Abstract

PURPOSE: A fire hose coupling is provided to extinguish the fire more efficiently and safely without degrading the conventional operation ability. CONSTITUTION: A fire hose coupling comprises a male coupling unit(20) and a female coupling unit(10). The male coupling unit includes a circular projection part on one side and with a female connection part on the other side; a male coupling body installed respectively with sliding-moving cylinders between the circular projection part and a male hose connection part; a pressure ring capable of sliding in the sliding-moving cylinder; and a female coupling body installed with a female coupling structure of the female coupling on one side and with a female hose connection part on the other side. The section of the male hose connection part of the circular projection part is formed with a hanging-brake locking groove forming a slope and the female structure is installed with a projection contacting the slope.

Description

technical field [0001] The invention relates to a joint fitting of a fire hose, in particular to a joint fitting of a fire hose equipped with a fall-off prevention mechanism, and the fall prevention mechanism is used to avoid the danger caused by the fire hose falling off. Background technique [0002] When the fire brigade is carrying out fire extinguishing activities, it is necessary to extend the fire hose from the fire truck to the fire point to reliably transport the fire extinguishing agent. [0003] The fire hose and the discharge outlet of the fire engine, the fire hose and the water discharge nozzle, and the fire hose are connected with each other by joint fittings. Pressurized water or foam is sent from the fire truck to the discharge nozzle through them, and then the water or foam is released for fire extinguishing and the like. [0004] There are plug-in type, screw type, and twist type among the joints sold in Japan. Plug-in Machino-style couplings are used in...
