Abstract
The utility model discloses an improved structure of a badminton racket, which comprises a racket frame and strings. A string groove is arranged on an external ring of the racket frame, strings are threaded on the racket frame through string holes on the string groove, and the cross section of the position at which the string groove contacts with the strings on the racket frame is in circular arc shape. Because the cross section of the string groove of the improved structure of a badminton racket is circular arc shape transition, force on the strings produced when the strings wind the string groove is uniformly distributed on a circular arc section, stress concentration can not be caused, and the strings are not easy to fracture, thereby prolonging the service life of the strings. Besides, force exerted on the surface locating area of the racket frame becomes smaller, strength of the entire racket turns smaller, and the service life of the racket frame is prolonged.
Description
Technical field
The utility model relates to a kind of sports apparatus, particularly relates to a kind of improvement structure of racket.
Background technology
In China's badminton is the sports that the dark broad masses of being subjected to like, it is fit to all kinds of crowds.Racket is one of main apparatus, and the principle of playing badminton is the racket of hitting, make it fast by the tension force of netting twine bounce-back shuttlecock before so that reach the purpose of exercise.The netting twine 2 ' of racket (as shown in Figure 1) is set on the duct of outer rim ring of racquet frame 1 ', commonly use the cross section rectangular substantially (as shown in Figure 2) of the duct 11 ' of shuttlecock, in this kind structure, can produce stress when netting twine 2 ' is walked around duct M-N section on two angles of rectangle concentrates, the discontinuity of netting twine 2 ', rupture easily, influenced the service life of netting twine 2 '.
The utility model content
The purpose of this utility model be to provide a kind of netting twine evenly, the improvement structure of the racket of long service life.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of racket, and it comprises racquet frame and netting twine, is provided with duct on the outer rim ring of racquet frame, and netting twine is set on the racquet frame by the line hole on the duct; The cross section that duct on the described racquet frame contacts with netting twine is circular arc.
After adopting such scheme, because the cross section of the utility model duct is the circular arc transition, the suffered power of netting twine was evenly distributed on the arc section when netting twine was walked around duct, can not produce stress and concentrate, and was not easy fracture, thus the service life of having improved netting twine.And the suffered strength of surperficial location area of frame diminishes the bearing strength minimizing of whole racket, the prolongation in service life of frame.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 2 is a cutaway view of commonly using racket frame duct;
Fig. 3 is a front view of the present utility model;
Fig. 4 is the partial perspective view of the utility model racquet frame;
Fig. 5 is the cutaway view of Fig. 4 along the B-B line.
The specific embodiment
As shown in Figure 3, the utility model is a kind of improvement structure of racket, and it comprises racquet frame 1 and netting twine 2.
Be provided with duct 11 on the outer rim ring of racquet frame 1, netting twine 2 is set in (as shown in Figure 4) on the racquet frame 1 by the line hole 12 on the duct 11; The cross section that duct 11 on the described racquet frame contacts with netting twine 2 is circular arc (as shown in Figure 5).
Emphasis of the present invention just is: the cross section that the duct on the racquet frame contacts with netting twine is circular arc.
