Abstract
Description
本発明は、ボルトの直径に段差を設け、締め付け六角ナットと緩み防止六角ナットをそれぞれの直径のボルトに逆回転で締め付けして、両方の六角ナットの緩みを防止した、緩み防止ボルトナットに関するものである。 The present invention relates to a loosening prevention bolt nut in which a step is provided in the diameter of the bolt, and the tightening hexagon nut and the loosening prevention hexagon nut are fastened to the bolts of respective diameters in reverse rotation to prevent the loosening of both hexagon nuts. It is.
従来、締め付けする本体と六角ナットとの間に座金を挟む、ダブル六角ナットを使用する等で、六角ナットの緩み防止を行っていた。 Conventionally, the hexagon nut has been prevented from loosening by sandwiching a washer between the main body to be tightened and the hexagon nut, or by using a double hex nut.
そのために、次のような問題点あった。
振動が激しい箇所に取り付けして長時間経過すると、緩みが発生する事があった。
本発明は、これらの問題点を解決するためになされたものである。Therefore, there were the following problems.
Looseness may occur when a long time has passed after installation in a place where vibration is intense.
The present invention has been made to solve these problems.
一本の丸鋼の直径に段差を設けて、内側の締め付けボルト部分を右回転ネジ山でネジ切りし、その締め付けボルト部分より直径を小さくした、外側の緩み防止ボルト部分を左回転ネジ山でネジ切りする。そして、締め付け六角ナットの調整筒側正面を粗くして凹凸をつけ、締め付けボルト部分に右回転でねじ込みし締め付けする。さらに、中空円柱型の調整筒の両方の六角ナット側正面を粗くして凹凸をつけ、ボルトの直径の段差をまたぐ位置に通す。最後に、緩み防止六角ナットの調整筒側正面を粗くして凹凸をつけ、緩み防止ボルト部分に左回転でねじ込みし締め付け、締め付けナットの面の凹凸と調整筒の面の凹凸、調整筒の面の凹凸と緩み防止ナットの面の凹凸をそれぞれ食い込ませる。以上を特徴とする緩み防止ボルトナットである。 Provide a step in the diameter of a single round steel bar, thread the inner tightening bolt part with the right rotation screw thread, and make the outer loosening prevention bolt part smaller in diameter than the tightening bolt part with the left rotation screw thread. Thread. Then, the front side of the adjustment cylinder side of the tightening hexagonal nut is roughened to make unevenness, and the tightening bolt portion is screwed clockwise to be tightened. Furthermore, the front surfaces of the hexagon nuts on both sides of the hollow cylinder type adjustment cylinder are roughened to be uneven, and are passed through a position across the step of the bolt diameter. Finally, roughen the front side of the adjustment cylinder side of the loosening prevention hex nut to make it uneven, and screw it into the anti-loosening bolt part by turning it counterclockwise to tighten it, the unevenness of the tightening nut surface, the unevenness of the adjustment cylinder surface, the surface of the adjustment cylinder The unevenness of the surface of the nut and the unevenness of the surface of the loosening prevention nut are bitten respectively. A loosening prevention bolt nut characterized by the above.
振動が激しい箇所に取り付けして長時間経過すると、振動により締め付け六角ナットが左回転して緩もうとする力を、両方の六角ナットと調製筒との接触面の凹凸の食い込みにより、緩み防止六角ナットに回転力が伝わり、緩み防止六角ナットが逆ネジのため締め付けられて緩もうする回転力を防止する。また、緩み防止六角ナットが右回転して緩もうとする力を、両方の六角ナットと調整筒との接触面の凹凸の食い込みにより、締め付け六角ナットに回転力が伝わり、締め付け六角ナットが逆ネジのため締め付けられて緩もうとする回転力を防止する。 If it is attached to a place where vibration is intense and a long time elapses, the tightening hex nut rotates counterclockwise due to vibration, and the hexagonal nut on the contact surface between both hex nuts and the preparation cylinder bites into the loosening prevention hexagon. The rotational force is transmitted to the nut, and the anti-loosening hexagon nut is tightened by a reverse screw to prevent the rotational force from loosening. In addition, the force that the loosening prevention hex nut rotates to the right will cause the rotational force to be transmitted to the tightening hex nut due to the unevenness of the contact surface between both hex nuts and the adjustment cylinder, and the tightening hex nut will reverse screw. Therefore, it prevents the rotational force that is tightened and loosened.
以下、本発明の実施の形態について説明する。
（イ）一本の丸鋼（１）の直径に段差を設けて、内側の締め付けボルト部分（２）を右回転ネジ山でネジ切りし、その締め付けボルト部分（２）より、直径を５ｍｍ程度小さくした、外側の緩み防止ボルト部分（３）を左回転ネジ山でネジ切りする。
（ロ）締め付け六角ナット（４）の調整筒（６）側正面を粗くして凹凸をつけ、締め付けボルト部分（２）に右回転でねじ込みし締め付けする。
（ハ）六角ナットより少し柔らかい材質の、中空円柱型で長さが２０ｍｍ程度の、調整筒（６）の両方の六角ナット側正面を粗くして凹凸をつけ、ボルトの直径の段差をまたぐ位置に通す。
（ニ）緩み防止六角ナット（５）の調整筒（６）側正面を粗くして凹凸をつけ、緩み防止ボルト部分（３）に左回転でねじ込みし締め付け、締め付けナットの面の凹凸と調整筒の面の凹凸、調整筒の面の凹凸と緩み防止ナットの面の凹凸をそれぞれ食い込ませる。
本発明は以上のような構成で、これを使用するときは、締め付けする２枚の鋼材にボルト穴をあけボルトを通して、締め付け六角ナット（４）を締め付けボルト部分（２）に右回転でねじ込み締め付けする。さらに、調整筒（６）をボルトの直径の段差をまたぐ位置に通して、緩み防止六角ナット（５）を緩み防止ボルト部分（３）に左回転でねじ込み、締め付け六角ナット（４）が回転しないようにスパナ等で抑えながら、調整筒（６）と両方の六角ナットの接触面の凹凸が食い込むまで緩み防止六角ナット（５）を左回転で締め付けする。Embodiments of the present invention will be described below.
(A) A step is provided in the diameter of one round steel (1), the inner tightening bolt part (2) is threaded with a right-hand screw thread, and the diameter of the tightening bolt part (2) is about 5 mm. Thread the smaller, loosening-off bolt part (3) on the outside with a counterclockwise thread.
(B) The tightening hexagon nut (4) is roughened on the front surface of the adjustment cylinder (6) side to make irregularities, and screwed into the tightening bolt part (2) by clockwise rotation and tightened.
(C) A position that straddles the step of the bolt diameter by roughening the front face of both sides of the adjustment cylinder (6), which is a hollow cylindrical type with a length of about 20 mm, made of a material that is slightly softer than the hexagon nut, Pass through.
(D) The loosening prevention hex nut (5) adjustment tube (6) side front is roughened to make unevenness, screwed into the anti-loosening bolt part (3) by turning counterclockwise and tightened, and the tightening nut surface unevenness and adjustment cylinder The surface of the adjustment cylinder, the surface of the adjustment cylinder, and the surface of the loosening prevention nut.
The present invention is configured as described above. When this is used, a bolt hole is drilled through two steel materials to be tightened, a bolt is passed through the bolt, and a tightening hex nut (4) is screwed into the tightening bolt portion (2) by rotating it clockwise. To do. Furthermore, the adjustment cylinder (6) is passed through a position across the step of the bolt diameter, and the loosening prevention hexagon nut (5) is screwed into the loosening prevention bolt part (3) by turning counterclockwise, and the tightening hexagon nut (4) does not rotate. While tightening with a wrench or the like, the loosening prevention hex nut (5) is tightened counterclockwise until the irregularities on the contact surfaces of the adjustment cylinder (6) and both hex nuts bite.
