Description

Hollow golf club head with metal sheet combination

The utility model relates to a counterweight structure of a hollow golf club head combined with metal sheets, in particular to a structure for setting a counterweight at the tail end of a hollow golf club head combined with metal sheets.

Existing golf club head structure at present has a kind of form that is combined and welded into hollow shell shape by several metal sheets, and this kind of club head forms hollow shell shape with metal sheet welding, can make it increase In the case of the volume of the club head, it will not increase its weight, but can still maintain the required weight principle; at present, it is more common to use several titanium alloy plates of appropriate shape to pre-puncher the bowl-shaped bottom with a mold shape, upper cover shape, striking surface, or the striking surface and the bottom are integrally formed, or the upper cover and the striking surface are integrally formed, then the bottom and the upper cover are covered, and it is welded into a hollow shell-shaped ball head, After surface processing, a complete club head is formed; for this kind of hollow ball head, in order to facilitate the adjustment of its center of gravity to the required position, a counterweight with a larger mass must be added on the ball head. The setting of the counterweight makes the center of gravity of the entire ball head meet the needs of the user; however, the current method of setting the center of gravity of this type of hollow ball head is generally just to plant the counterweight at the bottom, and this kind of ball head has not yet been seen. Combining hollow club heads with metal sheets has a counterweight added to the tail end of the club head, but because the counterweight is added at the bottom, it cannot achieve a greater effect if it can be adjusted (among them, the so-called center of gravity Depth refers to the distance from the edge line of the face to the center of gravity), and the center of gravity angle refers to the angle of inclination between the straight line of the center of gravity and the edge wire of the face when the center line of the club is in a horizontal free state, especially the depth of the center of gravity and the angle of the center of gravity There is an important demand for long-swing swings, because the depth of the center of gravity has the greatest impact on the performance of the ball head or whether it can effectively grasp the ball. The deeper the center of gravity, the larger the angle of the center of gravity, and the greater the return force of the ball head. As far as it is easy to grasp, for beginners or those with poor golf skills who use long golf swings, a head with a deeper center of gravity and a larger center of gravity angle is more suitable, especially among the current population of golfers, there are hundreds of golf balls. More than 80% of them belong to those with poor golf skills. Therefore, there is a certain market demand for the design of strengthening the depth of the center of gravity of the ball head. The need for improvement.

The purpose of the utility model is to provide a metal plate combined hollow golf club head capable of adjusting the depth of the center of gravity and meeting the counterweight structure required by long-swingers.

In order to achieve the above object, the utility model takes the following design scheme:

A metal plate combined hollow golf club head, which is mainly composed of an upper cover and a bowl-shaped bottom that are welded to each other to form a hollow club head. Connect the cue; it is characterized in that: the upper cover and the bottom are respectively cut at the tail end of the end of the striking surface to form the main missing edge and the auxiliary missing edge, and a positioning piece with the same material as the upper cover and the bottom is provided in addition, And a counterweight with a large mass, the periphery of the positioning piece just matches the outline surrounded by the main and auxiliary missing edges, and the profile of one side of the weight just matches the outline of the positioning piece, and the other side forms the club head The shape of the tail end is provided with lock holes on the positioning piece and the counterweight, and the lock bolts are fixed in the lock holes. In order to achieve that the hollow club head combined with metal sheets can also be provided with a counterweight at the tail end.

The bolts passing through the positioning piece and the counterweight can be locked in from the positioning piece first.

The bolts passing through the spacer and the counterweight can also be locked in from the counterweight first.

The bolt and the spacer are made of the same material, and the bolt and the spacer are welded into one body after the bolt is locked.

It cuts the corners of the upper cover and the bottom relative to the tail end of the striking surface to form the main edge and the auxiliary edge. In addition, a positioning piece and a high-quality counterweight are provided. The peripheral contour of the positioning piece is just right. It matches the outline of the main and auxiliary missing sides, and the profile of one side of the counterweight just matches the outline of the positioning piece, and the other side is the shape of the tail end of the club head, and there is a lock on the positioning piece and the counterweight. The hole is fixed through the locking bolt through the lock hole, so that the hollow club head combined with metal sheet can also be equipped with a counterweight at the tail end, and it can achieve both the firmness of the combination and the design flexibility of the depth of the center of gravity and the angle of the center of gravity. And it meets the needs of long-swingers.

Below in conjunction with accompanying drawing, the utility model is further described.
