Abstract
The utility model discloses an optical cable channel inlet tube, including steel pipe, PVC coupling and plastic -aluminum pipe, the steel pipe be connected with the plastic -aluminum pipe through the PVC coupling, plastic -aluminum socle portion be circular arc angular form structure, at the steel pipe, the inside of PVC coupling and plastic -aluminum pipe have one can be through the cavity of optical cable. Plastic -aluminum pipe for L type structure. The steel bore of pipe the same with the internal diameter on PVC coupling upper portion. The internal diameter of PVC coupling lower part the same with the plastic -aluminum bore of pipe. The contact jaw of PVC coupling and steel pipe be the inverted circular truncated cone structure. The bending angle phase -match of bending angle and optical cable of plastic -aluminum pipe. The beneficial effects of the utility model are that: the lead -in cable channel uses the plastic -aluminum pipe, and because of the plastic -aluminum pipe can bend to different angles as required, the steel pipe can use the PVC coupling to fix with butt joint department of plastic -aluminum pipe, the materials used low price is purchase and is installed and use the comparison convenience.
Description
Technical field
The utility model relates to circuit safeguard device technical field, refers in particular to a kind of optical cable raceway groove inlet tube.
Background technology
In optical cable installation, when two ends lead-in cable raceway groove, we often can run into such problem, can be worn with steel pipe when shaft tower enters ground and tie up to protect optical cable not by outside destroy, but compare when turning, steel pipe lower end enters conduit line be difficult to process: if directly penetrate cable duct, optical cable easily hinder by hard object; If directly docked with steel pipe with pipe, cable bend angle too small (General Requirements cable bend angle is not less than 30 times of optic cable diameter), optical cable fibre core is easily impaired; If adopt between vertical tube and transverse tube and install PVC elbow additional, general angle of bend does not reach requirement, and not easily fixes; If directly made to certain angle is more difficult of tube bending, because steel pipe hardness is large, and easy modification time bending.
Utility model content
The purpose of this utility model is the shortcoming and defect overcoming prior art, provides a kind of cost-saving, optical cable raceway groove inlet tube easy to install.
The utility model is achieved through the following technical solutions:
A kind of optical cable raceway groove inlet tube, comprises steel pipe, pvc pipe joint and aluminium-plastic pipe, described steel pipe is connected with aluminium-plastic pipe by pvc pipe joint, be circular arc angular structure bottom described aluminium-plastic pipe, at steel pipe, the inside of pvc pipe joint and aluminium-plastic pipe have one can by the cavity of optical cable.
As preferably, described aluminium-plastic pipe is L-type structure.
As preferably, the internal diameter of described steel pipe is identical with the internal diameter on pvc pipe joint top.
As preferably, the internal diameter of described pvc pipe joint bottom is identical with the internal diameter of aluminium-plastic pipe.
As preferably, described pvc pipe joint and the contact jaw of steel pipe are reverse frustoconic structure.
As preferably, the angle of bend of described aluminium-plastic pipe and the angle of bend of optical cable match.
The utility model: vertical tube introduces ground under using steel pipe, and steel pipe and shaft tower use larynx hoop to be fixed; Lead-in cable raceway groove then uses aluminium-plastic pipe, and because aluminium-plastic pipe can bend to different angles as required, steel pipe and aluminium-plastic pipe joint can use pvc pipe joint to be fixed; Use material price is cheap, and purchase is installed and used more convenient.
Compared with prior art, the beneficial effects of the utility model are: lead-in cable raceway groove uses aluminium-plastic pipe, and because aluminium-plastic pipe can bend to different angles as required, steel pipe and aluminium-plastic pipe joint can use pvc pipe joint to be fixed; Use material price is cheap, and purchase is installed and used more convenient.
Accompanying drawing explanation
Below by embodiment, by reference to the accompanying drawings the utility model is further described.
Fig. 1 is structural representation of the present utility model;
1 is steel pipe, and 2 is pvc pipe joint, and 3 is aluminium-plastic pipe, and 4 is cavity, and 5 is optical cable.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail:
As shown in Figure 1, a kind of optical cable raceway groove inlet tube, comprise steel pipe 1, pvc pipe joint 2 and aluminium-plastic pipe 3, described steel pipe 1 is connected with aluminium-plastic pipe 3 by pvc pipe joint 2, be circular arc angular structure bottom described aluminium-plastic pipe 3, at steel pipe 1, the inside of pvc pipe joint 2 and aluminium-plastic pipe 3 have one can by the cavity 4 of optical cable 5.Described aluminium-plastic pipe 3 is L-type structure.The internal diameter of described steel pipe 1 is identical with the internal diameter on pvc pipe joint 2 top.The internal diameter of described pvc pipe joint 2 bottom is identical with the internal diameter of aluminium-plastic pipe 3.Described pvc pipe joint 2 is reverse frustoconic structure with the contact jaw of steel pipe 1.The angle of bend of described aluminium-plastic pipe 3 and the angle of bend of optical cable 5 match.
The above is only preferred embodiment of the present utility model; not technical scope of the present utility model is imposed any restrictions; therefore every above embodiment is done according to technical spirit of the present utility model some improvement, distortion and modification, all still belong to the protection domain of technical solutions of the utility model.
Claims (6)
