Description

TECHNICAL FIELD

[0001] The utility model relates to a cable protection pipe, especially a cable protection pipe with inflatable sealing bag. BACKGROUND

[0002] There is a phenomenon that used pipe plugs are discarded everywhere in the power protection pipeline laying site, and it is difficult to find matching cable pipes for recycling, resulting in resource waste, in order to save resources and reuse, the utility model designs inflatable sealing bag, which is inflated, expanded and plugged when used, deflated and reduced to be taken out of the pipe opening when use is finished, and can be suitable for any kind of specification of cable protection pipe within the inflation range of the inflatable bag and is not limited in use times. SUMMARY

[0003] The utility model discloses a purpose to provide inflatable sealing bag, after entering the pipeline end, inflation, make sealing bag expand outwardly, until sealing bag and pipeline inner wall contact fully, thereby generating the friction between sealing bag and pipeline inner wall, prevent falling off, reach waterproof, dustproof effect.

[0004] The utility model discloses a technical scheme that solves its technical problems is: the cable protection pipe with inflatable sealing bag, including inflatable bag 1, the gas hole 2, the protection cover 3, the water -swelling sealing strip 4, the cable protection pipe 5;

[0005] Inflatable bag 1 is rectangular parallelepiped type when not inflation, and is cubic type after inflation, is rubber material, and includes four vertical surfaces 11 and two horizontal surfaces 12;

[0006] The gas hole 2 includes base 21, gas hole 22;

[0007] The water -swelling sealing strip 4 is long strip shape;

[0008] The gas hole 2 is located in the middle of the horizontal surface 12 of any one of the inflatable bag 1 and is perpendicular to the horizontal surface 12, the base 21 is embedded, exposes the gas hole 22, the protection cover 3 is connected with the gas hole 2 screw thread, the water -swelling sealing strip 4 is located on four vertical surfaces 11 and is in the middle of horizontal direction;

[0009] The inflatable bag 1 opens outward, and the water -swelling sealing strip 4 contacts with the inner wall of the cable protection pipe 5 in the inflation and expansion of the cable protection pipe 5 inside, and the water -swelling sealing strip 4 does not contact with the inner wall of the cable protection pipe 5 when the inflatable bag 1 shrinks.

[0010] The utility model discloses a cable protection pipe with inflatable sealing bag, including inflatable bag 1, inflation hole 2, protection cover 3, water -swelling sealing strip 4, cable protection pipe 5. BRIEF DESCRIPTION OF DRAWINGS

[0016] As Figure 5 Shown, with inflatable sealing bag's cable protection pipe, including inflatable bag 1, inflation hole 2, protection cover 3, water -swelling sealing strip 4, cable protection pipe 5.

[0017] As Figure 1 And Figure 2 Shown, the inflatable bag 1 is the cuboid type when not being inflated, is the square type after being inflated, is rubber material, including four vertical surfaces 11 and two horizontal surfaces 12.

[0018] As Figure 3 Shown, the inflation hole 2 includes base 21, inflation port 22.

[0019] As Figure 4 Shown, the inflation hole 2 is located the middle of the horizontal surface 12 of any one of the inflatable bag 1 and is perpendicular to the horizontal surface 12, the base 21 is embedded therein, exposes the inflation port 22, the protection cover 3 is threadedly connected with the inflation hole 2, the water -swelling sealing strip 4 is located the middle of four vertical surfaces 11 and is transversely.

[0020] As Figure 5 shown, the inflatable bag 1 opens outward, inflates and expands inside the cable protection tube 5, the water-swelling sealing strip 4 contacts the inner wall of the cable protection tube 5, increases the friction between the water-swelling sealing strip 4 and the cable protection tube 5, the inflatable bag 1 plays a role of plugging the cable protection tube port before the cable is put on, prevents water and dust, when the cable is put on, deflates, the inflatable bag 1 shrinks, is taken out from the cable protection tube 5, the inflatable bag 1 is made of rubber, can expand and shrink with the change of the inner diameter of the cable protection tube 5, is suitable for any kind of specification of the cable protection tube 5 within the expansion range of the inflatable bag 1.
