Abstract

The utility model relates to a golf rod with a wind resistance eliminating rod body. In order to provide a golf rod which can eliminate the wind resistance when a golf is struck with the golf rod, increases golf rod intensity and fully exerts ball striking energy, the utility model is put forward and comprises a rod body, and a handle and a rod head which are respectively arranged at the top end and the bottom end of the rod body. The rod body is in the shape of an inverted truncated circular cone, and an outer surface is forms by inverted concave arc conical surfaces which are arranged at intervals along the circumference and the inverted convex arc conical surface. The cross section periphery of the rod body is composed of concave arc lines which are arranged at intervals and convex arc lines, and the position between the inverted concave arc conical surface and the inverted convex arc conical surface at the outer surface of the rod body is connected with the inverted conical surface. The inverted conical surface is formed by a plurality of continuous connected small inverted convex arc conical surfaces.

Description

Has the golf clubs of getting rid of the windage body of rod

The utility model belongs to the ground ball utensil, particularly a kind of golf clubs with eliminating windage body of rod.

As shown in Figure 1, general golf clubs is provided with the hollow round bar, is provided with handle in hollow round bar top, and its bottom then is articulated with the bar head.Therefore the round bar of this golf clubs of commonly using is level and smooth shape, when swinging square stance, as shown in Figure 2, forms certain windage in the round bar surface, retardation the action that swings, reduced the strength of batting relatively, even it can't give full play to the effect of batting.

The purpose of this utility model provides a kind of wind resistance that can get rid of the club square stance, increase club intensity, give full play to the golf clubs of getting rid of the windage body of rod that has of batting energy.

The utility model comprises the body of rod and is separately positioned on the handle and the bar head of body of rod top and bottom ends.The body of rod is the shape of falling the truncated cone, and the conical surface of falling the concave arc and the conical surface of falling the convex arc that its outer surface was arranged by the circle spacing constitute; Body of rod cross-sectional circumference is made up of spaced concave arc line and convex arc line; Be connected with inverted cone surface between the conical surface of falling the concave arc of body of rod outer surface and the conical surface of falling the convex arc; Inverted cone surface is made of the little conical surface of falling the convex arc of a plurality of continuous connections.

Wherein:

The body of rod is a ducted body, and its wall thickness is by thin gradually thick shape to the bottom from the top.

Spacing on the body of rod bottom transverse cross section between the two adjacent convex arc line summits is less than the spacing between the two adjacent convex arc line summits on the cross section of body of rod top; The height of point equates with the height of point at the bottom of the relative concave arc line in cross section epirelief camber line summit, body of rod top at the bottom of the relative concave arc line in epirelief camber line summit, body of rod bottom transverse cross section.

Because the utility model comprises the body of rod and is separately positioned on the handle and the bar head of body of rod top and bottom ends.The body of rod is the shape of falling the truncated cone, and the conical surface of falling the concave arc and the conical surface of falling the convex arc that its outer surface was arranged by the circle spacing constitute; Body of rod cross-sectional circumference is made up of spaced concave arc line and convex arc line; Be connected with inverted cone surface between the conical surface of falling the concave arc of body of rod outer surface and the conical surface of falling the convex arc; Inverted cone surface is made of the little conical surface of falling the convex arc of a plurality of continuous connections.Square stance swings, the conical surface of arranging by the body of rod outer surface circle spacing of falling the concave arc and the conical surface of falling the convex arc and the linking little conical surface of falling the convex arc by a plurality of continuous connections between the two constitute inverted cone surface and form turbulence structure, windage is got rid of by body of rod both sides, and quick in its back-end flowing through along body of rod both sides forms the thrust that acts on body of rod rear, give full play to body of rod batting energy, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises the body of rod 1 and is separately positioned on the handle 2 and the bar head 3 of the body of rod 1 top and bottom ends.The body of rod 1 is for being the shape of falling truncated cone ducted body, and its outer top to bottom without leave is descending gradually-reducing shape, and its wall thickness then is by thin gradually thick shape to the bottom from the top.The conical surface of falling the concave arc 111 and the conical surface of falling the convex arc 112 that the body of rod 1 outer surface 11 was arranged by the circle spacing constitute.The body of rod 1 cross section 12 (12 ') periphery is made up of spaced concave arc line 121 (121 ') and convex arc line 122 (122 ').Spacing between the body of rod 1 bottom transverse cross section 12 ' last two adjacent convex arc lines 122 ' summit is less than the spacing between two adjacent convex arc lines, 122 summits on the body of rod 1 top cross section 12.The height of 121 ' end of relative concave arc line, 12 ' epirelief camber line, 122 ' summit, the body of rod 1 bottom transverse cross section point equates with the height of 121 ends of relative concave arc line, the body of rod 1 top cross section 12 epirelief camber lines, 122 summits point.

Be connected with inverted cone surface 113 between the conical surface of falling the concave arc 111 that constitutes the body of rod 1 outer surface 11 and the conical surface of falling the convex arc 112.Inverted cone surface 113 is made of the little conical surface of falling the convex arc 1131 of a plurality of continuous connections.Make the body of rod 1 outer surface 11 form turbulence structure.With when swinging square stance, reduce windage with turbulence structure, and form the thrust that acts on the body of rod 1 rear, increase the batting dynamics.

As Fig. 1, Fig. 2, Fig. 9, shown in Figure 10, golf is when swinging, because the body of rod 1 is the state of brandishing fast, will form certain windage around it.The conical surface of falling the concave arc 111 that the utility model was arranged by the body of rod 11 circle spacings of 1 outer surface, the conical surface of falling the convex arc 112 and the linking little conical surface of falling the convex arc 1131 by a plurality of continuous connections between the two constitute inverted cone surface 113 and constitute turbulence structure, windage is got rid of by the body of rod 1 both sides, and quick in its back-end flowing through along body of rod both sides forms the thrust that acts on the body of rod 1 rear, give full play to the body of rod 1 and brandish effect, thereby encourage the body of rod 1 power increase striking force forward, make golf clubs be able to hit strength because of boosting power increase that wind resistance reduces and forms swings, give full play to body of rod batting energy, make batting more smooth and easy, stable.
