The invention discloses a fire hose joint specialized for fire protection. The fire hose joint comprises a fire hose body. A fireproof layer is arranged at the bottom end of the fire hose body. A fire hose is arranged at the bottom end of the fireproof layer. A hoop is arranged on one side of the fire hose. Grapnels are arranged on one side of hoop. A first hose joint body is arranged in the hoop. A washer is arranged between the hoop and the first hose joint body. Straight rod grooves are formed in the periphery of the first hose joint body. A second hose joint body is arranged on one side of the first hose joint body. Straight rods are arranged on the periphery of the second hose joint body. Grapnel grooves are formed in one side of the second hose joint body. According to the fire hose joint, the hoop is arranged to be buckled to the exteriors of the hose joint bodies, the grapnels are embedded into the grapnel grooves, and the washer and reinforcing ribs are arranged, so that the leakproofness is good, and the buckled fire joint is high in strength, not prone to being broken and capable of bearing impact of high water supply pressure; and the fire hose joint is reasonable in design, simple in structure and convenient to use, so that the practicability is effectively improved.
Description
technical field [0001] The invention relates to a fire-fighting hose joint, in particular to a special-purpose fire-fighting hose joint, which belongs to the field of fire-fighting equipment. Background technique [0002] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. A traditional fire hose is lined with rubber and wrapped with a linen braid on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. The fire joints are mainly used for the connection between water belts, fire hydrants and water guns, etc., to carry out fire extinguishing work of transporting water or mixed liquids. The fire joints are usually composed of braided layers and inner The lining is soft and can withstand high-pressure water flow. Fire-fighting joints are generally provided at both ends of the hose, and the two hoses can be connected together through the joints. Since the fire fighting time is very urgent, it is h...
