Abstract
The utility model provides a kind of double structure stop nut, it is made of two nuts, one of one end is cone boss, another one end is taper concave station, maximum distance of the cone boss front edge from nut center is less than the radius of taper concave station outer end, and cone boss is axially grooved to be divided into two valves or more.Its effect is: 1, nut fastening is stablized, anti-back effect is good, this is the nut equipped with boss just as a chock, it is filled between concave station nut and screw rod, when concave station nut is tightened down, several valves that boss nut boss is slotted, which tightly embrace screw rod, to be loosened, to generate locking anti-back effect.
Description
Technical field: especially a kind of the utility model relates to a kind of improved mechanical part-nut for fastening
The double structure stop nut for preventing it from exiting after nut fastening.
Background technique: nut, because of a variety of causes such as vibrations, is easy to appear nut loosening and exits after fastening a period of time,
So that the phenomenon that fastening failure, causing various Frequent Accidents.To prevent this phenomenon from occurring, existing method mainly has: 1, using
Two plain nuts are screwed on a screw rod proposition for preventing nut simultaneously；2, between screw rod and nut, medium is set, with
Increase the two frictional force or cohesive force to prevent nut from exiting.But above two mode still sends one's regards to topic in use.Though the former
So there is certain anti-back effect, but because being equally two plain nuts, there is no occur big for the effect between nut and screw rod
Variation, so anti-back effect is not too good；The latter because being provided with medium between nut and screw rod, make really screw rod and nut it
Between squeeze enhancing, a possibility that nut exits reduction, but there is also a drawbacks, i.e., very tired when releasing fastening and exiting nut
Difficulty is more difficult when exiting when especially some media are cohesive material.
Summary of the invention: the purpose of this utility model is that, for the existing technological means for preventing nut from exiting after tightening
It is existing insufficient in use, and propose a kind of double structure stop nut, it has anti-back effect good, to exit releasing fastening
It is convenient and simple when nut.
The utility model aim, a kind of double structure stop nut can be realized by following technical proposals, which is characterized in that it
Be made of two nuts, one of one end be cone boss, another one end be taper concave station, cone boss front edge from
The maximum distance at nut center is less than the radius of taper concave station outer end, and cone boss is axially grooved to be divided into two valves or more.
Cone boss and nut are off-centre operation structure.
Cone boss and nut are concentric structure.
To make cone boss Maximum Contact hold screw rod tightly, axially separated cone boss is pintongs.
For the benefit of cone boss divide valve hold tightly screw rod, the root of cone boss is provided with baltimore groove.
The effect of the utility model is: 1, nut fastening is stablized, and anti-back effect is good, this is the nut equipped with boss just
As a chock, it is filled between concave station nut and screw rod, when concave station nut is tightened down, so that boss nut boss is slotted
Several valves can tightly embrace screw rod and will not loosen, to generate locking anti-back effect.
Detailed description of the invention:
Attached drawing 1 is the schematic cross-sectional view (screw rod plays setoff) of the utility model embodiment 1；
Attached drawing 2 is the overlooking structure diagram of nut 2 in attached drawing 1.
Attached drawing 3 is the schematic cross-sectional view (screw rod plays setoff) of the utility model embodiment 2；
Attached drawing 4 is the overlooking structure diagram of nut 2 in attached drawing 3.
The utility model is further described with reference to the accompanying drawings and embodiments:
Specific embodiment:
Referring to attached drawing 1,2, a kind of double structure stop nut, it is made of nut 1 and nut 2.2 one end of nut is that taper is convex
Platform, 1 one end of nut are taper concave station corresponding with cone boss.The radius of cone boss front end is less than the half of taper concave station outer end
Diameter, cone boss and nut 2 are concentric structure.Cone boss is axially grooved to be divided into pintongs.For the benefit of point of cone boss
Valve holds screw rod 3 tightly, and the root of cone boss is provided with baltimore groove 4.
Referring to attached drawing 3,4, a kind of double structure stop nut, it is made of nut 1 and nut 2.2 one end of nut is that taper is convex
Platform, 1 one end of nut are taper concave station.Maximum distance of the cone boss front edge from 2 center of nut is less than taper concave station outer end
Radius.Cone boss and nut 2 are off-centre operation structure.Cone boss is axially grooved to be divided into pintongs.
