Problems solved by technology

Existing dragon boat paddles are all integrally formed, resulting in excessive thickness at the connection between the blade and the paddle shaft. Considering that the shape of the paddle shaft is cylindrical, and the paddle is flat, the blade is hollow, which is not conducive to Lightweight dragon boat paddles. The existing dragon boat paddles have a hollow structure, resulting in a thinner side of the blade and poor durability.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1-Figure 3 and Figure 5 The paddle used for a new type of dragon boat competition shown includes a paddle handle 1, a paddle shaft 2 and a paddle blade 3, the paddle shaft 2 is cylindrical, one end of the paddle shaft 2 is connected to the paddle handle 1, and the other end is connected to the paddle The paddles 3 are connected, and the paddles 3 are solid sheets with a small top and a large bottom. The paddles 3 are made solid, which can reduce the thickness of the paddles 3, reduce buoyancy, and consume less to the athletes during use. 3 A protrusion 4 is provided near the upper edge for connecting with the paddle shaft 2, the upper part of the protrusion 4 is cylindrical, and the lower part gradually shrinks to reduce the resistance when entering the water, and the back of the paddle 3 is provided with at least A ra...

Abstract

The invention discloses a novel paddle for dragon boat racing, Including shank, rods and blades, the paddle rod is cylindrical, one end of the rod is connected to the shank, the other end of which isconnected to the blade, the paddle blade is in the shape of a solid sheet with a small upper and a large lower part, At least one convex water dividing line is arrange at that center of the back surface of the blade, and the water dividing line is vertically arrange. The upper ends of the blades are two rounded corners of the blade, and the radius of the rounded corners at the shoulders is 1-6 cm,and that two fillet at the lower end of the blade are rotor root, and the radius of the fillet at the rotor root is 0.5-6 cm, and that back surface of the blade is slightly inwardly concave into a micro-spherical surface or an arc surface. The oar has the advantages of small water entry resistance, good water grasping effect, high power performance and reduced physical power consumption when theutility model is used.

Description

technical field [0001] The invention belongs to the technical field of dragon boat racing appliances, in particular to a novel paddle for dragon boat racing. Background technique [0002] Dragon boat racing is one of the customs of the Dragon Boat Festival in China, and it is also one of the most important festival folk activities of the Dragon Boat Festival. It is common in southern China, and there are also dragon boat racing customs in cities near rivers and lakes in the north. Dragon boat races must use oars, and most of the existing oars are made of modern new materials. Existing dragon boat paddles are all integrally formed, resulting in excessive thickness at the connection between the blade and the paddle shaft. Considering that the shape of the paddle shaft is cylindrical, and the paddle is flat, the blade is hollow, which is not conducive to The lightweight of the dragon boat paddle, because the existing dragon boat paddle is a hollow structure, the thickness of t...
