Abstract

A quick release connector has a body, a positioning mount, a sealing valve and an outer sleeve. The body is hollow and has a threaded end, a connecting end, an air inlet chamber, a mounting recess, a threaded segment, a sealing ring and a pressing ring. The positioning mount is detachably connected to the body and has a fixing end, an inserting end, an air outlet chamber, a returning spring, multiple ball holes and multiple balls. The sealing valve is movably mounted between the body and the positioning mount, selectively abuts the sealing ring of the body and has a closed end, an open end and at lease one air inlet. The outer sleeve is slidably mounted between the body and the positioning mount and has a mounting end, a pushing end, an internal surface, a spring recess, a holding recess and a pressing spring.

Claims

1. A quick release connector comprising:

a body being hollow and having

an external surface;

an internal surface;

a threaded end;

a connecting end formed with the threaded end of the body;

an air inlet chamber formed in the body near the threaded end and having a diameter;

a mounting recess formed in the body, communicating with the air inlet chamber and having

an internal surface;

a protruding face formed on the internal surface of body at the mounting recess near the air inlet chamber; and

a diameter smaller than the diameter of the air inlet chamber;

a threaded segment formed in the body near the connecting end and communicating with the mounting recess and the air inlet chamber;

a sealing ring mounted in the mounting recess of the body and abutting against the protruding face of the mounting recess; and

a pressing ring mounted in the mounting recess and abutting the sealing ring;

a positioning mount detachably connected to the body and having

an external surface;

an internal surface;

a fixing end inserted into the connecting end of the body, securely mounted in the threaded segment of the body to connect the positioning mount with the body and abutting against the pressing ring to hold the sealing ring securely mounting in the mounting recess of the body;

an inserting end formed with the fixing end;

an air outlet chamber formed in the positioning mount and communicating with the mounting recess and the air inlet chamber of the body;

a returning spring mounted in the air outlet chamber of the positioning mount, abutting the pressing ring and having two ends, one of the ends of the returning spring abutting the pressing ring;

multiple ball holes formed through the external surface of the positioning mount at intervals near the inserting end of the positioning mount, arranged in a circle around the positioning mount and communicating with the air outlet chamber; and

multiple balls respectively held in the ball holes in the positioning mount;

a sealing valve movably mounted between the body and the positioning mount, selectively abutting the sealing ring of the body and having

a closed end being enlarged and mounted in the air inlet chamber of the body and mounted through the sealing ring and the pressing ring to selectively close a passage between the air inlet chamber and the mounting recess of the body;

an open end mounted in the air outlet chamber of the positioning mount and communicating with the air outlet chamber; and

an external surface abutting the balls at the open end and the other end of the returning spring abutting the external surface of the sealing valve near the open end;

at lease one air inlet formed radially through the external surface of the sealing valve near the closed end and selectively communicating with the air inlet chamber of the body or the air outlet chamber of the positioning mount; and

an outer sleeve slidably mounted between the body and the positioning mount and having

a mounting end mounted around the body near the connecting end;

a pushing end mounted around the positioning mount near the inserting end;

an internal surface;

a spring recess formed in the internal surface of the outer sleeve at the mounting end and mounted around the body and the positioning mount;

a holding recess formed in the internal surface of the outer sleeve at the pushing end to hold the balls of the positioning mount inside; and

a pressing spring mounted around the positioning mount in the spring recess and abutting the connecting end of the body to make the balls hold between the holding recess, the ball holes and the external surface of the sealing valve at the open end.

2. The quick release connector as claimed in claim 1, wherein the positioning mount has multiple releasing holes formed through the external surface of the positioning mount at intervals between the fixing end and the ball holes and communicating with the air outlet chamber.

3. The quick release connector as claimed in claim 2, wherein the sealing valve has

a mounting ring mounted around the open end of the sealing valve and abutting the internal surface of the positioning mount;

and

a holding ring securely mounted around the mounting ring to prevent the sealing valve from escaping from the positioning mount via the inserting end of the positioning mount.

4. The quick release connector as claimed in claim 3, wherein the threaded end of the body has a thread formed in the internal surface of the body near the threaded end.

5. The quick release connector as claimed in claim 3, wherein the threaded end of the body has a thread formed on the external surface of the body near the threaded end.

6. The quick release connector as claimed in claim 2, wherein the threaded end of the body has a thread formed in the internal surface of the body near the threaded end.

7. The quick release connector as claimed in claim 2, wherein the threaded end of the body has a thread formed on the external surface of the body near the threaded end.

8. The quick release connector as claimed in claim 1, wherein the sealing valve has

a mounting ring mounted around the open end of the sealing valve and abutting the internal surface of the positioning mount;

and

a holding ring securely mounted around the mounting ring to prevent the sealing valve from escaping from the positioning mount via the inserting end of the positioning mount.

9. The quick release connector as claimed in claim 1, wherein the threaded end of the body has a thread formed in the internal surface of the body near the threaded end.

10. The quick release connector as claimed in claim 1, wherein the threaded end of the body has a thread formed on the external surface of the body near the threaded end.
