The groove is arranged between the first optical cable hole and the inner wall of the upper cover, and the groove is matched and embedded with the protrusion.
The first cable hole and the second cable hole are the same in size, and the central lines of the first cable hole and the second cable hole are on the same horizontal line.
And a rubber sealing ring is arranged at the joint of the lower cover and the steel pipe.
The upper cover, the lower cover, the bulges and the connecting rings are all made of soft silica gel materials.
The utility model discloses an actively beneficial effect is:
1. the utility model provides a shutoff stopper adopts software silica gel, and silica gel has insulating nature, waterproof, high temperature resistant, cold-resistant etc. nature, has solved the shutoff not tight, has paintd uneven, the desiccation splits, easily drops tenesmus scheduling problem, and simultaneously, the inside optical cable parcel of steel pipe is gone into to the shutoff stopper, avoids the optical cable that causes because of pnematic friction to be cut apart the problem.
2. The utility model adopts the upper and lower layers of structural design, the upper cover adopts the conical design, which is beneficial to draining water and is not easy to accumulate water and snow, and one end away from the conical tip is provided with a groove, which is convenient to be embedded, combined and fixed with the bulge on the lower cover; the upper part of the lower cover is provided with a bulge which can prevent water from entering the side surface, and the bottom connecting ring adopts a threaded design and is attached to the inside of the steel pipe in a multilayer water-blocking mode.
3. The utility model discloses lower cover and steel pipe laminating department are provided with rubber seal, and when the steel pipe caused the damage to plugging material because of time or environment, at first destroy rubber seal, when changing, only need to change the rubber circle and just can recycle, practiced thrift the material, reduced the input, had fine economic benefits.
