Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the technical field of fasteners, in particular to the technical field of flange nuts.
[ background of the utility model ]
Flange nuts, also known as cushion nuts, flower tooth nuts, hexagonal flange face nuts, flange nuts and the like are mostly used for pipeline connection or workpieces needing to increase the contact surface of the nut. The flange nut and the general hexagonal nut have the same size and thread specification basically, but compared with the hexagonal nut, the gasket and the nut are integrated, so that the surface area contact of the nut and a workpiece is increased, and compared with the combination of a common nut and a gasket, the flange nut is firmer and has larger pulling force.
The existing flange nut has the defects of poor wear resistance and easy looseness, and the service life of the nut is shortened.
[ Utility model ] content
The utility model aims to solve the problems in the prior art and provides a wear-resistant flange nut which has good wear resistance and ensures the connection tightness of the nut.
In order to achieve the purpose, the utility model provides a wear-resistant flange nut which comprises a nut body, wherein an integrated flange plate is arranged at the bottom end of the nut body, a threaded hole is formed in the center of the nut body, anti-skidding teeth are uniformly and annularly arranged on the bottom surface of the flange plate, a fastening groove is formed in the side surface of the nut body and is communicated with the threaded hole, a wedge block is arranged in the fastening groove, the fastening groove is matched with the shape of the wedge block, one end of the head part, with a small size, of the wedge block is arranged in the threaded hole, the tail part, with a large size, of the wedge block protrudes out of the outer side of the nut body, a protective coating is arranged on the outer surface of the nut body, and the protective coating sequentially comprises a reinforcing layer, a corrosion-resistant layer, a flame-retardant layer and a wear-resistant layer from inside to outside.
Preferably, the flange plate is uniformly provided with a plurality of fastening through holes in a surrounding manner.
Preferably, the wear-resistant layer is a tungsten-cobalt alloy layer.
Preferably, the tail of the wedge-shaped block is provided with a clamping groove.
The utility model has the beneficial effects that: according to the utility model, the fastening groove and the wedge-shaped block are arranged, and after the bolt is installed, the connection between the bolt and the nut is strengthened by installing the wedge-shaped block, so that the bolt is prevented from loosening; the protective coating is arranged, so that the wear resistance of the nut is enhanced, and the service life of the nut is prolonged; set up fastening through-hole, strengthen the connection fastening nature between nut and the installed part, prevent that the nut is not hard up.
The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.
