Description

Technical Field

[0001] The utility model belongs to the technical field of nuts, in particular to a large-size thin-wall nut fastening component. Background Art

[0002] Nuts are one of the common fasteners. The internal thread of the threaded hole cooperates with the external thread of the bolt or stud (screw pile), and plays a tightening role after screwing together. They are widely used in production and life. The more common nuts fixed on the metal clamped structure are welded nuts or riveted nuts. Welded nuts and riveted nuts are of various types and shapes.

[0003] When fixing thin-walled nuts, the nuts are installed by deformation after being plugged in. However, the deformed nuts cannot be reused, resulting in a waste of resources. In addition, the nuts are more troublesome to disassemble. Therefore, we propose a large-size thin-walled nut fastening assembly. Utility Model Content

[0011] Preferably, positioning grooves are provided on the inner sides of the upper curved piece and the bottom curved piece, and the two groups of positioning grooves are cross-arranged.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By reversing the rotation of the bolt, the nut automatically moves backward, so that the nut automatically drives the folding frame to open, so that the nut body can be better installed and disassembled. When the folding frame is folded, the upper curved piece and the bottom curved piece will automatically move outward on the opposite sides, so that the upper curved piece and the bottom curved piece fit together. The plug-in rod can be provided to limit the position of the upper curved piece and the bottom curved piece, so as to assist the upper curved piece and the bottom curved piece to better fold.
