Abstract
An inner conduit comprises an inner pipe, a metal layer and an outer layer. The interior of the inner pipe is hollow to form a hole; the metal layer is wrapped on the external surface of the inner pipe; and the outer layer is wrapped on the external surface of the metal layer. The metal layer wrapped out of the inner pipe is additionally provided, the metal layer is protected from gnawing by mice and other damage, and thereby, the optical cable or cable in the hole is protected.
Description
Technical field
The utility model relates to the equipment for communication pipe, relates in particular to be used to the inner catheter of wearing optical cable or cable.
Background technology
At present, the inner catheter that uses in the communication pipe is plastic tube, and this plastic tube is arranged in the pipeline and with the inspection shaft of these pipeline both sides and communicates.Optical cable or cable are arranged in this plastic tube, and such inner catheter environment of living in is abominable, such as, in the place that mouse is arranged, in actual use, mouse often occurs sting bad inner catheter, and then, damage optical cable or cable and affect communication.In addition, in communication pipe, communication pipe in the past comprises inspection shaft and is communicated with the concrete duct of inspection shaft, present communication pipe comprises inspection shaft and is communicated with the plastic tube of inspection shaft, no matter be pipe of cement or plastic tube, all be in concrete duct or plastic tube, to wear first described inner catheter, then in inner catheter, wear optical cable or cable, for concrete duct, the rough inner surface of concrete duct is so that wear the inner catheter difficulty, for inner catheter, when wearing optical cable and cable, since the surface of optical cable or cable and inner catheter the inner surface friction so that wear optical cable or cable is difficult.
The utility model content
The problem that the utility model solves is that existing inner catheter can cause optical cable or cable to be bitten by animal and the problem damaged.
For addressing the above problem, the utility model provides a kind of inner catheter to comprise inner tube, metal level and skin, wherein, and the inner hollow of described inner tube and consist of hole; Described metal level is wrapped in the outer surface of inner tube; Described skin is wrapped in the outer surface of metal level.
As a kind of improvement project, described inner tube is plastic tube, and described skin is plastic layer.
As a kind of improvement project, the thickness of the tube wall of described inner tube is 1 millimeter: described outer field thickness is 1 millimeter:
As a kind of improvement project, described metal level is netted steel wire floor.
As a kind of improvement project, the thickness of described metal level is 2 millimeters or 1 millimeter.
As a kind of improvement project, the inner surface of described inner tube and outer field outer surface are coated with respectively lubricating oil.
As a kind of improvement project, the diameter of described hole is 28mm.
Compared with prior art, the utlity model has following advantage:
1. owing to being provided with metal level and metal level wraps up described inner tube, like this, mouse etc. can't sting bad metal level, thereby protection is positioned at optical cable or the cable of hole.
2. because inner surface and the outer field outer surface of described inner tube are coated with respectively lubricating oil, like this, be arranged in the process of concrete duct or plastic conduit in inner tube, the effect of lubricating oil can be easily so that inner catheter passes concrete duct or plastic tube; Optical cable or cable are being located in the process of inner catheter, the lubricating oil on the inner surface of this inner tube so that optical cable or cable easily pass, so, wear optical cable or cable is easy.
Description of drawings
Fig. 1 is the sectional view of the utility model inner catheter.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, below in conjunction with embodiment and cooperate accompanying drawing to be described in detail.
See also Fig. 1, the utility model inner catheter comprises inner tube 1, metal level 2 and outer 3.Described inner tube 1 inner hollow and consist of hole 11, like this, optical cable or cable can pass this hole 11, and the diameter of this hole 11 is 28mm, and in the present embodiment, described inner tube 1 is plastic tube, and the thickness of tube wall is 1 millimeter.Described metal level 2 is wrapped in the outer surface of inner tube 1, netted steel wire floor in the time of in the present embodiment, and thickness is 2 millimeters or 1 millimeter.Described outer 3 are wrapped in the outer surface of metal level 2, describe take inner tube 1 as reference, and metal level 2 comprises inner surface and outer surface, and the inner surface of metal level 2 contacts with the outer surface of inner tube 1, and the outer surface of metal level 2 contacts with outer 3.
Because be provided with metal level 2 and the described inner tube 1 of metal level 2 parcels, like this, mouse etc. can't sting the bad metal level 2 that has, thereby protection is positioned at optical cable or the cable of hole 11.
Please continue to consult Fig. 1, as a kind of improvement project, the inner surface of described inner tube 1 and outer field outer surface are coated with respectively lubricating oil, like this, be arranged in the process of concrete duct or plastic conduit in inner tube 1, the effect of lubricating oil can be easily so that inner catheter passes concrete duct or plastic tube; Optical cable or cable are being located in the process of inner catheter, the lubricating oil on the inner surface of this inner tube 1 so that optical cable or cable easily pass, so, wear optical cable or cable is easy.
Claims (7)
1. inner catheter is characterized in that: comprise inner tube, metal level and skin, wherein, the inner hollow of described inner tube and consist of hole; Described metal level is wrapped in the outer surface of inner tube; Described skin is wrapped in the outer surface of metal level.
