Abstract
The utility model discloses a self-closing quick lock joint and a self-closing connecting plug. A one-way valve is arranged in each of a lock joint and the connecting plug of the quick joint, so that the quick joint has a double-end self-closing sealing function. Under the condition that the connecting plug is unplugged, the lock joint and the connecting plug are sealed in a self-closing mode by the one-way valves, so that gas leakage is prevented. When the connecting plug is plugged, one-way valve cores in the lock joint and the connecting plug push each other to open the one-way valves, so that the gas can circulate. When the quick joint is used for connecting a pipeline, the operation is very convenient and quick, and gas leakage can be prevented.
