Description

technical field

[0001] The invention belongs to golf equipment parts, in particular to a golf club head with a material escape hole formed at the connecting part. Background technique

[0002] Such as figure 1 As shown, a conventional golf club head 1' is made of metal material, which includes a club head body 10', a ball striking face plate 11' for hitting a ball, a connecting portion 12' and a collar 13 for combining with the club '. The batting panel 11' and the collar 13' are connected by the connecting portion 12'.

[0003] Usually, when the golf club head 1' is manufactured in the industry, the large weight of the connection part 12' and the sleeve neck 13' is often ignored, so that the center of gravity 14' of the golf club head 1' is too close to the connection part 12' And deviate from the main hitting area of ​​the hitting panel 11', as a result, shorten the moment of inertia of the golf club head 1' and reduce the efficiency of the golf club head 1' in transfer...

Examples

Embodiment 1

[0026] Such as image 3 , Figure 4 As shown, the golf club head 1 in which the connection part of the present invention forms a material escape hole is made of metal or alloy material, and it includes a club head body 10, a ball hitting face plate 11 for hitting a ball, a connection part 12 and a connecting part 12 to combine with the ball. The sleeve neck 13 of rod.

[0027] The front of the club head body 10 is provided with a joint portion 101 for the ball striking panel 11 to be embedded, pressed, brazed, welded, screwed or integrally formed.

[0028] The connecting portion 12 is connected between the ball striking panel 11 and the sleeve neck 13 , and an escape hole 121 is formed as a through hole or a blind hole.

[0029] When the escape hole 121 is a blind hole, the opening of the escape hole 121 is opened on the front or back of the golf club head 1 . The weight of the upper and lower halves of the connecting portion 12 can be uniformly reduced by the escape hole 1...
