Description
Technical field
The utility model relates to a kind of connection set, belongs to fire-fighting truck telescopic jib technical field, especially a kind of water pipe connection set that stretches.
Background technique
Water pipe on the fire-fighting truck is laid on the work jib, and the work jib often adopts adjustable structure, and this just requires must installing can realize the connection set that both are flexible each other between water pipe and the water pipe.At present, the water pipe Telescopic mainly is employed in the mode of installing guide piston and guide sleeve between two water pipes and realizes that mainly there is following deficiency in this: the one, and, sealing effect is bad, is easy to take place percolating water phenomenon; The 2nd, complex structure, manufacture cost is high; The 3rd, between two water pipes, installing guide piston, require two water pipes of mutual socket to have big caliber poor, promptly inner tube diameter will be significantly less than the outer tube caliber, influence water mobile in pipe, particularly during multi-stage expansion, influences more obvious.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art; A kind of water pipe connection set that stretches is provided, and this device adopts inside and outside guide sleeve linkage structure, is provided with multiple-sealed and supporting ring; Socket is flexible each other to make connected two water pipes; And have excellent sealing ability, simple in structure, resistance to water-flow is little.
The utility model is realized through following technological scheme: a kind of water pipe connection set that stretches comprises connected tube, interior guide sleeve, outer guide sleeve, supporting ring and dust ring; It is characterized in that: outer guide sleeve is columnar structured; Inner axial hole comprises the hole of three sections different-diameters; Wherein one section left hole is an interior threaded hole; And on the hole wall in this hole, be processed with two radial screw bore, and on the bore area of other two sector hole, be processed with five road annular grooves, in groove, be equiped with O RunddichtringO, this special envelope I, supporting ring III, this special envelope II and dust ring respectively; Interior guide sleeve is columnar structured; Machined has axial hole, and the outside is the cylndrical surface of two sections different-diameters, on the right part cylndrical surface, is processed into the outside thread face; On the left part cylndrical surface, be processed with the bipassage ring connected in star, be equiped with supporting ring I and supporting ring II in the groove respectively; Be processed with two tapped blind holes vertically in the left part of interior guide sleeve.Connected tube comprises fixed tube and telescopic pipe, and the right-hand member outer surface of fixed tube is processed into outside thread, and matching with the left part interior threaded hole of outer guide sleeve is connected; The left end bore area of telescopic pipe is processed into internal thread, and matching with the right part outside thread of interior guide sleeve is connected.
The beneficial effect of the utility model is: owing to adopt inside and outside guide sleeve linkage structure, be provided with multiple-sealed and supporting ring, socket is flexible each other to make connected two water pipes; Has excellent sealing ability again; Flexible flexibility is good, simple in structure, and resistance to water-flow is little.
