At least one sidewall of described conduit body is provided with by the ribs that is bent to form.

The bottom in the U-shaped cross section of described conduit body is along on the conduit direction, and equidistantly symmetric arrangement has the L-shaped hook of outside bending.

The bottom in the U-shaped cross section of described conduit body is along on the conduit direction, and equidistantly symmetric arrangement has the hook of outside bending, and one of them hook is L-shaped; Place, the bottom Plane intersects in the U-shaped cross section of another hook plane, place and conduit body, its outer end is offered porose.

The one side of described spring nut be provided with can with the tooth road of rack rails engagement, the spacing in tooth road is consistent with the spacing of rack rails; The another side of spring nut is provided with spring.

The width of described hook is consistent with the spacing of rack rails.

Two sidewalls of described conduit body are respectively through repeatedly bending formation twice ribs.

The utility model adopts said structure, and the rack rails on the conduit body total length can effectively increase the permanent position of ancillary facility, has increased the choice of permanent position; Sliding stop can be effectively prevented in the mechanical snap of conduit body and spring nut or engagement, and has improved the ability of opposing shock and vibration loads, strengthens the ancillary item reliability of fixation; The U-shaped cross-section of conduit body and the ribs of two side thereof can effectively improve its supporting capacity and strengthen conduit body and concrete bond stress, make its pre-buried structure more effective, and be more difficult loosening; The hook of bending can effectively hook is hung object, be convenient to pre-buried fixing, and the perforation on one of them hook can be used for auxiliary its to hook by the extension object, strengthens validity, avoids pre-buried inefficacy.

As seen, adopt the utility model of said structure, compared with prior art, can by pre-buried conduit body in concrete, realize dustless installation, and the setting by said structure, can improve its pre-buried validity, stability and reliability, be more conducive to the installation, fixing of ancillary item.

The specific embodiment

Below in conjunction with specific embodiments and the drawings the utility model is further described.

Embodiment 1:

As Fig. 1, Fig. 3, shown in Figure 4, the omnipotent conduit of dustless installation comprises conduit body 1, spring nut 6 and bolt 9.

As shown in Figure 1, the cross section of conduit body 1 is a U-shaped, turn of bilge 10 in the inside bending of the dual-side of the open end of its U-shaped is stretched out and constituted, and turn of bilge 10 constitutes symmetrical J respectively with the dual-side of U-shaped in this, and the flange of interior turn of bilge 10 is provided with rack rails 3.

The two side of conduit body 1 constitutes twice ribs 4 up and down through four bendings respectively.The U-shaped cross-section of conduit body 1 and the ribs of two side 4 thereof can effectively improve its supporting capacity and strengthen conduit body and concrete bond stress, make its pre-buried structure more effective, and be more difficult loosening.

The bottom of the U-shaped cross-section of conduit body 1 is along on the conduit direction, and equidistantly symmetric arrangement has the L-shaped hook of outside bending 2, and the hook 2 of bending can effectively hook is hung object, is convenient to pre-buried fixing.
