Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically to a sports training tension device with adjustable resistance. Background Technology

[0002] Sports training equipment refers to various tools and equipment used in the process of sports training to help trainees improve their physical fitness, enhance their athletic skills, and improve their competitive level.

[0003] An existing patent (publication number: CN213252782U) discloses a tension device for sports training, including an elastic rope, a connecting block, a snap-fit ​​post, and a connecting strap. The elastic rope has mounting structures on both sides. A snap-fit ​​post is fixedly connected to one end of the connecting block. A connecting strap is fixedly connected to both the top and bottom ends of the connecting block, and a fixing plate is fixedly connected to the outer wall of the connecting strap. A gripping structure is provided on the inner wall of the connecting strap. This invention, by incorporating a connecting block, a limiting block, a fixing bolt, a nut, and a rubber ring, strengthens the connection between the connecting block and the elastic rope by fitting the connecting block onto the outer wall of the elastic rope. The fixing bolt penetrates the interior of the connecting block, and the fixing bolt and nut are threaded together. Combined with the limiting block, the connecting block can be clamped and fixed. Simultaneously, a rubber ring is fitted on the outer wall of the fixing bolt. When the rubber ring is compressed, it contracts inward and expands, further strengthening the fixation to the connecting block, thus facilitating installation.

[0004] When the above-mentioned tension device is in use, the tension rope and the two handles are fixedly connected as one unit. This makes it impossible for the user to flexibly adjust the tension level. In actual training, it is difficult for the user to accurately adjust the resistance level during training according to their current needs. As the user gradually adapts to the tension provided by the current equipment, they often need to replace it with training equipment with stronger resistance. This not only increases training costs but also brings many inconveniences. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable resistance sports training tension device, which has advantages such as resistance adjustment and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable resistance sports training tension device, comprising a left handle and a right handle, with multiple tension ropes disposed between the left and right handles, and an adjustment assembly disposed inside the left and right handles, the adjustment assembly comprising a winding rod rotatably connected to the inner wall of the left handle, the left end of each tension rope being fixedly connected to the winding rod, a rotating rod rotatably connected to the inner wall of the right handle, an adjustment ring fixedly connected to the outer surface of the rotating rod, a rotating disk fixedly connected to the left end of the rotating rod, and the right ends of the multiple tension ropes being connected to the left side of the rotating disk by a snap fastener.

[0007] With the above solution, the left adjustment component can pre-wind the tension rope via the left handle, shortening the length of the tension rope, and can also adjust the degree of winding of the tension rope.

[0008] Furthermore, the upper end of the winding rod is diamond-shaped, a card frame is fixedly connected to the upper surface of the left handle, a card cap is slidably inserted into the inside of the card frame, the upper end of the diamond-shaped winding rod is slidably inserted into the inner wall of the card cap, and a spring is fixedly connected between the upper end of the diamond-shaped winding rod and the inner wall of the card cap.

[0009] By using the above solution, the engagement of the locking cap with the diamond-shaped extension at the upper end of the winding rod can lock the winding rod, preventing it from rotating due to tension during the stretching process and causing instability in the tension rope.

[0010] Furthermore, a damping bearing is installed on the inner wall of the right handle, and the right end of the rotating rod is interference-fitted with the damping bearing.

[0011] By implementing the above solution, the damping bearing allows the rotating rod to slowly reset under the force of the tension ropes when the user resets multiple tension ropes, thus preventing the tension ropes from suddenly resetting and causing injury to the user.

[0012] Furthermore, a set of circumferentially distributed limiting blocks are fixedly connected to the right side of the adjusting ring inside the right handle. Each of the limiting blocks is chamfered. A limiting toothed disc is slidably connected to the outer surface of the rotating rod, and the limiting toothed disc contacts each limiting block.

[0013] The above scheme, which sets up the cooperation between the limiting gear and the limiting block, can limit the multiple tension ropes while the user twists them together stably through the adjusting ring, thus preventing the multiple tension ropes from being dispersed due to the deformation force.

[0014] Furthermore, a second spring is fixedly connected to the right side of the limiting gear plate, and the other end of the second spring is fixedly connected to the inner wall of the right handle. The second spring is initially in a compressed state.

[0015] With the above scheme, the spring is designed to push the limiting gear plate to always be in contact with the right adjustment ring through the deformation force of the spring, and cooperate with the limiting block to limit the right adjustment ring.

[0016] Furthermore, a groove is provided on the upper surface of the right handle, and a lever is slidably connected inside the groove. The bottom end of the lever is fixedly connected to the outer circumferential surface of the limiting gear plate.

[0017] The above scheme allows the user to easily contact the limit of the right adjustment ring by sliding the toggle block, so that the rotating rod can rotate in the opposite direction under the action of the tension rope deformation force, and with the help of the damping bearing, the multiple tension ropes can be slowly reset.

[0018] Furthermore, pads are fixedly connected to the inner walls of both the left and right handles, and each pad is made of rubber.

[0019] The above solution allows for the spacing of multiple pads between the user's fingers. The pads are made of rubber, which is flexible and prevents the user's fingers from bunching together and causing discomfort when they exert force.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This adjustable resistance sports training tension device uses a winding rod to pre-wind the tension ropes, shortening their length and allowing adjustment of the winding degree. A shorter rope means muscles need to contract in a shorter time, increasing training resistance. The rotating rod twists multiple ropes together, creating an intertwined, unified force structure. Under external force, the ropes constrain and deform collaboratively, not only maximizing their load-bearing capacity but also generating significant friction between them. When external force attempts to lengthen them, this friction hinders relative sliding, further increasing overall training difficulty. This combined effect allows for precise adjustment of the resistance experienced by the user during tension training, tailored to their specific needs. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figures 1-7This embodiment of an adjustable resistance sports training tension device includes a left handle 1 and a right handle 2. Multiple tension ropes 3 are disposed between the left handle 1 and the right handle 2. An adjustment assembly 4 is disposed inside the left handle 1 and the right handle 2. The adjustment assembly 4 includes a winding rod 401 rotatably connected to the inner wall of the left handle 1. The left end of each tension rope 3 is fixedly connected to the winding rod 401. A rotating rod 402 is rotatably connected to the inner wall of the right handle 2. An adjustment ring 404 is fixedly connected to the outer surface of the rotating rod 402. A rotating disk 403 is fixedly connected to the left end of the rotating rod 402. The right ends of the multiple tension ropes 3 are connected to the left side of the rotating disk 403 via snap-fit ​​connections. The winding rod 401 can pre-wind the tension ropes 3, shortening their length. The resistance bands 3 mean that the muscles need to complete the contraction action in a shorter time, thereby increasing the resistance of the training. The rotating lever 402 of the right handle 2 can twist multiple resistance bands 3 together, so that the multiple resistance bands 3 are intertwined and interwoven to form an integrated force structure. Under the action of external force, the resistance bands 3 will restrain each other and deform in coordination, not only exerting their own load-bearing capacity, but also having a large friction between the twisted resistance bands 3. When the external force tries to stretch them, this friction will also hinder the relative sliding of the resistance bands 3, further increasing the overall training difficulty. The cooperation of the two can accurately adjust the resistance experienced by the user during resistance training, thereby being able to meet the specific needs of the user.

[0036] The upper end of the winding rod 401 is diamond-shaped. A retaining frame 5 is fixedly connected to the upper surface of the left handle 1. A retaining cap 6 is slidably inserted into the inside of the retaining frame 5. The upper end of the diamond-shaped winding rod 401 is slidably inserted into the inner wall of the retaining cap 6. A spring 7 is fixedly connected between the upper end of the diamond-shaped winding rod 401 and the inner wall of the retaining cap 6. The engagement between the retaining cap 6 and the diamond-shaped extension at the upper end of the winding rod 401 locks the winding rod 401, preventing the winding rod 401 from rotating due to the tension during the stretching process, thus avoiding instability of the tension rope 3. A damping bearing 8 is installed on the inner wall of the right handle 2. The right end of the rotating rod 402 is interference-fitted with the damping bearing 8. The damping bearing 8 allows the rotating rod 402 to slowly reset under the force of the tension rope 3 when the user resets multiple tension ropes 3, preventing sudden reset of the tension rope 3 from causing injury to the user.

[0037] A set of circumferentially distributed limiting blocks 9 are fixedly connected to the right side of the adjusting ring 5 inside the right handle 2. Each limiting block 9 is chamfered. A limiting gear 10 is slidably connected to the outer surface of the rotating rod 402. The limiting gear 10 contacts each limiting block 9. The cooperation between the limiting gear 10 and the limiting block 9 can limit the multiple tension ropes 3 while the user twists them together stably through the adjusting ring 404, preventing the multiple tension ropes 3 from being dispersed due to deformation force. A spring 9 is fixedly connected to the right side of the limiting gear 10. The other end of the spring 9 is fixedly connected to the inner wall of the right handle 2. The spring 9 is in a compressed state in the initial state. In this way, the deformation force of the spring 9 pushes the limiting gear 8 to always contact the adjusting ring 5, and cooperates with the limiting block 7 to limit the adjusting ring 5.

[0038] The upper surface of the right handle 2 is provided with a groove 12, and a lever 13 is slidably connected inside the groove 12. The bottom end of the lever 13 is fixedly connected to the outer circumferential surface of the limiting gear plate 10. The lever 13 allows the user to contact the limiting of the right adjustment ring 404 by sliding the lever 13, so that the rotating rod 402 can rotate in the opposite direction under the deformation force of the tension rope 3. With the help of the damping bearing 8, the multiple tension ropes 3 can be slowly reset. The inner walls of the left handle 1 and the right handle 2 are fixedly connected with pads 14. Each pad 14 is made of rubber. The multiple pads 14 can separate the user's multiple fingers. The pads 14 are made of rubber and are flexible, which can prevent the user's fingers from piling up together and causing discomfort.

[0039] It should be noted that when the bearing is running, the internal damping elements, such as special viscous media and elastic damping materials, will generate a force opposite to the direction of motion. This force will consume the energy generated by the bearing's motion, thereby playing the role of buffering, vibration reduction and speed reduction.

[0040] Each tooth on the side of the limiting toothed disc 8 is a triangular tooth.

[0041] The working principle of the above embodiment is as follows: First, before training, the user removes the cap 6, separating it from the frame 5, but maintaining contact between the cap 6 and the upper diamond-shaped protrusion of the winding rod 401. Then, the user rotates the cap 6, causing it to rotate through the diamond-shaped protrusion and wind up the left end of the resistance band 3, thus shortening its length. A shorter resistance band means the muscles need to complete the contraction action in a shorter time, increasing training resistance. During training, the user can rotate the rotating rod 402 by moving the right adjustment ring 404. During the process, the right ends of multiple tension ropes 3 can be twisted in the direction of rotation of the rotating disk 403 via the rotating disk 403, so that the multiple tension ropes 3 can be twisted together. Similarly, the degree of twisting of the tension ropes 3 is adjusted according to the number of rotations of the right adjustment ring 404. When the multiple tension ropes 3 are twisted together, they can form an integral force structure through intertwining and weaving. Under the action of external force, the tension ropes 3 will restrain each other and deform together, which not only can exert their own load-bearing capacity, but also there is a large friction between the twisted tension ropes 3, thereby increasing the training difficulty. The controllable resistance adjustment can adjust the training difficulty according to the specific needs of the user.
