[0039] See Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present utility model provides a foamed middle tube for a badminton racket, which is used to connect a racket handle 1 and a racket frame connector 2. One end of a racket rod main body 3 is provided with a convex first clamping portion 4, and the other end is provided with a convex second clamping portion 5. The racket rod main body 3 is respectively buckled and connected with the racket handle 1 and the racket frame connector 2 through the first clamping portion 4 and the second clamping portion 5;

[0040] The racket rod main body 3 includes a foamed layer 31 in the shape of a hollow cylinder and a carbon fiber layer 32 wrapped on the surface of the foamed layer 31. An inner clamping layer 33 is provided on the inner surface of the foamed layer 31, and an outer clamping layer 34 is provided on the surface of the carbon fiber layer 32. Among them, the inner clamping layer 33 and the outer clamping layer 34 are detachable layers. The inner clamping layer 33 can be an iron core, and the outer clamping layer 34 can be an OPP tape.

[0041] With the above structure, by respectively providing the first clamping portion 4 and the second clamping portion 5 at both ends of the racket rod main body 3, the racket handle 1 and the racket frame connector 2 can be stably connected to prevent loosening during use. At the same time, by providing the inner clamping layer 33 and the outer clamping layer 34 on the racket rod main body 3, when the foamed layer 31 is foamed, the extrusion force between the foamed layer 31 and the carbon fiber layer 32 can be increased, so that the foamed layer 31 and the carbon fiber layer 32 are more closely combined, enhancing the rebound and shock absorption effects and reducing the vibration of the badminton racket during hitting.

[0042] In one embodiment, seeFigure 2 。Both the first clamping part 4 and the second clamping part 5 are in an annular structure. In practical applications, the annular structures of the first clamping part 4 and the second clamping part 5 can connect the handle 1 and the racket frame connector 2, making the connections around the handle 1 and the racket frame connector 2 the same, thus avoiding the phenomenon of local direction shaking.

[0043] In one embodiment, refer to Figure 1 、 Figure 2 and Figure 4 。A first transition part 6 is provided between the racket rod main body 3 and the first clamping part 4, and a first extension part 7 is provided at one end of the first clamping part 4 away from the first transition part 6.

[0044] The diameter of one end of the first transition part 6 gradually decreases towards the other end. The end with a larger diameter of the first transition part 6 is connected to the racket rod main body 3, and the other end is connected to the first clamping part 4.

[0045] A first connection groove 11 is provided on the handle 1. The first connection groove 11 includes a first connection groove part 111, a first transition groove part 112, a first clamping groove part 113, and a first extension groove part 114. The first connection groove part 111 matches the racket rod main body 3, the first transition groove part 112 matches the first transition part 6, the first clamping groove part 113 matches the first clamping part 4, and the first extension groove part 114 matches the first extension part 7. In practical applications, under the structure of the first transition part 6, the outer diameter of the first extension part 7 can be made smaller than that of the racket rod main body 3, so that the first extension part 7 can be easily embedded into the first connection groove 11, facilitating the quick guiding of the first clamping part 4 into the first clamping groove part 113 when installing the handle 1.

[0046] In one embodiment, refer to Figure 1 、 Figure 2 and Figure 5 。A second transition part 8 is provided between the racket rod main body 3 and the second clamping part 5, and a second extension part 9 is provided at one end of the second clamping part 5 away from the second transition part 8.

[0047] The diameter of one end of the second transition part 8 gradually decreases towards the other end. The end with a larger diameter of the second transition part 8 is connected to the racket rod main body 3, and the other end is connected to the second clamping part 5.

[0048] A second connection groove 21 is provided on the racket frame connector 2. The second connection groove 21 includes a second connection groove portion 211, a second transition groove portion 212, a second clamping groove portion 213, and a second extension groove portion 214. The second connection groove portion 211 is matched with the racket handle main body 3, the second transition groove portion 212 is matched with the second transition portion 8, the second clamping groove portion 213 is matched with the second clamping portion 5, and the second extension groove portion 214 is matched with the second extension portion 9. In actual use, the structure of the second transition portion 8 enables the outer diameter of the second extension portion 9 to be smaller than that of the racket handle main body 3, so that the second extension portion 9 can be easily embedded into the second connection groove 21, facilitating the quick guiding of the second clamping portion 5 into the second clamping groove portion 213 when installing the racket frame connector 2.
