Special-purpose feather-planting frame for shuttlecock and shuttlecock

Abstract

The invention relates to a special feather-planting frame for badminton, comprising a hair-planting tube (21) and a connecting rod (22), characterized in that an independently formed reinforcing ring ( twenty four). The upper and lower edges of the reinforcing ring (24) are respectively provided with several outward lower protrusions (241) and upper protrusions (243). When the reinforcing ring (24) is installed in place, the upper and lower protrusions just block the connecting shaft (22). Another solution is that part or whole of the reinforcing ring (24) is embedded in the matrix of the connecting rod (22). The present invention also relates to a shuttlecock using the special hair-planting frame for the shuttlecock.

Description

technical field [0001] The invention relates to a special hair-planting frame for shuttlecocks and shuttlecocks. Background technique [0002] Adopting artificial material to replace natural goose and duck feather to make shuttlecock is an ideal 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. From the public information, it can be found that in the 1960s, there were patent applications related to artificial material shuttlecocks, such as Zhao 36-19067 published on Showa 36.10.12 (October 12, 1961). Later, there were patent applications for ind...

Problems solved by technology

However, there are many disadvantages when used on ball skirt poles made of artificial materials: first, the artificial feathers that appear at present are generally made of plastic material, and the surface is relatively smooth, unlike poultry feathers that have burrs, so the coils are easy to slip; Second, the stems of the artificial feathers (that is, the ball skirt rods) are relatively thin, the distance between the two feather stems is relatively large, and the artificial feather stems are relatively soft. These factors lead to the fact that the strength of the conventional coils is not enough to support the ball when smashing. The skirt is deformed, especially when the racket hits the coil directly, the coil is easily damaged; third, the production process of adding glue to the coil is too complicated

This scheme is applied to shuttlecocks made of artificial feathers according to traditional techniques, and its effect is not as good as that applied to the wool planting rack scheme
