Abstract
A pipe coupling structure for fluid includes a first and a second coupler connected end-to-end. The first coupler internally defines a shaft moving space having a diameter gradually increased axially inward from a through hole thereof, which is elastically closed by a first shaft supporting base. The second coupler internally defines a valve moving space for receiving a movable valve, which has a second through hole elastically closed by a second shaft head section. When the first coupler is pushed against the movable valve, the second shaft head section is projected forward from the through hole on the movable valve to pushes the first shaft supporting base backward to open the shaft moving space, so that the first and second couplers are internally fluidly communicable with each other. Since the shaft moving space has a gradually increased diameter, a fluid can flow therethrough at the same flowing speed.
