Abstract
The utility model relates to an extension-type electrified flexible pipe and belongs to the flexible pipe technology field. The flexible pipe comprises a supporting component, a cladding component and at least two leads. The supporting component is formed by a rib which is spirally coiled along a length direction of the flexible pipe. The cladding component is formed by a sheet-shape soft plastic strip which is coiled along a same direction and takes the supporting component as a skeleton. A central section of a cross section of the sheet-shape soft plastic strip possesses a containing chamber which surrounds the at least two leads and two sides of the cross section are extended out of a left wing and a right wing respectively. After the cladding component is coiled, adjacent edges of the left wing and the right wing are sealed and combined. When the flexible pipe is in a contraction state, the adjacent left wing and the right wing are mutually folded so as to form an inner spiral folding wall located in a support skeleton. The extension-type electrified flexible pipe of the utility model maintains a freely and easily telescopic function of the current telescopic flexible pipe. Because the cladding component is uniformly placed among spiral support skeletons and is folded in the support skeletons, the flexible pipe possesses advantages that the flexible pipe is not easy to wear; cleaning is easy to perform and so on. Effective double layer protection is obtained so that energization is safe and reliable.
Description
Technical field

Background technology
Existing scalable plastic flexible pipe, by the line muscle of steel wire that is coated with plastics, as skeleton, flexible plastic is made via winding process combination as flexible pipe skin, conventionally only has Telescopic.
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 part strutting piece forms, and folding outwardly at interval region, wire is between layer of thermoplastic material.Its advantage is not affect under the prerequisite of 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 the user demand to the products such as dust catcher of power source power supply by flexible pipe.
Yet all there is obvious shortcoming in above-mentioned prior art: the one, coating member is folding outwardly at interval region, in therefore using, is easily worn; 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 switching on for relatively high power, cannot 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 caving inward, and is mounted with spiral helicine wire in the tube wall between described adjacent trenches.The 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, be still difficult to meet the demand of actual power.
Utility model content
The purpose of this utility model is: 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 object, Scalable electrifying flexible pipe of the present utility model 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 both sides, cross section, adjacent left wing and the combination of right flank edge seal after coating member coiling; When described flexible pipe is during in contraction state, described adjacent left wing and right flank are mutually folding, form the inside spin folded wall that is positioned at support frame.
Compared with prior art, the utility model has not only kept existing bellows light flexible function freely, therefore and because coating member is evenly placed between spirality support frame and is folded in support frame, there is the remarkable advantages such as not easy to wear, easy cleaning.In addition; the utility model can be overmolding to the support frame for supporting and switching on by more than two or three electric wire or plating (bag) copper steel silks; and former, there is wire protective layer coating thermoplastic material again outward, 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 is all 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 metal inside and the protective layer being coated on outside inner core, described wire outer wrapping insulating barrier.
