Fire hose quick coupling anti-falling structure

Abstract

The utility model discloses a fire hose quick coupling anti -drop structure relates to pipeline connection technical field, including the clamp half ring, the clamp half ring is equipped with two groups, and the side of two groups the clamp half ring symmetry is provided with the screw hole, the inside of screw hole is inserted with bolt, and the side of bolt is equipped with the nut, the side fixedly connected with fixed plate of the clamp half ring, and the side swing of fixed plate is inserted with the rotating rod. The utility model discloses the fixed plate and the limiting plate are set up, when the nut is set up in the outside of bolt, through the setting of limiting plate, can realize the limiting locking of nut, effectively prevent its slack when receiving external force, strengthened the stability of fire pipeline connection, ensure the reliable operation of fire system, is equipped with the plug -in board and the plug -in rod, in the use process, through the mutual cooperation of plug -in board and plug -in rod, can adjust the interval between limiting plate and clamp half ring, to satisfy the limiting demand of different thickness nut.
