Description

Technical Field

[0001] The present application relates to the technical field of sports equipment, and in particular to a running resistance trainer. Background Art

[0002] During running, people often use resistance training devices to improve their exercise efficiency and physical fitness, mainly by increasing the resistance during exercise to enhance muscle strength, endurance and cardiopulmonary capacity. Existing resistance training devices often use elastic ropes. Although they are portable, they require two people to use them together, and the resistance is achieved by the second person who drags them. Therefore, there is an urgent need for a device that can replace the second person to perform resistance training and has an effective damping effect. In addition, other conventional resistance training devices are large in size, which is not conducive to portable use outdoors. Therefore, the device also needs to be miniaturized and easy to carry. Utility Model Content

[0003] The present invention provides a running resistance training device, and the specific implementation is as follows:

[0004] A running resistance training device, comprising:

[0005] A housing with a pull rope built in, the pull rope is wound through a pay-off drum and arranged in the housing, and a one-way buffer component and a reset structure are arranged between the housing and the pay-off drum, the end of the pull rope is connected to the moving part of the human body, and the one-way buffer component provides a buffering effect when the pull rope is released;

[0006] The one-way buffer assembly includes a needle roller clutch, a fixed ring body and a first rotating ring body that are rotatably connected. The input end of the needle roller clutch is engaged with the wire pay-off disk, and the output end of the needle roller clutch is connected to the first rotating ring body. A damping is provided between the first rotating ring body and the fixed ring body.

[0007] Based on the above technical solutions, in the design of sports training equipment, the pull rope is given impact performance by integrating the needle clutch and the damping force. When the athlete pulls the pull rope, the gear damping system will generate a moderate damping force. This force simulates the running resistance or the running weight resistance, bringing a continuous and real sense of confrontation to the runner.

[0008] Preferably, a receiving chamber for accommodating a wire pay-off drum, a one-way buffer assembly and a reset structure is provided on the inner side of the shell, a fixed shaft is provided at the center of the receiving chamber, a wire pay-off drum is sleeved on the outer side of the fixed shaft, and a clockwork spring is provided between the two.

[0009] Based on the above technical solution, when the external pulling force is removed, that is, the movement stops, the built-in clockwork spring immediately exerts its properties, spontaneously generates a restoring force, and drives the pay-off drum to slide back to its original position, thereby automatically retracting the pull rope. It not only simplifies the operation process and reduces the burden on athletes or users, without the tedious manual resetting of the rope, but also improves the continuity and fluency of the entire training or use.

[0010] Preferably, the damping effect between the first rotating ring body and the fixed ring body can be arranged in two forms, namely:

[0011] Firstly, the outer circumferential surface of the first rotating ring body and the inner circumferential surface of the fixed ring body are both arranged as friction surfaces, and the two are in contact with each other.

[0012] Secondly, the first rotating ring body is provided with a plurality of second magnetic sheets equidistantly along its outer circumference, the fixed ring body is provided with a plurality of first magnetic sheets having opposite magnetic properties to the second magnetic sheets on its inner circumference, and the first rotating ring body and the fixed ring body are gap-fitted.

[0013] Preferably, the output end of the needle clutch is configured as a second rotating ring body, an outer side of which is provided with a recessed portion, and the second rotating ring body is integrally connected with the raised portion of the first rotating ring body via the recessed portion.

[0014] Preferably, the pay-off drum is provided with an outward gear ring, and the input end of the needle clutch is provided with a driven gear meshing with the outward gear ring.

[0015] Based on the above technical scheme, the synchronous circumferential rotation between the second rotating ring body and the first rotating ring body can be achieved through the recessed portion and the raised portion; the needle roller clutch is specifically a conventional existing structure composed of an inclined block, an integral shaft and a needle roller. As a precision transmission mechanical component, it has the characteristic of one-way power transmission, and only allows engagement in one direction and free sliding in the other direction. It is suitable for one-way braking or locking mechanism.

[0016] Preferably, the accommodating cavity is in a single-side conductive shape, and a side sealing plate is installed on the conductive side, and a detachable positioning rope is integrated on the side sealing plate.

[0017] Preferably, the side sealing plate includes a seat body, the seat body is provided with an annular groove along its circumference, and a limit pin is arranged in the annular groove; second lock buckles are arranged at both ends of the positioning rope, and the positioning rope is buckled on the limit pin through the second lock buckle.

[0018] Based on the above technical solution, the positioning rope can be quickly fixed on the side cover plate through the second lock buckle, and the positioning rope can be tied to fixed objects on the sports field, such as railings, ladders, etc.; when the second lock buckle is idle, it can be wrapped around the annular groove to achieve hidden storage.

[0019] Preferably, the end of the first lock buckle can be connected to different parts of the human body, such as the waist, legs, wrists and arms. There are two specific implementation structures, namely:

[0020] Firstly, the first lock buckle is detachably connected to the wrist fixing belt via a positioning ring.

[0021] Secondly, the first lock buckle is detachably connected to the waist fixing belt.

[0022] Based on the above technical solution, the positioning rope can be quickly fixed on the side cover plate through the second lock buckle, and the positioning rope can be tied to fixed objects on the sports field, such as railings, ladders, etc.; when the second lock buckle is idle, it can be wrapped around the annular groove to achieve hidden storage.
