ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a pipe connector.
BACKGROUND OF THE INVENTION
As illustrated in
FIG. 1
, a prior art pipe connector is very primitive at best. There are currently a variety of modern pipe connectors, which are rather complicated in construction and are therefore inefficient. In addition, the conventional pipe connectors are not provided with an effective means to prevent a leak.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a quick pipe connector which is simple in construction and is leakproof.
The pipe connector of the present invention comprises a threaded tube, two inner tubes, and two fitting tubes. The two inner tubes are held by two ends of the threaded tube. The two fitting tubes are engaged with the two ends of the threaded tube such that the inner tubes are fitted into the fitting tubes in conjunction with an elastic piece.
The foregoing objective, features, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
