Description
Technical field
The utility model is related to a kind of handware, and in particular to a kind of locking fastening combination nut.
Background technology
Locking nut is the part to being fixed on the positioning installed in fixed part, possesses locking mechanism, even if being allowed to
Because vibration, the impact of fixed part produce gap between locking nut and fastening face, it will not also loosen.But in high frequency
Above the machinery of vibrations, such as above the plant equipment such as crane machine, engine, generator, wind-power electricity generation, common locking screw
It is female under dither effect, also can be slowly fluff or even comes off.Once generation, which loosens or come off, will trigger serious peace
Full accident.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind by this knockdown nut structure, Neng Gouyou
Coupling mechanism force between effect increase nut and screw rod, effectively plays anti-loose purpose, increase assembling fastening force.
The utility model is achieved through the following technical solutions：A kind of locking fastening combination nut, including mother nut,
The bottom of mother nut is provided with locking section, is integral type structure between mother nut and locking section, and locking section external locking is provided with
One outer nut, the outer wall of the outer nut and mother nut is provided with the polygon facet for spanner clamp, the locking
More than one binding groove is offered in section.
As preferred technical scheme, the locking section outer wall, which is provided with the middle of external screw thread, the outer nut, to be provided with outside
Nut bore, outer nut hole inwall is provided with the internal thread with the external screw thread assembling of locking section.
As preferred technical scheme, mother nut external diameter is less than the external diameter of locking section, and the internal diameter in outer nut hole is more than main spiral shell
Female external diameter is simultaneously equal to the external diameter of locking section, outer nut be set in from top to bottom mother nut upper end and with the locking of mother nut lower end
Section screw-threaded coupling.
As preferred technical scheme, the binding groove is set perpendicular to horizontal plane, and binding groove is provided with four, is arranged at
On the quarterline for locking section.
Offering one as preferred technical scheme, between the mother nut and locking section is used for the lead-over groove of separation.
The beneficial effects of the utility model are：The utility model is simple in construction, passes through this knockdown nut structure, energy
The coupling mechanism force between nut and screw rod is enough effectively increased, anti-loose purpose, increase assembling fastening force is effectively played.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is configuration schematic diagram of the present utility model；
Fig. 2 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
Such as Fig. 1 and Fig. 2, including mother nut 2, the bottom of mother nut 2 is provided with locking section 5, mother nut 2 and locking section 5 it
Between be integral type structure, the locking external locking of section 5 is provided with an outer nut 3, and the outer wall of outer nut 3 and mother nut 2 is respectively provided with
Have and offer more than one binding groove 7 in the polygon facet 4 for spanner clamp, locking section 5.
The locking outer wall of section 5, which is provided with the middle of external screw thread 8, outer nut 3, is provided with outer nut hole, and outer nut hole inwall is provided with
With the internal thread of the locking external screw thread of section 5 assembling, mother nut external diameter is less than the external diameter of locking section, and the internal diameter in outer nut hole is more than main spiral shell
Mother 2 external diameter simultaneously be equal to locking section external diameter, outer nut be set in from top to bottom the upper end of mother nut 2 and with the lower end of mother nut 2
Lock the screw-threaded coupling of section 5.
Binding groove 7 is set perpendicular to horizontal plane, and binding groove 7 is provided with four, on the quarterline for being arranged at locking section 5,
Offering one between mother nut 2 and locking section 5 is used for the lead-over groove 1 of separation.
During installation, mother nut is installed on bolt and tightened, after tightening, then by outer nut from top to bottom through mother nut with
And the external screw thread locking outside the locking section of lead-over groove and lower end, because the internal diameter in outer nut hole is more than the external diameter of mother nut 2 simultaneously
Equal to the external diameter of locking section, therefore any influence will not be produced on the assembling of outer nut, after outer nut is locked with locking section
Complete assembling, additionally, due to being provided with more than one binding groove, therefore coupling mechanism force can be effectively increased so that locking section lower end with
Attachment force between bolt is stronger.
The beneficial effects of the utility model are：The utility model is simple in construction, passes through this knockdown nut structure, energy
The coupling mechanism force between nut and screw rod is enough effectively increased, anti-loose purpose, increase assembling fastening force is effectively played.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
