Description

Technical Field

[0001] The utility model relates to the technical field of sports goods, and particularly relates to a novel middle rod structure of a badminton racket. Background Art

[0002] At present, most of the middle rod parts of badminton rackets are carbon fiber tubular structures. The middle rod made of carbon fiber has good elasticity and light weight. However, due to different carbon fiber materials and different production processes of prepreg, the rebound speed and toughness performance of a simple carbon fiber middle rod are not necessarily very excellent, and it is very difficult to adjust the bending position and degree of the middle rod after being stressed with a single carbon fiber material. Therefore, it is necessary to design a novel middle rod structure to make up for this shortcoming. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a novel middle rod structure of a badminton racket. By adding an alloy tube into the middle rod main body and using resin between the inner and outer walls of the middle rod main body and the alloy tube to enable them to be fully combined, and through the high elasticity and high toughness characteristics of the alloy tube, the rebound speed and toughness of the middle rod main body are greatly increased, so as to achieve the purpose of reducing deformation, increasing the power transmission efficiency, and reducing the recovery time after the racket hits the ball, so as to solve the above deficiencies in the technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical scheme: a novel middle rod structure of a badminton racket, including:

[0005] A middle rod main body, an alloy tube is arranged inside the middle rod main body, and a resin interlayer is arranged between the inner wall of the middle rod main body and the outer wall of the alloy tube.

[0006] Preferably, the alloy tube is a nickel-titanium alloy tube or a niobium-titanium alloy tube, and a thickened wall is arranged at one section of the inner wall of the alloy tube.

[0007] In the above technical scheme, the technical effects and advantages provided by the utility model are:

[0008] By adding an alloy tube into the middle rod main body and using resin between the inner and outer walls of the middle rod main body and the alloy tube to enable them to be fully combined, and through the high elasticity and high toughness characteristics of the alloy tube, the rebound speed and toughness of the middle rod main body are greatly increased, so as to achieve the purpose of reducing deformation, increasing the power transmission efficiency, and reducing the recovery time after the racket hits the ball, and a thickened wall is arranged at a certain section inside the alloy tube to set different wall thicknesses separately, and by adjusting the wall thicknesses at different positions of the alloy tube, the deformation state of the whole middle rod main body when stressed can be adjusted.

[0014] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0015] The present utility model provides a novel middle rod structure of a badminton racket as Figure 1 - Figure 2 shown, including:

[0016] A middle rod main body 1, an alloy tube 2 is arranged inside the middle rod main body 1, and a resin interlayer 3 is arranged between the inner wall of the middle rod main body 1 and the outer wall of the alloy tube 2.

[0017] The alloy tube 2 is a nickel-titanium alloy tube or a niobium-titanium alloy tube.

[0018] After the middle rod main body 1 made of traditional carbon fiber material is formed, a nickel-titanium or niobium-titanium alloy tube that fits its inner diameter can be added to the inner wall of the tube, and a resin material is filled between its inner and outer walls to form a resin interlayer 3, so that the inner wall of the middle rod main body 1 and the outer wall of the alloy tube 2 can be fully combined;

[0019] Due to the high elasticity and high toughness characteristics of the alloy tube 2, the rebound speed and toughness of the middle rod main body 1 are greatly increased, so as to achieve the purpose of reducing deformation, increasing the power transmission efficiency, and reducing the recovery time after the racket hits the ball.

[0020] A thickened wall 4 is arranged at one section of the inner wall of the alloy tube 2.

[0021] The wall thickness of the alloy tube 2 can be adjusted according to the overall hardness of the middle rod body 1 as required. At the same time, a thickened wall 4 can be set in a certain section of the alloy tube 2 to set different wall thicknesses separately. By adjusting the wall thickness of different positions of the alloy tube 2, the deformation state of the entire middle rod body 1 when subjected to force can be adjusted. In addition, the design length of the alloy tube 2 can also be determined based on whether it is necessary to adjust the bending point of the middle rod body 1 after being subjected to force, to determine whether to make the entire length or a part of the length.

[0022] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
