Flash removed makes it more smooth.
Preferably, described screw rod includes polished rod portion, threaded portion and the guide part being sequentially connected with, described light
Bar portion adjoins described flange portion, away from the periphery of end face in described polished rod portion with described in described threaded portion
The 3rd inclined-plane it is formed with between the periphery of guide part.
Preferably, away from institute between the end face in described polished rod portion in described 3rd inclined-plane and described threaded portion
The angle formed is 45 degree.Use above-mentioned 3rd structure and chamfering 45 degree, and then make this utility model
The column foot flange face bolt provided can be screwed in connected piece swimmingly.
Preferably, described polished rod portion and described flange portion junction are formed with arc surface, described arc surface
Arc radius is 0.065mm-1.035mm.Described polished rod portion uses arc surface to be connected with described flange portion can
To reduce the risk because being made screw rod and flange portion rupture by the effect of shearing force.
Preferably, described nut is regular hexahedron, any two adjacent surfaces on six lateral surface of described nut
Between be equipped with groove.Use and groove is set on each of six outsides of described nut, reduce nut
Volume and weight, save material cost, and decrease the space that nut takies, meanwhile, solid connecting
Regularly, can directly with hands active force in described groove, thus allow column foot flange face bolt rotate, make
Column foot flange face bolt fast and easy must be dismounted.
It addition, this nut is regular hexahedron so that this column foot flange face bolt can by spanner or its
His instrument clamps and pulls, so that active force suffered by column foot flange face bolt is bigger, increases even
Connect intensity.
Preferably, the material of described column foot flange face bolt uses high strength steel.
Preferably, described high strength steel is 42CrMoA.42CrMoA belongs to unimach, has
High intensity and toughness, use the high-strength bolt of superhigh intensity steel making to have simple, stress performance of constructing
Good, replaceable, endurance and the advantage such as will not loosen under dynamic load function.
In this utility model, above-mentioned optimum condition on the basis of meeting common sense in the field can combination in any,
Obtain each preferred embodiment of this utility model.
Positive progressive effect of the present utility model is:
Even if first, using ramp structure narrow space, column foot flange face bolt and surrounding also will not be made
Parts produce interfere；
The second, flange portion is used to increase and the contact surface of connected piece column foot so that this utility model carries
The column foot flange face bolt of confession is combined more firm with connected piece；
3rd, polished rod portion and flange portion use arc surface to be connected the effect that can reduce because of by shearing force to make
The risk that screw rod ruptures with flange portion；
4th, on each of six lateral surface of described nut, use groove structure, reduce nut
Volume and weight, and decrease the space that nut takies, when connecting fixing, can directly use meanwhile
Hands active force is in described groove, thus allows column foot flange face bolt rotate so that dismounting column foot flange face
Bolt fast and easy；It addition, this nut is regular hexahedron so that this column foot flange face bolt can pass through
Spanner or other instruments clamp and pull, so that active force suffered by column foot flange face bolt is more
Greatly, bonding strength is increased；
5th, use the high-strength bolt of superhigh intensity steel making to have construction is simple, stress performance is good,
Replaceable, endurance and the beneficial effect such as will not loosen under dynamic load function.
