Abstract
The utility model discloses a weld nut which comprises a weld nut body, wherein the body is provided with internal screw thread, weld surfaces are positioned at the two sides of the body, and annular convex areas are positioned on the weld surfaces. By utilizing the utility model, the connecting surface between the weld nut and a conduit is increased, meanwhile, sealing property between the weld nut and the conduit is enhanced, and the welding point formed after welding is larger than the previous point, thereby the firm strength of the welding is greatly enhanced.
Description
Technical field
The utility model relates to a kind of welded nut.
Background technique
Some special pipeline connects in the engineering can use welded nut, replaces not having spendable adapter model.Between pipeline and welded nut, link together by electric welding.Existing welded nut only is applicable to sheet material class face of weld, and it has two parallel face of weld, and the centre is provided with internal thread.Therefore can produce enough big face of weld after the welding on the panel, thereby guarantee the soundness of welding.When this type of welded nut applies on the pipeline, because the face of weld that the weld of welded nut is very smooth so welding finally can produce is the line contact of annular just, the less junction surface of pipeline and welded nut that causes of bonding area is little, thereby the mechanical property of weld is well below requirement of engineering, firmly low, the poor sealing performance of intensity.
The model utility content
The technical problems to be solved in the utility model provides a kind of welded nut, is welded on enough and junction surface tube contacts can be provided behind the pipeline.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: welded nut comprises the welded nut body, and described body is provided with internal thread, and described body both sides are provided with face of weld, and described face of weld is provided with annular projection.
As a kind of improvement of the present utility model, described internal thread extends to the annular projection inboard.
As another kind of improvement the of the present utility model, the described annular projection outside is provided with the flange around annular projection.
As another kind of improvement the of the present utility model, described face of weld is uneven.
The utility model adopts technique scheme, in the junction surface that increases welded nut and pipeline, also promoted the sealability between welded nut and the pipeline, and therefore the soldering point that welding back forms big than in the past improved the firm intensity of welding greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the stereogram of a kind of welded nut of the utility model;
Fig. 2 is the user mode figure of a kind of welded nut of the utility model.
Embodiment
As shown in Figure 1, the body 1 of welded nut is provided with a screw 5, and screw 5 inside are provided with internal thread 2; Two ends be provided with face of weld 3 at body about in the of 1, a face of weld 3 is provided with annular projection 4 therein, and the external diameter size of annular projection 4 is consistent with the internal diameter size of pipeline 7.
As shown in Figure 1, 2, the internal thread 2 of screw 5 extends to annular projection 4 inboards always, be provided with a lot of tiny flanges 6 in the outside of annular projection 4, because annular projection 4 is directly to insert pipeline 7 inside when welding, so form clearance seal between annular projection 4 and the pipeline 7 after welded nut connects, clearance seal can provide the liquid sealing level other sealing effect for pipeline 7.Thereby guaranteeing has sufficient junction surface between welded nut and the pipeline 7, and the sealing function of superior performance is provided simultaneously.
As shown in Figure 1, 2, face of weld 3 is uneven very rough, and these jogs make the area of face of weld increase, and can adsorb more scolder 8, make between pipeline 7 and the welded nut be connected more firm.
