Golf club head weight-adjusting structure
A golf club head weight-adjusting structure disposed perpendicularly at a rear position of the backside of a ball-striking plate comprises a containing body, an adjusting module and a cover panel. The containing body is extended from the rear of the backside of the ball-striking plate and forms a containing groove, and both sides of the containing groove include first and second slots. The adjusting module includes a weight member with its center screwed with the screw rod and pivotally coupled to the first and second slots. The screw rod includes a rotary element. A cover panel seals the containing groove of the containing body. With these simple components, the adjusting module increases the weight at the rear of the head to adjust and shift the center of gravity of the head backward and maintain the best central position when the adjusting module is installed to different golf club heads.

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 INVENTIONThere 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 INVENTIONThe 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.
BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting module 20 includes a weight member 21 contained in the containing body 10, and the screw rod 22 is extended to each rotary element 23 on both sides of the containing body 10. The weight member 21 is screwed with the screw rod 22, and a fixing element 24 such as a screw nut is designed for fixing the weight member 21 and the screw rod 22 or unscrewing the weight member 21 from the screw rod 22. In a preferred embodiment as shown in the figure, the center of the weight member 21 is screwed to both lateral positions of the outwardly extended screw rod 22 and contained in the containing groove 11 of the containing body 10. The adjusting module 20 installed in the containing body 10 is coupled parallel to the ball-striking plate 41, or the adjusting module 20a is coupled perpendicularly to the ball-striking plate 41a (as shown in
The rotary element 23 has a screw thread hole 230 disposed therein and screwed with the screw thread portion 220 and separately screwed onto the corresponding screw rod 22. Further, the rotary element 23 could have a design that could be held by a tool, and the design could be of various different geometric shapes. In this preferred embodiment as shown in the figure, the rotary element 23 is in a circular conical shape.
The fixing element 24 is a screw nut, and the quantity and relative installing positions of the fixing elements 24 can be set according to the actual needs of the weight-adjusting structure of the present invention, and the weight member 21 can be secured and screwed. In the preferred embodiment as shown in the figure, there are two fixing elements 24 disposed separately on both sides of the weight member 21 and screwed with the screw thread portion 220 of the screw rod 22, so as to achieve the effect of installing or uninstalling the weight member 21 to or from the containing groove 11 of the containing body 10.
The cover panel 30 is a member installed onto the containing groove 11 of the containing body 10, so that the cover panel 30 and the containing body 10 are connected to define a sealed status.
The first and second slots 12, 13 on both sides of the containing body 10 separately and axially receive the screw rod 22, and the rotary element 23 has an internal screw thread hole 230, such that the rotary element 23 can use its internal screw thread hole 230 to connect the screw rod 22, and the rotary element 23 can be rotated in the first and second slots 12, 13 of the containing body 10.
