The utility model discloses frictional force in the time of can further reducing the threading, the optical cable that shuttles back and forth is easier, improves threading efficiency, the cable length of the disposable threading of extension reduces the optical cable fusion number to the loss of reducible light wave reduces the probability that the optical cable damaged simultaneously when the threading, protect the optical cable better, improves the threading quality, equipment energy consumption when reducing the threading.
Description
Technical field
The utility model relates to a kind of communication tube, and more particularly, it relates to a kind of profile of tooth silicone pipes.
Background technology
Communication tube is the parts for the protection of ground buried fiber optic cable, and silicone pipes is common a kind of communication tube.The interior pipe of existing silicone pipes is all smooth circular structure, although circular configuration has the advantage that structure is simply beneficial to production, but have the following disadvantages: when wearing optical cable, optical cable can abut against on inner tubal wall, form larger friction force, cause threading difficulty, need to use high-power threader, very easily cause optical cable to damage.Publication number is that the utility model of CN204068165U discloses a kind of communication silicone pipes on Dec 31st, 2014, comprise skin that high density polyethylene makes and the silicon core layer that uniform application is made up of silica gel matter kollag on described outer inwall, described skin and described silicon core layer axile displacement are arranged, described silicone pipes one end is provided with the hollow exposing to silicone pipes end between described skin and silicon core layer, the joint of truncated cone, the described silicone pipes other end to be provided with and to extend to silicone pipes inside between described skin and silicon core layer, the interface coordinated with described joint.The communication silicone pipes of this utility model is by arranging the plug and interface that mutually coincide at two ends, make two silicone pipes when splicing, only need the plug of a wherein silicone pipes be inserted in the interface of another root silicone pipes, O-ring seal is superscribed in the contact position of plug and interface, simply, easy to operate, the sealing simultaneously between two silicone pipes is better.But the kollag that this utility model mainly relies on silicon core layer to provide reduces friction when wearing optical cable, and lubricant effect is limited, if optical cable is more or comparatively slightly, resistance during threading still can be larger.
Utility model content
Existing silicone pipes lubricant effect is limited; very easily threading difficulty is caused because friction is too large when wearing optical cable; for overcoming this defect; the utility model provides one can reduce energy consumption; improve optical cable threading efficiency, improve optical cable underpass length once, thus reduce the loss of light wave; reduce the probability that optical cable damages when threading, protect the profile of tooth silicone pipes of optical cable better.
The technical solution of the utility model is: a kind of profile of tooth silicone pipes, comprises inner and outer tubes, and interior pipe is positioned at the passage of outer tube, and the inwall of interior pipe is provided with protruding interior pipe tooth.Outer tube of the present utility model is for the protection of optical cable; bear external pressure; interior pipe is used for optical cable threading; protection optical cable; the inwall of profile of tooth can make the air-flow of threading air pump by the gap of tooth, optical cable be held up; do not touch tube wall when optical cable is shuttled back and forth in pipeline or seldom contact, such optical cable is easy to shuttle back and forth in pipe.
As preferably, outer tube is closely coated on outside interior pipe.Outer tube and interior pipe fuse together by extrusion molding mode, and such job operation can realize the nested of outer tube and interior pipe easily, and can make not produce relative displacement between inner and outer pipes, make outer tube play the effect of pipe and optical cable in protection.
As preferably, interior tube thickness is less than outer tube thickness.Strengthen outer tube thickness when silicone pipes internal diameter is certain and can improve silicone pipes integral rigidity, there is when construction is imbedded better bending strength.
As preferably, the profile of tooth of interior pipe tooth is triangle.The inwall of profile of tooth decreases and optical cable contact area, thus makes optical cable easier to be movable in pipe, is easy to air-flow is passed through.Air-flow holds up optical cable by backlash, reduces optical cable activity friction force, and the optical cable that shuttles back and forth is easier, can lengthen cable length and reduce optical cable welding number of times, reduce light wave loss.
As an alternative, the profile of tooth of interior pipe tooth is trapezoidal.Stepped tooth is relatively blunt, more not fragile optical cable during threading.
The beneficial effects of the utility model are:
Improve optical cable threading efficiency.The utility model can reduce friction force during threading further, and the optical cable that shuttles back and forth is easier.
Improve threading quality.Owing to using the utility model threading can reduce friction, therefore can lengthen the cable length of disposable threading, reduce optical cable welding number of times, thus the loss of light wave can be reduced, reduce the probability that optical cable damages when threading simultaneously, protect optical cable better.
Reduce energy consumption.Owing to using the utility model threading can reduce friction, plant capacity consumption can be reduced with during threader threading.

Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation after the utility model threading;
Fig. 3 is a kind of using state schematic diagram of the present utility model.
In figure, 1-outer tube, pipe in 2-, pipe tooth in 3-, 4-sandstone, 5-optical cable.
Embodiment
Below in conjunction with accompanying drawing specific embodiment, the utility model is described in further detail.
Embodiment 1:
As shown in Figures 1 to 4, a kind of profile of tooth silicone pipes, comprise interior pipe 2 and outer tube 1, interior pipe 2 is positioned at the passage of outer tube 1, and the inwall of interior pipe 2 is provided with protruding interior pipe tooth 3, and the profile of tooth of interior pipe tooth 3 is triangle.Outer tube 1 is closely coated on outside interior pipe 2, and outer tube 1 is different with interior pipe 2 material, and outer tube 1 is PE extruded material, and interior pipe 2 is silica gel extruded material, and outer tube 1 and interior pipe 2 are fused together by extrusion process, the center line of interior pipe 2 and the centerline parallel of outer tube 1 and overlap.
When optical cable 5 penetrates profile of tooth silicone pipes, near pipe tooth 3 in interior pipe, friction can be produced between the two when wearing and sending optical cable 5, so the fewer friction of both contacts is fewer under gravity.When many optical cables 5 penetrate simultaneously, optical cable 5 becomes greatly with the extruding force of the interior pipe tooth 3 of interior pipe 2, now be pressed into from interior pipe tooth 3 with forced airflow, optical cable 5 can be pushed to centre, and makes it unsettled or half unsettled, the remarkable minimizing of such friction force meeting.During construction, silicone pipes is embedded in sandstone 4, may produce flexural deformation, adds optical cable 5 and walk difficulty in pipeline, and the application of this case can walk difficulty by reduction optical cable 5 greatly.
