Description
【０００１】[0001]
この考案は、植込みボルトの回り止め装置に関する。 This invention relates to a locking device for a stud.
【０００２】[0002]
従来、この種の植込みボルトの回り止め装置は、被締付部材の挿通孔を挿通し て雌ねじ部材のねじ孔に螺合する一方のねじ部と、被締付部材からの突出端部に ナットを螺合する他方のねじ部が同一方向のねじ方向とされ、上記ナットを回り 止め手段にて回り止めした構成が知られている。 Conventionally, this type of locking device for studs has one screw part that is inserted into the insertion hole of the member to be screwed and screwed into the screw hole of the female screw member, and the nut at the end protruding from the member to be tightened. There is known a configuration in which the other threaded portion that is screwed with is made to have the same threading direction, and the nut is prevented from rotating by a rotation stopping means.
【０００３】[0003]
この従来構造のものにおいては、植込みボルトの一方のねじ部と他方のねじ部 とが同一ねじ方向でかつ同一ピッチに形成されているため、振動等が作用した場 合にナットに回り止めが施しているとはいえ、ボルトが回って抜け出やすいとい う問題があった。 そこで、この考案の目的は、上記のような技術課題を解決し、植込みボルトの 確実な回り止めが達成できる回り止め装置を提供することにある。 In this conventional structure, one screw part of the stud and the other screw part are formed in the same screw direction and at the same pitch. However, there was a problem that the bolt turned around and easily slipped out. Therefore, an object of the present invention is to solve the above technical problems and to provide a detent device that can achieve a definite detent of the stud.
【０００４】[0004]
上記目的を達成するため、この考案は、被締付部材の挿通孔を挿通して雌ねじ 部材のねじ孔に螺合する一方のねじ部と、被締付部材からの突出端部にナットを 螺合する他方のねじ部が同一方向のねじ方向とされ、上記ナットを回り止め手段 にて回り止めした植込みボルトの回り止め装置であって、ねじ孔に螺合する上記 一方のねじ部のねじピッチをナットを螺合する上記他方のねじ部のねじピッチよ りも小としたことを特徴とする。 In order to achieve the above-mentioned object, the present invention inserts a nut into a projecting end portion of a threaded member and one threaded portion which is inserted into an insertion hole of a member to be fastened and screwed into a threaded hole of a female screw member. A locking device for an implant bolt, in which the other screw part to be mated has the same screw direction, and the nut is prevented from rotating by a rotation stopping means, and the screw pitch of the one screw part to be screwed into the screw hole. Is smaller than the thread pitch of the other threaded portion on which the nut is screwed.
【０００５】[0005]
上記構成によれば、振動等でボルトが回り出そうとして抜け出る方向にボルト が回転しようとしても、ねじ孔に螺合するねじ部のねじピッチがナットを螺合す るねじ部のねじピッチよりも小さいため、そのピッチ差によりボルトがナットに 対して回転することがなく、ボルトが抜け出ることがない。 According to the above configuration, even if the bolt tries to come out due to vibration or the like and is rotated in the direction of coming out, the screw pitch of the screw part screwed into the screw hole is larger than the screw pitch of the screw part screwed with the nut. Since it is small, the bolt will not rotate with respect to the nut due to the pitch difference, and the bolt will not come out.
【０００６】[0006]
以下、この考案の具体的実施例について図面を参照して説明する。 Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings.
【０００７】 図１にこの考案の植込みボルトの回り止め装置の実施例を示す。１は植込みボ ルトで、被締付部材２の挿通孔２１を挿通して、一方の端部に形成したねじ部１ １が雌ねじ部材３のねじ孔３１に螺合されている。また、被締付部材２から突出 する側の上記ボルト１の他方の端部にはねじ部１２が形成され、ナット４が螺合 されている。上記ボルト１の一方のねじ部１１と他方のねじ部１２とは、同一方 向のねじ部とされるとともに、一方のねじ部１１のねじピッチが他方のねじ部１ ２のねじピッチよりも小さく形成されている。さらに、上記ボルト１の両ねじ部 １１，１２間にはねじが形成されていない中間軸１３とされている。この中間軸 １３の径は上記一方のねじ部１１のねじ山の径と同一かそれよりも大きく形成さ れている。これにより、ボルト１の一方のねじ部１１を雌ねじ部材３のねじ孔３ １に螺合させたとき、中間軸１３の端部１４が上記ねじ孔３１に当接してそれ以 上のボルト１の雌ねじ部材３へのねじ込みが防止されるようにされている。FIG. 1 shows an embodiment of a locking device for a stud according to the present invention. Reference numeral 1 denotes an implant bolt, which is inserted through the insertion hole 21 of the member to be tightened 2 and the screw portion 11 formed at one end is screwed into the screw hole 31 of the female screw member 3. A screw portion 12 is formed at the other end of the bolt 1 on the side protruding from the member to be fastened 2, and a nut 4 is screwed into the screw portion 12. The one screw part 11 and the other screw part 12 of the bolt 1 are screw parts in the same direction, and the screw pitch of one screw part 11 is smaller than the screw pitch of the other screw part 12. Has been formed. Further, an intermediate shaft 13 having no screw is formed between the screw parts 11 and 12 of the bolt 1. The diameter of the intermediate shaft 13 is formed to be equal to or larger than the diameter of the screw thread of the one screw portion 11. As a result, when one screw portion 11 of the bolt 1 is screwed into the screw hole 31 of the female screw member 3, the end portion 14 of the intermediate shaft 13 comes into contact with the screw hole 31 and the other bolts 1 of the bolt 1 above it are screwed. Screwing into the female screw member 3 is prevented.
【０００８】 また、ナット４と被締付部材２との間には、ロックプレート５が介装されてお り、ロックプレート５の一部５１がナット４の側面４１に沿うように折曲されて いる。さらにロックプレート５は図２に示すように、植込みボルト１の複数本、 例えば図２の２本にわたって一枚の共通したプレートで形成されている。上記構 成によりナット４はロックプレート５により回り止めされている。 なお、ロックプレート５の回り止めは、図２の方法に限らず、溶接等他の方法 にて行うことができる。A lock plate 5 is interposed between the nut 4 and the tightened member 2, and a part 51 of the lock plate 5 is bent along the side surface 41 of the nut 4. ing. Further, as shown in FIG. 2, the lock plate 5 is formed of a plurality of studs 1, for example, two studs 1 shown in FIG. With the above structure, the nut 4 is prevented from rotating by the lock plate 5. The locking of the lock plate 5 is not limited to the method shown in FIG. 2 and can be performed by another method such as welding.
【０００９】[0009]
【考案の効果】 以上から明らかなように、この考案の植込みボルトの回り止め装置においては 、振動等により植込みボルトがねじ孔から緩んで抜け出ようとしてボルトが回転 しようとしても、ボルトのナット側のねじ部のねじピッチより雌ねじ部材側のね じ部のねじピッチの方が小さく形成されているため、ねじピッチの差により、ボ ルトとナットの螺合状態の緩みが防止され、その結果ボルトの回り止めが達成さ れる。EFFECTS OF THE INVENTION As is apparent from the above, in the locking device for the stud of the present invention, even if the stud is loosened from the screw hole due to vibration or the like, and the stud is trying to rotate, the nut side Since the thread pitch of the thread on the female thread side is smaller than the thread pitch of the thread, the looseness of the threaded state between the bolt and the nut is prevented due to the difference in thread pitch. A detent is achieved.
