[0022] The specific implementation of the present application will be described below with reference to the accompanying drawings.

[0023] As shown in the accompanying Figures 1 to 3 , a stable badminton racket includes a racket frame 1, a middle tube 2, and a T-shaped joint 4 arranged at the joint of the racket frame 1 and the middle tube 2, and a handle 3 is arranged at the rear end of the middle tube 2, which is used to hold the badminton racket, wherein the T-shaped joint 4 includes a horizontal connecting part 41, a vertical connecting part 42, and a connecting part 46.

[0024] As shown in the accompanying Figure 2 , Figure 3 , Figure 4 and Figure 6 , the vertical connecting part 42 is matched with the inner tube wall of the middle tube 2, the front end of the vertical connecting part 42 is connected to the bottom surface of the horizontal connecting part 41, two mutually symmetrical clamping blocks 43 are arranged on the circumferential outer side of the rear end of the vertical connecting part 42, and a gap 44 is arranged through the circumferential outer side of the rear end of the vertical connecting part 42, which is located between the two clamping blocks 43, and two mutually symmetrical clamping grooves 21 are arranged through the outer tube wall of the front end of the hollow middle tube 2, and the clamping blocks 43 are matched with the clamping grooves 21. When the T-shaped joint 4 is spliced with the middle tube 2, the vertical connecting part 42 is inserted into the middle tube 2, and the vertical connecting part 42 on both sides of the gap 44 drives the two clamping blocks 43 to elastically shrink during the process, and the clamping blocks 43 are clamped in the clamping grooves 21 of the middle tube 2, that is, a clamping structure is formed, so that the spliced T-shaped joint 4 and the middle tube 2 are difficult to be directly pulled apart, and at the same time, the inner wall of the clamping groove 21 plays a limiting role on the outer wall of the clamping block 43, thereby enhancing the connection stability and firmness between the T-shaped joint 4 and the middle tube 2, avoiding the T-shaped joint 4 from being separated from the middle tube 2 in the subsequent process of being connected with the racket frame 1 to form a shape, improving the anti-separation ability, and improving the torsion support of the racket, making the ball hitting more stable and powerful, thereby enhancing the ball hitting stability of the badminton racket, and making the racket truly high-strength integration, which is not easy to deform. The vertical connecting part 42 is made of elastic material, specifically synthetic plastic, which has good toughness and can be deformed but not easily broken under stress.

[0025] It is worth mentioning that, as shown in the accompanying Figure 3 and Figure 4 , the horizontal connecting part 41 is matched with the outer tube wall of the middle tube 2, the front end of the horizontal connecting part 41 is connected to the top surface of the vertical connecting part 42, and the rear end of the horizontal connecting part 41 is connected to the connecting part 46.As shown, the front end face of the middle tube 2 is provided with two inwardly recessed grooves 22. The grooves 22 are formed on the inner wall of the middle tube 2, and the two grooves 22 are respectively connected to the two slots 21. When the vertical connecting part 42 is inserted into the middle tube 2, the two locking blocks 43 slide down along the two grooves 22 until the locking blocks 43 are inserted into the slots 21. During the process, the inner wall of the groove 22 guides the sliding of the locking blocks 43, so that the locking blocks 43 can be quickly and accurately inserted into the slots 21 without adjusting the insertion angle of the vertical connecting part 42, thus speeding up the assembly. Furthermore, the outer circumferential surface of the front end of the vertical connecting part 42 is provided with two mutually symmetrical sliders 45. The two sliders 45 correspond to the two locking blocks 43, and the sliders 45 are adapted to the grooves 22. During the process of the vertical connecting part 42 being inserted into the middle tube 2, the slider 45 is also gradually inserted into the slide groove 22. When the locking block 43 is locked in the locking groove 21, the slider 45 is inserted into the slide groove 22. At this time, the contact area between the vertical connecting part 42 and the middle tube 2 is increased. At the same time, the inner wall of the slide groove 22 can effectively limit the outer wall of the slider 45 to enhance the connection stability between the middle tube 2 and the T-type connector 4, and further prevent the T-type connector 4 from detaching from the middle tube 2 during the subsequent connection and forming process with the frame 1.

[0026] Additionally, as attached Figures 3 to 7 As shown, the front end of the middle tube 2 is provided with a horizontally arranged connecting shaft 23. Both ends of the connecting shaft 23 are connected to the inner wall of the middle tube 2, and the middle section of the connecting shaft 23 is broken to form a notch 25. A connecting part 46 is provided in the notch 44, which is adapted to the notch 25. During the process of the vertical connecting part 42 being inserted into the middle tube 2, the connecting shaft 23 is gradually placed into the notch 44. When the locking block 43 is locked in the locking groove 21, the connecting part 46 is just inserted into the notch 25. Then the connecting part 46 and the connecting shaft 23 are connected by screws 5. Specifically, a first threaded hole 24 is opened on the outer wall of the middle tube 2, which extends into the interior of the connecting shaft 23. A second threaded hole 461 is opened on the connecting part 46. After the connecting part 46 is inserted into the notch 25, the first threaded hole 24 and the second threaded hole 461 overlap. Then, the screw 5 is threaded into the first threaded hole 24 and the second threaded hole 461, thereby connecting and fixing the connecting part 46 and the connecting shaft 23 together. This further enhances the stability and firmness of the connection between the T-joint 4 and the middle tube 2, preventing the T-joint 4 from detaching from the middle tube 2 during the subsequent connection and forming process with the frame 1, and improving the anti-detachment capability. Among them, the horizontal connecting part 41, the vertical connecting part 42, the locking block 43, the connecting part 46, and the slider 45 are integrally formed without connecting gaps, making them less prone to breakage during use and exhibiting high mechanical strength.

[0027] In addition, as attached Figure 6 and Figure 7As shown, a countersunk hole 26 is opened on the outer tube wall of the middle tube 2. The countersunk hole 26 corresponds to the first threaded hole 24. When the screw 5 is screwed into the first threaded hole 24 and the second threaded hole 461, the head 51 of the screw 5 is placed in the countersunk hole 26 to prevent the head 51 of the screw 5 from protruding on the outer tube wall of the middle tube 2, which would affect the subsequent coating of the carbon fiber outer layer and the feel of use.

[0028] In summary, when using this utility model, during the splicing of the T-joint 4 and the middle tube 2, the vertical connecting part 42 is inserted into the middle tube 2. During the process, the vertical connecting parts 42 on both sides of the notch 44 drive the two locking blocks 43 to elastically retract until the locking blocks 43 are locked in the locking groove 21 of the middle tube 2, thus forming a locking structure. This makes it difficult to directly pull apart the spliced ​​T-joint 4 and the middle tube 2. At the same time, the connecting part 46 is just inserted into the notch 25. Then, the connecting part 46 and the connecting shaft 23 are connected and fixed by the screw 5, which enhances the connection stability and firmness between the T-joint 4 and the middle tube 2, and prevents the T-joint 4 from detaching from the middle tube 2 during the subsequent connection and forming process with the racket frame 1, thus improving the anti-detachment ability. In the formed badminton racket, the T-joint 4 is built into the joint between the racket frame 1 and the middle tube 2, which improves the torsional support of the racket, making the shot more stable and powerful, thereby enhancing the hitting stability of the badminton racket and making the racket truly high-strength integrated and not easy to deform. During the process of inserting the vertical connecting part 42 into the middle tube 2, the two locking blocks 43 slide down along the two sliding grooves 22 until the locking blocks 43 are inserted into the slots 21. The inner wall of the sliding grooves 22 guides the sliding of the locking blocks 43, so that the locking blocks 43 can be quickly and accurately inserted into the slots 21 without adjusting the insertion angle of the vertical connecting part 42, thus speeding up the assembly.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
