HIGH-PRESSURE LINE THROUGH APPARATUS

摘要

PURPOSE: A high-pressure line through apparatus is provided to enable performing a line through work in a rapid and convenient manner by using a high air pressure. CONSTITUTION: A solid cylindrical body(10) is connected with a high-pressure air hose. A sealing support unit(20) has a fixing ring(21) fixedly coupled to the leading edge periphery of the cylindrical body(10) and a traveling ring(22) coupled movably. A compression support unit(30) has a pair of compression assisting rings(31) movably coupled to one side of the outer periphery of the cylindrical body(10) and a pair of semi-cyclic compressing mounts(32) movable in the radial direction of the cylindrical body(10) between the compression assisting rings(31). A fixed handle unit(40) is screwed to the other side of the outer periphery of the cylindrical body(10) and moves along the longitudinal direction of the cylindrical body(10). Compressing rings(23,34) compress the compress assisting rings(31) and the traveling rings(22) from sides by movement of the fixed handle unit(40).
