Description
Technical field
This utility model is related to fire fighting device field, specifically a kind of telescopic fire main.
Background technology
In prior art, such as Authorization Notice No., disclosed in the utility model patent of CN 203868541U, " high abrasion is high-elastic
Power is stretched water pipe " including body and the influent side coupling assembly and water outlet side coupling assembly that are separately mounted to body two ends；Body
Including water flowing inner core and the overcoat being set in outside water flowing inner core, light wall pipe group of the water flowing inner core by two-layer above high abrasion high-tension
Into, overcoat be high density, it is wear-resistant and it is seamless can fold cloth set.But, there is complex structure, use not aspect, hydraulic pressure too high in which
When the defect such as easily slip.
Utility model content
The purpose of this utility model is to provide a kind of telescopic fire main, fundamentally solves the problems referred to above, its
With simple and compact for structure, convenient to use, maintenance cost is low, long service life, the low advantage of fault rate.
For achieving the above object, this utility model provides following technical scheme：The telescopic fire main includes water
Pipe and the shell component being arranged on outside water pipe, shell element end are provided with discharge opening, and shell component front end is provided with engagement ring,
It is characterized in that：The shell component includes some end to end shell units incremented by successively by discharge opening external diameter, each to manage
Shell unit is provided with shell lockhole, is mutually linked by inserting the shell lock pin of shell lockhole between shell unit；Discharge opening and water pipe
Water side is engaged, and water pipe end is provided with latch components, and latch components include spacing lead sheath in water pipe, are arranged in lead sheath
Spring, the pipe lock pin being symmetricly set in lead sheath, the pipe joint that water pipe end is assemblied in by pipe pipe lock pin and spring.
Described shell unit one end is provided with inwall and is provided with female thread structure, and shell unit outer wall is provided with axle sleeve, outside axle sleeve
Wall is provided with externally threaded flange, and the shell unit of front end is screwed on the shell unit of rear end by axle sleeve.
The water pipe includes outer tube and the corrugated tube being arranged in outer tube.
The beneficial effects of the utility model：The shell unit composition that shell component is connected by lock pin using some head and the tail,
When not in use, shell cell size is retractable into, so as to save space.During use, can as needed, by detent configuration
The length of the sluicing section that fire extinguisher canvas hose is made up of some shell units is adjusted freely.Pipe joint is fixed by spring, detent configuration
On water pipe, slippage is effectively prevent, while convenient dismantle.
