Description
Technical field
The utility model relates to nut part field more particularly to a kind of hexagonal flange nut parts.
Background technique
With the development of science and technology, mechanical equipment is increasingly common in life and production, one by one between mechanical equipment
The effect of nut is can't do without in connection, especially on some heavy mechanical equipments, since plant capacity is big, caused by vibration to rising
Nut to fastening effect plays very big impact, and nut needs very strong antiwear property, tightening additionally, due to nut
Outer surface is prone to wear in journey, is difficult to reach optimum state when causing nut dismounting or reinforcing next time.
Summary of the invention
To solve the above-mentioned problems, it is good, anti-to provide wear-resistant one kind, long service life, fastening effect for the utility model
The hexagonal flange nut of skidding.
The technical solution of the utility model includes: a kind of hexagonal flange nut, including nut body and internal screw thread, nut body
Internal screw thread tooth bottom is equipped with a tapered ramp, and the angle between the tapered ramp and internal screw thread lower plane reverse extending line is
30 °, the cusp tip on the internal screw thread is 60 °, and the nut body includes main nut, secondary nut and flange face, the main spiral shell
Female to be fixedly connected with secondary nut, the pair nut is fixedly connected with flange face, and the main nut is equipped with protective case, the pair spiral shell
Female outer surface is equipped with a convex block.
By adopting the above technical scheme, since the angle between tapered ramp and internal screw thread lower plane reverse extending line is 30 °,
Cusp tip is 60 ° on internal screw thread, such structure be applied to after nut is tightened between screw thread contact caused by normal force with
Axis is at 60 °, rather than 30 ° as regular screw threads, such screw thread normal force greatly increases, so that between bolts and nuts
Frictional force increase, play anti-loosing effect, meanwhile, on main nut be arranged protective case can preferably protect one in equipment
A little important and not easy to disassemble hexagonal flange nuts can play the role of protecting hexagonal flange nut in this way, increase hexagonal method
The service life of blue nut, in addition, being provided with a convex block on secondary nut, convex block can help hexagonal flange nut some
It is more convenient in narrow space fastener cycle.
The further setting of the utility model: the tapered ramp includes upper and lower surfaces, upper surface and lower surface
Between angle be 60 °.
By adopting the above technical scheme, since the angle between the upper surface of tapered ramp and lower surface is 60 °, six
After the fastening of angle flange nut, frictional force is larger, can play good anti-loose effect.
The further setting of the utility model: the length of the convex block is 1cm, is highly 1cm, width 2cm.
It by adopting the above technical scheme, is highly 1cm, the volume of width 2cm, convex block are big since the length of convex block is 1cm
It is small moderate, therefore in some narrow space fastener cycles, very big fastening force can also be added on convex block, so that hexagonal method
Blue nut is closely mounted on bolt, while the volume of convex block will not influence the installation of other part.
The further setting of the utility model: the protective case is hexagon, the internal diameter of the protective case and main nut
Outer diameter size is identical, and the inner surface of protective case is equipped with non slip surface, and the protective case is detachably arranged on main nut.
By adopting the above technical scheme, due to the shape of protective case be also hexagon and protective case internal diameter and main nut it is outer
Diameter size is identical, therefore protective case can be closely joined together with main nut, simultaneously as being equipped in protective case inner surface anti-
Sliding surface, it is ensured that protective case will not fall off from main nut, in addition, since protective case is to be detachably arranged in main nut
On, when protective case abrasion, in the case where some hexagonal flange nuts are less susceptible to disassembly, it is only necessary to dismantle protective case, more
Changing a new protective case can continue to play the role of protecting hexagonal flange nut.
Detailed description of the invention
Attached drawing 1 is a kind of structural schematic diagram of hexagonal flange nut of the utility model specific embodiment.
Attached drawing 2 is the structural schematic diagram of internal screw thread on a kind of hexagonal flange nut of the utility model.
Attached drawing 3 is a kind of structural schematic diagram in face hexagonal flange nut A of the utility model.
Specific embodiment
1-3 as shown in the figure, a kind of hexagonal flange nut, including nut body 1 and internal screw thread 2, the internal screw thread 2 of nut body
Tooth bottom is equipped with a tapered ramp 3, and the angle between 2 lower plane reverse extending line of the tapered ramp 3 and internal screw thread is
30 °, the cusp tip on the internal screw thread 2 is 60 °, and the nut body 1 includes main nut 4, secondary nut 5 and flange face 6, described
Main nut 4 is fixedly connected with secondary nut 5, and the pair nut 5 is fixedly connected with flange face 6, and the main nut 4 is equipped with protective case
7, pair 6 outer surface of nut is equipped with a convex block 8.
Since the angle between 2 lower plane reverse extending line of tapered ramp 3 and internal screw thread is 30 °, cusp tip on internal screw thread 2
Be 60 °, such structure be applied to after hexagonal flange nut is tightened between screw thread 2 contact caused by normal force and axis at
60 °, rather than as 30 ° regular screw threads 2, such 2 normal force of screw thread greatly increases, so that between bolts and nuts 1
Frictional force increases, and plays anti-loosing effect, meanwhile, protective case 7, which is arranged, on main nut 4 can preferably protect one in equipment
A little important and not easy to disassemble hexagonal flange nuts can play the role of protecting hexagonal flange nut in this way, increase hexagonal method
The service life of blue nut, in addition, being provided with a convex block 8 on secondary nut, convex block 8 can help hexagonal flange nut one
It is more convenient in a little narrow space fastener cycles.
The tapered ramp 3 includes upper surface 9 and lower surface 10, and the angle between upper surface 9 and lower surface 10 is 60 °.
Since the angle between the upper surface 9 and lower surface 10 of tapered ramp 3 is 60 °, in hexagonal flange nut
After fastening, frictional force is larger, can play good anti-loose effect.
The length of the convex block 8 is 1cm, is highly 1cm, width 2cm.
It is highly 1cm, the volume of width 2cm, convex block 8 are of moderate size, therefore one since the length of convex block 8 is 1cm
In a little narrow space fastener cycles, very big fastening force can also be added on convex block 8, so that hexagonal flange nut is closely pacified
On bolt, while the volume of convex block 8 will not influence the installation of other part.
The protective case 7 is hexagon, and the internal diameter of the protective case 7 and the outer diameter size of main nut 4 are identical, protective case 7
Inner surface be equipped with non slip surface, the protective case 7 is detachably arranged on main nut 4.
Since the shape of protective case 7 is also that hexagon and the internal diameter of protective case 7 and the outer diameter size of main nut 4 are identical, because
This protective case 7 can be closely joined together with main nut 4, simultaneously as it is equipped with non slip surface in 7 inner surface of protective case, it can be with
Guarantee that protective case 7 will not fall off from main nut 4, in addition, working as guarantor since protective case 7 is detachably arranged on main nut 4
When sheath 7 is worn, in the case where some hexagonal flange nuts are less susceptible to disassembly, it is only necessary to dismantle protective case 7, replace one
New protective case 7 can continue to play the role of protecting hexagonal flange nut.
