Abstract:
1. A pipe quick release structure comprising: a first pipe configured for connecting a distal end of a third pipe and having at least one boss adapted to be formed on an outer periphery of the first pipe; a second pipe configured for connecting a distal end of a fourth pipe and having at least one first axial trough defined in an inner periphery of the second pipe to correspond to and movably and selectively receive therein the at least one boss of the first pipe; and a joint securely received in the second pipe and having at least one axial ledge formed on an outer periphery thereof to correspond to and movably received in the at least one first axial trough of the second pipe, at least one second axial trough defined in an inner periphery of the joint to receive therein the at least one boss of the first pipe and at least one recess defined to communicate with the at least one second axial trough to selectively position the at least one boss of the first pipe so as to selectively secure connection of the first pipe to the second pipe, wherein the joint further has at least one inclined hole defined to communicate with the at least one second axial trough, and the second pipe further has at least one inclined track in communication with the at least one first axial trough of the first pipe to selectively receive therein the at least one boss of the first pipe; wherein when the first pipe is engaged with the second pipe, the at least one second axial trough mates and coincides with the at least one inclined track to allow the at least one boss to slide into the inclined track, so that the at least one boss is tightly against the at least one recess to be securely positioned in the at least one inclined track; and wherein when the joint is pushed until the at least one second axial trough mates and coincides with the at least one inclined track, the at least one boss is free from limitation of the at least one recess of the joint and the first pipe is separable from the second pipe.
