Abstract: A connector assembly includes a first connector and a second connector. The first connector includes a first connector body and a locking sleeve. The locking sleeve is rotatably retained on the first connector body and includes a locking slot and a guiding protrusion. The locking slot is provided in a tubular wall of the locking sleeve, and the guiding protrusion is arranged at an axial end of the tubular wall and is adjacent to the locking slot. The second connector includes a second connector body, and the second connector body includes a locking protrusion arranged at its outer periphery. During the insertion of the second connector body between the locking sleeve and the first connector body along the axial direction, the locking sleeve can rotate responsive to the locking protrusion pushing the guiding protrusion, allowing the locking protrusion to move along the guiding protrusion and into the locking slot.

Abstract: A quick connector includes: a connector body for an plug-in member to be inserted therein, the connector body including an indication part; a locking member including a locking leg for locking the plug-in member to the connector body, a movement of the locking leg from an unlocking position to a locking position including an axial movement along insertion direction of the plug-in member and a transverse movement toward the locking position along a transverse direction of the connector body; and a shielding sleeve sleeved outside the connector body. The shielding sleeve is actuated by the locking leg and moved relative to the connector body during the axial and transverse movements. The shielding sleeve is in an initial position when the locking leg is in the unlocking position and in an indication position when the locking leg is in the locking position.

Abstract: A quick connector comprises a sleeving component and a sliding lock. The sleeving component comprises a stop part configured to stop the automatic moving of the sliding lock toward the interior of the sleeve component in the transverse direction when a fluid pipeline is inserted into the sleeving component, and release the stopping of the sliding block when the fluid pipeline is completely pushed into a main body of the sleeving component. The sliding lock further comprises at least one locking hook, and the locking hooks matches a locking catch arranged in the main body of the sleeving component. When a fluid pipeline is completely pushed into the main body of the sleeving component, the locking hooks moves around the locking catch and finally surrounds the locking catch.

Abstract: A quick connection device with a double-checked locking mechanism includes a connection housing and a locking mechanism, the locking mechanism including a first locking mechanism inserted into the connection housing and having a pedestal from which a pair of retaining arms extends, the pair of retaining arms being connected by a connection strip to form a retaining ring for fitting with an opposite plug-in tube, and having an elastic reset component; and a second locking mechanism inserted into the connection housing having a base from which locking arms and holding arms extend, the first locking mechanism being inserted between the locking arms and the holding arms, wherein the locking arms support a portion of the first locking mechanism and the second locking mechanism prevents movement of the first locking mechanism from the locked position to an unlocked position when the second locking mechanism is in a locked position.
