Description

Angle adjustable golf club head

The present invention relates to a club head, in particular to a golf club head with an adjustable angle.

Referring to FIG. 1, the current golf club head capable of quickly changing clubs and adjusting the angle includes a club head body 11 surrounding and defining a shaft hole 111, and a head body 11 detachably inserted into the shaft hole 111 and the end is tapered. The rod sleeve 12, a screw 13 passing through the ball head body 11 and pressing against the inclined surface of the tapered portion of the rod sleeve 12, and a fixing that surrounds and fixes the rod sleeve 12 and is clamped in the rod hole 111 Ring 14. The axis line of the rod hole 111 and the axis line of the rod sleeve 12 are non-coaxial and sandwich a very small deflection angle with each other. The rod sleeve 12 is used to insert and fix a shaft 15. By detaching the screw 13 and disassembling the rod sleeve 12, the rod sleeve 12 and the shaft 15 can be replaced to achieve the function of quick rod change In addition, since the axis line of the rod sleeve 12 and the axis line of the rod hole 111 are non-coaxial and slightly skewed, the rod sleeve 12 can also be detached from the rod sleeve 12 relative to the ball The head body 11 rotates, and the rod sleeve 12 is inserted into the rod hole 111 again. At this time, the angle between the rod sleeve 12 and the ball head body 11 is changed, so that the user can hit according to himself The ball is used to adjust the angle between the shaft 15 and the ball head body 11, and the fixing ring 14 is used to fix the angle of the sleeve 12 after the adjustment is completed.

However, when adjusting the angle of the aforementioned conventional golf club head, the sleeve 12 and the head body 11 need to be relatively rotated, which will cause the shaft 15 fixed on the sleeve 12 to also be relative to the head body 11. Rotation, so that the logo on the shaft 15 or the sleeve 12 will deviate from the original position, resulting in the inability to align the ball head body 11 or destroy the original visual effect. In addition, if the top of the shaft 15 If the grip is connected, the aforementioned way of adjusting the angle will also deflect the direction of the grip, which will cause the user to grasp the grip unsatisfactorily and affect the feel of hitting the ball.

Therefore, the object of the present invention is to provide a golf club head that can adjust the angle without affecting the LOGO direction and handle direction on the shaft or grip.

Therefore, the adjustable-angle golf club head of the present invention includes a head body defining a shaft hole, an adjusting ring detachably placed in the shaft hole and surrounding a deflection hole, and an extension A rod sleeve in the shaft hole and partly clamped in the deflection hole, and a ball head body penetrated from bottom to top and locked on the shaft sleeve to fix the shaft sleeve on the ball The fixing part on the head body.

The ball head body includes an inner wall surface surrounding and delimiting the rod hole, and the inner wall surface forms a positioning groove connected with the rod hole and extending upward. The deflection hole obliquely extends from the top surface to the bottom surface and is arranged non-axially with the rod hole, and the axis line of the deflection hole and the axis line of the rod hole sandwich an angle. The rod sleeve includes a positioning portion protruding outward in its radial direction and detachably clamped in the positioning groove. The positioning portion restricts the rod sleeve from rotating relative to the ball head body. When the adjusting ring is opposite to When the shaft sleeve rotates, the angle between the shaft sleeve and the ball head body changes accordingly.

The effect of the present invention is: through the design of the oblique hole extending obliquely and eccentrically with the shaft hole, the user can change the position between the shaft sleeve and the ball head body by rotating the adjusting ring relative to the shaft sleeve. Because of the clamping angle, the rod sleeve does not need to rotate relative to the ball head body. The design of the positioning portion being locked to the positioning groove can also ensure that the rod sleeve and the ball head body will not rotate relative to each other. This can keep the shaft and grip in place, avoiding the displacement of the logo on the shaft or the grip or changing the direction of the handle.

2 and 3, an embodiment of the adjustable angle golf club head 2 of the present invention includes a ball head body 21, an adjusting ring 22 detachably disposed in the ball head body 21, and a plug A rod sleeve 23 arranged in the ball head body 21 and partially clamped to the adjusting ring 22, a fixing member 24 that penetrates the ball head body 21 from bottom to top and whose end is locked on the rod sleeve 23, A positioning ring 25 set on the rod sleeve 23 and clamping the adjusting ring 22, a sealing ring 26 set on the rod sleeve 23 and located in the adjusting ring 22, and two pierced by the fixing member 24置的垫27。 Set the gasket 27. The ball head body 21 includes an inner wall surface 212 surrounding and defining a rod hole 211, and the inner wall surface 212 forms a positioning groove 213 communicating with the rod hole 211 and extending upward along the extending direction of the rod hole 211.

Referring to FIGS. 2, 4, and 5, the adjusting ring 22 is detachably placed in the rod hole 211, and surrounds and defines a deflection hole 221 extending from its top surface to the bottom surface. The deflection hole 221 The axis E of the rod hole 211 and the axis F of the rod hole 211 are not on the same line (that is, they are set on different axes), and an angle G is sandwiched between the two. The rod sleeve 23 includes an extension portion 231 inserted into the rod hole 211, a positioning portion 232 protrudingly provided on the outer circumference of the extension portion 231 and detachably clamped in the positioning groove 213, and A receiving portion 233 connected to the top of the extension portion 231 outside the rod hole 211 and suitable for connecting to a shaft 3. The extension 231 has an indexing feature 234 with a polygonal cross section and inserted in the deflection hole 221. In this embodiment, the cross section of the indexing feature 234 is octagonal, but it can also be other types of polygons, and it is not limited thereto. The extension 231 also forms a ring groove 236 and a groove 237 located below the ring groove 236 and surrounding the indexing feature 234.

The fixing member 24 is a screw, which fixes the rod sleeve 23 on the ball head body 21. The positioning ring 25 is elastic and is sleeved in the groove 237 so as to be located between the indexing feature 234 and the adjustment ring 22 in the radial direction. The sealing ring 26 is sleeved in the ring groove 236 so as to be located between the extending portion 231 and the adjusting ring 22 in the radial direction. In this embodiment, the positioning ring 25 and the sealing ring 26 are O-rings made of rubber, but not limited to this. One of the spacers 27 between the fixing member 24 and the ball head body 21 is made of metal material, and the other is between the ball head body 21 and the shaft sleeve 23. 27 is made of rubber.

Referring to Figures 2, 4, and 6, in this embodiment, the rod sleeve 23 together with the positioning ring 25, the sealing ring 26, and the adjusting ring 22 can be detached from the ball head after the fixing member 24 is detached. After replacing the main body 21 with a set of rod sleeves 23 connecting different shafts 3 (the positioning ring 25, the sealing ring 26, and the adjusting ring 22 can be used or another set), the effect of quick rod change is achieved. On the other hand, when the angle needs to be adjusted, the fixing member 24 is also detached first, and then the rod sleeve 23 together with the positioning ring 25, the sealing ring 26, and the adjusting ring 22 are detached from the ball head body. 21. Then the adjustment ring 22 is rotated relative to the indexing feature 234. Since the cross section of the indexing feature 234 is octagonal, eight can be generated when the adjustment ring 22 is rotated relative to the rod sleeve 23 Quickly adjust the angle position. After the adjustment ring 22 and the rod sleeve 23 are relatively rotated, the components are assembled in the previous disassembly sequence. At this time, the angle between the rod sleeve 23 and the ball head body 21 H (that is, the axis E of the deflection hole 221 and the axis F of the rod hole 211 sandwich another angle H) will be changed due to the relative rotation of the rod sleeve 23 and the adjustment ring 22. It should be particularly noted that when the rod sleeve 23 is reinserted into the rod hole 211, the positioning portion 232 will be clamped in the positioning groove 213 again, so that the rod sleeve 23 and the ball head body 21 are as if not yet Before adjusting the angle, the alignment is maintained without relative rotation, so the shaft 3 and the ball head body 21 will not be offset. This way, the shaft 3 or sleeve 23 can be avoided while adjusting the angle. LOGO deviation or change of grip direction. The appearance of the indexing feature 234 allows the user to position faster and more accurately when adjusting the angle, which improves the convenience and intuition of adjustment.

It should be noted that although the shape of the indexing feature 234 provides eight different directions of angle positions for the sleeve 23 to position, so that the shaft 3 and the ball head body 21 can quickly and accurately be positioned in eight positions. Adjust between different angles, but the user does not only have these eight relative positions to choose from. In other words, when the user rotates the adjustment ring 22, the position does not follow the angle position of the indexing feature 234, so that The shaft 3 and the ball head body 21 generate angles other than the eight positions. Of course, the cross section of the indexing feature 234 can also be of other shapes, thereby generating different numbers of quickly adjusted angle positions.

To sum up, in addition to the quick change of rods, the present invention will not make the shaft 3 and the ball head body 21 rotate relative to each other when adjusting the angle, which can avoid the misalignment or grip of the LOGO on the shaft 3 or the grip. The change of the handle can also allow the user to quickly and accurately adjust the angle between the shaft 3 and the ball head body 21 according to the eight angle positions, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
