Description

Technical Field

[0001] The utility model relates to the technical field of golf clubs, in particular to a golf club with a high-strength coating. Background Art

[0002] Golf clubs are basic equipment in golf, consisting of a head, a shaft and a grip. According to the different uses of the clubs, the clubs are designed with different head shapes and shaft lengths, so golf clubs can be roughly divided into woods, irons, wedges and putters. Usually, golf clubs need to be assembled with the head, shaft and grip when used.

[0003] In order to facilitate the partial replacement and assembly of golf clubs, the prior art has made many improvements to golf clubs. For example, the patent with patent publication number CN219398891U discloses a carbon fiber golf club with a protective film, including a shaft and a ball head arranged at the bottom end of the shaft. A mounting mechanism is arranged at the connection between the shaft and the ball head, and the mounting mechanism is composed of a threaded groove, a threaded column, and a fixed groove. The threaded groove is opened at the top end of the ball head, the fixed groove is opened at the top end of the threaded groove, the threaded column is arranged on the inner side of the threaded groove, and the top end of the threaded column is fixed to the bottom end of the shaft. Through the designed mounting mechanism, the problem that the original carbon fiber golf club cannot be replaced separately after long-term use due to the integral structure of the carbon fiber golf club when the local damage occurs is improved. By arranging the mounting mechanism at the connection between the shaft and the ball head, the carbon fiber golf club can be disassembled according to the demand, so as to meet the need of partial replacement of the carbon fiber golf club after long-term use.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] The above-mentioned comparative document limits the threaded column after it is installed in the thread groove through the installation mechanism. However, since the thread of the threaded column will become loose after being installed in the thread groove, all the force will be transferred to the installation mechanism after the threaded column and the thread groove become loose. When the golf club is used to hit the ball hard, a strong torque will be generated on the installation mechanism, and then the installation mechanism will break, making the golf club easily damaged. Therefore, the field is in urgent need of improving the golf club to solve the defects of the existing technology. Utility Model Content
