Embodiment
Below with reference to accompanying drawings exemplary embodiment disclosed in the utility model is described in more detail.Although show exemplary embodiment disclosed in the utility model in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment that sets forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
As shown in Figure 1 to 4, in an embodiment of the present utility model, provide a kind of flange welding nut 1 with sealing auto-lock function, described flange welding nut 1 comprises: main body portion 2, be positioned at the flange part 3 of main body portion 2 one end and run through the tapped hole 4 of described main body portion 2 and flange part 3, on the excircle of the bottom end face of described flange part 3, axial direction along described tapped hole 4 is provided with the annular welds circle 5 for being welded to connect with welded steel 9, the annular slope 7 that described annular welds circle 5 comprises an annular side 6 and is connected in oblique angle with described annular side 6, the joint of wherein said annular side 6 and described annular slope 7 is provided with fillet, be connected in oblique angle between described annular slope 7 and the bottom end face of described flange part 3, the top of described main body portion 2, the horizontal port 8 of at least one is provided with in the radial direction along described tapped hole 4, described horizontal port 8 runs through the excircle of described tapped hole 4, is positioned at screw thread on the tapped hole 4 of sustained height for be out of shape screw thread with described horizontal port 8.
In the present embodiment, the excircle of flange part 3 bottom end face arranges annular welds circle 5, wherein annular welds circle 5 comprises annular side 6 and annular slope 7, wherein between annular slope 7 and the bottom end face of flange part 3 for oblique angle is connected.At flange welding nut 1 with the welding process of welded steel 9, annular welds circle 5 reduces the weld seam existed between flange welding nut 1 and welded steel 9, ensure that sealing when flange welding nut 1 welds with welded steel 9.
In addition, the horizontal port 8 be arranged on main body portion 2 top of flange welding nut 1 is carried out extruding and form distortion screw thread, in the process that flange welding nut 1 coordinates with bolt, the matching relationship that bolt and horizontal port 8 are positioned at the tapped hole 4 of sustained height becomes interference fit from original Spielpassung, thus make to be not easy to loosen between bolt and flange welding nut 1, reaching flange welding nut 1 can the object of self-locking.
As shown in Figure 3, the radius of the fillet of the joint of annular side 6 and annular slope 7 is 0.9 ~ 1.1cm.
In the present embodiment, be not easy to be collided with and eliminate the annular side 6 of annular welds circle 5 and the stress of annular slope 7 joint to protect people, the connection between annular side 6 and annular slope 7 is that fillet connects, and the radius of fillet is 0.9 ~ 1.1cm.
Continue see Fig. 3, the oblique angle angular range between the bottom end face of annular slope 7 and flange part 3 is 42 ~ 48 degree.
In the present embodiment, by the oblique angle angular range between annular slope 7 and the bottom end face of flange part 3 is limited in 42 ~ 48 degree, ensure that sealing when flange welding nut 1 welds with welded steel 9, also ensure that the welding quality of flange welding nut 1 and welded steel 9 simultaneously.
