Abstract

The utility model provides a badminton racket with adjustable attack force and elastic hardness of the middle tube. An axial sliding part is built in the elastic point of the middle tube of the badminton racket. The sliding part is in the shape of a hard hollow tube. A section of cavity is set between the sliding part and the top end of the racket middle tube, and a slider with a certain weight is set in the cavity, which can slide in the cavity. Because the length of the elastic point of the middle tube is moved forward, the length of the moment arm is shortened to speed up the hitting reaction speed and increase the strength, which requires the player to have greater explosive power. The opposite is true when the elastic point is moved backward. The best hit for explosive power. When the golfer hits the ball and swings the racket, the slider in the middle tube slides toward the head of the racket to reach the top of the middle tube or the top of the slider, thereby changing the center of gravity of the racket, increasing the weight of the racket head, and increasing the hitting power. And it can save money by reducing the purchase of rackets.

Description

Badminton racket with adjustable attack strength and elastic hardness of the middle tube

technical field

The utility model relates to the technical field of sports calcining equipment, in particular to a badminton racket with adjustable attack strength and elastic hardness of a middle tube.

Background technique

Badminton racket in the prior art is to be made up of three main parts of threaded frame, middle pipe, handle. Rackets with good elasticity in the center tube are loved by players, but due to the different players' individual qualities, the explosive power when hitting the ball is also different. For the same racket, different players may feel that the center tube of the racket is soft or hard. Hitting effect. At the same time, according to the different choices of golfers, it is also necessary to increase the attack power.

The solution of the prior art is to produce rackets with different elastic tubes in multiple models for selection. Even so, due to technical reasons, the elasticity of the middle tube of each racket of the same model cannot be exactly the same. Players can only know whether it is suitable for them in actual use. And the change of the player's physical fitness and skill will also cause the original racket to no longer suit him.

Utility model content

The purpose of this utility model is to design a badminton racket with adjustable attack strength and elastic hardness of the middle tube, which can adjust the elasticity of the middle tube to a certain extent by adjusting the position of the elastic point of the middle tube of the badminton racket and changing the hardness of the middle rod. To increase the power of hitting the ball, the sliding weight-increasing parts are designed.

An axial sliding part is built in the elastic point of the middle tube of the badminton racket. The sliding part is in the shape of a hard hollow tube. A cavity is set between the sliding part in the middle tube and the top end of the racket middle tube. A slider with a certain weight is arranged in the cavity, which can slide in the cavity.

Or, there is a built-in axial sliding part with a certain length at the elastic point of the middle tube of the badminton racket. The sliding part is in the shape of a hard hollow tube coaxial with the middle tube. A slider with a certain weight is arranged in the part, which can slide in the hollow part.

There is a through hole in the center of the slider. The slider can slide with damping in its sliding cavity. The sliding piece is connected to the adjustment part of the handle part by the connecting rod at the lower end, and the adjusting part makes the sliding piece axially move in the middle tube through the connecting rod through thread adjustment. On the badminton racket handle there is an indicating part and an indicating mark corresponding to the adjustment part. An axially sliding part is built in the elastic point of the middle tube of the badminton racket and coincides with the inner cavity of the middle tube. Through the axial movement of the slider in the middle tube, the elastic point of the middle tube is forced to move back and forth within a certain range (the movement of the slider is completed by a component built in the handle that converts the rotational force into the axial movement force, and the adjustment part can It is a mechanical device or an electrical device.

The utility model has the advantages that: the preferred mechanical driving mode, and there is an indicator mark at the bottom of the handle, and the parts connected with the adjustment part can also be in other forms or in other positions. Because the length of the elastic point of the middle tube is moved forward, the length of the moment arm is shortened to speed up the hitting reaction speed and increase the strength, which requires the player to have greater explosive power. The opposite is true when the elastic point is moved backward. The best hit for explosive power. When the golfer hits the ball and swings the racket, the slider in the middle tube slides toward the head of the racket to reach the top of the middle tube or the top of the slider, thereby changing the center of gravity of the racket, increasing the weight of the racket head, and increasing the hitting power. And can reduce buying racket thereby save money.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Example 1

An axial sliding part is built in the elastic point of the middle tube 7 of the badminton racket. The sliding part is in the shape of a hard hollow tube, and a section of cavity is set between the sliding part 6 in the middle tube 7 and the top of the racket middle tube , a slider 8 with a certain weight is set in the cavity, which can slide in the cavity.

Example 2

Or, there is a built-in axial sliding part with a certain length at the elastic point of the middle tube of the badminton racket. The sliding part is in the shape of a hard hollow tube coaxial with the middle tube. A slider with a certain weight is arranged in the part, which can slide in the hollow part.

In the above two embodiments, there is a through hole in the center of the slider. The slider can slide with damping in its sliding cavity. The sliding piece is connected to the adjustment part of the handle part by the connecting rod at the lower end, and the adjusting part makes the sliding piece axially move in the middle tube through the connecting rod through thread adjustment. On the badminton racket handle there is an indicating part and an indicating mark corresponding to the adjustment part. An axially sliding part is built in the elastic point of the middle tube of the badminton racket and coincides with the inner cavity of the middle tube. Through the axial movement of the slider in the middle tube, the elastic point of the middle tube is forced to move back and forth within a certain range (the movement of the slider is completed by a component built in the handle that converts the rotational force into the axial movement force, and the adjustment part can It is a mechanical device, and it can also be an electrical device. The preferred mechanical drive mode of this program has an indicator mark at the bottom of the handle, and the parts connected with the adjustment part can also be in other forms or in other positions). Because the length of the elastic point of the middle tube is moved forward, the length of the moment arm is shortened to speed up the hitting reaction speed and increase the strength, which requires the player to have greater explosive power. The opposite is true when the elastic point is moved backward. The best hit for explosive power. When the golfer hits the ball and swings the racket, the slider in the middle tube slides toward the head of the racket to reach the top of the middle tube or the top of the slider, thereby changing the center of gravity of the racket, increasing the weight of the racket head, and increasing the hitting power.

As shown in Figure 1-3, by rotating the knob 1 on the bottom bracket 2, the component 3 that converts the rotational force into an axial movement force is driven by the connecting rod 5 to drive the sliding part 6 in the middle tube to move axially in the middle tube 7, to change the position of the elastic point of the middle tube. When swinging the racket, the sliding block also slides in its cavity to change the center of gravity and increase the power of swinging the racket.
