Abstract

The utility model discloses a rocket frame structure, wherein hollowed holes are molded on a part outside a line channel of a racket of a rocket frame. Because the hollowed holes are molded on the rocket frame, the fiber trend of the whole rocket frame can not be cut off and the strength of the rocket frame can be ensured. Simultaneously, because of the hollowed design, the weight of the whole rocket frame is reduced. The hollowed holes can reduce wind resistance when the rocket is swung, can enhance the speed of swinging the rocket and can enhance the strength of hitting a ball.

Description

A kind of frame structure

Technical field

The utility model is about ball frame structures such as a kind of tennis, squash, plumage bats.

Background technology

Tennis, squash, impacting property such as plumage bat are ball to be a kind of elegance, the sports of the body-building that the scope of application is extensive, can temper hand, pin, eye, each coordination ability partly of healths such as brain, reaching body and mind simultaneously loosens, strengthen the effect of physique, but what it the most directly had an effect batting is arm, if the design of racket is improper, or the posture of swinging the bat of playing ball is not right, then can directly pass to arm because of the anti-volatilization power and the shock wave of square stance, ache for a long time and produce arm, promptly be commonly called as the motion phenomenon of " tennis elbow ", the dealer is devoted to improve the structural design of frame of racket always, the power of playing ball with lifting, the comfort of ball-handling sense and hand.

Frame of racket is under the requirement of various parameters such as weight and intensity, develop into composite frame commonly used now from the most original wooden frame, composite has the lighter relatively characteristics of intensity height, weight, but because different users has nothing in common with each other to the requirement of frame weight, but how to make frame lightweight more, to promote the speed of batting, this also is that general user yearns for.

The utility model content

The purpose of this utility model is to provide a kind of can reduce windage and light-weighted frame structure.

For achieving the above object, technical solution of the present utility model is: a kind of frame structure, wherein the part beyond the racket duct of frame forms the hole of hollow out.

The hole of described hollow out only is molded over the part of frame head.

The hole of described hollow out is molded over the middle pipe place of frame.

The positive cut-out openings in pipe place in the described frame.

Guan Chu side cut-out openings in the described frame.

The hole of described hollow out is to be molded on the whole frame.

Described hole is that the outer wall by frame connects to inwall.

After adopting such scheme, because the part of frame of racket of the present utility model beyond its racket duct forms the hole of hollow out, and the hole of this hollow out is to be molded on the frame, and then the fiber orientation of whole frame can not blocked, and can guarantee the intensity of frame, simultaneously, because of the design of its hollow out, the weight of whole frame is reduced greatly, and the hole of hollow out can reduce the windage when swinging the bat again, improve the speed of swinging the bat, promote the dynamics of batting.

The specific embodiment

As shown in Figure 1, 2, frame structure of the present utility model, this frame 1 is by composite material forming, it has the cavity of hollow, wherein the part beyond the racket duct 11 of this frame 1 forms the hole 12 that connects with cavity, during moulding, this hole 12 connects moulding by the outer wall of frame 1 to inwall, makes whole frame 1 visually have the design of hollow out.

The hole 12 of this perforation can be distributed in whole frame 1, also can be distributed in the part of frame 1, as the triangle portion 14 of frame 1 head, 13 both sides or frame 1.

Because of the hole 12 of this hollow out is one-body molded on frame 1, thereby the fiber orientation of whole frame 1 can not blocked, and the frame of whole hollow out is similar to steel frame construction, and it has enough intensity, thereby can guarantee the support strength of frame; Simultaneously, the design of frame 1 hollow out the weight of whole frame 1 is reduced greatly, and the hole 12 of hollow out can reduce the windage of the frame when swinging the bat, and improves the speed of swinging the bat, and promotes the dynamics of batting.

Shown in Fig. 3,4, the hole 12 of this hollow out is not only the head that is molded over frame 1, and is also plastic at middle pipe 15 places of frame 1, and this hole 12 can be in the positive hollow out (see figure 3) of middle pipe 15; Also can so also can reduce the weight of frame 1, promote the dynamics of batting in the two sides of middle pipe 15 hollow out (see figure 4).

Shown in Fig. 5,6,7,8,8A, the frame structure of this hollow out design, it is not only applicable to tennis racket, also can reach the hole 11 that forms hollow out on the badminton racquet frame 1 on the frame 1 of the squash that various tool dynamics require, and it has practicality and progressive effect equally.
