Description

Technical Field

[0001] The utility model relates to the technical field of quick-insertion joints, in particular to a spring-type double-sealed hinged quick-insertion joint. Background Art

[0002] Quick-connect connectors are an accessory that connects products. They have the advantage of achieving seamless connection between many products. Quick-connect connector assemblies are currently widely used in vehicle pipeline systems. Quick-connect connector assemblies generally include quick-connect connectors and quick-connect plugs. When in use, the quick-connect plug is inserted into the quick-connect connector, and the corresponding buckle structure is used to achieve buckle fixation, thereby realizing the quick-connect function. Through the connection of the quick-connect connector, the product connection is stable and will not cause water leakage, air leakage or electrical leakage.

[0003] Existing articulated quick-connect connectors have only one layer of sealing ring inside, which has a poor sealing effect, and the connector and the connector are usually fixed by a snap-fit ​​structure, which may cause the connector and the connector to become loose, affecting the sealing.
