Abstract

The utility model discloses a golf ball relates to the sports goods field, and the diameter of this golf ball's shell is 4.9mm, and the equilateral circular arc triangle -shaped's of a plurality of triangle recess is evenly arranged on the surface of shell, and the inside of shell is equipped with the spherical ball core of circle, be equipped with the intermediate level between ball core and the shell, and the intermediate level is netted. The triangle recess has fully utilized aerodynamic, makes the torrent change and twists the emergence, the difficult flow separation phenomenon that takes place of turbulent boundary layer to make spheroid low -pressure area behind one's back little, reduced the resistance, make the distance increase of golf ball flight. Certain space is left in can making golf ball in reticular intermediate level, has increased golf ball's elasticity, can effectively increase hitting of golf ball and beat the distance.

Description

A kind of golf

Technical field

The utility model relates to sports goods field, particularly a kind of golf.

Background technology

Golf is a kind of ball game that enters cave with shank, and the shape of golf is one of achievement of aerodynamic studies. The Transitional And Turbulent Flow that this streams with spheroid and separated flow phenomenon are relevant, and golf ball surface has had a mind to manufacture many indentures.

The indenture of existing golf ball surface is designed to circle mostly, and the flying distance of golf is limited, particularly, in the time that wind is large, can seriously shorten the flying distance of golf.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of golf, opens the triangle groove of some equilateral circular triangles at the outer shell of golf, to improve the flying distance of golf.

For achieving the above object, the utility model provides following technical scheme: a kind of golf, it is characterized in that: described golf comprises spherical shell, the diameter of shell is 4.9mm, the surface uniform of shell is furnished with the triangle groove of several equilateral circular triangles, the inside of shell is provided with the ball core of spheroidal, between ball core and shell, is provided with intermediate layer, and intermediate layer is netted.

Preferably, described shell is manufactured by carbamate, and the thickness of shell is between 1.2-1.5mm.

Preferably, described intermediate layer is manufactured by EP rubbers.

Preferably, described ball core is manufactured by ACM.

Adopt the beneficial effect of above technical scheme to be: the diameter of the shell of this golf is 4.9mm, the surface uniform of shell is furnished with the triangle groove of several equilateral circular triangles, the inside of shell is provided with the ball core of spheroidal, between ball core and shell, is provided with intermediate layer, and intermediate layer is netted. Triangle groove has fully used aerodynamics, impels Transitional And Turbulent Flow to occur, and turbulent boundary layer is difficult for flow separation phenomenon occurs, thereby makes spheroid low-pressure area behind little, has reduced resistance, and the distance of golf ball flight is increased. Netted intermediate layer can make to leave certain space in golf, has increased the elasticity of golf, can effectively increase the distance that impacts of golf.

Brief description of the drawings

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Fig. 1 is the structural representation of a kind of golf of the utility model;

Fig. 2 is the internal structure schematic diagram of a kind of golf of the utility model.

Wherein, 1-shell, 2-intermediate layer, 3-ball core, 4-triangle groove.

Detailed description of the invention

Describe the preferred embodiment of a kind of golf of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 and Fig. 2 show the detailed description of the invention of a kind of golf of the utility model: this golf comprises spherical shell 1, the diameter of shell 1 is 4.9mm, meet the regulation of standard golf-ball-size, the surface uniform of shell 1 is furnished with the triangle groove 4 of several equilateral circular triangles, the inside of shell 1 is provided with the ball core 3 of spheroidal, between ball core 3 and shell 1, be provided with intermediate layer 2, and intermediate layer 2 is netted.

In conjunction with Fig. 1 and Fig. 2, shell 1 is manufactured by carbamate, good springiness, and quality is hard, and the thickness of shell 1 is between 1.2-1.5mm. Intermediate layer 2 is manufactured by EP rubbers, good springiness. Ball core 3 is manufactured by ACM.

Triangle groove 4 has fully used aerodynamics, impels Transitional And Turbulent Flow to occur, and turbulent boundary layer is difficult for flow separation phenomenon occurs, thereby makes spheroid low-pressure area behind little, has reduced resistance, and the distance of golf ball flight is increased. Netted intermediate layer 2 can make to leave certain space in golf, has increased the elasticity of golf, can effectively increase the distance that impacts of golf.

Above is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
