Description
Technical field
The utility model relates to nut technical fields, and in particular to a kind of nut structure of never becoming loose.
Background technique
Nut is the part being threaded together with bolt or screw rod for playing the role of fastening.Nut mostly makes in machinery field
With being used to fasten mechanical part.
Nut in the prior art only opens up a tooth in its inner sidewall.However, when nut environment biggish for amplitude,
Such as in environment such as high-speed rail, aircraft, automobile, trains, vibration motion will lead to bolt and occur along the inclined-plane of the silk tooth of nut
Sliding, when the sliding force for vibrating inclined-plane is greater than the frictional force of silk tooth, bolt will loosen, in this way can to vehicle safety or
Machinery, which uses of seat belts, has carried out biggish hidden danger.
Utility model content
For the prior art there are above-mentioned technical problem, the utility model provides a kind of nut structure, the nut structure with
It is bolted never becoming loose, has the advantages that structure is simple, easy to use.
To achieve the above object, the utility model the following technical schemes are provided:
A kind of nut structure of never becoming loose is provided, including the first nut screwed in for bolt, outside first nut
Sidewall sheath is equipped with the second nut, and the inner sidewall of first nut offers internal thread tooth, and the lateral wall of first nut is opened
Equipped with outer silk tooth, the silk tooth of both the internal thread tooth of first nut and its outer silk tooth is contrary, second nut it is interior
Side wall offers internal thread tooth, the silk tooth direction in the silk tooth direction of the internal thread tooth of second nut and the outer silk tooth of a nut
Identical, second nut is by the pairing of the outer silk tooth of its internal thread tooth and first nut to be set in first nut
Lateral wall.
Wherein, the periphery of the end of first nut is equipped with all edges, and the one end of second nut can be with the week
Along abutting.
Wherein, the one end of second nut and the week are equipped with steel spring pad, the spring side of the steel spring pad between
To identical as the silk tooth direction of first nut, an end of second nut passes through the steel spring pad and all edges
It abuts.
Wherein, the internal thread tooth of first nut is orthodontic wires tooth, and the outer silk tooth of first nut is anti-Ya Siya.
Wherein, the end for second spiral shell being pierced by for bolt is longer than the end for first spiral shell being pierced by for bolt.
Wherein, the end of first spiral shell of the end for second spiral shell being pierced by for bolt than being pierced by for bolt is 1- long
5mm。
Wherein, the internal thread tooth of first nut, first nut outer silk tooth be equably opened in respectively its inside
The internal thread tooth of wall and lateral wall, second nut is equably opened in its inner sidewall.
Working principle: the internal thread tooth of the first nut is contrary with the silk tooth of its outer silk tooth, and bolt is interior with the first nut
Silk tooth pairing, the second nut is by the internal thread tooth pairing of the internal thread tooth and the first nut of the second nut to cover in the first nut
On, when mechanical oscillation, the sliding force that bolt generates rotates the first nut, meanwhile, the vibration of the first nut makes the second nut
Generate with the rotation of the first nut opposite direction, therefore, the direction of rotation of the direction of rotation of the first nut and the second nut on the contrary,
The direction of rotation opposite effect power mutually restricts, so that nut never becoming loose.
The utility model has the beneficial effects that
The direction of rotation of the direction of rotation of bolt in first nut and the second nut is on the contrary, generated sliding force phase
Instead, it so that the first nut is mutually restricted with the second nut, so that the nut structure and being bolted never becoming loose, mentions significantly
High nut and bolted stability, ensure that the safety in utilization of Machinery Ministry.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the nut structure of never becoming loose of the utility model.
Appended drawing reference:
First nut --- the internal thread tooth of the 1, first nut --- the outer silk tooth of the 11, first nut --- 12；Second spiral shell
Female --- internal thread tooth of the 2, second nut --- 21；Bolt --- 3；All edges --- 4；Steel spring pad --- 5.
Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
Embodiment 1.
The nut structure of a kind of never becoming loose as shown in Figure 1, including the first nut 1 that bolt 3 screws in, the first nut 11
Lateral wall be arranged with the second nut 2, the silk tooth side of the outer silk tooth 12 in the direction and the first nut of the internal thread tooth 11 of the first nut
To on the contrary, the silk tooth direction of the internal thread tooth 21 of the second nut is identical as the silk tooth direction of outer silk tooth 12 of a nut, second
The internal thread tooth 21 of nut and the outer silk tooth 12 of the first nut match the lateral wall for being set in first nut 1, specifically,
The internal thread tooth 11 of first nut is orthodontic wires tooth, and the outer silk tooth 12 of the first nut is anti-Ya Siya.
In the present embodiment, the periphery of the end of the first nut 1 is equipped with week can be with all edges along an end of 4, second nuts 2
4 abut, to limit the screw-in position of the second nut 2.
In the present embodiment, the end of the second nut 2 is equipped with steel spring pad 5, the spring direction of steel spring pad 5 along 4 places of abutting with week
Identical as the silk tooth direction of the first nut 1, the end of the second nut 2 is abutted with week along 4 by steel spring pad 5.Steel spring pad 5 is due to bullet
The effect of power generates certain frictional force, connects the first nut 1 and the second nut 2 and is not easy to loosen.When unscrewing nut, pressure is twisted
To the second nut 2 of steel spring pad 5, while the first nut 1 is unscrewed, so that the first nut 1 and the second nut 2 are unscrewed completely.
In the present embodiment, the end for the first nut 1 being pierced by for bolt 3 is longer than for the end for the second nut 2 that bolt 3 is pierced by
Portion, so that the second nut generates frictional force；Specifically, the end of the second nut 2 being pierced by for bolt 3 for bolt 3 than being pierced by
The long 1-5mm in end of first nut 1.
In the present embodiment, the internal thread tooth 11 of the first nut, the outer silk tooth 12 of the first nut equably open up in the inner respectively
The internal thread tooth 21 of side wall and lateral wall, the second nut is equably opened in its inner sidewall, ensure that the firmness of nut structure.
The application method of this nut structure is: first by 5 sets of steel spring pad on the first nut 1, then the second nut 2 being inserted in
On the lateral wall of one nut 1 and steel spring pad 5 is compressed, then the first nut 1 and the second nut 2 mutually tightened for screwing in bolt
It 3 and tightens.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
