By above analysis as can be known,, the elasticity of this part is increased, effective usable floor area of wire side is increased, thereby significantly enlarge the sweet district of batting if can increase the effective length of racket edge netting twine.
The utility model content
The purpose of this utility model is to provide a kind of effective length that increases the edge netting twine, to enlarge the novel racket in the sweet district of batting.
For achieving the above object, technical solution of the present utility model is: a kind of novel racket, and its frame comprises a frame, trigonum and handle, the periphery of a frame has the line hole to constitute wire side; Be provided with the hollow out parallel in the trigonum with the root that a frame connects, and the line hole direction of this position of frame is parallel with netting twine with wire side.
The line hole direction and longitudinal network line parallel or parallel of described frame and trigonum link position with horizontal netting twine.
The inside casing boring ratio housing hole in the line hole of described frame and trigonum link position is big.
Be provided with the nail pipe in the described line hole, and this nail pipe is for the spike pipe of a protrusion frame inner rim or for not protruding the short nail pipe of a frame inner rim.
After adopting such scheme, because the utility model is made as hollow out at the trigonum root, therefore this position of a frame no longer is subjected to the interference of two side, trigonum, the line hole direction that open in this place also no longer is restricted, when making line hole direction parallel with netting twine, netting twine herein can be parallel mobile when the batting distortion, thereby make the effective length lengthening of netting twine, so just can improve the batting dynamics; Cooperate the parallel design in racket head frame other parts netting twine and line hole again, effective usable floor area of wire side is increased, make the sweet district of batting of racket enlarge 15-20%.
In addition, the utility model is compared with known techniques and is also had following advantage:
1, the utility model descends the rigidity of trigonum owing to the design of trigonum root hollow out, and at square stance, the deformation of a frame is less, and the deformation of trigonum is bigger, therefore can prolong the time of contact of ball and netting twine, has so just increased the dynamics of square stance.
2, the utility model can be further with a frame 5 '/7 ' the line hole be set as the big structure in inside casing boring ratio housing hole, the vertical deformation amount of two edges netting twine will be strengthened, even the lengthening of netting twine effective length herein, and not as known racket, the netting twine vertical deformation only in inner rim with internal strain, thereby can increase the ball time on the net effectively, make the rebound velocity of ball faster, promptly batting is stronger.
