Description
The utility model relates to a kind of joint of protecting the protection tube of cable and being used for above-mentioned protection tube of being used to.
At present, when carrying out the cable laying construction, for example lay cables underground or optical cable, often will provide a protection tube, make cable directly not be subjected to external force and the influence of poor environment on every side, and then increase the service life the cable of being laid.Traditional Cable protecting tube is when construction; the cable of being protected be pierced into protection tube, operation easier is big, particularly when the cable that needs protection is the multi beam cable; friction between the cable has more strengthened the difficulty of poling, workload and labour intensity when having increased construction.Traditional Cable protecting tube connects inconvenient, and has increased maintenance workload thus.And traditional protected mode is unfavorable for the connection of multi beam cable because the position of cable is fixing, because interweaving between the cable is unfavorable for the insulation between the cable.Simultaneously, traditional protection tube is generally single ply protective, and the protective capability that can provide is limited.
At above-mentioned prior art problems; the purpose of this utility model provides a kind of Cable protecting tube that can effectively protect the laying cable and the jointing of this protection tube; use this protection tube and jointing thereof to improve to lay the operating efficiency in the cable construction; reduce the workload in the construction, and help the maintenance in the cable use.
For achieving the above object; the technical solution adopted in the utility model is: a kind of Cable protecting tube; comprise outer tube and interior pipe; pipe is for a plurality of in described; described outer tube wall is provided with the location plush copper; pipe is connected and fixed by dowel between outer tube and the interior pipe in outer tube in described, also is connected and fixed by dowel between the interior pipe.
The shape of pipe can be square, circle or rhombus in above-mentioned.
The quantity of pipe can be 3,4,5 or a plurality of in above-mentioned a plurality of interior pipe was meant.
For above-mentioned protection tube is reliably connected; the utility model also provides a kind of jointing that is used for above-mentioned Cable protecting tube; this jointing comprises a connecting ring and the taper protuberance that joins with the connecting ring left-right symmetric; described taper protuberance comprises opening that adapts with dowel shape, quantity and the interior tube seat that adapts with interior tube shape, quantity, and with the location detent that adapts of plush copper.
Above-mentioned protection tube makes things convenient for the connection plush copper of attended operation in addition by the connection of jointing on the described connecting ring for convenience.
Above-mentioned protection tube is by the sealing of the junction of jointing for convenience, and the external diameter of described connecting ring and the external diameter of outer tube adapt.
By above-mentioned the technical solution adopted in the utility model as can be seen, the utility model reason and advantage that can achieve the goal fully is the following aspects:
1. because a plurality of interior pipes are arranged in the utility model outer tube, and be connected and fixed by dowel between the inner and outer pipe and between the interior pipe, make cable obtain the two-layer protection of outer tube and interior pipe, help prolonging the useful life of cable, and relatively-stationary inner and outer pipe, make that objectively the cable connection is more convenient, be difficult for makeing mistakes, and help the insulation between the cable, therefore use the utility model to lay cable, project quality further is protected; Simultaneously, because interior pipe in piercing into the process of cable, has played the effect of slideway, it is easier that cable is penetrated.
2. since the utility model outer tube in have a plurality of in the pipe, the number of interior pipe can be made as required, thus the utility model both be applicable to the protection single bunch cable, be suitable for again protecting the multi beam cable, convenient in the construction.
3. because the jointing of the connection protection tube that the utility model provides comprises the taper protuberance that joins with the connecting ring left-right symmetric; make attended operation easier; the external diameter of connecting ring and the external diameter of outer tube adapt; make the cable of junction be subjected to the sealing of more protecting and making things convenient for the protection tube junction; and the taper protuberance comprises and the dowel shape; the opening that quantity adapts and with interior tube shape; the interior tube seat that quantity adapts; and with the location detent that adapts of plush copper; make jointing and being connected of protection tube easier to be fixing; can not produce dislocation; therefore; adopt this jointing can make the connection of protection tube reliable, and can not cause damage cable.
4. owing to make things convenient for the connection plush copper of attended operation on the connecting ring of the jointing that the utility model provides in addition, make attended operation more convenient.
Below in conjunction with drawings and Examples the utility model is further elaborated.
