Description

Golf club head

The invention relates to a golf club head, in particular to a golf club head with a weight.

Golf club heads are often provided with weights on the head to change the center of gravity of the head. In order to change the weight of the weights according to different situations, many weights are designed to be detachable. Referring to FIG. 1, taking the golf club head 1 of FIG. 1 as an example, the ball head 11 is provided with a lock hole 111, and the weight member 12 is designed as a bolt structure, and is locked into the head from bottom to top 11Bottom keyhole 111. However, when the golf club head 1 needs to adjust the weight and the weight 12 needs to be replaced, the user needs to loosen the weight 12 from the lock hole 111 with a screwdriver or the like until the weight After the member 12 completely withdraws from the lock hole 111 along the threaded stroke of the lock hole 111, the weight member 12 can be removed. This will take a lot of time and is likely to cause user impatience, especially during competitions or exercises. It is easier to increase user anxiety. If the thread stroke of the lock hole 111 is reduced, it will cause the problem of insufficient fixing strength of the counterweight 12 and easy loosening. Therefore, there is still room for improvement in the traditional counterweight locking structure.

Therefore, the object of the present invention is to provide a golf club head that can save time for disassembling and replacing weights and greatly improve convenience.

Therefore, the golf club head of the present invention includes a ball head and a weight. The ball head includes a main shell recessed inwardly from the outer surface to form a set groove, a top cover connected to the main shell, a hitting panel connected between the main shell and the top cover, and a The main shell extends into the rib in the setting groove. The setting groove is located behind the hitting panel along a hitting direction.

The weight piece is located in the setting groove, and includes a weight block, a nut located above the rib, and a bottom-to-top through the weight block and the rib in order and screwed on the The screw on the nut. The rib forms a slot through which the weight of the weight member passes. When the screw is tightened, the screw and the nut fix the weight on the rib in a clamping manner. When the screw is loosened, the screw can be taken out along the slot at the same time, and the weight can be taken out from the setting slot.

The effect of the present invention is that, through the design of the ribs and the slot, the user only needs to loosen the screw when removing the weight, instead of completely removing the screw from the nut, which can save Replacement time and greatly improve convenience.

Referring to FIGS. 2, 3 and 4, an embodiment of the golf club head 2 of the present invention includes a ball head 3 and a weight member 4 detachably fixed to the ball head 3. The ball head 3 includes a main housing 31, a top cover 32 connected to the main housing 31, a ball striking panel 33 connected between the main housing 31 and the top cover 32, and a main housing 31 The rib 34 on the body 31 and two positioning protrusions 35 protruding from the rib 34 at intervals. The main housing 31, the top cover 32, and the ball striking panel 33 may be integrally formed, or may be of an assembled design. Of course, the two may be matched with each other, for example, the main housing 31 and the top cover 32 are integrally formed However, the ball striking panel 33 is fixed to the main housing 31 by welding or other methods, and is not limited to this. A hitting direction 5 is defined, which refers to the forward and backward extension direction when a general user hits the ball with the golf club head 2, which is substantially the same as the normal of the hitting panel 33. The main casing 31 is recessed inwardly from the outer surface to form a setting groove 311. The setting groove 311 is located behind the striking panel 33 along the striking direction 5 and is located at a position farthest from the striking panel 33 and adjacent to the main At the boundary edge 6 between the casing 31 and the top cover 32, the rib 34 extends from the main casing 31 in the hitting direction 5 into the setting groove 311, the rib 34 forms an opening backward and The opening 341 of the installation groove 311 is in the same direction. The positioning bumps 35 are located on both sides of the slot 341 and protrude upward to form a semi-spherical shape.

2, FIG. 3, and FIG. 5, the weight 4 is detachably installed in the setting groove 311, including a weight 41 corresponding to the shape of the setting groove 311, and a fin A nut 42 above 34, and a screw 43 that penetrates the weight 41 and the rib 34 in sequence from bottom to top and locks on the nut 42. Through the opening position of the setting groove 311, the weight member 4 can be located at a low height position away from the ball striking panel 33 and adjacent to the boundary edge 6, so that the invention can obtain the ball hitting characteristics of a low depth center of gravity and can have high rotation Moment of inertia (MOI), which increases the sweet spot and has a higher fault tolerance rate. The material of the weight 41 is one of metal injection molding (Metal Injection Molding, referred to as MIM) tungsten pellets, stainless steel, titanium alloy, aluminum alloy, or plastic injection parts, through different density materials can be The same volume (that is, in conformity with the appearance of the setting groove 311) makes weights 41 of different weights for replacement. The nut 42 is a rectangular nut, the shape of which is limited by the main housing 31 and cannot be rotated in the setting groove 311, so it can only be taken out or placed in the nut 42 along the direction 5 of hitting the ball. The nut 42 is formed with a screw hole 421 matched with the screw 43 and two limit holes 422 located on both sides of the screw hole 421 for the positioning protrusions 35 to protrude into. The positioning protrusions 35 are respectively embedded in the limiting holes 422, which can achieve the limiting effect of preventing the nut 42 from sliding or falling off relative to the rib 34, and can also be placed on the rib 34 in the nut 42 When going up, the positioning bumps 35 are slid into the limiting holes 422 through the semi-circular shapes of the positioning bumps 35, and then the nut 42 is positioned.

Since the nut 42 is limited by the main housing 31 as described above and cannot be rotated in the installation groove 311, the user does not need to worry about fixing the nut 42 when turning the screw 43 When the screw 43 is tightened, the screw 43 and the nut 42 fix the weight 41 to the rib 34 in a clamping manner, so that the weight 41 is installed in the setting groove 311. When the screw 43 is loosened, the screw 43 and the nut 42 no longer clamp the weight 41 and the rib 34, at this time the screw 43 can be taken out along the slot 341, and at the same time The weight 41 penetrated by the screw 43 and the nut 42 that has not completely disengaged from the screw 43 are taken out together, so that the weight 4 is taken out of the setting groove 311, and the user does not need to completely disengage the screw 43 from the screw The cap 42 only needs to be loosened moderately, and this design can greatly reduce the time for removing and replacing the weight 4.

In summary, in the present invention, when the weight member 4 is replaced, the screw 43 does not need to be completely detached from the nut 42, which can speed up the replacement and facilitate the rapid replacement of the weight member 4 made of different materials. Adjust the weight according to the demand. On the other hand, by arranging the weight 4 at the lowest height position on the edge of the head 3, the golf club head 2 can obtain the hitting characteristics of the deep and low center of gravity counterweight. The increase in the sweet area of hitting can increase the error tolerance and increase the MOI value, so it can really achieve the purpose of cost invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as This invention covers the patent.
