Description
Technical field
The utility model is related to cable protection technical field, and in particular to a kind of New cable protecting pipe.
Background technology
Power cable is typically laid on underground, in order to improve the life-span of cable, slows down the aging of insulation sheath, often needs pair
Cable is obstructed with external environment condition, and cable is sealed using protection pipe, prevents infringement of the external environment condition to cable.It is single
Power cable protecting pipe is difficult long, needs to expend larger tractive force when laying cable wherein if long, and protect
The cost of transportation of pillar will be improved, and be spliced so power cable protecting pipe typically is set into segmentation structure.But one
As connecting method be bolted, easily cause loosening, meanwhile, protection pipe is colded and heat succeed each other by external environment condition
When influence, the expansion and contraction distortion of its own can produce influence to junction.
The content of the invention
For problems of the prior art, the utility model is by using corrugated stainless steel tubing and located at stainless steel wave
PE bellowss inside line pipe as adjacent cable protection pipe connector so that realize and be flexible coupling between cable protection pipe, subtract
Protection pipe connection loosens after few vibrations etc. are used for a long time, and causes water inlet etc. in pipe, being capable of effective connection cable so as to provide one kind
Protection pipe, extends protection pipe service life, improves New cable protecting pipe of the cable using safety.
To achieve the above object, the technical solution adopted in the utility model is：A kind of New cable protecting pipe, its feature exists
Include in, the protection pipe some by the end to end main body tube of connector, the two ends of main body tube are respectively equipped with the first method
Orchid, connector includes corrugated stainless steel tubing and PE bellowss, and the two ends of corrugated stainless steel tubing have been respectively fixedly connected with the second method
Orchid, PE bellowss are located inside corrugated stainless steel tubing, and the two ends of PE bellowss are respectively and fixedly installed in second flange, the second method
It is blue to be connected with first flange.
The internal diameter of PE bellowss is equal with main body bore.
Sealing gasket is provided between second flange and first flange.
It is connected by screw between corrugated stainless steel tubing and second flange, screw is located inside corrugated stainless steel tubing.
Operation principle of the present utility model is：Adjacent two main body tubes are joined end to end by connector, on connector not
Rust corrugated steel pipe and PE bellowss to realize connection living between main body tube, corrugated stainless steel tubing have certain compression strength and
Resist bending ability, PE bellowss have flame retardant effect, insulating capacity and resist bending ability.
The beneficial effects of the utility model are：It is cold that New cable protecting pipe of the present utility model can reduce vibrations, heat expansion
The influence to protection pipe junction such as contracting, places the service life of Elongated cable wire and protection pipe, with easy for installation, uses the longevity
The advantage that life is long, protecting effect is good.
Brief description of the drawings
Fig. 1 is profile of the present utility model.
Embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, a kind of New cable protecting pipe, the protection pipe includes some end to end by connector
Main body tube 1, the two ends of main body tube 1 are respectively equipped with first flange 2, and connector includes corrugated stainless steel tubing 3 and PE bellowss 4,
The two ends of corrugated stainless steel tubing 3 have been respectively fixedly connected with second flange 5, and PE bellowss 4 are located inside corrugated stainless steel tubing 3, PE
The two ends of bellows 4 are respectively and fixedly installed in the two ends of the corrugated stainless steel tubing 4 connected second flange 5 of outside, second flange 5 with
First flange 2 is in mating connection.
The internal diameter of PE bellowss 4 is equal with the internal diameter of main body tube 1 so that the inside of PE bellowss 4 is internally formed one with main body tube 1
The individual passage for smoothly placing cable, facilitates the traction of cable.
Waterproof sealing gasket 6 is provided between second flange 5 and first flange 2, is bolted to connection, prevents water from entering pipe
It is interior.
It is connected by screw between corrugated stainless steel tubing 3 and second flange 5, screw is located inside corrugated stainless steel tubing 3.Spiral shell
Nail is arranged on inside corrugated stainless steel tubing 3, it is to avoid directly contacted with the external world, it is to avoid screw is by corrosion, PE bellowss and the second method
It is connected by screw between orchid 5.
Adjacent two main bodys 1 are managed to be joined end to end by connector, corrugated stainless steel tubing 3 and PE bellowss 4 on connector
It is flexible coupling so that being realized between main body tube 1, corrugated stainless steel tubing 3 has certain compression strength and resist bending ability, PE ripples
Pipe 4 has flame retardant effect, insulating capacity and resist bending ability, so as to protect cable.
Preferred embodiment of the present utility model described in detail above, it will be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations without creative work according to design of the present utility model, therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
