Abstract
The utility model discloses a kind of stop nut, this stop nut includes nut body, the nut body side is provided with pit by impact, and nut body thread segment corresponding with the pit effect of being hit forms interference fit with the bolt thread for being screwed into nut with deformed area, the deformed area.This stop nut simple structure, it is easy to be obtained, and be prevented effectively from the loosening of nut and bolt, it is ensured that nut and the pretightning force of bolt, has prevented nut potential safety hazard in use.
Description
Technical field
This utility model is related to a kind of stop nut.
Background technology
Nut is threaded fastener, and its considerable advantage is to dismantle and reuse, and usual nut is twisted in the outer of bolt
Screw thread realizes the fastening of workpiece with pretightning force, in practical application with workpiece vibration or stress often there is nut and bolt pine
Dynamic phenomenon, causes pretightning force to weaken or disappear so that the workpiece for being fastened loosens or comes off.According to statistics due directly to screw thread is loose
Caused by dynamic, security incident happens occasionally, wherein it is no lack of some catastrophic failures, therefore conventional nut is present necessarily in use
Potential safety hazard.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of stop nut, this stop nut simple structure, easily
In being obtained, and the loosening of nut and bolt is prevented effectively from, it is ensured that the pretightning force of nut and bolt, prevented nut in use
Potential safety hazard.
To solve above-mentioned technical problem, this utility model stop nut includes nut body, and the nut body side leads to
Overbump is provided with pit, and nut body thread segment corresponding with the pit effect of being hit is with deformed area, the deformed area
Interference fit is formed with the bolt thread for being screwed into nut.
Further, the pit is circular arc concave surface, taper concave surface or round dot concave surface.
Include nut body as this utility model stop nut employs above-mentioned technical proposal, i.e. this stop nut, institute
State nut body side and pit is provided with by impact, nut body thread segment corresponding with the pit effect of being hit is with change
Shape area, the deformed area form interference fit with the bolt thread for being screwed into nut.This stop nut simple structure, it is easy to be obtained,
And it is prevented effectively from the loosening of nut and bolt, it is ensured that and nut and the pretightning force of bolt, prevent nut safety in use
Hidden danger.
Description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is this utility model stop nut schematic diagram；
Side views of the Fig. 2 for Fig. 1；
Fig. 3 is the schematic diagram for connecting workpiece using this stop nut.
Specific embodiment
As depicted in figs. 1 and 2, this utility model stop nut includes nut body 1,1 side of the nut body to embodiment
Face is provided with pit 2 by impact, with the effect of being hit of 2 corresponding nut body of the pit, 1 thread segment with deformed area 3, institute
State deformed area 3 interference fit is formed with the bolt thread for being screwed into nut.
Preferably, the pit 2 is circular arc concave surface, taper concave surface or round dot concave surface.
The characteristics of this stop nut is, by the drift that presses, to apply vertical depressing force, while nut side forms pit,
Female thread local deformation is made, after deformation, nut forms interference fit with the bolt of assembling, and bolt is not being applied to lock power
Words, bolt is without in words precession nut；After certain precessing force is applied, bolt can be screwed into nut, in the same manner, not apply to release power
Words, bolt can not be back-outed nut, play locking effect.
The practical application of this stop nut is as shown in figure 3, connect the first workpiece 5 and second workpiece 6 using bolt 4, this is anti-
Loose nut body 1 is screwed into bolt 4, and when 2 position of pit of this stop nut is screwed onto, 4 screw thread of bolt was formed with 1 screw thread of nut
It is full of cooperation, so as to reach locking purpose.In punching course, by the size, the controllable nut thread of depth that control pit
Deflection, with the interference fit degree between adjustment bolt screw thread and nut thread.
Following table is the performance parameter comparison sheet that this stop nut is connected with conventional nut：
| Project | Screw thread specification | Lock power (N.M max) | First time withdraw force (N.M min) | Second withdraw force (N.M min) | 5th withdraw force (N.M min) |
| This nut | M3×0.5 | 0.6 | 0.14 | 0.1 | 0.06 |
| Conventional nut | M3×0.5 | 0.6 | 0.45 | 0.43 | 0.43 |
| This nut | M4×0.7 | 1.2 | 0.26 | 0.21 | 0.16 |
| Conventional nut | M4×0.7 | 1.2 | 1 | 0.96 | 0.96 |
| This nut | M5×0.8 | 2.3 | 0.36 | 0.29 | 0.23 |
| Conventional nut | M5×0.8 | 2.3 | 2.15 | 2.1 | 2.1 |
| This nut | M6×1.0 | 3 | 0.45 | 0.39 | 0.3 |
| Conventional nut | M6×1.0 | 3 | 2.85 | 2.8 | 2.8 |
| This nut | M8×1.25 | 10 | 0.9 | 0.78 | 0.58 |
| Conventional nut | M8×1.25 | 10 | 9.2 | 9.11 | 9.11 |
| This nut | M10×1.5 | 14 | 1.8 | 1.65 | 1.1 |
| Conventional nut | M10×1.5 | 14 | 13.1 | 12.96 | 12.96 |
As seen from the above table, this stop nut and conventional nut to lock power identical, and this stop nut of withdraw force is than tradition
Nut is much smaller, shows that the anti-loosening property of nut is good, and this stop nut is particularly well-suited to the neck such as aviation, automobile engine
Domain, it is effective antidetonation, locking, and Jing after many times are exited, withdraw force is almost unchanged.
