AI Technical Summary
Traditional composite wound tube connections are prone to loosening and detachment, affecting the performance and safety of lithium batteries.
The design incorporates a support plate and a connecting airbag ring. The central connecting threaded column and the telescopic moving arc plate are controlled by adjusting the knob. The connecting airbag ring, made of rubber, increases airtightness and friction, ensuring the stability of the connection.
It improves the connection stability of the flanged composite core tube for lithium batteries, prevents loosening and falling off, and enhances structural strength and practicality.

Abstract
Claims
1. A flanged composite core tube for lithium batteries, comprising a composite core tube outer tube (1) and a support disc (2) provided on the side of the composite core tube outer tube (1); characterized in that The support plate (2) is provided with a toggle adjustment knob (9), a central connecting threaded column (10) is provided at the middle position of the toggle adjustment knob (9), a telescopic moving arc plate (11) is provided at the bottom position of the central connecting threaded column (10), a telescopic connecting body (12) is provided at the bottom position of the telescopic moving arc plate (11), and a connecting airbag ring (8) is provided at the outer and inner positions of the support plate (2). The connecting airbag ring (8) is connected to the telescopic connecting body (12) through a pipe. Toggle the toggle adjustment knob (9) can make the central connecting threaded column (10) move. The movement of the central connecting threaded column (10) can make the telescopic moving arc plate (11) move to squeeze or stretch the telescopic connecting body (12). After the telescopic connecting body (12) is squeezed, the internal gas will enter the connecting airbag ring (8) and cause it to expand.
2. The flanged composite core tube for lithium batteries of claim 1, wherein: The outer side of the toggle adjustment knob (9) is provided with texture, and the inner side of the toggle adjustment knob (9) is provided with an internal thread that matches the central connecting threaded post (10).
