Badminton racket with shaft provided with two bends

Abstract

The invention discloses a shaft which is made from a material containing carbon-containing fiber. The shaft is provided with two bends, namely, the lower bend and the upper bend, the lower bend is close to a taper cover on a handle of a racket, and the upper bend is close to the cross point of the shaft and a frame of the racket; multiple small holes are drilled in front center lines of the lower bend and the upper bend, so that the lower bend and the upper bend are softer than other places, the multiple small holes drilled in the front center lines of the lower bend and the upper bend are blocked with other soft materials, finally, a coating is machined on the whole shaft, and the machining marks of the small holes are concealed. The shaft has the advantages that the swing speed can be increased, the striking force is increased, and the production technology is simple.

Description

technical field [0001] The invention relates to a badminton racket, in particular to a badminton racket with two curved parts in the shaft. Background technique [0002] The diameter of the racket shaft of known badminton rackets is all the same from the bottom to the top, or the diameter from the bottom to the top gradually becomes thicker, and there are no two twists and turns in the middle. And in the actual playing process, when just starting to swing the racket, due to the effect of inertia, a lot of strength is needed to start, which causes the initial speed of the swing to reduce, and finally the batting power is not large enough. Application number 2017104178469, the badminton racket invented by Wu Huilin with two narrow tubes in the shaft, can overcome the above shortcomings, but the force strength of the two thin tubes of the shaft becomes lower due to the smaller diameter, leaving hidden dangers . Application number 201710489719X, Wu Huilin invented a badminton ...

AI Technical Summary

Problems solved by technology

However, in the actual playing process, at the beginning of the swing, due to the effect of inertia, it takes a lot of effort to start, resulting in a decrease in the initial speed of the swing, and finally the hitting force is not strong enough.

Application number 2017104178469, the badminton racket invented by Wu Huilin with two narrow tubes in the shaft, can overcome the above shortcomings, but the force strength of the two thin tubes of the shaft becomes lower due to the smaller diameter, leaving hidden dangers

Application number 201710489719X, Wu Huilin invented a badminton racket with two curved shafts, which can overcome the above-mentioned shortcomings, but the shaft needs to be manufactured with a combination of two different materials containing carbon fibers, the production process is complicated and the cost is high
