Abstract

The utility model discloses a multifunctional sleeve pipe. The multifunctional sleeve pipe comprises a twin-wire layer, a texture layer and a plastic layer, wherein the twin-wire layer comprises two metal wires with triangular and semi-round cross sections which are wound; the texture layer is a metal wire net wrapping the outer surface of the twin-wire layer; and the plastic layer is a plastic sleeve pipe wrapping the outer surface of the metal wire net. As the twin-wire structure is arranged in an inner layer of the multifunctional sleeve pipe, the spacing between the two broken openings of the sleeve pipe can keep constant through cooperation of the metal wires with the triangular and semi-round cross sections, the elongation rate can keep to be zero under a certain pulling force, and the compression ratio is zero. The multifunctional sleeve pipe has the characteristics of simple structure, convenience in use, easiness in processing and the like.

Description

A kind of Multifunctional casing

Technical field

The utility model relates to sleeve structure, is specifically related to a kind of Multifunctional casing.

Background technique

The structure of sleeve pipe is the mono-layer tube of only being made by a kind of material mostly in the prior art, even if flexible pipe the elongated pressurized of one side tension also can occur in bending and shorten.So both be not easy to the bending of sleeve pipe, and also can have changed simultaneously the distance between the two-port of pipe.This needs the demand of strict control drag-line extrusion will produce adverse influence for cable sleeve.Therefore be necessary the existing structure that escapes from is improved.

The model utility content

The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of in the situation that crooked arbitrarily, spacing between sleeve pipe two fractures can remain unchanged, and can keep specific elongation under certain pulling force is zero, and compression ratio is zero Multifunctional casing.

For achieving the above object, the technical solution of the utility model is a kind of Multifunctional casing of design, it is characterized in that, described sleeve pipe comprises mariages layer, plinthitic horizon and plastic layer, described mariages layer is that triangle and semicircle two kinds of wires are entwined by the cross section, described plinthitic horizon is the wire gaze that is wrapped in mariages layer outside, and described plastic layer is the plastic casing-pipe that is wrapped in the wire gaze outside.

Wherein preferred technological scheme is, described cross section is that triangle metal silk and cross section are that semicircle wire is arranged alternately, and described triangle is equilateral triangle, and the radius of described semicircle equates with leg-of-mutton height.

Further preferred technological scheme is that described cross section is that leg-of-mutton wire and cross section are to be close-packed arrays between the semicircular wire

Further preferred technological scheme also has, and is provided with pipe joint at the two ends of described sleeve pipe, is provided with thread section in inner face and/or the outside of described pipe joint.

Further preferred technological scheme also has, and described plinthitic horizon is the diagonal screen with wire or nylon establishment.

Advantage of the present utility model and beneficial effect are: owing to being provided with the mariages structure at the internal layer of this Multifunctional casing, cooperation by triangular-section silk and semi-circular cross-section silk, can realize that the spacing between sleeve pipe two fractures can remain unchanged, can keep specific elongation under certain pulling force is zero, and compression ratio is zero Multifunctional casing.This sleeve pipe has simple in structure, and is easy to use, is easy to the characteristics such as processing.

Description of drawings

Fig. 2 is the plan view of Fig. 1.

Among the figure: 1, mariages layer; 1-1, triangle; 1-2, semicircle; 2, plinthitic horizon; 3, plastic layer; 4, pipe joint; 5, thread section.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in Figure 1 and Figure 2, the utility model is a kind of Multifunctional casing, this sleeve pipe comprises mariages layer 1, plinthitic horizon 2 and plastic layer 3, mariages layer 1 is that triangle 1-1 and two kinds of wires of semicircle 1-2 are entwined by the cross section, plinthitic horizon 2 is the wire gazes that are wrapped in mariages layer 1 outside, and plastic layer 3 is the plastic casing-pipes that are wrapped in the wire gaze outside.

Preferred embodiment is in the utility model, and the cross section is that triangle 1-1 wire and cross section are that semicircle 1-2 wire is arranged alternately, and wherein triangle is equilateral triangle, and the radius of semicircle equates with leg-of-mutton height.

Further preferred embodiment is in the utility model, and the cross section is that leg-of-mutton wire and cross section are to be close-packed arrays between the semicircular wire

Further preferred embodiment also has in the utility model, is provided with pipe joint 4 at the two ends of sleeve pipe, is provided with thread section 5 in inner face and/or the outside of pipe joint 4.

Further preferred embodiment also has in the utility model, and described plinthitic horizon 2 is the diagonal screens with wire or nylon establishment.

The preparation process of the utility model Multifunctional casing is: first mariages is wrapped on the plug with Stetch Wrapping Machine, after the long length of setting that detours plug is extracted out, then wire gaze or nylon wire on the tube wall outer wrapping that is wound in by mariages, after load onto rubber plastic pipe at wire gaze or nylon wire overcoat again, and then pipe joint is loaded onto at the two ends of sleeve pipe.Wherein the internal diameter of mariages pipe is φ 8.5, and wire gaze or nylon wire overcoat external diameter are φ 10.3, and the external diameter of plastic pipe is φ 13.5, wire gaze or nylon wire, and rubber accounts for 30% in plastic pipe, and plastics account for 7 0%.

The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
