(57) [Summary] (Correction) [Purpose] By improving the bolt head, it can be tightened with various tools, and at the same time it causes reaction force and biting action at the time of tightening to prevent loosening and reversion. Take preventive measures. [Structure] The groove (2) is provided on the lower contact surface of the bolt head (1), and the spring-like rib (3) is provided, and the upper part of the bolt head is provided. It is characterized in that a through hole is provided on the side surface of the head.
Description
【０００１】[0001]
この考案は、ボルト頭底にバネ状の刻みを入れ、ボルト頭を改良したねじに 関するものである。 This invention relates to a screw having a bolt head with a spring-like notch and an improved bolt head.
【０００２】[0002]
従来、ボルト底にスプリングワッシャーを入れて、ゆるみ止めとしていた。 Conventionally, a spring washer was put on the bottom of the bolt to prevent it from loosening.
【０００３】[0003]
これは次のような欠点があった。 （イ）ボルトにバネを通しては、ネジ止めとするために、大変面倒であった。 （ロ）ボルト頭部の型によって、締付器具が、限定されていた。 本考案は、これらの欠点を除くためになされたものである。 This had the following drawbacks. (A) It was very troublesome to pass the spring through the bolt to fix it with a screw. (B) The tightening device was limited by the type of bolt head. The present invention has been made to eliminate these drawbacks.
【０００４】[0004]
ボルト頭（１）の下部接触面に溝（２）を設け、ボルト頭（１）の上部に± の溝（４）を設ける。 そして、ボルト頭（１）の側面に穴（５）を設ける。 本考案は、以上のような構成よりなるボルトねじである。 A groove (2) is provided on the lower contact surface of the bolt head (1), and a groove (4) is formed on the upper portion of the bolt head (1). Then, a hole (5) is provided on the side surface of the bolt head (1). The present invention is a bolt screw having the above-described configuration.
【０００５】[0005]
ボルト頭（１）を±ドライバー又は、スパナでねじ穴に回転させて締めつけ る。すると、ボルト頭（１）の下部接触面のバネ状のリブ（３）が、反力を起 こして、緩み止め作用が働く。 Tighten the bolt head (1) by rotating it with a screwdriver or a wrench into the screw hole. Then, the spring-like ribs (3) on the lower contact surface of the bolt head (1) generate a reaction force, and the loosening prevention action works.
【０００６】[0006]
以下、本案の実施例について説明する。 （イ）ボルト頭（１）の下部接触面に溝（２）を設け、バネ状のリブ（３）を設 ける。 溝（４）を設ける。 （ハ）ボルト頭（１）の側面に締め付け穴（５）を設ける。 本案は以上のような構造で、これを使用するときは、±ドライバー又は、ボ ルト頭（１）の側面に締め付け穴（５）貫通棒又は、スパナにてねじ穴に回転 させて締めつける。すると、ボルト頭（１）の下部接触面のバネ状のリブ（３ ）が、反力を起こして、緩み止め作用が働く。 しかも締め付け材が、ボルトねじ材よりも硬度が、小さければ締め付け材が 、ボルト頭（１）の下部接触面の溝（２）に食い込み、逆戻りを防止する。Hereinafter, examples of the present invention will be described. (B) A groove (2) is provided on the lower contact surface of the bolt head (1) and a spring-like rib (3) is provided. A groove (4) is provided. (C) A tightening hole (5) is provided on the side surface of the bolt head (1). This proposal has the above-mentioned structure. When using this, tighten the screwdriver or the bolt head (1) to the side surface of the tightening hole (5) through rod or spanner to rotate it into the screw hole. Then, the spring-like ribs (3) on the lower contact surface of the bolt head (1) generate a reaction force, and the loosening prevention action works. Moreover, if the tightening material has a hardness lower than that of the bolt screw material, the tightening material bites into the groove (2) of the lower contact surface of the bolt head (1) to prevent the backward movement.
【０００７】[0007]
締め付けるだけで緩み止めが働き、±ドライバー又は、ボルト頭（１）の側 面に締め付け穴（５）貫通棒又は、スパナ等いろいろな締付器具にて、締め付 けができ、きわめてやさしく簡単である。 Locking works only by tightening, and it can be tightened with ± various kinds of tightening tools such as screwdriver or bolt head (1) side surface of tightening hole (5) through rod, spanner, etc. It is extremely easy and easy .
