Abstract
The utility model relates to a hose industry field discloses a single wire screwed pipe. Including an electric wire and a steel wire, electric wire, steel wire and crust curl syntropy are coiled, the steel wire is copper facing or copperweld steel wire. This technical scheme has reduced the electric line number volume in the hose, and it is electrically conductive to utilize steel wire support piece to accomplish, when saving the electric wire cost, reduces the line body quantity of cladding in the screw hose for the single wire screwed pipe of the same length compares in prior art's scalable circular telegram hose extensible nature better, and the pliability when crooked is better, is difficult to to take place to roll over flat when curving, and manufacturing method is simple and convenient, easy to carry out.
Description
Technical field
This utility model is related to flexible pipe industrial circle, in particular to a kind of single conductor corrugated tubing.
Background technology
Existing scalable plastic flexible pipe, generally corrugated tubing, by being coated with the steel wire of plastics as skeleton, flexible plastic
Combine via winding process with inner wire and make scalable plastic flexible pipe as flexible pipe outer layer, and flexible pipe outer layer, generally only
With Telescopic.
The application for a patent for invention of applicant's Application No. 201310362456.8 discloses " a kind of Scalable electrifying flexible pipe ",
At least two wires are increased on the basis of existing scalable plastic flexible pipe, to reach the technology that Telescopic flexible pipe can be powered
Effect, but due to the Functional Requirement being powered, it is necessary at least two conducting wires are set in flexible pipe, must be set in flexible pipe in addition
In the support frame put, flexible pipe, the wire body of cladding is at least three, causes the collapsing length of scalable plastic flexible pipe to reduce, and bends
Property is also affected, and using effect is not good.
Utility model content
To solve above-mentioned technical problem, embodiment of the present utility model discloses a kind of single conductor corrugated tubing, further carries
High flexible pipe pliability and retractility.Concrete technical scheme is as follows：
A kind of single conductor corrugated tubing, including an electric wire and a steel wire, electric wire, steel wire and crust curl are same
To coiling；Steel wire is copper facing or copperweld steel wire.After steel wire copper-clad or copper facing, as can also play while bracing frame conduction
Effect, is coordinated with an electric wire, it is possible to realize the energization effect of screwed hose, reduces number of electrical lines, increases the soft of corrugated tubing
Toughness and ductility.
Further, crust is that the first outer layer and the second outer layer continuously overlap winding.Crust is rubber-plastics material extrusion molding
It is continuous band-shaped, wind curl, the latter circle in spiral is coated on the edge of previous circle when winding, overlap successively, from
And form continuous threaded tubular.For convenience of describing, two adjacent circles are referred to as into the first outer layer and the second outer layer.
Further, electric wire be wrapped in the first outer layer and the second outer layer it is overlapping between.Steel wire is arranged on single conductor spiral shell
The innermost layer of stricture of vagina pipe, the i.e. inside of the first outer layer and the second outer layer.Steel wire is supported on outside the first outer layer and second as bracing frame
The inside at the overlapping place of layer, so as to support the first outer layer and the second outer layer simultaneously.Wire intertwist at the outer rim of crust, and by under
One circle crust cladding, makes electric wire be always positioned between the first outer layer and the second outer layer, so that electric wire is subject to double shielding, it is ensured that
Be powered safety.
Further, clad is additionally provided with the outside of steel wire, clad is made up of insulant.Pacify to ensure that steel wire is powered
Entirely, the coated insulation layer on the outside of the steel wire.
Further, electric wire carries insulating barrier.
Compared with prior art, the beneficial effects of the utility model are as follows：
The technical program reduces the number of electrical lines in flexible pipe, completes conduction using wire supports, saves electric wire cost
While, reduction is coated on the wire body quantity in screwed hose so that the single conductor corrugated tubing of equal length is compared to existing skill
More preferably, pliability during bending more preferably, when curving is less likely to occur to roll over flat the Scalable electrifying flexible pipe ductility of art, and manufactures
Method is easy, it is easy to implement.

Specific embodiment
It is to make purpose, technical scheme and the advantage of this utility model embodiment clearer, new below in conjunction with this practicality
The accompanying drawing of type embodiment, is clearly and completely described to the technical scheme of this utility model embodiment.Obviously, it is described
Embodiment is a part of embodiment of the present utility model, rather than the embodiment of whole.Based on described of the present utility model
Embodiment, the every other embodiment obtained on the premise of without the need for creative work by those of ordinary skill in the art, all belongs to
In the scope of this utility model protection.
Embodiment of the present utility model one discloses a kind of single conductor corrugated tubing,
A kind of single conductor corrugated tubing, including 1, steel wire 4 of crust and an electric wire.Electric wire 1, steel wire 4 and crust
Curl is coiled in the same direction.Crust is continuous band-shaped for rubber-plastics material extrusion molding, winds curl, the latter circle in spiral
The edge of previous circle is coated on during winding, is overlapped successively, so as to form continuous threaded tubular.For convenience of describing, will be such as Fig. 2
Shown two adjacent circle crusts are referred to as the first outer layer 21 and the second outer layer 22.
Steel wire 4 is arranged on the innermost layer of single conductor corrugated tubing, the i.e. inside of the first outer layer 21 and the second outer layer 22.Steel wire 4
As bracing frame, the inside at 22 overlapping place of the first outer layer 21 and the second outer layer is supported on, so as to support the first outer layer 21 simultaneously
With the second outer layer 22.Steel wire 4 is copper facing or copperweld steel wire.To ensure that steel wire 4 is powered safety, insulation is provided with the outside of steel wire 4
Clad 3.After 4 copper-clad of steel wire or copper facing, as the effect that conduction can also be played while bracing frame, match somebody with somebody with an electric wire 1
Close, it is possible to realize the energization effect of screwed hose, reduce number of electrical lines, increase the pliability and ductility of corrugated tubing.
Electric wire 1 is wrapped at the outer rim of crust, and by next circle crust cladding, makes electric wire 1 be always positioned at the first outer layer 21
And second between outer layer 22；And electric wire 1 carries insulating barrier, so that electric wire is subject to the double shielding of crust and insulating barrier, it is ensured that
