Abstract

The utility model discloses a racket frame structure which is characterized in that convex grains are arranged at intervals on line threading positions on the periphery of a racket frame, the convex grains are provided with grooves and line threading holes of the racket frame are arranged between two convex grains. Because the convex grains are arranged among the line threading holes on the periphery of the racket frame of the utility model and simultaneously the convex grains are provided with the grooves, when lines are threaded on a racket, after net lines are penetrated from a line threading nail of a line threading hole, are stridden over the convex grains, and are arranged in the grooves, the lines are penetrated from a line threading nail of a next line threading hole. Net lines of the racket formed by the method are tightly attached to the convex grains of the racket frame. Therefore, the convex grains fill gaps among the two line threading holes and the racket frame and simultaneously the convex grains also enlarge the area of the cross section of the racket frame. Consequently, the rigidity of the racket frame can be reinforced and the service life of the racket frame can be enhanced.

Description

The frame of racket structure

Technical field

The utility model is the racket about a kind of tennis and shuttlecock, is meant the frame of racket structure especially.

Background technology

Tennis and badminton are the popular motions of comparatively popularizing, and the structure of racket is also in continuous innovation.Because in the process of playing ball, frame can touch ground, so for preventing that netting twine from being rubbed, as shown in Figure 1, currently used frame structure, it is periphery formation groove 2 ' at frame 1 ', and through wires hole 21 ' is provided in a side of in this groove 2 ', and the netting twine of then putting on 3 ' is to place this groove 3 ', when racket contacts with ground, can not be ground to netting twine 3 ', and the service life of the netting twine 3 ' that extended.But but there are the following problems for the frame of racket structure of this structure:

1, (cooperate Fig. 2, shown in 3), be netting twine 3 ' when the through wires hole 21 ' that is placed through frame 1 ', for preventing through wires hole 21 ' incised wound netting twine 3 ', when threading, on each through wires hole 21 ', be combined with threading nail 4 ', netting twine 3 ' is fixed on the frame by this threading nail 4 ', because the setting of threading nail 4 ', make netting twine 3 ' when passing two through wires holes 21 ', netting twine 3 ' has a gap with the bottom of frame 1 ' groove 3 ', therefore after racket used a period of time, netting twine 3 ' the stressed threading of can oppressing followed closely 4 ', and threading nail 4 ' can move down, the netting twine 3 ' and the gap of frame 1 ' groove 3 ' are dwindled, netting twine 3 ' can fluff relatively, makes netting twine 3 ' move back pound, the balling effect when influence is used.

2, because the periphery of frame forms flutedly, then reduced the cross-sectional area of frame, thereby the rigidity of frame can reduce, influence the service life of frame.

The utility model content

The purpose of this utility model is to provide a kind of frame of racket structure, and it can make netting twine not have the gap with contacting of frame periphery, with the cross-sectional area increasing of seasonal frame, to improve the rigidity of racket.

For achieving the above object, technical solution of the present utility model is: the frame of racket structure, be at the periphery threading place of frame of racket at interval be provided with protruding grain, protruding grain is provided with groove, and the through wires hole of frame is provided in a side of between the two protruding grains.

After adopting such scheme, owing between through wires hole, be provided with protruding grain on the periphery of the frame of the utility model racket, simultaneously protruding grain is provided with groove, therefore racket is when threading, netting twine is to stride across protruding grain and place the groove back to pass from the threading nail of next through wires hole after the threading of through wires hole nail passes, the racket that forms like this, its netting twine is to be close on the protruding grain of frame, therefore this protruding grain has not only been filled up between two through wires holes gap with frame, this protruding grain has also strengthened the area of frame section simultaneously, thereby can strengthen the rigidity of frame, improve the service life of frame.

The specific embodiment

As shown in Figure 4, frame structure of the present utility model, be at the periphery threading place of frame 1 at interval be provided with protruding grain 2, on protruding grain 2, be provided with groove 21, on the frame 1 between the two adjacent two protruding grains 2, be provided with through wires hole 11, be equipped with threading nail 4 in each through wires hole 11.

Cooperate Fig. 5; 6; shown in 7; when on this frame 1, placing netting twine 3; because the height of each protruding grain 2 is to be higher than the height that threading nail 4 protrudes out outside the through wires hole 11; therefore when netting twine 3 enters next through wires hole 11 after the threading nail 4 of through wires hole 11 passes; netting twine 3 is to be close in the groove 21 of protruding grain 2; 21 pairs of netting twines 3 of this groove have a defencive function; prevent from behind frame 1 kiss the earth netting twine 3 to be rubbed; because placing the back, netting twine 3 do not have the gap with the periphery of frame 1; so it in use for some time; the problem of " moving back pound " as the product as commonly using can not appear in netting twine 3, to have guaranteed the dynamics of batting.Simultaneously, because 2 settings in frame 1 periphery of protruding grain can make the area of the section of frame 1 strengthen, thereby can improve the rigidity of frame 1.

Claims

1, a kind of frame of racket structure is characterized in that: be at the periphery threading place of frame of racket at interval be provided with protruding grain, protruding grain is provided with groove, and the through wires hole of frame is provided in a side of between the two protruding grains.
