Description

この発明は雄ネジ体と雌ネジ体が噛み合っているものが振動や衝撃等を受けても締結状態から緩みを生じないはずのねじの緩み止めが、ひとりでに緩みを生じて雄ネジ体から雌ネジ体が抜け出すことを防止するものであって、その使用範囲として宇宙航空ロケットや新幹線などを含む電気、機械、建築、関連等の構造物に使用することのできるネジのロック機構に関するものである。   The present invention is designed to prevent loosening of a screw that should not loosen from a fastened state when a male screw body and a female screw body are engaged with each other even when subjected to vibration or impact. The present invention relates to a screw locking mechanism that can be used for electrical, mechanical, architectural, and related structures including aerospace rockets and bullet trains as a range of use.

従来において、雄ネジと雌ネジが噛み合って緩み防止手段が取入れられたものはいろいろあるが、その中でも本発明に近い技術として、下記特許文献１から６などがある。   Conventionally, there are various types in which a male screw and a female screw are engaged with each other and a loosening prevention means is incorporated. Among them, techniques close to the present invention include Patent Documents 1 to 6 below.

特許文献１は雌ネジに取付けられた緩み止め防止板が雄ネジに弾性変形しながら付着して締付けられて入ってゆくために、最初から締付に大きなトルクを要しながら締付けるので締付け作業が困難になり、又、充分な緩み防止のストッパーとなる力には至らず緩み側にも容易に回るために強力な緩み防止とはならない、又、構造が複雑になり製造コストが高くなる欠点を有する。   In Patent Document 1, since the anti-loosening plate attached to the female screw adheres to the male screw while being elastically deformed and is tightened, tightening requires a large torque from the beginning. It becomes difficult, and it does not reach the force to be a stopper to prevent sufficient loosening, but it also turns easily on the loose side, so it does not become strong loosening prevention, and the structure becomes complicated and the manufacturing cost increases. Have.

又、特許文献２は締付面と取付部材の間の両者に硬質の部材を食い込ませることによる両者間の移動を規制し回り止めの作用を得るものであるが、食い込む硬質部材を支える部分が柔らかでなければならないので、硬質部材が倒れたりするので両者間に隙間が発生し易く、又、プラスチックやゴム等の軟質座金は経時変化等でボロボロになるのでそれらを含めると緩み止め防止としては欠点を有するものである。   In addition, Patent Document 2 regulates the movement between the fastening surface and the mounting member by biting a hard member between them, and obtains the effect of rotation prevention. Since it must be soft, the hard member falls down, so a gap is likely to occur between them, and soft washers such as plastic and rubber become tattered with changes over time etc. It has a drawback.

特許文献３と４については雄ネジに取付部材とナット、又は、座金を通した後、その側面をもう一つのナットに突起部を設けた突起部をナット又は座金のネジ穴に押圧することで、突起部が雄ネジに巻き込まれる摩擦力で緩み止め効果を高める狙いを計ったものであるが、このものは突起部の特に外径方向の寸法に対しその中に入るナット又は座金の寸法が適度でないと入らなくなり、取付部材との間に隙間を生じてしまう。   For Patent Documents 3 and 4, after passing a mounting member and a nut or a washer through a male screw, the side surface of the other nut is provided with a protrusion on the other side, and the protrusion is pressed into the screw hole of the nut or washer. The projecting part is designed to increase the locking effect by the frictional force with which the projecting part is wound on the external thread. This is because the dimension of the nut or washer that enters the projecting part in particular with respect to the dimension in the outer diameter direction. If it is not appropriate, it will not enter, and a gap will be formed between the mounting member.

又、ナット又は座金に食い込ませる突起部の外径方向の寸法を大きくするとナット又は座金に食い込みにくくなり、例えば、食い込んでも突起部が厚いと変形しにくくなる。逆に、突起部が薄いと回り防止となる摩擦力が発生しにくくなる欠点を有するものである。   In addition, if the dimension of the protruding portion that bites into the nut or the washer is increased, it becomes difficult to bite into the nut or the washer. For example, if the protruding portion is thick, it is difficult to deform. On the contrary, if the protrusion is thin, it has a drawback that it is difficult to generate a frictional force that prevents rotation.

それらの従来の背景技術にはそれぞれの欠点を有し緩み止め防止として充分な効果を発揮する技術とはいえないものであった。   These conventional background arts have their respective drawbacks and cannot be said to be a technique that exhibits a sufficient effect for preventing loosening.

特許文献５は本特許願出願人が既に出願しているもので従来の欠点を解決するために発明したものであるが、この欠点は雌ネジ体にロック棒を使用することで、構造が複雑になって生産性が悪くなる欠点を有している。   Patent Document 5 has been filed by the applicant of the present patent application and was invented to solve the conventional drawbacks. However, this disadvantage is complicated by using a lock rod for the female screw body. Therefore, there is a drawback that productivity becomes worse.

特許文献６は、この公知例の明細書で明らかのよぅに、この出願人は第１ナットの凸と第２ナットの凹との一部を偏心させて組み合わせることにより緩み止め効果を発揮する緩み止めダブルナットを発明しているが、このものはこの公知例で明らかにしているように、この偏心のダブルナットは嵌合した後に偏心嵌合部分に微小の隙間が存在する、そのためそれらを解決する手段として、偏心方向他側に樹脂或は軟質金属を被覆にすることで、その欠点を補い解決使用としたものであるが、その受ける応力に充分に対処できる充分な強度と構造を有するものではない。   As is apparent from the specification of this known example, Patent Document 6 discloses a loosening effect that prevents the loosening effect by combining the convexity of the first nut and the concaveity of the second nut in an eccentric manner. Invented a stop double nut, but as shown in this known example, this eccentric double nut has a minute gap in the eccentric fitting part after fitting, so it solves them As a means to do this, the other side of the eccentric direction is covered with resin or soft metal to compensate for the drawbacks, but it has sufficient strength and structure to sufficiently cope with the stress is not.

又、この公知例でも明らかにしているように、締付け作用が雄ネジの径が熱膨張した時などでは一般に使用しているダブルナットの緩み止め効果より劣ることが発生するもので、樹脂或は軟質金属で補強しても充分とは云えない欠点を有するものである。   In addition, as is clear from this known example, when the diameter of the male screw is thermally expanded, the tightening action may be inferior to the loosening prevention effect of the commonly used double nut. Even if it is reinforced with a soft metal, it has a drawback that cannot be said to be sufficient.

この発明は雄ネジ体に締結部材を通して締結部材を雌ネジ体で締付けたものが緩むことを防止するものとしての雌ネジ体は実用上及び発明考案はいろいろあるが、それらは緩み止めとして充分なものとは言えず個々の欠点を有している。   In this invention, there are various types of female screw bodies that prevent loosening of a fastening member that is passed through a male screw body and tightened with a female screw body in practice, but they are sufficient to prevent loosening. It cannot be said that it has individual drawbacks.

背景技術で説明したように、ネジのロック機構は緩み止めとして充分な緩み止めの機能を発揮するものはなく、何らかの欠点を有するものである。   As described in the background art, there is no screw locking mechanism that exhibits a sufficient locking function as a locking mechanism and has some drawbacks.

従って、この発明の目的は背景技術のそれぞれの欠点を解決することができる確かな機能を発揮するネジのロック機構を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a screw locking mechanism that exhibits a certain function capable of solving the respective drawbacks of the background art.

前記目的の第一の発明は、締結部材を雄ネジ体と雌ネジ体で締付けることにおいて、一つの雌ネジ体はネジ部とそのネジ部を構成する外形部を有した外形部の一部の側壁を凸出部として複数割に分割したスリットを設けて、もう一つの雌ネジ体はネジ部と外形部の側壁をテーパによって形成する凹部を有した、前記二つの雌ネジ体を雄ネジ体に組み合わせて通して、この二つの雌ネジ体で締結部材を締付けることを特徴としたネジのロック機構によって達成される。   The first invention of the object is to tighten a fastening member with a male screw body and a female screw body, wherein one female screw body is a part of an outer shape portion having a screw portion and an outer shape portion constituting the screw portion. Provided with slits that are divided into a plurality of portions with the side wall as a protruding portion, and the other female screw body has a concave portion that forms the side wall of the screw portion and the outer shape by a taper. And a screw locking mechanism characterized in that the fastening member is fastened by the two female screw bodies.

前記目的の第二の発明は、締結部材を雄ネジ体と雌ネジ体で締付けることにおいて、一つの雌ネジ体はネジ部とそのネジ部を構成する外形部を有した外形部の一部の側壁を凸出部として複数割に分割したスリットを設けて、もう一つはテーパによって形成する凹部を有したワッシャ体とを雄ネジ体に組み合わせて通して、前記雌ネジ体によって締結部材を締付けることを特徴としたネジのロック機構によって達成される。   According to a second aspect of the present invention, when the fastening member is tightened with a male screw body and a female screw body, one female screw body is a part of the outer shape portion having a screw portion and an outer shape portion constituting the screw portion. A slit that is divided into a plurality of portions with the side wall as a protruding portion is provided, and the other is passed through a washer body having a recess formed by a taper in combination with a male screw body, and the fastening member is tightened by the female screw body This is achieved by a screw locking mechanism.

前記目的の第三の発明は、特許請求範囲の請求項１乃至請求項２において、凸出部に溝を設けて前記凸出部がたわみ易くしたことを特徴とするネジのロック機構によって達成される。   A third invention of the object is achieved by a screw locking mechanism according to claim 1 or 2, wherein a groove is provided in the protruding portion so that the protruding portion is easily bent. The

この発明は締結部材に雄ネジ体Ａを通して、二つの雌ネジ体で締付した雌ネジ体が緩みを生じないようにしたネジのロック機構の発明であって、締結部材に雄ネジ体Ａを通した雄ネジ体Ａに、一つはネジ部を形成する外形部の側壁をテ―パによって形成する凹部を設けた雌ネジ体Ｘと、その凹部に向き合って締結される、もう一つはネジ部を形成する外形部の側壁の凸出部を分割した複数個のスリットを設けた雌ネジ体Ｙとを組み合わせて雄ネジ体Ａに通して締結作用を発生させるものである。   The present invention is an invention of a screw locking mechanism in which a male screw body A is passed through a fastening member so that the female screw body fastened with two female screw bodies does not loosen, and the male screw body A is attached to the fastening member. One threaded male screw body A is fastened with a female screw body X provided with a recess formed with a taper on the side wall of the outer shape forming the threaded portion, and facing the recess. A combination of the female screw body Y provided with a plurality of slits obtained by dividing the protruding portion of the side wall of the outer shape part forming the screw part is passed through the male screw body A to generate a fastening action.

このように雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込み入れと、雌ネジ体Ｘのネジ部と雌ネジ体Ｙのネジ部は一般のダブルナットの緩み止め効果と同じように作用して緩み止め効果を発揮するものであるが、ここで異なるのは凹部に凸出部が入り込むことによって、凸出部を分割した複数個のスリットを設けた雌ネジ体Ｙのネジ部が雌ネジ体Ｘの凹部によって加締めるように雄ネジ体Ａのネジ部に固着することで雌ネジ体Ｘと雌ネジ体Ｙのネジのロック機構が得られるものである。   Thus, when the protruding portion of the female screw body Y is screwed into the concave portion of the female screw body X, the screw portion of the female screw body X and the screw portion of the female screw body Y are the same as the loosening prevention effect of a general double nut. However, the difference here is that the screw of the female screw body Y is provided with a plurality of slits that divide the protruding portion by the protruding portion entering the recessed portion. The screw locking mechanism of the female screw body X and the female screw body Y is obtained by adhering to the screw portion of the male screw body A so that the portion is caulked by the concave portion of the female screw body X.

雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込み入れる条件としては、いろいろな案件が考えられるが、雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込んでゆくと、凸出部が分割して複数個のスリットになっているので凸出部のネジ部が径方向の隙間分だけ曲がるようになるので、よって凸出部がたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとして雌ネジ体Ｘの凹部で雌ネジ体Ｙの凸出部を締付ける分があり、これらを締付けることによって雌ネジ体Ｘと雌ネジ体Ｙとによって雄ネジ体Ａのネジ部に凸出部のネジ部が加締めるように固着することができる加締作用と二つの雌ネジ体Ｘと雌ネジ体Ｙによってダブルナットの締付効果によって強力なネジのロック機構を得ることができるものである。   Various conditions are conceivable as conditions for screwing the protruding portion of the female screw body Y into the concave portion of the female screw body X, but the protruding portion of the female screw body Y is screwed into the concave portion of the female screw body X. As a result, since the protruding portion is divided into a plurality of slits, the screw portion of the protruding portion bends by the radial gap, so that the protruding portion is bent and deformed, and the screw The gap between the meshing directions of the female screw body is tightened, but as a final tightening, there is a part of tightening the protruding portion of the female screw body Y at the concave portion of the female screw body X, and by tightening these, The female screw body X and the female screw body Y can be fixed so that the threaded portion of the protruding portion is fastened to the threaded portion of the male screw body A, and the two female screw bodies X and the female screw body Y With a double nut tightening effect, a strong screw locking mechanism can be obtained. Is shall.

次の発明は、締結部材に雄ネジ体Ａを通した雄ネジ体Ａに、一つは貫通穴を形成する外形部の側壁をテ―パによって形成する凹部を設けたワッシャ体Ｃの凹部に向き合って締結される、もう一つはネジ部を形成する外形部の側壁をテーパによって形成する凸出部を分割して複数個のスリットを設けた雌ネジ体Ｚとを組み合わせて雄ネジ体Ａに通して締結作用を発生させるものである。   In the next invention, a male screw body A having a male screw body A passed through a fastening member, and a concave portion of a washer body C provided with a concave portion in which a side wall of an outer shape forming a through hole is formed by a taper. The other is fastened face to face, and the other is a male screw body A in combination with a female screw body Z provided with a plurality of slits by dividing a protruding portion formed by a taper on the side wall of the outer shape forming the screw portion. And a fastening action is generated.

ワッシャ体Ｃの凹部に雌ネジ体Ｚの凸出部をネジ込み入れる条件としては、いろいろな案件が考えられるが、ワッシャ体Ｃの凹部に雌ネジ体Ｚの凸出部をネジ込んでゆくと、凸出部が分割して複数個のスリットになっているので凸出部のネジ部が径方向の隙間分だけ曲がるようになるので、よって凸出部がたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとしてワッシャ体Ｃの凹部で雌ネジ体Ｚの凸出部を締付ける分があり、これらを締付けることによってワッシャ体Ｃと雌ネジ体Ｚとによって雄ネジ体Ａのネジ部に凸出部のネジ部が加締めるように固着することができる加締作用の締付効果によって強力なネジのロック機構が得られるものである。   As a condition for screwing the protruding portion of the female screw body Z into the recess of the washer body C, various cases are conceivable, but when the protruding portion of the female screw body Z is screwed into the recess of the washer body C, Since the protruding portion is divided into a plurality of slits, the screw portion of the protruding portion bends by the radial gap, so that the protruding portion bends and deforms, and the engagement of the screw However, as a final tightening, there is a part for tightening the protruding portion of the female screw body Z at the concave portion of the washer body C. By tightening these, the washer body C is tightened. And a female screw body Z can be secured to the threaded portion of the male threaded body A so that the threaded portion of the projecting portion is crimped, thereby providing a strong screw locking mechanism. is there.

この発明の加締作用は雌ネジ体Ｙの凸出部を加締めるように加圧してたわみを生じさせるので、その加圧部の反力によって凸出部は他の凹部と強く圧接する力が働くので緩みを生じなくなる力が発生するものである。   Since the caulking action of the present invention causes a deflection by pressurizing the protruding portion of the female screw body Y, the reaction force of the pressing portion causes a force that strongly presses the other recessed portion. Since it works, a force that does not cause looseness is generated.

従って、このネジのロック機構はネジ部に加わる加締作用とダブルナット作用の効果により熱作用などの環境条件の変化にも対応できる極めて有効な効果を発揮するものである。   Therefore, this screw locking mechanism exhibits a very effective effect that can cope with a change in environmental conditions such as a thermal action by the effect of the caulking action and the double nut action applied to the screw portion.

この発明は装置のようなもので二つで締付部を構成している内、片方を装置の一部に始めから取入れた物に、他方の一つを組み入れても成り立つもので、一つはネジ部とそのネジ部を構成する外形部を有した外形部の一部の側壁を凸出部として複数割に分割したスリットを設けてあれば、これまでの発明で前記に述べてきたようなネジのロック機構が得られるものである。   The present invention is like an apparatus, and the fastening part is composed of two parts, and one of the other parts is incorporated into the part of the apparatus that is incorporated from the beginning, and the other is incorporated. As described above in the invention so far, if the slit part divided into a plurality of parts is provided with the side wall of the external part having the external part constituting the screw part and the external part constituting the screw part as a protruding part A screw locking mechanism can be obtained.

この発明は締結部材を雄ネジ体Ａを通して二つの雌ネジ体で締付したしたものが緩みを生じないようにしたネジのロック機構の発明である。   This invention is an invention of a screw locking mechanism in which a fastening member tightened with two female screw bodies through a male screw body A does not cause loosening.

発明の第一は、締結部材に雄ネジ体Ａを通した雄ネジ体Ａに、一つはネジ部を形成する外形部の側壁にテ―パによって形成した凹部を設けた雌ネジ体Ｘの凹部に向き合って締結される、もう一つはネジ部を形成する外形部の側壁の凸出部を分割した複数個のスリットを設けた雌ネジ体Ｙとを組み合わせて雄ネジ体Ａに通して締結作用を発生させるものである。   The first aspect of the invention is an internal thread body A in which a male thread body A is passed through a fastening member, one of which is a female thread body X provided with a recess formed by a taper on the side wall of the outer shape forming the thread section. The other is fastened to face the concave portion, and the other is combined with the female screw body Y provided with a plurality of slits obtained by dividing the protruding portion of the side wall of the outer shape forming the screw portion, and passed through the male screw body A. The fastening action is generated.

締結は始めに雌ネジ体Ｘを回しながら締付けて締結部材を締付けるもので、この締結が終了後、この締結が緩まないように、雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込み入れることで締結が成り立つものである。   The fastening is performed by first tightening the female screw body X while turning the fastening member to tighten the fastening member. After the fastening, the protruding portion of the female screw body Y is provided in the concave portion of the female screw body X so that the fastening is not loosened. Fastening is achieved by screwing in.

このように雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込み入れと、雌ネジ体Ｘのネジ部と雌ネジ体Ｙのネジ部は一般のダブルナットの緩み止め効果と同じように作用して緩み止め効果を発揮するものであるが、ここで異なるのは凹部に凸出部が入り込むことによって、凸出部を分割した複数個のスリットを設けた雌ネジ体Ｙの凸出部のネジ部を雌ネジ体Ｘの凹部によって加締めるように雄ネジ体Ａのネジ部に固着することで雌ネジ体Ｘと雌ネジ体Ｙのネジのロック機構となるものである。   Thus, when the protruding portion of the female screw body Y is screwed into the concave portion of the female screw body X, the screw portion of the female screw body X and the screw portion of the female screw body Y are the same as the loosening prevention effect of a general double nut. However, the difference here is that the protruding portion of the female screw body Y provided with a plurality of slits dividing the protruding portion is provided by the protruding portion entering the recessed portion. The screw portion of the female screw body X and the female screw body Y becomes a locking mechanism of the female screw body X by fixing the protruding screw portion to the screw portion of the male screw body A so as to be crimped by the concave portion of the female screw body X.

雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込み入れる条件としては、いろいろな案件が考えられるが、雌ネジ体Ｘの凹部に雌ネジ体Ｙの凸出部をネジ込んでゆくと、凸出部が分割して複数個のスリットになっているので凸出部のネジ部が径方向の隙間分だけ曲がるようになるもので、よって凸出部がたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとして雌ネジ体Ｘの凹部で雌ネジ体Ｙの凸出部を締付ける分があり、これらを締付けることによって雌ネジ体Ｘと雌ネジ体Ｙとによって雄ネジ体Ａのネジ部に凸出部のネジ部が加締めるように固着することができる加締作用とダブルナットの締付効果によって強力なネジのロック機構を得ることができる。   Various conditions are conceivable as conditions for screwing the protruding portion of the female screw body Y into the concave portion of the female screw body X, but the protruding portion of the female screw body Y is screwed into the concave portion of the female screw body X. Eventually, since the protruding part is divided into a plurality of slits, the threaded part of the protruding part is bent by the gap in the radial direction, so that the protruding part is bent and deformed, The gap between the screw meshing directions will be tightened, but there is also a part that tightens the protruding part of the female screw body Y with the concave part of the female screw body X as the final tightening, and tighten these By using the female screw body X and the female screw body Y, the screw portion of the male screw body A can be fastened so that the screw portion of the protruding portion can be fastened, and the tightening effect of the double nut can tighten the screw. Can be obtained.

雌ネジ体Ｘと雌ネジ体Ｙの側壁の上部の隙間は全く無く締めて着止することもできるが、隙間を空けて設けることもできるものである。   Although there is no gap between the upper portions of the side walls of the female screw body X and the female screw body Y, it can be fastened and fixed, but it can also be provided with a gap.

従って、隙間を設けるか否かはそのときの条件による雌ネジ体Ｘと雌ネジ体Ｙの締付けをどのようにするかによってもネジのロック機構が得られるものである。   Therefore, whether or not the gap is provided can provide a screw locking mechanism depending on how the female screw body X and the female screw body Y are tightened according to the conditions at that time.

発明の第二は、締結部材に雄ネジ体Ａを通した雄ネジ体Ａに一つは貫通穴を形成する外形部の側壁をテ―パによって形成する凹部を設けたワッシャ体Ｃに、ワッシャ体Ｃの凹部に向き合って締結される、もう一つはネジ部を形成する外形部の側壁を凸出部とする凸出部を分割して複数個のスリットを設けた雌ネジ体Ｚを組み合わせて雄ネジ体Ａに通して締結作用を発生させるものである。   In the second aspect of the invention, the washer body C is provided with a recess formed by forming a side wall of an outer shape portion with a taper in the male screw body A through which the male screw body A is passed through the fastening member. The other is combined with the female screw body Z provided with a plurality of slits by dividing the protruding portion with the side wall of the outer shape forming the screw portion as the protruding portion. Thus, the fastening action is generated through the male screw body A.

締結は始めに雌ネジ体Ｘを回しながら締付けて締結部材を締付けるもので、この締結が終了後、この締結が緩まないように、ワッシャ体Ｃの凹部に雌ネジ体Ｚの凸出部をネジ込み入れることで締結が成り立つものである。   The fastening is performed by first tightening the female screw body X while turning the female screw body X to tighten the fastening member. After this fastening is completed, the protruding portion of the female screw body Z is screwed into the recess of the washer body C so that the fastening is not loosened. The conclusion can be established by putting it in.

凹部に凸出部が入り込むことによって、テーパによって形成する凸出部を分割した複数個のスリットを設けた雌ネジ体Ｚのネジ部をワッシャ体Ｃの凹部によって加締めるようになり雄ネジ体Ａのネジ部に固着させることで雌ネジ体Ｚのネジのロック機構が得られるものである。   When the protruding portion enters the recessed portion, the threaded portion of the female screw body Z provided with a plurality of slits obtained by dividing the protruding portion formed by the taper is swaged by the recessed portion of the washer body C, and the male screw body A The screw locking mechanism of the female screw body Z can be obtained by adhering to the screw portion.

ワッシャ体Ｃの凹部に雌ネジ体Ｚの凸出部をネジ込み入れる条件としては、いろいろな案件が考えられるが、ワッシャ体Ｃの凹部に雌ネジ体Ｚの凸出部をネジ込んでゆくと、凸出部が分割して複数個のスリットになっているので凸出部のネジ部が径方向の隙間分だけ曲がるようになるもので、よってたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとしてワッシャ体Ｃの凹部で雌ネジ体Ｚの凸出部を締付ける分があり、これらを締付けることによってワッシャ体Ｃと雌ネジ体Ｚとによって雄ネジ体Ａのネジ部に凸出部のネジ部が加締めるように固着することができる加締作用の締付効果によって強力なネジのロック機構が得られるものである。   As a condition for screwing the protruding portion of the female screw body Z into the recess of the washer body C, various cases are conceivable, but when the protruding portion of the female screw body Z is screwed into the recess of the washer body C, The protruding portion is divided into a plurality of slits so that the screw portion of the protruding portion bends by a gap in the radial direction, and therefore, between the amount of deformation and the meshing direction of the screw However, as a final tightening, there is a part for tightening the protruding portion of the female screw body Z at the concave portion of the washer body C. By tightening these, the washer body C and the female screw are tightened. A strong screw locking mechanism can be obtained by the tightening effect of the caulking action that can be fixed so that the threaded portion of the protruding portion is caulked to the threaded portion of the male screw body A by the body Z.

側壁の上部の隙間は全く無く締めて着止することもできるが、隙間を空けて設けることもできるものである。   Although there is no gap at the top of the side wall and it can be fastened and fixed, it can also be provided with a gap.

従って、隙間を設けるか否かはそのときの条件による雌ネジ体Ｚとワッシャ体Ｃによってネジのロック機構が得られるものである。   Therefore, whether or not to provide a gap is obtained by a screw locking mechanism by the female screw body Z and the washer body C according to the conditions at that time.

本発明を図示に従って説明すると、図１は締結部材Ｇに雄ネジ体Ａを通した雄ネジ体Ａに、一つはネジ部５を形成する外形部６の側壁にテ―パ８で凹部７を設けた雌ネジ体Ｘの凹７に向き合って締結される、もう一つのネジ部１５を形成する外形部１６の側壁をテーパ１８にした凸出部１７を分割させたスリット２０を設けた雌ネジ体Ｙとによって、雌ネジ体Ｘと雌ネジ体Ｙとを組み合わせて雄ネジ体Ａに通してネジのロック機構を構成する。 The present invention will be described with reference to the drawings. FIG. 1 shows a male screw body A in which a male screw body A is passed through a fastening member G. One is a recess 7 with a taper 8 on a side wall of an outer shape portion 6 forming a screw portion 5. A female provided with a slit 20 in which a projecting portion 17 having a tapered side wall of an outer shape portion 16 forming another screw portion 15 which is fastened facing the concave portion 7 of the female screw body X provided with a slit 18 is divided. The screw body Y and the female screw body X and the female screw body Y are combined and passed through the male screw body A to constitute a screw locking mechanism.

締結は始めに雌ネジ体Ｘを回しながら締付けて締結部材を締付けるもので、この締結が終了後、この締結が緩まないように、雌ネジ体Ｘの凹部７に雌ネジ体Ｙの凸出部１７をネジ込み入れることで締結が成り立つものである。   The fastening is performed by first tightening the fastening member while turning the female screw body X, and after the fastening is finished, the protruding portion of the female screw body Y is formed in the concave portion 7 of the female screw body X so that the fastening is not loosened. Fastening can be achieved by screwing 17 in.

このように雌ネジ体Ｘの凹部７に雌ネジ体Ｙの凸出部１７をネジ込み入れと、雌ネジ体Ｘのネジ部５と雌ネジ体Ｙのネジ部１５は一般のダブルナットの緩み止め効果と同じように作用して緩み止め効果を発揮するものであるが、ここで異なるのは凹部７に凸出部１７が入り込むことによって、テーパ１８によって形成する凸出部１７を分割するスリット２０で成る雌ネジ体Ｙのネジ部１５を雌ネジ体Ｘの凹部７によって加締めるように、雄ネジ体Ａのネジ部１９に固着させることで雌ネジ体Ｘと雌ネジ体Ｙのネジのロック機構を得るものである。   Thus, when the protruding portion 17 of the female screw body Y is screwed into the concave portion 7 of the female screw body X, the screw portion 5 of the female screw body X and the screw portion 15 of the female screw body Y are loosened from a general double nut. Although it acts in the same way as the stopping effect and exhibits the locking effect, the difference here is that the protruding portion 17 formed by the taper 18 is divided by the protruding portion 17 entering the recessed portion 7. The screw portion 15 of the female screw body Y is fixed to the screw portion 19 of the male screw body A so that the screw portion 15 of the female screw body X is caulked by the concave portion 7 of the female screw body X. A lock mechanism is obtained.

雌ネジ体Ｘの凹部７に雌ネジ体Ｙの凸出部１７をネジ込み入れる条件としては、いろいろな案件が考えられるが、雌ネジ体Ｘの凹部７に雌ネジ体Ｙの凸出部１７をネジ込んでゆくと、凸出部１７が分割したスリット２０になっているので凸出部のネジ部が径方向の隙間分だけたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとして雌ネジ体Ｘの凹部で雌ネジ体Ｙの凸出部１７を締付ける分があり、これらを締付けることによって雌ネジ体Ｘと雌ネジ体Ｙとによって雄ネジ体Ａのネジ部１９に凸出部１７のネジ部１５が加締めるように固着することができる加締作用と二つの雌ネジ体Ｘと雌ネジ体Ｙによってダブルナットの締付効果を有した強力なネジのロック機構を得るものである。   As a condition for screwing the protruding portion 17 of the female screw body Y into the concave portion 7 of the female screw body X, various cases can be considered, but the protruding portion 17 of the female screw body Y is inserted into the concave portion 7 of the female screw body X. When the screw is screwed in, the protruding portion 17 is divided into slits 20, so that the screw portion of the protruding portion is bent and deformed by the gap in the radial direction, and the gap portion between the meshing directions of the screws. However, as a final tightening, there is a portion for tightening the protruding portion 17 of the female screw body Y with the concave portion of the female screw body X. By tightening these, the female screw body X and the female screw body are tightened. The screw portion 15 of the protruding portion 17 can be fastened to the screw portion 19 of the male screw body A by Y, and the double nut can be tightened by the two female screw bodies X and the female screw body Y. A strong screw locking mechanism having an attaching effect is obtained.

雌ネジ体Ｘと雌ネジ体Ｙの側壁の上部の隙間３０は図２のように全く無く締めて着止することもできるが、隙間３０を空けて設けることもできるものである。   The gap 30 at the upper part of the side wall of the female screw body X and the female screw body Y can be completely tightened and fixed as shown in FIG. 2, but the gap 30 can also be provided.

従って、隙間３０を設けるか否かはそのときの使用条件による雌ネジ体Ｘと雌ネジ体Ｙの締付けによってネジのロック機構となるものである。   Therefore, whether or not the gap 30 is provided is a screw locking mechanism by tightening the female screw body X and the female screw body Y according to the use conditions at that time.

図８は本発明の応用例その一であって、この応用例は図１とは雌ネジ体Ｙの形状が異なるもので、ネジ部４５の外形部４６の側壁に設ける凸出部４７を形成する周囲に溝４４を設けて、凸出部４７のネジ部４５が全体にたわみ易くして、雌ネジ体Ｘの凹部２７に雌ネジ体Ｙの凸出部４７をネジ込み入れる条件で雄ネジ体Ａのネジ部１９に凸出部４７のネジ部４５が強力に固着するようにするものである。   FIG. 8 shows an application example of the present invention. This application example is different from FIG. 1 in the shape of the female screw body Y, and a protruding portion 47 provided on the side wall of the outer portion 46 of the screw portion 45 is formed. A groove 44 is provided in the periphery to make the screw portion 45 of the protruding portion 47 easy to bend as a whole, and the protruding portion 47 of the female screw body Y is screwed into the concave portion 27 of the female screw body X. The screw portion 45 of the protruding portion 47 is firmly fixed to the screw portion 19 of the body A.

この例では凸出部４７の角４２に若干のテーパを設けてあるが、凸出部４７の角はテーパを設けなくもよく丸みを設けてあればよいものである。   In this example, a slight taper is provided at the corner 42 of the protruding portion 47. However, the corner of the protruding portion 47 does not need to be provided with a taper and may be rounded.

図９は本発明の応用例その二であって、この応用例は雌ネジ体Ｘの凹部３７と雌ネジ体Ｙの凸出部５７のテーパ３８とテーパ５８とが全く同じか、若干異なるものを締付けても、この発明は成り立つことを示すものであって、凸出部５７のテーパ５８の部分を曲がり易くするために溝５４を設けたものである。   FIG. 9 shows a second application example of the present invention. In this application example, the concave portion 37 of the female screw body X and the taper 38 and the taper 58 of the protruding portion 57 of the female screw body Y are the same or slightly different. This indicates that the present invention can be achieved even if tightened, and a groove 54 is provided in order to make the tapered portion 58 of the protruding portion 57 easier to bend.

この例ではテーパ３８はネジ部３５まで設けたものを示すものである。   In this example, the taper 38 is provided up to the screw portion 35.

図１０は本発明の応用例その三であって、締結部材を締付けるのにこれまでとは逆に、雌ネジ体Ｙで締結部材を締付けておいて、雌ネジ体Ｙの凸出部を雌ネジ体Ｘの凹部で加締めるように雄ネジ体Ａのネジ部に固着させるもので、この変形例は雌ネジ体Ｙの凸出部を雌ネジ体Ｘで締付けるものである。   FIG. 10 shows a third application example of the present invention. Contrary to the conventional case, the fastening member is fastened with the female screw body Y, and the protruding portion of the female screw body Y is connected to the female part. In this modification, the protruding portion of the female screw body Y is fastened with the female screw body X.

図１０は図１から図９で説明してきたものとは異なり、雌ネジ体Ｙは外形を丸型として工具取付部８３を設けて凸出部８７を六つのスリット２０によって分割したもので、このように分割する数を増すことにより、凸出部８７がたわみ易くなり雌ネジ体Ｘの凹部７７で締付けた時に雄ネジ体Ａのネジ部１９に加締めるように強力に固着し易くすることができるようにしたものである。   FIG. 10 differs from what has been described with reference to FIGS. 1 to 9 in that the female screw body Y has a round outer shape and is provided with a tool mounting portion 83 and the protruding portion 87 is divided by six slits 20. By increasing the number of divisions in this way, the protruding portion 87 can be easily bent and can be firmly fixed so as to be caulked to the screw portion 19 of the male screw body A when tightened by the concave portion 77 of the female screw body X. It is something that can be done.

このように雌ネジ体Ｙを後から雌ネジ体Ｘで締付けても雌ネジ体Ｘは雌ネジ体Ｙの凸出部に加締めるように固着させることができるのでネジが緩む如何なる使用条件がひとりでに加わっても抜け出すことのないネジのロック機構を得られるものである。   In this way, even if the female screw body Y is tightened later with the female screw body X, the female screw body X can be fixed to the projecting portion of the female screw body Y so that the screw can be loosened. It is possible to obtain a screw locking mechanism that does not come out even if it is added.

図１３は本発明の応用例その四であって、締結部材に雄ネジ体Ａを通した雄ネジ体Ａに一つは貫通穴１０５を形成する外形部１０６をテ―パ１０８によって形成する凹部１０７を設けたワッシャ体Ｃの凹部１０７に向き合って締結される、もう一つはネジ部１１５を形成する外形部１１６の側壁を形成する凸出部１１７の角１１２にはテーパを設けなくてもよいが、凸出部１１７を分割させたスリット２０によって成る雌ネジ体Ｚを組み合わせて雄ネジ体Ａに通して締結作用を発生させるものである。   FIG. 13 shows the fourth application example of the present invention, in which a male screw body A is passed through a fastening member, and one of the male screw bodies A is a concave portion in which an outer shape portion 106 for forming a through hole 105 is formed by a taper 108. The other side of the washer body C provided with 107 is fastened to face the concave portion 107, and the other is not provided with a taper at the corner 112 of the protruding portion 117 forming the side wall of the outer shape portion 116 forming the screw portion 115. Although it is good, the female screw body Z formed by the slit 20 into which the protruding portion 117 is divided is combined and passed through the male screw body A to generate a fastening action.

締結は始めに雌ネジ体Ｘを回しながら締付けて締結部材を締付けるもので、この締結が終了後緩まないように、ワッシャ体Ｃの凹部１０７に雌ネジ体Ｚの凸出部１１７をネジ込み入れることで締結が成り立つものである。   Fastening is performed by first tightening the female screw body X while turning it to tighten the fastening member. The protruding portion 117 of the female screw body Z is screwed into the concave portion 107 of the washer body C so that the fastening member does not loosen after the fastening is completed. This is the conclusion.

凹部１０７に凸出部１１７が入り込むことによって、角１１２によって形成する凸出部１１７を分割するスリット２０によってなる雌ネジ体Ｚのネジ部１１５がワッシャ体Ｃの凹部１０７によって加締めるように雄ネジ体Ａのネジ部１９に固着させることで雌ネジ体Ｚのネジのロック機構となるものである。   As the protruding portion 117 enters the recessed portion 107, the male thread Z of the female screw body Z formed by the slit 20 that divides the protruding portion 117 formed by the corner 112 is caulked by the recessed portion 107 of the washer body C. By fixing to the screw part 19 of the body A, a screw locking mechanism of the female screw body Z is obtained.

ワッシャ体Ｃの凹部１０７に雌ネジ体Ａの凸出部１１７をねじ込み入れる条件としては、いろいろな案件が考えられるが、ワッシャ体Ｃの凹部１０７に雌ネジ体Ｚの凸出部１１７をねじ込んでゆくと、凸出部１０７が分割して複数個のスリットになっているので、凸出部１１７のネジ部が径方向の隙間分だけ曲がるようになるので、よって凸出部がたわみ変形する分と、ネジの噛み合い方向の間の隙間分とが締付しろとなるが、更に、最終的な締付けとしてワッシャ体Ｃの凹部１０７で雌ネジ体Ｚの凸出部１１７を締付ける分があり、これらを締付けることによってワッシャ体Ｃと雌ネジ体Ｚとによって雄ネジＡのネジ部１０９に凸出部１１７のネジ部が加締めるように固着することができる加締作用の締付効果によって強力なネジのロック機構とすることができる。   Various conditions are conceivable for screwing the protruding portion 117 of the female screw body A into the concave portion 107 of the washer body C, but the protruding portion 117 of the female screw body Z is screwed into the concave portion 107 of the washer body C. Eventually, since the protruding portion 107 is divided into a plurality of slits, the threaded portion of the protruding portion 117 bends by a gap in the radial direction, so that the protruding portion is bent and deformed. And the clearance between the screw meshing directions can be tightened, and there is a part for tightening the protruding portion 117 of the female screw body Z with the concave portion 107 of the washer body C as final tightening. By tightening the screw, the washer body C and the female screw body Z can fix the screw portion of the protruding portion 117 to the screw portion 109 of the male screw A so that the screw portion is tightened. Lock It can be configured.

側壁の上部の隙間５０は無く締めて着止することもできるが、隙間５０を空けて設けることもできるものである。 The gap 50 at the upper part of the side wall can be fastened and fixed, but the gap 50 can be provided.

従って、隙間５０を設けるか否かはそのときの使用条件によるもので雌ネジ体Ｚとワッシャ体Ｃによってネジのロック機構となるものである。   Therefore, whether or not the gap 50 is provided depends on the use conditions at that time, and the female screw body Z and the washer body C serve as a screw locking mechanism.

この発明の加締作用は雌ネジ体Ｙの凸出部を加締めるように加圧してたわみを生じさせるので、その加圧部の反力によって凸出部は他の凹部と強く圧接する力が働くので緩みを生じなくなる力が発生するものである。   Since the caulking action of the present invention causes a deflection by pressurizing the protruding portion of the female screw body Y, the reaction force of the pressing portion causes a force that strongly presses the other recessed portion. Since it works, a force that does not cause looseness is generated.

この発明は装置のようなもので二つで締付部を構成している内、片方を装置の一部に始めから取入れた物に、他方の一つを組み入れても成り立つもので、一つはネジ部とそのネジ部を構成する外形部を有した外形部の一部の側壁を凸出部として複数割に分割したスリットを設けてあれば、これまでの発明で前記に述べてきたようなネジのロック機構が得られるものである。   The present invention is like an apparatus, and the fastening part is composed of two parts, and one of the other parts is incorporated into the part of the apparatus that is incorporated from the beginning, and the other is incorporated. As described above in the invention so far, if the slit part divided into a plurality of parts is provided with the side wall of the external part having the external part constituting the screw part and the external part constituting the screw part as a protruding part A screw locking mechanism can be obtained.

この発明でのネジのロック機構は主に鉄やステンレスなどの材質でなり、ネジ部に加わる加締作用とダブルナット作用の効果により熱作用などの環境条件の変化にも対応できる極めて有効な機能を発揮するものである。   The screw lock mechanism in this invention is mainly made of materials such as iron and stainless steel, and it is a very effective function that can respond to changes in environmental conditions such as thermal action due to the effect of crimping action and double nut action applied to the screw part To demonstrate.
