through the pulley 9, and then through the L-shaped double pulley 8 at both ends, followed by the horizontal double pulley 7, and finally out through the rope hole 11. The two ends of the pull rope 6 are fixed to the pedals 5 on both sides.

[0035] Furthermore, the adjusting rod 4 can adjust the height and tension of the pull rope 6 on the column 3, and then tighten it with the bolt knob 12.

When the pedals 5 are retracted inwards, the tension spring 10 pulls upwards, causing the pull rope 6 to retract towards the rope hole.

[0037] Because the tension of the pull rope is adjustable, and through the action of the pulley system and tension spring, it not only meets the pulling force required for exercise but also allows for easy retraction. The straps on the pedals also solve the problem of instability for beginners.

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, by setting the tension spring inside the column cavity, the tension of the tension spring is transmitted through the pulley system and the pull rope, which not only meets the tension required for exercise, but also enables automatic retraction. This solves the problem of poor experience caused by the tension spring contacting the ground in the prior art. Furthermore, the straps on the pedal also solve the problem of instability for beginners. It has great practical value.
