Description

Badminton racket

Technical Field

The utility model belongs to the technical field of sports equipment and specifically relates to a badminton racket is related to.

Background

A badminton racket generally comprises a handle, a shaft (i.e., a middle tube), and a joint (T-head) between a frame and the shaft. The length of a racket is not more than 68 cm, wherein the lengths of a racket handle and a racket rod are not more than 42 cm, the length of a racket frame is not more than 25 cm, and the width of the racket frame is 20 cm. The performance of a badminton racket depends to a large extent on the middle tube.

At present, the middle tube is mostly made of carbon fiber into a round tube shape, the rigidity consistency is poor, and the recovery after the swing is slow.

Disclosure of Invention

In view of the above, there is a need to provide a badminton racket with small wind resistance coefficient and high strength.

In order to solve the technical problem, the technical scheme of the utility model is that: a badminton racket comprises a racket handle, a middle tube made of carbon fiber and a racket frame with a T-shaped head, wherein the middle tube comprises an upper part with a round cross section, a middle part with a square cross section and a lower part with a round cross section, the plane where two opposite edges and corners in the middle of the middle tube are located is perpendicular to the plane where the racket frame is located, and a continuous bending reinforcing rib is arranged on the outer side wall of the middle part of the middle tube.

Furthermore, the middle outer side wall and the upper outer side wall of the middle pipe are in smooth transition, and the middle outer side wall and the lower outer side wall are in smooth transition.

Furthermore, the cross section of the middle pipe is rhombic.

Furthermore, the cross section of the middle part of the middle pipe is square.

Furthermore, the included angle between the reinforcing rib and the edge in the middle of the middle pipe is 45 degrees.

Furthermore, the lower part of the middle pipe is positioned in the racket handle, and the upper part of the middle pipe is connected with the T-shaped head.

Furthermore, the radius of the corner fillet in the middle of the middle pipe is 0.5-1 mm.

Furthermore, the height of the reinforcing rib is 0.1-0.2 mm.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. novel molding well pipe (the cross section is the square), the closed angle towards racket hitting direction, reduces the windage coefficient, promotes the impact force, sweeps power to and racket torsion, the intensity of pipe in the reinforcing, the side direction antitorque degree when increasing the batting not clapping the central point makes the drop point control more accurate, cooperation knife face frame type and compression groove section reduce the windage and promote batting speed, reinforcing frame intensity.

2. The T head and the upper part of the square middle tube are smoothly excessive by adopting a circular tube, so that the integral stability of the racket is ensured without damaging the structure of the T head.

3. In the middle pipe with the same outer diameter and material, the torsion of the middle pipe can be increased by 5-6 degrees compared with that of the square middle pipe, and one level is increased.

4. The rigidity consistency of the middle tube is increased, the elasticity and the racket torsional angle are improved, and the middle tube can be recovered more quickly.

In order to make the aforementioned and other objects, features and advantages of the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Fig. 3 is a schematic structural view of a cross section of the middle tube in the embodiment of the present invention.

In the figure: 1-racket handle, 2-middle tube, 21-lower part, 22-middle part, 23-upper part, 24-reinforcing rib, 3-racket frame and 31-T head.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-3, a badminton racket comprises a racket handle 1, a middle tube 2 made of carbon fiber and a racket frame 3 made of carbon fiber and provided with a T-shaped head 31, wherein the middle tube 2 comprises an upper part 23 with a circular cross section, a middle part 22 with a square cross section and a lower part 21 with a circular cross section, the planes of two opposite edges of the middle tube middle part 22 are vertical to the plane of the racket frame, and the outer side wall of the middle tube middle part 22 is provided with a continuous W-shaped bent reinforcing rib 24.

In this embodiment, the outer side wall of the middle pipe middle portion 22 and the outer side wall of the upper portion are in smooth transition, and the outer side wall of the middle pipe middle portion 22 and the outer side wall of the lower portion 21 are in smooth transition. The overall stability of the racket is ensured without damaging the structure of the T head.

In this embodiment, the angle between the edge of the middle tube middle part 22 and the reinforcing rib 24 is 45 degrees.

In this embodiment, the lower part 21 of the middle tube is located in the racket handle, and the upper part 23 of the middle tube is connected with the T-shaped head 31.

In this embodiment, the corner fillet radius of the middle tube middle portion 22 is 0.5-1 mm.

In this embodiment, the height of the reinforcing rib 24 is 0.1-0.2 mm.

This racket effectively reduces the windage coefficient through novel molding square well pipe, promotes the impact force, sweeps power to and racket torsion, the intensity of reinforcing well pipe increases the batting and is not the side direction antitorque degree when clapping the central point, makes the drop point control more accurate, cooperation knife face frame type and compression groove section reduce windage promotion batting speed, reinforcing frame intensity.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
