Embodiment
Be described in detail the technical solution of the utility model below in conjunction with accompanying drawing in order further to explain.As shown in Figures 1 to 4, a kind of fire hose coupling, comprise interface body 2 and be plugged in the packing holder 1 in interface body 2, the two ends of packing holder 1 are made as respectively first end 11 and the second end 12, and interface body 2 is set on first end 11, in an embodiment, the outer tube wall of described first end 11 is provided with annular slot 112, in annular slot 112, be provided with back-up ring 8, first end 11 inserts after interface body 2, by back-up ring 8, interface body 2 is fastened on packing holder 1.The interface body 2 connecting by back-up ring 8 can be rotated relatively with packing holder 1, connects after fire-extinguisher water hose like this at packing holder 1, and the fire-extinguisher water hose after curling can be exceptionally straight under the pressure-acting of water; Now packing holder 1 is understood relative rotation to adapt to fire-extinguisher water hose angle of swing with interface body 2, thereby it is reliable to ensure that this fire hose coupling connects, and is difficult for being damaged.Be provided with first ring connected in star 121 at the outer tube wall of the second end 12, in described first ring connected in star 121, be arranged with sealing gasket 3, sealing gasket 3 is selected annular seal rubber pad.
Preferably, the axial length of sealing gasket 3 is less than the groove width of first ring connected in star 121, and sealing gasket 3 slightly exceeds the opening of first ring connected in star 121.Sealing gasket 3 is inserted in after first ring connected in star 121 like this, only occupy a part of space of first ring connected in star 121, the remaining segment space of first ring connected in star 121 is with 5 embeddings and water band 5 is fixed on packing holder 1 in order to supply water, avoid water band 5 move and depart from packing holder 1 along the axial direction of packing holder 1, cause water band 5 to come off.In an embodiment, sealing gasket 3 is resisted against on the cell wall of first ring connected in star 121 near the second end 12 ends, when water band 5 is inserted in after packing holder 1, by the fixing water band 5 of clip 6, water band 5 is partially submerged into first ring connected in star 121 to realize closely cooperating of water band 5 and packing holder 1 under the effect of clip, water band 5 can produce certain pressure to sealing gasket 3 simultaneously, between the outer tube wall of sealing gasket 3 and packing holder 1, all can produce interaction force between sealing gasket 3 and the inwall of water band 5, play seal action.In the time that the hydraulic pressure in water band 5 is too large, high pressure water enters from the gap between water band 5 and packing holder 1 outer tube wall and the side of sealing gasket 3 is produced to active force, promoting sealing gasket 3 moves until the inwall at water band 5 is supported in the another side of sealing gasket 3 to clip 6 directions, sealing gasket 3 is stressed and expand subsequently, further plays sealing effect.Certainly, also sealing gasket 3 can be resisted against to another sidewall of first ring connected in star 121, if now the side of sealing gasket 3 is subject to used time of doing of high pressure water, can supports on the cell wall of first ring connected in star 121 and then expand, play seal action.
In such scheme, the end face of described first end 11 is provided with annular embedded groove 111, and the cross section of annular embedded groove 111 is substantially L-shaped.In described annular embedded groove 111, be provided with corresponding rubber seal 4.Described interface body 2 is provided with two relative " L " shape dog clutch 21 away from the end face of described the second end 12, the madial wall of described interface body 2 is provided with the draw-in groove 22 coordinating with described dog clutch 21, the corresponding dog clutch 21 of draw-in groove 22 is set to two, each draw-in groove 22 is one section of curve bath arranging along interface body 2 cell walls, curve bath is provided with two openings that stretch into for dog clutch 21, two curve baths are oppositely arranged, the setting of staggering of described dog clutch 21 and described draw-in groove 22.Like this, in the time need to increasing the length of water band, during by two water bands docking with fire hose coupling, two fire hose couplings are abutted together and are rotated a certain angle, on a fire hose coupling, dog clutch 21 snaps in the draw-in groove 22 of another fire hose coupling, and the rubber seal of two fire hose couplings is supported mutually together simultaneously.By cooperatively interacting of dog clutch 21 and draw-in groove 22, realize easy connection between water band, free rapidly.
The utility model also proposes the linkage structure of a kind of fire hose coupling and water band, for water band is more firmly fixed on packing holder 1, be provided with the second annular groove 122 at the outer tube wall of described the second end 121, described water band 5 is fixed in described the second annular groove 122 by the second fixed component, in an embodiment, described the second fixed component is three galvanized iron wires 7, by galvanized iron wire 7, water band 5 and packing holder 1 is tightly banded together, and places water band 5 and comes off.
Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable variation or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
