Description

A racket frame T-shaped structure

technical field

The utility model relates to a T-shaped structure of a racket frame.

Background technique

Badminton is a kind of ball game suitable for all ages. A common badminton racket is mainly composed of a racket frame, a middle rod and a handle. It forms a net-like racket surface, and the connection between the frame and the middle rod is called a T-shaped structure. For common badminton rackets, as shown in Figure 5, the cross-section of the racket frame is mostly rectangular or oval, and the cross-section of the middle rod is Round shape, the connection between the racket frame and the middle pole is mostly an extension connection of the cross section of the frame and the middle pole. Because it is easy to manufacture and the price is low, it is suitable for beginners. However, the cross-section of the racket frame is designed in a rectangular or oval shape, so the wind resistance when swinging the racket is relatively large, and it is relatively laborious, and the connection structure at the joint is relatively fragile.

Utility model content

The purpose of this utility model is to provide a racket frame T-shaped structure, which can reduce the wind resistance when swinging the racket, and increase the structural strength of the joint between the racket frame and the middle rod.

The utility model is achieved in that the T-shaped structure of the racket frame includes:

A racket frame, whose cross section is hexagonal, viewed from the outside to the inside, includes an outer upright portion, two outer inclined portions connected to one end of the outer upright portion, respectively connected to an outer inclined portion The two inner beveled parts, and the inner upright part connecting one of the two inner beveled parts;

a middle rod, which is circular in cross-section, connected at one end to the frame; and,

A connecting part is located at the connection between the frame and the middle rod. When the frame is placed flat, one end of the connecting part is connected with the frame, the top and bottom two ends of the selfie frame section are along the two sides of the frame. The outer slope faces the left and right sides, and extends obliquely towards the outer upright portion of the racket frame, and is connected to the outer upright portion of the racket frame. The connecting portion is formed with four connecting slopes. The top and bottom ends of the top and bottom form sharp corners, and the cross-section of the connecting portion away from the racket frame is circular, and the cross-sectional area of the connecting portion close to the racket frame is larger than that far away from the racket frame, forming a slightly tapered structure.

According to the utility model, the racket frame, the middle rod and the connecting part are integrally formed; the racket frame, the middle rod and the connecting part are connected by different components; the racket frame is divided into two parts along the extension direction of the middle rod. Sections, the section close to the joint of the middle pole is the lower frame section, the section far away from the middle pole is the upper frame section, and the outer upright part of the racket frame is provided with a concave threading groove at the upper frame section.

The beneficial effect of the utility model is that since the section of the racket frame is hexagonal, and the windward side of the racket is sharp-edged when swinging, it has the effect of cutting wind and can reduce the wind resistance when swinging; The racket frame is also designed with a sharp angle on the windward side, which has the function of assisting in cutting the wind; and the conical connection structure increases the strength of the connection and enhances the torsion of the racket.

Detailed ways

A racket frame T-shaped structure described in the utility model, as shown in Figure 1-4, includes a racket frame 10, a middle rod 20 and a connecting part 30, wherein, the racket frame 10 is an egg-shaped hollow outer shell. The frame, as shown in Figure 4, is a hexagonal cross-sectional shape. Viewed with the racket frame 10 laid flat, the racket frame 10 is sequentially connected to two outer upright portions 11 by an outer upright portion 11 from the outside to the inside. The two outer bevels 12,13 at the end are connected to the two inner bevels 14,15 at one end of each outer bevel 12,13 respectively, and the inner upright portion 16 connecting one end of the two inner bevels 14,15 to form, wherein, The outer parts 12, 13 and the connected inner inclined parts 14, 15 have opposite inclination directions and form pointed corners at the top and bottom ends of the racket frame 10; the outer upright part 11 and the inner upright part 16 are provided with several Corresponding threading holes (not shown in the figure) allow the net wire to pass through and form a net-shaped racket surface in the racket frame 10 .

The middle rod 20 has a circular cross section and is respectively connected with the racket frame 10 and the handle (not shown).

The connecting portion 30 is located at the junction of the racket frame 10 and the middle pole 20, as shown in FIG. The top and bottom ends of the racket frame 10 are extended toward the left and right sides along the two outer slopes 12, 13 of the racket frame 10, and extend obliquely toward the outer upright portion 11 of the racket frame 10, and reach the outer upright portion of the racket frame 10. 11, and form four connection slopes 31, 32, 33, 34, two connection slopes 31, 32 are connected to the outer slope 12, and form a sharp corner at the top of the racket frame 10 section, the other two connection The inclined parts 33, 34 are connected to the outer inclined part 13, and form a sharp angle at the bottom end of the section of the frame 10, and the connecting part 30 is at the proximal rod 20, and the cross-sectional shape is circular, and the connecting part 30 The cross-sectional area at the close-up frame 10 is larger than the cross-sectional area at the mesial rod 20, forming a slightly tapered structure.

As mentioned above, the racket frame has a T-shaped structure, wherein the racket frame 10, the middle shaft 20 and the connecting part 30 are integrally connected in appearance. Out of the frame, or connected by a combination of different components, wrapped into a one-piece appearance.

When the racket frame of the present utility model is in use, because the section of the racket frame 10 is hexagonal, the net wires are passed through the threading holes of the outer upright part 11 and the inner upright part 16 of the racket frame 10, and the outer inclined parts 12, 13 And the inner slope parts 14, 15 form sharp corners at the top and bottom ends of the racket frame 10 section, which has the effect of cutting wind, can reduce the wind resistance when swinging the racket, and can increase the speed of the ball; and the connecting part 30 is also on the racket. The top and bottom ends of the section of the frame 10 are pointed and have the effect of assisting wind cutting, and the conical connection structure can disperse the concentrated stress generated at the connection part 30 when swinging the racket, and the frame of the racket when hitting the ball. and the torsional deformation produced at the middle rod place, increase the connection strength of the racket frame 10 and the middle rod 20 and enhance the torsion of the racket.

The racket frame 10 as described above can be divided into two sections along the extending direction of the middle pole. Preferably, the outer upright portion 11 of the racket frame 10 is provided with a concave threading groove at the upper frame section, so that the net wire can be hidden in the threading groove, reducing the risk of the racket frame 10 contacting the ground when the user swings the racket. When the racket frame 10 collides with other objects, the probability of breaking the net wire is reduced.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form. Anyone with ordinary knowledge in the technical field, if within the scope of the technical features mentioned in the present invention, Equivalent embodiments made with partial changes or modifications using the technical content disclosed in the present model, and without departing from the technical solution content of the present model, all still fall within the scope of the technical features of the present model.
