Abstract
The invention relates to a flexible energizing hose, and belongs to the technical field of hoses. The flexible energizing hose comprises a supporting piece, wrapping pieces and at least two guide lines. The supporting piece is formed by coiling rib strips in a spiral mode in the length direction of the hose. The wrapping pieces are formed by coiling sheet-shaped soft plastic strips in the same direction with the supporting piece as a framework. The middle of the section of each sheet-shaped soft plastic strip is provided with a containing cavity which contains the at least two guide lines, the two sides of the section of each sheet-shaped soft plastic strip extend to form a left wing and a right wing respectively, and the edges of the adjacent left wing and the right wing are sealed and combined after each wrapping piece is coiled. When the hose is in a shrinkage state, the adjacent left wing and the right wing are mutually folded, and an inner spiral folded wall inside the supporting framework is formed. Not only does the flexible energizing hose keep the function that an existing flexible hose can be flexible easily, but also due to the fact that the wrapping pieces are evenly placed in the spiral supporting framework and are folded in the supporting framework, the flexible energizing hose has the advantages of being not prone to being abraded, easy to clean and the like, the effective double-layer protection is obtained, and the energization is safer and more reliable.
Description
Technical field
The present invention relates to a kind of bellows, especially a kind of Scalable electrifying flexible pipe, belong to technical field of hoses.
Background technology
Existing scalable plastic flexible pipe, as skeleton, flexible plastic is made via the winding process combination as the flexible pipe skin, usually only has Telescopic by the line muscle of the steel wire that is coated with plastics.
Retrieval is found, the patent No. is that the United States Patent (USP) of US7735523 discloses a kind of Scalable electrifying flexible pipe, this flexible pipe comprises strutting piece, coating member, one group of wire, strutting piece has space disc around forming by strip material along long axis direction, coating member covers interval by thermoplastic and the part strutting piece forms, and folding outwardly at interval region, wire is between layer of thermoplastic material.Its advantage is under the prerequisite that does not affect the original pliable and tough telescopicing performance of flexible pipe, has properly settled the powerup issue of flexible pipe one end to the other end, thereby can meet by the user demand of flexible pipe to the products such as dust catcher of power source power supply.
Yet all there is obvious shortcoming in above-mentioned prior art: the one, coating member is folding outwardly at interval region, easily is worn in therefore using; The 2nd, burst is sheltered evil people and countenance evil practices, and is difficult to cleaning; The 3rd, the outer field cladding of multi-thread conductor, wall thickness is limited by Telescopic, has short-circuit risks.In addition, the structure of prior art only has lower powered powering-on function, such as strutting piece by two coppered steel wires as electrical conductor etc., when for relatively high power, switching on, can't meet the requirement of safety standard.
Application number is that 200920045797.1 Chinese utility model patent discloses a kind of Scalable electrifying flexible pipe, this flexible pipe comprises hose body, the tube wall of described hose body forms the spiral groove caved inward, and in the tube wall between described adjacent trenches, is mounted with spiral helicine wire.This utility model, having properly settled in hose end consuming device powerup issue, has kept the original scalability of flexible pipe, and the characteristic such as pliable and tough, crooked.Yet this flexible pipe adopts the strutting piece of copper covered steel, can only signal low tension, still be difficult to meet the demand of actual power.
Summary of the invention
The object of the invention is to: propose a kind of capable of expansion and contraction and coating member is not easy to wear, the Scalable electrifying flexible pipe of easy cleaning.
In order to reach above purpose, the bellows of switching on of the present invention comprises strutting piece, coating member and at least two wires, described strutting piece consists of (being generally copperweld steel wire or the steel wire) rib along described hose length direction coiled coil, described coating member forms as the sheet flexible plastics bar that skeleton coils in the same way by take strutting piece, in the middle part of the cross section of described sheet flexible plastics bar, have at least two wires are enclosed in to inclusion cavity wherein, and left wing and right flank are extended respectively in the both sides, cross section, adjacent left wing and the combination of right flank edge seal after the coating member coiling; When described flexible pipe was in contraction state, described adjacent left wing and right flank were mutually folding, form the inside spin folded wall that is positioned at described support frame.
Compared with prior art, the present invention has not only kept existing bellows light flexible function freely, and because coating member evenly is placed between the spirality support frame and is folded in support frame, therefore has the remarkable advantages such as not easy to wear, easy cleaning.In addition; the present invention can be overmolding to the support frame for supporting and switching on by the electric wire more than two or three or plating (bag) copper steel silk; and former, have outside the wire protective layer coating thermoplastic material again, thereby obtained effective double shielding, make to switch on safer reliable.
Further, described inclusion cavity is between adjacent two ribs of coiled coil.
Further, described inclusion cavity all is enclosed in two wires and rib wherein.
Further, described two wires lay respectively at the rib both sides as strutting piece and holding wire.
Further, described inclusion cavity is enclosed in one of two wires and adjacent two ribs wherein.
Further, described rib consists of the metal inside protective layer outer with being coated on inner core, described wire outer wrapping insulating barrier.
The accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.

Embodiment
Embodiment mono-
The Scalable electrifying flexible pipe of the present embodiment as shown in Figure 1, 2, comprises strutting piece 1, coating member 2 and two wires 3, and strutting piece 1 consists of the copperweld steel wire rib along hose length direction coiled coil.Coating member 2 forms as the sheet flexible plastics bar that skeleton coils in the same way by take strutting piece 1, in the middle part of the cross section of this sheet flexible plastics bar, have two wires 3 are enclosed in to inclusion cavity 2-3 wherein, inclusion cavity 2-3 is between adjacent two ribs of coiled coil, and left wing 2-1 and right flank 2-2 are extended respectively in its both sides, cross section.Wire 3 is enclosed with insulating barrier 3-1.The adjacent 2-1 of left wing and right flank 2-2 edge seal combinations after coating member 2 coilings.When flexible pipe was in contraction state, adjacent left wing 2-1 and right flank 2-2 were mutually folding, form the inside spin folded wall that is positioned at support frame.The strutting piece 1 that the copperweld steel wire rib forms can be simultaneously as holding wire.Rib consists of the metal inside protective layer 1-1 outer with being coated on inner core, like this, helps metal inside anticorrosion, and can be by the metal inside transmission of electric signals.
Embodiment bis-
