<p>PROBLEM TO BE SOLVED: To provide a quick hose coupling eliminating stress deformation of a hose, protecting the hose and preventing its rupture due to repetitive bending.SOLUTION: An upper connecting segment 11 comprises a lock mechanism and a connecting passage. A lower connecting segment 12 comprises a connecting sleeve 122, a threaded connecting segment 123, a helical coil unit 124 and a stopper 125. An elastic unit is a screw spring having creep resistance. The screw spring is extended like a long-pipe. One end of the screw spring is installed between the upper connecting segment 11 and the lower connecting segment 12, and the other extended end is exposed and extended from an opening part of a terminal end of the lower connecting segment 12 to form a plurality of stopper structures extended in a diametral direction and rotated. A hose 3 is installed at the lower connecting segment 12 and simultaneously a spring body is installed in the pipe of the hose 3 to eliminate stress deformation of the hose 3, protect the hose 3, and prevent it from being ruptured due to repetitive bending.</p> |
