Plane the 3rd rotation prevention portion of formation；Nut rotation stop is put outside the second rotation stop hole for being provided with and coordinating with the peripheral shape of nut, nut
Side face the 4th rotation prevention portion of formation, medial surface the 5th rotation prevention portion of formation in the second rotation stop hole, the periphery covered in nut rotation stop is convex in the same direction
Go out multiple equally distributed card articles, the hook that the end face of card article is provided with the second rotation stop axially bored line grabs portion；Rotation stop part be provided with
The second through hole that external thread part coordinates, is provided with and multiple cooperations with card article and position relationship is one-to-one in the periphery of rotation stop part
Neck, vertically protrudes the second kink with the diameter parallel of the second through hole in the side of rotation stop part, and the second kink is towards the
Plane the 6th rotation prevention portion of formation of two through holes.
As the improvement of scheme one, the periphery at the two ends of the second through hole of rotation stop part is equipped with round ring boss.
As the improvement of scheme one, nut rotation stop set is sheet metal component.
As the improvement of scheme one, bolt is outer-hexagonal bolt, and the first rotation stop hole is inner hexagonal hole.
As the improvement of scheme one, nut is outer-hexagonal nut, and the second rotation stop hole is inner hexagonal hole.
As the improvement of scheme one, neck section is trapezoidal.
A kind of fastening structure of the locking fastening assembly comprising any one of scheme one to six, in addition to attached body and parent, it is attached
The attached body through hole that body coordinates provided with minimum of one with external thread part, parent is provided with position relationship is corresponding one by one with attached body through hole
With external thread part coordinate parent through hole；The external thread part of bolt sequentially pass through the first rotation stop hole, first through hole, attached body lead to
Hole, parent through hole, the second through hole is threadedly coupled with the internal thread hole of nut and the 3rd rotation prevention portion of the first kink is kept out attached
On the medial plane of body, the 6th rotation prevention portion of the second kink keep out on the medial plane of parent, bolt head is split into
In one rotation stop hole, together with bolt rotation stop set, attached body are closely attached by bolts and nuts with parent；The card article of nut rotation stop set
Towards rotation stop part by the second rotation stop borehole jack in the periphery of nut, card article is put in and by neck, and the hook portion of grabbing is kept out in rotation stop part
The axial limiting covered to nut rotation stop is formed on the end face of nut；First rotation prevention portion and the second rotation prevention portion, which coordinate, forbids bolt
Cover and relatively rotate with bolt rotation stop, the medial plane of the 3rd rotation prevention portion and attached body, which coordinates, forbids the relatively attached body of bolt rotation stop set to turn
Dynamic, the 4th rotation prevention portion coordinates with the 5th rotation prevention portion forbids nut and nut rotation stop to cover relative rotation, the 6th rotation prevention portion and parent
Medial plane, which coordinates, forbids rotation stop part to be rotated with respect to parent, and the relative rotation stop part turn of nut rotation stop part is forbidden in the cooperation of card article and neck
It is dynamic；Bolts and nuts are un-rotatably installed together attached body and parent.
As the improvement of scheme eight, attached body and two clamping plates that parent is respectively transmission line of electricity wire clamp.
The utility model has the advantages that：
The first rotation stop hole phase that bolt is covered through bolt rotation stop and its head and bolt rotation stop is covered by swivel bolt
Passed through after cooperation from one end of wire clamp, be then inserted in rotation stop part in the other end of wire clamp, and nut is tightened to nominal torque.Most
After the neck of the hook portion of the grabbing alignment rotation stop part for each half card article that nut rotation stop is covered afterwards, apply external force press-in.Because nut stops
The card article of pivoted housing, which has, opens the inner that rotation stop part is entered in the hook portion of grabbing after certain angle outside certain elasticity, card article.Thus, bolt because by
The limitation of bolt rotation stop set can not rotate；Nut rotation stop is covered because can not also be revolved by the stop of the neck of rotation stop part in circumferencial direction
Turn, so as to cause the nut being fitted together to therewith can not also rotate, so as to reach locking purpose.The utility model is simple in construction, easily
In implementation, and it is not required to change original bolt and nut, the economic benefits brought are considerable.
