The Coupling structure with fastening pipe and coupling screw of Coupling tube and coupling screw structure

摘要

The present invention is to block the water in the water pipe exposed to the ground with a valve configured in the ground, and the water in the ground can be drained to improve the pressurization efficiency of the inner pipe of the binding pipe of the floating water supply with a replacement function to prevent freezing. The present invention relates to a sealing coupling structure of a binding tube for floating water supply having a replacement function. The upper outer circumferential surface of the outer tube body is provided with a pressing body having one or more protruding members having a screw groove, and a pressing member having a piece coupling hole to correspond to the upper side of the protruding member, the pressing body On the upper center of the center, a dome-shaped floating water supply support connection hole is provided, and on its outer circumferential surface, a binding plate is provided with a support base for pressing the inner pipe. Or it is provided to be fastened by a sealing coupling means having a piece-shaped fastener. The present invention has the advantage of obtaining a solidity of the solid fastening structure by having a binding plate fixedly installed by a pressing member fixedly installed by a fastener by engaging with a protruding member having a plurality of screw grooves on the upper outer circumferential surface of the outer sheath. .
