Background technology
Nut anti-looseness is a long-standing technology, at present existing many loosing Prevention Technologies.But existing loosing Prevention Technology
It can only under normal circumstances be applicable, under some severe operating modes, be not met by the requirement used, nut loosening causes to dislike
The phenomenon of sexual behavior event still happens occasionally, so the improvement of nut anti-looseness technology is imperative.
In addition, nut is typically used cooperatively with bolt, use occasion extensively, out of doors with the occasion of deep-etching in use,
Easily got rusty between two nuts, remove extremely difficult after getting rusty, therefore the antirust problem of nut must be also resolved.
Utility model content
For defect present in prior art, the utility model provides a kind of antidetonation combination nut, is shaking larger field
Under conjunction, nut loosening can be prevented, it is ensured that the security of equipment；In the presence of a harsh environment, it is to avoid get rusty, it is easy to repair demolition.
To achieve the above objectives, the technical solution adopted in the utility model is：A kind of antidetonation combination nut is provided, including with
The recessed nut and knurled nut used is closed, the recessed nut is that the groove rounded is set in one end of plain nut, described convex
Nut is that the projection rounded is set in one end of plain nut, and groove is adapted with projection, medial surface and the projection of groove
Lateral surface be taper surface, the center line of groove medial surface is overlapped with the center line of its internal thread, the center of raised lateral surface
The center line of line and its internal thread has certain offset.
Further, a kind of antidetonation combination nut as described above, the recessed nut, which is provided with, to be used to lubricate taper surface
Lubrication system.
Further, a kind of antidetonation combination nut as described above, the lubrication system includes tank filler sleeve and oil groove.
Further, a kind of antidetonation combination nut as described above, the tank filler sleeve is axially obliquely installed along recessed nut.
Further, a kind of antidetonation combination nut as described above, the oil groove is set around the taper surface of recessed nut.
Advantageous effects of the present utility model are：
(1) the utility model is coordinated using knurled nut with recessed nut, medial surface and the knurled nut projection of recessed nut groove
Lateral surface uses taper surface structure, and the taper surface center line of recessed nut is overlapped with its nut inner thread center line, knurled nut
There is certain offset between taper surface center line and the center line of its nut inner thread；Thus, screw bolt and nut screw thread it
Between form tight fit, completely eliminate the gap between screw thread, in the case of any vibrations, it is this cooperation all without quilt
Destruction, so as to reach the effect of shock-proof check；
(2) the utility model on recessed nut by being provided with tank filler sleeve and oil groove, so as to prevent nut in the presence of a harsh environment
Get rusty, it is easy to disassemble.

Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is described in further detail.
As shown in figure 1, being a kind of antidetonation combination nut that the utility model is provided, including recessed nut 1 and knurled nut 2 should
Recessed nut 1 and knurled nut 2 pairing is used.
As shown in Figure 2-5, it is the structural representation of the utility model antidetonation combination nut concave nut 1 and knurled nut 2.It is recessed
Nut 1 is that the groove rounded is set in one end of plain nut, and knurled nut 2 is to be set in one end of plain nut around one
The projection in week, the groove of recessed nut 1 is adapted with the projection of knurled nut 2, medial surface and the knurled nut projection of the recessed groove of nut 1
Lateral surface is taper surface, and the center line of the groove medial surface of recessed nut 1 is overlapped with the center line of its internal thread, and knurled nut is raised
The center line of lateral surface has certain offset D, offset D size and the pitch of screw thread with the center line of its internal thread
Relevant, the size of pitch is determined according to actual needs.
Thus, the utility model uses the medial surface of said structure, i.e. groove and raised lateral surface to use taper surface,
The center line of groove taper surface is overlapped with its nut inner thread center line, center line and its nut inner thread of raised taper surface
There is certain offset between center line.As shown in figure 1, its with bolt 5 with the use of when, in bolt 5 and combination nut
Close cooperation is formd between screw thread, the gap between screw thread is completely eliminated, it is this to coordinate in the case of any vibrations
All without destroyed, so as to reach the effect of shock-proof check.
Further, since many nuts are installed on open air, easily get rusty, in order to prevent the taper surface coordinated between convex-concave nut
Get rusty, recessed nut 1 is provided with the lubrication system for being used for lubricating taper surface, the lubrication system includes tank filler sleeve 3 and oil groove 4, refuels
Hole 3 is set along recessed nut 1 is axially inclined, and oil groove 4 is set around the taper surface of recessed nut.So, when mounted, oil groove 4 is smeared
Upper lubricating oil, it is ensured that taper surface will not touch water, lubrication taper surface can be played during maintenance repair by the oiling of tank filler sleeve 3
Effect, so as to ensure that taper surface will not can not be dismantled because getting rusty.
During installation, the erection sequence of convex-concave nut is not required, first tightened convex (or recessed) nut on bolt, then will
Recessed (or convex) nut is tightened on bolt, until the circular conical surface of concavo-convex nut reaches close-fitting state.At this moment can be two
The screwing force and screw-down torque perpendicular to taper surface are formed between the taper surface of individual convex-concave nut, perpendicular to the screwing force of taper surface
The fastening force perpendicular to the center line of bolt 5 and the fastening force parallel to bolt centerline (being pretightning force) are can be analyzed to, vertically
The direction of recessed nut 1 towards bolt-center is pulled in the fastening force of bolt centerline, knurled nut 2 is then pushed into the opposite direction,
So as to which the gap between the screw thread of convex-concave nut and the screw thread of bolt is completely eliminated, realizes and be fitted close.Thus, it is tight at these three
Gu in the presence of power, it is ensured that the stability that bolt and nut coordinates.
Plain nut in text refers to have female polygonal nut.
Antidetonation combination nut of the present utility model is not limited to above-mentioned embodiment, and those skilled in the art are according to this
The technical scheme of utility model draws other embodiments, also belongs to technological innovation scope of the present utility model.
