Golf club head weight-adjusting structure

Abstract

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.

1 . A golf club head weight-adjusting structure, disposed perpendicular to a rear position on the backside of a ball-striking plate of different golf club heads and comprising: 
 a containing body, coupled to and disposed perpendicular to a rear end on the backside of different golf club heads, and having a containing groove and corresponding first and second slots disposed on both sides of said containing body;    an adjusting module, including a weight member contained in said containing body, a rotary element disposed separately on both sides of a screw rod, and said weight member being screwed to said screw rod, and said weight member having at least one fixing element disposed on both sides of said weight member; and    a cover panel, being detachably installed to a member on said containing groove of said containing body.    
   
   
       2 . The golf club head weight-adjusting structure of  claim 1 , wherein said screw rod has a screw thread portion and pivotally coupled to said corresponding first and second slots on both sides of said containing body.  
   
   
       3 . The golf club head weight-adjusting structure of  claim 2 , wherein said rotary element includes an internal screw thread hole therein and screwed with said screw thread portion of said screw rod.  
   
   
       4 . The golf club head weight-adjusting structure of  claim 1 , wherein said adjusting module is perpendicularly screwed to a rear position of the backside of a ball-striking plate.  
   
   
       5 . The golf club head weight-adjusting structure of  claim 1 , wherein said weight-adjusting structure is disposed parallel to a containing space at a rear end of the backside of said ball-striking plate of different golf club heads, and a corresponding containing hole is formed separately on both sides of said containing space.  
   
   
       6 . The golf club head weight-adjusting structure of  claim 5 , wherein said weight-adjusting structure comprises an adjusting module and a cover panel, and said adjusting module comprises a weight member contained in said containing space, and a screw rod extended into said fixing element of said corresponding containing hole; and said cover panel being a member installed into said containing space at a rear end of the backside of said ball-striking plate.  
   
   
       7 . The golf club head weight-adjusting structure of  claim 6 , wherein said weight member at its center forms a screw hole for coupling said screw rod.  
   
   
       8 . The golf club head weight-adjusting structure of  claim 6 , wherein said fixing element includes an internal screw thread hole corresponding to said screw rod for passing said screw rod through said internal screw thread hole and being secured with said fixing element.
