Abstract: A wedge clamp quick release connector has a main body, a positioning mount, and a quick connecting device. The quick connecting device has a sliding sleeve, at least one wedge clamp and a sleeve spring. The sliding sleeve has a spring recess and a clamp recess. Each wedge clamp is moveably held in the positioning mount, and has a stop portion and a wedge portion. The stop portion has an external surface and a stop plane, and the wedge portion protrudes from a middle of the stop plane and has an internal surface opposite the external surface and two bevels formed on two edges of the internal surface. The sleeve spring is mounted in the spring recess of the sliding sleeve. The engagement between the connector and a corresponding plug is in reliable surface contact by corresponding bevels of each wedge clamp and the plug.

Abstract: A quick connect fitting has a coupling assembly, a socket assembled on the coupling assembly, multiple blocking balls, multiple locking balls, and an operating assembly. The multiple blocking balls and the multiple locking balls are mounted in the socket. The operating assembly is mounted around the socket and has a first operating sleeve, a first compression spring, a second operating sleeve, and a second compression spring. The first operating sleeve is blocked by the multiple locking balls. The first compression spring abuts against both the first operating sleeve and the coupling assembly. The second operating sleeve is blocked by the multiple blocking balls. The second compression spring abuts against both the first operating sleeve and the second operating sleeve. Operating the first operating sleeve and the second operating sleeve sequentially can safely remove a plug.

Abstract: A safety type quick connector has a body, a socket base, a moving base, a pushing assembly, an outer sleeve, multiple springs, multiple first balls and second balls. The socket base is connected to the tubular body and has an inserting end, a connecting end, multiple ball slots and ball bores. The moving base is movably mounted in the socket chamber and has a closed end, an open end, a sealing flange, multiple ball holes and at least one vent. The sealing flange is formed around the closed end and abuts against and closes the connecting end of the socket base. The pushing assembly is movably mounted in the moving base.
