Description
Technical field
The present invention relates to nut technical fields, and in particular to a kind of positive and negative silk tooth nut structure.
Background technology
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 madial wall.However, when the nut environment larger for amplitude,
Such as in environment such as high ferro, aircraft, automobile, trains, vibration motion can cause bolt to occur along the inclined-plane of the silk tooth of nut
Sliding, when vibrate inclined-plane sliding force be more than silk tooth frictional force when, bolt will loosen, in this way can give vehicle safety or
Machinery is safe to use to have brought larger hidden danger.
Invention content
For the prior art there are above-mentioned technical problem, the present invention provides a kind of positive and negative silk tooth nut structure, the nut knot
Structure and it is bolted never becoming loose, had the advantages that simple in structure, easy to use.
To achieve the above object, the present invention provides following technical scheme：
A kind of positive and negative silk tooth nut structure is provided, includes the first nut screwed in for bolt, the lateral wall set of first nut
Equipped with the second nut, the madial wall of first nut offers internal thread tooth, and the lateral wall of first nut offers outside
The silk tooth direction of both silk tooth, the internal thread tooth of first nut and its outer silk tooth is on the contrary, the madial wall of second nut is opened
Equipped with internal thread tooth, the silk tooth direction of the internal thread tooth of second nut is identical as the outer silk tooth direction of silk tooth of a nut,
Second nut matches to be set in the outer of first nut by the outer silk tooth of its internal thread tooth and first nut
Side 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 the 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 long 1-
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 madial wall.
Operation principle：The silk tooth direction of the internal thread tooth of first nut and its outer silk tooth on the contrary, bolt and the first nut it is interior
Silk tooth pairing, the second nut are matched by the internal thread tooth of the second nut and the internal thread tooth of the first nut to be sleeved on the first nut
On, when mechanical oscillation, the sliding force that bolt generates makes the first nut rotate, 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.
Beneficial effects of the present invention：
The direction of rotation of the direction of rotation of bolt in first nut and the second nut on the contrary, generated sliding force on the contrary, making
The first nut mutually restricted with the second nut so that the nut structure be bolted never becoming loose, substantially increase
Nut and bolted stability, ensure that the safety in utilization of Machinery Ministry.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of positive and negative silk tooth nut structure of the present invention.
Reference numeral：
First nut --- the internal thread tooth of the 1, first nut --- the outer silk tooth of the 11, first nut --- 12；Second nut ---
2, the internal thread tooth of the second nut --- 21；Bolt --- 3；All edges --- 4；Steel spring pad --- 5.
Specific implementation mode
Below in conjunction with specific embodiment and attached drawing, the present invention is described in detail.
Embodiment 1.
A kind of positive and negative silk tooth nut structure as shown in Figure 1 includes the first nut 1 of the screw-in of bolt 3, the first nut 11
Lateral wall is arranged with the second nut 2, the silk tooth direction in the direction of the internal thread tooth 11 of the first nut and the outer silk tooth 12 of the first nut
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, the second spiral shell
The outer silk tooth 12 of female internal thread tooth 21 and the first nut matches to be set in the lateral wall of first nut 1, specifically, the
The internal thread tooth 11 of one 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 with week along 4 places of abutting
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, so that the first nut 1 and the second nut 2 is connected and is not easy to loosen.When unscrewing nut, pressure is twisted
To the second nut 2 of steel spring pad 5, while unscrewing the first nut 1 so that the first nut 1 and the second nut 2 are unscrewed completely.
In the present embodiment, the end for the second nut 2 being pierced by for bolt 3 is longer than the end for the first nut 1 being pierced by for bolt 3
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 madial wall, ensure that the firmness of nut structure.
The application method of this nut structure is：First steel spring pad 5 is sleeved on the first nut 1, then the second nut 2 is 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 the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
