Embodiments of the present invention provide a fire hose described below with reference to fig. 1, including: the protective layer 20, the woven layer 30, the reinforced buffer layer 40 and the lining layer 10 are sequentially adhered from outside to inside.

In some embodiments, as shown in fig. 3, the outer wall of the protective layer 20 is provided with a plurality of ribs 21 extending along the axial direction of the fire hose, the ribs 21 and the protective layer 20 are integrally extruded, and the ribs 21 are uniformly distributed at intervals on the periphery of the protective layer 20.

In some embodiments, as shown in fig. 2, a plurality of T-shaped rings a are sequentially and uniformly bonded at intervals along the axial direction of the fire fighting hose on one side of the reinforcing buffer layer 40 close to the woven layer 30, a T-shaped ring B42 is clamped between every two adjacent T-shaped rings a41, a plurality of T-shaped rings B42 are uniformly spaced and arranged on one side of the reinforcing buffer layer 40 close to the lining layer 10, a first through hole 43 is formed on one side of the reinforcing buffer layer 40 where the T-shaped ring a41 and the T-shaped ring B42 are bonded, and a second through hole 44 is formed on one side of the reinforcing buffer layer 40 where the T-shaped ring B42 and the T-shaped ring a41 are bonded.

Due to the connection mode of the T-shaped ring A41 and the T-shaped ring B42 and the arrangement of the first through hole 43 and the second through hole 44, the reinforced buffer layer 40 has the functions of reinforcing the fire hose and buffering.

In some embodiments, the protective layer 20 is extruded from PVC or rubber or polyurethane.

In some embodiments, the woven layer 30 is woven from polyester filaments or flax filaments.

In some embodiments, the width of the rib 21 is 0.8 to 1.2mm, and the height thereof is 0.5 to 1 mm.

In some embodiments, the backing layer 10 and the reinforcing cushion 40 are extruded from PVC or rubber or polyurethane.

After glue is coated on the outer wall of the lining layer 10, the reinforcing buffer layer 40 is sleeved on the surface of the lining layer 10 in a penetrating mode, then one end of the lining layer 10 is fastened, high-temperature steam is injected into the other end of the lining layer 10, the lining layer 10 is expanded to enable the outer wall of the lining layer to be tightly attached to the inner wall of the reinforcing buffer layer 40, meanwhile, the glue is cured at high temperature through the steam, and the lining layer 10 and the reinforcing buffer layer 40 are bonded together after a certain period of time.

From this, it is known that the adhesion between layers of the fire hose is achieved by the inner layer expanding to adhere to the outer layer. However the utility model discloses increased on the basis of current double-deck hosepipe inoxidizing coating 20 and enhancement buffer layer 40 to inoxidizing coating 20, weaving layer 30 is that the silk thread is woven and is formed, does not have the gas tightness, if let in high temperature steam toward the weaving layer, can not make weaving layer 30 expand completely, and high temperature steam can pierce through the weaving layer on the contrary and can make inoxidizing coating 20 outwards expand, keeps away from weaving layer 30, and the unable inseparable bonding of both. Therefore, the utility model discloses in, the in-process of extrusion inoxidizing coating 20, the bead of inoxidizing coating is inwards, then wears to overlap weaving layer 30 back at the smooth outer wall coating glue of inoxidizing coating 20, lets in high temperature steam toward inoxidizing coating 20 and makes inoxidizing coating and weaving layer bonding, and rethread machine or manual work turn up the inoxidizing coating, make the inoxidizing coating outside in the weaving layer office. Then, the adhesive woven layer 30 and the protective layer 20 are inserted and sleeved on the lining layer 10 coated with the glue, and the inner lining is expanded by high-temperature steam,

the T-shaped ring A41 and the T-shaped ring B42 are arranged in the reinforcing buffer layer 40, and the clamping structure is integrally formed by molding materials.
