Description

Technical Field

[0001] The present invention relates to the technical field of golf putter heads, in particular to a golf putter head which is convenient for adjusting the center of gravity. Background Art

[0002] Golf is a globally popular sport, and in recent years, it has also grown rapidly in China, with an increasing number of people participating. The construction of golf courses and the emergence of golf training institutions have made this elegant sport increasingly accessible to the general public. Golf, combining physical activity, social connection, and natural experiences, possesses a unique charm, both as a competitive sport and as a leisure activity.

[0003] Currently, there are many ways to balance the weight of a golf putter head on the market. Many of these weighting methods embed a weight block on the side and fix it in the putter head, and then adjust the center of gravity by replacing the weight block. For example, the aforementioned golf putter head with adjustable center of gravity is disclosed in application publication number CN101732840A. Specifically, the putter head comprises a shaft for gripping and a head connected to the shaft. The head body comprises a striking face, a bottom face, and an open chamber formed by the bottom face and the striking face. A front threaded hole, a middle threaded hole, and a rear threaded hole are symmetrically arranged on the side of the open chamber of the head body. In one embodiment, a middle counterweight rod is screwed into the middle threaded hole, another embodiment comprises a front counterweight rod screwed into the front threaded hole and a rear counterweight rod screwed into the rear threaded hole, and yet another embodiment comprises a front counterweight rod screwed into the front threaded hole, a middle counterweight rod screwed into the middle threaded hole, and a rear counterweight rod screwed into the rear threaded hole, thereby forming three different weight levels of putter heads. The weight of the front counterweight rod is equal to that of the rear counterweight rod, but less than that of the middle counterweight rod. The front counterweight rod, the middle counterweight rod and the rear counterweight rod are made of stainless steel.

[0004] However, although the above-mentioned series of weight-adjustable golf putters can be used to form club heads of different weight levels, they still have some disadvantages. For example, since they are only provided with three horizontally arranged center of gravity adjustment holes, namely the front threaded hole, the middle threaded hole and the rear threaded hole, the three horizontally arranged center of gravity adjustment holes are not good enough for adjusting the center of gravity of the entire club head. For example, if a golfer wants to make multi-dimensional and fine adjustments to the club head, the three horizontally arranged center of gravity adjustment positions of the club head cannot meet such fine adjustments.

[0005] Therefore, there is a need to improve the existing technology. Summary of the Invention

[0006] In response to the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a golf putter head that is easy to adjust the center of gravity. A plurality of symmetrically distributed and obliquely arranged center of gravity adjustment holes are provided on the bottom surface of a putter head body, so that when the corresponding counterweight blocks are installed, the center of gravity of the putter head body can be finely adjusted according to the installation position and different weights of the counterweight blocks, thereby making it possible to use each center of gravity adjustment hole to achieve multi-dimensional center of gravity fine adjustment of the putter head body according to different adjustment methods.

[0007] In order to achieve the above object, the technical solution of the present invention is:

[0008] A golf putter head that is easy to adjust the center of gravity, comprising a putter head body; the front end surface of the putter head body is a ball hitting surface; at least two groups of adjustment holes are provided on the bottom surface of the putter head body; each group of adjustment holes includes two center of gravity adjustment holes, and the center of gravity adjustment holes in the two groups of adjustment holes are respectively two first center of gravity adjustment holes and two second center of gravity adjustment holes; the two first center of gravity adjustment holes are symmetrically distributed on both sides of the front end of the putter head body; the two first center of gravity adjustment holes are inclined relative to the ball hitting surface and their openings are respectively facing the outside of the putter head body; the two second center of gravity adjustment holes are symmetrically distributed On both sides of the rear end of the putter head body; the two second center of gravity adjustment holes are inclined relative to the hitting surface and the openings are respectively facing the outside of the putter head body; when the corresponding counterweight blocks are installed in each of the inclined center of gravity adjustment holes, the center of gravity of the putter head body can be fine-tuned according to the different installation positions and different weights of the counterweight blocks, so that the center of gravity of the putter head body can be slightly and gradually changed in different directions, and then the multi-dimensional center of gravity of the putter head body can be fine-tuned according to different adjustment methods; moreover, after fine-tuning the center of gravity according to the golfer's hitting habits, the straight-line hole rate of the shot can be improved.

[0009] The additional structure of the above technical solution also includes the following solutions:

[0010] Furthermore, the adjustment holes further comprise a third group of adjustment holes, wherein the third group of adjustment holes comprises two third center of gravity adjustment holes; the two third center of gravity adjustment holes are symmetrically distributed on both sides of the front end of the putter head body, and are located between the two first center of gravity adjustment holes and in front of the two second center of gravity adjustment holes; the two third center of gravity adjustment holes are inclined relative to the striking surface, and their openings face outward from the putter head body. This arrangement enables fine-grained adjustment of the putter head body from multiple angles.

[0011] Furthermore, the adjustment holes further comprise a fourth group, wherein the fourth group comprises two fourth center of gravity adjustment holes; the two fourth center of gravity adjustment holes are symmetrically distributed on either side of the front end of the putter head body, and are located between the two second center of gravity adjustment holes and the two third center of gravity adjustment holes; the two fourth center of gravity adjustment holes are inclined relative to the striking surface, and their openings face outward from the putter head body. This arrangement enables fine-tuning of the center of gravity on the putter head body from a wider range of angles.

[0012] Furthermore, the openings of the two first center of gravity adjustment holes are respectively oriented toward the left and right sides of the putter head body; the openings of the two second center of gravity adjustment holes are respectively oriented toward the rear end of the putter head body; the openings of the two third center of gravity adjustment holes and the two fourth center of gravity adjustment holes are respectively oriented toward the rear end of the putter head body. This arrangement enables various designs of the directions of the center of gravity adjustment holes to be formed.

[0013] Furthermore, the left and right sides of the front end of the bottom surface of the putter head body are respectively a first inclined surface that is inclined upward from the inside to the outside, the two first center of gravity adjustment holes are respectively located on the two first inclined surfaces, and the openings of the first center of gravity adjustment holes are flush with the first inclined surfaces; the rear end of the bottom surface of the putter head body is a second inclined surface that is inclined upward from the front to the back; the two second center of gravity adjustment holes are respectively located on the second inclined surface, and the openings of the second center of gravity adjustment holes are flush with the second inclined surface; the middle position of the front end of the bottom surface of the putter head body is a third inclined surface that is inclined upward from the front to the back, the two first inclined surfaces are respectively connected to the left and right sides of the third inclined surface, and the second inclined surface is connected to the rear side of the third inclined surface; the two third center of gravity adjustment holes and the two fourth center of gravity adjustment holes are respectively located on the third inclined surface, and the openings of the third center of gravity adjustment holes and the fourth center of gravity adjustment holes are respectively flush with the third inclined surface. The design of the above-mentioned inclined surfaces can effectively reduce the contact area between the putter head body and the turf, reduce friction, etc., and improve stability when hitting the ball.

[0014] Furthermore, the inclination of the first inclined surface is greater than the inclination of the second inclined surface and greater than the inclination of the third inclined surface. The above arrangement enables the putter head body to better hit the ball.

[0015] Furthermore, when the hitting surface is a vertical plane relative to the horizontal plane, the angle between the central axis of the first center of gravity adjustment hole and the hitting surface is 10°, the angle between the central axis of the second center of gravity adjustment hole and the hitting surface is 7°, the angle between the central axis of the third center of gravity adjustment hole and the hitting surface is 3°, and the angle between the central axis of the fourth center of gravity adjustment hole and the hitting surface is also 3°.

[0016] Furthermore, a ball-holding hole is provided at the rear end of the putter head body, which passes through the upper and lower ends of the putter head body, so that the ball can be picked up by using the ball-holding hole.

[0017] Furthermore, the upper and lower ends of the ball-holding hole are respectively of a structure that is wide outside and narrow inside, thereby making the ball-picking operation more convenient.

[0018] Furthermore, a grip installation hole with an opening toward the left or right side is provided on the top surface of the putter head body, thereby facilitating the installation of the grip.

[0019] The beneficial effects of the present invention are:

[0020] (1) The present invention utilizes the inclined center-of-gravity adjustment holes to coordinate with the installation of corresponding counterweights during use, thereby gradually shifting the center of gravity of the putter head body according to the installation position and weight of the counterweights, thereby achieving micro-adjustment of the center of gravity. This allows the center of gravity of the putter head body to be more subtly and gradually changed in different directions, resulting in different effects on the center of gravity of the putter head body at different positions. Therefore, after the above steps, the center of gravity adjustment holes can be used to achieve multi-dimensional micro-adjustment of the center of gravity of the putter head body according to different adjustment methods. Moreover, after micro-adjustment of the center of gravity according to the golfer's hitting habits, the straight-line hole rate of the shot can be improved.

DETAILED DESCRIPTION

[0033] The invention will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the invention.

[0034] like Figures 1-9 As shown, a golf putter head that is easy to adjust the center of gravity includes a putter head body 5. In addition, the front end surface of the putter head body 5 is a hitting surface 51. During use, the golfer can use the hitting surface 51 to hit the golf ball, thereby allowing the golf ball to enter the hole along the route.

[0035] Specifically, in order to facilitate fine adjustment of the center of gravity of the putter head body 5 , at least two groups of adjustment holes are provided on the bottom surface of the putter head body 5 .

[0036] Regarding the specific arrangement of the above-mentioned adjustment holes, as a preferred embodiment, each group of adjustment holes includes two center of gravity adjustment holes. The specific arrangement of these center of gravity adjustment holes is described in detail below:

[0037] First, in this embodiment, in order to achieve multi-dimensional center of gravity adjustment of the putter head body 5, the center of gravity adjustment holes in the two groups of adjustment holes are respectively two first center of gravity adjustment holes 1 and two second center of gravity adjustment holes 2. With respect to the above-mentioned two first center of gravity adjustment holes 1 and two second center of gravity adjustment holes 2, the two first center of gravity adjustment holes 1 are symmetrically distributed on both sides of the front end of the putter head body 5, and the two first center of gravity adjustment holes 1 are both inclined relative to the ball hitting surface 51 and the openings are respectively facing the outside of the putter head body 5; the two second center of gravity adjustment holes 2 are symmetrically distributed on both sides of the rear end of the putter head body 5, and the two second center of gravity adjustment holes 2 are also inclined relative to the ball hitting surface 51 and the openings are respectively facing the outside of the putter head body 5.

[0038] Therefore, during use, the present invention utilizes the inclined center of gravity adjustment holes to cooperate with the installation of corresponding counterweights, thereby gradually shifting the center of gravity of the putter head body 5 according to the installation position and different weights of the counterweights, thereby achieving micro-adjustment of the center of gravity, thereby gradually and subtly changing the center of gravity of the putter head body 5 in different directions, and having different effects on the center of gravity of the putter head body 5 at different positions. Therefore, after the above steps, the center of gravity of the putter head body 5 can be micro-adjusted in multiple dimensions according to different adjustment methods using the center of gravity adjustment holes; and after micro-adjusting the center of gravity according to the golfer's hitting habits, the straight hole rate of the shot can be improved.

[0039] The effects of using the putter head body 5 of the present invention will be explained in more detail below: Installing the counterweight in the forward first center of gravity adjustment hole 1 or the rearward second center of gravity adjustment hole 2 allows for forward or rearward center of gravity adjustment, respectively. A forward center of gravity (closer to the striking surface 51) generally makes the putter head body 5 feel lighter and more responsive when hitting a ball, while a rearward center of gravity (closer to the rear end) increases the moment of inertia of the putter head body 5, making the putter head body 5 more stable and reducing torsion when hitting a ball, thereby providing greater stability. The design of these center of gravity adjustment holes at different angles allows for more subtle and multi-directional adjustments to suit different golfers' stroke styles and needs. This flexibility helps golfers find the configuration of the putter head body 5 that best suits them, thereby improving their straight-line hole-in rate. Furthermore, the various center of gravity adjustment holes allow golfers to quickly adjust the weight distribution of the putter head body 5 based on different course and green conditions. For example, on faster greens, a golfer may prefer a more stable putter head body 5 with greater inertia, while on slower greens, a golfer may prefer a more flexible and responsive putter head body 5. This design allows for better dynamic adjustment. The varying weights and center of gravity also result in different sounds when the putter head body 5 is struck, which can, to some extent, affect the quality of the golfer's shot.

[0040] Second, in this embodiment, if Figure 2As shown, in order to achieve micro-adjustment of the center of gravity on the putter head body 5 from more angles, that is, multi-dimensional adjustment. There is also a third group of adjustment holes, and the center of gravity adjustment holes in the third group of adjustment holes are two third center of gravity adjustment holes 3; the two third center of gravity adjustment holes 3 are symmetrically distributed on both sides of the front end of the putter head body 5, and the two third center of gravity adjustment holes 3 are located between the two first center of gravity adjustment holes 1 and in front of the two second center of gravity adjustment holes 2. Moreover, the two third center of gravity adjustment holes 3 are inclined relative to the hitting surface 51 and the openings are respectively facing the outside of the putter head body 5. Therefore, the function of the above-mentioned third center of gravity adjustment hole 3 is also to make micro-adjustments to the center of gravity of the putter head body 5 in other directions, and the principle of use is basically the same as that of the first center of gravity adjustment hole 1 and the second center of gravity adjustment hole 2, and will not be described in detail here.

[0041] Third, in this embodiment, if Figure 2 As shown, in order to further adjust the center of gravity on the putter head body 5 from more angles, there is a fourth group of adjustment holes. The center of gravity adjustment holes in the fourth group of adjustment holes are two fourth center of gravity adjustment holes 4; the two fourth center of gravity adjustment holes 4 are symmetrically distributed on both sides of the front end of the putter head body 5, and the two fourth center of gravity adjustment holes 4 are located between the two second center of gravity adjustment holes 2 and the two third center of gravity adjustment holes. Specifically, the two fourth center of gravity adjustment holes 4 are basically located in the middle of the putter head body 5; the two fourth center of gravity adjustment holes 4 are inclined relative to the hitting surface 51 and their openings are respectively facing the outside of the putter head body 5. Similarly, the function of the third center of gravity adjustment hole 3 is also to fine-tune the center of gravity of the putter head body 5 in more directions, specifically to change the center of gravity at the middle position of the putter head body 5. Its operating principle is also basically the same as that of the first center of gravity adjustment hole 1, the second center of gravity adjustment hole 2, and the third center of gravity adjustment hole 3, and will not be described in detail here.

[0042] The following is a detailed description of the setting direction of each center of gravity adjustment hole, for example:

[0043] like Figure 3 and Figure 4 As shown, the openings of the two first center of gravity adjustment holes 1 are respectively facing the left and right sides of the putter head body 5, so that when the counterweight block is installed in the first center of gravity adjustment hole 1, it is inserted from the left or right side toward the middle of the front end. Correspondingly, as the counterweight block is inserted, the center of gravity will also be slightly offset from the left or right side to the middle of the front end following the counterweight block.

[0044] like Figure 3 and Figure 5As shown, the openings of the two second center of gravity adjustment holes 2 are respectively oriented toward the rear end of the putter head body 5. Furthermore, the openings of the two second center of gravity adjustment holes 2 can be rotated forward from the outside a certain distance, but not too much. In this way, the two second center of gravity adjustment holes 2 can be slightly rotated toward the front end of the putter head body 5. Similarly, when the counterweight is installed in the second center of gravity adjustment hole 2, it is inserted from the rear toward the middle. Correspondingly, as the counterweight is inserted, the center of gravity will gradually shift forward slightly following the counterweight.

[0045] At the same time, if Figure 3 and Figure 5 As shown, the openings of the two third center of gravity adjustment holes 3 and the openings of the two fourth center of gravity adjustment holes 4 are respectively facing the rear end direction of the push rod head body 5. Specifically, the openings of the two third center of gravity adjustment holes 3 and the openings of the two fourth center of gravity adjustment holes 4 can also be rotated forward a certain distance from the same side of the push rod head body 5. Similarly, the openings of the above-mentioned center of gravity adjustment holes should not be turned too much. In this way, the counterweight block can also cooperate well with the two third center adjustment holes 3 and the two fourth center of gravity adjustment holes 4 to achieve multi-dimensional center of gravity micro-adjustment. Similarly, when the counterweight block is installed in the third center of gravity adjustment hole 3 and / or the fourth center of gravity adjustment hole 4, it is basically inserted from the back to the front. Correspondingly, as the counterweight block is inserted, the center of gravity will gradually shift slightly following the counterweight block. In this embodiment, the openings of the two third center of gravity adjustment holes 3 and the two fourth center of gravity adjustment holes 4 are all in the same direction.

[0046] like Figure 2As shown, for other designs on the putter head body 5, the left and right sides of the front end of the bottom surface of the putter head body 5 are respectively the first inclined surfaces 6 inclined upward from the inside to the outside, the two first center of gravity adjustment holes 1 are respectively located on the two first inclined surfaces 6 and the opening of the first center of gravity adjustment hole 1 is flush with the first inclined surface 6, and the central axis of the first center of gravity adjustment hole 1 is substantially perpendicular to the first inclined surface 6; the rear end of the bottom surface of the putter head body 5 is the second inclined surface 7 inclined upward from the front to the back; the two second center of gravity adjustment holes 2 are respectively located on the second inclined surface 7 and the opening of the second center of gravity adjustment hole 2 is flush with the second inclined surface 7, and the second center of gravity adjustment hole 2 is substantially perpendicular to the first inclined surface 6. The central axis of the entire hole 2 is substantially perpendicular to the second inclined surface 7. A third inclined surface 8, sloping upward from front to back, is located in the middle of the front end of the bottom surface of the putter head body 5. Two first inclined surfaces 6 are connected to the left and right sides of the third inclined surface 8, respectively, and the second inclined surface 7 is connected to the rear side of the third inclined surface 8. The two third center of gravity adjustment holes 3 and the two fourth center of gravity adjustment holes 4 are respectively located on the third inclined surface 8, and the openings of the third center of gravity adjustment holes 3 and the openings of the fourth center of gravity adjustment holes 4 are respectively flush with the third inclined surface 8. The central axes of the third center of gravity adjustment holes 3 and the fourth center of gravity adjustment holes 4 are also substantially perpendicular to the third inclined surface 8. Because the various inclined surfaces on the bottom surface of the putter head body 5 are flush with the openings of the various center of gravity adjustment holes, the counterweight block can be more easily inserted into the corresponding center of gravity adjustment hole. In this embodiment, the inclination of the first inclined surface 6 is greater than the inclination of the second inclined surface 7, which is greater than the inclination of the third inclined surface 8.

[0047] Specifically, if Figure 2 As shown, since the corresponding first bevel 6, second bevel 7 and third bevel 8 are respectively provided on the bottom surface of the putter head body 5, the putter head body 5 can have many good use effects during the process of hitting the ball, for example: 1. The bevel design can effectively reduce the contact area between the putter head body 5 and the turf, reducing friction, making the putter head body 5 easier to slide without being slowed down by the turf, and this design can reduce the resistance during putting, especially when the turf is long or the green conditions are not ideal; 2. This design can reduce the bounce of the putter head body 5 when hitting the ball by optimizing the contact angle, so that the ball can roll more stably and the path is straighter, that is, the stability during hitting the ball is improved; 3. When the green is hard or soft, the design of the inclined bottom surface can provide good performance for the putter head body 5 to a certain extent, and the adaptability will also be stronger.

[0048] Combine Figure 3 In order to better understand the inclination angle of each center of gravity adjustment hole, the following is a further explanation: When the hitting surface 51 is a vertical surface relative to the horizontal plane, as shown in FIG. Figure 4 As shown, the angle between the central axis of the first center of gravity adjustment hole 1 (i.e., the left dotted line) and the hitting surface 51 (i.e., the right dotted line position) is 10°; Figure 5As shown in FIG. 1 , the angle between the central axis of the second center of gravity adjustment hole 2 (i.e., the right dotted line) and the hitting surface 51 (i.e., the left dotted line) is 7°; the angle between the central axis of the third center of gravity adjustment hole 3 (not shown) and the hitting surface 51 is 3°. Figure 6 As shown, the angle between the central axis of the fourth center of gravity adjustment hole 4 (i.e., the right dashed line) and the striking surface 51 (i.e., the left dashed line) is also 3°. Therefore, by utilizing the different angles between the central axis of each of the aforementioned center of gravity adjustment holes and the striking surface 51, the counterweight block can be installed in different center of gravity adjustment holes at different tilt angles, allowing for more subtle adjustments in various directions to accommodate different golfers' putting styles and needs. This flexibility helps golfers find the configuration of the putter head body 5 that best suits them. Furthermore, each of the aforementioned angles, determined through repeated testing by research and development personnel, is highly suitable for fine-tuning the center of gravity of the putter head body 5 and provides excellent results.

[0049] like Figure 1 and Figure 2 As shown, the rear end of the putter head body 5 is also provided with a ball-holding hole 9 that extends through the upper and lower ends of the putter head body 5. Specifically, the ball-holding hole 9 is installed at the position of the second inclined surface 7, that is, the ball-holding hole 9 is located at the rear end of the putter head body 5. The provision of the ball-holding hole 9 allows the putter head body 5 to use the ball-holding hole 9 to pick up a ball during use. For example, since the upper and lower ends of the ball-holding hole 9 are both open, when the lower end of the ball-holding hole 9 is aligned with the ball, the putter head body 5 can simply press down on the ball to lock it, eliminating the need to bend down to pick up the ball. Alternatively, if the ball is hanging in the grass, the upper end of the ball-holding hole 9 can be aligned with the ball, and then the putter head body 5 can be lifted up to lock the ball into the ball-holding hole 9, thereby completing the ball-holding action, which also eliminates the need to bend down to pick up the ball. Of course, the size of the ball-holding hole 9 is compatible with the size of the golf ball.

[0050] Preferably, Figure 1 and Figure 2 As shown, the upper and lower ends of the ball-locking hole 9 are respectively wide outside and narrow inside, so that the wide outside structure can make it easier for the ball to enter the ball-locking hole 9, and the middle position of the ball-locking hole 9 can be used to lock the ball, that is, to position the ball.

[0051] In addition, if Figure 1 As shown, a grip mounting hole 10 with an opening facing left or right is provided on the top surface of the putter head body 5 so as to install the grip in the corresponding direction, so that the grip can face left or right after installation.

[0052] Combine Figure 7 The following describes the operating principle of this embodiment to facilitate understanding of the present invention:

[0053] First, there are no corresponding counterweights 11 in each center of gravity adjustment hole. Then, when the golfer wants to adjust the center of gravity of different positions of the putter head body 5, he only needs to connect the corresponding counterweights 11 in the corresponding first center of gravity adjustment hole 1, second center of gravity adjustment hole 2, third center of gravity adjustment hole 3 and / or fourth center of gravity adjustment hole 4. Of course, the installation position, weight and even installation depth of the counterweights 11 will become factors that affect the center of gravity distribution. Therefore, this requires the golfer to make fine adjustments according to his own needs. The installation method of the counterweights 11 and the center of gravity adjustment holes can be connected by threaded connection, which will not be described in detail here.

[0054] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications of the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims of the present invention and equivalent technologies, the present invention is also intended to include these changes and modifications.
