Preferably, the fluorescent strip is a glue strip coated with fluorescent powder.

Preferably, the supporting framework is of a knitted rubber hose structure.

Preferably, the wear-resistant rubber convex body and the wear-resistant rubber layer are both made of NBR material.

Preferably, the fluorescent strip is arrow-shaped.

Preferably, the distance between every two fluorescent bars is 0.3-0.5 m.

Preferably, the oil-resistant low-temperature-resistant layer is a coating mainly made of nitrile rubber.

The utility model has the advantages of:

1. eight wear-resistant rubber convex body bulges are uniformly arranged on the outer surface of the water hose, so that a fire fighter can drag the water hose repeatedly during operation, and the wear-resistant rubber convex body bulges can rub the ground, so that the friction between the water hose and the ground is reduced, and the service life of the water hose is prolonged;

2. two steel bar ropes are arranged inside the water pipe belt, so that the water pipe can be protected to a great extent when the water pressure is high, and the structural stability of the water pipe belt is improved;

3. the evenly distributed phosphor strip of surface, the fire fighter of being convenient for operate when the concentration is lower with the discernment of being convenient for when sparse crowd, prevent to take stumbling because of the water pipe and influence evacuation efficiency, improve security and practicality.

Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1 to 4, the fire hose provided by this embodiment includes a supporting frame 102 and a wear-resistant rubber layer 101 fixed on an outer side surface of the supporting frame 102, the structural strength and corrosion resistance of the water pipe belt are increased, eight wear-resistant rubber protrusions 2 uniformly distributed are fixed on an outer side surface of the wear-resistant rubber layer 101, the wear-resistant rubber protrusions 2 are of a semi-cylindrical structure, a plurality of wear-resistant rubber protrusions 2 are parallel to the supporting frame 102, the wear-resistant rubber protrusions 2 rub against the ground, so as to reduce friction between the water pipe belt and the ground, increase the service life of the water pipe belt, an oil-resistant and low-temperature-resistant layer 103 is fixed on an inner side surface of the supporting frame 102, a plurality of reinforcing steel ropes 4 are fixed between the supporting frame 102 and the oil-resistant and low-temperature-resistant layer 103, thereby facilitating water pipe dragging, increasing the structural stability of the water pipe belt, and, the fixed phosphor strip 3 that is provided with a plurality of evenly distributed on the recess 201 is convenient for the fire fighter to operate when the concentration is lower, and is convenient for discern when sparse crowd.

In this embodiment, as shown in fig. 1 and 3, the fluorescent strip 3 is a glue strip coated with fluorescent powder, and has a stable structure, so as to prevent abrasion during dragging.
