Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a foldable magnetically controlled climbing machine. Background Technology

[0002] Hiking is a great aerobic exercise, but outdoor sports are greatly affected by geographical location and natural weather conditions. For example, hiking is not very convenient in bad weather such as rain, snow, or strong winds. With the increasing use of fitness equipment, there are many fitness machines on the market that allow you to do various exercises without leaving home. By simulating the movement trajectory of your feet when hiking, you can do similar exercises to achieve the purpose of exercising your body.

[0003] For example, Chinese utility model patent (CN209952121 U) discloses a mountaineering machine, which states: "Since the bearing of the transmission device is perpendicular to the plane formed by the inclined tracks, and the damping structure is arranged laterally parallel to the track running direction of the inclined tracks, it occupies little space at the bottom of the support device; in addition, the position of the foot pedals allows them to reach the maximum distance of travel displacement; third, when the transmission belt breaks, replacement is simple, requiring only a simple one-time wrapping of the transmission belt around the first pulley and the second pulley, without the need for multiple wrappings; fourth, since the transmission belt has better flexibility, the diameter of the matching first pulley and second pulley is smaller, and a greater damping effect can also be achieved."

[0004] In summary, the existing technology has the following technical problems: the support frame of the climbing machine is a one-piece design and cannot be folded, which leads to space occupation when not in use. Therefore, this application proposes a foldable magnetic control climbing machine to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0035] As described in the background section, the support frame of the climbing machine is a single piece and cannot be folded, which results in space occupation when not in use.

[0036] To solve this technical problem, this utility model provides a foldable magnetically controlled mountaineering machine, which is used to simulate mountaineering and achieve the purpose of physical exercise.

[0037] For details, please refer to Figures 1-5 The foldable magnetic climbing machine specifically includes:

[0038] The device body 1 has two pedal assemblies 2 movably connected to it. A support frame 3 is foldably provided at the lower part of one end of the device body 1, and a handrail 4 is foldably provided at the upper part of one end of the device body 1. A multi-functional panel 5 is fixedly connected to the top of the handrail 4.

[0039] The main body 1 of the device includes two pedal slide rails 6, which are arranged in parallel. Two pedal assemblies 2 are slidably connected to the two pedal slide rails 6 respectively. A mounting frame 8 is provided between the two pedal slide rails 6. The bottom of the two pedal slide rails 6 and the mounting frame 8 are fixedly connected by a bottom beam 7. The top of the two pedal slide rails 6 and the mounting frame 8 are fixedly connected by a top beam 9. A transmission mechanism 10 is provided at the lower part of the mounting frame 8. Both pedal assemblies 2 are connected to the transmission mechanism 10.

[0040] The main body 1 of the device also includes a protective shell 11. The pedal slide rail 6, bottom beam 7, mounting bracket 8, top beam 9, and transmission mechanism 10 are all located inside the protective shell 11. The two pedal assemblies 2 are located above the protective shell 11. The protective shell 11 has through slots at the positions corresponding to the two handle brackets 12.

[0041] The foldable magnetic climbing machine provided by this utility model has a foldable support frame 3 and handrail 4 structure design, which allows the support frame 3 and handrail 4 to be folded up when the device is not in use, thereby reducing the overall space occupied by the device. At the same time, the folded device is easy to store and carry, making the device more convenient.

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] Example 1:

[0044] Please refer to Figures 1-5 A foldable magnetically controlled climbing machine, comprising:

[0045] The device body 1 has two pedal assemblies 2 movably connected to it. A support frame 3 is foldably installed at the lower part of one end of the device body 1, and a handrail 4 is foldably installed at the upper part of one end of the device body 1. A multi-functional panel 5 is fixedly connected to the top of the handrail 4 for displaying exercise-related information.

[0046] The foldable support frame 3 and handrail 4 design allows the device to be folded up when not in use, thereby reducing the overall space occupied by the device. The folded device is easy to store and carry, making it more convenient.

[0047] Specifically, the main body 1 of the device includes two pedal slide rails 6, which are arranged in parallel. Two pedal assemblies 2 are slidably connected to the two pedal slide rails 6 respectively. A mounting frame 8 is provided between the two pedal slide rails 6. The bottom of the two pedal slide rails 6 and the mounting frame 8 are fixedly connected by a bottom beam 7, and the top of the two pedal slide rails 6 and the mounting frame 8 are fixedly connected by a top beam 9. A transmission mechanism 10 is provided at the lower part of the mounting frame 8, and both pedal assemblies 2 are connected to the transmission mechanism 10. The two pedal slide rails 6 support the two pedal assemblies 2, and since both pedal assemblies 2 are connected to the transmission mechanism 10, the two pedal assemblies 2 are stepped on alternately, and the resistance generated by the transmission mechanism 10 achieves the effect of movement.

[0048] Specifically, the main body 1 of the device also includes a protective shell 11. The pedal slide rail 6, bottom beam 7, mounting bracket 8, top beam 9, and transmission mechanism 10 are all located inside the protective shell 11. The two pedal assemblies 2 are located above the protective shell 11. The protective shell 11 has through slots at the positions corresponding to the two handle brackets 12. The protective shell 11 protects the pedal slide rail 6, bottom beam 7, mounting bracket 8, top beam 9, and transmission mechanism 10.

[0049] Furthermore, the transmission mechanism 10 includes a first transmission wheel 13, a second transmission wheel 14, and a transmission wheel set 16. The first transmission wheel 13 is rotatably connected to the mounting frame 8, the second transmission wheel 14 is rotatably connected to the top beam 9, and the transmission wheel set 16 is connected to the bottom beam 7. The first transmission wheel 13 and the transmission wheel set 16 are connected by a pedal linkage belt 17, and the second transmission wheel 14 and the transmission wheel set 16 are connected by a damping transmission belt 18. A magnetic control disk 15 is fixedly connected to one end of the second transmission wheel 14 away from the mounting frame 8. A fixed magnet seat is provided on one side of the magnetic control disk 15, and an external magnetic adjuster 20 is provided on the other side of the magnetic control disk 15. Both the fixed magnet seat and the external magnetic adjuster 20 are fixedly connected to the top beam 9. Both pedal assemblies 2 are connected to both sides of the pedal linkage belt 17 respectively through connecting buckles 19.

[0050] The transmission wheel assembly 16 includes a hook frame 21, on which a third transmission wheel 22 is detachably and rotatably connected. The pedal linkage belt 17 and the damping transmission belt 18 are both connected to the third transmission wheel 22. The hook frame 21 and the bottom beam 7 are detachably and fixedly connected by an adjustable bolt 23.

[0051] As can be seen, when one pedal assembly 2 moves down, the other pedal assembly 2 moves up, causing the pedal linkage belt 17 to move. The movement of the pedal linkage belt 17, through the transmission of the third transmission wheel 22, synchronously drives the damping transmission belt 18 to rotate, and through the second transmission wheel 14, drives the magnetic control disk 15 to rotate, thereby generating resistance. By adjusting the distance between the external magnetic adjuster 20 and the magnetic control disk 15, resistance is generated, thereby achieving adjustable resistance.

[0052] Furthermore, to facilitate the handling and movement of the device, a stable base 25 is fixedly connected to the lower end of the bottom beam 7, and a movable wheel frame 24 is fixedly connected to the side of the bottom beam 7. The main body 1 of the device also includes a handle frame 12, which is fixedly connected to the end of the top beam 9 away from the mounting frame 8, and extends to the outside of the protective shell 11. It can be seen that when the device is unfolded, the stability of the device during use is ensured by the contact between the stable base 25 and the ground. When the device is folded, the device can be moved by lifting it with the handle frame 12, so that the movable wheel frame 24 at the other end of the device contacts the ground, thereby making the movement of the device easier.

[0053] Example 2:

[0054] The foldable magnetic climbing machine provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown, both ends of the top beam 9 are fixedly connected to rotating limiting plates 26. The lower end of the handrail 4 is rotatably connected to the rotating limiting plate 26. The end of the handrail 4 near the rotating limiting plate 26 is laterally connected to a limiting bolt 27. The limiting bolt 27 is inserted into the rotating limiting plate 26. The rotating limiting plate 26 is provided with an unfolding positioning hole and a folding positioning hole.

[0055] Through the above structural design, the handrail 4 can be folded by rotating the handrail 4 and the rotating limiting plate 26. The handrail 4 can be rotated and limited after being unfolded or folded by inserting the limiting bolt 27 into the unfolding positioning hole and the folding positioning hole on the rotating limiting plate 26.

[0056] Example 3:

[0057] The foldable magnetic climbing machine provided in Example 1 has been further optimized, specifically, as follows: Figures 7-9 As shown, the upper end of the support frame 3 is rotatably connected to a rotation limit frame 29. The rotation limit frame 29 is fixedly connected to the pedal slide rail 6 on the same side through a connecting bracket 28. A limit rod 30 is provided on the inner side of the support frame 3. The two ends of the limit rod 30 are slidably connected to the two rotation limit frames 29 respectively. The limit rod 30 is used to limit the rotation of the support frame 3.

[0058] Furthermore, the rotating limiting frame 29 is provided with a movable through groove 31. One end of the movable through groove 31 is provided with multiple unfolding adjustment holes 32, and the other end of the movable through groove 31 is provided with a folding limiting hole 33. Both ends of the limiting rod 30 are provided with limiting blocks 34. The limiting blocks 34 are slidably connected to the movable through groove 31. The limiting blocks 34 are plugged into the unfolding adjustment holes 32 and the folding limiting holes 33.

[0059] A connecting cylinder 35 is fixedly connected to the handrail 4 at a position corresponding to the rotating limiting frame 29. The limiting rod 30 is slidably connected to the connecting cylinder 35. A pull handle 37 is fixedly connected to one end of the limiting rod 30. A return spring 36 is sleeved on the other end of the limiting rod 30. The return spring 36 is located inside the connecting cylinder 35 at the same end. One end of the return spring 36 is in contact with the inside of the connecting cylinder 35, and the other end of the return spring 36 is in contact with the end of the limiting block 34.

[0060] It can be seen that the support frame 3 can be folded through the rotational connection between the support frame 3 and the rotating limiting frame 29. The limiting rod 30 is inserted into the unfolding adjustment hole 32 at different positions through the limiting block 34, which can realize the effect of adjusting the unfolding angle of the support frame 3. After the support frame 3 is folded, the limiting rod 30 is inserted into the folding limiting hole 33 through the limiting block 34 to realize the limiting effect of the support frame 3 after folding. Among them, by pulling the handle 37 at one end of the limiting rod 30, the limiting block 34 at the end of the limiting rod 30 can be separated from the unfolding adjustment hole 32 and the folding limiting hole 33, so that the end of the limiting block 34 can slide inside the movable through groove 31. Meanwhile, during the movement of the limiting rod 30, the limiting block 34 presses against the reset spring 36, causing the reset spring 36 to accumulate force. When the pull handle 37 is released, the reset spring 36 releases the stored force, which can push the limiting block 34 to reset, so that the limiting block 34 can reconnect with the unfolding adjustment hole 32 and the folding limiting hole 33 and maintain the connection state.
