Detailed description of the invention

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As Figure 1-3, be embodiment of the present utility model, it is the flexible duct 1 knitted by warp thread 3 and weft yarn 4 circle that a kind of circle knits pipe, the cross section of flexible duct 1 is rounded, and can random variation, its inside is also equipped with pull rope 2, is by chemical fibre or metal soft rope band.

During manufacture, the winding of fixed disk pressed on ring is put many warp thread 3 and is vertically arranged, the i.e. many circumferential uniform arrangements of warp thread 3, weft yarn 4 carries out justifying knitting with warp thread 3 by the shuttle of circular loom from bottom to top, and weft yarn 4 is same one thread (yarn of the yarn of multiply plying or multiply and sub-thread mixing) from the beginning to the end, weft yarn 4 one is on next (be namely one in one outer relative to the warp thread 3 of vertically arrangement) carries out justifying knitting through warp thread 3, and then tension is through weft yarn, flexible duct 1 can be obtained, the circle that the one-body molded independence of final formation is seamless knits pipe, without the need to sewing up, excess stock is not had to waste.

The girth in flexible duct 1 cross section is 56 ~ 188mm, and warp thread 3 density is for being 250 ~ 330/10cm, and weft yarn 4 density is 40 ~ 55/10cm, close-packed arrays between warp thread 3, is separated with the gap of 0.8-1.2mm between often enclosing between weft yarn 4.Warp thread 3 adopts terylene wire drawing, and weft yarn 4 adopts terylene precursor, or warp thread 3 and weft yarn 4 also can adopt polypropylene fibre or nylon respectively, and through flame treatment, anti-flammability is better.The end of pull rope 2 exceeds the port of flexible duct 1.Circle knits the built-in pull rope 2 of pipe, for drawing optical cable.

During use, one end of flexible duct 1, pull rope 2 can be connected with the old cable in passage, while the old cable of extraction, flexible duct 1 and pull rope 2 have all been routed in passage, the other end of pull rope 2 connects new cable, pull out pull rope 2 again, can new cable is routed in passage, complete the replacing of new and old cable.Because chemical fibre itself has certain slickness, more smooth through weft yarn institutional framework, weft yarn adopts multiply plying or the mixing of multiply and sub-thread, and therefore to knit the surfaces externally and internally of pipe all comparatively smooth for circle, and coefficient of friction is low, and convenient-laying is constructed.Circle knit pipe due to volume little, flexible strong, collapsible placement, storage space is little, convenient transportation, greatly reduces transport and the cost of storage, can avoid occurring reversing, beating the phenomenon such as ringlet, surge in optical cable laying process.Circle of the present utility model knits pipe can resist atrocious weather condition, particularly in sub-zero cold environment, because it has flexibility, even if therefore also can convenient-laying in the environment of cold, and pipe is higher in subzero fragility in common hard, be easy to fracture, inconvenience is laid.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
