Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-7 , the present utility model provides the following technical solutions: A fire hose with anti-tensile properties, including a water hose body 1 and a fire fighting connector 2. The end of the water hose body 1 is connected with a fire fighting connector 2. The water hose body 1 is made of polyurethane material. The fire hose made of polyurethane material has good high-pressure resistance and wear resistance. It has high strength and remarkable anti-tensile ability. Usually, the tensile strength requirement of the fire hose is not less than 15 MPa, and the polyurethane material can meet or exceed this standard;

[0026] The surface of the water hose body 1 is connected with a strap 3. The upper and lower ends of the strap 3 are respectively connected with a first connecting strip 4 and a second connecting strip 5. The other end of the first connecting strip 4 is connected with a docking plate 6, and the other end of the second connecting strip 5 is connected with a docking seat 7. The bottom end of the docking plate 6 is connected with a clamping block 8. The inner wall of the opening of the clamping block 8 is connected with a telescopic spring 9, and the other end of the telescopic spring 9 is connected with a buckle 10.

[0027] Preferably: Both the first connecting strip 4 and the second connecting strip 5 are made of nylon material, and both the docking plate 6 and the docking seat 7 are made of PVC material.

[0028] During specific use, the flexible first connecting strip 4 and second connecting strip 5 facilitate adaptation to various sizes.

[0029] Preferably: The surface size of the clamping block 8 is adapted to the size of the buckling part of the docking seat 7, and the docking plate 6 is connected with the docking seat 7 through the clamping block 8.

[0030] During specific use, by docking the clamping block 8 with the docking seat 7, it is convenient to limit and fix the fire hose.

[0031] Preferably: One side surface of the clamping block 8 is arc-shaped, and the clamping block 8 and the telescopic spring 9 form an elastic telescopic structure.

[0032] During specific use, by controlling the use of the clamping block 8, it is convenient to bind or use the hose body 1.

[0033] Preferably: A binding ring 11 is connected to the surface of the joint between the hose body 1 and the fire fighting connector 2, and a sealing ring 12 is connected to the inner wall of the binding ring 11. The sealing ring 12 is made of rubber.

[0034] During specific use, by using the sealing ring 12, the phenomenon of water seepage and leakage at the connection of the fire hose is avoided, ensuring normal use.

[0035] Preferably: A fastening bolt 13 is connected through the joint of the binding ring 11, and a nut 14 is threadedly connected to the bottom end of the fastening bolt 13.

[0036] During specific use, by connecting the fastening bolt 13 and the nut 14, it is convenient to install and fix the binding ring 11.

[0037] The working principle and its advantages during specific use are as follows: First, tie the strap 3 around the surface of the hose body 1, then dock the docking plates 6 and the docking seats 7 at the ends of the first connecting strip 4 and the second connecting strip 5, driving the clamping block 8 on the bottom surface of the docking plate 6 to dock with the opening on the surface of the docking seat 7, and at the same time driving the buckle 10 to squeeze the telescopic spring 9, so that the buckle 10 is fitted into the opening on one side of the docking seat 7. If in use, press the buckle 10 inward to quickly tie the hose body 1, making it more convenient to use. In addition, by installing the binding ring 11 at the connection between the hose body 1 and the fire fighting connector 2, the use of the sealing ring 12 avoids the phenomenon of water seepage and leakage at the connection between the hose body 1 and the fire fighting connector 2. Then, fix the binding ring 11 with the fastening bolt 13 and the nut 14, ensuring the sealing performance of the fire hose during use.
