Abstract

PROBLEM TO BE SOLVED: To provide a lock nut in which a nut and a washer are integrated, which can be fasten by a hand to the brink of adhesion even in a tilted or narrow hard-to mount location such as a roof without dropping of a washer, having no resistance and is capable of being mounted manually, and then mounted by tools such as a wrench.SOLUTION: The lock nut includes: a groove provided in a lower part (1) of a nut; a swaging tube; and an angled washer (2), where they are integrated by being swaged.SELECTED DRAWING: Figure 7

Description

この発明は、ナットの底部に角度の付いた座金を付けたゆるみ止めナットである。The present invention is a locking nut having an angled washer at the bottom of the nut.

従来のゆるめ止めナットは、上部に板バネを装着した物と又２個使用した物がある。There are two types of conventional locking nuts, one with a leaf spring mounted on the top and the other with two used.

これは、次の様な欠点があった。
従来、ナット１個で上部に板バネを挿入した物は、締め付け時から板バネの抵抗があり、手で密着寸前まで締め付けられず、スパナ等の工具が必要、２回目使用時は板バネが成形されている為、ゆるみ止め効果が弱くなる。又、従来ナット２個使用の物は、２回締付けなければならず作業時間が倍になり重量も２個分になる。座金に角度を付けている為、応力が上下だけでなく横にも働きゆるみ効果も増す。
本発明は、以上の様な欠点をなくす為になされた物である。This has the following drawbacks.
Conventionally, a leaf spring inserted at the top with a single nut has resistance from the leaf spring from the time of tightening, and cannot be tightened to the point of close contact by hand, and a tool such as a wrench is required. Since it is molded, the loosening prevention effect is weakened. In addition, a conventional product using two nuts has to be tightened twice, and the working time is doubled and the weight is also two. Since the washer is angled, the stress acts not only on the top and bottom but also on the side, increasing the loosening effect.
The present invention has been made to eliminate the above disadvantages.

Means to solve the problem

ナットの底部（１）に角度の付いた座金（２）を設ける。
本発明は、以上の構成によりなるゆるみ止めナットである。An angled washer (2) is provided at the bottom (1) of the nut.
The present invention is a locking nut having the above-described configuration.

Effect of the invention

ナットと座金が一体となっているので、一回ずつ座金の挿入を省け上向きに取り付け時狭い場所での取付時座金が落下する事がない。
又、密着寸前まで抵抗がないので手で締め付けられ、スパナ等の使用が短時間で済む。
今迄のナット１個で板バネを挿入している場合、最初から板バネの抵抗がありボルトに挿入時からスパナ等の工具が必要で、密着寸前まで手で絞められない。
２回目使用時は挿入している板バネが１回目で形成されている為ロック効果が弱くなる。
ナット２個使用の物は２回締め付けなければならず作業性が悪く、重量がナット２個分になる。本発明は、座金に角度を付けている為ゆるみ止め効果が上下だけでなく、横にも発生するので倍の応力が働き、ゆるみ止め効果を増す。
何度繰り返し使用してもゆるみ止め効果は落ちない。
振動試験機でテスト、結果はゆるみません。Since the nut and washer are integrated, the washer is not inserted once, and the washer is not dropped when installed in a narrow place when installed upward.
In addition, since there is no resistance until just before contact, it is tightened by hand, and the use of a spanner or the like is short.
When a leaf spring is inserted with a single nut so far, the resistance of the leaf spring is present from the beginning, and a tool such as a spanner is required from the time of insertion into the bolt, and it cannot be tightened by hand until just before contact.
At the time of the second use, since the inserted leaf spring is formed at the first time, the locking effect is weakened.
An object using two nuts must be tightened twice, resulting in poor workability and a weight equivalent to two nuts. In the present invention, since the washer is angled, the anti-loosening effect is generated not only on the top and bottom but also on the side, so that double stress acts and the anti-loosening effect is increased.
Even if it is used over and over, the anti-loosening effect will not drop.
Test with vibration tester, results will not loosen.
