Abstract

The utility model relates to the technical field of sports appliance, namely a racket with a spring device. A spring which is able to strain the net line 5 to the external side of the head frame is arranged between the head frame of the racket and net line at the external side of the head frame. The external side of the spring is provided with a cover which is tightly pressed against the spring through net line. The utility model has advantages that: firstly, when balls exert the force on the net line of the racket, the distortion of the net line will strain the spring to increase the distortion displacement so as to form the bigger bouncing force, thus making ball hit more forcibly; secondly, the vibration of the net line because of ball hitting can be absorbed by spring and converted into potential energy, which can lower the vibration of transmitted to players' hands, thus lowering sports hurt and playing the effect of vibration prevention and absorption; lastly, the utility model is suitable for various types of rackets such as tennis ball racket and squash racket.

Description

The racket of band spring assembly

Technical field:

The utility model relates to technical field of sports apparatus, refers in particular to a kind of racket that adds spring assembly on framework.

Background technology:

Traditional racket, generally after pulling netting twine, the netting twine pulling force directly acts on the racket framework, the elastic force of netting twine has directly determined the bounce of racket, when ball impacts on the netting twine at racket, telescopic displacement by netting twine self produces elastic force, because the stroke of netting twine is limited, make the screen resilience of racket be subjected to certain restriction, because screen resilience is little, cause also can not get alleviating significantly, thereby easily cause the tired even injury of athletic arm by the shaking force that racket is transmitted on the human body.

Summary of the invention:

The purpose of this utility model provides a kind of racket with spring assembly, shifts vibration energy by spring, improves the screen resilience of racket to ball, reduces the vibration influence that racket causes human body, improves the quality and the level of ball game.

The utility model is achieved in that the racket of band spring assembly, it is characterized in that in that be provided with on the racket head framework and between the netting twine of the external side of headers box can be with the spring of netting twine 5 to the tension of the external side of headers box, arranged outside at spring has cover plate, leans on netting twine with cover plate and spring compression.

Above-mentioned spring can be provided with on any root netting twine on the racket head framework.

Above-mentioned cover plate is full slice system or multiple-piece, and cover plate is made by fibrous composite or plastic material or metal material or hard rubber material.

The section shape that adds the shock mount position on the above-mentioned framework is " C " shape, and opening is laid spring, cover plate outwardly in the opening, and uses the netting twine fastening.

When above-mentioned spring was assembled, netting twine can pass from spring eye.

Above-mentioned racket head framework is the structure of the structure of the real core of part, part strap clamp core or the real core of part, part hollow, part strap clamp core.

The outstanding compared to existing technology advantage of the utility model is:

1, when ball impacts on the netting twine that acts on racket, netting twine stress deformation meeting back-moving spring causes the deformation displacement amount on racket of netting twine to strengthen, thereby forms bigger bounce, makes batting stronger.

2, can be absorbed and change into potential energy by spring when ball impacts the shock energy that is produced on the netting twine that acts on racket, be transmitted to human body vibrations on hand, reduce athletic injury, play the effect of shock-absorbing, shock-absorbing thereby can weaken.

3, the utility model is applicable to various types of rackets such as making tennis racket, wall ball racket.

The specific embodiment:

With specific embodiment the utility model is further described below:

Referring to Fig. 1-6: the racket of band spring assembly, it is characterized in that in that be provided with on the racket head framework 3 and between the netting twine 5 in head framework 3 outsides can be with the spring 1 of netting twine 5 to head framework 3 outsides tensions, arranged outside at spring 1 has cover plate 2, by netting twine 5 cover plate 2 and spring 1 is compressed.

Above-mentioned spring 1 can be provided with on any root netting twine 5 on the racket head framework 3.

Above-mentioned cover plate 2 is full slice system or multiple-piece, and cover plate 2 is made by fibrous composite or plastic material or metal material or hard rubber material.

The section shape that adds shock mount 1 position on the above-mentioned framework 3 is " C " shape, and opening is laid spring 1, cover plate 2 outwardly in the opening, and with netting twine 5 fastenings.

When above-mentioned spring 1 was assembled, netting twine 5 can pass from spring eye.

Making of the present utility model: referring to Fig. 1-9: make sandwich 6 earlier, adding core material selects for use PU expanded material or other lightweight plastic cement etc. to have the material making of fillibility, on core 6, cover fibrous composite bag card again, zone in the head framework 3 that spring 1 will be set is all pasted by the composite wood material package, and formation C type structure, reenter outer molded the forming of mould and be racket frame, during backguy, needing the position mounting spring 1 of mounting spring 1, again by dress cover plate 2 and backguy, the placement location of spring 1 can pass from the axis of spring 1 by netting twine shown in Figure 25, and netting twine can be by the orthoscopic mode backguy of Fig. 8 wire-jumper type or Fig. 9.

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.
