At present, the structure of habitual counter weight for golf club head, a kind of is to establish perforation on the club head coverboard, and establish the flange that extends internally in this perforation peritreme, and cooperation is established an internal diameter and is slightly larger than the balancing weight that this flange internal diameter, profile and perforation shape are complementary, to urge facility this balancing weight brute force is pressed into this perforation and flange inside again, this balancing weight is planted in flange and perforation, and make the balancing weight outer face concordant with perforation, and then form a counter weight construction, so that club head produces suitable counterweight effect; Yet the habitual counter weight for golf club head structure of this kind is bad because of structural design, can produce following shortcoming when implementing:

Embedded counter weight construction, fastness is poor: the fixed form of its balancing weight, only be that the mat balancing weight is designed to the big form of external diameter, the simple embedding in the flange, the fastness that its balancing weight combines with flange is relatively poor, especially club head is born great external force in the process of hitting, the situation that as easy as rolling off a log generation balancing weight gets loose.

Also have and plant habitual counter weight construction in addition, also be on the club head coverboard, to establish perforation, and establish the flange that extends internally in this perforation peritreme, and the balancing weight that cooperates a profile and perforation shape to be complementary, wherein, the fixing mode of the balancing weight of these habitual product and flange is: establish internal screw thread in flange inner wall, and the balancing weight side face is established external screw teeth, mat balancing weight and flange screw togather mutually and fix.Yet the habitual product of this kind are bad because of structural design, still can produce following shortcoming when implementing:

1, screw togather the formula counter weight construction, the counterweight fastness is relatively poor: it screws togather with balancing weight and flange, is brandishing batting when bearing big external force when its club head, and balancing weight still can anti-gomphiasis take off, so fastness is relatively poor.

2, screw togather the formula counter weight construction, the counterweight accuracy is relatively poor: it screws togather with thread, and particularly thread is under the impaired situation of machining deviation or tooth portion, and balancing weight can form deflected condition, and reduces the accuracy of counterweight.

3, screw togather the formula counter weight construction, aesthetic property is relatively poor: it screws togather mutually with thread, and these thread structures can make between balancing weight and the flange and form the gap, and this gap can influence the planarization of club head integral surface, and destroys the perfection sense that it is worked with great care.

The purpose of this utility model provides a kind of club head counter weight construction of taking into account fastness and effects such as counterweight accuracy and enhancement club head aesthetic property.

For achieving the above object, the utility model is taked following design: a kind of counter weight construction of golf driver head, on the club head coverboard, establish perforation, and in establishing, the perforation peritreme stretches flange, the balancing weight that proportion is bigger is filled in this perforation and the flange, flange is positioned at club head inside end inner edge and forms edge clipping, and outer rim projection formation connects edge; Be stretched on the card matching edge that the club head inside end is established projection and matched with above-mentioned edge clipping in balancing weight, edge clipping and card matching edge are fastened; Connect end in the flange tool and cover a cover plate and solid welding.

The utility model has adopted the said structure design, has following advantage:

1, wafer type structure, sound construction is good, the durability height: it forms edge clipping and connects edge in flange, and the card matching edge that closes in the balancing weight establishing, and cooperate and establish cover plate, make its balancing weight form outer form of wearing, and the inside and outside clipping of cover plate and edge clipping is lived the card matching edge of balancing weight, balancing weight is fixed really effectively, so its fastness is splendid, the durability height.

2, inside and outside wafer type structure, counterweight accuracy height: it is lived balancing weight with clipping inside and outside cover plate and the flange and fixes, and this balancing weight can not form deflected condition, so can significantly improve the accuracy of counterweight.

3, externally wearing type counter weight construction, promote the smooth aesthetic property of club head: as above-mentioned structural design, balancing weight is worn and the perforation of complete packing outside coverboard inside, can not formed the gap, after attrition process, just can form perfect club head, so can promote its aesthetic property.

The utility model is described in further detail below in conjunction with accompanying drawing.
