Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire hose technology, and more specifically to a wear-resistant and weather-resistant fire hose. Background Technology
[0002] Fire hoses are flexible pipes used to transport fire-fighting water or other fire-fighting agents. They are widely used in various fire-fighting scenarios. They are usually made of high-strength fiber materials and have the characteristics of high pressure resistance, wear resistance, and corrosion resistance. They can withstand large water pressure and harsh working environments.
[0003] Existing fire hoses, such as "a lightweight wear-resistant fire hose" (application number: CN202322691453.0) and "an ultra-light wear-resistant fire hose" (application number: CN201821928905.5), have "raised points" and "wear-resistant blocks" respectively set on the surface of the hose to improve the wear resistance of the fire hose during use.
[0004] The aforementioned "protruding points" and "wear-resistant blocks" are generally made of soft materials (such as TPU, polyurethane, or rubber). Although they have good flexibility and impact resistance, their wear resistance is relatively poor under high-intensity friction or long-term use, which may cause the protrusions to wear out quickly. Alternatively, hard materials (such as nylon) may have excellent wear resistance, but they will significantly reduce the overall flexibility of the hose. In complex terrain or scenarios that require frequent bending, hard protrusions may make hose operation difficult or even increase the risk of breakage.
[0005] Therefore, there is an urgent need to develop a fire hose that integrates and optimizes flexibility, impact resistance, and abrasion resistance into its abrasion-resistant component. Utility Model Content
[0006] The purpose of this utility model is to provide a wear-resistant and weather-resistant fire hose in order to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] This utility model proposes a wear-resistant and weather-resistant fire hose, comprising:
[0009] Water hose body;
[0010] Multiple sets of protruding components are evenly fixed on the outside of the water hose body;
[0011] The protruding component includes a wear-resistant soft block fixed to the outside of the hose body;
[0012] The protruding component also includes a connecting cavity outside the wear-resistant soft block and a wear-resistant hard block that is fixed to the wear-resistant soft block by being inserted into the connecting cavity. The wear-resistant hard block does not contact the outside of the hose body.
[0013] The main body of the water hose is constructed from multiple layers of material from the inside out, with the outermost layer integrally formed with a wear-resistant soft block.
[0014] As a preferred technical solution of this utility model, the connecting cavity includes a groove and a slot provided on the outside of the wear-resistant soft block, and an annular groove provided in the slot;
[0015] The wear-resistant block includes a cap, a tube fixed on the cap, and a protruding ring fixed on the tube. The cap extends into the groove and is fixed in place, the tube extends into the slot and is fixed in place, and the protruding ring is fixed in the ring groove.
[0016] As a preferred technical solution of this utility model, the convex rings are provided in multiple sets and are evenly distributed outside the insertion tube, and the convex rings corresponding to the multiple sets are provided in multiple sets of annular grooves inside the slot.
[0017] As a preferred embodiment of this invention, the wear-resistant soft block is made of polyurethane, and the wear-resistant hard block is made of nylon.
[0018] As a preferred technical solution of this utility model, the water hose body includes a lining layer, a fabric reinforcement layer and a covering layer that are sequentially bonded and fixed from the inside to the outside, and a wear-resistant soft block is fixed to the outside of the covering layer.
[0019] As a preferred embodiment of this utility model, the lining layer and the covering layer are polyurethane layers, and the fabric reinforcement layer is a polyester woven layer.
[0020] The beneficial effects of this utility model are as follows:
[0021] By using cavities in the wear-resistant soft block to fit the external wear-resistant hard block, the wear-resistant soft block can maintain flexibility and impact resistance while the wear-resistant hard block provides a better wear-resistant surface. This ensures that the fire hose is suitable for field firefighting, industrial fire rescue, and urban fire rescue, and performs well in various scenarios. The integrated manufacturing of the wear-resistant soft block and the covering layer can improve the strength during use and reduce the possibility of detachment. Attached Figure Description

Detailed Implementation
[0025] like Figures 1-2 As shown, this utility model proposes: a wear-resistant and weather-resistant fire hose, comprising;
[0026] Water hose body 1;
[0027] Multiple sets of protruding components 2 are evenly fixed on the outside of the water hose body 1;
[0028] The protruding component 2 includes wear-resistant soft blocks 21 fixed on the outside of the hose body 1; by uniformly arranging multiple sets of wear-resistant soft blocks 21 on the outside of the hose body 1, during dragging and other operations, the overall surface of the hose body 1 can be raised above the ground, and the wear-resistant soft blocks 21 provide wear protection for the hose body 1.
[0029] The protruding component 2 also includes a connecting cavity 22 located outside the wear-resistant soft block 21 and a wear-resistant hard block 23 that is fixed to the wear-resistant soft block 21 by being inserted into the connecting cavity 22. The wear-resistant hard block 23 does not contact the outside of the hose body 1.
[0030] By setting a connecting cavity 22 on the outer side of the wear-resistant soft block 21 away from the main body of the hose 1, the external wear-resistant hard block 23 is attached through this connecting cavity 22. The attachment position can be connected and fixed with strong adhesive or the like. In this way, the wear-resistant soft block 21 can provide a better wear-resistant surface with the wear-resistant hard block 23 while ensuring flexibility and impact resistance. It is suitable for harsh environments with high wear and high impact (such as field fire fighting and industrial fire rescue), and can also meet the needs of scenarios with high flexibility requirements (such as urban fire rescue) to a certain extent.
[0031] The water hose body 1 is integrally formed by multiple layers of material from the inside to the outside, and its outermost layer is integrally formed with the wear-resistant soft block 21, which makes it easy to manufacture the wear-resistant soft block 21.
[0032] Among them, the wear-resistant soft block 21 is made of polyurethane, and the wear-resistant hard block 23 is made of nylon;
[0033] The main body of the water hose 1 includes a lining layer 11, a fabric reinforcement layer 12 and a cover layer 13 that are sequentially attached and fixed from the inside to the outside. The cover layer 13 is fixed to the outside of the wear-resistant soft block 21.
[0034] The lining layer 11 and the cover layer 13 are polyurethane layers, and the fabric reinforcement layer 12 is a polyester woven layer. The polyurethane material provides good weather resistance, abrasion resistance, tear resistance and elasticity.
[0035] When the cover layer 13 is manufactured, since both the wear-resistant soft block 21 and the cover layer 13 can be made of polyurethane material, they can be molded into one piece by injection molding or extrusion molding process; or they can be directly bonded to connect the wear-resistant soft block 21 and the cover layer 13, but the strength is low and they are easy to fall off.
[0036] The specific structure of the connecting cavity 22 and the wear-resistant block 23 is shown below:
[0037] The cavity 22 includes a groove 221 and a slot 222 located on the outside of the wear-resistant soft block 21, and an annular groove 223 located in the slot 222; the groove 221 and the slot 222 are provided at one end away from the wear-resistant soft block 21, and the groove 221 is connected to surround the outside of the slot 222, and the annular groove 223 is provided in the slot 222;
[0038] The wear-resistant block 23 includes a cover 231, an insert 232 fixed on the cover 231, and a protruding ring 233 fixed on the insert 232; using an arc-shaped plate (i.e., cover 231) with an arc-shaped protrusion away from the water hose body 1, an insert 232 is integrally fixed on the side of the cover 231 facing the water hose body 1, and a protruding ring 233 is integrally fixed on the outside of the insert 232;
[0039] The cap 231 extends into the groove 221 and is fixed in place, the tube 232 extends into the slot 222 and is fixed in place, and the protruding ring 233 is fixed in the annular groove 223. By applying glue to the surfaces of the tube 232, the protruding ring 233, and the outer surface of the cap 231 that is fixed in the groove 221, and then inserting the tube 232 into the slot 222, the protruding ring 233 is fixed in the annular groove 223 during this process until the cap 231 is fixed in the groove 221, thus completing the connection and fixation. The operation is simple and the stability is good.
[0040] Among them, multiple sets of convex rings 233 are provided and evenly distributed outside the insertion tube 232, and multiple sets of annular grooves 223 are provided in the slot 222 corresponding to the multiple sets of convex rings 233; such as Figure 2 Three sets of protruding rings 233 and slots 222 are set. After the insertion tube 232 is inserted into the slot 222, the three sets of protruding rings fit into the slot 222 one by one to lock it in place, thereby further improving the connection strength.
