Description

Golf iron head structure for adjusting center of gravity and method for adjusting center of gravity

technical field

The invention relates to the field of golf equipment, in particular to a structure of a golf iron club head and a use method thereof.

Background technique

In addition to the technical characteristics of golf clubs, the rebound ability and shock absorption ability of the club must also be considered based on personal hitting habits, physical fitness and preference. That is to say, in addition to relying on hitting skills, choose A well-designed counterweight and a golf iron head that suits your personal feel will have a great impact on the effect of hitting. Most of the current golf iron ball head counterweight methods are to embed the counterweight on the bottom surface or the side, and fix it in the iron club body. However, since the center of gravity of each golf iron club head is different, if the center of gravity cannot be adjusted, it will affect the sense of movement balance of the hitting iron club head and the flight state after hitting the ball. The method of adjusting the center of gravity is generally limited to adding a small counterweight unit on the outside, or disassembling and replacing the internal counterweight unit. For the small counterweight unit added externally, because it is exposed outside, it is easily affected by wear or protruding shape, and the accuracy of hitting the ball is affected by the change of airflow during swing. Simultaneously, general golf iron club heads are also difficult to clean in certain positions, which affects appearance and performance.

Contents of the invention

The present invention aims at the deficiencies in the above-mentioned background, and provides a golf iron ball head structure that can adjust the center of gravity. The method of adjusting the center of gravity of the golf iron head to make the hitting more stable and more suitable.

Its realized technical scheme is as follows:

The golf iron head structure for adjusting the center of gravity includes an iron head body and a counterweight. The surrounding edges of the iron head body protrude to form a space corresponding to the size of the head. The iron head body and the counterweight There is a detachable fastener between them, and the fastener and the counterweight are fixed on the lower half of the back of the hitting surface of the iron ball body; one edge of the counterweight is attached to the lower edge of the back of the iron ball head combined, there is an accommodation space between the weight block and the middle position on the back of the hitting surface of the iron ball head body.

Further, the said fasteners are fixed at least two places, and the fasteners here are screws with the same or different specifications, or snap-fit parts with the same or different specifications, and the specifications include shape, size, material and weight.

Further, the height of the back of the hitting face of the iron club body gradually decreases from the center to the edge, and the inner edge of the hitting face is a circle of closed grooves.

Furthermore, there is a low-temperature soldering paste that closely adheres the iron ball body and the counterweight between the iron ball body and the counterweight.

A method for adjusting the center of gravity of a golf iron head. Two combinable iron head bodies and counterweights are provided. The surrounding edges of the back of the iron head protrude to form an accommodating space. There are at least two fasteners between them for tight fixing, wherein the fasteners can use detachable components such as screws or snap-fit parts; The lower half of the back of the face can be replaced with fasteners or counterweights of different specifications according to the need for fine-tuning of the hitting force or the hitting center of gravity.

Further, a low-temperature soldering paste that closely adheres the iron ball body and the weight can also be glued between the iron ball body and the weight, without replacing the weight.

Furthermore, the counterweight is set to be fixed on the lower end edge of the back of the hitting surface of the iron club body, so that the two fit together, leaving a space between the upper end of the counterweight and the middle position of the iron club body. the accommodation space described above.

Further, the height of the back of the hitting surface of the iron club body gradually decreases from the center to the edge, and a circle of closed grooves is provided on the inner edge.

The beneficial effects of the present invention are: using the combinable iron ball body and counterweight, different counterweights can be replaced according to the hitting force, or use low-temperature soldering paste for firm bonding; The center of gravity is also important. The fasteners use screws or snap-fit parts, which can be replaced as needed, that is, to achieve fine-tuning of the center of gravity, so as to obtain the optimal combination of iron club head selection during hitting, eliminating the need to carry multiple golf balls The cumbersome needs of the club can increase the ability to control the direction, height, and distance of the iron head; moreover, a groove is set on the inner edge of the back of the iron head body, and the weight is only connected to the iron ball. The lower edge of the head body fits together, and the upper part has accommodating space, which makes it more convenient to clean inside, and the ability to control the iron ball head can be increased by 10%~35%; the middle position of the back of the iron head body hitting surface It is higher than the edge, which can make the ball hit farther when hitting, and can also guide the liquid into the groove for easy drainage when cleaning.
