Abstract
The utility model is a kind of threading steel pipe, and particularly a kind of ectonexine is all covered with the threading steel pipe of epoxy resin protective layer.Comprise threading steel pipe; the outer wall of described threading steel pipe is provided with zinc coat; the inwall of described threading steel pipe is provided with interior epoxy resin protective layer, and the surface of described zinc coat is provided with outer epoxy resin protective layer, and the inwall of described interior epoxy resin protective layer is provided with equally distributed abrasionproof raised line.Ectonexine is all covered with a threading steel pipe for epoxy resin protective layer, improves electric wire useful life, improves fail safe.
Description
Technical field
The utility model is a kind of threading steel pipe, and particularly a kind of ectonexine is all covered with the threading steel pipe of epoxy resin protective layer.
Background technology
Threading steel pipe of the prior art, traditional protective layer is outside zinc-plated, easily scratches, wet is easily corroded, and because be all metal material, cannot insulate, if inner electric wire cortex is because external force is impaired, easily accidents caused.
Summary of the invention
Utility model is mainly to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and effectively protects electric wire, and a kind of ectonexine increasing the service life is all covered with the threading steel pipe of epoxy resin protective layer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of ectonexine is all covered with the threading steel pipe of epoxy resin protective layer; comprise threading steel pipe; the outer wall of described threading steel pipe is provided with zinc coat; the inwall of described threading steel pipe is provided with interior epoxy resin protective layer; the surface of described zinc coat is provided with outer epoxy resin protective layer, and the inwall of described interior epoxy resin protective layer is provided with equally distributed abrasionproof raised line.
As preferably, described interior epoxy resin protective layer and the thickness of outer epoxy resin protective layer are respectively 3-10mm.
Interior epoxy resin protective layer and outer epoxy resin protective layer have effectively protected threading steel pipe not to be damaged.Abrasionproof raised line interval contacting of electric wire and interior epoxy resin protective layer, protection electric wire is not damaged.
Therefore, a kind of ectonexine that the utility model provides is all covered with the threading steel pipe of epoxy resin protective layer, improves electric wire useful life, improves fail safe.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
