For solving the problems of the technologies described above, the utility model provides technical scheme as follows:
A kind of wire-threading device bump joint, comprise the flange seat that middle part has the first manhole, the below of described flange seat is provided with the first straight steel pipe for connecting roof, and the top of described flange seat is provided with the flange of screw bolt and nut connection;
The periphery of described flange is provided with at least two bolt perforation, the middle part of described flange has second manhole corresponding with described first manhole, described second manhole is connected with the second straight steel pipe, and the end of described second straight steel pipe is connected with downward opening curve bend;
Be provided with set bolt ring-type inverted T shape groove in described flange seat, the below of described ring-type inverted T shape groove is provided with opening, and the upper surface of described flange seat is provided with o-ring groove, is provided with O RunddichtringO in described o-ring groove.
Further, described bolt is T-shaped bolt, and the head of described bolt is positioned at described ring-type inverted T shape groove, and described nut is positioned at the top of described flange.
Further, described flange seat and the first straight steel pipe, described flange and the second straight steel pipe, described second straight steel pipe and curve bend are and are welded to connect.
Further, plain washer is provided with between described nut and flange.
Further, described nut is hex nut.
The utility model has following beneficial effect:
Wire-threading device bump joint of the present utility model, by after the first manhole and the second manhole correspondence before using, by the cooperation of screw bolt and nut, flange is fixed in flange seat, the utility model is fixed on roof, wire-threading device is arranged on curve bend, when needs adjustment wire-threading device, unclamp nut, rotary flange, flange can drive bolt to move along the T-shaped groove of the ring-type in flange seat when rotated, after determining the position of wire-threading device, flange is fixed by fastening nut; Opening below ring-type inverted T shape groove both can facilitate construction bolt by water vent, and downward opening curve bend serves the effect of waterproof, and o-ring groove and the O RunddichtringO of flange seat upper surface improve sealing of the present utility model.The utility model does not need to dismantle the direction that just can adjust wire-threading device, can guarantee sealing again.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of wire-threading device bump joint of the present utility model;
Fig. 2 is the plan structure schematic diagram of wire-threading device bump joint of the present utility model.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of wire-threading device bump joint, comprise the flange seat 8 that middle part has the first manhole, the below of flange seat 8 is provided with the first straight steel pipe 7 for connecting roof, and the top of flange seat 8 is provided with the flange 6 that bolt 3 is connected with nut 4;
The periphery of flange 6 is provided with at least two bolt perforation, the middle part of flange has second manhole corresponding with the first manhole, the end second manhole being connected with the second straight steel pipe 2, second straight steel pipe 2 is connected with downward opening curve bend 1;
