Abstract

The utility model discloses a reinforced plastic hose provided with a corrugated hose body. Compared with the prior art, the utility model is characterized in that metal conducting wires are inlaid in the wall of a hose body; the metal conducting wires are composed of steel wires or the combination of steel wires, copper wires and aluminum wires, or adopt double-strand or multi-strand metal core plastic compound wires. The utility model has the advantages of beautiful appearance, high durability, abrasion resistance and external force resistance, and can be also used as conducting cables which are convenient for the use of electric apparatus such as dust collectors, etc.

Description

Reinforced plastic hose

The utility model relates to the pipe in engineering element or the parts, it is a kind of flexible pipe, being a kind of the have rubber of the reinforced layer in the embedding tube wall or flexible pipe that soft plastic is made furtherly, specifically, is a kind of plastic flexible pipe bellows wall, that the reinforcer that embeds tube wall is arranged that has.

The purposes of plastic film capicitor is very extensive, in a large number as ventilation, waste pipes such as vacuum cleaner, family expenses cooker hood, washing machines, and on other home appliances and the industrial products.But traditional plastic film capicitor only is made of separately plastics, and intensity and antifriction performance are all limited, and externally produces gross distortion and break under the weight.

The purpose of this utility model provides the enhanced plastic flexible pipe of a kind of intensity height, durable, applied range.

Technical solution of the present utility model is: a kind of enhanced plastic flexible pipe, have the corrugated body, and the difference of itself and prior art is: be embedded with plain conductor at tube body wall.

Plain conductor in the utility model is mixed with copper, aluminum steel by one or two, three steel or steel and constitutes.Certainly, also can adopt other suitable metal wire rod or mixed forms.

Plain conductor of the present utility model adopts bifilar metal-cored plastics recombination line, or three strands, the metal-cored plastics recombination line of multiply.Certainly, also can adopt one, the metal-cored plastic cord of the sub-thread more than two or three or three, or adopt other suitable construction forms.

Metal-cored employing steel wire in the utility model, or steel and copper, aluminum steel is compound.Certainly, also can adopt other suitable metal core wire structures.

Body in the utility model is formed by the coiling of PVC plastic pellicle.Certainly, also can or adopt other suitable structural type by other suitable plastic film coilings.

Plain conductor in the utility model is embedded on the inboard wall of tube body.Certainly, also can be embedded in other proper site.

The utility model has the advantages that: simple in structure, beautiful shape, degree of finish is good, wear-resisting, durable, the intensity height, the external force resistance ability is strong, externally indeformable under the weight, do not break, pressurized 80KG is indeformable after tested, vibratory test surpasses 10,000 subsurface no wrinkles, do not come unstuck, especially can utilize the interior wire of tube wall as electric lead, as utilize metal core wire in the tube wall on the vacuum cleaner operating handle by dress switch (the lead pressure test: 3KV does not puncture), not only be user-friendly to but also using electricity wisely, and made things convenient for maintenance etc., can be widely used as the sweep-up pipe on the vacuum cleaner, smoke-ejecting pipe on the cooker hood, waste pipe on the washing machine etc., and many family expenses and industrial occasion, alternative traditional plastic flexible pipe.Produce easily, invest little, instant effect, cost is low, extensive market has good economic benefit prospect.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a kind of enhanced plastic hose construction schematic representation of the present utility model.

Fig. 2 is the thin bilge construction schematic representation of a kind of tube wall of enhanced plastic flexible pipe of the present utility model.

Fig. 1 has described an embodiment of the present utility model.In soft plastic bellows body 1(polythene or PVC or other suitable plastic) tube wall be embedded with metal core wire 3, metal core wire 3 outer one deck plastic bushing or the plastic sheaths 2 of also having wrapped up, certainly, also can be without plastic sheath 2 under suitable situation, but metal core wire directly is embedded in the tube wall.

Fig. 2 has described a kind of structural pipe wall of the present utility model.It is made after twining outside a bifilar wire-core plastics recombination line and having covered PVC plastic film layers 1, bifilar wire-core plastics recombination line is made of plastic protecting casing 2 and wire cored wire 3, certainly, wire cored wire 3 also can adopt steel wire or steel wire and mixing of copper wire, aluminium wire to form structure.

The utility model can adopt following method manufacturing: with the bifilar wire-core plastics recombination line of customization or by two copper cash and the three core plastics recombination lines that steel wire is formed, by torsion machine coiled wire spring, bourdon tube is finalized the design by required size by driving nut again by the uniform pitch fiber tube, be positioned on the steel pipe, then to coiling PVC plastic pellicle on the film machine, flexible pipe after intact drops into baking oven its temperature with 120 ℃～140 ℃ is smoked, dry by the fire afterwards the mouth of pipe in addition suitably processing just become manufactured good.Certainly, also can make of other appropriate method.
