The first traction part is wound around a first pulley, and its two ends are connected with the first pedal and the second pedal respectively to drive the first pulley to rotate, and when the first pedal goes up, the second pedal goes down, or when the first pedal goes down, the second pedal goes up. The second traction part is wound around a second pulley, and its two ends are connected with the first pedal and the second pedal respectively to drive the second pulley to rotate, and when the first pedal goes up, the second pedal goes down, or when the first pedal goes down, the second pedal goes up. The two ends of the first traction part and the second traction part cross each other, so that the rotating direction of the second pulley is opposite to that of the first pulley. Under the action of the first one-way bearing and the second one-way bearing, one of the first pulley and the second pulley drives the rotating part to rotate, so that the speed inertia is not lost. The resistance part provides resistance to the rotating part when the rotating part rotates. Since the speed inertia is guaranteed, the stability of the resistance is guaranteed, and the movement is more smooth.

[0020] Option 7, based on Option 1, has grooves on the first pulley and the second pulley, and the first traction member or the second traction member is adapted to be embedded in the grooves.

[0021] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0022] 1. In Scheme 1 and its preferred embodiments, a mountaineering machine includes a main frame, a rotating component, a first wheel assembly, a second wheel assembly, a first pedal, a second pedal, a first traction component, a second traction component, and a resistance component.

[0023] The main frame is used for mounting other parts.

[0024] The rotating component is rotatably connected to the main frame and is adapted to rotate unidirectionally relative to the main frame in the first circumferential direction; it is provided with a shaft.

[0025] The first wheel assembly includes a first one-way bearing and a first pulley sleeved on the first one-way bearing. The first pulley is adapted to rotate relative to the main frame in a first circumferential direction and in opposite directions. The first one-way bearing is sleeved on the shaft and drives the rotating component to rotate in the first circumferential direction when the first pulley rotates in the first circumferential direction, thereby driving the rotating component in one direction.

[0026] The second wheel assembly includes a second one-way bearing and a second pulley sleeved on the second one-way bearing. The second pulley is adapted to rotate relative to the main frame in a first circumferential direction and in opposite directions. The second one-way bearing is sleeved on the shaft and drives the rotating component to rotate in the first circumferential direction when the second pulley rotates in the first circumferential direction, thereby driving the rotating component in one direction.

[0027] Both the first and second pedals are suitable for lifting relative to the main frame and are also suitable for being subjected to force by the user.

[0028] The first traction member is wound around the first pulley, and its two ends are respectively connected to the first pedal and the second pedal to drive the first pulley to rotate, and to lower the second pedal when the first pedal rises, or to raise the second pedal when the first pedal falls.

[0029] The second traction component winds around the second pulley, with its two ends connected to the first and second pedals respectively, to drive the second pulley to rotate. When the first pedal rises, the second pedal falls, or when the first pedal falls, the second pedal rises. Its two ends cross each other so that the rotation direction of the second pulley is opposite to that of the first pulley. Under the action of the first and second one-way bearings, one of the first and second pulleys drives the rotating component to rotate continuously, ensuring that velocity inertia is not lost. The resistance component provides resistance to the rotating component as it rotates. Because velocity inertia is guaranteed, the stability of the resistance is ensured, resulting in smoother movement.

[0030] 2. In Scheme 2 and its preferred embodiment, the reversing wheel is rotatably connected to the main frame. The two ends of the second traction member cross each other and abut against the two opposing surfaces of the reversing wheel. During operation, the second traction member also acts on the reversing wheel, causing the reversing wheel to rotate to reduce friction and to a certain extent restrict the position of the second traction member, making the cross position of the second traction member more stable and ensuring smooth movement.

[0031] 3. In Scheme 3 and its preferred embodiments, the first wheel assembly further includes a first deep groove ball bearing, a first pulley sleeved on the first deep groove ball bearing, and the first deep groove ball bearing sleeved on the shaft; the second wheel assembly further includes a second deep groove ball bearing, a second pulley sleeved on the second deep groove ball bearing, and the second deep groove ball bearing sleeved on the shaft. The first and second deep groove ball bearings can provide smooth rotation and bear the required load, ensuring the stability and performance of the mountaineering machine.

[0032] 4. In Scheme 4 and its preferred embodiments, the retaining ring is engaged with the shaft and is located on both sides of the first pulley and / or the second pulley along the extension direction of the shaft, so as to limit the position of the first pulley and / or the second pulley along the extension direction of the shaft and prevent the first pulley and / or the second pulley from displacing along the extension direction of the shaft during the movement, affecting the force application and causing discomfort during use.

[0033] 5. In Scheme 5 and its preferred embodiments, the resistance component is a magnetically controlled wheel assembly. By controlling the size of the magnetic gap, the required resistance can be freely adjusted to achieve the training effect, which is simple and convenient.

[0034] 6. In Scheme Six and its preferred embodiments, the magnetically controlled wheel assembly includes a rotor, which is connected to the rotating component via a belt drive to achieve transmission. Compared to the rotor being a directly rotating component, this method allows the magnetically controlled wheel assembly to use existing components without requiring separate design. Furthermore, the belt drive provides greater flexibility in the installation location of the magnetically controlled wheel assembly, enabling it to be installed in locations with ample space, thus facilitating installation.

[0035] 7. In Scheme 7 and its preferred embodiments, the first pulley and the second pulley are provided with grooves, and the first traction member or the second traction member is adapted to be embedded in the grooves to limit the position of the first traction member and the second traction member, prevent the first traction member from disengaging from the first pulley, and the second traction member from disengaging from the second pulley, so as to ensure the stability of the use process.

[0051] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0052] A climbing machine includes a main frame 1, a rotating component 2, a first wheel assembly 3, a second wheel assembly 4, a first pedal 51, a second pedal 52, a first traction component 61, a second traction component 62, a resistance component 7, a reversing wheel 8, a retaining ring 9, and a belt 10.

[0053] refer to Figure 1 The main frame 1 is located on the ground and is used for mounting other parts.

[0054] refer to Figure 1 , Figure 2 The rotating part 2 is rotatably connected to the main frame 1 and is adapted to rotate unidirectionally relative to the main frame 1 in the first circumferential direction. The rotating part 2 is provided with a shaft 21 and a wheel 22 fixedly connected to the shaft 21.

[0055] refer to Figure 3 The first wheel assembly 3 includes a first one-way bearing 31, a first deep groove ball bearing 32, and a first pulley 33. The first pulley 33 is sleeved on the first one-way bearing 31 and the first deep groove ball bearing 32. The first pulley 33 is adapted to rotate relative to the main frame 1 in a first circumferential direction and in the opposite direction of the first circumferential direction. The first pulley 33 is provided with a groove. The first one-way bearing 31 is sleeved on the shaft 21 and drives the rotating component 2 to rotate in the first circumferential direction when the first pulley 33 rotates in the first circumferential direction. When the first pulley 33 rotates in the opposite direction of the first circumferential direction, it does not drive the rotating component 2 to rotate. The first deep groove ball bearing 32 is sleeved on the shaft 21.

[0056] refer to Figure 3 The second wheel assembly 4 includes a second one-way bearing 41, a second deep groove ball bearing 42, and a second pulley 43. The second pulley 43 is fitted onto the second one-way bearing 41 and the second deep groove ball bearing 42. The second pulley 43 is adapted to rotate relative to the main frame 1 in a first circumferential direction and in the opposite direction of the first circumferential direction. The second one-way bearing 41 is fitted onto the shaft 21 and drives the rotating component 2 to rotate in the first circumferential direction when the second pulley 43 rotates in the first circumferential direction. When the second pulley 43 rotates in the opposite direction of the first circumferential direction, it does not drive the rotating component 2 to rotate. The second deep groove ball bearing 42 is fitted onto the shaft 21.

[0057] refer to Figure 3 The retaining ring 9 is roughly C-shaped and engages with the shaft 21. It is located on both sides of the first pulley 33 and / or the second pulley 43 along the extension direction of the shaft 21, respectively, to limit the position of the first pulley 33 and / or the second pulley 43 along the extension direction of the shaft 21, so as to prevent the first pulley 33 and the second pulley 43 from displacing and causing instability during use.

[0058] refer to Figure 3 The first pedal 51 and the second pedal 52 correspond to the user's right foot and left foot, respectively. The first pedal 51 and the second pedal 52 are spaced apart in the vertical direction and are both suitable for lifting and lowering relative to the main frame 1.

[0059] refer to Figure 2 , Figure 4 The reversing wheel 8 is rotatably connected to the main frame 1, and the reversing wheel 8 also has a groove.

[0060] refer to Figure 2 , Figure 4 The first traction member 61 is used to drive the first pulley 33 to rotate when the first pedal 51 and the second pedal 52 are actuated, and to make the first pedal 51 and the second pedal 52 move together. The first traction member 61 is wrapped around the first pulley 33 and embedded in the groove of the first pulley 33. The two ends of the first traction member 61 are respectively connected to the first pedal 51 and the second pedal 52. When the first pedal 51 rises, it causes the second pedal 52 to fall, and when the first pedal 51 falls, it causes the second pedal 52 to rise. Since the first traction member 61 is wrapped around the first pulley 33 and embedded in the groove of the first pulley 33, there is friction between the first traction member 61 and the first pulley 33. During the raising and lowering of the first pedal 51, the first pulley 33 is driven to rotate by the friction.

[0061] refer to Figure 2 , Figure 4The second traction member 62 is used to drive the second pulley 43 to rotate when the first pedal 51 and the second pedal 52 are actuated, and to make the first pedal 51 and the second pedal 52 move together. The second traction member 62 is wrapped around the second pulley 43 and embedded in the groove of the second pulley 43. The two ends of the second traction member 62 cross each other. After the two ends of the second traction member 62 cross each other, they respectively abut against the two opposing surfaces of the reversing wheel 8, and then connect to the first pedal 51 and the second pedal 52 respectively. When the first pedal 51 rises, the second pedal 52 falls, and when the first pedal 51 falls, the second pedal 52 rises. Similarly, during the raising and lowering of the first pedal 51, the second traction member 62 drives the second pulley 43 to rotate. And because the two ends of the second traction member 62 cross each other, the rotation direction of the second pulley 43 is opposite to the rotation direction of the first pulley 43.

[0062] To ensure strength, the first traction member 61 and the second traction member 62 can be steel wire ropes.

[0063] refer to Figure 2 , Figure 4 The resistance element 7 is adapted to provide resistance to the rotating element 2 when it rotates. In this embodiment, the resistance element 7 is a magnetically controlled wheel assembly. The magnetically controlled wheel assembly includes a rotor 71, which is connected to the wheel body 22 of the rotating element 2 via a belt 10. In other embodiments, the resistance element 7 can be replaced by other forms of machinery, such as applying a biasing force to the rotating element 2 through an elastic element to increase resistance.

[0064] When using it, take the first circumference as clockwise, with the first pedal 51 corresponding to the right foot and the second pedal 52 corresponding to the left foot as an example.

[0065] refer to Figure 5 , Figure 6 When the first pedal 51 descends and the second pedal 52 ascends, under the action of the reversing wheel 8, the second traction member 62 drives the second pulley 43 to rotate counterclockwise. Due to the action of the second one-way bearing 41, the second one-way bearing 41 does not drive the rotating member 2 to rotate at this time. Meanwhile, the first traction member 61 drives the first pulley 33 to rotate clockwise, at which time the first one-way bearing 31 can drive the rotating member 2 to rotate clockwise.

[0066] refer to Figure 7 , Figure 8 When the first pedal 51 rises and the second pedal 52 falls, the first traction member 61 drives the first pulley 33 to rotate counterclockwise. At this time, the first one-way bearing 31 does not drive the rotating member 2 to rotate. Under the action of the reversing wheel 8, the second traction member 62 drives the second pulley 43 to rotate clockwise. Due to the action of the second one-way bearing 41, the second one-way bearing 41 drives the rotating member 2 to rotate clockwise.

[0067] During the operation, the rotating part 2 always rotates clockwise, and the rotating part 2, through the belt 10, makes the rotor 71 always rotate in the same direction, maintaining speed inertia, thereby ensuring the stability of resistance and making the movement smoother.

[0068] Compared with the prior art, this embodiment has the following beneficial effects:

[0069] In one exemplary embodiment, a mountaineering machine includes a main frame 1, a rotating component 2, a first wheel assembly 3, a second wheel assembly 4, a first pedal 51, a second pedal 52, a first traction component 61, a second traction component 62, and a resistance component 7.

[0070] Main frame 1, used for mounting other parts.

[0071] The rotating component 2 is rotatably connected to the main frame 1 and is adapted to rotate unidirectionally relative to the main frame 1 in the first circumferential direction, and is provided with a shaft 21;

[0072] The first wheel assembly 3 includes a first one-way bearing 31 and a first pulley 33 sleeved on the first one-way bearing 31. The first pulley 33 is adapted to rotate relative to the main frame 1 in a first circumferential direction and in the opposite direction of the first circumferential direction. The first one-way bearing 31 is sleeved on the shaft 21 and drives the rotating component 2 to rotate in the first circumferential direction when the first pulley 33 rotates in the first circumferential direction, so as to drive the rotating component 2 in one direction.

[0073] The second wheel assembly 4 includes a second one-way bearing 41 and a second pulley 43 sleeved on the second one-way bearing 41. The second pulley 43 is adapted to rotate relative to the main frame 1 in a first circumferential direction and in the opposite direction of the first circumferential direction. The second one-way bearing 41 is sleeved on the shaft 21 and drives the rotating member 2 to rotate in the first circumferential direction when the second pulley 43 rotates in the first circumferential direction, so as to drive the rotating member 2 in one direction.

[0074] Both the first pedal 51 and the second pedal 52 are adapted to be raised and lowered relative to the main frame 1, and both are adapted to be subjected to force by the user.

[0075] The first traction member 61 is wound around the first pulley 33, and its two ends are respectively connected to the first pedal 51 and the second pedal 52 to drive the first pulley 33 to rotate, and to lower the second pedal 52 when the first pedal 51 rises, or to raise the second pedal 52 when the first pedal 51 falls.

[0076] The second traction member 62 is wound around the second pulley 43, and its two ends are connected to the first pedal 51 and the second pedal 52 respectively to drive the second pulley 43 to rotate. When the first pedal 51 rises, the second pedal 52 falls, or when the first pedal 51 falls, the second pedal 52 rises. Its two ends cross each other so that the rotation direction of the second pulley 43 is opposite to that of the first pulley 33. Under the action of the first one-way bearing 31 and the second one-way bearing 41, one of the first pulley 33 and the second pulley 43 will drive the rotating member 2 to rotate continuously, so that the speed inertia is not lost. The resistance member 7 provides resistance to the rotating member 2 when the rotating member 2 rotates. Since the speed inertia is guaranteed, the stability of the resistance is guaranteed, and the movement is smoother.

[0077] In one exemplary embodiment, the reversing wheel 8 is rotatably connected to the main frame 1. The two ends of the second traction member 62 cross each other and abut against the two opposing surfaces of the reversing wheel 8. During operation, the second traction member 62 also acts on the reversing wheel 8, causing the reversing wheel 8 to rotate to reduce friction and to a certain extent restrict the position of the second traction member 62, making the cross position of the second traction member 62 more stable and ensuring smooth movement.

[0078] In one exemplary embodiment, the first wheel assembly 3 further includes a first deep groove ball bearing 32, a first pulley 33 sleeved on the first deep groove ball bearing 32, and the first deep groove ball bearing 32 sleeved on the shaft 21; the second wheel assembly 4 further includes a second deep groove ball bearing 42, a second pulley 43 sleeved on the second deep groove ball bearing 42, and the second deep groove ball bearing 42 sleeved on the shaft 21. The first deep groove ball bearing 32 and the second deep groove ball bearing 42 can provide smooth rotation and bear the required load, ensuring the stability and performance of the mountaineering machine.

[0079] In one exemplary embodiment, the retaining ring 9 engages with the shaft 21 and is located on both sides of the first pulley 33 and / or the second pulley 43 along the extension direction of the shaft 21, respectively, to limit the position of the first pulley 33 and / or the second pulley 43 along the extension direction of the shaft 21, and to prevent the first pulley 33 and / or the second pulley 43 from displacing along the extension direction of the shaft 21 during the movement, thus affecting the force application and causing discomfort during use.

[0080] In one exemplary embodiment, the resistance element 7 is a magnetically controlled wheel assembly. By controlling the size of the magnetic gap, the required resistance can be freely adjusted to achieve the training effect, which is simple and convenient.

[0081] In one exemplary embodiment, the magnetically controlled wheel assembly includes a rotor 71, which is connected to the rotating component 2 via a belt 10 for transmission. Compared to the rotor 71 being directly the rotating component 2, this method allows the magnetically controlled wheel assembly to use existing components without requiring separate design. Furthermore, the belt 10 transmission provides greater flexibility in installation location, allowing for installation in larger spaces and facilitating installation. In other embodiments, the rotating component 2 can also be directly the rotor 71.

[0082] In one exemplary embodiment, the first pulley 33 and the second pulley 43 are provided with grooves, and the first traction member 61 or the second traction member 62 is adapted to be embedded in the grooves to limit the position of the first traction member 61 and the second traction member 62, prevent the first traction member 61 from disengaging from the first pulley 33 and the second traction member 62 from disengaging from the second pulley 43, and ensure the stability of the use process.

[0083] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
