Background

The patent document of China patent application No. 201921878369.7 discloses a technical scheme named as a pipe assembly with a novel anti-drop sealing structure. The socket section of the scheme comprises a large wave crest structure which is circumferentially arranged along the axial direction and a corrugated structure which is connected between the pipe and the large wave crest structure, wherein the peripheral wall of the corrugated structure is formed by alternately arranging wave crests and wave troughs in sequence along the axial extension direction; the first conical sealing section of the scheme is formed by the peripheral wall of the large crest structure, and the anti-falling piece mounting groove is formed by one trough adjacent to the large crest structure in the corrugated structure. Because the corrugated structure and the large crest structure are formed by outwards protruding outer layers of the socket sections, the corrugated structure and the large crest structure are hollow structures, and the thickness of the outer layers of the socket sections is limited, the structural strength of the corrugated structure and the large crest structure is very limited, and the limiting effect of the anti-falling part mounting groove on the anti-falling part is weaker.
