Abstract
A kind of threaded anti-loosing structure, including the bolt being used cooperatively with check washer and for the connected part of fastening, wherein, the setting of bolt lower end is fluted, and the internal boss for being embedded in groove is internally provided in check washer, the exterior boss after inflection for being pressed on nut spanner working face is provided with outside check washer, nut is tightened on bolt along the screw thread guiding role of bolt, and check washer is pressed between nut and connected part；And the number of groove and internal boss is arranged in certain proportion；The present invention compares traditional locking thread method so that nut is thinner, and saves conventional spacers part, and mitigated using the assembly weight of this connection type, be compact-sized, repeatable dismounting, anti-loosing effect it is more preferable, do not influence in structure other into attachment and access be installed.
Description
Technical field
The present invention relates to loosing Prevention Technology field more particularly to a kind of threaded anti-loosing structures.
Background technique
Aircraft uses a large amount of threaded form in the structures such as body, undercarriage, and screw thread is anti-due to safety concerns
Pine is the technical issues of must solving.The locking thread form used in the structures such as body, undercarriage at present is rushed point type and is stopped
Dynamic pin, rushes that point type is locking to be easily damaged part, is not suitable for the structure for repeating to dismount；Although stop pin is locking to be damaged
Part can also be used for the structure for repeating to dismount, but this locking form can generate the deficiencies of assembly weight is big, back gauge requirement is big, and
Other install access at attachment in influence structure.
Summary of the invention
Technical problem solved by the invention is to provide a kind of threaded anti-loosing structure, to solve in above-mentioned background technique
Disadvantage.
Technical problem solved by the invention is realized using following technical scheme：
A kind of threaded anti-loosing structure, including the bolt being used cooperatively with check washer and for the connected part of fastening, wherein
The setting of bolt lower end is fluted, and is internally provided with the internal boss for being embedded in groove in check washer, outside check washer
Portion is provided with the exterior boss after inflection for being pressed on nut spanner working face, and nut is revolved along the screw thread guiding role of bolt
Tightly on bolt, check washer is pressed between nut and connected part；And the number of groove and internal boss is in certain
Ratio setting.
In the present invention, check washer is annular, rectangular, round.
In the present invention, the number Set scale 1 of groove and internal boss:1, to realize that bolt and check washer fastening connect
It connects.
In the present invention, multiple exterior boss are provided with outside ring structure.
In the present invention, the internal boss being arranged in exterior boss is integrally formed with exterior boss.
In the present invention, in use, first bolt is fully inserted into connected part, then by check washer from the spiral shell of bolt
Bolt is pierced at line end, while the internal boss of check washer being fastened in the groove of bolt, then nut is tightened on bolt,
It will be finally pressed on nut spanner working face after the exterior boss inflection of check washer, so that nut can not generate phase with bolt
To movement, to realize locking thread purpose.
Beneficial effect：The present invention compares traditional locking thread method, so that nut is thinner, and saves conventional spacers zero
Part, and mitigated using the assembly weight of this connection type, compact-sized, repeatable dismounting, anti-loosing effect it is more preferable, do not influence structure
Above other install access at attachment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of presently preferred embodiments of the present invention.
Fig. 2 is the bolt arrangement schematic diagram in presently preferred embodiments of the present invention.
Fig. 3 is the check washer structural schematic diagram in presently preferred embodiments of the present invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to a kind of threaded anti-loosing structure of FIG. 1 to FIG. 3, including bolt 1, nut 2, check washer 3, be connected part 4,
Groove 5, internal boss 6 and internal boss 7,1 lower end of bolt setting fluted 5, check washer 3 is ring structure, and in ring
Shape inside configuration is provided with the internal boss 6 for being embedded in groove 5, is provided with after inflection outside ring structure for being pressed on spiral shell
Exterior boss 7 on female 2 spanner working faces, nut 2 are tightened on bolt 1 along the screw thread guiding role of bolt 1, check washer 3
It is fastened on bolt 1, is pressed between nut 2 and connected part 4 by internal boss 6.
In the present embodiment, 1 lower end of bolt is provided with multiple grooves 5.
In the present embodiment, the internal boss 6 with 5 same number of groove is provided in ring structure, with realize bolt 1 with
Check washer 3 is fastenedly connected.
In the present embodiment, there are four exterior boss 7 for setting outside ring structure.
In the present embodiment, in use, first bolt 1 is fully inserted into connected part 4, then by check washer 3 from spiral shell
The end of thread of bolt 1 pierces into bolt 1, while the internal boss of check washer 36 being fastened in the groove 5 of bolt 1, then by nut 2
It is tightened on bolt 1, will be finally pressed on after 7 inflection of exterior boss of check washer 3 on 2 spanner working face of nut by locking
The effect of gasket 3, so that nut 2 and bolt 1 can not generate relative motion, to realize locking thread purpose.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
