Description
【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、緩み止め状
態にするために、複数個のナツトを、ボルトに対して各
別に螺合するように形成し、しかも、各ナツトには、ボ
ルトに螺着するために、雌ネジ孔だけが形成してあった
。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ンド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
かかる欠点があった。However, in order to screw multiple Nandos onto the bolt,
Each nut must be screwed into a predetermined position from the tip of the bolt, which has the drawback that the assembly process takes a lot of time and effort.
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 screwed onto a bolt simply and quickly.
本発明のナツト構造の特徴構成は、3個以上のナツトを
同芯状に並べた状態で、かつ、隣接するものどうしが相
対回転する状態で連結し、前記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

そのボルトに対する前記ナツトの径方向への相対移動に
よって挿脱するための切欠きを、前記す・7トの全て及
びそれらナンドどうしを連結する連結部材に形成しであ
ることにあり、その作用効果は、次の通りである。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. At least two are connected in a state where relative movement in the radial direction is prevented, and a notch for inserting and removing a bolt for screwing the nut by relative movement in the radial direction of the nut with respect to the bolt, It is formed into a connecting member that connects all of the above-mentioned items and the items, and its functions and effects are as follows.
つまり、3個以上のす7)は、同芯状に並べた状態で連
結しであるために、ボルトに対して一体に組付は出来、
しかも、ボルトに組付けるのに、ナツトの全て及び連結
部材とに形成した切欠きを通してボルトの長手方向にお

的に回転させれば、各ナツトに形成した切欠きは、夫々
異なった方向に向くために、ボルトとナンドとの離脱が
阻止されると共に、ボルトにナンド全てが螺合して、隣
接するナツトどうしが緩み止め状態に締付は合える。In other words, since three or more pieces 7) are connected in a concentric manner, they cannot be assembled together with the bolt.
Furthermore, when assembling the nuts onto the bolt, the nuts can be assembled into the longitudinally intermediate portion of the bolt through the notches formed in all of the nuts and the connecting member, and each nut can be rotated relative to each other. The notches formed in the nuts face in different directions, which prevents the bolt from separating from the NAND, and also allows all the NANDs to screw onto the bolt, tightening adjacent nuts to prevent them from loosening. It fits.
その上、ナツトのうち互に離れて位置する少なくとも2

ルト(4)とナツト(1)を組付けできる。Moreover, at least two of the nuts are located apart from each other.
As shown in FIG. 4, the adjacent first and second
As the nuts (IA) and (IB) rotate relative to each other, each nut (IA) and (I
The third nut (IC) located away from the first nut (18) prevents the moment force (F) that tends to tilt in the radial direction on the notch (6) side of B) from acting. , bolt (4
The bolt (4) and nut (1) can be assembled with the axis of the nut (1) aligned with the axis of the bolt (4).
従って、3個以上のナツトを、ボルトの先端より所定位
置まで螺進しなくとも、切欠きを通してボルトの任意の
位置に迅速に組付けでき、しかも、緩み止め状態に簡単
にナツトどうしを締付けることができ、ボルトに対する
組付作業性を簡単に向上させることができた。その上、
ナンドの軸芯をボルトの軸芯に対して傾くことなく螺合
させられて、ボルトとナツトによる組付は精度を高く維
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. On top of that,
The axis of the NAND can be screwed together without tilting with respect to the axis of the bolt, and the assembly using bolts and nuts can maintain high accuracy.
