In the above technical solution of the present invention, the inner wall of the head frame has a through hole corresponding to the shaft hole of the shaft.

It also includes a shock absorber plugged in the shaft hole of the shaft and adjacent to the head frame.

The bottom plate has a through hole corresponding to the position of the shaft.

The bottom plate has a transparent area corresponding to the position of the shaft.

By adopting the above-mentioned technical solution, the badminton racket provided by the utility model has high structural strength, the shaft rod is not easily twisted and deformed, and the ball control ability is excellent.

Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings.

As shown in FIGS. 1-4 , the badminton racket 10 provided by the first preferred embodiment of the present invention includes a head frame 20 , a shaft 30 , a handle 40 , a collar 50 and a bottom plate 55 . The head frame 20 , the shaft 30 and the handle 40 are made of carbon fiber reinforced resin, the carbon fiber can be replaced by glass fiber, boron fiber or Kevlar fiber, and the resin can be thermosetting resin or thermoplastic resin.

The head frame 20 has an outer wall 21 , an inner wall 22 , a chamber 23 inside the head frame 20 and a plurality of threading holes 24 passing through the outer wall 21 and the inner wall 22 . The head frame 20 is located on a virtual plane P.

As shown in FIG. 2 , the shaft 30 integrally extends from the outer wall 21 of the head frame 20 , and the shaft 30 has a shaft hole 32 communicating with the chamber 23 of the head frame 20 .

As shown in Figures 3 and 4, the handle 40 has an outer tube 41, an inner tube 44 for the shaft 30 to extend into, and two ribs 45 integrally connecting the outer tube 41 and the inner tube 44, and the outer tube 41 The interior is divided into two empty chambers 46, the outer tube 41 has a tapered head 42, and a straight rod-shaped body 43 extends from the head 42, and the inner tube 44 is located inside the outer tube 41 and uses its The top end is connected with the head 42 of the outer tube 41 , and the bottom end thereof is substantially flush with the end of the outer tube 41 , and the two ribs 45 are located on the imaginary plane P (as shown in FIG. 4 ).

The collar 50 is disposed at the end of the handle 40 , and the bottom plate 55 is disposed between the handle 40 and the collar 50 and is attached to the outer tube 41 and the inner tube 44 . The bottom plate 55 has a hole 56 corresponding to the position of the shaft 30 , the user can see the shaft 30 through the through hole 56 .

Because the shaft rod 30 is extended from the head frame 20 to the end of the handle 40, its length reaches the limit, and the shaft rod 30 is formed before being integrally connected with the head frame 20 and the handle 40 during manufacture. Furthermore, the handle 40 With the inner tube 44 and the ribs 45, the strength of the overall structure is improved compared with the existing structure, and the shaft 30 is not easily twisted and deformed during use, and the ball control ability of the badminton racket can be improved.

According to the creative spirit of the present utility model, the structure of the badminton racket can be changed and designed, as shown in Fig. 5 and Fig. 6, the badminton racket 60 provided by the second preferred embodiment of the present utility model is different from the previous embodiment. It is that: the inner wall 64 of the head frame 62 has a through hole 66 corresponding to the shaft hole 70 of the shaft 68, so that the end of the shaft 68 close to the head frame 62 is open (as shown in FIG. 5 ). The two ribs 74 of the handle 72 are perpendicular to the imaginary plane P, so that the handle 72 can withstand a relatively large stress in this direction (as shown in FIG. 6 ). In addition, the badminton racket 60 also has a shock-absorbing member 80 plugged in the shaft hole 70 of the shaft 68 and adjacent to the head frame 62 to absorb the shock generated when hitting the ball (as shown in FIG. 5 ). In fact, the number and arrangement direction of the ribs can be changed. As shown in FIG. 7, the bottom plate 76 has a transparent area 78 instead of the perforation and corresponds to the position of the shaft 68, so that the shaft 68 can be seen from the outside, if not Installing the shock-absorbing member 80 , the user can even see through the shaft hole 70 of the shaft 68 and prevent foreign objects from entering the shaft hole 70 of the shaft 68 through the bottom plate 76 .

The above are only two preferred embodiments of the utility model, and all structural changes that can be obtained without paying creative work according to the utility model description, claims and accompanying drawings should be covered by the utility model. covered by patent protection.
