Description

Carbon fiber badminton racket

Technical Field

The utility model relates to a racket especially relates to a carbon fiber racket.

Background

In order to pull 35 pound high-weight threads, the racket frame of the existing carbon fiber badminton racket is generally reinforced by a plurality of carbon yarn sheets, so that the weight of the whole racket is heavier, and the swinging speed is influenced when the racket frame is heavier; or the size of the racket frame is increased, so that the wind resistance of the racket swinging is also greatly increased.

Application number 201810402246X is based on racket of golden ratio, characterized by: the middle pipe is made of two materials with different hardness characteristics according to the golden ratio of 0.618, and specifically comprises the following steps: the section from the front head of the wood handle to the junction of the racket frame and the middle pipe is made of relatively hard materials, and the section from the front head of the wood handle to the golden section point of 0.618 is made of relatively soft materials. The application has 2 disadvantages, one is that the golden ratio of 0.618 is designed based on the middle tube, not based on the length of the whole racket, so the golden section point is not the optimal position; the other disadvantage is that the middle tube needs to be made of two materials with different hardness, the manufacturing process is complex, and the cost is high.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a carbon fiber badminton racket.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is:

the utility model provides a carbon fiber racket, comprises carbon fiber frame, carbon fiber well pipe and handle, characterized by:

the racket frame is expanded by 2-3 mm in thickness towards the center direction of the racket frame at the positions of 2 o 'clock and 10 o' clock, and the length of the expanded position is 2-3 cm; the golden section point of the golden ratio of 0.618 of the racket is based on the length of the whole racket, particularly the golden section point is at the position of 0.618 (the length of the racket), the golden section point smoothly transits towards the two ends of the middle pipe, the diameter of the middle pipe in the smooth transition range is reduced by 8% -10% compared with the diameter of the middle pipe at other positions, and the length of the middle pipe is 2-4 cm.

Furthermore, tungsten beads with the diameter of 0.3-1 mm and the weight of 0.5-2 g are arranged in the hollow middle tube, so that the killing force can be increased suddenly.

A large number of practices prove that the weakest place of the carbon fiber racket frame stay wire is the area at the 2 o 'clock and 10 o' clock directions, the utility model only increases the size in the area, so that the strength of the area is greatly improved, but the whole racket frame is not obviously increased in weight; meanwhile, the weak racket frame areas at 1 o 'clock and 3 o' clock on two sides of the 2 o 'clock are reinforced, and the weak racket frame areas at 9 o' clock and 11 o 'clock on two sides of the 10 o' clock are reinforced.

The golden section point of the golden ratio 0.618 of the utility model is based on the length of the whole racket, not on the length of the whole middle tube; the utility model discloses a well pipe adopts the gold section point performance that the technique of reducing well pipe diameter realized, the utility model discloses preparation simple process, it is with low costs. The utility model discloses the windage of the thin center tube reduction of golden section point department can offset the windage that the frame expansion department increases basically.

The utility model has the advantages that the utility model can draw a 35 pound high line without obviously increasing the weight of the whole racket frame; meanwhile, the middle pipe only adopts one material to realize the golden section point performance of the whole racket with the golden ratio of 0.618, the utility model has simple manufacturing process and low cost. The utility model discloses the windage of the thin center tube reduction of golden section point department can offset the windage that the frame expansion department increases basically. The utility model discloses built-in tungsten pearl in well pipe cavity can increase the killing power suddenly.

Drawings

The invention will be further described with reference to the accompanying drawings and examples. Fig. 1 is a schematic diagram of the present invention.

1 is the frame, 2 is the middle tube, 3 is the handle, 4 is the golden section point, 5 is the expansion, a is the racket length, b =0.618 a, c is the length of the thin middle tube.

Detailed Description

In 1, a carbon fiber racket comprises carbon fiber frame 1, carbon fiber well pipe 2 and handle 3, characterized by:

the racket frame 1 is expanded by 2 mm in thickness towards the center direction of the racket frame 1 at the positions of 2 o 'clock and 10 o' clock, and the length of the expansion part 5 is 2 cm; golden section point 4 of golden ratio 0.618 of the racket is based on the length a of the whole racket, specifically, the golden section point 4 is at the place where b =0.618 a, the golden section point 4 smoothly transits to the two ends of the middle tube 2, the diameter of the middle tube in the smooth transition range is reduced by 10% compared with the diameter of the middle tube at other places, and the length c of the middle tube is 3 cm. The tungsten beads with the diameter of 0.5 mm and the weight of 1 g are arranged in the hollow middle tube, so that the killing force can be increased suddenly.

A large number of practices prove that the weakest place of the stay wire of the carbon fiber racket frame 1 is the area of the racket frame 1 in the 2 o 'clock and 10 o' clock directions, the utility model only increases the size in the area, so that the strength of the area is greatly improved, but the whole racket frame 1 is not obviously increased in weight; meanwhile, the 2 o 'clock two-side weak regions at 1 o' clock and 3 o 'clock are reinforced, and the 10 o' clock two-side weak regions at 9 o 'clock and 11 o' clock are reinforced.

One example of the utility model is that the finished racket made of carbon fiber can pull 35 pound high pound thread, which only weighs 78 g and is a very light racket of 5U.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments do not depart from the technical spirit of the present invention, and still fall within the scope of the technical solution of the present invention.
