Abstract

The utility model relates to a long-life wearproof silicon core pipe comprising an HDPE high density polyethylene base tube. The inner side of the HDPE high density polyethylene base tube is provided with a silicon core layer which is composed of solid lubricant silicon colloid. A plurality of noctilucence indication color bands are coated on the outermost side of the HDPE high density polyethylene base tube along the central axis of the HDPE high density polyethylene base tube. The outer side of the silicon core layer is provided with protrusion blocks which are in thread rotation distribution. The protrusion blocks on the silicon core layer are embedded in the inner side of the HDPE high density polyethylene base tube so as to enable the silicon core layer and the HDPE high density polyethylene base tube to be connected into one piece. The long-life wearproof silicon core pipe is simple in structure and reasonable in design; conventional silicon core pipes are improved slightly, so that the silicon core pipes can be suitable for installation requirements of optical cables in the photo-communication field better; the HDPE high density polyethylene base tube and the silicon core layer are combined more tightly and reliably; the service life of the silicon core pipe can be improved; and wear-resistant performance of the silicon core pipe is improved.

Description

High life wear-resisting type silicon core pipe

Technical field

The utility model relates to the technical field of silicon core pipe, especially a kind of high life wear-resisting type silicon core pipe.

Background technology

In known technical field, in optical communication industry optical cable transmission field, except the insulating coating of optical cable itself need to have stronger insulativity, sealing and water proofing property, the pipeline of installing for the traction of optical cable also will have stronger insulativity, sealing and water proofing property.Although the optical cable of using under in prior art can possess above-mentioned characteristic with pipeline, but it is inner not through special processing, the insulating coating of itself and optical cable is got and can produce very large friction when dilatory inserting, to pipeline and optical cable, it is all a very large loss, also increased to insert and got and the power of described needs when dilatory, to the user of service, brought very big fiber crops.

Silicon core pipe is the NEW TYPE OF COMPOSITE pipeline of a kind of inwall with silica gel matter kollag, good seal performance, and resistance to chemical attack, construction costs is low, is widely used in highway, the optical cable communications network system of railway etc.HDPE silicon core pipe is the NEW TYPE OF COMPOSITE pipeline of a kind of inwall with silica gel matter kollag, is called for short silicone tube.By three synchronous extrusion claddings of plastic extruder, main raw material(s) is high density polyethylene, and sandwich layer is the kollag silica gel matter that friction factor is minimum.How better designing the structure of silicon core pipe, to adapt to the installation needs of optical communication industry optical cable, is very necessary.

The utility model content

The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of high life wear-resisting type silicon core pipe is provided.

The utility model solves the technical scheme that its technical matters adopts: a kind of high life wear-resisting type silicon core pipe, comprise HDPE high density polyethylene parent tube, be provided with the silicon core layer formed by kollag silica gel matter in the inboard of described HDPE high density polyethylene parent tube, central axis along HDPE high density polyethylene parent tube is coated with some luminous marks colour bands in the outermost of described HDPE high density polyethylene parent tube, be provided with in the outside of described silicon core layer and be the protruding block that the screw thread rotation shape distributes, and the protruding block on described silicon core layer all is embedded in the inboard of HDPE high density polyethylene parent tube and makes the setting that is connected as a single entity of silicon core layer and HDPE high density polyethylene parent tube.

Further, as a kind of concrete embodiment, the wall thickness of the high density polyethylene of HDPE described in the utility model parent tube is 3mm.

Further, as a kind of concrete embodiment, the wall thickness of silicon core layer described in the utility model is 2.5mm.

Further, as a kind of concrete embodiment, the quantity of the colour band of luminous marks described in the utility model is 2.

Further, as a kind of concrete embodiment, the quantity of the colour band of luminous marks described in the utility model is 3.

The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, existing silicon core pipe is carried out to little improvement, more to adapt to the installation needs of optical communication industry optical cable, the combination of its HDPE high density polyethylene parent tube and silicon core layer is more closely reliable, can improve its serviceable life, increase its anti-wear performance.
