Problems solved by technology

[0004] However, the traditional flame-retardant fire hoses including this invention are mostly rolled up in a coiled state during normal transportation or in the state of being rolled up when not in use, but some fastening mechanisms are not provided. It is easy to be scattered during the taking process, so that it needs to be re-coiled, which not only wastes time, but also brings inconvenience to people's use, and the connecting flange used for connection on the traditional hose is in an open state, and small insects or dust from the outside The debris is easy to enter, which will cause inconvenience to the normal use of the hose in the later stage, and even directly affect the fire fighting work, which has a great impact

Abstract

The invention relates to the technical field of fire-fighting hoses, in particular to a flame-retardant fire-fighting hose. Flame-retardant fire hose, including: a circular box, a nozzle, a hollow winding shaft and a hose, one side of the circular box is set as an opening, and the nozzle is fixed on the circular On the box body, the hollow winding shaft is rotatably installed on one side of the inner wall of the circular box body, and the water belt is wound on the hollow winding shaft; the cover is connected with the The circular box body is fixedly connected, the cover is adapted to the opening side of the circular box body; the concave frame is fixedly installed on the inner wall of the hollow winding shaft, and the One end of the hose passes through the inner wall of the hollow winding shaft and extends into the concave frame, and the hose is movably connected with the inner wall of the hollow winding shaft. The flame-retardant fire-fighting hose provided by the invention has the advantages of avoiding being scattered when taken, improving convenience, preventing foreign objects from entering, and reducing adverse effects.

Description

technical field [0001] The invention relates to the technical field of fire-fighting hoses, in particular to a flame-retardant fire-fighting hose. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. The traditional fire hose is lined with rubber and the outer surface is wrapped with flax braid. The advanced fire hose is made of polymer materials such as polyurethane. As a result, another hose can be connected to both ends to extend the distance or connected to a nozzle to increase the liquid spray pressure, and with the continuous development of technology, more and more high-end fire hoses have been developed, such as Flame retardant fire hose, etc. [0003] A flame-retardant fire hose is proposed in the prior art, the outer wall of the rubber inner tube is wrapped with a non-woven fabric layer, the outer wall of the non-woven fabric layer is wrapped with a soft steel wire layer, and the fir...
