Document Type and Number:
WIPO Patent Application WO/2017/067348
Kind Code:
A1
Abstract:
A connection structure of a gas pipe, comprising a connector (1). One end of the connector (1) is provided with a connecting portion (11), a rubber tube (2) is sheathed around the connecting portion (11), the external portion of the rubber tube (2) is provided with a riveting sleeve (3) for fixing the rubber tube (2) to the connecting portion (11), and an anti-rotation structure (5) for preventing the rubber tube (2) from rotating is arranged between the riveting sleeve (3) and the connecting portion (11). The anti-rotation structure (5) enables that the riveting sleeve (3) and the connecting portion (11) cannot rotate after being fitted together, so that the gas pipe does not have the problem of gas leakage due to rotation. The connection structure is simple in structure, convenient in manufacturing, and low in costs.
