Abstract

PROBLEM TO BE SOLVED: To provide a bolt with a double lock type nut capable of solving the problem that for conventional bolts with a nut, the nut easily loosens with vibration or time course.SOLUTION: A bolt with a double lock type nut is configured such that slit is provided along a vertical center line of a bolt, further a screw hole is provided vertically at a slit center part, and after the bolt is fastened with a nut, the screw is inserted and screwed into the screw hole, thereby making the bolt and nut into a state of locking to each other to prevent the fastened nut from loosening; and also when the nut is loosened, the inserted screw is removed to enable looseness simply and reliably.SELECTED DRAWING: Figure 1

Description

本発明はナット付きボルトに関するものである。 The present invention relates to a bolt with a nut.

従来、ボルト式ネジはナットで締めるものが主流であった。 Conventionally, bolt-type screws have been tightened with nuts.

従来のナット付きボルトは、振動や時間経過等と共にナットが緩みやすかった。しかし適切な防止策がないため、これらを防ぐ事が難しかった。ナットの緩みが重大なトラブルの原因になる恐れが常にあった。
本発明は、以上の問題点を解決するためになされたものである。Conventional bolts with nuts are easy to loosen with vibration and time. However, it was difficult to prevent these because there was no appropriate preventive measure. There has always been a risk that the loosening of the nut could cause serious trouble.
The present invention has been made to solve the above problems.

ボルトの縦中心線に沿ってスリットを設け、更にスリット中心と中心を共有するネジ穴を縦に設け、ボルトをナットで締めた後にそのネジ穴にネジを挿入し締めることにより、外から締めるナットと内側から押し拡がるボルトとの相互ロック状態が生じ、締めたナットが緩みにくくなる。またナットを緩める際には挿入したネジを取り出す事により簡単・確実に行う事ができる。
以上を特徴とするダブルロック式ナット付きボルトである。A nut to be tightened from the outside by providing a slit along the vertical center line of the bolt, further providing a screw hole that shares the center with the center of the slit, and tightening the bolt with a nut and then inserting and tightening the screw into the screw hole And a bolt that spreads from the inner side, and the tightened nut is difficult to loosen. Also, when loosening the nut, it can be done easily and reliably by removing the inserted screw.
This is a bolt with a double lock nut characterized by the above.

ボルトをナットで締めた後にそのネジ穴にネジを挿入しボルトを押し拡げてダブルロック状態になって、締めたナットが緩みにくくなり、またナットを緩める際には挿入したネジを取り出す事により簡単・確実に行う事ができる。 After tightening the bolt with a nut, insert the screw into its screw hole and expand the bolt to double lock state, making it difficult to loosen the tightened nut, and when loosening the nut, it is easy to take out the inserted screw・ Can be done reliably.

ボルト（１）の中心線に縦にスリット（４）を設け、更にスリット中央部にネジ穴（５）を縦に設けボルト（１）をナット（２）で締めた後にそのネジ穴（５）にネジ（３）を挿入し締める。そうすることにより、締めたナット（２）が緩みにくくなる。またナット（２）を緩める際には、挿入したネジ（３）を取り出す事により簡単・確実に行う事が可能になる。
尚、スリット（４）やネジ穴（５）は同様であっても、ボルト（１）の外観形状を根元から先端へ徐々に細く形成し、ネジ穴（５）にネジ（３）を装着した際にスリット（４）が拡げられボルト（１）の外壁面が垂直状態に近くなる様に形成されてもよい。A slit (4) is provided vertically in the center line of the bolt (1), a screw hole (5) is provided vertically in the center of the slit, and the bolt (1) is tightened with a nut (2). Insert and tighten the screw (3). By doing so, the tightened nut (2) becomes difficult to loosen. Further, when loosening the nut (2), it is possible to easily and surely remove the inserted screw (3).
Although the slit (4) and the screw hole (5) are the same, the external shape of the bolt (1) is gradually narrowed from the root to the tip, and the screw (3) is attached to the screw hole (5). In this case, the slit (4) may be widened so that the outer wall surface of the bolt (1) is close to a vertical state.

Claims

A slit is provided along the vertical center line of the bolt, and a screw hole that shares the center with the slit center is provided vertically. After tightening the bolt with a nut, the screw is inserted into the screw hole to move the bolt from the inside to the outside. Double-locked nut bolts that are double-locked with strong expansion, making it difficult to loosen the tightened nuts and removing the inserted screws when loosening the nuts.
