Abstract
A kind of overhead transmission line anti-corona anti-loose connecting bolt component, overhead transmission line technical field.Including bolt, nut and closed pin, the bolt includes head and the screw rod being downwardly extending from the head bottom surface, the screw rod includes the light bar segment being downwardly extending from head, the thread segment extended downwardly from the light bar segment, and the nut is connected on the thread segment of bolt；Corresponding pin-and-hole of remaining silent is provided between the thread segment of the nuts and bolt, when the locking pin hole between nut is threaded to nuts and bolt overlaps, is locked by closed pin.After nut of the present utility model is screwed to certain position, locked between nut and bolt by closed pin, thoroughly solve bolt releases problem, ensures normal, the safe handling of equipment.
Description
Technical field
The utility model belongs to overhead transmission line technical field, is specifically related to a kind of overhead transmission line with anti-corona anti-loose
Connecting bolt component.
Background technology
Now, need to use bolt to be attached and anti-loose in many of industrial circle place, it is desirable to be do not release,
It is durable in use, but in general bolt, in the situation by judder, bolt is likely to release, and bolt, which releases, is possible to shadow
Ring service life, machine security and the personal safety of equipment.In addition, in field of overhead power transmission lines, hex-head nut usually can
Bring the problem of producing corona.
Utility model content
The purpose of this utility model is to provide a kind of anti-corona anti-loose connecting bolt component of overhead transmission line, can thoroughly solve
Bolt releases problem, and with preferable anticorona performance.
Realizing the technical scheme of above-mentioned purpose is：A kind of overhead transmission line anti-corona anti-loose connecting bolt component, its feature
It is：Including bolt, nut and closed pin, the bolt includes head and the spiral shell being downwardly extending from the head bottom surface
Bar, the screw rod include the light bar segment being downwardly extending from head, the thread segment extended downwardly from the light bar segment, the spiral shell
Mother is connected on the thread segment of bolt；Corresponding pin-and-hole of remaining silent is provided between the thread segment of the nuts and bolt, works as nut
When the locking pin hole being threaded between nuts and bolt overlaps, locked by closed pin.
Further, the nut is in cylinder, and the outer rim at both ends sets rounding, effectively increases fastening bolt
The anticorona performance of component.
Further, the bolt head is in semicircle capitiform, and stub end is provided with trimming and is formed square, effectively improves
The anticorona performance of fastening bolt component.
After nut of the present utility model is screwed to certain position, locked between nut and bolt by closed pin, thoroughly solution
Certainly normal, the safe handling that release problem, ensure equipment of bolt.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes bolt 1 and nut 2, nut 2 is in cylinder, and the outer rim at both ends is set
Rounding
Bolt 1 includes head 11 and the screw rod 12 being downwardly extending from the bottom surface of head 11, and head 11 is in cup head
Shape, and stub end be provided with trimming formed it is square, screw rod 12 include be downwardly extending from head 11 light bar segment 121, from
The thread segment 122 that the light bar segment 121 extends downwardly, nut 2 are connected on the thread segment 122 of bolt 1；Nut 2 and bolt 1
Locking pin hole 3 corresponding to being provided between thread segment 122, when the locking pin hole 3 that nut 2 is threaded between nut 2 and bolt 1 overlaps
When, locked by closed pin 4.
