【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、管を挿入・係止する継手本体と種々の機器
に取り付けるための取付用部材を別個に形成した後、両
者を接合・一体化して構成する管継手に関するものであ
る。[Detailed Description of the Invention] [Industrial field of application] This invention separately forms a joint body for inserting and locking a pipe and a mounting member for mounting to various devices, and then joins and integrates them. The present invention relates to a pipe joint that is configured by converting it into a pipe.
従来のこの種管継手は、継手本体は合成樹脂で作製され
ているが、機器に取り付けるためのネジ部を設けた取付
用部材は金属で作製されていた。これは、取付用部材を
継手本体に設けた嵌合孔に圧入して嵌合するのに、取付
用部材の外面に形成したエッジ部を継手本体の嵌合孔の
内壁面に食い込ませる必要があるため、合成樹脂で形成
するエッジ部の強度が不足するからである。In this type of conventional pipe joint, the joint body is made of synthetic resin, but the attachment member provided with the screw portion for attaching to the device is made of metal. This is because when the fitting member is press-fitted into the fitting hole provided in the fitting body to be fitted, the edge portion formed on the outer surface of the fitting member needs to bite into the inner wall surface of the fitting hole of the fitting body. Therefore, the strength of the edge portion formed of the synthetic resin is insufficient.
また、継手本体と取付用部材を別個に作製せず、合成樹
脂により一体成形によって作製したものも知られてい
た。Further, it has been known that the joint body and the mounting member are not separately produced, but are integrally formed of synthetic resin.
しかし、取付用部材が金属で作られていると、中に流す
薬品の種類によっては取付用部材が腐食して中に流す薬
品が変質する等の問題があるため、管継手全体を合成樹
脂によって作ることが望ましい。しかしながら、取付用
部材を合成樹脂で作って従来と同様にエッジ部を形成す
ると、エッジ部の強度が十分でないため、圧入して嵌合
した際にエッジ部が継手本体の壁面に食い込むことがで
きず、十分な接合強度が得られなかった。However, if the mounting member is made of metal, there is a problem that the mounting member will corrode and the chemical that flows inside will change depending on the type of chemical flowing inside. It is desirable to make. However, if the mounting member is made of synthetic resin and the edge portion is formed as in the conventional case, the strength of the edge portion is not sufficient, so the edge portion can dig into the wall surface of the joint body when press-fitting and fitting. No sufficient bonding strength was obtained.
また、前記従来の管継手では、継手本体に取付用部材が
固着され、あるいは両者が成形により一体化されている
ため、両者の相対的な回動は不可能であり、機器に取り
付けたときに継手本体の管接続用の開口の向きを調節す
ることができず、非常に不便であった。Further, in the above-mentioned conventional pipe joint, since the mounting member is fixed to the joint body or both are integrated by molding, it is impossible to rotate the both relative to each other. It was very inconvenient because the direction of the opening for connecting the pipe of the joint body could not be adjusted.
そこで、この考案の目的は、優れた耐薬品性を持つと共
に軽量であり、しかも継手本体と取付用部材とが十分な
強度で接合される管継手を提供することである。Therefore, an object of the present invention is to provide a pipe joint which has excellent chemical resistance and is lightweight, and in which the joint body and the mounting member are joined with sufficient strength.
この考案の他の目的は、取付用部材に対して継手本体が
その中心軸の周りに回動可能な管継手を提供することで
ある。Another object of the present invention is to provide a pipe joint in which the joint body is rotatable around its central axis with respect to the mounting member.
そこで、この考案は、上記目的を達成するために次のよ
うな技術的手段を講じた管継手としている。Therefore, the present invention provides a pipe joint in which the following technical measures are taken to achieve the above object.

側面を開口側に形成した係合溝を有する嵌合孔を設け、
他方に透孔の軸に対して直角で無端環状の平面からなる
側面を開口と反対側に形成した係合突起を有する前記嵌
合孔に嵌合可能な突出部が設ける。That is, the joint body and the mounting member are made of synthetic resin, and one of the joint body and the mounting member has a side surface that is perpendicular to the axis of the through hole and is a flat surface of an endless ring on the opening side. Providing a fitting hole with the formed engagement groove,
On the other hand, there is provided a projecting portion which can be fitted into the fitting hole and which has an engaging projection having a side surface which is perpendicular to the axis of the through hole and is formed of an endless annular flat surface on the side opposite to the opening.
さらに、前記突出部を前記嵌合孔に圧入して、前記突出
部の係合突起を、前記嵌合孔の係合溝に係合させる。Further, the protrusion is press-fitted into the fitting hole, and the engagement protrusion of the protrusion is engaged with the engagement groove of the fitting hole.

好ましい。When the fitting hole is provided in the joint body, the protrusion is provided in the attachment member, and when the fitting hole is provided in the attachment member, the protrusion is provided in the joint body. The engagement protrusions are preferably slidable in the annular engagement groove.
継手本体及び取付用部材のいずれも合成樹脂により形成

設けた嵌合孔に、他方に設けた突出部を圧入すると、突
出部の係合突起が嵌合孔の内壁を押し広げて中に入り、
互いに嵌合する。Since both the joint body and the mounting member are made of synthetic resin and have flexibility, when the protrusion provided on the other side is press-fitted into the fitting hole provided on either side, the protrusion Of the engaging projections spreads the inner wall of the fitting hole and goes inside,
Fit together.
このとき、前記係合突起は嵌合孔に形成した係合溝に係
