Fire hose connector

Abstract

The invention discloses a fire hose connector. The fire hose connector comprises an inner connecting piece and an outer connecting piece sleeving the inner connecting piece; the inner connecting piececomprises an inner plug inserted into a fire hose, a fixing table connected with the inner plug, a dismounting table connected with the fixing table, and an outer connector connected with the fixingtable; the outer connecting piece comprises a pressing part which sleeves the outer side of the fire hose and is matched with the inner plug, and a locking table which is connected with the pressing part and matched with the fixing table; and the fixing table and the locking table are matched, connected and locked in a threaded connection manner. The pressing part sleeves the outer side of the fire hose, and the inner plug is inserted into the inner side of the fire hose and is screwed through screw threads between the locking table and the fastening table, so that the connection of the fire hose is realized, uniform stress is realized when the fire hose is connected, leakage or even breakage of the fire hose at the connection location due to the uneven stress is avoided, and the guaranteeis improved for smooth testing of the fire hose.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire hose connector. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. The fire hose is lined with rubber, and the outer surface is wrapped with linen braid, or made of polymer materials such as polyurethane. The two ends of the fire hose Both have metal connectors that can be attached to another hose to extend the distance or to a nozzle to increase the liquid spray pressure. The performance of the fire hose directly affects the effectiveness of fire rescue. Therefore, it is necessary to test the performance of the fire hose when it leaves the factory. When it leaves the factory, the fire hose is equipped with metal joints. When testing the pressure bearing capacity of the fire hose, it is necessary to fix one end of the fire hose to the fire hose, and the other end must be se...

Problems solved by technology

The performance of the fire hose directly affects the effectiveness of fire rescue. Therefore, it is necessary to test the performance of the fire hose when it leaves the factory. When it leaves the factory, the fire hose is equipped with metal joints. When testing the pressure bearing capacity of the fire hose, it is necessary to fix one end of the fire hose to the fire hose, and the other end must be sealed and blocked to test the pressure bearing capacity. Therefore, it is necessary to design the corresponding fire hose With connection joints, and the existing connection joints generally use two compression tubes with flanges, one compression tube is sleeved on the outside of the fire hose, the other compression tube is inserted into the inside of the fire hose, and The fire hose is tightly connected between the two compression pipes by means of bolt connection, and when the connection is adopted in this way, when the bolts compress the two compression pipes, the bolts in all directions are connected When tightening at the same time, it is impossible to ensure that the stress conditions between the two compression tubes are the same everywhere, which will cause the circumferential force of the fire hose connection part of the compression tube during the compression of the fire hose. Unequal, when carrying out the pressure bearing test, it is easy to cause leakage or even breakage at the connection, and cannot well complete the test requirements for the pressure bearing capacity of the fire hose
