PIPE CONNECTOR WITH LOOSE PREVENTION FUNCTION

摘要

PURPOSE: A pipe connector with an anti-loosening function is provided to stably fix pipes without movement by employing fixing elements installed in a connection housing. CONSTITUTION: A pipe connector with an anti-loosening function comprises a connection housing(10), a plurality of screw holes(20), and a plurality of fixing elements. The connection housing has a pipe insertion hole(11), packing insertion recesses(12) which are depressed on both sides of the pipe insertion hole, and a pair of U-packings(13) which are inserted in the packing insertion recesses. The screw holes are radially bored on both sides of the connection housing from the interior to the exterior. The fixing elements fix pipes inserted to both sides of the pipe insertion hole. The U-packings have a pressure acting groove(13a) and an inner peripheral part(13b) which contacts the outer peripheral surface of a pipe when the pressure acting groove is opened by pressure. A tightening spring(15) is inserted in the pressure acting groove to tighten the inner peripheral part.
