TECHNICAL FIELD

[0001] The utility model belongs to the technical field of skiing machine, concretely relates to a skiing machine of single elastic rope. BACKGROUND

[0002] In the prior art skiing machine, elastic ropes are arranged between the pedals and the center seat, which aims to provide elastic resistance to simulate the leg strength resistance during skiing and help the pedals return after sliding. Since the skiing machine has two pedals, an elastic rope is arranged between each pedal and the center seat. The two elastic ropes not only have high installation requirements, but also need to ensure the same length and stress of the two elastic ropes. In addition, the two elastic ropes will make the structure of the skiing machine more complex, and more fixing points and guiding devices are needed to ensure the smooth operation of the elastic ropes. Furthermore, the two elastic ropes will increase the cost of the skiing machine. SUMMARY

It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0036] As shown in Figure 1 and Figure 2 The embodiment provides a single elastic rope skiing machine, which comprises:

[0037] A main seat 1 is provided with two output wheels 3, and the main seat 1 is internally provided with a wheel set;

[0038] An elastic rope 2 is wound around one of the output wheels 3 at one end and is drawn out of the main seat 1, and is wound around the wheel set and then around the other output wheel 3 at the other end and is drawn out of the main seat 1; the two ends of the elastic rope 2 are symmetrically arranged on the two sides of the main seat 1;

[0039] Two pedals are respectively connected with the two ends of the elastic rope 2. Wherein, the connection structure of each pedal with the end of the elastic rope 2 can adopt a clamping structure, a hook structure or a knot fixing structure and the like.

[0040] For the more specific case of the above scheme, the output wheel 3 and the wheel set edge are both annularly provided with a winding groove, and when the elastic rope 2 is wound around the output wheel 3 or the wheel set, the elastic rope 2 is arranged in the winding groove.

[0041] For the more specific case of the main seat 1 and the two output wheels 3 and the wheel set arranged in the main seat 1,

[0042] As shown in Figure 3 and Figure 4 The main seat 1 is quadrangular, and in the embodiment, the main seat 1 is preferably square. The upper portion of the main seat 1 is provided with a main seat cover 14. The bottom portion of the main seat 1 is provided with an output hole 11 for mounting the output wheel 3, and two output wheels 3 are respectively and symmetrically arranged in the output hole 11, and the two ends of the elastic rope 2 are respectively wound around the corresponding output wheels 3 and drawn out of the main seat 1 from the output hole 11.

[0043] As shown in Figure 1 and Figure 4 Each output wheel 3 is provided with an axle 31; and the two output wheels 3 are both vertically arranged in the output hole 11 through the corresponding axles 31.

[0044] Specifically, the two side walls of the output hole 11 are provided with clamping grooves 13, the output wheels 3 are vertically arranged in the output hole 11, and the two ends of the wheel shaft 31 are clamped in the corresponding clamping grooves 13. The structures of the two output wheels 3 arranged in the output hole 11 are the same.

[0045] The output wheel 3 is vertically arranged in the output hole 11, which means that the winding groove of the output wheel 3 is perpendicular to the bottom surface of the main seat 1, so that the elastic rope 2 located inside the main seat 1 can pass through the output wheel 3 and out of the main seat 1.

[0046] As shown in Figure 1 and Figure 4 The wheel set includes two small wheels 4 and several large wheels 5. The two small wheels 4 are arranged close to the two output wheels 3 one by one; the two ends of the elastic rope 2 pass through the corresponding small wheels 4 and then pass through the corresponding output wheels 3 to out of the main seat 1. Since the main seat 1 is square, the large wheels 5 are provided with four, and the four large wheels 5 are arranged at the four corners of the main seat 1 respectively. The winding track of the elastic rope 2 on the two small wheels 4 and the four large wheels 5 is: first passing through one small wheel 4, then passing through the four large wheels 5 at the four corners of the main seat 1 in turn, and finally passing through the other small wheel 4.

[0047] The inside of the main seat 1 is provided with a rotating shaft 12; the middle part of each small wheel 4 and each large wheel 5 is provided with a insertion hole; each small wheel 4 and each large wheel 5 are placed horizontally in the main seat 1 by the rotating shaft 12.

[0048] The rotating shaft 12 is vertically arranged in the main seat 1, and the rotating shaft 12 corresponds to the small wheel 4 and the large wheel 5 one by one, that is, there are six rotating shafts 12 in the main seat 1. In addition, since the diameter of the large wheel 5 when placed horizontally is larger than the diameter of the small wheel 4 when placed horizontally, the diameter of the rotating shaft 12 for installing the large wheel 5 is larger than the diameter of the rotating shaft 12 for installing the small wheel 4.

[0049] The small wheel 4 and the large wheel 5 are placed horizontally in the main seat 1, which means that the winding groove of the small wheel 4 and the large wheel 5 is parallel to the bottom surface of the main seat 1, so that the elastic rope 2 located inside the main seat 1 can pass through the small wheel 4 and the large wheel 5.

[0050] On the basis of the above scheme, a single elastic rope 2 ski machine further includes a rectangular bottom plate and a slide rail located on the rectangular bottom plate, and the slide rail is arranged along the length direction of the rectangular bottom plate. The main seat 1 is arranged in the middle of the slide rail, and the two footboards are respectively arranged on the two sides of the main seat 1 and are slidably arranged on the slide rail.

[0051] The utility model makes further description in combination with working principle:

[0052] The main seat 1 is arranged in the middle of the rectangular bottom plate, one end of the elastic rope 2 passes around one of the output wheels 3 and goes out of the main seat 1, the other end passes around one of the small wheels 4, four large wheels 5, another small wheel 4 in turn, and finally passes around another output wheel 3 and goes out of the main seat 1. Two are respectively arranged on the slide rail of the rectangular bottom plate and are respectively connected with the two ends of the corresponding elastic rope 2.
