The traditional fire hose is lined with rubber and the outer surface is wrapped with linen fabric. With the development of technology, fire hoses are also made of polymer materials such as polyurethane, providing a more stable and high-temperature resistant range of use. Common fire hoses have metal joints at both ends, which can be connected to another hose to extend the distance or connected to a nozzle to increase the liquid spray pressure.

[0003] The existing patent document with the technical application number CN201620484859.9 provides an anti-static fire hose, which reduces the friction between the outer side of the pipe and the outside world by setting a wear-resistant ring, thereby reducing static electricity, and setting an anti-static layer of graphite fiber material to further reduce the generation of static electricity, but there are still the following disadvantages:

[0004] Although the existing anti-static fire hose is provided with a wear-resistant ring to support the outside of the pipe, due to the non-rigid material of the pipe, the wear-resistant rings cannot be supported and not in contact with the bottom surface. When in use, the area in the middle of the wear-resistant ring will still collapse due to gravity. Therefore, an anti-static fire hose is urgently needed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an anti-static fire hose to solve the problem that when the existing anti-static fire hose is in use, although the anti-static fire hose is provided with a wear-resistant ring to support the outside of the pipe, due to the non-rigid material of the pipe, the wear-resistant rings cannot be supported and not in contact with the bottom surface, etc., and the area in the middle of the wear-resistant ring will still collapse due to gravity when in use.

[0007] An auxiliary strip with a strip-shaped structure is also arranged in parallel on the outer tube wall. A steel wire runs through the interior of the auxiliary strip. The steel wire also runs through the interior of the support ring, and the steel wire is perpendicular to the support ring.

[0008] Preferably, the cross section of the auxiliary strip is a semicircular structure, the auxiliary strip is fixedly connected to the outer tube wall, and the radius of the auxiliary strip is consistent with the thickness of the support ring.

[0009] Preferably, six groups of auxiliary strips are provided, and the six groups of auxiliary strips are distributed parallel to each other on the outer surface of the outer tube wall, and the six groups of outer tube walls are distributed at equal distances.

[0012] Preferably, the protective layer is a mesh-like graphite fiber mesh.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can completely lift the device by the auxiliary strip on the inner pipe wall protruding from the outer pipe wall, avoiding direct contact and friction with the bottom surface and other objects, and avoiding the situation where the middle of the pipe collapses downward;
