Description

The changeable type elastic force shock-absorbing handle of tennis racket

The utility model relates to the changeable type elastic force shock-absorbing handle of tennis racket.

Usually, the physical characteristic of tennis racket, except that weight, equilbrium position, length, grip size etc., also having a kind of very important physical characteristic is the rigidity of this racket, the height of rigidity has influence on batting power, batting sensation and ball-handling.Just generally speaking, the demand of racket rigidity is varied with each individual, the someone gets used to harder racket, also has the people to like slightly soft racket, so the racket of being sold on the market is hard-soft, can choose according to individual's demand.But, the consumer more wish the racket that oneself uses can according to the different of place or other need and adjust its rigidity come in response to.

The purpose of this utility model is promptly providing a kind of changeable type elastic force shock-absorbing handle of tennis racket, needing and adjust its rigidity according to the different of place or other.

For reaching above-mentioned purpose, solution of the present utility model is:

Have a free end that engages with handle on the frame, this free ending tool is gradient, and have one along central shaft to through hole; Handle has and corresponding engagement ramp of frame and seat surface, also is provided with a hole on this seat surface; Ask on frame and handle composition surface and to be lined with a cushion pad; Lock member comprises bolt, spring body, nut and packing ring, and spring body, packing ring are nested with on bolt, and bolt passes the through hole of frame, the hole of handle seat surface, with the locking of nut, frame and handle is combined closely.

Wherein, spring body can place in the handle, also can place the crotch on the frame free end.

Above-mentioned cushion pad and protractile one can cover the endless belt of frame and the outer naked wire of handle joint.

Behind the employing said structure, the utility model can be adjusted the rigidity of racket by adjusting the pressing degree of bolt locking, and the user can need and adjust it according to the different of place or other.In addition, the utlity model has a cushion pad, can effectively block seismic wave and be passed to handle, spring body then can effectively reduce square stance, and the reaction force that arm bears avoids producing the athletic injury that is commonly called as " tennis elbow ".

Below in conjunction with drawings and Examples, the utility model is described in detail.

Fig. 1 is the utility model embodiment one structural representation;

Fig. 2 is the plane exploded view of the utility model embodiment one;

Fig. 3 is the utility model embodiment two structural representations;

Fig. 4 is the plane exploded view of the utility model embodiment two.

Shown in Fig. 1-4, have a free end 11 that engages with handle 2 on the frame 1 of the present utility model, this free end 11 has suitable gradient 12, and have one can for bolt 41 run through along central shaft to through hole 13.

Handle 2 has free end 11 corresponding engagement ramp 21 and the seat surfaces 22 with frame 1, also is provided with a hole 23 on this seat surface 22.

Be lined with a cushion pad 3 between frame 1 and handle 2 composition surfaces, this cushion pad 3 and overhanging endless belt 31 are to cover the outer naked wire that frame 1 and handle 2 engage.

Lock member 4 comprises bolt 41, spring body 42, nut 43 and packing ring 44, spring body 42, packing ring 44 are nested with on bolt 41, bolt 41 passes the through hole 13 of frame 1, the hole 23 of handle 2 seat surfaces 22, then with the locking of nut 43, frame 1 and handle 2 is combined closely.Wherein, shown in Fig. 1-2, spring body 42 is to place in the handle 2, and bolt 41 passes through hole 13, the hole 23 of handle 2 seat surfaces 22, the spring body 42 of packing ring 44, frame 1 in regular turn, then with the locking of nut 43; As shown in Figure 3-4, spring body 42 is the crotches that place on frame 1 free end 11, and bolt 41 passes through hole 13, the hole 23 of handle 2 seat surfaces 22, the packing ring 44 of packing ring 44, spring body 42, frame 1 in regular turn, then with the locking of nut 43; The effect of two embodiment is identical.

Like this, the utility model is because the restoring force of spring body 42 continues to have the strength that links closely to act on frame 1 and the handle 2, make it shock-proof effect just like the automatic shock-proof device, can adjust the deflection of this spring body 42 simultaneously by the locking degree of adjusting bolt 41, just adjust the strength that this links closely, reach the purpose of adjusting the racket rigidity, in addition, because frame 1 has a cushion pad 3 with handle 2 composition surfaces, so, the vibration wave that is produced after frame 1 is impacted is intercepted major part and can't be passed to handle 2, moreover, spring body 42 its effects just like the automatic shock-proof device, hit on dessert even fail, also will be because of the shock-proof effect of spring body 42, the reaction force that arm is experienced is reduced to minimum level, avoids athletic injury effectively.
