Description

golf club head

The invention relates to a golf club head, in particular to a golf club head made of different materials with high bonding strength.

A general golf club head includes a ball head body with a face opening on one side, and a striking panel connected to the side of the ball head body and closing the face opening. The ball head body and the beating panel are usually made of the same metal material and connected to each other by welding, but this design will cause the problem of single material and lack of variability and functionality, so the ball head also appears now. The body and the beating faceplate are made of dissimilar metals. This kind of golf club head combines the ball head body and the beating faceplate of different materials through brazing, but the joint strength of brazing is low. The thinner thickness of the faceplate will further reduce its impact resistance, and expensive soldering flux needs to be used in the brazing process, which increases the manufacturing cost of the golf club head.

Therefore, the object of the present invention is to provide a golf club head made of different materials that does not require brazing and has high bonding strength.

Therefore, the golf club head of the present invention includes a rear body component made of a metal material, and a front body component made of a metal material different from the rear body component. The rear body component includes a main body and a plurality of tenon parts protruding forward from the main body. The main body part has a ring end surface surrounding a rear opening, and the tenon parts protrude from the ring end surface. The front body component includes a striking panel part, and a surrounding wall part connected with the striking panel part and glued to the main body part. The surrounding wall part has a ring wall surface which surrounds a front opening and is glued to the end surface of the ring, and the ring wall surface forms a plurality of slots respectively for the tenon parts to be embedded in.

The effect of the present invention is that: the present invention increases the bonding strength through the tenon parts that are clamped in the slots, and cooperates with the ring end surface and the ring wall surface that are bonded to each other to improve the overall bonding strength. Bonding, so there is no need to use flux and can greatly reduce manufacturing costs. In addition, the integral design of the striking panel part and the surrounding wall part also increases the impact resistance of the striking panel part when hitting a ball.

Referring to Fig. 1 and Fig. 2, one embodiment of the golf club head of the present invention comprises a rear body assembly 1 made of stainless steel, a front body assembly 2 made of titanium alloy, and a bottom-up piercing Set the rear body assembly 1 and lock the bolt 3 on the front body assembly 2 .

Referring to FIG. 1 , FIG. 3 , and FIG. 4 , the rear body component 1 includes a main body portion 11 and a plurality of tenon portions 12 protruding from the main body portion 11 toward the front body component 2 . The main body 11 has a ring end surface 112 surrounding a rear opening 111 and protruding from the tenon parts 12 , and a through hole 113 is defined at the bottom of the main body 11 . In this embodiment, each tenon portion 12 is dovetail-shaped, and its length in the up-down direction is 2-20 mm, its width in the front-back direction is 1-6 mm, and its maximum outer diameter in the left-right direction is 1 to 10 mm (the outer diameter of the root is preferably 1 to 8 mm, and the outer diameter of the top is preferably 2 to 10 mm), and the width of the ring end surface 112 is 0.5 to 20 mm.

The front body assembly 2 includes a striking panel portion 21, a surrounding wall portion 22 connected to the periphery of the striking panel portion 21 and glued to the main body portion 11, and a wall portion 22 protruding backwards and passing through the rear wall portion 22. The opening 111 extends from the tab portion 23 inside the main body portion 11 . The surrounding wall portion 22 has a ring wall surface 222 surrounding a front opening 221 and is glued to the ring end surface 112 by gluing. The ring wall surface 222 is formed with a plurality of slots 223 respectively corresponding to the tenon portions 12 . In this embodiment, the embedding grooves 223 are in the shape of a dovetail groove, allowing the tenon parts 12 to be inserted from bottom to top and locked at the end. A locking hole 231 located above the through hole 113 and aligned with the through hole 113 is defined on the protruding piece 23 .

Referring to Fig. 2, Fig. 3, and Fig. 4, when the golf club head is assembled, the adhesive is first applied on the ring end surface 112 and the ring wall surface 222, and then the rear body assembly 1 and the front body assembly 2 close together, and at the same time put the tenon parts 12 into the slots 223 respectively, and make the rear body assembly 1 slightly slide up and down relative to the front body assembly 2, so that each tenon part 12 moves from bottom to top. Move up to the end of the corresponding slot 223 and be blocked, at this time the ring end surface 112 will align and touch the ring wall surface 222, and the rear body assembly 1 can be fixed to the front body assembly 2 through the adhesive On the other hand, the design of the tenon portions 12 and the slots 223 can further strengthen the bonding strength between the rear body component 1 and the front body component 2 . Finally, the bolt 3 passes through the through hole 113 of the main body 11 from bottom to top, and is locked on the lock hole 231 of the tab 23 . Combining the rear body component 1 and the front body component 2 through the bolt 3 can prevent the tenon portions 12 from sliding down along the slots 223 , and further enhance the overall bonding strength.

To sum up, the present invention can greatly improve the bonding strength of the golf club head by embedding the tenon portions 12 in the slots 223 , and cooperate with the locking of the bolt 3 and the bonding of the adhesive. Further improve binding force, so the purpose of the present invention can be really achieved.

But what is described above is only an embodiment of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by the patent of the present invention.
