Description
Technical field
What the present invention relates to is a kind of athletic sports appliance, is specifically a kind of badminton racket rod and manufacture method thereof.
Background technology
Badminton is one sports widely, for user, at the volley, a good racket is used to be very important, as used a bad racket, sense, mood impact is played greatly then on user, even can produce athletic injury, and is what racket good racket at last? speed is fast, high stability, strength conductive performance are good, the little racket of vibration of playing ball has been only racket.Industry is devoted to manufacture and design a kind of good racket beaten, to adapt to the needs of numerous users and badminton always.
Existing badminton racket rod (in also claiming pipe), its shape generally adopts hollow circular cylinder, when manufacturing and designing, hollow circular cylinder is adopt same material combination at length direction, the wall thickness of hollow circular cylinder is generally uniformity, adopt one-time formed technique to manufacture, therefore, its dabber is also uniformity in the performance such as rigidity, elasticity of length direction substantially.
Plumage claps the definition of turn-over point: plumage is clapped turn-over point and referred to that racket is in impact, and dabber bends the position of maximum point, and the length of turn-over point is the distance bending maximum point from frame head to dabber.
Existing badminton racket rod, racket in impact, the position of dabber turn-over point after racket batting generally at the middle part of dabber, under identical batting condition:
(1) dabber that rigidity is softer, because the deformation in the middle part of dabber after batting is larger, the turn-over point of dabber is longer from striking point on the ball distance, the angle that face is bending is comparatively large, and the time that face is replied is longer, and therefore racket striking speed is relatively slow, meanwhile, if when speed is replied in the bounce-back of clapping line after racket batting, shuttlecock will leave face and fly out, now shuttlecock cannot by means of the reply energy after power to dabber deformation;
(2) dabber that rigidity is harder, after batter's batting, deformation in the middle part of dabber is less, although the turnaround time of face is relatively very fast, because dabber rigidity is comparatively hard, the batting energy of batter effectively can not be absorbed by dabber, therefore the energy storage capability of dabber is poor, after batting, shuttlecock borrows the fault offset of power dabber less, thus causes striking speed comparatively slow, and cue power is poor.Meanwhile, the harder dabber power conduction of rigidity is relatively better, and the vibration therefore after racket batting will produce obvious feedback to batter, may cause athletic injury to batter.
Summary of the invention
Object of the present invention, a kind of badminton racket rod and manufacture method thereof that provide for above-mentioned weak point, this is adopted to invent the racket manufactured and designed, dabber turn-over point (middle combination) position after badminton racket rod batting can be set, by the setting of combination diverse location in dabber and dabber upper, middle and lower combination rigidity, regulate reply speed and the cue power of different qualities racket, design and manufacture the high-performance racket of applicable different play feature.
Use the racket that the present invention manufactures and designs, by the use of combination position high resiliency, high-toughness material in dabber, racket dabber ballistic properties is outstanding.
Use the racket that the present invention manufactures and designs, due to partially soft compared with other position of dabber with the rigidity of dabber turn-over point part (middle combination position), racket is divided into 2 parts from turn-over point part, 2 parts of racket are carried out (soft) by turn-over point part and are connected, racket has the impact principle of similar nunchakus (whip) after batting, racket head at square stance under the effect of inertia (centrifugal) power, cue power will strengthen, striking speed will be accelerated, after racket impact, the vibrations feedback of batter is obviously reduced, thus reduces athletic injury.
For achieving the above object, a kind of badminton racket rod of the present invention and manufacture method thereof take following technical scheme to realize:
The lower combination that middle combination, hollow circuit cylinder body outer surface that the upper combination that a kind of badminton racket rod comprises hollow circuit cylinder main body, hollow circuit cylinder body outer surface is combined closely, hollow circuit cylinder body outer surface are combined closely are combined closely.
Described hollow circuit cylinder main body, upper combination, middle combination, lower combination are combined closely the complete hollow circular cylinder of formation one, and its external diameter is consistent.
