Abstract
The utility model relates to a plastic pipe with changeable flexibility. The flexible plastic pipe comprises a plurality of metal pipe buckles whose longitudinal section is S-shaped. The plurality of metal pipe buckles are buckled together to form a metal pipe body. The flexible plastic pipe further comprises a hot melt adhesive, a first polytetrafluoroethylene layer tightly attached to the inwall of the metal pipe body, and a second olytetrafluoroethylene layer covering the outer part of the metal pipe body. Filling gaps are disposed between the metal pipe body and the first polytetrafluoroethylene layer and between the metal pipe body and the second polytetrafluoroethylene layer, and filled with the hot melt adhesive. The flexible plastic pipe is advantaged by being novel in structure, convenient in bending and molding, good in molding effects, and good in stability. The flexible plastic pipe can be repeatedly bent and molded without the shape changed.
Description
Technical field
The utility model relates to a kind of metal hose.
Background technology
Existing metal tubulation has most as the protection tube of protection cable; general metal tube is all integrated hard tube; although there is certain flexible ability and bending resistance; but its flexible ability; rigidity bending resistance is also not too beneficial to the cabling of cable and holding wire, if customization arc pipe, not only cost is high; and measurement calculating is loaded down with trivial details, use very inconvenience.There are on the market now a lot of metal hoses,
These metal hoses are to consist of the mutual snapping of a plurality of metal pipe threads; the Chinese utility model patent that is CN201663395 as notification number discloses the metal hose of a kind of inside shoe PVC; although it has flexible ability easily by bending; easily there is cracking mouthful in the metal tube buckle of bending state; if establish protective layer in not having; inner cable cannot waterproof, anticorrosion and oxidized; even if inside establish PVC protective layer; also easily because bending is pullled or is isolated; therefore; need to a kind ofly there is elasticity anti-bending strength, and possess the metal hose of certain flexible ability.
Summary of the invention
Goal of the invention of the present utility model is for a kind of novel structure is provided, and has the metal hose of good flexing resistance and pull resistance, and this metal hose also has the performance of resistance to burning and armoured magnetic field, is beneficial to as holding wire protection tube.
In order to realize foregoing invention object, the utility model has adopted following technical scheme:
A metal hose, is formed and metal tube, the silica gel muscle of annular that can bending and the protective layer that is close to metal tube inwall form by the S-shaped metal pipe thread snapping in a plurality of vertical sections; Between the metal pipe thread of described adjacent mutual snapping, leave relatively-movable snapping gap, silica gel muscle elasticity is filled in snapping gap.
Described metal pipe thread consists of the first arc shaped hook ring portion, the first cylindrical portion, bending ring portion, the second cylindrical portion and the second arc shaped hook ring portion inwardly outwardly; The second cylindrical portion internal diameter is greater than the external diameter of the first cylindrical portion; First cylindrical portion one end is connected with the first arc shaped hook ring portion root, and the other end is connected with bending ring portion; Second cylindrical portion one end is connected with bending ring portion, and the other end is connected with the second arc shaped hook ring portion root; The external diameter of described the first arc shaped hook ring portion is less than the second cylindrical portion internal diameter; Described the second arc shaped hook ring portion internal diameter is greater than the first cylindrical portion external diameter; The upper and lower two ends of described silica gel muscle elasticity is pressed between the second arc shaped hook ring portion on the first arc shaped hook ring portion and adjacent metal pipe thread; The upper and lower inside and outside both sides of described silica gel muscle are pressed on respectively between the second cylindrical portion on described the first cylindrical portion and adjacent metal pipe thread.
As preferably, described protective layer is polytetrafluoroethylene floor.
Adopted the metal hose of technique scheme; the skin of this metal hose consists of the metal pipe thread snapping of adjacent mutual snapping; internal layer is established protective layer, leaves relatively-movable snapping gap between the metal pipe thread of adjacent mutual snapping, and silica gel muscle elasticity is filled in snapping gap.Once such metal hose by bending after; extruding silica gel muscle; under the effect that need to recover in the elastic deformation of silica gel muscle; can there is certain elastic reactance bending effect; compare with existing metal hard tube; not only be beneficial to cable routing, also there is the good protective effect of metal hard tube, prevent that cable and cable from being damaged by excessive bending simultaneously.In addition, be equally under the effect of silica gel muscle, this metal hose also has certain elasticity tensile property, prevents from being broken easily in use, makes this metal hose self very durable.
In a word; the advantage of this metal hose is: novel structure; there is elastic reactance bending and tensile property; not only stable shaped; and applicability is good, overcome the limited applicability of rigid metal hard tube, be difficult for being stretched by random bending simultaneously; cable is had to good protective effect, and self durability is very good.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment:
A kind of metal hose as depicted in figs. 1 and 2, is formed and metal tube 2, the silica gel muscle 3 of annular that can bending and the protective layer that is close to metal tube 2 inwalls form by S-shaped metal pipe thread 21 snappings in a plurality of vertical sections.Between the metal pipe thread 21 of above-mentioned adjacent mutual snapping, leave relatively-movable snapping gap 20, silica gel muscle 3 elasticity are filled in snapping gap 20.Above-mentioned protective layer 1 is polytetrafluoroethylene floor, and the fusing point of polytetrafluoroethylene is 327 ℃ of left and right, waterproof not only, and there is good insulation, resistance to burning, decay resistance, protection cable is not damaged slowly.
Above-mentioned metal pipe thread 21 consists of the first arc shaped hook ring portion 210, the first cylindrical portion 211, bending ring portion 212, the second cylindrical portion 213 and the second arc shaped hook ring portion 214 inwardly outwardly.The second cylindrical portion 213 internal diameters are greater than the external diameter of the first cylindrical portion 211.First cylindrical portion 211 one end are connected with the first arc shaped hook ring portion 210 roots, and the other end is connected with bending ring portion 212.Second cylindrical portion 213 one end are connected with bending ring portion 212, and the other end is connected with the second arc shaped hook ring portion 214 roots.For snapping better and make the metal tube 2 that snapping forms can bending, dimensionally, the external diameter of the first arc shaped hook ring portion 210 be less than the second cylindrical portion 213 internal diameters, and the second arc shaped hook ring portion 214 internal diameters are greater than the first cylindrical portion 211 external diameters.Silica gel muscle Shang Xia 3 two ends elasticity be pressed between the second arc shaped hook ring portion 214 on the first arc shaped hook ring portion 210 and adjacent metal pipe thread 21.Silica gel muscle is pressed on respectively between the second cylindrical portion 213 on described the first cylindrical portion 211 and adjacent metal pipe thread 21 inside and outside both sides Shang Xia 3.
When metal tube 2 is during by bending, the silica gel muscle 3 of bending part inner side, by the first upper and lower arc shaped hook ring portion 210 and the second arc shaped hook ring portion 214 extruding, has good elastic recovery properties after 3 elastic deformations of silica gel muscle, thereby forms good elastic reactance bending effect.Similarly, also because silica gel muscle 3 is formed good elasticity tension effect by the first upper and lower arc shaped hook ring portion 210 and the opposing movement of the second arc shaped hook ring portion 214 extruding.Therefore, it is especially suitable for use in the protection of distant signal line cabling.
