Detailed Description
As shown in fig. 1, bury formula composite cable locally, including an outer protective layer 1, an interior installation cavity 12 has in the outer protective layer 1, interior installation cavity 12 bottom surface is formed with supporting part 9, supporting part 9 extends towards 1 length direction of outer protective layer, supporting part 9 is inside to be formed with multichannel hollow out construction, fixed embedding sets up one and supports box 6 on the horizontal plane of supporting part 9 upper end, the both sides of supporting box 6 are bent and are set up an extension 5, extension 5 tiling is on supporting part 9 upper end horizontal plane, extension 5 and the top tiling of supporting box 6 set up a heart yearn structure, department sets up a median septum 3 perpendicularly in the middle of the heart yearn structure upper end, median septum 3 lays along 1 length direction of outer protective layer, the bottom part of median septum 3 inserts in the heart yearn structure.
In this embodiment, the heart yearn structure includes heart yearn outer protective layer 11, the department forms a solid connecting portion 7 in the middle of the heart yearn outer protective layer 11, 3 bottoms of median septum insert and are fixed in connecting portion 7, a hollow heart yearn installation cavity has in the heart yearn outer protective layer 11, more than one cable core 4 tiling is laid in the heart yearn installation cavity, the bottom surface of the heart yearn outer protective layer 11 in the heart yearn structure is fixed with the up end of extension 5 and is beaten the glue water-stop seal, extension 5 and the contact of supporting part 9 up.
In this embodiment, the extending portion 5 and the supporting box 6 are of an integral structure, the supporting box 6 is internally provided with a yielding cavity 8 with an opening at the upper end surface, when the middle partition plate 3 is pressed down, two sides of the core wire structure are bent and tilt to approach towards the middle partition plate 3, as shown in fig. 2, once a downward pressure is applied, the middle partition plate 3 can be used for supporting, the middle partition plate 3 is pressed down to bend the connecting portion 7, the core wire structure tilts upwards, the tilted core wire structure drives the extending portion 5 to tilt upwards, at this time, the middle partition plate 3, the extending portion 5 and the core wire outer protection layer 11 are finally in a state perpendicular to the horizontal plane, the vertical force is used for resisting shearing, the elastic extending portion is used for realizing downward pressure buffering, after the pressure of the middle partition plate is relieved, the extending portion can recover to deform under the elastic acting force thereof to resist the next pressure, and the extending portion and the core wire outer protection layer are finally in a perpendicular state, the combined structure in a vertical state is utilized to resist shearing and pressing down, so that the safety is greatly improved.
In this embodiment, the top of the middle partition board 3 is buckled into the outer protection layer 1, a thickened portion 2 is formed at the top of the outer protection layer 1, the thickened portion 2 is a horizontal plane relative to one side of the middle partition board, a positioning buckle groove for buckling the middle partition board 3 is formed at the bottom of the horizontal plane, and the thickened portion 2 increases the top pressure resistance of the cable and increases the strength.
