Abstract
A self-locking anti-loosing and theft nut comprises a nut body (1) and is characterized in that the nut also comprises a socket (2), a locking tongue (3), a spring (4), spring mounting holes (5) (6). The technical proposal of the nut is simple and skillful. The processing and manufacturing of the nut is simple and practical. The shape of the nut is identical with the national standard. The traditional use habit is not changed and the anti-loosing and theft is assured reliable. The nut is particularly suitable for the needs of outdoor electric steel towers, freeway flanges, railroads, bridge facilities, other large scale steel structures and the like and is the ideal self-locking anti-loosing and theft nut.
Description
Technical field
The present invention relates to the fastener of mechanical field, specifically a kind of self-locking anti-theft locknut.
Background technique
The fastening piece of people's extensive use at present, many situations are the nonvolatil dismountings that do not need, this type of fastening piece that can really play effect of supplying on the market does not also occur, prior art from the patent documentation record, do not find better solution yet, therefore, because of causing the serious accident of getting loose of nut or theft initiation artificially, the wind-force vibration often takes place.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned present situation, provides a kind of simple and reliable for structure, and methodological science is reasonable, manufactures easily and goes, and uses economy self-locking anti-theft locknut easily.
Technical solution of the present invention:
1. in shape, the present invention is fully according to existing NBS, and the benefit of bringing like this is self-evident.
2. on the supporting end face of nut body, be provided with one or more than one groove.
3. a kind of locking tongue that can swing is installed in groove, and an end of locking tongue is provided with together or above together sharp tooth.
The arc column body portion of 4. locking tongue is that intercalation is installed in the arc column cavity in the groove, and both joint clearances are movingly, and the waist on the mating face is provided with an annular aperture.
5. an end of spring inserts and to be installed in the annular aperture, and the other end elastic force presses in the slotted eye on the locking tongue.
Beneficial effect of the present invention:
Technological scheme of the present invention is simply ingenious, the manufacturing economy and facility, anti-loose anti-theft is relieved reliable, identical on the profile with NBS, do not change traditional use habit, be particularly suitable for open-air electric power tower, expressway rib, the needs of aspects such as railway and bridge facility and other large-scale steel structure.
Description of drawings
Fig. 1 is a plane structure schematic representation of the present invention.
Fig. 2 is that overall structure axle of the present invention is surveyed schematic representation.
Embodiment
Below in conjunction with accompanying drawing the present invention and concrete enforcement are described further:
Referring to accompanying drawing, at the supporting end face of nut body (1), just be provided with one or more than one groove (2) on that face of workpiece pressing, if more than one groove, should be distributed on the periphery of nut bore, the degree of depth of groove (2) should that is to say that the degree of depth that the height of nut inner thread complete segment adds upper groove equals nut height of the present invention less than the height of nut body (1), the height of internal thread complete segment is selected for use by NBS, also can increase and decrease by actual demand.
Locking tongue (3) is installed in the groove (2), one end arc column body portion of locking tongue (3) is mounted in the interior arc column cavity of groove (2), the other end of locking tongue (3) is provided with together or the above together heat treated sharp tooth of process, locking tongue (3) can rely on the arc column cavity to resemble in groove (2) and swing the rocking arm, the height of locking tongue (3) can equal the degree of depth of groove (2), also can be slightly less than the degree of depth of groove (2), the length of locking tongue (3), thickness, parameter such as tooth depth and hardness is the size according to the geometrical shape of nut body (1), the work stressing conditions, Environmental Conditions, customer requirements or the like combined factors is determined, and can be formulated standard.
Waist on the mating face of the arc column part of locking tongue (3) and groove (2) is provided with together total annular aperture (5), and an end intercalation of spring (4) is in annular aperture (5), and the other end elastic force of spring (4) presses in the slotted eye (6) on locking tongue (3).The spring action here is two aspects, is to locking tongue (3) with elastic force on the one hand, and behind nut precession bolt, the tooth on the locking tongue (3) in the nut leans against on the bolt under the elastic force effect all the time; Be the outer race of restriction locking tongue (3) on the other hand.
Optimum configuration of the present invention is the hexagon nut with flange pattern.
Self-lock mechanism of the present invention is apparent, and the internal thread on the nut body (1) is dextrorotation or contrary revolving, and its principle is identical, does not just give unnecessary details here.
Claims (4)
1, a kind of self-locking anti-theft locknut comprises nut body (1), it is characterized in that:
A, on the supporting end face of nut body (1), be provided with one or more than one groove (2);
B, in groove (2), be equipped with locking tongue (3);
C, locking tongue (3) are provided with together or the above together heat treated sharp tooth of process;
One end intercalation of d, spring (4) is installed in the annular aperture (5), and the other end elastic force presses in the slotted eye (6) in locking tongue (3).
2, self-locking anti-theft locknut according to claim 1, it is characterized in that locking tongue (3) plane outwardly can be domatic near the position of increment.
3, self-locking anti-theft locknut according to claim 1, the tooth that it is characterized in that locking on the tongue (3) can be parallel with bus in the nut at width direction, also can with bus in the nut at an angle.
4, self-locking anti-theft locknut according to claim 1 is characterized in that the profile of tooth of tooth on width direction on the described locking tongue (3) can be flat shape, also can be identical with screw thread form on the nut body (1).
