Abstract
【課題】締結対象とボルトに螺合するナットをフィクスト状態にすることで緩み止めとするナット。また、ボルト側から螺合を緩めることで取り外せるナットを提供する。【解決手段】ナット座面下部外筒に雄ネジ（左ネジ）を設け、内筒は雌ネジ（右ネジ）のナットを、タップを設けた締結対象に螺合し、切穴貫通の締結対象のボルトとナットを螺合締結することでナットがフィクスト状態になり、左右の回転が固定され緩み止めとなる。従って、ボルトだけが螺合を緩めることができる。この緩み止めナットはワンウェイとなる。A nut that prevents loosening by setting a nut screwed to a fastening object and a bolt in a fixed state. Also, a nut that can be removed by loosening the screw from the bolt side is provided. [Solution] A male thread (left-hand thread) is provided on the outer cylinder at the bottom of the nut bearing surface, and the inner cylinder has a female-thread (right-hand thread) nut that is screwed into a fastening target provided with a tap, and a notched hole penetration fastening target By screwing the bolt and nut together, the nut becomes a fixed state, and the left and right rotation is fixed to prevent loosening. Therefore, only the bolt can be unscrewed. This locking nut is a one-way.
Description
本発明は、締結構造に関するものである。The present invention relates to a fastening structure.
特許文献１に記載されているように、代表図面による釣竿のリールシート部の緩みを７．緩み止めナット（右ネジ）と６．駆動ナット（左ネジ）の左右逆向きの圧接合の連れ周りにより、お互いの座面を強く押し合うことで緩みを阻止することが示されています。ダブルナットを始め二つのナットで緩み止めとしているものが比較的多く見られます。 As described in Patent Literature 1, the loosening of the reel seat portion of the fishing rod according to the representative drawings is described in 7. 6. locking nut (right hand thread); It has been shown that the rotation of the drive nut (left-handed screw) in the left-right opposite direction of the pressure joint prevents loosening by strongly pressing the bearing surfaces against each other. There are relatively many things that use two nuts to prevent loosening, including double nuts.
振動によるナットの緩み（回転）を右ネジと左ネジの二つのナットで防止するのではなく、単体のナットで締め付け回転方向を生かし、反対方向の緩み回転を止めることで緩みを防止することができる。 Loosening (rotation) of the nut due to vibration can be prevented by using two nuts, one with a right-handed thread and one with a left-handed thread, instead of using a single nut. can.
本発明は、ナット座面下部外筒に雄ネジ（左ネジ）を設け、タップ加工された締結対象に螺合することで左回転は止められ固定される。また、内筒は雌ネジ（右ネジ）であり、切穴貫通の締結対象のボルトに螺合し締結されて右回転も固定されフィクスト状態となる。従って振動による緩みの発生が止められる。また、ナットから螺合を緩めることは不可となりますが、ボルトの螺合を緩めていけばナットは外れます。また、ボルトをナット外筒の左ネジの長さ以上に緩めてから、ナットを右回転して締結対象から外し、続いて左回転すれば結び目を解くようにボルトから外れます。この緩み止めナットは締め付けのみのワンウェイとなる。（図１～３参照）上記、ボルトが左ネジの場合、ナット外筒が右ネジで内筒が左ネジで対応し、左右ネジの対称性が守られていれば同様である。 According to the present invention, a male screw (left-handed screw) is provided on the lower outer cylinder of the nut seating surface, and left-hand rotation is stopped and fixed by screwing it into a tapped fastening target. In addition, the inner cylinder is a female thread (right-hand thread), and is screwed and fastened to a bolt to be fastened through the cut hole, so that the right rotation is also fixed and it is in a fixed state. Therefore, loosening due to vibration can be prevented. Also, it is not possible to loosen the screw from the nut, but the nut can be removed by loosening the screw of the bolt. Also, after loosening the bolt by more than the length of the left-hand thread of the nut outer cylinder, turn the nut clockwise to remove it from the tightening target, and then turn it counterclockwise to remove it from the bolt as if untying the knot. This locking nut is a one-way tightening only. (Refer to FIGS. 1 to 3) When the bolt has a left-hand thread, the nut outer cylinder has a right-hand thread and the inner cylinder has a left-hand thread.
