Abstract
The utility model discloses a kind of stop nut based on circular cone EDS maps screw thread, including nut main body, the screwed hole of the nut main body is the conical through-hole with certain taper, and the screw thread in the screwed hole is along the circular cone EDS maps with certain taper.The utility model can provide a kind of stop nut with good anti-loosing effect on the premise of occupation mode is not changed substantially, the size of screw gradually tapers up, with nut due to mutually extruding deformation to a certain degree will occur for screw, pressure between screw and nut on contact surface gradually increases, and then the frictional force between screw and nut is gradually increased, so as to reach preferable anti-loosing effect.
Description
Technical field
The utility model provides a kind of based on stop nut of the screw thread along circular cone EDS maps, can dramatically avoid spiral shell
Female situation about being loosened after tightening, belongs to machanical fastener field.
Background technology
Screw and nut are the conventional fasteners of all trades and professions, and mounted screw, nut are easily due to vibrations, external force punching
The factor sounding such as hit to loosen or even release, cause fastening to be failed, and then plant equipment is broken down, cause damage.City at present
Generally there is stop nut on face complicated, nut to be fastenedly connected the problems such as process is more, dismounting maintenance is inconvenient, not even
Can recycling.The utility model provide it is a kind of can largely avoid above mentioned problem based on simple and mechanical structure, i.e.,
Screw thread is distributed in circular conical surface by improving, to reach the frictional force between increase nut, screw, reach locking effect.
Utility model content
In order to dramatically avoid the nut tightened using among process due to the factors such as vibrations occur to loosen so as to
Have a strong impact on the stability of associated mechanical structure, the utility model provide it is a kind of can be after tightening from the new anti-of primary lock
Loose nut.Can be widely used among daily life, particularly it is some for security requirement it is high, need to use screw
In the mechanical structure of nut.The nut for dramatically avoiding tightening is among using process because the factors such as vibrations loosen
So as to have a strong impact on the stability of associated mechanical structure,
Originally make the technical scheme of utility model as follows：
A kind of stop nut based on circular cone EDS maps screw thread, including nut main body, the screwed hole of the nut main body are
Conical through-hole with certain taper, screw thread in the screwed hole is along the circular cone EDS maps with certain taper.
Further, described nut main body side is provided with the identifier for indicating that screw is screwed into direction.
Further, described identifier is arrow.
Further, described arrow points to small end by the big end of screwed hole.
Further, the taper of the screwed hole is 0o＜ θ≤8o。
Further, the material of the described nut main body includes metal or engineering plastics.
Gain effect of the present utility model is to provide one kind on the premise of occupation mode is not changed substantially to have well
The stop nut of anti-loosing effect, the size of screw gradually taper up, and screw will occur to a certain degree with nut due to mutually extruding
Deformation, the pressure between screw and nut on contact surface gradually increase, and then make it that the frictional force between screw and nut is gradual
Increase, so as to reach preferable anti-loosing effect.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model embodiment.
Fig. 2 is the schematic perspective view of the utility model embodiment.
Embodiment
Purpose of utility model of the present utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings,
Embodiment can not repeat one by one herein, but therefore embodiment of the present utility model is not defined in following examples.
As depicted in figs. 1 and 2, a kind of stop nut based on circular cone EDS maps screw thread, including nut main body, the nut
The screwed hole of main body is the taper hole with certain taper, and the screw thread in the screwed hole is along the circular conical surface point with certain taper
Cloth, the taper of the screwed hole is 0o＜ θ≤8o, angle is too small, does not have the effect of extruding locking, can then influence nut greatly very much
With the connecting length of screw rod.
Specifically, described nut main body side is provided with the identifier for indicating that screw is screwed into direction, the identifier
For arrow, described arrow points to small end by the big end of screwed hole.
The material of the nut main body includes metal or engineering plastics,
The present embodiment provide one kind can high degree avoid tightening nut in use due to factors such as vibrations
The arrow that instruction screw is screwed into direction is carved with the stop nut loosened, its outside, and screw must be along the direction of the arrow
It is screwed into nut；Screw thread on nut screw is along a circular cone EDS maps with certain taper, i.e. screw is a taper hole, root
According to the direction of arrow on the outside of nut, screw is screwed into from the larger side of hole, is back-outed from the smaller side of hole, as screw is gradually twisted
Enter, the size of screw gradually tapers up, and due to mutual extruding deformation to a certain degree will occur for screw and nut, screw and nut it
Between pressure on contact surface gradually increase, and then the frictional force between screw and nut is gradually increased, it is preferable so as to reach
Anti-loosing effect.
Existing stop nut is different from, the internal thread of the stop nut of the present embodiment uses cone inclined EDS maps rather than biography
The cylinder EDS maps of system, i.e. screwed hole are the through holes of a reduced diameter.Screw is screwed into from macropore side, from aperture side
Back-out.For the diameter of macropore depending on nut specification, concrete numerical value determination mode is identical with conventional nut；The diameter of aperture is then small
It is a circular conical surface with certain taper between macropore, two holes.With screw, from macropore side, rotation is screwed into, due to spiral shell
Female screwhole diameter is gradually reduced, and the frictional force between screw and nut on contact surface gradually increases, so as to reach locking effect
Fruit.Meanwhile the arrow that aperture side is pointed to from macropore side is carved with the outside of nut, i.e.,：The direction of arrow is the direction that screw is screwed into.
The stop nut is used as manufacture material using spring steel, carbon steel, stainless steel, steel alloy, copper etc., has good plasticity.Use
Person in use can be different degrees of so as to reach according to the different nuts for needing circular conical surface taper where selecting screw thread different
Anti-loosing effect.Under normal circumstances, circular conical surface taper where screw thread is bigger, and its anti-loosing effect is relatively stronger, but installing/dismounting
It is more troublesome；Conversely, circular conical surface taper where screw thread is smaller, its anti-loosing effect is relatively weaker, but installing/dismounting is simpler.It can be seen that
This kind of stop nut has good practicality and applicability.
Above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and is not
Restriction to embodiment of the present utility model.For those of ordinary skill in the field, on the basis of described above
On can also make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.
All made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., should be included in this reality
Within new scope of the claims.
