Abstract

The present invention provides a quick connector device that includes: a connector body that has two fluid hose connectors located at two ends and an injector port connector located at a middle bottom section thereof; a locking member that is inserted into and rotatably connected to the injector port connector of the connector body and detachably coupled to the injector port; and an o-ring that is coupled to the injector port connector of the connector body and provides a sealing to the injector port. The connector body includes a support rib and a receiving space that securely maintain the locked state and allow the technician to easily assemble/disassemble the device. The quick connector device allows the technician to determine whether the device is in the locked or unlocked state based on the angular position of the locking member.

First claim

1 . A quick connector device comprising:
a connector body that has two fluid hose connectors located at two ends and an injector port connector located at a middle bottom section thereof; a locking member that is inserted into and rotatably connected to the injector port connector of the connector body and detachably coupled to the injector port; an o-ring that is coupled to the injector port connector of the connector body and provides a sealing to the injector port; at least one elastic member that is located on outer side of the locking member and has cut-out ends; a bump that engages into a bump receiving space formed on the inner surface of the injector port and is disposed on outer side of the elastic member; a receiving space that is formed on an upper outer surface of the injector port connector of the connector body and allows the elastic member to elastically deform therein; and a support rib that is disposed on one side of the receiving space and prevents the elastic member from moving when the locking member is in a locked state.

2 . A quick connector device as recited in claim 1 , wherein the locking member includes a handle that is disposed on an upper side of the locking member and forms an integral portion of the locking member.

3 . A quick connector device as recited in claim 2 , wherein the handle includes rib receiving grooves formed on upper middle sides and upper middle front and back portions thereof, further comprising:
one or more catch ribs that are disposed on upper sides of the injector port connector of the connector body along a horizontal direction and correspond to the rib receiving grooves.

4 . A quick connector device as recited in claim 2 , wherein the locking member has second bump receiving spaces that are disposed along a vertical direction at front and back sides of the locking member and disposed on an inner surface of the locking member and wherein the injector port connector of the connector body includes second bumps that are disposed on left, right, front and back sides of the injector port connector and disposed on an upper outer surface of the injector port connector and correspond to the second bump receiving spaces.
