Problems solved by technology

[0014] The shuttlecock made of artificial feathers that has appeared in recent years has the problem that most of the feather stem materials that can be used for artificial feathers are far inferior to the feather stems of goose and duck feathers in terms of specific strength (the ratio of mechanical strength to sample weight) , especially in terms of rigidity, it is not easy to reach the strength of goose and duck feathers, and the stiffness (rigidity) of artificial pinna materials is not as good as that of goose and duck feathers
Second, in order to reduce the weight of the rotating component to the greatest extent and at the same time increase its rotating wind resistance, the structure of the rotating component will be relatively complicated, and the corresponding injection mold will become very complicated
If the ball skirt struts are made together, it will pose a huge challenge to mold design and processing, and the cost will be very high; and some more complex conjoined structures cannot be successfully injected at all.
After separate and independent molding, the above difficulties are solved

Embodiment 1

[0067] like figure 1 Shown, shuttlecock comprises ball head 11, ball skirt 12, ball skirt strut 13, reinforcing ring 14 and rotating component 15, and ball skirt 12 and ball skirt strut 13 are made of 15 or 16 artificial feathers; Rotating component 15 is a A long sheet of material.

[0068] like figure 2 As shown, nylon is selected as the material for making the rotating member 15, and the production process of plastic injection molding is used to produce a sheet-shaped rotating member 15 with small holes at both ends. During installation, the ball skirt strut 13 is passed through the small hole of the pull ring of the rotating member 15, and then inserted into the ball head 11 for fixing. It should be noted that each ball skirt strut 13 passes through the small holes of the pull rings of the two rotating components 15 , which are the high hole and the low hole of the two rotating components 15 respectively. Coils 14 are made, wherein two coils 14 respectively press the t...

Embodiment 2

[0070] like image 3 Shown, shuttlecock comprises ball head 11, ball skirt 12, ball skirt strut 13, reinforcement ring 14 and rotating member 15, and ball skirt 12 and ball skirt strut 13 are made of 15 or 16 artificial feathers.

[0071] The rotating member 15 is an independently formed member, including a bottle cap-shaped member and several rotating fins 152 . Nylon can be selected as the material for making the rotating member, and the production process of plastic injection molding is adopted. To save weight, the center of the bottom cover is pierced. There are 16 small round holes around the bottom of the cover, through which the ball skirt poles are inserted. This rotating component 15 is fastened on the ball head 11, and artificial feather and reinforcement ring 14 are installed then.

Embodiment 3

[0073] The shuttlecock of this embodiment comprises a ball head, a ball skirt, a ball skirt strut, a reinforcement ring and a rotating member.

[0074] like Figure 4Shown is the independently formed rotating member contained in the shuttlecock of the present invention, which includes a reinforcing ring 14 and a conical annular sheet body containing 16 inclined grooves. The bottom surface of the groove forms a low-level curved surface, and the sheet body forms a high-level curved surface. Two connecting walls are formed between the high-level surface and the low-level surface, that is, the left and right groove walls of the groove, one of which constitutes the above-mentioned rotational wind resistance. 153 walls. When the shuttlecock flies forward, the rotating wind resistance wall surface 153 is obliquely facing the air flow, forming wind resistance around the axis, and impels the shuttlecock to rotate around the axis. The shape, size, inclination angle and quantity of the...

Abstract

The invention relates to a novel badminton. The badminton contains an independent rotating component (15) which is not adhered to a badminton skirt (12), and the rotating component (15) has various kinds of structures, wherein, optimally the rotating component comprises a plurality of rotating wind resistance fins (152) or rotating wind resistance wall surfaces (153); and optimally the rotating wind resistance fins (152) or the rotating wind resistance wall surfaces (153) and the cross section of the badminton form an inclined angle (B) along an axis direction. The independent rotating component (15) has higher efficiency so as to more conveniently control weight, center-of-gravity position and weight distribution of the badminton; and the rotating component (15) and the badminton skirt (12) of the badminton can be respectively made into an independently molded fitting so as to enhance overall performance and facilitate production. The invention further relates to a badminton body containing the rotating component (15).

Description

technical field [0001] The invention relates to a shuttlecock and a shuttlecock body. Background technique [0002] Adopting artificial material to replace natural goose and duck feather to make shuttlecock is a long-term dream of industry circle and badminton sports circle. Because the playing resistance of the goose and duck feather shuttlecock is too poor, players frequently change the ball, and the cost of playing is greatly increased; meanwhile, the production process of the goose and duck feather shuttlecock is complicated, and the cost of the material itself is also relatively high. However, the technical difficulties hidden in this material replacement are by no means imagined by ordinary people. The industry has carried out relevant research work for more than 20 years, but so far, there is no shuttlecock made of artificial materials instead of goose and duck feathers, which has reached the level of high-quality goose and duck feather shuttlecocks in terms of compr...
