Abstract
The utility model discloses a convex shoulder flange nut belongs to mechanical technical field, comprises ring flange, connector, nut body, convex shoulder and screw hole, and the design of nut body both sides terminal surface one side has the convex shoulder, and the opposite side design has the ring flange, adds the connector between nut body and the ring flange, the dead in line of ring flange, connector, nut body and convex shoulder, the penetrating screw hole of its axle center department design. The outer terminal surface of ring flange is machining plane, and the convex shoulder is the form that closes up towards the other end on one side of the nut body. This convex shoulder flange nut anufacturability is good, is convenient for manufacture, and manufacturing cost is lower, the convex shoulder can increase the frictional force between nut and the bolt, and the ring flange machined surface is direct to increase its frictional force with the adapting unit contact to improve convex shoulder flange nut's locking effect.
Description
Technical field
This utility model belongs to field of mechanical technique, relates to nut, especially a kind of convex shoulder flange nut.
Background technology
Nut is the part got up by plant equipment compact siro spinning technology, and by the screw thread of inner side, equivalent specifications nuts and bolt just can link together, the more self-locking nut of nut kind, stop nut, locking nut, four paws nut, screw-in nut, lock nut etc..Nut can loosen in vibration environment with bolt connection status, and nut loosening can bring fatal harm to plant equipment, and it is possible to the personal safety of harm operator.Therefore, nut anti-looseness is always the problem of mechanical engineer's research.The reason of nut loosening is more, when general sharp pounding, repetition varying load or operating temperature are higher, the normal pressure on nut rubbing surface there will be momentary loss or reduction easily causes nut loosening, in addition, it is repeated several times and makes the vibration force along nut radial direction promote nut rotation, nut loosening can be caused.
The utility model patent of application number 201220437272.4, open a kind of loose-proof flange nut, including nut body, nut body includes flange portion in the form of a ring and the connecting portion being connected as a single entity with described flange portion, connecting portion offers annular groove on one end of flange portion, the fatigue strength height that loose-proof flange nut is threaded, each several part screw food distribution is uniform, and nut anti-looseness is effective.The use novel flange nut anti-looseness set patent of application number 201320762517.5; including the circular collar; the collar is made up of elastomeric material; the interior side opening of the collar; the collar is provided with the bayonet socket of circular arc, and bayonet socket is provided with padded coaming, flange nut loose-proof sleeve; to bolt anti-loosening effective on flange, can effectively protect the outer surface of flange simultaneously.
The stop nut with flange arrangement disclosed above, improves from nut self structure or by using additional device to send out anti-loosing effect to improve nut.The volume of nut is typically small, is not easy to be processed after one-shot forming, additionally uses other external members to carry out the locking secondary harm of easy initiation in nut.
Utility model content
This utility model is for solving the deficiencies in the prior art, it is provided that a kind of convex shoulder flange nut, solves existing nut and does not have locking functions or the irrational problem of locking measure.
The technical solution of the utility model is as follows:
A kind of convex shoulder flange nut, is made up of ring flange, connector, nut body, convex shoulder and screwed hole.
Nut body is hexagonal structure, and end face side, both sides is designed with convex shoulder, and opposite side is designed with ring flange.For strengthening nut body and ring flange bonding strength, set up connector between the two.
Convex shoulder is column structure, and its axial line overlaps with nut body axis.
Ring flange is column structure, and bottom surface is processing plane, and its axial line overlaps with nut body axis.
Connector is frustum cone structure, and its axial line overlaps with nut body axis；The big nose circle of connector links together with ring flange, and little nose circle links together with nut body.
Blue dish, connector, nut body and convex shoulder constitute an entirety, design penetrating screwed hole at its axle center.
For strengthening the bonding strength of convex shoulder flange nut, and improving its anufacturability, flange thickness is 1.4mm ~ 2mm, and outer face is unilateral, to improve flatness for processing.
After convex shoulder Center screwed hole, unilateral thickness cannot be less than 1mm, highly 5mm ~ 7mm.
As preferably, convex shoulder from nut body side towards the other end be closing in shape, closing in angle 2 ° ~ 5 °.
Convex shoulder flange nut when installing and using, processed after flange face flatness higher, increase the contact area between nut and connection member, under nut pretightning force effect improve frictional force, prevent nut volume loosen；There is the convex shoulder of closing-in structure, on the one hand add the screw thread pair screwing length of bolts and nuts, on the other hand increase the pressure between convex shoulder and bolt, improve the frictional force between nut and bolt.
Effect of the present utility model and benefit be: this convex shoulder flange nut simple in construction, and the anufacturability of convex shoulder and ring flange is good, it is simple to manufacturing, production cost is relatively low；Convex shoulder can increase the frictional force between nut and bolt, and ring flange machined surface directly contacts its frictional force of increase with connection member, thus improves the anti-loosing effect of convex shoulder flange nut.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
A kind of convex shoulder flange nut, as shown in Figure of description 1 and accompanying drawing 2, is made up of ring flange 1, connector 2, nut body 3, convex shoulder 4 and screwed hole 5.The end face side, both sides of nut body 3 is designed with convex shoulder 4, and opposite side is designed with ring flange 1；Connector 2 is set up between nut body 3 and ring flange 1.
Ring flange 1, connector 2, nut body 3 and the dead in line of convex shoulder 4, design penetrating screwed hole 5 at its axle center.
Ring flange 1 and convex shoulder 4 are column structure, and connector 2 is frustum cone structure.Ring flange 1 thickness is 1.4mm ~ 2mm, and outer face is unilateral, to improve flatness for processing.After convex shoulder 4 Center screwed hole, unilateral thickness cannot be less than 1mm, highly 5mm ~ 7mm.
For improving the anti-loosing effect of convex shoulder flange nut, convex shoulder 4 has closing in, closing in angle 2 ° ~ 5 ° from nut body side towards the other end.
Figure of description be only used as the structure of product, principle schematic, actual product structure and size with inventor design production drawing be as the criterion.
Embodiment described above is only to be described embodiment of the present utility model, is not defined spirit and scope of the present utility model.On the premise of without departing from this utility model design concept; various modification that the technical solution of the utility model is made by this area ordinary person and improvement; all should drop into protection domain of the present utility model, scope of the present utility model is limited by claims rather than described above.
