Description

Technical Field

[0001] This invention relates to the field of sports training technology, specifically to a unidirectional arm strength training device for dragon boat training and its implementation method. Background Technology

[0002] Dragon boat racing demands extremely high levels of arm explosiveness and overall body coordination from athletes. Specialized land-based arm strength training equipment is a core component for athletes' daily preparation, standardizing paddling posture, and improving paddling power. Scientific dragon boat training equipment needs to incorporate multiple functions, including leg power adjustment, training intensity grading, and movement posture correction, to replicate the actual paddling power generation logic on water and ensure training effectiveness.

[0003] The prior art patent with publication number CN114748861B proposes a unidirectional arm strength training device for dragon boat training. This device can adjust the tilt angle of the foot support device to fully mobilize the leg's coordinated force and improve the explosive power of the arm paddling and the training stability.

[0004] However, this patented product still has significant shortcomings in actual training use. Its training pole relies on a wire device to complete the transmission connection with the rear training components. This connection method is cumbersome to operate. When athletes repeatedly perform paddling and stretching movements, the wire is very prone to twisting and tangling. The tangling of the wire not only greatly increases the stretching resistance, destroys the real paddling power feel, and interferes with the athlete's normal training rhythm, but also causes excessive friction in some areas of the wire, accelerates wire damage and aging, and increases the frequency of equipment maintenance. In severe cases of tangling, the wire may even get stuck and the training pole may not be able to spring back, interrupting the training process and affecting the continuity of training. The tangled wire also poses a safety hazard of pulling and bumping into the athlete. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a unidirectional arm strength training device for dragon boat training and its implementation method, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a unidirectional arm strength training device for dragon boat training, comprising a support, two square tubes mounted on the support, and a seat mounted between the two square tubes. A training component is provided on the side of the support along its longitudinal extension direction, and a paddleboard is placed on the other side of the support opposite to the training component. Both square tubes are equipped with foot pedals, and an adjustment component connected to the foot pedals is provided inside the square tubes to adjust the distance between the foot pedals and the seat.

[0007] Furthermore, the training component includes a box disposed on the side of the support, a guide rod is disposed inside the box and extending through it along its length, a sleeve located inside the box is fixed on the outside of the guide rod, a transmission plate is vertically disposed on the outside of the sleeve, and a toggle plate is disposed on the outside of the transmission plate and above the box. The training assembly also includes an elastic structure disposed on the outside of the guide rod.

[0008] Furthermore, the elastic structure includes a threaded groove formed on the outside of the guide rod and located on the front side of the housing, a locking block threadedly connected to the outside of the threaded groove, a spring assembled between the locking block and the housing, and a limit block provided at the other end of the guide rod and located on the rear side of the housing.

[0009] Furthermore, the spring is sleeved on the outside of the guide rod.

[0010] Furthermore, the top of the housing is provided with a sliding groove for the transmission plate to move back and forth.

[0011] Furthermore, the top of the actuating plate bends forward to form a bend.

[0012] Furthermore, the elastic structure also includes a horizontal plate disposed on the front side of the support, and at least two placement racks are disposed on the side of the horizontal plate away from the support, the at least two placement racks being used to place springs with different stiffness coefficients respectively.

[0013] Furthermore, a placement frame is provided on the other side of the support and on the side opposite to the training component, and the paddleboard is disposed inside the placement frame.

[0014] Furthermore, the adjusting assembly includes a screw rotatably connected inside the square tube via a bearing, and a handle is fitted at one end of the screw for driving the screw to rotate; The screw is threaded to a slider, which is slidably connected inside the square tube. A square groove is provided on the top of the square tube for the slider to slide forward and backward. The foot pedal is fixedly connected to the slider.

[0015] A method for implementing a unidirectional arm strength training device for dragon boat training, wherein the training device described in any one of the above-mentioned methods is implemented, comprising the following operational steps: S1: Based on the user's height and leg length, turn the operating handle on the outside of the square tube to drive the screw inside the square tube to rotate, causing the threaded slider to move back and forth along the inner wall of the square tube, and simultaneously adjust the position of the foot pedal at the top of the slider. By using the thread self-locking characteristic of the screw slider, the distance between the foot pedal and the seat is fixed. S2: Select a spring with the corresponding stiffness coefficient according to the training intensity requirements, put it on the outside of the guide rod of the training component, turn the locking block at the front end of the guide rod to adjust the initial pre-compression of the spring, and complete the preset training resistance. S3: The user sits on the seat between the two square tubes, with both feet on the foot pedals on both sides. Holding the paddleboard, the user pushes forward, so that the front end of the paddleboard touches and pushes the actuation plate of the training component. The thrust is transmitted to the guide rod through the transmission plate and sleeve, causing the guide rod to move forward along the axial direction of the box and compress the spring. The reverse resistance of the spring simulates the water resistance of paddling on water. When the user retracts the paddleboard and removes the thrust, the spring releases elastic potential energy to push the guide rod, transmission plate and actuation plate to automatically reset. The cycle is repeated to complete the arm strength training of paddling in the same direction in a dragon boat. S4: After training, put the paddleboard back into the storage rack on the side of the support, and sort and store the spare springs of different specifications in the storage rack on the front horizontal plate of the support.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This dragon boat training device and its implementation method abandon the wire transmission structure. The equipment adopts a rigid direct connection transmission of guide rod and sleeve, which completely eliminates the defects of entanglement and jamming. The resistance is uniform and stable throughout the paddling force, which restores the real feeling of dragging a paddle on the water. It will not cause additional resistance due to wire twisting, which will interfere with the training rhythm. It eliminates the safety hazards of wire jamming interrupting training and pulling and bumping athletes. It significantly reduces the friction loss of transmission components, extends the service life of the equipment, and reduces the frequency of daily maintenance.

[0017] 2. This dragon boat training device and its implementation method are equipped with a special spring storage rack, which supports quick replacement of springs of various specifications for graded training. Springs of different stiffnesses are stored in separate areas for easy access. Beginners, intermediate, and professional athletes can switch training resistance as needed. At the same time, the locking block can finely adjust the spring preload to achieve precise resistance adjustment. One set of equipment meets multiple training needs such as basic posture correction, explosive power improvement, and endurance training. The equipment has strong versatility.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 This embodiment presents a unidirectional arm strength training device for dragon boat training. Addressing the shortcomings of existing dragon boat training equipment, such as tangled wire transmissions, distorted feel, and safety hazards, this device employs a direct-drive structure with a guide rod 402 and spring 407, coupled with an adjustable foot pedal 6 and a multi-specification spring 407 replacement structure. This adapts to different athletes and varying intensities of land-based unidirectional paddling arm strength training. The device comprises a support frame 1, a square tube 2, a seat 3, a training component 4, a paddleboard 5, a foot pedal 6, an adjustment component 7, and a placement rack 8. The training component 4 internally includes a housing 401, a guide rod 402, a sleeve 403, a transmission plate 404, a lever plate 405, a locking block 406, a spring 407, a crossbar 408, and a placement rack 409. The adjustment component 7 includes a screw 701 and a slider 702.

[0022] The support frame 1 serves as the base for the entire machine. Two square tubes 2 are fixed parallel to each other on the top of the support frame 1. As the base for the entire machine, the support frame 1 provides a unified installation benchmark for the square tubes 2, seat 3, training components 4, and placement rack 8. All functional components are concentrated and fixed on the support frame 1 to ensure that the entire machine does not shift or shake during the training process, thereby improving the overall stability of the equipment.

[0023] Furthermore, a seat 3 is mounted between the two square tubes 2. The two parallel square tubes 2 respectively support a foot pedal 6 on one side and an adjustment component 7. The training component 4 is assembled along one side of the support 1. A placement rack 8 is set on the opposite side of the support 1. The placement rack 8 is fixed on the side opposite the support 1 and the training component 4, and the paddleboard 5 is placed inside for limited positioning. The paddleboard 5 can be quickly taken out and put back before and after training, avoiding random placement of the paddleboard 5, which would occupy space or be damaged by bumps. Foot pedals 6 are installed on the top of both square tubes 2. The foot pedals 6 are rigidly fixed to the slider 702. The slider 702 achieves stable forward and backward displacement with the help of the screw 701. The foot pedals 6 adjust their forward and backward positions in sync to adapt to athletes with different leg lengths, ensuring that the legs can fully coordinate their force during training and reproducing the real dragon boat's full-body coordinated force exertion mode. The adjustment component 7 is assembled inside the square tubes 2. The adjustment component 7 is connected to the foot pedal 6 through a transmission, which can freely adjust the forward and backward distance between the foot pedal 6 and the seat 3 to adapt to the leg placement distance of athletes of different heights.

[0024] In detail, the adjustment components 7 are all built into the square tube 2. The two ends of the square tube 2 are supported by screws 701 through bearings. The screws 701 are rotatably connected to the square tube 2 through bearings. One end of the screw 701 extends to the outside of the square tube 2 and is equipped with an operating handle. The screw 701 is threaded to match the slider 702. The threaded transmission structure between the screw 701 and the slider 702 has a self-locking effect. After adjustment, the foot pedal 6 will not move on its own due to the force of the legs and will always maintain the set distance. The slider 702 slides against the inner wall of the square tube 2. The top of the square tube 2 has a long square groove. The square groove at the top of the square tube 2 constrains the slider 702 to slide only in a straight line back and forth, preventing the foot pedal 6 from shifting left and right, ensuring the symmetrical support position of the two feet, and correcting the incorrect training posture of unilateral force exertion. The slider 702 extends upward through the groove and is fixedly connected to the bottom of the foot pedal 6. Rotating the handle can drive the screw 701 to rotate, causing the slider 702 and the foot pedal 6 to move back and forth synchronously, freely adjusting the distance between the foot pedal 6 and the seat 3.

[0025] More specifically, the training component 4 uses the housing 401 as the external protective carrier. The top of the housing 401 has a long groove for the transmission plate 404 to slide back and forth. The groove at the top of the housing 401 limits the transmission plate 404 to only make linear forward and backward displacement. Inside the housing 401, a guide rod 402 is arranged along its length. The guide rod 402 passes through the housing 401 and is rigidly connected to the sleeve 403. The sleeve 403, the transmission plate 404, and the actuation plate 405 form an integrated force transmission component. The thrust of the paddle 5 can be completely and directly transmitted to the guide rod 402. This eliminates the traditional wire transmission structure, avoids entanglement and torsion problems, and provides uniform and stable force resistance, truly restoring the feel of paddling resistance on water.

[0026] Furthermore, the outer wall of the guide rod 402 is fixed with a sleeve 403, which is vertically and outwardly fixed to the transmission plate 404. The upper end of the transmission plate 404 passes through a groove and is integrally connected to the actuating plate 405. The top of the actuating plate 405 is bent forward to form a bend. The bend increases the contact area with the paddle 5, so that the force is even when pushing the paddle 5 and it is not easy to slip or detach. The bend structure matches the pushing angle of the front end of the paddle, completely replicating the contact form of real paddling force application.

[0027] In addition, the guide rod 402 is equipped with an elastic structure on its outer side. A threaded groove is formed at the front of the guide rod 402, which engages with the locking block 406. Rotating the locking block 406 allows for fine-tuning of the initial preload of the spring 407, slightly refining the training resistance. The locking block 406 is threaded onto the outer side of the threaded groove. A spring 407 is fitted between the locking block 406 and the front face of the housing 401. The two ends of the spring 407 abut against the locking block 406 and the front face of the housing 401, respectively. When the athlete pushes the paddle forward, the spring 407 is compressed, generating continuous reverse resistance. When the paddle is pulled back, the elastic force causes the entire transmission component to automatically rebound, eliminating the need for manual reset and enhancing training continuity. The spring 407 is integrally fitted onto the outer wall of the guide rod 402. The guide rod 402 restricts the spring 407 to compress and rebound only axially, preventing lateral torsional deformation and ensuring a stable and continuous elastic force output. A limiting block is fixed at the rear end of the guide rod 402, preventing the guide rod 402 from sliding out of the housing 401 and preventing the transmission structure from detaching and failing.

[0028] A horizontal plate 408 is fixed to the front of the support 1. The horizontal plate 408 is fixed to the front of the support 1. Multiple sets of storage racks 409 on the outside are used to store springs 407 of different stiffnesses in different sections. Trainees can quickly disassemble and replace springs 407 as needed without the need for additional storage containers, which is convenient for graded strength training. At least two sets of storage racks 409 are installed on the outside of the horizontal plate 408. The storage racks 409 can be used to store spare springs 407 of different stiffness coefficients in different categories, which makes it easy for athletes to quickly replace elastic components according to training needs and realize graded adjustment of training intensity.

[0029] A method for implementing a unidirectional arm strength training device for dragon boat training, wherein the training device as described above is implemented, and includes the following operational steps: S1: Based on the user's height and leg length, rotate the operating handle on the outside of the square tube 2 to drive the screw 701 inside the square tube 2 to rotate, causing the threaded slider 702 to move back and forth along the inner wall of the square tube 2, and simultaneously adjust the position of the foot pedal 6 at the top of the slider 702. By using the thread self-locking characteristic of the screw slider, the distance between the foot pedal 6 and the seat 3 is fixed. S2: According to the training intensity requirements, select a spring 407 with the corresponding stiffness coefficient, put it on the outside of the guide rod 402 of the training component 4, turn the locking block 406 at the front end of the guide rod 402 to adjust the initial pre-compression of the spring 407, and complete the preset training resistance. S3: The user sits on the seat 3 between the two square tubes 2, with both feet on the foot pedals 6 on both sides. Holding the paddleboard 5, the user pushes forward, so that the front end of the paddleboard 5 touches and pushes the actuation plate 405 of the training component 4. The thrust is transmitted to the guide rod 402 through the transmission plate 404 and the sleeve 403. The guide rod 402 moves forward along the axial direction of the housing 401 and compresses the spring 407. The reverse resistance of the spring 407 simulates the water resistance of paddling on water. When the user retracts the paddleboard and removes the thrust, the spring 407 releases elastic potential energy to push the guide rod, transmission plate and actuation plate to automatically reset. The cycle is repeated to complete the arm strength training of paddling in the same direction in a dragon boat. S4: After training, put the paddleboard 5 back into the storage rack 8 on the side of the support 1, and store the spare springs of different specifications 407 in the storage rack 409 on the front horizontal plate 408 of the support 1.

[0030] Complete usage procedure: The athlete rotates the outer handle of the screw 701, which moves the slider 702 and foot pedal 6 forward and then fixes them; according to the training intensity, replace the spring 407 with the corresponding stiffness and lock the locking block 406; sit on the seat 3, step on the foot pedal 6 with both feet, hold the paddleboard 5 and press it forward against the actuation plate 405 to push the guide rod 402 to compress the spring 407, simulating the water resistance of paddling; after releasing the force, the spring 407 automatically pushes the transmission structure to reset, and the training is completed in a cycle; after the training is completed, the paddleboard 5 and the spare spring 407 are returned to their corresponding placement racks 8 and 409 respectively.
