Description

Technical Field

[0001] This invention relates to the field of paddling assistance technology, and in particular to a dragon boat paddling assistance device suitable for beginners. Background Technology

[0002] Dragon boat racing is a traditional water sport. Beginners face many challenges in mastering paddling techniques. They often experience low paddling efficiency due to uneven force application or incorrect movement trajectories, and may even suffer muscle strains or joint injuries.

[0003] Traditional training relies on verbal instructions from coaches or video replays, making it difficult to provide beginners with immediate feedback for corrective movements, resulting in a long learning cycle. Currently, while some auxiliary devices for dragon boat paddling exist on the market, most focus on improving the performance of professional athletes, such as increasing paddle blade area and optimizing paddle shaft materials to enhance paddling efficiency. For beginners, these devices do not allow them to intuitively perceive whether their movements are correct, affecting training effectiveness; some auxiliary devices are complex in structure and expensive, making them difficult to widely apply in beginner training scenarios; and some devices restrict the flexibility of paddling movements during use, hindering the natural learning process of paddling techniques for beginners.

[0004] Therefore, developing a dragon boat paddling aid device that is specifically designed for beginners, can effectively assist them in perceiving whether their movements are standard, has a simple structure, and is cost-effective, has significant practical significance and application value. Summary of the Invention

[0005] To address the above problems, this invention proposes a dragon boat paddling aid device suitable for beginners. The technical solution used is as follows: A dragon boat paddling aid device suitable for beginners includes a fixed frame that can be mounted on the hull, a sleeve rod that is movably mounted on the fixed frame, a telescopic rod that is slidably mounted in the sleeve rod, a ferrule that is movably mounted on the telescopic rod and can be mounted on the paddle, a sleeve frame that is fixedly mounted on the fixed frame, an arc frame that is slidably mounted in the sleeve frame, a straight recording bar, and an arc recording bar. A straight grid plate is fixedly installed on the telescopic rod, and a straight mounting groove corresponding to the straight recording strip is provided below the straight grid plate; a tapping rod is slidably and elastically installed on the sleeve rod, which intermittently contacts the straight grid plate, and the tapping rod can leave a mark when it taps the straight recording strip; An arc-shaped grid plate is fixedly installed on the arc-shaped surface of the arc-shaped frame, and an arc-shaped mounting groove corresponding to the arc-shaped recording strip is provided on the inner side of the arc-shaped grid plate; a sliding block is slidably installed on the outer side of the arc-shaped grid plate; a second striking rod that is slidably and elastically installed on the sliding block and intermittently contacts the arc-shaped grid plate, and the second striking rod can leave a mark when it strikes the arc-shaped recording strip; The sliding block has a limiting groove corresponding to the sleeve rod, and the sleeve rod can enter the limiting groove.

[0006] Furthermore, a fixing knob is rotatably mounted on the fixing frame for fixing the fixing frame to the hull.

[0007] Furthermore, it also includes a connecting rod disposed between the telescopic rod and the ferrule; the sleeve rod is rotatably mounted on the fixed frame; the two ends of the connecting rod are rotatably connected to the telescopic rod and the ferrule, respectively.

[0008] Furthermore, a card strip is slidably mounted on the card sleeve; a connecting knob is rotatably mounted on the card sleeve, and a connecting hole corresponding to the connecting knob is provided on the card strip.

[0009] Furthermore, a limiting protrusion is fixedly installed on the card strip, and the card sleeve is provided with a plurality of limiting rods that can lock the limiting protrusion.

[0010] Furthermore, it also includes a limiting frame that is slidably and elastically mounted on a fixed frame; a mounting rod is fixedly mounted on the limiting frame; and a plurality of mounting holes are provided on the arc-shaped frame corresponding to the mounting rod.

[0011] Furthermore, the second striking rod is elastically mounted on the sliding block via a leaf spring.

[0012] Furthermore, it also includes a rope roll box and an anti-slip sticker; the body of the rope roll box is mounted on a fixed frame, and the rope end is fixedly connected to the anti-slip sticker.

[0013] Because the present invention adopts the above-described technical solution, the present invention has the following advantages: This invention is used to assist beginners in paddling training. When paddling, the first striking rod strikes the straight recording bar, and the second striking rod strikes the curved recording bar. After training, the range of motion is judged by observing the striking marks on the straight and curved recording bars, thereby determining whether the paddling action is standard and helping beginners learn the standard action.

[0014] This invention has a simple structure and low cost, and can be widely used in training scenarios for beginners.

[0015] The distance between the arc-shaped frame and the fixed frame of this invention can be adjusted to accommodate the actual body shape of beginner paddlers; the paddle and the fixed frame are connected with multiple degrees of freedom, which does not restrict the flexibility of paddle movements, and beginners can naturally master the standard paddle movements.

[0016] The anti-slip sticker of this invention is attached to the oar. When paddling, the hand holding the anti-slip sticker can prevent slipping when entering the water. Attached Figure Description
