Abstract

The invention discloses a kind of Anti-loosening nuts, belong to mechanical fastening technique field.It solves the anti-loosening defect with shockproof function difference existing for conventional nut in the prior art.Its agent structure includes the first nut and the second nut, one side end face of first nut is equipped with boss, the boss, which is equipped with, tightens grooving, and second nut is equipped with the groove for the installation that cooperates with the boss on the first nut, first nut and the cooperation installation of the second nut.Present invention is mainly used for steel tower, freeway guardrail, trains etc..

Description

Anti-loosening nut
Technical field:
The invention belongs to mechanical fastening technique fields, specifically, more particularly to a kind of Anti-loosening nut.
Background technology:
Bolt and nut component has extensive purposes daily, is mainly used for the installation and fastening of various components, existing Nut is made of tapped nut, is installed and is easy with dismounting, but is anti-loosening poor with shockproof function.
Invention content:
In order to solve the anti-loosening disadvantage with shockproof function difference existing for conventional nut in the prior art, the present invention provides A kind of Anti-loosening nut being different from the prior art, manufacturing process is simple, cheap and simple to operate, anti-high intensity Fatigue vibrations, can be anti-loosening.
To achieve the goals above, realization that the present invention adopts the following technical solutions:
A kind of Anti-loosening nut, including the first nut and the second nut, a side end face of first nut is equipped with convex Platform, the boss, which is equipped with, tightens grooving, and second nut is equipped with and the boss mutual cooperation installation on the first nut Groove, first nut and the cooperation installation of the second nut.
Further, the boss on first nut is eccentric boss.
Further, the grooving that tightens is evenly distributed with two to seven.
Further, the height of the boss is h, and the value range of h is more than or equal to the internal thread diameter of the first nut 0.5 times, it is less than or equal to 3 times of the internal thread diameter of the first nut.
Further, the angle between the inclined surface and plane of the boss isValue range be more than or equal to 35 °, it is less than or equal to 75 °.
Further, the boss is structure as a whole with the first nut.
Compared with prior art, the beneficial effects of the invention are as follows:
1, manufacturing process is simple, cheap and simple to operate;
2, anti-high intensity fatigue vibrations, can avoid loosening;
3, material can voluntarily be selected according to purposes, and can be reused, and avoid disposably wasting.
Description of the drawings:
Fig. 1 is the front view of the first nut in the present invention;
Fig. 2 is the stereogram of the first nut in the present invention;
Fig. 3 is the front view of the second nut in the present invention;
Fig. 4 is the structural schematic diagram that the present invention installs and uses.
In figure:1, the first nut;2, boss;3, grooving is tightened;4, the second nut;5, groove;6, gap;7, bolt.
Specific implementation mode:
Below by specific embodiment and in conjunction with attached drawing, the invention will be further described.
Embodiment 1:
As shown in Figs. 1-3, a kind of Anti-loosening nut, including the first nut 1 and the second nut 4, the one of first nut 1 Side end face is equipped with boss 2, and the boss 2 is equipped with and tightens grooving 3, second nut 4 be equipped with and the first nut 1 on The groove 5 of the mutual cooperation installation of boss 2, the cooperation installation of first nut, 1 and second nut 4.
Embodiment 2:
A kind of Anti-loosening nut, the boss 2 on first nut 1 are eccentric boss;The grooving 3 that tightens is uniformly distributed There are two to seven;The height of the boss 2 is h, and the value range of h is more than or equal to the 0.5 of the internal thread diameter of the first nut 1 Times, be less than or equal to 3 times of internal thread diameter of the first nut 1, if h it is too big or it is too small all can not be to the first nut 1 and the second spiral shell Mother 4 plays locking and anticreep purpose;Angle between the inclined surface and plane of the boss 2 isValue range it is big In equal to 35 °, it is less than or equal to 75 °,It is too big or too small can not all play locking and anticreep to the first nut 1 and the second nut 4 Purpose;The boss 2 is structure as a whole with the first nut 1.
Tighten grooving 3 quantity cannot too much can not be very little, quantity is very little, is not achieved and tightens and prevent the second nut 4 The effect of loosening, quantity are easily destroyed the intensity of boss 2 too much.
The operation principle that the present invention installs and uses is:
As shown in figure 4, bolt 7 is sleeved on installed object, then the first nut 1 is screwed on bolt 7, then by second Nut 4 screws on bolt 7, and the boss 2 on the first nut 1 screws in the groove 5 on the second nut 4.It is convex on first nut 1 Eccentric processing is used when platform 2 manufactures, the second nut 4 is then normal central circular processing, when the first nut 1 and the second nut 4 It is threaded together, just as being inserted into chock in nut, to realize anti-loosening effect.
It, can there are gaps at one between boss 2 and groove 5 when tightening since the boss 2 on the first nut 1 is eccentric boss 6, but under the action of tightening grooving 3, internal thread on the first nut 1 can be to contract and the screw rod on " holding " bolt 7, just The screw thread of soft phase Ji (i.e. harder material can be used in the first nut 1 and the second nut 4) increases frictional force, and it is tired to reach anti-high intensity Labor shakes and tight effect;Even if therefore the first nut 1 on bolt 7 and the second nut 4 are tired in generation high intensity In the case that labor shakes, it will not loosen.
