[0014] By adopting the above technical solution, the structural stability of the top is enhanced, and the reliability of the connection is further improved through mechanical interlocking, preventing the top plug from loosening or falling off during use.

[0015] Optionally, the top plug is made of glass fiber reinforced PEEK material.

[0016] By adopting the above technical solutions, while ensuring the structural strength of the top plug, better impact resistance and wear resistance can be provided, further improving the service life and reliability of the top plug.

[0017] Optionally, the bat body is provided with a tail plug at the tail end, and the tail plug is interference-fitted with the bat body.

[0018] By adopting the above technical solution, it is possible to effectively prevent the tail plug from loosening or falling off during use, thereby enhancing the structural stability of the bat tail and improving the overall performance.

[0019] Optionally, the interference fit between the tail plug and the bat body is 0.08 mm.

[0020] By adopting the above technical solution, it is possible to ensure that the tail plug is firmly fixed while avoiding assembly difficulties or material deformation caused by excessive interference, thereby further optimizing the fixing effect and service life of the tail plug.

[0021] In summary, this application includes the following beneficial technical effects: 1. By setting a reinforcing ring on the inner wall of the bat body and designing a gradual transition zone at both ends of the reinforcing ring, the local rigidity and wall thickness distribution of the sweet spot are significantly optimized, effectively extending the range of the sweet spot and improving the vibration damping effect during the shot, thereby improving the stability and accuracy of the shot; 2.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a baseball bat. (Refer to...) Figure 1 and Figure 2 The baseball bat includes a bat body 1. In this embodiment, the bat body 1 is made of 7075-T7351 aluminum alloy. The bat body 1 is 842mm long, has an outer diameter of 66.7mm, and a wall thickness of 3mm. A reinforcing ring 2 is provided on the inner wall of the bat body 1. The reinforcing ring 2 is located in the range of 2.5cm-19.5cm from the top of the bat body 1, so the length of the reinforcing ring 2 is 17cm. In some embodiments, the reinforcing ring 2 is made of aluminum alloy. The reinforcing ring 2 has transition zones 5 at both ends. The thickness of the transition zones 5 increases from 0.4mm at the ends to 1.5mm in the middle of the reinforcing ring 2. The length of the transition zones 5 at both ends is 1.5cm, meaning that the thickness of the middle section of the reinforcing ring 2 is consistent except for the transition zones at both ends. The reinforcing ring 2 and the transition zones 5 significantly optimize the local rigidity and wall thickness distribution of the sweet spot, effectively extend the range of the sweet spot, optimize stress distribution, and improve the vibration damping effect during impact, thereby improving the stability and accuracy of the shot.

[0027] In some embodiments, the reinforcing ring 2 is fixedly connected to the bat body 1 by welding. This allows it to better withstand the impact forces during high-intensity use, extending the service life of the baseball bat and solving the problem of insufficient connection strength in the prior art.

[0028] In some embodiments, the welding is laser welding, with a weld penetration depth ≥ 2 mm and a depth-to-width ratio ≥ 3:1. Specifically, in this embodiment, the weld penetration depth is 2.8 mm, and the depth-to-width ratio is 3.5:1. Using laser welding technology ensures sufficient weld penetration depth and depth-to-width ratio, further improving the reliability and stability of the connection.

[0029] Reference Figures 3-5 In some embodiments, the top of the bat body 1 is provided with a top plug 3, and a buckle 6 is provided around the end of the top plug 3. One end of the buckle 6 is in the shape of a barb. An annular locking groove 7 is provided on the inner wall of the bat body 1 near the top. The buckle 6 and the annular locking groove 7 are engaged with each other, so that the top plug 3 can be more stably fixed to the bat body 1.

[0030] In some embodiments, the top plug 3 is made of glass fiber reinforced PEEK (30%GF) material.

[0031] Continue to refer to Figure 3 and Figure 4 In some embodiments, the tail of the bat body 1 is provided with a tail plug 4, and the tail plug 4 is interference-fitted with the bat body 1. In this embodiment, the tail plug 4 is made of 7075-T7351 aluminum alloy. In some embodiments, the interference fit between the tail plug 4 and the bat body 1 is 0.08mm. This avoids assembly difficulties or material deformation caused by excessive interference, further optimizing the fixing effect and service life of the tail plug 4.

[0032] The implementation principle of a baseball bat according to an embodiment of this application is as follows: by setting a reinforcing ring 2 on the inner wall of the bat body 1 and designing a gradual transition zone 5 at both ends of the reinforcing ring 2, the local rigidity and wall thickness distribution of the sweet spot are significantly optimized, the range of the sweet spot is effectively extended, and the vibration attenuation effect during the hit is improved, thereby improving the stability and accuracy of the hit.
