Abstract

The utility model relates to a shuttlecock, comprising a shuttlecock head and a connecting rod which is circularly arranged on the shuttlecock head and extends backward. The front segment of the connecting rod is provided with a ring which is perpendicular to the connecting rod. The rear part of the connecting rod is a wing part. The utility model is characterized in that the wing part is provided with piece-shaped connecting strips which extend obliquely and are provided with proper spaces. One side of a cross section of a connecting strip is horizontal. The other side is provided with an oblique angle. Because the connecting strips at the wing part of the utility model are respectively provided with an oblique plane, the utility model can work with air through the oblique planes, produces pressure difference, drives the shuttlecock rotating, stabilizes flight routes, and enhances flight speed. The utility model is suitable for various recreations and competitions.

Description

Badminton

The utility model relates to a kind of shuttlecock, particularly about the improvement of shuttlecock assistant.

Existing shuttlecock (as shown in Figure 1), establishing bulb 2 by skeleton 1 and skeleton one end forms, this skeleton 1 comprises around the connecting rod 3 that is provided with and is arranged on connecting rod 3 ends and be netted assistant 4, and when the striker dishes out shuttlecock when hitting bulb 2, shuttlecock bears air drag flight.Because two contained sides, 31 equal in length (as shown in Figure 2) of the connecting rod 3 of existing shuttlecock, therefore when being hit, shuttlecock flies when contacting with air, air equates the active force that connecting rod 3 two contained sides 31 produce, and shuttlecock flight the time is subjected to the influence of sinuous flow in the air, very easily produces the unsettled situation of flight.Again because the pore 41 that netted assistant 4 forms is irregular alignment, cause air that the pore 41 that shuttlecock assistant 4 forms is irregular alignment, cause air also unequal to the active force that shuttlecock assistant 4 produces, vacillating and staggering and speed is slow or unstable during flight, have a strong impact on the carrying out of this motion.

Also has a kind of shuttlecock now, the connecting rod 5 of forming skeleton, the length unequal (as shown in Figure 3) of its cross section two contained sides 51,52, flight aloft after shuttlecock is hit, air is done the time spent to the contained side of 5 two different lengths of connecting rod, and long contained side 51 is stressed less, short contained side 52 is stressed bigger, therefore produce a pressure differential, promote the shuttlecock rotation, so that shuttlecock forms stable flight path.Yet this shuttlecock only improves connecting rod 5 parts, and this part be in the connecting rod near the zone in axle center, by connecting rod to the axle center the formed arm of force very short, very little to the turning effort that shuttlecock produced.Moreover, see that on the whole connecting rod 5 sections two contained sides 51,52 only are a bit of near bulb 2, the rotary thrust that can produce is very limited, so shuttlecock can't rotate effectively, reaches the purpose of stabilized flight.

In view of all deficiencies of above-mentioned existence, the purpose of this utility model provide a kind of can be effectively by air pressure, promote the shuttlecock rotation and stablize the shuttlecock of its flight path.

For achieving the above object, the utility model is taked following design: a kind of shuttlecock, it comprises badminton head, be located on the connecting rod that extends back on it, described connecting rod leading portion is provided with the ring vertical with described connecting rod, and described connecting rod rear portion is the assistant position, it is characterized in that: the sheet that described assistant position is provided with oblique extension and tool appropriate intervals connects bar, the described cross section that connects bar is level on one side, and another side has gradient.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As shown in Figure 4, badminton head 20 is equipped with several connecting rods that extend back 10, be provided with the vertical ring 12 of some and connecting rod 10 along connecting rod 10 leading portions, the zone that connecting rod 10 and ring 12 are surrounded forms bigger pore 14, at connecting rod 10 back segments are assistant positions 16, be provided with several sheets that are oblique extension and the narrow and small interval 19 of tool and connect bar 18 between the pore 14 ' at assistant position.As shown in Figure 5, from connecing the cross section of bar 18, on one side it is plane 182, another side is the inclined plane 181 that opposite planar 182 has suitable gradient.

When the striker up dishes out shuttlecock, when hitting badminton head 20 with racket, shuttlecock is promptly towards airflight, pore 14 usefulness that shuttlecock has are passed through to reduce the resistance of air for air, it can be landed smoothly, when air passes through the netted assistant position 16 of shuttlecock, can produce active forces by butt strap 18.As shown in Figure 5, when gas molecule connects bar, along the inclined plane the 181 gas molecule M speed of passing through along the plane the 182 gas molecule N speed of passing through fast, the inclined plane 181 that connects bar 18 is born different pressure respectively with plane 182, therefore promptly produce a pressure differential, the bar 18 that connects that circular row distributes forms a continuous pressure differential afterwards with the air interaction, forces the shuttlecock rotation, reaches the purpose of stablizing its flight path, improving flying speed.

The utility model is owing to take above design, it has the following advantages: 1, because the bar 18 that connects at assistant of the present utility model position 16 is provided with an inclined plane 181, can be by it and gas effect, produce pressure reduction and rotate to promote shuttlecock, and because the distance L of assistant position 16 and central shaft₁Than the distance L of connecting rod in the prior art 5 to central shaft₂Be length (as shown in Figure 6), so it is long than the arm of force of prior art to promote the arm of force of shuttlecock rotation, effect is better than prior art. 2, owing to of the present utility modelly connect the assistant position 16 that bar 18 circular rows are distributed in shuttlecock, area distributions is wide, and the shuttlecock of prior art only connecting rod 5 is designed gradient with air effect, relative the utility model of power that gained promotes the shuttlecock rotation is little, promote the shuttlecock rotation so the utility model obviously more can be brought into play, stablize the effect of its flight path.

Claims (1)

1, a kind of shuttlecock, it comprises badminton head, be located on the connecting rod that extends back on it, described connecting rod leading portion is provided with the ring vertical with described connecting rod, described connecting rod rear portion is the assistant position, it is characterized in that: the sheet that described assistant position is provided with oblique extension and tool appropriate intervals connects bar, and the described cross section that connects bar is level on one side, and another side has gradient.
