Abstract

The present invention relates to a fire hose having an untwisting structure whose coupling absorbs a twist of a hose in order to facilitate untwisting of the hose in the initial supply of water before a nozzle is opened, thereby preventing an accident. The fire hose of the present invention comprises: a woven hose formed by weaving a coating layer on the inner surface; a male untwisting coupling joined to one end of the woven hose and disposed to be connected to a nozzle or a connecting fire hose; a female untwisting coupling joined to the other end of the woven hose and disposed to be connected to a fire truck or a connecting fire hose; and an untwisting bearing ball disposed on the male untwisting coupling to rotate and absorb untwisting in an initial process of water supply by the fire hose. Accordingly, the coupling absorbs twists of the hose in order to facilitate untwisting in the initial supply of water before a nozzle is opened, thereby preventing an accident.

이하, 본 발명의 적용실시에 따른 작용효과에 대하여 설명하면 다음과 같다.Hereinafter, the effects of the application of the present invention will be described as follows.

즉, 본 발명은 소방호스에 있어서, 직조형성되면 내부가 코팅형성되어 구비되는 직조호스와 상기 직조호스의 일단에 결합되어 관창 또는 연결대상 소방호스와 연결될 수 있게 구비되는 수꼬임풀림커플링, 상기 직조호스의 다른 일단에 결합되어 소방차 또는 연결대상 소방호스와 연결될 수 있게 구비되는 암꼬임풀림커플링 및 수꼬임풀림커플링에 소방호스의 초기 급수과정에 꼬임풀림을 회전흡수할 수 있게 구비되는 꼬임풀림베어링으로 구성한 본 발명을 적용하여 실시하게 되면, 관창을 개방하기전 초기 급수에 있어 꼬임의 풀림이 원활하게 호스의 꼬임을 커플링에서 흡수하여 안전사고를 방지되는 것이다.That is, in the fire hose, the present invention relates to a woven hose having a coating formed therein when woven, and an untwisted coupling provided to be connected to a pipe window or a connection target fire hose by being coupled to one end of the woven hose, the It is coupled to the other end of the woven hose and is provided to rotate and absorb the untwisting in the initial water supply process of the fire hose to the female untwisted coupling and the male untwisted coupling, which are provided to be connected to a fire engine or a fire hose to be connected. When the present invention composed of a loosening bearing is applied and implemented, the untwisting of the twist in the initial water supply before opening the pipe window smoothly absorbs the twist of the hose from the coupling, thereby preventing a safety accident.

또한, 상기 (암/수)꼬임풀림커플링을 (암/수)나사체결몸체(100)와 호스결속몸체(200), 보조연결몸체(300)로 구비하고, 상기 호스결속몸체(200)가 나사체결몸체(100)와 보조연결몸체(300) 내부로 들어가며 (암/수)꼬임풀림커플링을 굴곡이없는 원통형으로 조립형성하여 실시하게 되면 호스의 물주입시 꼬임현상이 발생할 때 꼬임풀림이 원통내부에서 이루지게 되어 (암/수)꼬임풀림커플링을 파지하는 손에 별도의 회전력이 전달되지 않아 풀림에 손이 함께 돌아가는 사고를 방지하는 것이다.In addition, the (female/male) untwisted coupling is provided with a (female/male) screw fastening body 100, a hose binding body 200, and an auxiliary connecting body 300, and the hose binding body 200 is When the (female/male) untwist coupling is assembled into a cylindrical shape without bending while entering the screw fastening body 100 and the auxiliary connection body 300, untwisting occurs when the hose is kinked when water is injected. This is done internally to prevent an accident in which the hand rotates together when unwinding because a separate rotational force is not transmitted to the hand holding the (female/male) untwisted coupling.

또한, (암/수)나사체결몸체와 호스결속몸체(200), 보조연결몸체(300) 각각 연결부 사이에 제1오링(510) 제2오링(520) 제3오링(530)을 구비하여 내부 물의 유출 및 외부 물의 유입을 방지하는 것이다.In addition, a first O-ring 510, a second O-ring 520, and a third O-ring 530 are provided between the (female/male) screw coupling body, the hose coupling body 200, and the auxiliary connection body 300, respectively. It is to prevent the outflow of water and the inflow of external water.

또한, 상기 베어링삽입턱(122)으로 인해 형성된 베어링삽입공간(400)에 꼬임풀림베어링을 삽입하고, 방지링걸림턱(123)과 방지링끼움홈(211)에 이탈방지링(600)을 구비하여 실시하게 되면 꼬임풀림베어링과 이탈방지링(600)이 호스결속몸체(200)가 장치 내부에 삽입시 걸리게 되어 호스결속몸체(200)의 삽입결속이 이루어지는 것이다.In addition, the untwisted bearing is inserted into the bearing insertion space 400 formed by the bearing insertion jaw 122, and the anti-separation ring 600 is provided in the prevention ring engagement projection 123 and the prevention ring fitting groove 211. When this is carried out, the untwisted bearing and the separation prevention ring 600 are caught when the hose binding body 200 is inserted into the device, so that the insertion and binding of the hose binding body 200 is made.

이때, 상기 호스결속몸체(200)의 외부면이 꼬임풀림베어링의 볼삽입공(731)의 입구를 막아 베어링볼(710)의 이탈을 방지하는 것이다.At this time, the outer surface of the hose binding body 200 blocks the inlet of the ball insertion hole 731 of the untwisted bearing to prevent separation of the bearing ball 710 .

또한, 상기 수압확인공(800)을 구비하여 실시하게 되면 암꼬임커플링(20)과 수꼬임커플링(30)을 분리할 때 내부에 수압이 걸려있는 것을 시각적으로 확인할 수 있어서 수압이 제거된후 이를 분리하여 안전한 분리가 이루어지는 것이다.In addition, when the water pressure check hole 800 is provided, it can be visually confirmed that water pressure is applied inside when the female twisted coupling 20 and the male twisted coupling 30 are separated, so that the water pressure is removed. After that, it is separated and safe separation is achieved.
