Abstract

A handle of a battledore is made of composite materials, and comprises an outer pipe, an inner pipe and a rib part, wherein, the inner pipe is arranged in the outer pipe coaxially; the top end of the inner pipe is connected with the top end of the outer pipe; and the rib part is connected with the outer pipe and the inner pipe. Therefore, the handle has the advantages that the weight of the handle can be reduced; the structural strength of the handle is enhanced; the batting smoothness can be enhanced; and the occurrence of sport injuries can be reduced.

Description

The lever of Badminton racket

Technical field

The utility model is relevant with Badminton racket, is meant a kind of lever of Badminton racket especially.

Background technology

The lever of general Badminton racket is solid wooden structure, and its top is drilled with the shrinkage pool of a desired depth, supplies the axis of Badminton racket to plug and fix.

Yet, because of lever is solid structure but not hollow structure, so lever has quite heavy weight.Thus, when the user brandishes the Badminton racket of using this lever, be subjected to the weight influence of lever easily and can't bat swimmingly, even may cause the athletic injury of user's wrist.

The utility model content

Main purpose of the present utility model is to provide a kind of lever of Badminton racket, and it is in light weight, and the structural strength height makes and uses the smooth degree and the generation of avoiding athletic injury that Badminton racket of the present utility model can increase batting.

Take off purpose for before reaching, the lever of Badminton racket provided by the utility model is made by composite, include Guan Yuyi flank in the outer tube,, wherein this outer tube has the body portion that a head and of expanding gradually from top to bottom is straight tube-like, should be located at coaxially in this outer tube by interior pipe, and connect the apical head of this outer tube with its top, and this flank connect this outer tube with should in pipe.

The beneficial effects of the utility model are:

Use this made lever of composite to have lightweight characteristics, and pass through the design of this flank, can increase the structural strength of this lever, application Badminton racket of the present utility model is had concurrently simultaneously increases batting smooth degree and the advantage of avoiding moving injury.

Description of drawings

In order more to understand characteristics of the present utility model place, be described as follows below in conjunction with two preferred embodiments and conjunction with figs., wherein:

Fig. 1 is the partial sectional view of the utility model first preferred embodiment.

Fig. 2 is the cutaway view of Fig. 1 along the 2-2 hatching line.

Fig. 3 is the cutaway view of Fig. 1 along the 3-3 hatching line.

Fig. 4 is the cutaway view of the utility model second preferred embodiment.

Fig. 5 is the cutaway view of the utility model the 3rd preferred embodiment.

Fig. 6 is the cutaway view of the utility model the 4th preferred embodiment.

The specific embodiment

See also Fig. 1 to Fig. 3, the lever 10 of the Badminton racket that is provided for the utility model one preferred embodiment includes pipe 30 and one flanks 40 in the outer tube 20.Lever 10 is made by composite, and as fibre reinforced resin, fiber can be carbon fiber, glass fibre, boron fibre or Ke Weila (Kevlar) fiber, and resin can be thermoplastic resin or thermosetting resin.

When making, fiber stringing with two pre-soaked resins is provided with side by side earlier, insert again in the mould and heat, make these fiber stringing sclerosis form outer tube 20, wherein the interconnective position of these fiber stringings forms flank 40, pipe 30 in the position that these fiber stringings are separated from each other then forms.

On structure, outer tube 20 has the body portion 24 that a head 22 and of from top to bottom expanding gradually is straight tube-like, and the outer peripheral face of body portion 24 can twine for a belt for handle (not shown).

In pipe 30 be located at coaxially in the outer tube 20, and connect head 22 tops of outer tube 20 with its top, can plug for an axis (not shown) of Badminton racket.

Flank 40 is that the inwall by outer tube 20 extends, and pipe 30 in connecting, and makes flank 40 that outer tube 20 inside are separated into left and right two empty chambers 26.The parallel in fact outer tube 20 of the bearing of trend of flank 40 is axial with interior pipe 30.Certainly, flank 40 also can be separated into outer tube 20 inside upper and lower two empty chambers 26, as shown in Figure 4; Perhaps utilize three formed three flanks 40 of fiber stringing that outer tube 20 inside are divided into three empty chambers 26, as shown in Figure 5.

Because lever 10 of the present utility model is by the made body of composite, can alleviate many weight than existing solid wooden structure, flank 40 between outer tube 20 and interior pipe 30 has then been strengthened the structural strength of lever 10, overall weight that make to use Badminton racket of the present utility model can effectively be reduced and can not had influence on structural strength, in order to increase the smooth degree of square stance, can avoid the generation of athletic injury simultaneously.

Based on spirit of the present utility model, the structure of lever also can have multiple variation pattern.See also Fig. 6, the lever 50 that is provided for the utility model the 4th preferred embodiment, a shock suction body 62 is installed on the top of interior pipe 60 again, shock suction body 62 is to be made by rubber-like plastics or rubber material, as soft thermoplastic rubber (thermoplastic rubber), polyurethane (PU), block polyether vinegar amine (PEBAX) etc., in order to absorb the vibrations that the square stance axis transmits.The structural change that every these easy full of beard reach all should be claim scope of the present utility model and contains.
