[0010] As preferably, the air-tight partition of the inside and outside space of the filling column is realized by the sealing ring between the first step and the end of the filling column.

[0011] The utility model further sets up, the top of shell is connected with cover body, the cover body is used for the sealing ring between filling column and first step is pressed tightly.

[0012] As preferably, the cover body is connected to the shell and plays a role in fixing the filling column.

[0013] The utility model further sets up, the ring spacing of second step is provided with vent hole.

[0014] As preferably, the vent hole ensures that the gas can pass through the second step and enter the inside space of the shell evenly.

[0015] The utility model further sets up, the inside diameter of first step is greater than the diameter of filling column, and the top of filling column is provided with annular flange with the inside diameter of shell.

[0016] As preferably, the buffer layer between the filling column and the shell can smoothly enter the shell.

[0017] The utility model further sets up, and the air valve is installed at the bottom of shell.

[0018] As preferably, the impact on the air valve can be effectively reduced.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model fills high-pressure air in the shell structure of the baseball bat, fills the buffer structure in the inside of the shell, when the shell of the baseball bat is impacted by external force and is about to be deformed, the high-pressure gas in the inside of the shell can support the inner wall of the shell well, effectively relieves the deformation of the shell, can also relieve the vibration to a certain extent, improves the feeling of the player, effectively improves the deformation resistance of the baseball bat, and the baseball bat can be applied to high-intensity use scenarios.

[0021] The utility model sets up the filling column in the shell, uses the filling column to occupy most of the inside space of the shell, provides the installation position for the buffer structure, can greatly reduce the filling amount of high-pressure gas in the shell, and the top of the filling column and the shell can also achieve good air-tight effect when the cover body is closed, further enhances the structural strength of the baseball bat.

[0031] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as a limitation on the utility model.
