Abstract

The utility model discloses a novel fire coupling which comprises a male coupling, a female coupling, elastic sliding paw which moves radially, a sealing ring, a pushing ring which moves axially and amating ring. The mating ring is positioned in the groove at the end of the female coupling. The elastic sliding paw is positioned in a chamber which is formed by the female coupling, the male coupling and the matching ring. The matching ring is provided with two coaxial cylindrical extension arms which are integrated. The axes of the cylindrical extension arms pass through the circle center of the matching ring. The end of the extension arm of each matching ring is movably connected with a sliding sleeve which rotates along the axis of the extension arm. As the structure provided by the utility model is adopted, The fire coupling provided by the utility model has an advantage that the end of the fire coupling connected with the water pipe can rotate randomly without knotting and can be conveniently connected with the other end of coupling on a fire fighting truck.

Description

A kind of novel Fire coupling

Technical field

The utility model relates to fire-fighting equipment, especially relates to the novel Fire coupling that connects fire-extinguisher water hose in a kind of water system.

Background technique

The Fire coupling that connects fire-extinguisher water hose in the existing waterworks for firefighting, comprise female coupling, male coupling, seal ring, the sliding pawl of elasticity, pushing circle and adapter ring, has the groove that seal ring is installed in the female coupling, adapter ring is a flange arrangement, the cavity at the interval that the sliding pawl of elasticity forms when being positioned at female coupling, male coupling and adapter ring assembling.Such structure fireman is when the water band docks with the fire-fighting truck interface in tow, because interface can not rotate, the water band is tied a knot easily, it is unimpeded to influence current, again because generic interface is a cylindrical body, the fire fighter is difficult for promptly interface, just be difficult to fire-fighting truck on interface end dock rapidly, cause the delay on the fire-fighting fire extinguishing setup time easily.

The model utility content

Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of rational in infrastructure, and the water band is not tied a knot the novel Fire coupling that Fire coupling can dock with fire-fighting truck fast when being convenient to the fire fighter simultaneously and putting out a fire.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of novel Fire coupling, comprise male coupling, female coupling, the sliding pawl of the elasticity of radial motion, seal ring, the pushing circle and the adapter ring of axial motion, seal ring is positioned at the groove of female coupling end, the sliding pawl of elasticity is positioned at female coupling, in the cavity at the interval that male coupling and adapter ring form, described adapter ring is provided with the cylindric cantilever arm of two same axis that form one, the axis of described cylindric cantilever arm is by the adapter ring center of circle, and the end of the cantilever arm of each adapter ring is connected with along the rotating sliding sleeve of described cantilever arm axis.

The sliding pawl of described elasticity is three, is distributed on the same circumference.

The utility model adopts such structure, Fire coupling has cantilever arm, form rotating moment ears between sliding sleeve and cantilever arm, both hands were held an end of the ears interface that connects the water band when the fire fighter put out a fire, arbitrarily the rotation of water band is not tied a knot, can be light, exactly it is connected rapidly with the interface of fire-fighting truck one end.Thereby saved the connect hours of Fire coupling to greatest extent, accelerated the fire-fighting fire extinguishing setup time, alleviated fire fighter's muscle power, and can dismantle interface from fire-fighting truck quickly and easily after the fire extinguishing.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;

Fig. 1 is the utility model structural representation;

In Fig. 1,1, female coupling; 2, seal ring; 3, the sliding pawl of elasticity; 4, pushing circle; 5, male coupling; 6, adapter ring; 7, sliding sleeve.

Embodiment

A kind of as shown in Figure 1 novel Fire coupling comprises the sliding pawl 3 of elasticity, the seal ring 2 of male coupling 5, female coupling 1, radial motion, the pushing circle 4 and the adapter ring 6 of axial motion, and seal ring 2 is positioned at the groove of female coupling 1 end, and seal ring 2 can be rubber seal.The sliding pawl 3 of elasticity is positioned at the cavity at the interval of female coupling 1, male coupling 5 and adapter ring 6 formation, and the sliding pawl 3 of elasticity is three, is distributed on the same circumference.Male coupling 5 is inserted in the female coupling 1, and the female coupling 1 interior sliding pawl 3 of elasticity blocks male coupling 5, realizes connecting fast, during dismounting, only pushing circle 4 need be pushed and can take out male coupling 5, has both connected steadily, and is safe and reliable again.Adapter ring 6 is provided with the cylindric cantilever arm of two same axis that form one, the axis of cylindric cantilever arm is by adapter ring 6 centers of circle, the end of each cantilever arm is connected with along the rotating sliding sleeve 7 of cantilever arm axis, when putting out a fire, the fire fighter holds sliding sleeve 7, Fire coupling one end that is connected with the water band can rotate arbitrarily, all can be easily with fire-fighting truck on the other end of interface be connected rapidly and accurately.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
