PURPOSE: A protection device of an underground distribution line is provided to buffer vertical pressure and impact by arranging a cable protection tube between an upper body and a lower cover. CONSTITUTION: An upper body(10) is combined in a lower cover(20). A plurality of connectors(23) are formed on the upper side of the lower cover with a constant interval. A bridge(25) is formed in the lower side of the lower cover. A damper(26) is formed in the lower part of the bridge. A support leg(30) includes a guide part and an axial part. The guide part is symmetrically formed in both sides of the outer surface of the lower cover. The upper side of the axial part moves along the guide part. The lower part of the axial unit is fixed in the surface. A display band(24) is detachably connected between the protrusion ends of the connection unit. |
