Abstract

The utility model relates to the manufacture field of sporting goods and provides a carbon fiber badminton racket. The carbon fiber badminton racket is composed of a racket frame, a racket rod and a racket handle, wherein the racket frame, the racket rod and the racket handle are connected sequentially, strings are wound on the racket frame tightly, the shapes of sections of the racket frame and the racket rod are polygonal hollow tubes, and the polygon is a rectangle or a pentagon or a hexagon or a heptagon or an octagon. The shape of the section of the racket frame is a diamond hollow tube, so that the rigidity of the racket frame and the racket rod is improved, and transformation and damage during a using process are prevented. Manufacturing materials of the racket frame and the racket rod are carbon fiber composite materials, so that the strength of the badminton racket is improved by more than 5 times, and breakage during using is prevented. The racket frame and the racket rod are of an integrated structure, and breaking off or separating possibly occurring between the racket frame and the racket rod is prevented. In addition, the racket rod which is of a hexagonal hollow structure enables connection between the racket rod and the racket handle to be good, and prevents breaking away caused by rotation between the racket rod and the racket handle.

Description

A kind of carbon badminton racket

Technical field

The utility model relates to the sports articles for use and makes the field, specifically is meant a kind of racket.

Background technology

Carbon fiber is through carbonization and graphitization processing and the micro crystal graphite material that obtains by organic fiber.The similar Delanium of the microstructure of carbon fiber is a random graphits structure.

The main application of carbon fiber is compound with matrixes such as resin, metal, potteries, processes structural material.Carbon-fibre reinforced epoxy resin composite material, its specific strength, specific modulus overall target are the highest in the existing structure material.In density, rigidity, weight, fatigue properties etc. the field of strict demand is arranged, requiring high temperature, occasion that chemical stability is high, carbon fibre composite all has much advantage.

The advantage of carbon fibre composite:

1, high strength (be iron and steel 5 times);

2, outstanding hear resistance (can tolerate the high temperature more than 2000 ℃);

3, outstanding thermal-shock resistance;

4, low thermal coefficient of expansion (deflection is little);

5, thermal capacity little (energy-conservation);

6, proportion little (steel 1/5);

7, outstanding anticorrosive and radiance.

Excellent properties based on multiple emerging composite (like polymer composite, metal-base composites, ceramic matric composite) such as carbon fibre composite; People expect, the human epoch that on material is used, just entering into a composite extensive use from the iron and steel epoch.

China has obtained rapid progress in recent years economically, and people pay attention to spiritual civilization more when pursuing material progress, and theories such as low-carbon (LC), green, health are constantly advocated.Everybody especially is concerned about teen-age fitness and healthy problem, because this is related to the future of country.Improve teen-age fitness, the best way is to participate in physical training, participates in badminton.

Badminton is a kind of body-building; Wanting ground on the scene ceaselessly to carry out step during match moves, jumps, turns, swings the bat; Thereby increased the strength of upper limbs, lower limb and waist muscle, accelerated person taking exercise's systemic blood circulation, strengthened the unify function of respiratory system of cardiovascular system.Carry out shuttlecock for a long time and take exercise, can make heartbeat powerful, lung capacity strengthens, and endurance improves.In addition, badminton requires the practitioner in the short time fast changing course of action to be made judgement, hits back decidedly, and therefore, it can improve the sensitivity and the harmony of nerve system of human body.

Participating in badminton only needs two rackets, a ball and a rope to get final product.The racket of prior art adopts aluminium alloy or plastics manufacturing, and the strength of materials is not enough; Fracture easily, and the cross section of frame and dabber is circular or oval that dabber is connected insecure with handle; Dabber and handle easy separation injure own or other people at the volley.

Summary of the invention

The problems referred to above for the racket that solves prior art exists the utility model provides a kind of racket.

The technical scheme that the utility model uses is following:

A kind of carbon badminton racket is made up of the frame that is linked in sequence, dabber and handle, tightens around the string of a musical instrument at frame, and the cross sectional shape of said frame and dabber is the polygon hollow tube, and the manufactured materials of frame and dabber is a carbon fibre composite.

Said polygon is a kind of in rectangle, pentagon, hexagon, heptagon and the octagon, preferred hexagon.

The cross sectional shape of said frame is the rhombus hollow tube.

Said frame and dabber are integral structure.

The beneficial effect of the utility model is:

1) use carbon fibre composite that the intensity of racket is improved more than 5 times, fracture when preventing to use injures own or other people.

2) cross sectional shape of frame and dabber is the polygon hollow tube, improves the rigidity of frame and dabber, prevents the damage that deforms in the use.

3) frame and dabber are integral structure, stop contingently between frame and the dabber to fracture or separate.

4) dabber is the hexagon hollow tubular structure, makes it better with being connected of handle, prevents dabber and handle owing to rotate each other, and causes disengaging.

The specific embodiment

Fig. 1 is a kind of carbon badminton racket sketch map of the utility model, is made up of the frame that is linked in sequence, dabber and handle, tightens around the string of a musical instrument at frame, and the cross sectional shape of said dabber is the hexagon hollow tube, sees Fig. 3; The cross sectional shape of frame is the rhombus hollow tube, sees Fig. 2; The manufactured materials of frame and dabber is a carbon fibre composite; Frame and dabber are integral structure, and dabber firmly connects handle.

A kind of carbon badminton racket manufacturing process is following:

1) makes or buy carbon cloth, make the mould of frame and dabber integral structure;

2) at the mould inner surface application of lubricating, a coating adhesive of carbon cloth is attached to mould inside, after pasting the multilayer carbon cloth, mould is filled up, and pastes plastic sheeting again on the surface;

3) air of mould inside is released, pours into epoxy resin subsequently, treat hardening of resin after, promptly accomplish the making of frame and dabber;

4) processing and fabricating string holes;

5) with wooden or metal, plastic handle, connect dabber and frame, tightly around the string of a musical instrument, a kind of carbon badminton racket of promptly accomplishing is made in the string holes of frame.

Claims (4)

1. carbon badminton racket; Form by the frame that is linked in sequence, dabber and handle; Tighten around the string of a musical instrument at frame, it is characterized in that: the cross sectional shape of said frame and dabber is the polygon hollow tube, and the manufactured materials of frame and dabber is a carbon fibre composite.

2. a kind of carbon badminton racket according to claim 1 is characterized in that: said polygon is a kind of in rectangle, pentagon, hexagon, heptagon and the octagon.
