Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically referring to a non-powered treadmill with multiple resistance adjustment methods. Background Technology

[0002] Traditional treadmills are driven by motors, resulting in complex structures and high maintenance costs. In contrast, non-motorized treadmills propel the user's footsteps, allowing for speed control. They require no electricity, making them more energy-efficient and environmentally friendly. Furthermore, their curved design helps correct running posture and can generate acceleration and deceleration effects through the curvature, thus helping to adjust running posture and reduce sports injuries.

[0003] Existing non-powered treadmills, such as the electromagnetic damping non-powered intelligent treadmill disclosed in application number 201822100359.2, use a damping mechanism composed of an electromagnetic damping device and a damping amplification transmission device to make the range of resistance adjustment very large, and can greatly reduce the size of the entire damping mechanism and the power consumption.

[0004] However, in actual use, the resistance is adjusted solely by the electromagnetic damping device, which has a limited adjustment method and cannot be used when the power is off, limiting its applicability to specific situations. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a non-powered treadmill with multiple resistance adjustment methods, which effectively solves the problems of the current non-powered treadmills having a single resistance adjustment mode and being inconvenient to use in the event of a power outage.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a non-powered treadmill with multiple resistance adjustment methods, including a frame body. Shells are fixed to both sides of the frame body, and a handrail is fixed to the outer side of the connection between the frame body and the shells. A front wheel axle is rotatably connected to the frame body inside the shells, and a fixed crossbar is fixed to the inner wall of the frame body on one side of the front wheel axle. A mechanical friction adjustment mechanism is provided between the front wheel axle and the fixed crossbar. The mechanical friction adjustment mechanism includes a guide plate fixed to the middle of the upper end of the fixed crossbar, a guide rod inserted and pulled onto the guide plate, a friction wheel fixed to the middle of the front wheel axle, a friction belt fixed to the fixed crossbar, and the other end of the friction belt passing around the bottom of the friction wheel and connected to the guide rod via a spring. A fine-tuning handle is provided at the upper end of the inner side of the handrail, and a steel wire rope is wound around the fine-tuning handle, with the other end of the steel wire rope passing through the upright of the handrail and connected to the guide rod inside the shell.

[0007] As an improvement to this solution, the front axle is fixed with front wheel supports at both ends, and the rear axle is rotatably connected to one end of the frame body that is symmetrical to the front axle, with rear wheel supports fixed at both ends of the rear axle.

[0008] As an improvement to this solution, running belts are fitted onto the front and rear supporting wheels, and running plates are evenly distributed along the contour of the running belts.

[0009] As an improvement to this solution, a frame is fixed on the fixed crossbar on the inner wall of the main frame, and several support wheels are evenly distributed on the frame, with the upper end of the support wheel fitting against the top of the inner side of the running belt.

[0010] As an improvement to this solution, magnetic resistance connecting shafts are rotatably connected to both sides of the lower middle part of the frame body. Anti-slip wheels that fit against the support wheels are fixed at both ends of the magnetic resistance connecting shafts, and the ends of the magnetic resistance connecting shafts penetrate the frame body for connection with external magnetic damping mechanisms.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. It features multiple adjustment modes, including magnetic and mechanical friction adjustment, allowing the non-powered treadmill to be used in various situations and making it suitable for a wide range of occasions;

[0013] 2. The mechanical friction adjustment mechanism adopted is stable and reliable. It achieves resistance adjustment by changing the contact pressure between the friction wheel and the friction belt. It can be infinitely adjusted by simply moving the fine adjuster handle with your finger. It is simple to operate and the adjustment is smooth. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a non-powered treadmill with multiple resistance adjustment methods, including a frame body 1, outer shells 2 fixed on both sides of the frame body 1, and a handrail frame 3 fixed on the outer side of the connection between the frame body 1 and the outer shell 2. A front wheel axle 4 is rotatably connected to the frame body 1 on the inner side of the outer shell 2, and a fixed crossbar 5 is fixed on the inner wall of the frame body 1 on one side of the front wheel axle 4. A mechanical friction adjustment mechanism 6 is provided between the front wheel axle 4 and the fixed crossbar 5.

[0022] The mechanical friction adjustment mechanism 6 can adjust the resistance when the front wheel axle 4 rotates, thereby increasing the amount of energy consumed during running.

[0023] like Figure 3 As shown, in order to adjust the resistance when the front wheel axle 4 rotates, the mechanical friction adjustment mechanism 6 includes a guide plate 7 fixed to the middle of the upper end of the fixed crossbar 5, a guide rod 10 inserted and pulled on the guide plate 7, a friction wheel 8 fixed in the middle of the front wheel axle 4, a friction belt 9 fixed on the fixed crossbar 5, and the other end of the friction belt 9 passes around the bottom of the friction wheel 8 and is connected to the guide rod 10 through a spring 11.

[0024] like Figure 1 As shown, the upper end of the inner side of the handrail 3 is provided with a fine-tuning handle 12, and a steel wire rope 13 is wound around the fine-tuning handle 12. The other end of the steel wire rope 13 passes through the upright of the handrail 3 and is connected to the guide rod 10 inside the outer shell 2.

[0025] The front axle 4 has front wheels 14 fixed at both ends, and a rear axle 15 is rotatably connected to one end of the frame body 1 that is symmetrical to the front axle 4. The rear wheels 16 are fixed at both ends of the rear axle 15.

[0026] Running belts 17 are fitted onto the front wheel 14 and the rear wheel 16, and running plates 18 are evenly distributed along the contour of the running belts 17.

[0027] A frame 19 is fixed on a fixed crossbar 5 on the inner wall of the frame body 1. Several support wheels 20 are evenly distributed on the frame 19, and the upper end of the support wheel 20 is in contact with the top of the inner side of the running belt 17.

[0028] The lower middle part of the frame body 1 is rotatably connected to two sides of a magnetic resistance connecting shaft 21. The two ends of the magnetic resistance connecting shaft 21 are fixed with anti-slip wheels that fit against the support wheel 20. The end of the magnetic resistance connecting shaft 21 passes through the frame body 1 and is used to connect with an external magnetic damping mechanism.

[0029] In practical use, the user stands on the running board 18 and adjusts its position on the main frame 1. This allows the treadmill's curvature, under the influence of gravity and human effort, to drive the running belt 17 to slide under the support of the support wheels 20, thus rotating the front support wheels 14 and the rear support wheels 16 at both ends. When resistance needs adjustment, simply move the fine-tuning handle 12 to wind the steel cable 13 around it. This causes the other end of the steel cable 13 to pull the guide rod 10 along a direction perpendicular to the guide plate 7 towards the rear wheel axle 15, thereby causing the friction belt 9 to move along the guide rod 10. The hand 12 pulls the friction wheel 8 more tightly, and the friction between the friction wheel 8 and the friction belt 9 can prevent the front wheel axle 4, which is fixedly connected to the friction belt 9, from rotating. In turn, the support front wheels 14 on both sides of the front wheel axle 4 prevent the running belt 17 from sliding, thereby increasing the resistance. In addition, by connecting the magnetic resistance connecting shaft 21 to the existing external magnetic resistance mechanism, the anti-slip wheels at both ends of the magnetic resistance connecting shaft 21 can also prevent the support wheel 20 from rotating, thereby preventing the running belt 17 from sliding and increasing the resistance. The above is the entire process of using the non-powered treadmill with multiple resistance adjustment methods.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
