Description

A kind of damping increases tennis racket, wall ball racket or the racket of bullet

1, technical field

The utility model relates to a kind of tennis racket, wall ball racket or racket, particularly relates to tennis racket, wall ball racket or racket that a kind of damping increases bullet.

2, background technology

Existing tennis racket, racket and wall ball racket along with the structure of scientific and technological progress racket particularly material be greatly improved, especially after having used staple fibre, the a lot of performances of racket are greatly improved, but several big problem that perplexs the user still is not well solved, comprising:

One, the racket batting is trembled and is caused the elbow injury, under four or five ten pounds of pulling force, netting twine elastic deformation stroke leeway is very little, and the elasticity of frame is littler, cause the impact of ball can not well cushion and feed back to ball, the energy that much trembles is delivered on the elbow, cause tennis elbow, cause the reason of trembling to be on the other hand, racket is after batting, clap the moment of line and frame recovery deformation, cause fierce reciprocal concussion, and this concussion need be held the line of frame and gives good buffering, this be why linear elasticity tremble well can be slightly little a reason, though can be by making the line made good use of and alleviating in a lot of measures of handle place cushioning beam, but its effect can not be satisfactory, the fact that easily causes tennis elbow that plays tennis does not still change, but also can cause the fuzzy feel that loses of ball seismaesthesia, on the whole, and the reciprocal concussion can not eliminate deformation recover time not high of existing exactly racket to the energy energy storage feedback efficient of ball cause the problem of tennis elbow, and be that the high more racket of poundage trembles big more.

Two, high resiliency and high control can not be compatible on a racket, no matter be tennis racket, racket or wall ball racket, if backguy poundage height, the line bed is hard, the power transmission of ball is also rapider in the time of batting, this causes controlling well, but loss is exactly elasticity, the soft property of return of serve energy storage and batting, it is also bigger to tremble in addition, the easier elbow that causes injures, if instead pursuit elasticity and racket feed back to the strength of ball, the poundage of corresponding minimizing backguy, the striking force transmission is slow, can reduce the controlled of ball, and these 2 can't method merge on a racket a lot of technology professional athlete bigger than higher force amount at present simultaneously, abandon high resiliency and security in order to pursue control, this also is the caving-in bash of attending to one thing and lose sight of another.

Three, the racket sweet district that bats is little, ball is beaten in off-centered slightly position, suppleness of bat just has very big drop, very easily cause error, especially it is littler that the speed of brandishing is fit to before the net the little face racket of the halting sweet district that bats soon, causing the batting difficulty to increase error increases, even adopt the increase in low its sweet district of backguy poundage also very limited, and the beginner sweet district causes for a short time when crossing the threshold that to dub be a big obstacle of grasping, this has also improved the threshold of study, influenced popularizing of motion, causing the little reason in the sweet district of batting is that feel is very hard because the elasticity of line bedside edge is very poor, if though increase the backguy poundage a lot of benefits are arranged, but sweet district can be littler, and this also is that poor people can not use one of high racket reason of backguy poundage.

But four, the racket that the backguy poundage is high control well the batting feel soft inadequately, be because the elastic deformation stroke of square stance line and frame causes for a short time, mainly be to improve behind the backguy poundage elasticity deficiency especially for increasing control, feel is just as a plank, feel is too hard, and it is too big to tremble, and a lot of players select for use the good natural gutstring of elasticity to alleviate the bad problem of high backguy poundage line bed elasticity, but its durability is low, and cost is too high can't be popularized with limited causing of result of use.

Five, batting can not be unified two kinds of performance requirements of frame, the high tenacity that requires on high strength that is flapped toward requirement on the racket direction of stroke and the racquet frame portion centripetal direction can not be unified on the frame of racket, be flapped toward and require square stance racket the integral body strength and the control of the little assurance batting of scope of deformation backward on the direction, frame will be got well to requirement toughness under high strength poundage pulling force on the mind-set direction, the square stance springing stroke is big under the prerequisite of height control like this, ball cushions, give the feedback strength of ball many, return of serve strength is big, racket trembles and also reduces relatively, because frame is integrated, if the material that working strength is very high satisfies the requirement of strength that is flapped toward on the direction, the toughness reguirements on the frame mind-set direction then can not be satisfied so, and frame is too hard, elasticity is bad, and vice versa.

Six, under the high backguy poundage situation, the impact that frame and bat line are subjected to is big, and frame is very big with the loss of clapping line, and this also is a main cause that causes the tennis cost high, and a lot of very expensive lines are not played just appearance damage of ball several times.

In addition, some innovations do not have the problem of radical change how many these existence yet: for example, the shock-absorbing bar of cushioning elastomeric material nail or mat between the online and frame of zl93221685.4, purpose is can increase good feel to a certain extent and increase a bit sweet district, reduction is trembled, but effect is very undesirable in the actual use of these pad materials, the very poor substantially effect of the elastic performance of these pad materials under high pressure is very little, the result does not make that how many raisings are the springing stroke of square stance obtain, and also just can not well deal with problems because increased this elastic mat; For another example, zl200620067909.x, spring shape journey is long and can make high-intensity deformation starting point, for minimizing tremble and increase big sweet zone all be beneficial to but its problem also clearly, the adding of spring will inevitably add the complicated structures of formation such as a lot of auxiliary parts such as line sleeve spring fixture, have influence on the reliability and the maintenance cost of use greatly, in addition, the thickness of spring is crossed conference and is caused the thickness of frame blocked up, windage increases excessive, also has the spring material generally mostly to be steel, can tolerate the firmly spring structure of more than 50 pound of pulling force, the above weight of general needs 3 grams, and the usage quantity of spring is many, and integral body is once heavy a lot, for the racket that has only about 300 grams, increase by tens spring members, can't accept simply; Also have, as prince ex03 series technique, add a large amount of vibration-absorptive materials and made the contacting still less of vibration-absorptive material and frame, this mode has reduced really trembles, increased sweet district, still this mode by thickening increasing damping flexible material finally causes the information fuzzy that trembles of batting, and feel is unintelligible, in comfortable, paid the cost of a large amount of losses of feel information, well settling mode.

More than analyze the situation that is applicable to tennis, wall ball racket and racket.
