Badminton racket with shaft provided with two bends

Abstract

The invention discloses that the racket shaft is made of a material containing carbon fiber, and the racket shaft has two bends: a lower bend and an upper bend, the lower bend is close to the cone cover on the handle, and the upper bend is close to the racket shaft The intersection with the racket frame; several small holes are drilled on the front centerline of the lower bend and the upper bend, making the hardness of these two places softer than other places. The several small holes drilled on the front centerlines of the lower bend and the upper bend are then blocked with other soft materials, and finally the whole racket shaft is processed with a coating to cover up the processing traces of the small holes. The beneficial effect of the invention is that the racket swing speed can be increased, the batting force can be increased, and the production process 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
