Abstract

The present invention relates to the technical field of fire-fighting equipment, specifically a fire hose joint for firefighting purposes, comprising a first connecting head, wherein one side of the first connecting head is provided with a first placement groove, wherein a first stop block and a first compression block are fixed inside the first placement groove, and a first grip is fixed on the other side of the first connecting head. The central part of the first grip is fixed with a card block through the first connecting block. The present invention provides a first stop block, a first compression block, a second stop block, and a second compression block. When connecting, only the second compression block is inserted into the gap between the two first compression blocks in the first placement groove, and then the first grip and the second grip are rotated in the opposite direction to make the inclined surfaces of the first compression block and the second compression block conform to each other. Squeeze until the first squeezing block contacts the second blocking block, and the second squeezing block contacts the first blocking block, The connection between the first connector and the second connector can be quickly completed, with simple and convenient operation, which helps to improve the efficiency of firefighting operations.

Description

Fire hose joint special for fire fighting Technical Field The invention relates to the technical field of fire-fighting products, in particular to a fire hose connector special for fire fighting. Background The fire hose is used as key equipment for conveying water or foam mixed liquid in fire-fighting operation, and the reliability and convenience of connection of the fire hose are directly related to the efficiency and safety of fire suppression. In fire practice, firefighters need to rapidly spread the hose and connect to fight for valuable rescue time. The fire hose joint is used as a connecting part between water hoses or between the water hoses and fire-fighting equipment (such as a fire hydrant, a water separator and a water gun), is an indispensable important component part in a water hose line, and the rationality of the structural design plays a decisive role in the stable operation of the whole fire-fighting water supply system. At present, the traditional fire hose connector widely used in fire-fighting operation generally adopts a butt-clamp type or threaded type connecting structure, when in connection, a firefighter holds the main body parts of the two connectors respectively, the clamping part of one connector is aligned to the clamping groove or the clamping claw of the other connector, and then the clamping part and the clamping claw are clamped in place through relative rotation or pressing, so that the connection of a hose line is realized, and the quick assembly between hose is completed.
