DETAILED DESCRIPTION
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, a fire hose comprises a belt body and a connector, the belt body comprises an innermost waterproof rubber layer 11, an inner flexible steel mesh layer 12 fixedly sleeved on the outside of the waterproof rubber layer 11, an inner wear-resistant layer 13 fixed on the outside of the inner flexible steel mesh layer 12, an outer flexible steel mesh layer 14 fixedly sleeved on the outside of the inner wear-resistant layer 13 and an outer wear-resistant layer 15 fixed on the outside of the outer flexible steel mesh layer 14, along the length direction of the belt body, a plurality of wear-resistant ridges 151 are arranged on the outside of the outer wear-resistant layer 15, and wear-resistant ridges 152 are arranged between adjacent wear-resistant ridges 151.
[0019] Along the length direction of the belt body, by arranging wear-resistant convex strip 151 and wear-resistant convex strip 2 152 on the outside of the outer wear-resistant layer 15, the wear resistance of the belt body can be effectively enhanced; by arranging the inner flexible steel wire mesh layer 12, the inner wear-resistant layer 13 and the outer flexible steel wire mesh layer 14 between the waterproof rubber layer 11 and the outer wear-resistant layer 15, the compressive strength and flexibility of the belt body can be guaranteed and the wear resistance of the belt body can be further enhanced; the utility model can effectively enhance the wear resistance of the fire hose, avoid the problem of cracking and leakage of the fire hose due to wear, and extend the service life of the fire hose.
