A protective sheath is machined inside a string slot, a connecting wire is installed inside, a first string is installed, and a first and second string protection frames are installed. The protective sheath and the strings are completely hidden within the string slot, which not only serves an aesthetic purpose but also, more importantly, solves the problem of string breakage caused by friction during play and receiving. Furthermore, when the racket frame needs to be replaced, the racket frame can be removed by rotating a threaded post within the mounting slot.

[0003] According to the disclosed technical solution, the badminton racket in the prior art forms a mesh structure by having a single racket string pass back and forth from the side of the racket frame. In addition to the impact force generated by the contact between the racket net and the badminton during the hitting process, which may cause the racket string to break, the friction generated by the racket string on the side of the racket frame contacting the ground is more likely to cause the racket string to break. Conventional badminton rackets lack a protective structure for the side racket strings, and the center of gravity position of different badminton rackets is fixed and cannot be adjusted.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The present invention provides the following technical solution: a badminton racket with anti-breaking strings, comprising a racket body, the racket body comprising a racket frame 1, a racket shaft 3, a center of gravity adjustment assembly 4, and a replacement assembly 5. The racket frame 1 has strings 2 inserted into its inner side, the racket frame 1 having the racket shaft 3 integrally formed at its rear end, the racket shaft 3 being sleeved at its distal end with the center of gravity adjustment assembly 4, the replacement assembly 5 being sleeved on its outer side with a hand grip 15 wrapped around its surface, and the replacement assembly 5 and the center of gravity adjustment assembly 4 being locked and connected. This anti-breaking badminton racket can shield and protect the racket strings 2 outside the racket frame 1, and allows for quick replacement of the hand grip 15 and adjustment of the center of gravity position.

[0024] When the present invention is used, after the racket strings 2 pass through the side of the racket frame 1, multiple blocking pieces 10 are used to enclose the racket strings 2 on the outside of the racket frame 1, so that wear on the racket strings 2 can be avoided when the edge of the racket frame 1 hits the ground. At the same time, the replacement component 5 can be directly removed by removing the locking screw 14 at the tail end. Therefore, the hand grip 15 that has been wound can be directly replaced without removing the hand grip 15, so that the replacement of the hand grip 15 is more efficient and convenient, and the center of gravity position adjustment function of the racket shaft 3 is realized with the help of the center adjustment component.

[0025] In this embodiment, the racket frame 1 has a groove 6 formed on its side. A slot 8 is formed along its edge. A baffle 10 is inserted into the slot 8, and a retaining plate 9 is integrally formed at one end of the baffle 10. A string hole 7 is formed in the racket frame 1 within the groove 6. The string 2 passes through the hole 7 and is concealed within the groove 6. The baffle 10 presses against the surface of the string 2, and one side of the retaining plate 9 abuts against the side of the racket frame 1. Multiple baffles 10 are provided on the side of the racket frame 1. After a new string 2 is passed through the string hole 7 in the racket frame 1, the baffles 10 are inserted into the side of the racket frame 1 to block the string 2. This protects the strings 2 on the side of the racket frame 1, preventing them from colliding with the ground and reducing the likelihood of string breakage.

[0026] Specifically, the racket string 2 passes through the threading hole 7 on the side of the racket frame 1, and after passing through, the baffle 10 is manually passed through the slot 8 above the area where the racket string 2 passes until the clamping plate 9 is pressed against the side of the racket frame 1. At this time, the top baffle 10 can partially cover the outside of the racket string 2, thereby providing shielding protection for the racket string 2 with the help of the baffle 10.

[0027] In this embodiment, the center of gravity adjustment assembly 4 includes a tail rod 16, a screw rod 18, and a counterweight column 19. One end of the tail rod 16 is integrally formed with a limiting collar 17. A rotating plate 20 is mounted on the other end of the tail rod 16. One end of the screw rod 18 is embedded in the inner side of the rotating plate 20. The other end of the screw rod 18 is embedded in the inner wall of the racket shaft 3. Threaded holes are defined in the center of the counterweight column 19 and in the middle of the outer side of the rotating plate 20. The screw rod 18 passes through the threaded hole in the center of the counterweight column 19. A keyway 22 is defined on the surface of the counterweight column 19. A ridge on the inner wall of the racket shaft 3 engages with a groove 6 on the surface of the counterweight column 19. A gap is provided between the side edges of the counterweight column 19 and the inner wall of the racket shaft 3, allowing the counterweight column 19 to move along the interior of the racket shaft 3. A screw rod 18 and a counterweight column 19 are inserted into the racket shaft 3, and the screw rod 18 can be driven to rotate by manually rotating the rotating plate 20 at the end, thereby controlling the internal counterweight column 19 to move inside the racket shaft 3, thereby achieving the function of adjusting the center of gravity.

[0028] Specifically, when adjusting, the outer replacement component 5 is first disassembled. At this time, the rotating plate 20 at the end can be directly exposed to the outside. Therefore, by manually controlling the rotating plate 20 to rotate, the inner screw rod 18 can be driven to rotate. The counterweight column 19 on the screw rod 18 is stuck on the raised structure on the inner wall of the racket shaft 3 through the key groove 22 on the side. Therefore, the counterweight column 19 can only move in a straight line along the inside of the racket shaft 3 without rotating. At this time, the position of the counterweight column 19 can be changed to achieve the purpose of adjusting the center of gravity of the racket shaft 3.

[0029] In this embodiment, the replacement component 5 includes a hand grip 15 and an outer sleeve 11. The surface of the outer sleeve 11 is provided with a plurality of protrusions 21. The hand grip 15 is wrapped around the surface of the outer sleeve 11, and the hand grip 15 covers each protrusion 21. End plates 12 are integrally formed at both ends of the outer sleeve 11, and a plug-in block 13 is integrally formed on the surface of one of the end plates 12. The plug-in block 13 is used to be embedded in a hole pre-opened on one side of the limiting protrusion 17. A locking screw 14 is inserted in the middle of the end plate 12 at the tail end of the outer sleeve 11. The locking screw 14 passes through the middle of the end plate 12 and is embedded in a threaded hole pre-opened on the surface of the rotating plate 20. The outer sleeve 11 is used to be sleeved on the surface of the tail rod 16. The hand grip 15 can be quickly replaced through the external replacement component 5, and after the replacement is completed, the replacement component 5 and the inner center adjustment component are locked at the same time with the help of the locking screw 14 at the rear end to ensure that the hand grip 15 and the inner adjusted counterweight column 19 can remain stable during strenuous exercise, making the replacement of the hand grip 15 part simpler and more convenient.

[0030] Specifically, by directly wrapping the hand grip 15 around the surface of the outer sleeve 11, it is only necessary to sleeve the outer sleeve 11 on the tail rod 16, and embed the plug-in block 13 on the end plate 12 at the front end of the outer sleeve 11 into one side of the limiting protrusion 17, and then use the locking screw 14 to pass through the other end plate 12 and embed it into the threaded hole on the rotating plate 20, so as to realize the installation process of the replacement component 5. When it is necessary to replace the hand grip 15 of other specifications in the future, there is no need to remove the old hand grip 15 and it can be directly replaced.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
