Badminton racket in shape of rounded rectangle

Abstract

The invention discloses a badminton racket in the shape of a rounded rectangle. The badminton racket is composed of a racket frame in the shape of the rounded rectangle, a racket rod and a racket handle. The badminton racket is characterized in that the distance from the center of gravity of the racket frame in the shape of the rounded rectangle to the outer frame rim of a racket head is 111.5mm+ / -5%. For the badminton racket in the shape of the rounded rectangle, the length of the horizontal edge of the racket frame is greater than or equal to the length of the vertical edge of the racket frame; when the length of the horizontal edge of the racket frame is equal to the length of the vertical edge of the racket frame, the racket frame becomes a special case of the racket frame in the shapeof the rounded rectangle: the racket frame in the shape of a rounded square. Compared with well-known badminton rackets, under the condition that the racket frames of the badminton racket in the shape of the rounded rectangle provided by the invention have the same quality and weight, with change of the structure of the racket frame of the badminton racket provided by the invention, the center ofgravity of the racket frame is improved. For the racket frame of the badminton racket provided by the invention, with the obviously improved gravity center, the shuttlecock hitting strength is obviously increased according to the lever principle. A metal cylinder coated with lubricating oil and being capable of sliding freely in a hollow part of the racket rod is placed in the hollow part of theracket rod in advance; a plurality of hollowed parts are processed in the front side of the racket rod, so that the wind resistance to the racket rod during swing of the racket is reduced, and the attack force is improved.

Description

technical field [0001] The invention relates to a badminton racket, in particular to a rounded rectangular badminton racket. Background technique [0002] The racket frame of known badminton racket has two kinds of ellipse and lower oval upper head shape now, and the center of gravity of the racket frame is all 125 mm ± 5% apart from the racket head distance. People with low strength use it to hit the ball with low power and the ball cannot be hit far. For this reason, the solution is that manufacturers continue to improve the material of the racket, although it has improved to some extent, the improvement is not large. In addition, the hollow shaft of the known badminton racket does not have a built-in sliding metal cylinder, which needs to be improved. Also have, the racket shaft of known badminton racket is not hollowed out, and the wind resistance of swinging the racket is big. Contents of the invention [0003] In order to overcome the above disadvantages, the pres...
