Problems solved by technology

Often when we use aluminum alloy to make oars, we will use one-piece molding. This method will make it very convenient to store the oars, and often makes it inconvenient to store the oars when they are not in use, occupying an area larger area
At the same time, some combined paddles will adopt the setting of the inner space to reduce the weight of the paddle. This method will easily allow water to enter from the joint. After the water enters, it will easily increase the weight of the paddle and make the paddle fall easily. Shen, these are the problems we need to solve

Abstract

The invention discloses an aluminum alloy paddle, comprising a paddle rod, a handle and a paddle plate; one end of the paddle rod is provided with an outside thread of the paddle rod, and the other end of the paddle rod is provided with an inside thread of the paddle rod; one end of the handle is provided with an outside thread of the handle, the handle is in threaded connection with the inside thread of the paddle rod through the outside thread of the handle; the front face of the paddle plate is provided with a diagonal guide flow groove and a long guide flow groove; the top part of the paddle plate is provided with an installing convex rod, and an installing hole is arranged in the installing convex rod; an inside thread of the installing hole is arranged on the inner wall of the installing hole; one end of the paddle rod containing the outside thread of the paddle rod is in threaded connection with the inside thread of the installing hole. The paddle can be made by a combining method; thus the paddle can be conveniently folded in idle state; meanwhile, the paddle body is a hollow structure, and foam is plugged in the hollow structure so as to prevent water entering the paddle body; meanwhile, the floating force of the paddle can be largely increased, thus the paddle can be floated at the water surface, and paddle can be prevented from falling in the water and sinking to the bottom part.

Description

Technical field [0001] The invention relates to the technical field of ship oars, in particular to an aluminum alloy ship oar and a manufacturing process thereof. Background technique [0002] The oar is a rowing tool. The upper end is a round rod, which is good for hand grip, called a grip rod; the lower end is a plate-shaped, called a paddle board, used to pump water, using Newton's third law of physics, through the reaction force of water waves, to make the ship move forward. Aluminum alloy material can be widely used in the production of boat oars due to its higher strength and lighter performance. Often when we use aluminum alloy to make the oars, we will adopt the integrated molding method. This method will make the oars very convenient to be stowed, and often make it inconvenient to fold the oars when not in use, and occupy land. Large area. At the same time, in some combined oars, the hollow setting is adopted to reduce the weight of the oars. This method will easily a...
