Description
[technical field]
The utility model relates to the technical field of a kind of hexagonal flange nut in the technical field of flange nut, particularly oil transport pipeline.
[background technique]
Flange nut, also claims band pad nut, flower teeth nut, hexagon nut with flange, flange nut etc., is mostly used in pipeline and connects or need to increase on the workpiece of nut surface of contact.Flange nut is substantially identical with screw thread specification with general hexagon nut size, only compare than hexagon nut, it is pad and nut is integral type, and have anti-skidding groove below, which increase the surface area contact of nut and workpiece, compare the combination that plain nut adds packing ring, more firmly and pulling force larger.Flange nut on oil transport pipeline often contacts with organic liquid, and traditional flange nut has much room for improvement in anticorrosion and non-skid property.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of hexagonal flange nut is proposed, by in mounting head, the surface of shim tray and compression plate is equipped with zinc coat, hexagonal flange nut is made to have good antiseptic property, working life is longer, compression plate is provided with some arc-shaped protrusions blocks, arc-shaped protrusions block is provided with projection groove, some spot-like projections are provided with between two adjacent arc-shaped protrusions blocks, the surface of contact considerably increasing compression plate and link connects, there is good non-skid property, strengthen tightness between the two, better can adapt to the particular surroundings of oil transport pipeline.
For achieving the above object, the utility model proposes a kind of hexagonal flange nut, comprise mounting head, shim tray and compression plate, described mounting head, shim tray and compression plate are structure as a whole, shim tray is between mounting head and compression plate, tapped through hole is had in described mounting head, tapped through hole runs through shim tray and compression plate, described compression plate is provided with some arc-shaped protrusions blocks, described arc-shaped protrusions block is provided with projection groove, some spot-like projections are provided with between two adjacent arc-shaped protrusions blocks, described mounting head, the surface of shim tray and compression plate is equipped with zinc coat.
As preferably, the thickness of described shim tray is 1 ~ 3mm, and the upper end size of described shim tray is less than the lower end size of shim tray.
As preferably, the thickness of described compression plate is 0.5 ~ 1.5mm, and the described height of arc-shaped protrusions block flushes with the height of spot-like projections.
As preferably, described spot-like projections is hemisphere face projection block, and be provided with 3 ~ 5 spot-like projections between two adjacent arc-shaped protrusions blocks, some spot-like projections equally distribute.
The beneficial effects of the utility model: the utility model is by being equipped with zinc coat on the surface of mounting head, shim tray and compression plate, hexagonal flange nut is made to have good antiseptic property, working life is longer, compression plate is provided with some arc-shaped protrusions blocks, arc-shaped protrusions block is provided with projection groove, some spot-like projections are provided with between two adjacent arc-shaped protrusions blocks, the surface of contact considerably increasing compression plate and link connects, there is good non-skid property, strengthen tightness between the two, better can adapt to the particular surroundings of oil transport pipeline.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
