【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ナツト構造に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to nut structures.
従来複数個のナツトをボルトに螺合させて、緩

Conventionally, in order to prevent loosening by threading a plurality of nuts onto a bolt, a plurality of nuts were formed to be threaded onto the bolt separately, and each nut had a thread attached to the bolt. Only a female screw hole was formed for screwing.
しかし、ボルトに複数個のナツトを螺着するた
めには、ボルトの先端より各ナツトを所定位置ま
で夫々螺進させていかなければならず、組付作業
に時間及び手間が多くかかる欠点があつた。
However, in order to screw multiple nuts onto a bolt, each nut must be screwed in from the tip of the bolt to a predetermined position, which has the disadvantage of requiring a lot of time and effort for assembly work. Ta.
本発明の目的は、ボルトに対して複数個のナツ
トを、簡単で迅速に螺着できるようにする点にあ
る。 An object of the present invention is to enable a plurality of nuts to be easily and quickly screwed onto a bolt.
本発明のナツト構造の特徴構成は、３個以上の

である。
The characteristic configuration of the nut structure of the present invention is that three or more nuts are arranged in a concentric manner and are connected in a state in which adjacent nuts rotate relative to each other, and the nuts are located apart from each other. A notch for connecting at least two pieces in a state in which relative movement in the radial direction is prevented, and for inserting and removing a bolt to which the nut is screwed together by moving the nut relative to the bolt in the radial direction. is formed on all of the nuts and the connecting member that connects the nuts together, and its effects are as follows.
つまり、３個以上のナツトは、同芯状に並べた
状態で連結してあるために、ボルトに対して一体
に組け付け出来、しかも、ボルトに組付けるの

締付け合える。
In other words, since three or more nuts are connected in a concentric manner, they can be assembled to the bolt as one unit, and all of the nuts and the connecting member must be assembled to the bolt. through the notch formed in the middle part of the bolt in the longitudinal direction,
When the nuts are assembled and rotated relative to each other, the notches formed in each nut face in different directions, which prevents the bolt from separating from the nut, and also prevents the bolt from separating. All nuts are screwed together, and adjacent nuts can be tightened to prevent loosening.
その上、ナツトのうち互に離れて位置する少な
くとも２個を、径方向への相対移動が阻止された
状態で連結してあるために、第４図に示すよう

で、ボルト４とナツト１を組付けできる。 Moreover, since at least two of the nuts located apart from each other are connected in a state where relative movement in the radial direction is prevented, the adjacent first and As the two nuts 1A and 1B rotate relative to each other, each nut 1 is attached to the bolt 4.
The third nut 1C, which is located apart from the first nut 1A, prevents the moment force F that tends to tilt in the radial direction on the notch 6 side of the nuts A and 1B, and causes the nut to tighten around the axis of the bolt 4. The bolt 4 and the nut 1 can be assembled with the axes of the bolts 4 and 1 aligned.
従つて、３個以上のナツトを、ボルトの先端よ

維持できる。
Therefore, three or more nuts can be quickly assembled to any position on the bolt through the notch without having to be screwed from the tip of the bolt to a predetermined position, and the nuts can be easily tightened to prevent loosening. This made it possible to easily improve the workability of assembling bolts. In addition, the nut can be screwed into the bolt without tilting its axis relative to the bolt axis, so that the bolt and nut can be assembled with high accuracy.
