Abstract

The invention belongs to a component of a boat or a ship, and particularly relates to a paddle for a boat or a ship. The paddle is characterized in that the included angle of a paddle rod and a paddle back is 3-20 degrees; the contacting surface of a handle of the top part of the paddle rod and the palm surface is processed into an arc-shaped surface coincided with the palm surface; a paddle neck of the paddle rod is processed into an oval cross section; and the contact surface of the handle and fingers or the smooth surface is provided with a finger groove. The paddle has the advantages that: 1. when a paddle blade is in water, the upper part of the paddle blade can set a supporting point fast in water; 2. when in paddling, the angle of the paddle and the force of the arm are effectively combined in the process of paddling period, and an optimum force-applying angle can be formed; when being out of water, since the angle of the paddle is beneficial to lift the paddle, the forward resistance of the boat can be reduced; 3. the paddle neck is made into an oval shape, and on the basis of increasing the strength of the paddle rod, the paddle-pushing gesture is changed, thus being beneficial to the transmission linkage by which the muscle applies force on the paddle of the boat; and 4. the change of the handle of the paddle leads the hand feeling to be more comfortable and is more consistent with the physiological characteristics of the hand.

Description

technical field [0001] The invention belongs to parts of boats and boats, in particular to a paddle used for boats and boats. Background technique [0002] At present, the rowing used by boats and boats, whether it is dragon boats or racing boats, kayaks, leisure boats, etc., is to push the hull forward by rowing, which is based on physical fitness. In order to increase the speed of the boat, people have done more research on human physiology and biochemistry, but less research on the shape and performance of paddles from the perspective of sports biomechanics combined with fluid mechanics; Traditional and customary rowing, its structure includes the paddle shaft, the paddle surface, the back of the paddle and the handle on the top of the paddle shaft. At the bottom of the neck of the cone-shaped paddle shaft with a small top diameter and a large bottom diameter, there is a paddle surface, The back of an oar is joined together as a single blade. It has following shortcomin...
