Abstract

A golf club head structure includes a body portion, a hitting plate portion, and a club body combining portion. The body portion has a first junction surface forming a first hook angle therewith. The hitting plate portion has a hitting surface and a second junction surface with a buffer region spaced there-between. The second junction surface forms a second hook angle with the hitting plate portion, and butts against and attaches to the first junction surface on the same plane. The club body combining portion is provided for combining a club body. Therefore, a joint structure with a junction portion as a plane, capable of not being located on the surface of the club head and spaced by a buffer region with the hitting surface, is formed, which is applicable for solving the combination problem of the junction surface on the same plane that the casting is deformed.

Claims

1. A golf club head structure, comprising:

a body portion, having a first junction surface forming a first hook angle with a surface of the body portion;

a hitting plate portion, having a hitting surface and a second junction surface with a buffer region existing there-between, wherein the second junction surface forms a second hook angle with a surface of the hitting plate portion, so as to butt against and attach to the first junction surface on a plane; and

a club body combining portion, formed on the body portion or the hitting plate portion, for combining a club body,

wherein the first junction surface further has a stopper on an inner edge, so as to assist to press against and to position an outer edge of the second junction surface.

2. The golf club head structure as claimed in claim 1, wherein the first junction surface and the second junction surface are parallel to the hitting surface.

3. The golf club head structure as claimed in claim 1, wherein the body portion and the first junction surface are integrally formed into an extending structure.

4. The golf club head structure as claimed in claim 1, wherein the hitting plate portion and the second junction surface are integrally formed into an extending structure.

5. The golf club head structure as claimed in claim 1, wherein a junction structure of the first junction surface and the second junction surface is achieved through a brazing mode, a soldering mode, or a bonding mode.

6. The golf club head structure as claimed in claim 1, wherein the golf club head is a wood head, an iron head, or a putter.

7. A golf club head structure, comprising:

a body portion, having a first junction surface forming a first hook angle with a surface of the body portion;

a hitting plate portion, having a hitting surface and a second junction surface with a buffer region existing there-between, wherein the second junction surface forms a second hook angle with a surface of the hitting plate portion, so as to butt against and attach to the first junction surface on a plane; and

a club body combining portion, formed on the body portion or the hitting plate portion, for combining a club body,

wherein the second junction surface further has a stopper on an inner edge, so as to assist to press against and to position an outer edge of the first junction surface.

8. The golf club head structure as claimed in claim 7, wherein the first junction surface and the second junction surface are parallel to the hitting surface.

9. The golf club head structure as claimed in claim 7, wherein the body portion and the first junction surface are integrally formed into an extending structure.

10. The golf club head structure as claimed in claim 7, wherein the hitting plate portion and the second junction surface are integrally formed into an extending structure.

11. The golf club head structure as claimed in claim 7, wherein a junction structure of the first junction surface and the second junction surface is achieved through a brazing mode, a soldering mode, or a bonding mode.

12. The golf club head structure as claimed in claim 7, wherein the golf club head is a wood head, an iron head, or a putter.
