Description

Reinforcing structure of metal hose

Technical Field

The utility model relates to a hose construction.

Background

The periphery of the metal hose is provided with a braided structure which is generally single-layer braided or double-layer braided, the braided density is 60-100%, the structure is compact, the metal hose is not easy to loosen, the quality is good, the manufacturing process is simple, and the metal hose can be singly used for reinforcing the structure, but the metal hose has the defects that the stress concentration at the overlapping part of steel wires is easy to damage an inner pipe or generate broken wires, the pipe with larger specification is caused, the reinforcing effect is reduced in multiples, and the metal hose can only be applied to small-specification hoses; when being applied to the hose of big specification, then adopt and set up the winding layer at the inner tube skin, set up the weaving layer in the periphery on winding layer, can cover fine and close, the reinforcing is effectual, but, its structure is easy loose, in the quality, the preparation technology is complicated, produces the steel wire overlap easily, is in the steel wire on overlap department upper strata can impress the steel wire of lower floor in the inner tube when the pressurized to destroy the inner tube top layer, form the defect breach, lead to becoming invalid easily after tired.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a metal collapsible tube's reinforcing structure, the structure is inseparable, and the reinforcing is effectual, and preparation simple process adapts to and is used for all kinds of cast.

In order to achieve the above object, the utility model provides a metal collapsible tube's reinforcing structure, including the inner tube, the cover is equipped with the inner weaving layer in the periphery of inner tube, the periphery cover of inner weaving layer is equipped with the enhancement winding layer, the periphery cover of enhancement winding layer is equipped with the outer weaving layer.

Compared with the prior art, the beneficial effects of the utility model reside in that, establish earlier in the weaving layer cover in the inner tube periphery, can solve well and strengthen the direct winding of winding layer and appear sliding loose problem on the inner tube, simultaneously the inner weaving layer can evenly cover at the inner tube surface better, play good fixity, excessive extension or shortening when placing the inner tube pressurized, press from both sides tight enhancement winding layer through inside and outside weaving layer and can prevent the looseness of enhancement winding layer better, can also promote structural strength simultaneously, play the guard action to the inner tube better, the utility model discloses can be used for various types of metal collapsible tube.

As a further improvement, the interior winding layer of weaving layer periphery including the cover is established to the enhancement winding layer, the periphery cover on interior winding layer is equipped with outer winding layer, outer weaving layer cover is established in the periphery on outer winding layer, adopts double-deck winding can promote structural strength like this, can bear bigger pressure.

As the utility model discloses a further improvement, be provided with the compensation winding layer between outer winding layer and the interior winding layer, can make the fault-tolerant range of winding density obtain promoting like this, also can normal use when winding density grow or become, can use various types of winding equipment better, have higher adaptability.

As the utility model discloses a further improvement, winding opposite direction between interior winding layer, compensation winding layer and the outer winding layer is adjacent can not produce the overlap so can be so that the steel wire can share the ambient pressure who bears better during the winding.

As the utility model discloses a further improvement, the inner weaving layer is corrosion-resistant stainless steel wire, the outer weaving layer is spring stainless steel wire, can protect the inner tube effectively through the inner weaving layer like this, promotes the inner tube corrosion resisting property, can promote the compressive resistance performance through the outer weaving layer, conducts the external pressure of subducting better.

As a further improvement, the reinforced winding layer is a corrosion-resistant stainless steel wire, so that the corrosion resistance of the reinforced structure can be further improved, and the protection of the inner tube is improved.

Fig. 1 is a schematic structural diagram of the present invention.

Wherein, 1 inner tube, 2 interior weaving layers, 3 interior winding layers, 4 compensation winding layers, 5 outer winding layers, 6 outer weaving layers.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the reinforcing structure of a metal hose comprises an inner tube 1, wherein an inner braid 2 is sleeved on the outer periphery of the inner tube 1, a reinforcing winding layer is sleeved on the outer periphery of the inner braid 2, and an outer braid 6 is sleeved on the outer periphery of the reinforcing winding layer; the reinforced winding layer comprises an inner winding layer 3 sleeved on the periphery of the inner weaving layer 2, an outer winding layer 5 is sleeved on the periphery of the inner winding layer 3, and an outer weaving layer 6 is sleeved on the periphery of the outer winding layer 5; a compensation winding layer 4 is arranged between the outer winding layer 5 and the inner winding layer 3; the adjacent winding directions of the inner winding layer 3, the compensation winding layer 4 and the outer winding layer 5 are opposite; the inner braided layer 2 is a corrosion-resistant stainless steel wire, and the outer braided layer 6 is a spring stainless steel wire; the reinforced winding layer is made of corrosion-resistant stainless steel wires.

In the utility model, the inner weaving layer 2 made of the corrosion-resistant stainless steel wire can better shorten along with the extension of the inner tube 1, and has good close contact with the inner tube 1, good fixity and small stress of weaving cross points; the corrosion-resistant stainless steel wire is adopted for winding, the winding period is shortened, the close adhesion between the inner winding layer 3 and the inner weaving layer 2 is better, the strength after winding is effectively improved, and the better pressure resistance can be improved by the three winding layers; the outer braided layer 6 made of the spring stainless steel wire has better pressure resistance and fixity, and can better fix the inner winding layer 3, the compensation winding layer 4, the outer winding layer 5 and the inner braided layer 2, so that the inner winding layer 3, the compensation winding layer 4, the outer winding layer 5, the inner braided layer 2 and the outer braided layer 6 can form an integral structure, and the pressure resistance can be exerted more easily; and the inner weaving layer 2 can ensure that the protective performance of the steel wire is not influenced even if the problems of back strand winding, looseness and the like occur during winding.

The present invention is not limited to the above embodiments, and based on the technical solutions of the present disclosure, those skilled in the art can make some substitutions and transformations to some technical features without creative labor according to the disclosed technical contents, and these substitutions and transformations are all within the protection scope of the present invention.
