Quick connector

Abstract

A quick connector is provided, including: a tubular body, a tubular wall of the tubular body defining a channel, the channel defining an extension direction, the tubular body including at least one first through hole and at least one second through hole which is an elongate in the extending direction; a valve assembly, configured to releasably block the channel; an inner blocking member, movably received in the channel; at least one first detent member, received in the at least one first through hole and radially displaceable; at least one second detent member, received in the at least one second through hole and radially displaceable; a slidable sleeve, movably sleeved on the tubular body and movable to a first position or a second position, including at least one leg extending in the extending direction and radially corresponding to the at least one second through hole; an elastic urging assembly, disposed between the tubular body and the slidable sleeve, configured to urge the at least one first detent member and the at least one second detent member; wherein when the slidable sleeve is located in the first position, the inner blocking member radially blocks the at least one first detent member and the at least one second detent member inside the tubular wall of the tubular body, the elastic urging assembly radially blocks the at least one first detent member outside of the tubular wall of the tubular body, and each of the at least one leg corresponds radially to an upper portion of one of the at least one second through hole and does not radially block the at least one second detent member; wherein when the slidable sleeve is in the second position and the inner blocking member does not radially block the at least one first detent member inside the tubular wall of the tubular body, each of the at least one leg corresponds radially to a lower portion of one of the at least one second through hole and radially blocks the at least one second detent member so that the at least one second detent member protrudes within the channel.
