Preferably, the first gasket is in interference fit with the assembly notch and is in clearance fit with the nut body, and the fit clearance is 4-5 mm.

Preferably, the upper edge and the lower edge of the outer wall of the first gasket are provided with convex limiting strips.

Preferably, the lower end of the nut body is integrally formed with a bottom plate, and the bottom plate is located below the assembling seat.

Preferably, a plurality of welding spots are arranged at the bottom of the welding edge.

Preferably, the upper end face of the pressure point is a plane, and the lower end face of the pressure point is an arc-shaped face.

Compared with the prior art, the utility model discloses a combination formula weld nut has following beneficial effect:

the nut body is not directly welded with a workpiece by arranging the assembling seat, so that the material of the nut body is not limited, and the mechanical property of the nut body can be ensured;

the nut body is clamped in the assembling seat through one gasket and is tightly pressed from the upper part through the other gasket, so that the nut body is stably installed on the assembling seat, and the problem that the gasket is deformed to cause failure or cannot be assembled is solved by adopting a clearance fit mode in consideration of the special property of the material of the gasket;

set up the pressure point above the nut body and come to spacing to clearance fit's packing ring, and set the pressure point to the structure of arc under the flat upper portion.

Nut body and first packing ring adopt clearance fit for the nut body can have a little displacement in first packing ring, thereby satisfies the lower fitting piece of precision and in the assembly, finely tunes the alignment, promotes the assembly smooth and easy nature.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-5, the utility model discloses a modular welding nut, including assembly seat 1, nut body 2, first packing ring 3 and second packing ring 4, an assembly opening 5 has been seted up on the assembly seat, and the nut body clamps in the assembly opening through the cover at its outside first packing ring, and the second packing ring cover is established at nut body top to be located first packing ring top, second packing ring and nut body clearance fit, and carry out the axial spacingly through a plurality of pressure points 6 that nut body top set up all around.

Specifically speaking, the lower end of the nut body is integrally formed with a bottom plate 7, the periphery of the upper end is provided with pressure points at intervals, the upper end face of each pressure point is a plane, the lower end face of each pressure point is an arc-shaped face, the arrangement of the pressure point structure can realize the limiting of the second gasket, and the bottom plate arranged at the lower end of the nut body is located below the assembling seat after being assembled to play a role in limiting the lower end.
