AI Technical Summary

Technical Problem

Existing baseball bats transmit vibrations to the batter's hand during impact, causing discomfort.

Method used

A threaded vibration-damping ball is designed. By setting a vibration-controlling layer between the ball's end cap and the main body, and using a threaded meshing structure for connection, the vibration-controlling layer has excellent vibration transmission and damping capabilities, absorbing and mitigating vibration, and reducing the transmission of vibration to the grip.

Benefits of technology

It effectively reduces vibration in the grip area of ​​the bat, improves hand comfort when hitting the ball, and the spiral-shaped vibration control layer further reduces vibration, enhancing the player's hitting experience.

Abstract

A threaded vibration-damping baseball bat, relating to the technical field of baseball bats. The threaded vibration-damping baseball bat comprises an end cap (20), a bat body (10) and a vibration control layer (23). The end cap (20) comprises a threaded portion (22), the outer peripheral wall of the threaded portion (22) being provided with external threads, and the bat body (10) comprises a cylindrical straight portion (11) located at the upper part and having a uniform diameter in an axial direction, the inner surface of the cylindrical straight portion (11) being provided with internal threads; the external threads and the internal threads form a threaded engagement structure, enabling coaxial connection between the end cap (20) and the bat body (10). The vibration control layer (23) is arranged between the external threads and the internal threads. The vibration control layer (23) can reduce vibrations felt at a grip portion (13), thereby improving the comfort of a player's hands during hitting.
