Description
[technical field]
The utility model relates to the technical field of flange nut, particularly the technical field of the anti-skidding hexagonal flange nut of a kind of double end.
[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, traditional flange nut has much room for improvement in anticorrosion and non-skid property, in addition existing flange nut is only at one end provided with compressing structure, needs while during fastening two ends, can not play and well seal fastening effect.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, the anti-skidding hexagonal flange nut of a kind of double end is proposed, by being symmetrical arranged the first shim tray, the second shim tray at the two ends of connecting body, can the two ends of simultaneously fastening connection piece, play good seal action.
For achieving the above object, the utility model proposes the anti-skidding hexagonal flange nut of a kind of double end, comprise the connecting body having tapped hole, the two ends of described connecting body are respectively equipped with the first shim tray and the second shim tray, first shim tray and the second shim tray symmetry are installed on the two ends of connecting body, first shim tray and the second shim tray are equipped with 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 connecting body, first shim tray, the surface of the second shim tray and compression plate is equipped with zinc coat, described first shim tray, the thickness of the second shim tray is 1 ~ 3mm, described tapped hole runs through the first shim tray and the second shim tray.
As preferably, described connecting body, the first shim tray, the second shim tray and compression plate are formed in one structure.
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 hemispherical configuration, and the bottom of spot-like projections is plane structure, and described plane structure is provided with taper insection structure.
The beneficial effects of the utility model: the utility model is by being symmetrical arranged the first shim tray at the two ends of connecting body, second shim tray, can the two ends of simultaneously fastening connection piece, play good seal action, and at connecting body, first shim tray, the surface of the second 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, spot-like projections is hemispherical configuration, the bottom of spot-like projections is plane structure, plane structure is provided with the surface of contact that taper insection structure considerably increases compression plate and link and 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.
