Description
Technical field
The present invention relates to a kind of stop nut.
Background technology
Threaded connection is widely used in plant equipment, but the reason such as equipment vibration, impact in the running is influenced whether
The tightness and reliability of threaded connection.Therefore the locking of threaded connection is just must take into consideration in visual plant and key position to ask
Topic.
Double nuts structure is a kind of locking thread mechanism being most widely used, although its structure is simple, anti-loosing effect
Screw-down torque when being decided by that two nuts are installed, it is higher to installation requirement, will otherwise weaken the locking effect of double nuts structure
Fruit even results in the locking failure of double nuts structure.
If additionally, the size of connection screw thread is larger, very big moment of torsion is accomplished by when installing double nut, installs and be just stranded very much
It is difficult.
The content of the invention
Regarding to the issue above, the present invention provides a kind of simple structure, installs reliable stop nut.
To reach above-mentioned purpose, stop nut of the present invention, including a nut, it is provided with one on the flank of the nut
Annular groove, is provided with an outer groove on the lateral wall of the nut, the inner groove basal diameter is straight more than the outer shroud groove bottom
Footpath；The midfeather of the inner groove and the axially spaced setting of the outer groove, the outer groove and the inner groove is change
Shape section, the both sides of the inner groove are respectively preceding thread section and rear thread section；The front end face of the nut is provided with an anti-porosity,
The anti-porosity runs through the inner groove and the outer groove.
Further, the part of anti-described locking section of the porosity correspondence is unthreaded hole, described to loosen the hole correspondence cooperation
The part of section is screwed hole.
Further, the basal diameter of the inner groove is straight with the anti-porosity more than the reference diameter of the anti-porosity
Footpath sum；The inner groove basal diameter is more than the outer groove basal diameter；
And/or,
The basal diameter of the outer groove is less than the reference diameter of the anti-porosity and the difference of the locking bore dia；Institute
Inner groove basal diameter is stated more than the outer groove basal diameter.
Further, the opening of outer groove is provided with a sealing ring, and the sealing ring is matched somebody with somebody with outer shroud channel opening sealing
Close.
Further, deformation section thickness vertically is 1-5mm.
Further, less than the diameter of the cooperation section, each anti-porosity is along the nut for described locking section of diameter
Circumference be uniformly distributed.
Further, the outer groove is arranged on the front side of the inner groove.
When stop nut of the present invention is installed, rear side is first screwed in, and after being installed in place, then inserts screws into nut anterior end surface
In anti-porosity.During screw-driving, when screwing force is reached to a certain degree, can make between inside and outside two groove in nut
When partly (L sections) deforms, a left side for the left surface of front side threaded portion ridge and connecting bolt ridge on nut inner ring
Surface compresses, and the right surface of rear side threaded portion ridge compresses with the right surface of connecting bolt ridge on nut inner ring, this
Sample is achieved that the locking of nut.
Additionally, stop nut of the present invention is an entirety, will not be relatively rotated between two sections of internal threads before and after nut,
So as to improve locking reliability when nut is subject to impact shock at work.
Stop nut anti-loosing effect of the present invention is good, simple structure, without to control to tighten torsion as double nuts structure during installation
The size of square, install convenient, required moment of torsion is small during locking, it is adaptable to the threaded connection of big specification.
Brief description of the drawings
Fig. 1 is the sectional view of the embodiment 1 of stop nut of the present invention；
Fig. 2 is enlarged drawing at the I of Fig. 1；
Fig. 3 be stop nut of the present invention embodiment 1 install after thread pitch schematic diagram.
Specific embodiment
With reference to Figure of description, the present invention will be further described.
" preceding " in the present invention refers to that " afterwards " refers to by nut away from by the side of fastening workpiece after nut fastening is finished
Fastening is close to by the side of fastening workpiece after finishing；The reference circle that anti-porosity in the present invention is refer to the center of circle of nut be circle
The heart, in case the circle that the distance between the porosity center of circle and nut center of circle are formed by radius.
Embodiment 1
As Figure 1-3, the present embodiment provides a kind of stop nut；As shown in figure 1, the present embodiment stop nut is at least wrapped
Include screw 1, dust ring 2 and nut 3.Wherein, screw 1 coordinates with the anti-porosity of the anterior end surface of nut 3, for locking nut；It is anti-
Konisphere 2 is arranged on the groove on the outer ring of nut 3, for preventing dust and other impurities from falling into the groove, so as to influence nut just
Often use.
On the outer ring of nut 3, there are a groove, groove diameter B near front side；On the inner ring of nut 3, have one recessed near rear side
Nut inner thread is divided into front and rear two sections by groove, groove diameter C, groove, and the distance between inside and outside two grooves are L.

Can not be excessive apart from L, otherwise nut 3 be difficult to it is locking, or even cannot be locking；L sections in the present embodiment of thickness is taken as 1mm.
The centre of nut 3 is tapped through hole, and several anti-porosities are evenly distributed with the anterior end surface circumferencial direction of nut 3.
The form of anti-porosity is：With inner ring groove as boundary, inner ring groove front side is circular hole, and aperture is more than screw diameter；Outer ring groove
Rear side is screwed hole, and thread size D, screw thread hole depth will take into full account the length and stroke of screw, screwed hole reference diameter A.
Screw 1 coordinates with the anti-porosity of the anterior end surface of nut 3, for locking nut.
Dust ring 2 is arranged on the groove on the outer ring of nut 3, for preventing dust and other impurities from falling into the groove, so that shadow
The normal of nut is rung to use.
When the present embodiment stop nut is installed, nut 3 is screwed in from rear side, after being installed in place, then screw 2 is screwed into spiral shell successively
In the screwed hole of female 3 anterior end surfaces.In the rundown process of screw 1, the part (L between inside and outside two groove in nut 3 can be made
Section) when deforming, the preceding surface of front side threaded portion ridge is pressed with the preceding surface of connecting bolt ridge on the inner ring of nut 3
Tightly, the right surface of rear side threaded portion ridge compresses with the right surface of connecting bolt ridge on the inner ring of nut 3, thus real
The locking of nut 3 is showed.
