Abstract
The utility model relates to a sport equipment technical field, have the racket of solid section promptly, wherein: part of the racket is a solid body of the same coating material, and part of the racket is a solid body of which the middle is a sandwich material and the periphery of the sandwich material is the coating material, which has the advantages that: firstly, do little with the section at racket solid position, reducible windage during the batting, it is more rapid to play the ball, makes user's batting power reduce relatively simultaneously, and indefatigability and batting are powerful, and secondly the racket frame body is less to the cross sectional area by the great excessive cross sectional area of cross sectional area, and the rigidity of framework also can be along with it softens gradually, and when the batting, the soft position of framework can produce great elastic deformation, and bounce can increase promptly to make the batting powerful, three the utility model discloses because of there is the position of pressing from both sides the core material in the middle of the selection arbitrary, the rigidity that can produce the framework has diversified racket, supplies more suitable colony to select.
Description
Technical field:
The utility model relates to technical field of sports apparatus, refers in particular to a kind of racket that has real core section of composite structure.
Background technology:
Traditional racket, comprise rackets such as tennis racket, wall ball racket, racket, time power bat, it generally all is hollow structure, it is very thin that this has just determined that the sectional thickness of racket can not be done, thereby can not reduce the air drag when playing ball well, the more weak or high resilience of rigidity that can not indiscriminately ad. as one wishes a part of racket be done.
Summary of the invention:
The purpose of this utility model overcomes the defective of prior art, the part of racket is made real cored structure body, reduce the area of section, thereby reduce the air drag of square stance, it is rapider, more favourable to use ball, simultaneously, reducing of the area of section, framework is reduced in the rigidity at this position, and elasticity increases, and batting more has restoring force.
The utility model is achieved in that the racket that has real core section, and the partial portion that it is characterized in that racket is the real core body of same clad material, and partial portion is that to enclose outside sandwich material, the sandwich material be the real core body of clad material for the centre.
On sandwich material can be arranged on the optional position of racket.
Above-mentioned clad material is fibrous composite or hard plastics or metal material.
Above-mentioned sandwich material is that PU material or other can be used for the packing material of external pressure machine-shaping.
The outstanding compared to existing technology advantage of the utility model is:
1, the section of the real core of racket position is done little, square stance can reduce windage, and it is rapider to go out ball, and user's strength of batting can be reduced relatively, and indefatigability and batting are strong.
2, the racket framework is big excessively less to the area of section by the area of section, and the rigidity of framework is deliquescing gradually thereupon also, works as square stance, and the soft position of framework can produce bigger strain, and promptly bounce can increase, thereby makes batting stronger.
3, the utility model is arbitrarily because of in the middle of selecting the position of sandwich material being arranged, and this has diversified racket with regard to having determined the rigidity that can produce framework, selects for the more colony that is fit to.
Description of drawings:
Fig. 1 is the structural front view of one of racket of not holding net mounting.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1, i.e. the cutaway view at the real core body position that makes of same clad material 1.
Fig. 3 is the B-B cutaway view Amplified image of Fig. 1, and promptly outside the real core body position that makes of same clad material 1: middle is the cutaway views at the real core body position that makes of clad material 1 for sandwich material 2, sandwich material 2 peripheries.
Fig. 4 is that the major part of the not racket head of holding net mounting is that sandwich material 2, sandwich material 2 peripheries are cutaway views of clad material 1 for the centre.
The specific embodiment:
With specific embodiment the utility model is further described below:
Referring to Fig. 1-4: have the racket of real core section, wherein: the partial portion of racket is the real core body of same clad material 1, and partial portion is that to enclose outside sandwich material 2, the sandwich material 2 be the real core body of clad material 1 for the centre.
Above-mentioned sandwich material 2 can be arranged on the optional position of racket.
Above-mentioned clad material 1 is fibrous composite or hard plastics or metal material.
Above-mentioned sandwich material 2 can be used for the packing material of external pressure machine-shaping for PU material or other.
During making, the position that is set with sandwich material 2 as shown in Figure 4, with selected PU expanded material as sandwich material 2, and produce laminboard layer, paste fibrous composite as clad material along the peripheral of laminboard layer and in conjunction with the shape bag of racket again, reenter the semi-finished product of the outer molded racquet frame body of mould, the half-finished first half of this racket framework is the real core of making of fibrous composite separately, the area of section is less, dress upper intermediate tube, handle, pull on netting twine, add the finished product that ornament materials promptly forms racket.
The utility model is applicable to various types of rackets such as making tennis racket, wall ball racket, racket, time power bat.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
Claims (4)
1, the racket that has real core section, the partial portion that it is characterized in that racket are the real core body of same clad material (1), and partial portion is that the centre is that to enclose outside sandwich material (2), the sandwich material (2) be the real core body of clad material (1).
2, the racket that has real core section according to claim 1 is characterized in that described sandwich material (2) can be arranged on the optional position of racket.
3, the racket that has real core section according to claim 1 is characterized in that described clad material (1) is fibrous composite or hard plastics or metal material.
4, the racket that has real core section according to claim 1 is characterized in that described sandwich material (2) can be used for the packing material of external pressure machine-shaping for PU material or other.
