Abstract
The utility model discloses a bury ground wire and cable carbon element screwed pipe for sheath, including inlayer body and outer screwed pipe, its characterized in that: outer screwed pipe is the heliciform and sets up outside the inlayer body, be equipped with bending end in the body, bending end forms whole staircase structure with the body outer wall, bending end and body outer wall fixed connection, the bending end outside is equipped with fine screw thread, the body includes front end and rear end, front end and rear end all are equipped with the rotatory screw thread that is used for the erection joint, on the terminal surface of front end and rear end, still be equipped with soft cross -section.
Description
Technical field
This utility model relates to tubing field, is specifically related to a kind of buried wire cable cover(ing) carbon element corrugated tubing.
Background technology
Carbon element corrugated tubing also known as " carbon element recoil inserts pipe ", is called for short carbon element pipe, be main material production molding with high density polyethylene (HDPE) and modifying carbon cable sheath tube, use extrusion molding and unique rotational molding technology technology.Its outward appearance is black single wall helical form, so be otherwise known as " single wall carbon element pipe ".Carbon element corrugated tubing is a kind of Novel sheath tube material that cable, optical cable laying engineering are commonly used, is to substitute pvc pipe, pipe of cement, cast iron pipe, the ideal product of steel pipe.The connected mode of steel band reinforced winding pipe mainly has: hot-melt extruded welding, Electric thermal smelting belt welding and heat-shrinkable tube (carrying) connect.It is with its distinctive screw-like thing moulding, carbon element corrugated tube has high intensity, high tenacity corrosion resistant, high temperature resistant, insulation resistance is high, good flame resistance, light weight, life-span length, the multiple advantage such as is unlikely to deform, this carbon element corrugated tube is widely used to city street lamp circuit ground covering project, electric railway electric power, communication cable lay ground covering project, highway electric power, the project for construction and upgrading of communications facility, the underground cable engineering of construction of residential quarters engineering and park and large-scale public place of entertainment, is optimal underground cable sheath tubing.
But camber that existing carbon element corrugated tubing exists is inadequate, when needs are turned, overall corrugated tubing is difficult to the defect bent, and it is the simplest that this is accomplished by one structure, it is easier to the equipment of bending solves problem.
Utility model content
This utility model is for existing buried wire cable cover(ing) carbon element corrugated tubing, the structural instability existed, and body does not allows flexible defect, it is provided that a kind of buried wire cable cover(ing) carbon element corrugated tubing solves the problems referred to above.
Of the present utility model it is achieved in that a kind of buried wire cable cover(ing) carbon element corrugated tubing, including internal layer body and outer layer corrugated tubing, it is external that described outer layer corrugated tubing is arranged at inner tube in the shape of a spiral, described body is provided with curved end, described curved end and tube wall form overall staircase structure, curved end is fixing with tube wall to be connected, and is provided with fine thread outside described curved end；Described body includes that front-end and back-end, described front-end and back-end are equipped with the rotation screw thread for erection joint, on the end face of described front-end and back-end, is additionally provided with soft cross section.
Theory in this utility model is: by arranging a curved end, thus in the case of the softness not reducing overall body, so that corrugated tubing preferably bends.And by before and after tank body end arrange soft cross section make people dock body when avoid injury, and two joints pick up after the compactest.
In this utility model, as further scheme, the fine thread spacing of described curved end is 0.3-0.5cm.The effect of fine thread is, strengthens the intensity at the interface of curved end.
In this utility model, as further scheme, described body and curved end junction are provided with the system point of projection.
In this utility model, as further scheme, described body and curved end junction are provided with sealing gasket.
The effect of above-mentioned two scheme is the intensity strengthening body with curved end junction, and increases sealing.
In this utility model, as further scheme, described front-end and back-end are double-decker, and it is enhancement Layer at the middle and upper levels.
In this utility model, as further scheme, the thickness of described body is 0.6-1.8cm.
In this utility model, as further scheme, the lateral length of described curved end is 5-8cm.
The beneficial effects of the utility model are:
1. the carbon element corrugated tubing of this utility model design, can effectively strengthen the intensity of body, and effectively realizes the docking of body, while the hardness of whole body is strengthened, by arranging curved end, body can be bent.
2. this utility model passes through strengthening process, effectively raises the life-span of tubing, and makes tubing can quickly bury electric wire.
3, this utility model is safe and reliable, and cost of manufacture is reasonable, it is simple to use of the same trade.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model；
Parts title and sequence number in figure:
Body 1, corrugated tubing 2, curved end 3, fine thread 4, system point 5, front end 6, rear end 7.
Detailed description of the invention
Describing this utility model below in conjunction with drawings and Examples, following example explain with utility model optimal effectiveness.
Embodiment 1:
Such as Fig. 1, a kind of buried wire cable cover(ing) carbon element corrugated tubing, including internal layer body 1 and outer layer corrugated tubing 2, outer layer corrugated tubing 2 is arranged at outside internal layer body 1 in the shape of a spiral, body 1 is provided with curved end 3, curved end 3 and body 1 stair outer wall form overall staircase structure, curved end 3 is fixing with body 1 outer wall to be connected, curved end 3 is outside is provided with fine thread 4, the system point 5 of projection it is provided with in body and curved end 3 junction, and body 1 and curved end 3 junction are provided with sealing gasket (being not drawn in figure), thus prevent pad from leaking；Body includes that front end 6 and rear end 7, front end 6 and rear end 7 are equipped with the rotation screw thread for erection joint, and on the end face of front end 6 and rear end 7, is additionally provided with soft cross section.And front end 6 and rear end 7 are double-decker, it is enhancement Layer (being not drawn in figure) at the middle and upper levels, and its enhancement Layer uses rigid plastics material.The thickness of the present embodiment middle tube body 1 is 0.6cm, and the lateral length of curved end is 5cm.The when of installation, by connector, front end 6 and the rear end 7 of 2 pipes are coupled together, and make the body 1 can be with the bending of wide-angle by curved end 3.
Embodiment 2:
Difference from Example 1 is, the fine thread spacing marking described curved end is 0.5cm, and the thickness of described body is 1.8cm.
Last it is noted that obviously, above-described embodiment is only used to this utility model example is clearly described, and not to the restriction implemented.For the those of ordinary skill in described field, can also make other changes in different forms on the basis of the above description.Here without also cannot be to all of embodiment party's formula with exhaustive.And the obvious change thus amplified out or variation still in protection domain of the present utility model among.
