〔考案の対象と利用分野〕
本考案は、管継手に関し、特に詳述すれば、管
とロツクリングとが同回転する共廻り現象を防止
させる管継手に関する。[Detailed Description of the Invention] [Object of the Invention and Field of Application] The present invention relates to a pipe joint, and more particularly, to a pipe joint that prevents a co-rotation phenomenon in which a pipe and a locking ring rotate at the same time.
本考案は、金属管や合成樹脂管の接続に利用さ
れ、又、継手自身を合成樹脂で製作される場合に
も利用される。 The present invention is used to connect metal pipes and synthetic resin pipes, and is also used when the joint itself is made of synthetic resin.

As shown in FIG. 1, a pipe fitting 1 is connected to a fitting body 2
It is known that the fitting is composed of a cap nut 3 screwed onto the joint body, a lock ring 4, a washer 5, and a packing 6 arranged inside the cap nut 3 and the joint body 2. In this pipe joint 1, by tightening the cap nut 3 to the joint body 2, the lock ring 4 is advanced, and the gasket 6 is pressed through the washer 5 to bring it into close contact with the pipe 7, and at the same time,
It functions to cause the claws on the inner peripheral surface of the lock ring 4 to bite into the tube surface.
このようにロツクリング４の管７への喰い込み
は、ロツクリング４と管７とが一体化するように
なる。このため、さらに袋ナツト３を締付ける
と、ロツクリングとワツシヤおよび袋ナツトとの
間の摩擦の違いから、袋ナツト３と一諸に管７も
回転することになる。このようないわゆる共廻り
現象は、既接続側の袋ナツトをゆるめたり、又、
曲管の場合には、その先端位置がずれることにな
り、位置合せができない。 In this way, when the lock ring 4 bites into the tube 7, the lock ring 4 and the tube 7 become integrated. Therefore, when the cap nut 3 is further tightened, the tube 7 rotates together with the cap nut 3 due to the difference in friction between the lock ring, the washer, and the cap nut. This so-called co-rotation phenomenon can be caused by loosening the cap nut on the already connected side, or by
In the case of a curved pipe, the position of its tip will shift, making alignment impossible.
本考案は、前述した従来技術の不具合を解消さ
せることを、その技術的課題とするもので、基本
的には、継手本体の端面と、該端面と向い合うロ
ツクリングの前面との何れか一方に突起を、且つ
他方に溝を設け、装着時該突起と溝とを係合させ

The technical problem of the present invention is to solve the above-mentioned problems of the prior art.Basically, the present invention is designed to solve the problem of the prior art described above. A technical means is adopted in which one protrusion is provided with a groove on the other, and the protrusion and the groove are engaged during installation.
本考案によれば、袋ナツトの継手本体への締付
けにより突起と溝とが係合するので、ロツクリン
グが管面に喰い込んだ状態で、さらに袋ナツトを
回転させても、ロツクリングと袋ナツトとの間で
すべりが生じ、管を回転させない。
According to the present invention, the protrusion and the groove engage when the cap nut is tightened to the joint body, so even if the cap nut is further rotated with the lock ring biting into the pipe surface, the lock ring and the cap nut will not move. Slip occurs between the tubes, preventing the tube from rotating.
本考案は、ロツクリングと継手本体への部分的
改良のみであるから、製造工程の変更はなく、安
価なものとなり、又、ロツクリングと継手本体の
合成樹脂による成形を可能とするものである。 Since the present invention involves only partial improvements to the lock ring and the joint body, there is no change in the manufacturing process, resulting in an inexpensive product, and also allows the lock ring and the joint body to be molded from synthetic resin.
(1) 突起を継手本体の端面に且つ溝をロツクリン
グの外周面に溝を形成する。
(1) Form a protrusion on the end surface of the joint body and a groove on the outer peripheral surface of the lock ring.
(2) ロツクリングの後端に開口するスリツトを設
ける。(2) Provide a slit that opens at the rear end of the lock ring.
(3) ロツクリングの前方に該ロツクリングと一体
にワツシヤを形成する。(3) A washer is formed integrally with the lock ring in front of the lock ring.
第２−４図を参照して本考案の実施例を説明す
る。
An embodiment of the present invention will be described with reference to FIGS. 2-4.
尚、従来例の説明と重複する部分は省略する。 Note that parts that overlap with the description of the conventional example will be omitted.
継手本体２の端面に後向きの突起８を設ける。
該突起８の係合を許容する形の溝９をロツクリン
グ４の外周面に形成する。第３図に示すように、
ロツクリング４の後端に開放されるスリツト１０

又、第３図の例の如く、ワツシヤ５をロツクリン
グ４と一体に成形してもよい。又、第４図に示す
如く、ロツクリング４と一体に成形されたワツシ
ヤ５の前面に突起８を設け、該突起８を継手本体
２の端面に形成した溝９に係合させてもよい。 A backward protrusion 8 is provided on the end face of the joint body 2.
A groove 9 is formed in the outer peripheral surface of the lock ring 4 to allow engagement with the projection 8. As shown in Figure 3,
Slit 10 opened at the rear end of lock ring 4
It is preferable to provide a lock ring 4 to facilitate inward elastic deformation of the lock ring 4 when tightening the nut 3, and to increase the biting of the lock ring 4 into the outer circumferential surface of the tube 7.
Further, as in the example shown in FIG. 3, the washer 5 may be molded integrally with the lock ring 4. Alternatively, as shown in FIG. 4, a projection 8 may be provided on the front surface of the washer 5 integrally formed with the lock ring 4, and the projection 8 may be engaged with a groove 9 formed on the end surface of the joint body 2.
