Abstract
The present invention discloses a kind of bolt, nut assembly with loosening prompt facility, for prompting work of transformer substation personnel's bolt looseness situation.The present invention includes screw bolt and nut interconnected, and the center of circle is provided with a circle protruding block of its bottom dead center position on bolt bottom end, and the bottom end of the nut is provided with a circle protruding block by the center of circle of bolt bottom dead center position.Whether the present invention concordantly judges the elastic situation of bolt, feature cheap with improvement cost, highly-safe by the protruding block of observation screw bolt and nut bottom surface.
Description
Technical field
The present invention relates to electric power maintenance fields, more particularly, to a kind of with the bolt, the nut group that loosen prompt facility
Part.
Background technique
No matter big and small bolt on power equipment which kind of material and structure is used, due to being chronically at electromagnetic field ring
It in border, is influenced by electromagnetic stress, induced electricity etc., often there is oscillation phenomenon, caused bolt to be inevitably easy to loosen, influence
Equipment operation, brings certain risk hidden danger.
Currently, indoor equipment, common practices is to tighten junction white board marker of rear bolt and nut etc. in bolt to apply
Material does a mark line, if being displaced between bolts and nuts, mark line displacement keeps nut loosening immediately intuitive and convenient
Ground is found.It is common to scribble label and save for a long time due to uncontrollable factors such as exposing to the weather but in outdoor, it marks
Often failure, only nut could find that risk is still uncontrollable after obviously loosening.
Summary of the invention
The present invention is to overcome the above-mentioned defect that can not be provided bolt looseness for a long time in the prior art and remind, and provides a kind of tool
There are bolt, the nut assembly for loosening prompt facility.
In order to solve the above technical problems, technical scheme is as follows:A kind of bolt, spiral shell with loosening prompt facility
Female component includes screw bolt and nut interconnected, and the center of circle is provided with a circle of its bottom dead center position on the bolt bottom end
The bottom end of protruding block, the nut is provided with a circle protruding block by the center of circle of bolt bottom dead center position.
After nut is tightened, the tools such as the protruding block being aligned on screw bolt and nut screwdriver are knocked out respectively, make bolt
With the notch alignment for lacking protruding block on nut, once nut loosening, notch will be no longer aligned, and operation maintenance personnel will at this time
Observe the loosening of bolt with intuitively having very much foundation.
Preferably, the protruding block is uniformly distributed on the bottom surface of one end of screw bolt and nut connection.
Preferably, the protruding block is directed toward center of circle direction.
Compared with prior art, the beneficial effect of technical solution of the present invention is:By increasing on screw bolt and nut bottom surface
Protrusion knocks out the protruding block being aligned on screw bolt and nut after nut is tightened, and staff can lack by observation convex
Bittiness gap position state intuitively judges the tightness of nut, and then improves the safety of bolt and nut.
Detailed description of the invention
Fig. 1 is structure chart when bolt and nut of the present invention is tightened.
Fig. 2 is the structure chart of bolt of the present invention.
Fig. 3 is the structure chart of nut of the present invention.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent;
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the ruler of actual product
It is very little;
To those skilled in the art, the omitting of some known structures and their instructions in the attached drawings are understandable.
The following further describes the technical solution of the present invention with reference to the accompanying drawings and examples.
Embodiment 1
Fig. 2 is the structure chart of invention bolt, and the center of circle is provided with a circle protruding block of its bottom dead center position on 1 bottom end of bolt
2。
Fig. 3 is the structure chart of nut of the present invention, and the bottom end of the nut 3 is provided with using bolt bottom dead center position as the center of circle
One circle protruding block 4.
As shown in Figure 1, in the specific implementation process, after nut 3 is tightened, the protruding block that will be aligned on bolt 1 and nut 3
It is knocked out respectively with tools such as screwdrivers, makes the notch alignment for lacking protruding block on bolt 1 and nut 3, once nut loosening,
Notch will be no longer aligned, and operation maintenance personnel observes the loosening of bolt in which will intuitively have very much foundation at this time.
The same or similar label correspond to the same or similar components;
The terms describing the positional relationship in the drawings are only for illustration, should not be understood as the limitation to this patent;
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to this hair
The restriction of bright embodiment.For those of ordinary skill in the art, it can also do on the basis of the above description
Other various forms of variations or variation out.There is no necessity and possibility to exhaust all the enbodiments.It is all in the present invention
Spirit and principle within made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the claims in the present invention
Within the scope of shield.
