[0027] Embodiment 1

[0028] As Figures 1-4As shown, the present invention provides a tension fitness device, including a fixed component, a winding component 2 and four sliding wheel groups 6. The fixed component includes a frame and a track, and the frame includes two parallel longitudinal beams 12 and an upper crossbeam 11 and a lower crossbeam (not shown in the figure) fixedly connected between the two longitudinal beams 12. The track includes two parallel first tracks 41 and two parallel second tracks 42, the first track 41 is fixedly connected to the bottom of the frame, the lower end of the second track 42 is fixedly connected to the first track 41, and the upper end of the second track 42 is fixedly connected to the frame. The second track 42 is set at an angle with the longitudinal beam 12, so as to optimize the force distribution during use. The four sliding wheel groups 6 are divided into two groups, one group of sliding wheel groups 6 can slide with the two first tracks 41, and the other group of sliding wheel groups 6 can slide with the two second tracks 42. A positioning member 62 is provided on the sliding wheel group 6, and the positioning member 62 is used to fix the sliding wheel group 6 on the first track 41 or the second track 42. The wire winding assembly 2 is installed on the fixed assembly, specifically, the wire winding assembly 2 is installed at the lower end of the frame and is located between the second track 42 and the frame to reduce space occupation. One end of the tension line 3 is wound on the wire winding assembly 2, and the wire winding assembly 2 is used to wind up the tension line 3 and apply tension to the tension line 3. The sliding wheel group 6 is provided with a fixed pulley 64, and the other end of the tension line 3 is wound on the fixed pulley 64 and connected to a handle 651. A reversing pulley 51 is also provided at the corner of the first track 41 and the second track 42 to achieve reversal of the tension line 3. The wire winding assembly 2 includes a wire winding motor and a drum, and the wire winding motor drives the drum to rotate to achieve winding up the tension line 3, and as the tension line 3 is stretched, the tension applied by the wire winding motor to the tension line 3 gradually increases. Correspondingly, in this embodiment, two winding assemblies 2 are provided, and the two winding assemblies 2 are respectively installed on the two longitudinal beams 12, that is, located on both sides of the tension fitness machine, and the two tension lines 3 are respectively connected to the sliding wheel groups 6 on the two first rails 41 or respectively connected to the sliding wheel groups 6 on the two second rails 42. In other embodiments, a winding motor with a dual output shaft can also synchronously drive the two reels to reel in the tension lines 3, and the tension lines 3 on both sides of the tension fitness machine can also be reeled in. By providing the first rail 41 and the second rail 42, and providing the sliding wheel groups 6 that can slide with them on the first rail 41 and the second rail 42, and fixing the sliding wheel groups 6 by the positioning members 62, the position of the sliding wheel groups 6 can be adjusted by sliding, and then the position of the ends of the tension lines 3 can be changed, and the process of switching positions is faster and more convenient, and the whole process does not involve disassembly and reinstallation, which greatly improves the user experience.

[0029] Further, to enable the tensile fitness device to meet the diverse training needs of users, in this embodiment, two winding components 2 are provided on each side of the tensile fitness device. The tensile wire 3 wound on one of the winding components 2 is wound around the sliding wheel set 6 that is slidably engaged with the first track 41, and the tensile wire 3 wound on the other winding component 2 is wound around the sliding wheel set 6 that is slidably engaged with the second track 42. That is, four winding components 2 respectively wind four strands of tensile wires 3, and the four strands of tensile wires 3 are respectively connected to four sliding wheel sets 6. Thus, the user can choose to use the tensile wire 3 connected to the two sliding wheel sets 6 on the first track 41 for training, or can also choose to use the tensile wire 3 connected to the two sliding wheel sets 6 on the second track 42 for training. In other embodiments, two winding drums can also be provided. The tensile wires 3 wound on the two winding drums are respectively connected to the sliding wheel sets 6 on the first track 41 and the second track 42. A sliding sleeve is provided between the two winding drums. By switching the position of the sliding sleeve, one of the two winding drums is engaged with the output shaft of the winding motor, which reduces the number of components and the occupied volume while meeting the diverse training needs of users.

[0030] Specifically, please refer to Figures 3-4 As shown, the sliding wheel set 6 further includes a housing 61, and the housing 61 is used for slidably engaging with the first track 41 or the second track 42. Two fixed pulleys 64 are provided, and the two fixed pulleys 64 are rotatably provided on the housing 61 and are spaced along the length direction of the first track 41 or the second track 42. The positioning member 62 passes through the housing 61 and restricts the housing 61 from sliding along the first track 41 or the second track 42. By providing two fixed pulleys 64, no matter from which direction the tensile wire 3 is led out, it can be wound around one of the fixed pulleys 64, improving the convenience of use. Accommodating grooves 43 are provided on the outer sides of both the first track 41 and the second track 42, and the accommodating grooves 43 extend along the length direction of the first track 41 or the second track 42. The housing 61 is slidably engaged with the inner wall of the accommodating groove 43, and the side wall of the accommodating groove 43 can restrict the housing 61 from disengaging from the accommodating groove 43. By constraining the housing 61 through the groove wall of the accommodating groove 43, the structure is simple and the reliability is high. In other embodiments, the structure of a dovetail groove and a dovetail slider can also be adopted, which can also realize reliable constraint on the housing 61.

[0031] Furthermore, please refer to Figure 4 As shown, a plurality of adjusting holes 44 are provided on the bottom wall of the accommodating groove 43, and the plurality of adjusting holes 44 are spaced along the length direction of the accommodating groove 43. The positioning member 62 passes through the housing 61 and is inserted into the adjusting holes 44, so as to restrict the sliding of the housing 61 in the accommodating groove 43 through the positioning member 62. The positioning member 62 can be a pin-like component such as a positioning pin or a positioning bolt, or can also be a fastening component such as a bolt. When the positioning member 62 is selected as a bolt, the corresponding adjusting hole 44 is provided as a threaded hole, and the bolt passes through the housing 61 and is threadedly connected to the threaded hole.

[0032] Optionally, to prevent the housing 61 from wearing due to long-term friction in the receiving groove 43, a roller (not shown in the figure) is rotatably connected to the housing 61. The roller is located in the receiving groove 43 and rolls along the side wall of the receiving groove 43. A recess matching the outer edge of the roller is provided on the side wall of the receiving groove 43. The roller rolls in the recess. On the one hand, it ensures that the housing 61 will not swing left and right during movement. On the other hand, it also prevents the roller from slipping out of the receiving groove 43.

[0033] Optionally, the sliding wheel set 6 further includes four wire pressing wheels 63. The four wire pressing wheels 63 are divided into two groups in pairs. The two groups of wire pressing wheels 63 are respectively rotatably connected to both ends of the housing 61. The two wire pressing wheels 63 in each group are spaced apart, and their axes are parallel to the axis of the fixed pulley 64. The distance between the outer edges of the two wire pressing wheels 63 is greater than or equal to the diameter of the tension wire 3. The tension wire 3 passes between the two wire pressing wheels 63 in one group and contacts the outer edge of the wire pressing wheel 63. By providing the wire pressing wheels 63, it is avoided that the tension wire 3 is damaged due to long-term friction with the housing 61.

[0034] When using the tension fitness device in this embodiment for training, the user can select the corresponding tension wire 3 connected to the sliding wheel set 6 according to their own needs for training, and adjust the sliding wheel set 6 to a preset position and then fix it through the positioning member 62 to prevent sliding during use. Since the tension of the tension wire 3 increases as the length of the tension wire 3 increases, different intensity training requirements can be achieved by moving the sliding wheel set 6 closer to or farther from the wire winding assembly 2. However, for some users with higher requirements for training intensity, even if the sliding wheel set 6 is slid to one end of the first track 41 or the second track 42 far from the wire winding assembly 2, their needs cannot be met. Therefore, in this embodiment, another wire winding method is also provided. An end pulley 52 is rotatably connected to the end of the first track 41 far from the wire winding assembly 2. The other end of the tension wire 3 bypasses the end pulley 52 and then winds around the sliding wheel set 6 on the first track 41. With this setting, the total length of the tension wire 3 connected to the sliding wheel set 6 on the first track 41 is equal to the sum of the length of the first track 41 and the length from the sliding wheel set 6 to the end pulley 52. In comparison, the length of the tension wire 3 increases, thus meeting the training needs of users with higher requirements for training intensity. Similarly, an end pulley 52 is rotatably connected to the end of the second track 42 far from the wire winding assembly 2. The other end of the tension wire 3 bypasses the end pulley 52 and then winds around the sliding wheel set 6 on the second track 42. With this setting, the total length of the tension wire 3 connected to the sliding wheel set 6 on the second track 42 is equal to the sum of the length of the second track 42 and the length from the sliding wheel set 6 to the end pulley 52, and the length of the tension wire 3 increases, also meeting the high-intensity training requirements.

[0035] Embodiment 2

[0036] To avoid redundancy, only the differences from the first embodiment will be described in this embodiment. The difference between this embodiment and the first embodiment is that the sliding pulley group 6 in this embodiment further includes a movable pulley 65.

[0037] Please refer to Figure 5 As shown, the sliding pulley group 6 further includes a movable pulley 65. The movable pulley 65 is located between two fixed pulleys 64. The tension line 3 is sequentially wound around one of the fixed pulleys 64 and the movable pulley 65 and then fixed to the other fixed pulley 64. The handle 651 is connected to the axle of the movable pulley 65. After the movable pulley 65 is provided, the training intensity of the user remains unchanged, but the tension received by the tension line 3 is reduced by half, thereby reducing the load on the tension line 3 and extending the service life of the tension line 3.
