Description

Structure of badminton, badminton ball head and feather

The present invention provides a structure of badminton, badminton ball head and feather, especially relates to a badminton ball head. The badminton ball head includes a feather arrangement device, and the feather arrangement device has at least one preset insertion cavity. To plant feathers.

The crown of the badminton ball head is an effective hitting area of the badminton. The quality of the ball crown directly affects the feel of the badminton and the service life of the ball head.

The crown of a traditional badminton ball head is made of natural cork or natural cork shavings and glue, and then it is formed by wrapping a layer of leather with natural cork or natural cork shavings. The limited resources of natural cork have resulted in higher prices for badminton made from natural cork. In addition, due to the rapid loss of badminton, the general public cannot afford the price of badminton using natural cork, which further affects the popularity of badminton.

On the other hand, ball heads that are glued with natural cork chips need to be glued. The surface of the natural cork chips has a layer of dust, which prevents the direct contact between the natural cork grain skin and the adhesive, which reduces the degree of adhesion. After being hit repeatedly, the ball head is prone to softness due to insufficient adhesion, so the service life of the ball head is low.

Further, in order to enable the badminton to fly in rotation, when the feathers are inserted into the ball head, they are arranged side by side in a superimposed manner, so that the feathers form a vortex. To make the badminton flight smooth, the overlapping parts of the feathers need to be as consistent as possible. In other words, the consistency of feather insertion into the ball head is high. In traditional badminton, in order to insert feathers into the badminton head, Head drill jack. It is usually a small circular socket, and the cross-section of the feather stem is square. Therefore, when the feather is inserted into the round socket, it is difficult to control the consistency of the insertion direction of the feather stem of each feather.

If the ball head is made of natural cork, the ball head is easily deformed during the drilling of the jack, so that the shape of the hole changes. In other words, the socket is not enough to provide a stable clamping force to fix the stalk of the feather inserted into the socket, thereby forming a hollow ball head. If the ball head is made of natural cork chips, during the drilling of the jack, the cork chips will easily cause the inner wall of the jack to fall, so that the jack cannot provide sufficient pressure to be applied to the badminton stem to fix it. Feather, this may cause the badminton to be easily damaged, and the quality of the badminton will be reduced.

Further, in order to enable the badminton to rotate and fly, when the feathers are inserted into the ball head, the feathers are formed in a sideways dislocation and superimposed manner to make the feathers vortex. In other words, each feather will have an eccentric angle, and there will be a certain gap between the two pieces of adjacent feathers. In order to ensure the stable flight of badminton, the clearance must be as same as possible. In traditional badminton, the natural badminton stems are directly connected to the ball head. The jack on the ball head is not easy to set into the shape of a feathered stem. It is also difficult to set the eccentric angle of the jack, so it is difficult to control each feather The angle of the eccentric angle makes the difference between the eccentric angles large, and eventually leads to poor flight stability of the shuttlecock. The shape of the jack does not match the shape of the feather's stalk. That is, there is a gap between the feather stems and the jack. When the ball head is hit, the force on the hitting part of the ball head will be transmitted to the feather stems, causing the feather stems to squeeze the groove wall of the jack, and then the jack and feather stems. The gap between them becomes larger. After the gap between the socket and the feather stalk becomes larger, the function of the jack to fix the feather stalk is weakened, causing the feather to easily detach from the ball head. Further, the transmission of force by the hairy stems is unbalanced, and it is easy to cause partial hairy stems to break, thereby shortening the service life of the shuttlecock.

After the feather of a traditional badminton is inserted into the ball head, the surface of the hair stem is coated with glue to fix it. Since the glue is applied to the surface, the amount of glue applied to a certain extent determines the firmness of the hair stem, but there is too much glue. This will increase the weight of badminton.

Further, in order to fix the feather to the ball head, glue is applied to the joint of the feather stem and the ball head. Because coated glue is not easy to quantify, badminton is often overweight. And the bonding surface is mainly concentrated at the contact position of the hair stem and the jack port, and the interior can only be bonded by the infiltrating glue, so the bonding is unstable. On the other hand, the joint of the glue-coated stalk and the ball head is harder than the part without the glue, so the joint of the glue-coated stalk and the ball head is prone to fracture, which weakens the feather stalk. It is connected to the ball head, so that the feather stems are easily detached from the ball head, which affects the flight stability of the shuttlecock.

Further, the natural feathers used in badminton, such as duck feathers and goose feathers, and traditional badminton, on the one hand, to ensure the basic flight characteristics of badminton, external feathers need to meet a predetermined length, on the other hand, to ensure the stability of installation, The longer ends of the hairy stalks need to be inserted into the cork ball head, which makes the required feather length longer. For natural feathers, the length varies, and a longer range of feathers can be selected, which is one of the reasons why the price of badminton is higher.
