Abstract
The utility model discloses a kind of double crowned section frames and rackets, including outline border and inside casing, the hollow annular body of rod is collectively formed in outline border and inside casing, is provided with outer domes on outline border, interior domes are provided on inside casing, outer domes and interior domes collectively constitute double domes.Double crowned section rackets of the utility model, the outline border of domes can increase the stability and tensile strength of frame entirety, and the inside casing of domes can increase the effective hitting range of racket；The frame section of double arches can reduce the whole size of frame under the premise of not reducing racket effective hitting range, to make that racket has the characteristics that lightweight and intensity is high.
Description
Technical field
The utility model relates to a kind of badminton racket frame more particularly to a kind of double crowned section frames and racket.
Background technique
Existing racket is mainly made of accessories such as frame, middle pipe, protheca and handles, many consumers or sportsman
There is light-weighted demand to racket.Existing racket lightweight scheme generally comprises following several: first is that reducing ball
The usage amount of the carbon fiber of frame and middle pipe is patted, second is that reducing the whole size of frame, reduces frame area.
But the scheme for reducing carbon fiber usage amount will lead to the remitted its fury of racket, anti-fight power reduces, and influences
The durability degree and durability of racket；Although the scheme for reducing frame is little to the intensity effect of racket, can reduce
The effective hitting range of racket, influences racket balling effect.
Summary of the invention
The utility model provides a kind of double crowned section frames and racket, can guarantee racket intensity
Under the premise of, realize the lightweight of racket.Specific technical solution is as follows:
The hollow annular body of rod is collectively formed in a kind of double crowned section frames, including outline border and inside casing, outline border and inside casing, outside
It is provided with outer domes on frame, interior domes are provided on inside casing, outer domes and interior domes collectively constitute double
Domes.
Further, outer domes are arc-shaped, and the protrusion of arc protrudes setting to the direction far from frame center.
Further, interior domes are arc-shaped, and the protrusion of arc protrudes setting to the direction far from frame center.
Further, the both ends of outer domes are connected with the both ends of interior domes, and connecting portion is smooth circular arc
Structure, so that outer domes and interior domes group domes in pairs.
Further, the entirety of frame is disposed as double domes.
Further, the local setting of frame is double domes.
Further, including single domes, single domes and double domes are arranged at intervals on frame.
Further, the outline border of single domes is outer domes.
Further, the inside casing of single domes is interior domes.
A kind of racket, including frame, frame lower end are connected with middle pipe, and middle pipe lower end is connected with lever, and feature exists
In frame is above-mentioned double crowned section frames
Double crowned section frames and racket of the utility model, the outline border of domes can increase frame entirety
The inside casing of stability and tensile strength, domes can increase the effective hitting range of racket；The frame of double arches
Section can reduce the whole size of frame, so that racket be made to have under the premise of not reducing racket effective hitting range
Lightweight and the high feature of intensity.
Detailed description of the invention
Fig. 1 is the perspective view of the section structure of double crowned section frames of the utility model.
Fig. 2 is the cross-section diagram of double crowned section frames of the utility model.
Fig. 3 is schematic diagram of the line bed in double crowned section frames of the utility model to outline border generation pulling force.
Specific embodiment
In order to be best understood from the purpose of this utility model, function and specific design scheme, with reference to the accompanying drawing to this
The double crowned section frames and racket of utility model are described in further detail.
The racket of the utility model includes frame, middle pipe and handle, and one end of middle pipe is connected with frame, the other end
It is connected with handle, wherein frame is double crowned section frames.Frame is the hollow annular body of rod, is provided with intersection in frame
The cable of arrangement.Frame is surrounded jointly by outline border and inside casing, as shown in Figure 1, outer domes 1 are provided on outline border, on inside casing
It is provided with interior domes 2.
Outer domes 1 are arc-shaped, and the protrusion of arc protrudes setting to the direction far from frame center；Interior domes
2 is also arc-shaped, and the protrusion of arc protrudes setting to the direction far from frame center.The both ends of outer domes 1 and interior arch
The both ends of structure 2 are connected, and connecting portion is seamlessly transitted using arc structure, so that frame section forms shown in Fig. 2 pair
Domes.
Outer domes 1 are equipped with cable-through hole with interior domes 2, and the cable of racket passes through the mistake on interior domes 2
String holes is fixedly connected with the cable-through hole on outer domes 1.As shown in figure 3, shuttlecock impact is when on racket, cable can be right
Outer domes 1 generate inside pulling force F, and since outer domes 1 are domed, the protrusion of arch has stronger rigidity,
It is able to bear biggish pulling force and is unlikely to deform.Therefore, outer domes 1 can be such that the frame of racket imitates with stronger load
Fruit improves the intensity and durability degree of badminton racket frame.
Cable area inside interior domes 2 is the sweet spot of racket.When the protuberance of interior domes 2
When portion's curvature is bigger, then the sweet spot of racket can be made to increase under the premise of not changing frame entirety size.
That is, interior domes 2 under the premise of not reducing sweet spot, can be such that the overall dimensions of outline border reduce, reach diminution
Frame area makes the light-weighted effect of racket.And the arcuate in shape of interior domes 2 also can be improved the intensity of frame.
The frame of racket can be integrally using the double arches collectively formed by outer domes 1 and interior domes 2
Structure can also be double domes with local setting.When the local setting of frame is double domes, other positions are settable
For single domes.Single domes can be with are as follows: outline border is set as outer domes 1, and inside casing is ordinary construction；Inside casing is set as
Outer domes 1, outline border are ordinary construction.Single domes and double domes intervals are arranged, it is preferable that single domes with
The central axes of double domes pipe in are symmetrical arranged.
Double crowned section frames and racket of the utility model, the outline border of domes can increase frame entirety
The inside casing of stability and tensile strength, domes can increase the effective hitting range of racket；The frame of double arches
Section can reduce the whole size of frame, so that racket be made to have under the premise of not reducing racket effective hitting range
Lightweight and the high feature of intensity.
The utility model is further described by specific embodiment above, it should be understood that, have here
The description of body, should not be construed as the restriction to the spirit and scope of the utility model, and one of ordinary skilled in the art is readding
The various modifications made after reader specification to above-described embodiment belong to the range that the utility model is protected.
