Double-end anti-skid hexagon flange nut

Abstract

The invention discloses a double-end anti-skid hexagon flange nut which comprises a connection body with a threaded hole. The two ends of the connection body are provided with a first gasket disc and a second gasket disc respectively. The first gasket disc and the second gasket disc are symmetrically arranged at the two ends of the connection body. Both the first gasket disc and the second gasket disc are provided with pressing discs. The pressing discs are provided with a plurality of arc-shaped protruding blocks. The arc-shaped protruding blocks are provided with protruding insections. A plurality of point-shaped protrusions are arranged between every two adjacent arc-shaped protruding blocks. The surfaces of the connection body, the first gasket disc, the second gasket disc and the pressing discs are provided with galvanized layers. The thickness of the first gasket disc and the second gasket disc ranges from 1 mm to 3 mm. The threaded hole penetrates through the first gasket disc and the second gasket disc. According to the double-end anti-skid hexagon flange nut, the two ends of the connection body are symmetrically provided with the first gasket disc and the second gasket disc respectively, the two ends of the connection piece can be fastened at the same time, and a good sealing function is achieved.

Description

【Technical Field】 [0001] The invention relates to the technical field of flange nuts, in particular to the technical field of a double-headed anti-skid hexagonal flange nut. 【Background technique】 [0002] Flange nuts, also known as pad nuts, spline nuts, hexagonal flange nuts, flange nuts, etc., are mostly used in pipe connections or workpieces that require increased nut contact surfaces. The size of flange nut and general hex nut is basically the same as the thread specification, but compared to hex nut, it is a one-piece gasket and nut, and there are anti-skid teeth underneath, which increases the nut and workpiece Compared with the combination of ordinary nut and washer, it is stronger and more tensile. The flange nut on the oil pipeline often comes into contact with organic liquids. The traditional flange nut needs to be improved in terms of anti-corrosion and anti-skid performance. In addition, the existing flange nut only has a compression structure at one end, which can ...

AI Technical Summary

Problems solved by technology

Flange nuts on oil pipelines are often in contact with organic liquids. Traditional flange nuts need to be improved in terms of anti-corrosion and anti-skid performance. In addition, the existing flange nuts only have a compression structure at one end, which can be tightened at the same time when necessary. When the two ends are fixed, it cannot play a good sealing and fastening effect.
