Abstract

The utility model discloses an improved structure of an aluminium alloy racket frame, which comprises an aluminium alloy head frame, a triangular part and a handle segment, wherein the triangular part is divided into a left and a right yoke parts and a moon eyebrow. The aluminium alloy head frame is at least connected with a segment of carbon fiber pipe of composite material and namely two segments of carbon fiber pipes of the composite material are symmetrically connected to positions from a point of 2 to a point of 4 and form a point of 8 to a point of 10. In this way, carbon fiber composite material relative to aluminum alloy material has excellent strength, rigidity and damping characteristic. The carbon fiber pipes of the composite material are added in the aluminium alloy head frame to make the carbon fiber pipes of the composite material bear higher tension of net lines. A sweet zone of hitting a ball is enlarged. The structural strength, the shock avoiding character, the hitting feeling and the weight of the utility model are similar to a carbon fiber racket. But the improved structure of an aluminium alloy racket frame has low cost. Correspondingly, the utility model has higher cost benefit. The improved structure of an aluminium alloy racket frame is suitable for a tennis racket, a wall ball racket, etc.

The specific embodiment

Seeing also shown in Figure 2ly, is the structure improved embodiment one of racket frame of the present utility model, comprises a frame 1, triangle portion 2 and handle section 3.

Frame 1 similar ellipse, a frame 1 down is a triangle portion 2, the cross section of a frame 1 such as Fig. 2 A.

Triangle portion 2 similar dels, the triangular apex position is a throat, the segmental arc on triangle both sides is a left and right yoke portion 21, and triangle base segmental arc is a month eyebrow 22.

Throat is following to be handle section 3 for hand holding part part, and the cross section of triangle portion 2 and handle section 3 and this case are irrelevant, do not do diagram at this.

Key of the present utility model is: a frame 1 (cross section such as Fig. 2 A) forms for the aluminium-alloy pipe bending, at least inserting one section carbon fibre reinforced pipe 4 on aluminium alloy head frame 1, is 2 o'clock to 4 o'clock and two sections carbon fibre reinforced pipes 4 of position symmetry access in 8 o'clock to 10 o'clock at aluminium alloy head frame 1 shown in Fig. 2 and Fig. 2 B.

The specific embodiment cooperates shown in Fig. 2 and Fig. 2 B, aluminium alloy head frame 1 was at 2 o'clock to 4 o'clock and two sections carbon fibre reinforced pipes 4 of position symmetry access in 8 o'clock to 10 o'clock, promptly, aluminium alloy head frame 1 is at 2 points, 4 and 8 points, 10 positions respectively have a free end 11, two sections in type carbon fibre reinforced pipes 4 respectively have two free ends 41, wherein two of one section carbon fibre reinforced pipe 4 free ends 41 are socketed in respectively on 2 of aluminium alloy head frame 1 and 4 free ends 11,41 of two free ends of another section carbon fibre reinforced pipe 4 are socketed in respectively on 8 of aluminium alloy head frame 1 and 10 free ends 11, the free end 11 of each socket place and the faying face of free end 41 are with adhesive means or 12 combinations of other joint material, make two sections carbon fibre reinforced pipes 4 insert and 8 o'clock to 10 o'clock positions of aluminium alloy head frame 1 at 2 o'clock to 4 o'clock, and constitute aluminium alloy head frame 1 with two sections carbon fibre reinforced pipes 4.

The free end 11 of aluminium alloy head frame 1 can be inner cased type with the socket mode of the free end 41 of carbon fibre reinforced pipe 4, shown in Fig. 3,3A, the free end 41 of carbon fibre reinforced pipe 4 is enclosed within on the free end 11 of aluminium alloy head frame 1, also can be jacket-type, shown in Fig. 4,4A, the free end 11 of aluminium alloy head frame 1 is enclosed within on the free end 41 of carbon fibre reinforced pipe 4.
