Description
FIELD OF THE INVENTION

The present invention relates to a golf club head weight-adjusting structure, and more particularly to the design of a weight-adjusting structure that can be installed to various golf club heads for adjusting the center of gravity of the head and maintain its best central position to achieve the effect of striking a golf ball more accurately.

BACKGROUND OF THE INVENTION

There are different models of golf club head structures available in the market, and these golf club heads include driver heads, putt heads, and iron heads, and a golfer may not be able to stably control the ball striking direction of a swing, since the center of gravity of the golf club head is fixed and proximate to a ball striking surface plate which has a heavy weight based on the design of the golf club head.

However, the foregoing golf club head structure still has the following issues in the actual process of swinging a golf club to strike a golf ball:

1. The center of gravity for a swing is unstable. The structure of a traditional golf club head comes with a fixed center of gravity. If the center of gravity for a swing is found unstable, the balance of the swing will be lowered, and will thus adversely affect the stable control of striking a golf ball.

2. A poor control of striking a golf ball is resulted. Since the center of gravity of the head is fixed and proximate to the ball-striking plate, it is difficult to accurately control the ball striking direction when a strike is made by swinging the golf club head, and thus it affects the ball striking effect, and the control of striking a golf ball will not be as good.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a golf club head weight-adjusting structure in hope of using this design to provide a simpler weight-adjusting structure that can adjust the center of gravity of the head to maintain the best central position.

To achieve the foregoing objective of the present invention, a technical measure adopted by the invention provides a golf club head weight-adjusting structure, and the weight-adjusting structure disposed perpendicularly at a rear position of the backside of a ball-striking plate of various different models of golf club heads (such as driver heads, putt heads, and iron heads, etc) comprises a containing body, an adjusting module and a cover panel, wherein the containing body is extended outwardly from the rear end of the backside to form a containing groove therein, and both sides of the containing body have first and second slots, and the containing body is coupled and perpendicular to a rear end of the backside of a ball-striking plate of the head. The adjusting module includes a weight member, a screw rod screwed at the center of the weight member is pivotally coupled into the first and second slots, and the screw rod includes rotary elements separately disposed on both ends of the screw rod; and a cover panel is a member disposed on a containing portion of a base.

With the foregoing design of a golf club head weight-adjusting structure, the present invention can achieve the following effects:

1. A golf ball can be struck more accurately by adopting the invention. The weight-adjusting structure is perpendicularly disposed at a rear position of the backside of the ball-striking plate of different golf club heads, such that the screw rod disposed at a corresponding position of the adjusting module can be tuned to adjust the center of gravity of the head to shift backward, so as to increase the weight of the rear end of the head and achieve the effect of striking a golf ball more accurately.

2. The invention provides a simple structure. The weight-adjusting structure is comprised of simple components including a club head body, an adjusting module and a cover panel for adjusting the center of gravity of the head to shift backward and maintaining the center of gravity at the best central position, so as to achieve balanced and stable swings and ball striking direction and lower the manufacturing cost of the weight-adjusting structure.
