Abstract
The utility model belongs to the technical field of the nut technique and specifically relates to a locking nut, it includes the nut body, the nut body be standard size, insidely to the nut body exert certain pressure and form this screw in among a small circle central salient to the nut body a plurality of the going up among a small circle of a certain of the wherein one end of nut body or spaced. The utility model relates to a locking nut, its through nut one end among a small circle in deformation and realize closely cooperating between nut and the bolt, difficult emergence drops, the not hard up condition, improves the performance of nut.
Description
Technical field
This utility model is related to nut technical field, especially a kind of stop nut.
Background technology
Nut general at present is all standard component, its with bolt engagement process in need using elastomeric element increase both it
Between pressure, and then the extruding force being lifted between screw thread and screw thread realizes fastening between the two, and loosening situation does not occur.
Utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology and to provide a kind of structure simple stop nut,
It can effectively realize the steady pressure producing when nut itself is coordinated with bolt so that nut can be firmly fixed to bolt
On, it is not susceptible to loosen.
In order to achieve the above object, the stop nut designed by this utility model, it includes nut body, described nut
Body is standard size；In multiple small ranges at some or the interval of wherein one end of nut body to nut body in
The screw thread that portion applies certain pressure and forms this small range protrudes to the center of nut body.
Technique scheme, a small range in one end of threaded body applies certain pressure, causes in the range of this
Screw thread inside threaded body is inwardly projecting, and causes to be smaller than remaining between the screw thread in the diametric(al) in this region
The spacing between screw thread in region.And in use, when nut body is coordinated with screw rod, this small range after pressurized
Interior screw thread is coordinated with the screw thread on screw rod, because this small range occurred deformation, then can make between the screw thread in this region
Cooperation when the stable extruding force that produces so that coordinating between the two firmly, closely, be not susceptible to loosening situation.
The deflection of the screw thread of above-mentioned a small range is less than or equal to the 20% of thread height.Preferably, its deflection is
The 5-15% of thread height.
The nut body outer surface applying pressure one end is provided with an arc groove or is ringwise arranged at intervals with
Multiple arcs groove, the thickness of the described region inner nut body of arc groove is less than the thickness of the nut body in remaining region
Degree；Apply stressed small range region to be then located inside corresponding arc groove.The design of this structure can effectively make to apply
The side wall of the nut body of a small range of pressure is relatively thin, thus only occurring in this small range in applying press process
Deformation, does not result in whole nut body and changes in circularity, and then can ensure the normal usage energy of nut body.
It is provided with the conical surface, and the region at conical surface place in the nut body outer surface being provided with arc groove one end, spiral shell
The thickness of female body end is minimum；Described arc groove is partially or fully located in the regional extent that the conical surface is located.This conical surface
The design of structure, can preferably realize opening up arc groove in the appearance of nut body, conveniently it is processed, it is possible to decrease plus
Work cost, and do not affect serviceability.
The quantity of described arc groove is six, and each arc groove is arranged at six of nut body outer surface
End corresponding to plane.
Small range in wherein one or two or three arc grooves of six arc grooves applies pressure and causes
Deformation.
Stop nut obtained by this utility model, the deformation of its a small range by nut one end and realize nut with
Tight fit between bolt, is not susceptible to the situation coming off, loosening, improves the serviceability of nut.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model.
Specific embodiment
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1:
As shown in Figure 1 and Figure 2, the stop nut of the present embodiment description, it includes nut body 1, described nut body 1
For standard size；In multiple small ranges at some or the interval of wherein one end of nut body 1 to nut body 1 inside
The screw thread applying certain pressure and forming this small range protrudes to the center of nut body 1.The screw thread of above-mentioned a small range
Deflection is the 5% of thread height.
One arc groove 3 or ringwise interval setting are provided with nut body 1 outer surface applying pressure one end
There is multiple arcs groove 3, the thickness of the described region inner nut body 1 of arc groove 3 is less than the nut basis in remaining region
The thickness of body 1；Apply stressed small range region to be then located inside corresponding arc groove 3；It is being provided with arc groove 3 one end
Nut body 1 outer surface be provided with the conical surface 2, and in the region that is located of the conical surface 2, the thickness of nut body 1 end is minimum；Described
Arc groove 3 partially or fully be located at the conical surface 2 be located regional extent in.
Embodiment 2:
The stop nut of the present embodiment description, it includes nut body 1, and described nut body 1 is standard size；In spiral shell
The outer surface of maternal body 1 one end is provided with the conical surface 2, and the region at the conical surface 2 place, and the thickness of nut body 1 end is minimum；?
End six arc groove 3 corresponding to six planes of nut body 1 outer surface, at wherein three of six arc grooves 3
Internal a small range applies certain pressure to the inside of nut body 1 and forms the screw thread of this small range to nut body 1
Center is protruded.The deflection of the screw thread of above-mentioned a small range is the 10% of thread height.
Embodiment 3:
The stop nut of the present embodiment description, compared with Example 2, it is in six arc grooves 3 all by little for its difference
Scope applies certain pressure to the inside of nut body 1, and the screw thread forming this small range protrudes to the center of nut body 1；
The deflection of the screw thread of above-mentioned a small range is the 15% of thread height.
