Description
Technical field
The present invention relates to a kind of soft-balls, more particularly to a kind of soft-ball of aerodynamic optimization.
Background technology
The difference of soft-ball and other traditional balls has：1, racket face is soft, and is that section is received, section batting is sent out
Ball.2, deficient gas is filled in ball, elasticity is far smaller than traditional ball, and notable shape inevitably occurs when being returned and being run for ball
Become.3, a certain amount of free sand grains is placed in ball, the addition of sand grains makes the center of gravity of ball be located in ball unlike traditional ball
The heart, ball due to the flowing of sand grains, can be such that the center of gravity of ball is subjected to displacement during exercise.But although on soft-ball and traditional ball have
Many differences are stated, traditional ball is but still followed in the outer surface contacted with air.
The present inventor has significant difference, simple edge with traditional ball by the discovery that studies for a long period of time, soft-ball in air force
Attack the problem of the soft-ball generally existing aerodynamic quality difference of traditional ball appearance.
Invention content
Present invention aims to overcome that the drawbacks described above of the prior art, provides a kind of soft-ball of aerodynamic optimization.
To achieve the above object, the soft-ball of aerodynamic optimization of the present invention is the soft-ball for having valve and built-in sand grains,
There are one arc bending dumbbell annular recess, the dumbbell annular recess to be separated on soft-ball surface up and down for the soft-ball surface system
It is stretched under the dumb-bell shape of equal docking and stretches flap on flap and dumb-bell shape.The soft-ball more specifically fills deficient gas.The arc bending
Dumbbell annular recess can guide air-flow and optimization air force in soft-ball operation.
As an optimization, it is described it is equal up and down be to be stretched under the dumb-bell shape after flap turns upside down, then rotated along central shaft
90 degree can be completely superposed with flap is stretched on the dumb-bell shape；It is stretched under the dumb-bell shape and stretches flap surface face on flap and dumb-bell shape
The valve of the different soft-balls of the identical either color of color, which is located to stretch under the dumb-bell shape, to be stretched on flap or dumb-bell shape in flap
The heart.
As an optimization, it is dark color that flap is stretched on the dumb-bell shape, and it is light color that flap surface color is stretched under the dumb-bell shape；It should
The valve of soft-ball is located on dark dumb-bell shape to stretch stretches flap center under flap center or light dumb-bell shape.
As an optimization, the soft-ball is to stretch flap under light dumb-bell shape made of light elastic plastic material and make inwards
The soft-ball matrix being made of the light dumb-bell shape Shang Shen flaps base and light arc bending dumbbell annular recess of light valve
It is stretched on light dumb-bell shape and stretches flap extexine on the compound layer depth color dumb-bell shape of flap base layer exterior surface.The elastic plastic material
Preferably elasticity PVC.
As an optimization, the soft-ball is stretched to stretch flap surface on flap and dumb-bell shape and be formed under the dumb-bell shape and uniformly be divided
The protrusion or pit of cloth.The pit is preferably more than triangle or triangle polygonal starlike, more preferably by center to four
Week gradually becomes shallower as, and more preferably intermediate is segment-shaped concave surface, and periphery is to shoal successively outward the arc to narrow along the radioactive ray of angle axis
Shape concave surface.
As an optimization, the protrusion is raised for the tufted being evenly spaced on.
As an optimization, the tufted protrusion is convex by three or three or more the linear fins of multiple acute angles or arrow-shaped
Rib；Or the linear fin of four or more alternatively distributed even number acute angle and arrow-shaped fin, head are common towards one
Central point and be circumferentially uniformly distributed middle combinate form tufted protrusion.The diameter of the tufted protrusion is preferably 4-8 millis
