DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1-7, a golf club head of the present invention comprises a main shell 10, a ball striking face plate 20, two first counterweight installation portions 30, a second counterweight installation portion 40, and a plurality of screws B1.

The main shell 10 has a crown portion 11, a sole portion 19, a toe portion 12, a face plate connecting portion 13, two first counterweight installation portions 14, a second counterweight installation portion 15, three inner cylinder portions 16, three screw holes 17, and a groove 18. The main shell 10 is made of a light metal with a specific gravity of 1.7-4.7, such as magnesium alloy, aluminum alloy, titanium alloy, etc.

The toe portion 12 is integrally connected with the crown portion 11 and the sole portion 19. The face plate connecting portion 13 is connected with the front edges of the crown portion 11, the sole portion 19, and the toe portion 12. The two first counterweight installation portions 14 are provided at the sole portion 19 and arranged adjacent to the toe portion 12 and a heel portion 23, respectively. The second counterweight installation portion 15 is provided at the sole portion 19 and located between the first counterweight installation portions 14. The inner cylinder portions 16 are connected with the first and second counterweight installation portions 14, 15 and penetrated by the screw holes 17. The groove 18 is formed at the sole portion 19 and located between the first and second counterweight installation portions 14, 15 and the face plate connecting portion 13.

Further, the first counterweight installation portions 14 of the main shell 10 each have two lateral sides 141. The first counterweight mounting portions 14 are symmetrically arranged and extend obliquely toward the groove 18, so that the distance between the first counterweight installation portions 14 gradually decreases toward the groove 18.

The ball striking face plate 20 has a face portion 21 and a main shell connecting portion 22 attached to the face plate connecting portion 13 of the main shell 10. The ball striking face plate 20 is made of a heavy metal with a specific gravity of 7-18, such as steel alloy, copper alloy, tungsten-nickel alloy, etc. Preferably, the specific gravity of the ball striking face plate 20 is more than 1.5 times that of the main shell 10.

The first counterweight blocks 30 are installed in the first counterweight installation portions 14 of the main shell 10, respectively. The first counterweight blocks 30 each have a first fixing hole 31. The first fixing hole 31 is an elongated hole, such as an oblong countersunk hole. Two screws B1 are penetrated through the first fixing holes 31 and threaded with the screw holes 17 so as to fix the first counterweight blocks 30 to the main shell 10. As such, the toe portion 12 and the heel portion 23 can be equipped with the first counterweight blocks 30 made of different materials (carbon fiber, aluminum, stainless steel, tungsten-nickel alloy, etc.).

The first counterweight blocks 30 each have two lateral sides 32 corresponding to the two lateral sides 141 of the main shell 10 for facilitating assembly and adjustment. Additionally, one of the first counterweight blocks 30 is movable along a first moving line A1, and the other of the first counterweight blocks 30 is movable along a second moving line A2. The first moving line A1 and the second moving line A2 are intersected with each other near the groove 18, as shown in FIG. 5.

The second counterweight block 40 is installed in the second counterweight installation portion 15 of the main shell 10 so as to be located between the two first counterweight blocks 30. The second counterweight block 40 has a second fixing hole 41 that is a circular countersunk hole. One screw B1 is penetrated through the second fixing hole 41 of the second counterweight block 40 and threaded with the screw hole 17 of the main shell 10 so as to fix the second counterweight block 40 to the main shell 10. As such, the sole portion 19 can be equipped with the second counterweight block 40 made of different materials (carbon fiber, aluminum, stainless steel, tungsten-nickel alloy, etc.).

In accordance with the aforementioned structure, since the first fixing hole 31 of the first counterweight block 30 is an elongated hole, the first counterweight block 30 can be fixed at different positions on the main body shell 10 according to actual needs, as shown in FIGS. 8-10. In this way, different centers of gravity can be adjusted more conveniently and quickly. In addition, in this embodiment, the main body shell 10 only needs the screw hole 17 to obtain the adjustment function.

The golf club head is combined by two or more different materials, and the counterweight blocks with various specific gravity and materials are interchangeable to achieve the best function. It is powerful enough to meet any consumer's needs, and its center of gravity is closest to the hitting surface.

To sum up, the golf club head of the present invention can achieve the following effects through the aforesaid special structure: (1) It can increase the initial speed when hitting the ball. (2) It can increase the flight distance of the ball. (3) A high-quality hitting feel that is different from conventional golf club heads. (4) Pleasant hitting sound quality.

In addition, on one hand, the solder at the joints of the components with higher specific gravity is first processed in a vacuum furnace. Process description: sandblasting at the joints of the components→applying an agent to the joint→evenly sprinkling solder on the joint→processing in a vacuum furnace. On the other hand, the different components are combined with another solder with lower temperature. Process description: sandblasting the joints of the components processed once→combining the components→applying the second solder evenly on the joints→processing in a vacuum furnace.

From the above description, the present invention has the characteristics of high strength and high rebound.

In addition to the above embodiment, the present invention can also be implemented as follows:

For example, as shown in FIG. 11, the second counterweight block 40 can be omitted, i.e., the present invention does not need to install the second counterweight block 40 in different adjustment states of the first counterweight blocks 30, and the purpose of the present invention can also be achieved, which is not shown in the figure.

Alternatively, the first moving line A1 and the second moving line A2 may be parallel in the front-to-back direction, parallel to the left-right direction, or overlapped in the left-right direction. The purpose of the present invention can also be achieved.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
