[0014] Figure 4 It is a schematic diagram of the three-dimensional structure of a badminton racket in an unfolded state.

[0015] Figure 5 It is a schematic diagram of the three-dimensional structure of a badminton racket in a folded state. DETAILED DESCRIPTION

[0016] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0017] As attached Figure 1 As shown, a foldable badminton racket comprises a racket frame 1, a grip 3 and a middle tube 2 connecting the racket frame 1 to the grip 3. The racket frame 1 is formed in a ring shape, and strings are passed through the racket frame 1 through string pins for hitting the ball.

[0018] It is worth mentioning that, as Figure 1 、 Figure 2 and Figure 5As shown, the middle tube 2 includes an upper tube 21, a connecting tube 22, and a lower tube 23. The upper tube 21 and the lower tube 23 are respectively hinged to the ends of the connecting tube 22. The other end of the upper tube 21 is connected to the racket frame 1, and the other end of the lower tube 23 is connected to the grip 3. During use, the state of the badminton racket can be changed by rotating the upper tube 21, the connecting tube 22, and the lower tube 23. Specifically, when the upper tube 21, the connecting tube 22, and the lower tube 23 are rotated until their axes are all aligned, the badminton racket is in the unfolded state, suitable for hitting the ball and playing sports. When the upper tube 21, the connecting tube 22, and the lower tube 23 are rotated so that the racket frame 1 and the grip 3 overlap, the badminton racket is in the folded state, which is compact, takes up little space, and is easy to carry.

[0019] As attached Figures 2 to 5 As shown, the unfolded state of the badminton racket is fixed by a connecting member 4. Specifically, the connecting member 4 includes a connecting sleeve 41, which is movably mounted on the outside of the upper tube 21 and the connecting tube 22. The through hole 411 on the connecting sleeve 41 is provided with an internal thread at one end near the lower tube 23 to form a threaded hole, and the lower tube 23 is provided with an external thread at one end near the connecting tube 22 to form a threaded rod 231. When the upper tube 21, the connecting tube 22 and the lower tube 23 are rotated until their axes are all on the same straight line, the connecting sleeve 41 is moved downward along the upper tube 21 and sleeved on the outside of the connecting tube 22 until the threaded rod 231 contacts the threaded hole, and then the connecting sleeve 41 is rotated to thread the threaded rod 231 and the threaded hole. During the process, since the connecting sleeve 41 is adapted to the upper tube 21 and the connecting tube 22, and the length of the connecting sleeve 41 is greater than the sum of the lengths of the connecting tube 22 and the threaded rod 231, when the connecting sleeve 41 is fixed on the lower tube 23 by threads, the connecting sleeve 41 can still be sleeved on the outside of the upper tube 21 and the connecting tube 22. The limiting effect of the connecting sleeve 41 on the lower tube 23, the upper tube 21 and the connecting tube 22 can make the lower tube 23, the upper tube 21 and the connecting tube 22 fixedly connected together, thereby ensuring the use of the badminton racket. The connecting sleeve 41 is made of metal, specifically stainless steel, which has high strength and is not easy to be damaged, thereby ensuring the stability of the badminton racket in the unfolded state. After the connecting sleeve 41 is installed, the strength of the middle tube 2 can also be guaranteed.

[0020] In addition, as attached Figure 3 As shown, the cross-section of the connecting sleeve 41 is a polygonal structure, so that the edges on the outer surface of the connecting sleeve 41 can increase the friction between the connecting sleeve 41 and the fingers, making it easier to rotate the connecting sleeve 41 and complete the installation and removal of the connecting sleeve 41. Furthermore, the cross-section of the connecting sleeve 41 can be a regular hexagonal structure. In this case, the connecting sleeve 41 can be rotated with a hexagonal wrench, making it easier to operate the connecting sleeve 41.

[0021] In addition, as attached Figure 3As shown, an outwardly protruding stopper 43 is provided on the outer side of one end of the connecting sleeve 41 near the lower tube 23. When the connecting sleeve 41 is rotated, the stopper 43 is used to abut against the finger. The provision of the stopper 43 can prevent the hand from slipping during the rotation of the connecting sleeve 41, thereby facilitating the rotation of the connecting sleeve 41. The connecting sleeve 41 and the stopper 43 are integrally formed by injection molding and are not easily broken.

[0022] In summary, when using the present invention, the upper tube 21, the connecting tube 22, and the lower tube 23 are rotated until their axes are all aligned. The connecting sleeve 41 is then moved downwardly along the upper tube 21 and sleeved onto the outer side of the connecting tube 22 until the threaded rod 231 contacts the threaded hole. The connecting sleeve 41 is then rotated to thread the threaded rod 231 into the threaded hole. At this point, the connecting sleeve 41 can still be sleeved onto the outer sides of the upper tube 21 and the connecting tube 22. The restraining effect of the connecting sleeve 41 on the lower tube 23, the upper tube 21, and the connecting tube 22 can be used to securely connect the lower tube 23, the upper tube 21, and the connecting tube 22, thereby maintaining the badminton racket in an unfolded state for use in hitting a ball or playing sports. When use is complete, the connecting sleeve 41 can be rotated to separate the connecting sleeve 41 from the lower tube 23, then moved to the outer side of the upper tube 21. Finally, the connecting tube 22 and the lower tube 23 are rotated to overlap the racket frame 1 and the grip 3. The badminton racket is now in a folded state, compact, and convenient to carry. Furthermore, the upper tube 21 , the connecting tube 22 , the lower tube 23 and the connecting sleeve 41 in the present invention are connected to each other and are not easily lost.

[0023] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
