Description
Technical field
The present invention relates to sporting goods fields more particularly to a kind of racket and preparation method thereof.
Background technology
At present, either professional sportsman or amateur, for bodies such as tennis racket, racket and wall ball rackets
Articles for use are educated to be intended to pursue light-weight effect, under the premise of guarantee is light-weight, bat must also have certain intensity, this
The two is often the demand of conflict, herein mainly with tennis racket for example, as shown in Figure 1, tennis racket generally has hand
Handle 1, frame portion 3 connect bending section 2b, 2a of handle 1 and frame portion 3, and as shown in Fig. 2, tennis racket since at handle, by two
Hollow tubular product A1, A2 of extension form the right part of handle, continue extension two hollow tubular products formed right bending section A11, A22,
Continue two hollow tubular products that extension curves and form frame portion（Do not show in figure）, continue two hollow tubular products curving of extension and form a left side
Bending section B11, B22, continue left part B1, B2 that two hollow tubular products extended form handle, two hollow tubular products are about in net
The positions such as 5 points, 7 points, 11 points and 1 point of racket（This is the dialect of tennis racket circle, simulates clock face to show tennis racket surface frame
The corresponding position in portion）It is tied up with special material and covers fixation.As shown in figure 3, it looks along the section view in A'-A' directions（Obtain Fig. 4）、
It looks along the section view in B'-B' directions（Fig. 5 is obtained, shown in Fig. 5, in the position without pass through cable, two hollow tubular product walls
3C is positioned against together）, as shown in figure 4, the frame portion includes 3B on the outside of frame portion inside 3A and frame portion, that is arranged in frame portion 3 wears
String holes 3D is reserved between two hollow tubular product wall 3C for wearing the space of cable, this space is thick in making tennis racket
Metal shaft is put between two hollow tubular product wall 3C during base, extracts metal shaft out again after shaping, has just been obtained corresponding
Threading hole, still, the positions such as 5 points, 7 points, 11 points and 1 point in tennis racket, since adjacent two-by-two on these positions is worn
The direction for the line that string holes passes through is orthogonal, when making tennis racket crude green body, in following threading hole position adjacent two-by-two
Put, be not used in be put between two hollow tubular product wall 3C metal shaft, etc. after moldings the method for extraction metal shaft come
Normal threading hole is formed, because two metal shafts can collide overlapping, has both made to make frame portion reluctantly, the threading of these positions
Hole is also that gross distortion does not conform to checkerwork cell, then, must just wait carbon fibre materials harden after again by external force the 5 of tennis racket
Point, 7 points, the positions drilling such as 11 points and 1 point, then cable could be passed through plus thread-protected tube in these holes, with ensure cable not by
The sharp keen cinclides edge of bore position is worn, for example, the intensity of carbon fiber is about 5 times of steel or so, if at one
It drills on the carbon fiber face hardened of plane, hole edge edge is necessarily sharp, in this way, will be increased using thread-protected tube
The total weight of tennis racket, and the processing technology of entire tennis racket is more complicated.Moreover, because manufactured using two pipes,
In order to ensure the light and handy of weight, the wall thickness of two pipes is artificially reduced, the problem of wall thickness strip comes is the intensity difference of racket.
To overcome the problems, such as aforementioned weight, people start to make tennis racket with single tube, as shown in fig. 6, a hollow tube
Material forms the right part 1a of handle, and the hollow tubular product for continuing extension forms right bending section 2a, continues the hollow tubular product shape that extension curves

As shown in Fig. 9,10,11,12, the tubing of racket punches again after curing, obtains outside eyelet and inside eyelet D',
Outside eyelet and inside eyelet D' will appear sharp angular eyelet trim along F, and this eyelet trim edge is also relatively rough, therefore,
After cable E' passes through this eyelet, due to eyelet edge F to be contacted, the eyelet trim shown in particularly Figure 10 is being used along F
During tennis racket, eyelet trim belongs to along F at stress, and line is in flexible and anxiety replaces with what is relaxed with contact of the eyelet trim along F
It can constantly be worn, cable E' is just easy to break, as being usually to have 72 threading holes on tennis racket, as long as being cut there are one threading hole
Cable E' or even cable E' fractures, entire wire side will lose tension, not play a part of to impact tennis.Therefore, people in order to
The service life of line E' is improved, as shown in figure 12, thread-protected tube H is added at eyelet, thread-protected tube can be simple grain（Suitable for feather
Racket）Or rows of spike（Suitable for tennis racket）Cable E' is kept apart with eyelet trim along F.But by institute
Some has the angular eyelet trim of wedge angle that will add thread-protected tube along the eyelet of F, and it not is one that all thread-protected tube weight, which adds up,
Decimal fractions, the weight of racket still cannot mitigate to reach ideal light and handy state.For example, the carbon in China's Mainland
Monthly sales volume is about 500,000 to the tennis racket of Fiber Materials, and the weight of the thread-protected tube material of every tennis racket shield line is about
25 grams, then, annual to need with the material weight on thread-protected tube to be 15 kilograms, value is about 9,000,000 RMB.Less use
Say that the net ball top of sales volume bigger is clapped.It that is to say, racket weight of the prior art is not ideal enough, and consumptive material is more.
