Description

Technical Field

[0001] This utility model relates to the field of golf club technology, and in particular to an adjustable-length golf club. Background Technology

[0002] With the increasing demand for family leisure and entertainment, backyard golf toys have gradually become a popular choice for parent-child interaction and family recreation. In order to meet the different usage needs of children and adults, while taking into account the convenience of storage and transportation, adjustable length golf clubs have become an important design direction for such products. These clubs need to meet the requirements of flexible length adjustment, while also taking into account the safety of use, ease of operation, and grip comfort of different people, so as to adapt to the diverse usage needs in family scenarios.

[0003] In the existing technology, adjustable length golf clubs mostly adopt a sleeve-type telescopic structure. The principle is to achieve length adjustment by sliding the inner and outer nested shafts against each other. They are usually fixed by the cooperation of elastic buckles and positioning holes at the shaft connection. In addition, in order to facilitate use by children, the shaft material is usually made of aluminum alloy.

[0004] However, existing technologies struggle to balance the relationship between lightweight materials and connection strength. When lightweight materials are used, adults may apply excessive force or mishandle the connection during use, which can easily lead to breakage. If the material is changed or the wall thickness is increased to improve connection strength, the overall weight will increase, which is not conducive to children's use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable length golf club, which aims to improve the problem that existing technology makes it difficult to balance the relationship between lightweight materials and connection strength. Lightweight materials are prone to breakage during adult use, and if the material is changed or the tube wall is thickened to enhance the connection strength, the overall weight of the product will increase, which is not conducive to children's use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-length golf club, designed to meet the diverse usage needs of people of different heights, comprising: The pole has a first body, an inner wall of which is provided with a second body, and an inner wall of which is provided with a third body. The three bodies work together to accommodate the length adjustment needs of users of different heights. Shim 1 and shim 2, wherein shim 1 is symmetrically disposed between the inner wall of shaft 1 and the outer wall of shaft 2, and shim 2 is symmetrically disposed between the inner wall of shaft 2 and the outer wall of shaft 3, for reinforcing the connection between the two shafts and preventing relative rotation between the shafts; Anti-slip and shock-absorbing sleeve, fitted onto one end of the shaft, is used to provide anti-slip grip and absorb vibrations generated during impact; The clubhead, located at the bottom three ends of the shaft, is used to improve stability and control during the shot.

[0007] Furthermore, a locking hole is provided on the outer wall of the second rod body, and a locking block is fixedly connected to the inner wall of the first gasket, with the outer wall of the locking block being disposed on the inner wall of the locking hole.

[0008] Furthermore, the outer wall of the rod body three is provided with a second locking hole, and the inner wall of the gasket two is fixedly connected with a second locking block, and the outer wall of the second locking block is disposed on the inner wall of the second locking hole.

[0009] Furthermore, a threaded tube is provided at the bottom end of the rod body, and a nut is threadedly connected to the outer wall of the threaded tube.

[0010] Furthermore, a threaded tube is provided at the bottom end of the second rod body, and a nut is threadedly connected to the outer wall of the threaded tube.

[0011] Furthermore, a protruding strip is fixedly connected to the inner wall of the first rod body. The width of the protruding strip is in tolerance with the gap width between the two gaskets, which is used to restrict the relative rotation of the first rod body and the second rod body.

[0012] Furthermore, a second protrusion is fixedly connected to the inner wall of the second rod body. The width of the second protrusion is in tolerance with the gap width between the two second washers, which is used to restrict the relative rotation of the second rod body and the third rod body.

[0013] This utility model has the following beneficial effects: In this invention, the overall weight is reduced by using an aluminum alloy pole body. Then, by tightening the nut, the symmetrical washers are strongly compressed and tightly fitted between adjacent pole bodies, forming local reinforcement at the connection point. This increases the effective wall thickness and support area at the connection point, thus meeting the lightweight requirements for children's use while avoiding the problem of pole body connection breakage due to improper operation when used by adults. This solves the contradiction between lightweight materials and insufficient connection strength.

[0014] In this invention, the gap between the two washers and the locking structure of the protrusion inside the shaft rigidly lock the two adjacent shaft sections together in a circumferential upward direction, eliminating the possibility of relative rotation between the shafts and effectively preventing unexpected rotation of the clubhead during use, thus ensuring the stability and accuracy of the hitting action.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-5This utility model provides an embodiment of an adjustable-length golf club, designed to meet the diverse usage needs of people of different heights. The club includes: a shaft 1, which serves as the outer foundation structure, supporting a shaft 2 and providing a primary telescopic channel; a shaft 2, forming the middle connecting structure of the club, connecting shaft 1 and shaft 3 and facilitating a secondary telescopic transition; and a shaft 3, forming the inner terminal structure of the club. Shafts 1, 2, and 3 are made of aluminum alloy, significantly reducing the overall weight of the club while maintaining structural strength, making it easier for children to hold and swing, thus improving the user experience; and spacers 10 and 20. 16. Shims 10 are symmetrically positioned between the inner wall of shaft 1 and the outer wall of shaft 2, and shims 26 are symmetrically positioned between the inner wall of shaft 2 and the outer wall of shaft 3. Shims 10 and 26 are used to reinforce the two connection points of the three shafts and prevent relative rotation between the shafts. Anti-slip shock absorber 4 is fitted on the top of shaft 1 to provide grip anti-slip function and absorb the vibration generated during the shot. Anti-slip shock absorber 4 is made of elastic anti-slip material, which improves grip comfort, safety and feel of the shot. Clubhead 17 is located at the bottom of shaft 3 to improve stability and control during the shot. Clubhead 17 adopts a hollow structure design. The hollow design is a common weight reduction design for golf club clubheads, which will not be described in detail here.

[0019] Specifically, shaft 1, in conjunction with shaft 2 and shaft 2, in conjunction with shaft 3, performs telescopic movements, thereby achieving stepless adjustment of the overall length of the club. This accommodates the diverse needs of users of different heights. Shim 10 is used to reinforce the connection between shaft 1 and shaft 2 and works with protrusion 7 to prevent relative rotation between the two. Shim 2 16 is used to reinforce the connection between shaft 2 and shaft 3 and works with protrusion 2 13 to prevent relative rotation between the two. This enhances the fracture resistance of the connecting shaft joints, solving the problem of easy breakage of aluminum alloy materials when used by adults. It also avoids inconvenience caused by rotation. During use, the user holds the anti-slip shock-absorbing sleeve 4 and performs the hitting operation through the clubhead 17.

[0020] Reference Figure 2 , Figure 3 and Figure 5The outer wall of the second pole body 2 has a locking hole 8. The inner wall of the gasket 10 is fixedly connected to the locking block 9. The outer wall of the locking block 9 is set inside the locking hole 8. The bottom end of the pole body 1 has a threaded tube 5. The outer wall of the threaded tube 5 is threadedly connected to the nut 6. The threaded tube 11 is tightened or loosened in conjunction with the nut 12 to facilitate adjustment of the relative length of the pole body as needed. The inner wall of the pole body 1 has a protruding strip 7. The protruding strip 7 is a longitudinal protrusion structure on the inner wall of the pole body 1. The width of the protruding strip 7 is in tolerance with the gap width between the two gaskets 10 to limit the relative rotation of the pole body 1 and the second pole body 2.

[0021] Specifically, nut 6 is threaded onto threaded tube 5 fixed to the bottom of shaft 1. When nut 6 is tightened, two shims 10 symmetrically arranged between shaft 1 and shaft 2 are compressed, causing shims 10 to fit tightly against the inner wall of shaft 1 and the outer wall of shaft 2. The tightly fitted shims 10 fill and reinforce the connection gap between shaft 1 and shaft 2, significantly enhancing the bending and impact resistance at the connection point. The convex strip 7 engages with the gap between the two shims 10 to lock them in place. Thus, based on the radial clamping force provided by the shims 10, the relative rotation between shaft 1 and shaft 2 is rigidly restricted. The locking block 9 engages with the locking hole 8 for positioning and anti-rotation, thereby limiting the circumferential movement of shims 10 on shaft 2 before length adjustment. This ensures that the position of shims 10 is fixed and that the gap between the two shims 10 is always accurately aligned with the convex strip 7 for locking.

[0022] Reference Figure 3 and Figure 4 The outer wall of the shaft 3 has a locking hole 14. The inner wall of the gasket 16 is fixedly connected to the locking block 15. The outer wall of the locking block 15 is set on the inner wall of the locking hole 14. The bottom end of the shaft 2 has a threaded tube 11. The outer wall of the threaded tube 11 is threadedly connected to the nut 12. The inner wall of the shaft 2 has a protruding strip 13. The protruding strip 13 is a longitudinal protrusion structure on the inner wall of the shaft 2. The width of the protruding strip 13 is in tolerance with the gap width between the two gaskets 16, which is used to limit the relative rotation of the shaft 2 and the shaft 3.

[0023] Specifically, nut 212 is threaded onto threaded tube 21, which is fixed to the bottom of shaft 22. When nut 212 is tightened, two washers 216, which are symmetrically arranged between shaft 22 and shaft 3, are compressed. The tightly fitting washers 216 fill and reinforce the connection gap between shaft 22 and shaft 3, significantly enhancing the bending and impact resistance of the connection. The protrusion 213 engages with the gap between the washers 216 to lock them in place. Thus, based on the radial clamping force provided by the washers 216, the relative rotation between shaft 22 and shaft 3 is rigidly restricted. The locking block 215 engages with the locking hole 214 for positioning and anti-rotation, thereby restricting the circumferential movement of washers 216 on shaft 33 before adjusting the length. This ensures that the position of washers 216 is fixed and that their gap is always accurately aligned with the protrusion 213 for locking.

[0024] Working principle: When the length of the golf club needs to be adjusted to suit users of different heights, first loosen nuts 1-6 and 2-12 to release the fixing constraints on shaft 1-1 and shaft 2-2, and shaft 2-2 and shaft 3-3. Then, pull or push shaft 2-2 relative to shaft 1-1 and shaft 3-3 relative to shaft 2-2 as needed until the club reaches the required length. Then tighten nut 1-6 to press it against threaded tube 1-5, thereby compressing the symmetrical washer 1-10 and making it fit tightly against shaft 1-1 and shaft 3-2. Between the two shims 10 and the shaft 1, the shaft is secured by the gap between the two shims 10 and the protrusion 7 inside the shaft 1. Similarly, tighten the nut 12 to press it against the threaded tube 11, thereby squeezing the symmetrical shims 16 and making the shims 16 fit tightly between the shaft 2 and shaft 3. Then, the shaft is secured by the gap between the two shims 16 and the protrusion 13 inside the shaft 2, thus fixing the relative position of each shaft and completing the length adjustment. When in use, the user holds the anti-slip shock-absorbing sleeve 4 and performs the hitting operation through the clubhead 17.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
