Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, in particular to an indicating fire hose. Background Art

[0002] A fire hose is a flexible pipe used to deliver high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses are lined with rubber and covered with a braided outer layer. Modern fire hoses are made of polymers such as polyurethane. Both ends of a fire hose have metal connectors that allow it to be connected to another hose for extended reach or to a nozzle for increased pressure.

[0003] Generally, fire hoses with indicator types are basically provided with fluorescent indicator arrows on the outer layer of the hose so that in dim conditions, the fluorescent indicator arrows can be used for indication, so that fire escape can be used. However, in the fire scene, the fluorescent light may be covered with dust due to friction and other conditions, which is difficult to wipe off, resulting in the fluorescent effect not being able to be well exerted the next time it is used. Utility Model Content

[0004] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the description and other drawings.

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an indicating fire hose to solve the existing problems.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: an indicating fire hose, comprising a hose body, the outer wall of which is provided with a water-blocking cloth layer, the outer wall of which is provided with a flame-retardant EVA hot-melt adhesive layer, the outer wall of which is provided with a wear-resistant layer, the surface of which is provided with a plurality of indicating grooves, a fluorescent indicating layer is provided in the indicating groove, and the fluorescent indicating layer includes a plurality of first fluorescent layers.

[0007] In some embodiments, the first fluorescent layer has no less than four layers.

[0008] In some embodiments, an adhesive layer is disposed at the bottom of the first fluorescent layer.

[0009] In some embodiments, a second fluorescent layer is provided between the wear-resistant layer and the flame-retardant EVA hot melt adhesive layer.

[0010] In some embodiments, the edge of the first fluorescent layer is connected to the indicator groove through a plurality of yarns.

[0011] In some embodiments, the wear-resistant layer is woven from nylon.

[0012] In some embodiments, the wear-resistant layer has a thickness of 4 mm.

[0013] By adopting the above-mentioned technical solution, the beneficial effect of the utility model is as follows: when a large amount of dust accumulates on the surface of the fire hose after use and it is difficult to clean, the outermost fluorescent indicator layer can be torn off one layer in the indicator groove to leak out the next layer and continue to use it. This can avoid the situation where the dust cannot be cleaned after friction and the indication cannot be continued. Then, the water-blocking cloth layer can effectively prevent internal water leakage, and the flame-retardant EVA hot-melt adhesive layer can improve the flame-retardant effect.

[0032] According to some embodiments of the present invention, optionally, an adhesive layer 44 is provided at the bottom of the first fluorescent layer 43 to prevent the fluorescent layer from falling off during use.

[0033] According to some embodiments of the present invention, a second fluorescent layer 6 is optionally provided between the wear-resistant layer 4 and the flame-retardant EVA hot-melt adhesive layer 3. When the first fluorescent layer 43 of the indicator slot 41 is completely torn off, the second fluorescent layer 6 is exposed and continued use is possible. The second fluorescent layer 6 is woven from nylon and a fluorescent agent to increase wear resistance.

[0034] According to some embodiments of the present invention, the edge of the first fluorescent layer 43 is optionally connected to the indicator groove 41 by a plurality of yarns 45. The adhesive layer 44 can be kept from being torn off during dragging, and when it needs to be replaced, the yarn 45 connected can be cut with a knife and the top layer can be torn off.
