[0002] Existing direct drinking water pipelines are generally equipped with pipeline connectors to ensure smooth and leak-free transmission of water between pipelines. Pipe connectors generally include two connecting pipes, buckles and seals. The two connecting pipes are tightly connected together through the elastic structure or locking mechanism inside the buckle. The seal is arranged between the connecting pipes and the buckle to prevent water leakage and ensure water quality hygiene.
