Abstract

The utility model relates to a composite fibre racket frame, comprising a top frame for the expandable arrangement of a wire side and a handgrip which is extended axially from one side of the top frame, wherein, the top frame is provided with a double-concave slot, whereas the central position of the double-concave slot is provided with a solid slab of spacing type punch holes. In addition, the solid position is provided with a groove which can be used for screen wire to penetrate through to form the wire side. The purposes of the enhancement of the bearing power of the top frame, lightening of the weight, and simple manufacture can also be achieved.

Description

Composite fibre racket frame

The utility model relates to a kind of sports goods, auspicious it, refer to a kind of composite fibre racquet frame.

The integral frame of general composite fibre racket, generally as shown in Figure 1, a top frame (10) wherein, this top frame (10) is to be a shuttle tubulose, because of its material is a composite fibre, make so in the machinery equipment that needs in the manufacture process at HTHP, blow, but the product that its air blowing produces easily causes shuttle tube wall uneven thickness, what easily causes the shuttle tracheal rupture of top frame (10) when being drilled with line hole (11), cause too many defective products, manufacturing cost improves relatively, the Yin Qisuo tube wall is very thin again, when netting twine (12) is subjected to external force application of force square stance, easily causes side walls collapse outside the top frame (10) again, even break so that cause the user can't to one's heart's content bring into play (referring to professional athlete especially) and manufacturing cost too high.

Main purpose of the present utility model is that a kind of composite fibre racquet frame is being provided, and makes composite fibre racquet frame weight reduce to the lightest and does not lose its effect again and exempt to be drilled with the line hole, and defective products is reduced, and then reduces manufacturing cost.

Another purpose of the present utility model is that a kind of composite fibre racket is being provided, and it can strengthen the holding capacity of composite fibre racquet frame and promote the wire side bounce.

According to a kind of composite fibre racquet frame of the utility model, be to include one can open the top frame of establishing and from the handle of this top frame one side shaft for wire side to extension; Be provided with dual-cavity in its top frame, and this dual-cavity central part is the solid plate body of diaphragm formula perforation, and establishes a groove in solid position, can wear for netting twine and form a wire side, more can reach the top frame holding capacity and strengthen and weight saving, make simple and easy purpose.

Now after lifting a preferred embodiment and cooperating graphic explanation what:

Fig. 1 is existing racquet frame and threading schematic diagram;

Fig. 2 is the stereogram of the utility model one preferred embodiment;

Fig. 3 is the composite fibre racquet frame threading schematic diagram of the utility model one preferred embodiment;

Fig. 4 is the A-A cutaway view of the utility model one preferred embodiment;

Fig. 5 is the B-B cutaway view of the utility model one preferred embodiment;

Fig. 6 is the schematic diagram of another preferred embodiment of the utility model.

See also shown in Fig. 2,3, a kind of composite fibre racquet frame of the utility model mainly comprises one and can supply wire side (a 20) top frame (21) of establishing to reach from the handle (22) of one of this top frame (21) side shaft to extension; This top frame (21) is a dual-cavity (211) (seeing Fig. 4 Fig. 5 for details), this dual-cavity (211) central part is the solid plate body of a compartment perforation, a groove (212) is established at the solid position of its what,, netting twine (201) forms a wire side (20) for wearing, when composite fibre racket square stance, wire side (20), stressed situation reaches screen frame (21) dual-cavity (211) by netting twine (201) and locates, and the thickness of dual-cavity (211) relatively is not difficult to find out by Fig. 1 and Fig. 3 just for commonly using the both sides pipe thickness sum of composite fibre shuttle pipe racket frame (10).So composite fibre framework (10) that the big what of top frame (21) holding capacity of the utility model is commonly used, so generally speaking, the composite fibre racket batting power of all commonly using more strengthens, and its this interval perforation of the solid plate body of above-mentioned this compartment perforation is that an ellipticity hole (213) sees also Fig. 4, the both sides at this ellipticity interval (214) and (215) just with dual-cavity (211) on time two ends trim, composite fibre racquet frame material is used minimumly not to be subtracted it again and uses effect and weight to alleviate relatively and more can bring into play its effect of playing ball, especially professional athlete is more paid attention to racket weight, and this ellipticity hole (213) is formed in one with dual-cavity (211), so it is more convenient simple and easy on making; And the solid plate body place of what dual-cavity (211) sees also Fig. 5, is the .I word shape.

Another preferred embodiment composite fibre racquet frame of the utility model, see also shown in Figure 6, the solid plate body place of this dual-cavity (211) embeds a nail (23), and netting twine (201) passes ellipticity hole (213), wears along this nail (23) and forms a wire side (20).

Claims

1, a kind of composite fibre racquet frame, be to include one can open the top frame of establishing and from the handle of this top frame one side shaft for wire side to extension, it is characterized in that: be provided with dual-cavity in its top frame, and this dual-cavity central part is the solid plate body of a compartment perforation, and the solid position of what establishes a groove, can wear for netting twine and form a wire side.

2, a kind of composite fibre racquet frame according to claim 1, the solid plate body place that it is characterized by this dual-cavity embeds the bar nail and accommodates netting twine, forms a wire side.

3, a kind of composite fibre racquet frame according to claim 1, its this interval perforation of solid plate body that it is characterized by compartment is an ellipticity hole.
