Abstract

The utility model discloses badminton rackets with middle pipe improving structures. Each badminton racket comprises a racket handle, a middle pipe and a racket frame, wherein one end of the middle pipe is connected with the racket handle, and the other end is connected with the racket frame; the middle pipe is a hollow pipe body, and the outer peripheral surface of the section is circular. The inner peripheral surface of the section of at least one segment of the middle pipe is non-circular and symmetrical up and down or left and right. When the badminton rackets are in processing, the implementing and positioning are convenient so that the up-and-down or left-and-right symmetrical stability in production can be improved, thereby greatly reducing difference in wall thickness uniformity caused in grinding of the outer peripheral surface of a pipe fitting and achieving the effect of improving the playing sense of the badminton rackets.

Description

The structure improved racket of pipe in a kind of tool

Technical field

The utility model relates to the racket field, relates to the structure improved racket of pipe in a kind of tool in particular.

Background technology

Badminton is because of easy to learn and be not subjected to advantage such as place restriction, and extremely people from all walks of life's favor; As the racket of badminton core equipment, quality of itself and professional degree then become orders about the principal element that the badminton fan buys.

As shown in Figure 1, existing racket 9 generally comprises handle 91, middle pipe 92 and frame 93, and this handle 91 grips for the user; Should play the connection effect by 92 of middle pipes, the one end links to each other with handle 91, and the other end then links to each other with frame 93; Be formed with wire side on this frame 93, realize impacting shuttlecock by this wire side and shuttlecock effect.

An important parameter in racket 9 professional is played sense exactly, and influences racket 9 rerum naturas and beat the key factor felt just at middle pipe 92; Shown in Figure 1A, the middle pipe 92 of existing racket 9 all is the pipe fitting of hollow generally, and the inside and outside side face 922,921 of pipe fitting section is concentric circles, and promptly outer peripheral face 921 and inner peripheral surface 922 are all presented down left and right sides mirror image symmetrical circular and concentric circles each other.Manage 92 in the racket 9 of this quasi-tradition, rerum natura is except general rigidity according to the use material is just classified, the quality of its quality mainly is the uniformity that is subjected to its pipe thickness, just the out of roundness of hollow pipe fitting and concentricity decide, so whether very big to the influence of its quality the processing procedure stability of production firm is, but, the procedure for producing ability of present industry, can't further promote its stability more, carry out particular design so be necessary to rely on centering pipe 92, avoid or to reduce procedure for producing stability not enough and bring the influence on the quality.

The utility model content

The purpose of this utility model is to provide the structure improved racket of pipe in a kind of tool, and it can be beneficial to the location in the work in-process control journey, and promotes symmetrical up and down and symmetrical stability in the production.

In order to reach above-mentioned purpose, solution of the present utility model is:

The structure improved racket of pipe comprises handle, middle pipe and frame in a kind of tool, and this one end of the central tube links to each other with handle, and the other end then links to each other with frame; Should in pipe for hollow tube, and the outer peripheral face of section is circle, wherein, in this in pipe the inner peripheral surface of at least one section section be symmetrical or symmetrical non-circular up and down.

Described non-circular for major axis is not equal to the ellipse of minor axis, this major axis be positioned at top and bottom or about face.

Described non-circular be runway shape, this runway shape have the top and bottom of being arranged on or about face and be symmetrically arranged planar section.

In described in the pipe at least one section be connected with the frame partial section of an end of middle pipe.

In described in the pipe at least one section be connected with the handle partial section of an end of middle pipe.

At least one section centre portion that is not close to frame or handle for middle pipe in the pipe in described.

After adopting said structure, the structure improved racket of pipe in a kind of tool that the utility model relates to, wherein at least one section section inner peripheral surface is non-circular in the pipe, so add man-hour at processing procedure, can be convenient to realize the location, thereby can promote symmetry or symmetrical stability up and down aborning, thereby reduce the evenness of wall thickness difference that produces when the pipe fitting outer peripheral face grinds greatly, and then reach the effect that the lifting shuttlecock is patted sense.Concrete, the utility model can be chosen in the different section settings of middle pipe according to the difference characteristics of batting and be non-circular, thereby can effectively satisfy the different demands of intensity or the lifting of torsion aspect, and then enriches the product line demand of racket.

The specific embodiment

The utility model is elaborated by specific embodiment below in conjunction with accompanying drawing.

Pipe 2 structure improved rackets 100 in a kind of tool that the utility model relates to, it comprises handle 1, middle pipe 2 and frame 3, and pipe 2 one ends link to each other with handle 1 in this, and the other end then links to each other with frame 3; Should in pipe 2 be hollow tube, and the outer peripheral face 21 of section is circle, above-mentioned feature is identical with racket of the prior art 100, so no longer be described in detail, below improvement of the present utility model is described in detail:

Main improvement of the present utility model is: in this in pipe 2 inner peripheral surface 22 of at least one section section be symmetry or symmetrical non-circular up and down.Like this, add man-hour at processing procedure, can be convenient to realize the location, thereby can promote symmetry or symmetrical stability up and down aborning, reduce the evenness of wall thickness difference that produces when pipe fitting outer peripheral face 21 grinds greatly, and then reach the effect that promotes 100 dozens of senses of racket.

Concrete, the utility model can be chosen in middle pipe 2 different section settings according to the difference characteristics of batting and be non-circular, thereby can effectively satisfy the different demands of intensity or the lifting of torsion aspect, and then enriches the product line demand of racket.

Shown in Fig. 2 A, inner peripheral surface 22 shapes of pipe 2 sections can be set to the ellipse that major axis is not equal to minor axis in this, and this major axis is positioned at top and bottom; Shown in Fig. 2 B, in this pipe 2 sections inner peripheral surface 22 shapes can be set to the ellipse that major axis is not equal to minor axis, and this major axis be positioned at about face; Shown in Fig. 2 C, inner peripheral surface 22 shapes of pipe 2 sections can be set to runway shape in this, and this runway shape has the top and bottom of being arranged on and is symmetrically arranged planar section; Shown in Fig. 2 D, inner peripheral surface 22 shapes of pipe 2 sections can be set to runway shape in this, and this runway shape have be arranged on about face and be symmetrically arranged planar section.Certainly, inner peripheral surface 22 shapes of pipe 2 sections are not limited to above-mentioned four kinds of situations in this, can also be other, so long as non-circular getting final product.

Shown in Fig. 3, Fig. 3 A, Fig. 3 B and Fig. 3 C, described in the pipe 2 at least one section be connected with frame 3 partial section of an end of middle pipe 2.

Shown in Fig. 4, Fig. 4 A, Fig. 4 B and Fig. 4 C, described in the pipe 2 at least one section be connected with handle 1 partial section of an end of middle pipe 2.

Shown in Fig. 5, Fig. 5 A, Fig. 5 B and Fig. 5 C, at least one section centre portion that is not close to frame 3 or handle 1 for middle pipe 2 in the described middle pipe 2.

The foregoing description and graphic only be specific embodiments of the present utility model, allly utilize this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
