Description

Technical Field

[0001] The utility model relates to the technical field of boat oars, in particular to a plastic dragon boat oar. Background Art

[0002] Dragon boat racing is a traditional water sport in China and East Asia, especially in China, where it has a long history and profound cultural heritage. The main tools for dragon boat racing are dragon boats and dragon boat paddles. Existing dragon boat paddles are generally made of wood, carbon fiber, fiberglass, and alloy materials. The production cost of these materials is high, and the production is locked. In addition, the dragon boat paddles are very heavy. During the long paddling process, the athletes' physical strength is quickly consumed. Moreover, once wood, carbon fiber, fiberglass, and alloy materials collide and break, they are likely to cause harm to the athletes. At the same time, fiberglass is a material that cannot be decomposed and has a great impact on the ecology. If other lighter materials are used, the dragon boat paddles are not strong enough and are prone to breakage during use, affecting the competition. For this reason, plastic dragon boat paddles are proposed. Utility Model Content

[0013] By setting the reinforcement plate, the reinforcement plate and the paddle board form a paddle blade as a whole, which further increases the strength of the paddle board. The material of the reinforcement plate can be metal, plastic or other materials. At the same time, the reinforcement plate can be fixed to the paddle board by bonding multiple pieces according to needs. The installation position can also be set at different positions according to the user's different requirements for the force points of the paddle board to meet the strength requirements.

[0014] By setting the reinforcing ribs, the strength of the paddle board 1 and the paddle board 2 is increased, so that the paddle board 1 and the paddle board 2 can be supported by the reinforcing ribs in the horizontal, vertical and oblique directions.

[0015] By setting the mounting holes and the fixing pins, the paddle board 1 and the paddle board 2 are first inserted into the mounting holes through the fixing pins to be pre-fixed, thereby playing the role of connection and positioning.

[0016] By providing rubber coating around the connection between paddle board one and paddle board two, the gap after paddle board one and paddle board two are fixed is sealed, which further prevents water from seeping into the cavity of the paddle board during paddling, increasing the weight of the paddle board and reducing the paddling speed. At the same time, the burrs generated around a circle or locally due to the fixation of paddle board one and paddle board two can also be coated, preventing the user from injuring himself or others when using the paddle board, thereby increasing the safety of use. At the same time, the rubber coating, as an elastomer, has a certain buffering effect when the edge of the paddle board collides with other objects, thereby increasing the service life of the paddle board.
