Abstract

The utility model discloses a truncated structure of a racket frame, wherein the racket frame is provided with at least one hollow area with separated cross section. Furthermore the connection to the separated cross sections is realized through a cover plate. The cross sections are separate, and furthermore through the hollow area connected by the cover plate, the racket frame formed by high-polymer composite material has an easily deformed area, namely the racket frame with higher rigidity has certain deformation performance. Not only is rigidity of the racket frame reduced, but also the elasticity of the mesh wire is improved effectively. Furthermore the sweet point of the racket is enlarged. The ball controlling performance and ball hitting force of the racket are improved.

Description

The frame of racket amputated structure

Technical field

The utility model is about ball racket structures such as a kind of tennis, squash, plumage bats, is meant a kind of frame of racket amputated structure especially.

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 racket always, the power of playing ball with lifting, the comfort of ball-handling sense and hand.The zone of the effective deformation of wire side netting twine i.e. " sweet district ", is the key factor of decision racket ability of controlling the ball.

Racket is under the requirement of various parameters such as weight and intensity, develop into composite commonly used now from the most original wood materials, composite has the lighter relatively characteristics of intensity height, weight, but because different users has nothing in common with each other to the racket performance demands, but how to make the racket ability of controlling the ball better, this is that general user yearns for.

The utility model content

The purpose of this utility model is to provide a kind of can reduce the frame rigidity, improves the frame of racket amputated structure of racket ability of controlling the ball.

For achieving the above object, the technical solution of the utility model is:

A kind of frame of racket amputated structure wherein is provided with the vacancy section of at least one cross section dialysis on frame, and is realized the connection in dialysis cross section by cover plate.

Form the depressed area on the housing of the nearly two sections of described vacancy section, then to should vacancy section forming the cover plate of whole frame outer rim moulding, this cover plate just is fastened on the depressed area.

Described cover plate is polymer composite or resin material.

The upper surface middle part perfusion of described cover plate or adhesion one deck elastic layer are just stretched and are put between two sections.

Described elastic layer is located on cover plate and the surface that frame contacts.

Described elastic layer is a rubber layer.

After adopting such scheme, the vacancy section of the utility model by on frame, forming the cross section dialysis and connect by cover plate, can make the frame that forms by polymer composite have the zone of easy deformation, even the frame that rigidity is stronger has the certain deformation performance, not only reduced the rigidity of frame, and effectively increased the elasticity of netting twine, and then strengthened " the sweet district " of racket, improve the ability of controlling the ball and the batting dynamics of racket.

The increase of elastic layer also can further increase the damping capaicty of racket in addition, makes the serviceability of racket better.

Description of drawings

Fig. 1 is the front view of the utility model racket;

Fig. 2 is office's enlarged drawing of the utility model racket embodiment 1;

Fig. 3 is the decomposing schematic representation of structure shown in Figure 2;

Fig. 4 is the front view of the utility model racket embodiment 2.

The specific embodiment

Cooperate Fig. 1 to shown in Figure 4, a kind of frame of racket amputated structure that the utility model discloses, this racket is to make with polymer composite, the trigonum 3 that it comprises frame 1, lever 2 and connects frame 1 and lever 2; Key of the present utility model is: form at least one vacancy section 4 on frame of racket 1, this vacancy section 4 is in frame 1 local formation cross section dialysis, and by cover plate 5 adjacent section being linked together constitutes a complete frame 1.

Shown in Fig. 2,3, this vacancy section 4 is provided in a side of the bottom of frame 1, it is " 6 " some position of frame 1, form depressed area 42 on the housing of these vacancy section 4 nearly two sections 41, then to should vacancy section 4 moulding that form whole frame 1 form cover plate 5, it is holistic frame 1 that this cover plate 5 just is fastened on the depressed area 42 to form an outer margin contour, and wired hole simultaneously distributes on cover plate 5.When frame formed, this cover plate 5 was by the combination of netting twine realization with frame 1.

This cover plate 5 can adopt the polymer composite identical with frame 1, also can adopt resin material, so can increase the elasticity of whole frame 1.

In addition, at upper surface middle part perfusion or adhesion one deck elastic layer 6 of cover plate 5, this elastic layer 6 is just stretched and is put between two sections 41, and this elastic layer 6 is a rubber layer; Certainly this elastic layer 6 can only be located on cover plate 5 and the surface that frame 1 contacts.

Cooperate shown in Figure 4ly, the vacancy section 4 on the frame 1 can be located at the top of frame 1, i.e. " 12 " position.Or other position of frame 1, its purpose all is in order to realize the cross section dialysis of frame 1.

To sum up, the vacancy section 4 of the utility model by on frame 1, forming the cross section dialysis and connecting by cover plate 5, the zone that can make the frame 1 that forms by polymer composite have easy deformation, even the frame 1 that rigidity is stronger has the certain deformation performance, not only reduced the rigidity of frame 1, and effectively increased the elasticity of netting twine, and then strengthened " the sweet district " of racket, improve the ability of controlling the ball and the batting dynamics of racket; The increase of elastic layer 6 also can further increase the damping capaicty of racket in addition, makes the serviceability of racket better.
