Problems solved by technology

However, this inevitably leads to a reduction in the torsional performance and rigidity of the front end of the mid tube
Therefore, the badminton racket of this prior art attempts to change the outer diameter of middle tube to improve the effect of its bending performance is very limited.
Furthermore, as mentioned earlier, such prior art mid-pipes are difficult to machine

Embodiment Construction

[0024] Such as figure 2 As shown, the badminton racket 30 of the present invention includes a middle tube 32 , a head frame 34 and a handle 36 . Wherein the head frame 34 is connected to the front end 321 of the middle tube, and is used for passing through the net wire to form the net surface 38 for hitting the ball; the handle 36 is connected to the rear end 322 of the middle tube.

[0025] combine image 3 It can be seen that the middle tube 32 is designed as a tubular shape with a uniform outer diameter and has a hollow inner cavity 323, so that the front end and the rear end of the middle tube of the present invention generally maintain the same torsional performance. Here, the outer diameter D is the size required by the standard, ie 7.0mm or 7.5mm. The wall thickness t of the middle tube 32 gradually decreases from the rear end 322 to the front end 321 , so that the inner cavity 323 is conical. Since the wall thickness t of the middle tube 32 gradually decreases from...

Abstract

The invention discloses a battledore, which comprises a medium tube, a head box connected to the front end of the medium end, and a handle connected to the rear end of the medium tube, wherein the medium tube is in a tubular shape with a consistent external diameter, and the wall thickness of the medium tube is gradually reduced from the rear end to the front end. The battledore of the invention changes the wall thickness of the medium tube to cause a buckling point of the medium tube to move upwards so as to increase the arm of force while swinging the battledore, thus being capable of magnifying the hitting strength. In addition, the wall thickness of the medium tube is gradually reduced from the rear end to the front end, thereby being capable of flexibly controlling the hitting angle and being beneficial to magnifying the hitting strength.

Description

technical field [0001] The present invention relates to badminton rackets. Background technique [0002] A badminton racket generally consists of a middle tube, a head frame connected to the front end of the middle tube, and a handle connected to the rear end of the middle tube, wherein the head frame is used to pass through the network cable to form a net surface. [0003] In existing badminton rackets, the middle tube is mostly in the shape of a uniform and straight circular tube. Under the same premise of other conditions, the larger the outer diameter of the middle tube, the higher its rigidity, and the greater the strength when swinging the racket; on the contrary, the smaller the outer diameter of the middle tube, the better and easier it is to bend Hit the ball at a tricky angle, but its stiffness is low, so hard hits can cause the mid tube to buckle. In addition, the position of the bending point on the center tube will also affect the power of hitting the ball and...
