Abstract

The invention provides a flange nut washer assembly to solve the problem of inconvenient operation when the flange nut and the washer are installed separately. The flange nut washer assembly includes a flange nut and a washer coaxially arranged, one end face of the washer is attached to the flange end face of the flange nut, and the end of the washer away from the flange nut is provided with an outer chamfer, The flange nut washer assembly also includes a clip-type structure for preventing axial relative displacement of the flange nut and the washer, and the clip-type structure includes a first pressing portion and a pressing portion for pressing the annular skirt of the flange nut. Tighten the second pressing part of the outer chamfer of the washer. The first pressing part and the second pressing part of the clip-type structure produce an axial clamping force on the flange nut washer assembly, so that the washer and the flange nut will not have axial relative displacement, so that the washer is fixed on the flange on the flange end of the nut. When installing, flange nuts and washers can be installed together for easy operation.

Description

technical field [0001] The invention relates to a fastener, in particular to a flange nut washer assembly. Background technique [0002] Nuts and washers usually form fasteners together with bolts. The bolts pass through the connecting piece and the connected piece, and the other end is put on the washer, and then the nut is connected. The connecting piece and the connected piece are tightly assembled through the threaded connection of the nut and the bolt. In mechanical fastening connections, the installation sequence is usually to install the washer first, then screw on the nut, and the nut is pressed against the washer. However, when the installation space is small, it is inconvenient for hands to enter; or when the washer and nut need to be installed on the back, press the washer with one hand, and assemble the nut with the other hand. A washer and nut would take a long time and work less efficiently. As a kind of nut, the flange nut also has this problem. Such as fi...
