[0032] The second crawler mechanism comprises a second bearing roller 3, a fourth bearing roller 5 and a second crawler 7. The second bearing roller 3 and the fourth bearing roller 5 are arranged parallel to each other. Both ends of the second crawler 7 are respectively sleeved on the second bearing roller 3 and the fourth bearing roller 5. That is, the second bearing roller 3 and the fourth bearing roller 5 are connected by transmission through the second crawler 7.
[0033] The tops of the first crawler belt 6 and the second crawler belt 7 are exposed outside the housing 1. One end of the first bearing roller 2 is provided with a first gear 15, and one end of the second bearing roller 3 is provided with a second gear 16. The first gear 15 meshes with the second gear 16, so as to ensure that the first bearing roller 2 and the second bearing roller 3 rotate synchronously during use.
[0034] In this embodiment, it should be noted that, as Figure 1 and Figure 3 shown, the third bearing roller 4, the first bearing roller 2, the second bearing roller 3 and the fourth bearing roller 5 are arranged parallel to each other in sequence along the length direction of the housing 1.
[0035] The technical effects achieved by this embodiment are as follows: During use, place both hands on the first crawler belt 6 and the second crawler belt 7 respectively, and then make reciprocating motions of approaching and moving away with both hands to apply frictional force to the first crawler belt 6 and the second crawler belt 7 to drive their movement, then the muscles of the arms, shoulders, back and chest can be exercised; alternatively, stand on the first crawler belt 6 and the second crawler belt 7 with both feet respectively, and then make reciprocating motions of approaching and moving away with both legs to apply frictional force to the first crawler belt 6 and the second crawler belt 7 to drive their movement, then the muscles of the legs and buttocks can be exercised; the whole fitness device can realize the exercise of multiple muscles in the whole body, and has a compact structure, small occupied space, is convenient to place, and at the same time has a low production and manufacturing cost and is convenient to popularize and apply.
[0036] Embodiment 2
[0037] As Figures 1 to 3 shown, another crawler fitness device provided in this embodiment has a structure including all the contents of Embodiment 1, and only the different parts will be described below.
[0038] In this embodiment, a damping mechanism is further included. The damping mechanism includes a flywheel 13, a flywheel gear 14, a bevel gear 9, a first pulley 26, a fourth pulley 29, a fourth rotating shaft 30 and a first belt 10;
[0039] The flywheel 13 adopts a disc-shaped structure with a large diameter and large weight. The flywheel 13 is rotatably arranged in the housing 1. The rotating shaft of the flywheel 13 is perpendicular to the rotating shaft of the first bearing roller 2. A flywheel gear 14 is provided at the center of the flywheel 13. The bevel gear 9 and the fourth pulley 29 are respectively arranged at both ends of the fourth rotating shaft 30. The bevel gear 9 meshes with the flywheel gear 14;
[0040] Both the first bearing roller 2 and the first gear 15 are arranged on the first rotating shaft 11. The first pulley 26 is arranged at one end of the first rotating shaft 11. Both ends of the first belt 10 are respectively sleeved on the first pulley 26 and the fourth pulley 29.
[0041] In this embodiment, it should be noted that it further includes a first ratchet mechanism 8. The first pulley 26 and the first gear 15 are connected through the first ratchet mechanism 8. When the limbs move closer and apply force to the track surface, driving the first bearing roller 2 to rotate clockwise and engaging the first ratchet mechanism 8 to generate a clockwise rotation, the first pulley 26 is in transmission connection with the first gear 15; when the first ratchet mechanism 8 rotates counterclockwise, the first pulley 26 is not in transmission connection with the first gear 15.
[0042] Furthermore, the operating principle of the damping mechanism is as follows. Taking the example of exercising with both hands propped on the first track 6 and the second track 7 respectively, when both hands move closer, the first track 6 drives the first bearing roller 2 to rotate clockwise, thereby driving the first gear 15 to rotate clockwise. The first gear 15 drives the first pulley 26 to rotate clockwise through the first ratchet mechanism 8. The first pulley 26 drives the fourth pulley 29 to rotate clockwise through the first belt 10. The fourth pulley 29 drives the bevel gear 9 to rotate through the fourth rotating shaft 30. The bevel gear 9 drives the flywheel 13 to rotate through the flywheel gear 14. The flywheel 13 acts as a damping effect using its own weight to prevent the first bearing roller 2 from rotating too fast; when both hands move away, the damping mechanism does not work, and the flywheel 13 decelerates by itself. When both hands move closer next time, it continues to exert a damping effect.
[0043] The technical effect achieved by this embodiment is that by setting the damping mechanism, the movement can be made smoother, safer and more reliable during use. At the same time, a certain amount of resistance can be increased to ensure the exercise effect.
[0044] Embodiment 3
[0045] As Figures 1 to 3 shown, another track fitness device provided in this embodiment has a structure including all the contents of Embodiment 1. Only the different parts will be described below.
[0046] In this embodiment, it further includes a generator 17, and the generator 17 is arranged in the housing 1;
[0047] Both the second bearing roller 3 and the second gear 16 are arranged on the second rotating shaft 12. The second pulley 27 is arranged at one end of the second rotating shaft 12. The third pulley 28 is arranged on the third rotating shaft 25. Both ends of the second belt 19 are respectively sleeved on the second pulley 27 and the third pulley 28, that is, the second pulley 27 and the third pulley 28 are in transmission connection through the second belt 19;
[0048] The third rotating shaft 25 and the generator 17 rotating shaft are connected through a second ratchet mechanism 18. When the third rotating shaft 25 rotates counterclockwise, the second ratchet mechanism 18 is in transmission connection with the generator 17 rotating shaft; when the third rotating shaft 25 rotates clockwise, the second ratchet mechanism 18 is not in transmission connection with the generator 17 rotating shaft.
[0049] The principle of generating electricity using the generator 17 is as follows. Taking the example of exercising with both hands on the first crawler 6 and the second crawler 7 respectively, when the two hands make a closing movement, the second crawler 7 drives the second bearing roller 3 to rotate counterclockwise, thereby driving the second pulley 27 to rotate counterclockwise. The second pulley 27 drives the third pulley 28 to rotate counterclockwise through the second belt 19. The third pulley 28 drives the third rotating shaft 25 to rotate counterclockwise. The third rotating shaft drives the rotating shaft of the generator 17 to rotate counterclockwise through the second ratchet mechanism 18 to generate electricity. When the two hands make a separating movement, under the action of the second ratchet mechanism 18, the rotating shaft of the generator 17 is not affected by force and moves by its own inertia until the two hands make a closing movement again, and then drives the rotating shaft of the generator 17 to rotate again to generate electricity.
[0050] In this embodiment, it should be noted that it further includes a rechargeable battery 32. The rechargeable battery 32 is arranged in the housing 1. The rechargeable battery 32 is electrically connected to the generator 17, and the generator 17 is used to charge the rechargeable battery 32.
[0051] Furthermore, it further includes a mounting seat 20. The mounting seat 20 is arranged in the housing 1, and the generator 17 is fixed on the mounting seat 20.
[0052] The technical effects achieved by this embodiment are: by setting the generator 17, electricity can be generated during the exercise process, thus making full use of energy; by setting the rechargeable battery 32, the electric energy generated by the generator 17 can be stored and used.
[0053] Embodiment 4
[0054] As Figures 1 to 3 shown, another crawler fitness device provided in this embodiment has a structure including all the contents of Embodiment 1. Only the different parts will be described below.
[0055] In this embodiment, it further includes a waist exercise mechanism. The waist exercise mechanism includes an automatic rope winding disc 21, a traction rope 22 and a hand-held pull ring 23. The automatic rope winding disc 21 is arranged in the housing 1. The traction rope 22 is wound on the automatic rope winding disc 21, and one end of the traction rope 22 extends outside the housing 1 and is provided with a hand-held pull ring 23.
[0056] In this embodiment, it should be noted that the waist exercise mechanism further includes a guide wheel 31. The guide wheel 31 is arranged inside the housing 1. One end of the traction rope 22 extends vertically upward out of the housing 1 after being redirected by the guide wheel 31. During use, bend down and use the hand-held pull ring 23 to vertically upwardly pull the traction rope 22 and then stand up. Then bend down again and gradually release the traction rope 22. Under the action of the automatic rope winding disc 21, the traction rope 22 is automatically wound up. Then stand up and vertically upwardly pull the traction rope 22. Keep repeating the movements of bending down to release the traction rope 22 and standing up to upwardly pull the traction rope 22, and the muscles of the waist, back, shoulders, arms and hands can be exercised.
[0057] Furthermore, it further includes footrests 24. One footrest 24 is respectively arranged below the parts of the first track 6 and the second track 7 that are exposed outside the housing 1. The first track 6 and the second track 7 are respectively slidably connected to the corresponding footrests 24, and the footrests 24 play a supporting role.
[0058] The technical effect achieved by this embodiment is that by setting the waist exercise mechanism, the muscles of the waist, back, shoulders, arms and hands can be exercised, and it has more uses.
[0059] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope claimed by the present invention.
[0060] Terms such as "up", "down", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope in which the present invention can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present invention can be implemented.
