Description
Rohranschluss Vorliegende Erfindung bezieht sich auf einen Rohranschluss.
Bekannte Rohranschlüsse weisen zwei koaxial zueinander liegende Hülsen, die gegeneinander dreh bar und gegeneinander begrenzt axial verschiebbar miteinander verbunden sind, auf.
Bei solchen Rohranschlüssen besitzt die eine Hülse ein Aussengewinde und die andere ein Innen gewinde, was sich nicht bewährt hat.
Gemäss vorliegender Erfindung weisen beide Hül sen je ein Innengewinde auf.
In der beiliegenden Zeichnung ist ein Rohr anschluss nach der Erfindung in einem Ausführungs beispiel dargestellt.
Der im Axialschnitt gezeichnete Rohranschluss weist eine zylindrische Hülse 1 aus Metall oder Kunst stoff auf, deren eines Ende mit einem Innengewinde 2 versehen ist. Anschliessend an das Gewinde 2 be sitzt die Hülse 1 einen Teil 3, dessen innerer Durch messer grösser als derjenige des Innengewindes 2 ist. Der Teil 3 ist an seinem freien Ende durch einen nach innen gerichteten Randwulst 4 abgeschlossen.
Der Rohranschluss weist eine zweite Hülse 5 auf, die koaxial zur Hülse 1 liegt und über einen Teil ihrer Länge mit einem Innengewinde 6 versehen ist, an das sich ein Teil 7 mit kleinerem Aussen durchmesser anschliesst. Ein Randwulst 8 mit grö sserem Durchmesser als der Aussendurchmesser des Teils 7 liegt im Teil 3 der Hülse 1. Auf diese Weise sind die beiden Hülsen 1 und 5 gegenein ander drehbar und gegeneinander in axialer Richtung begrenzt verschiebbar miteinander verbunden.
Der beschriebene Rohranschluss ist zum An schliessen eines Rohres an ein Apparategehäuse, einen elektrischen Schaltkasten, ein Verteilgehäuse und dergleichen verwendbar, die einen Gewindeanschluss- nippel aufweisen, der in das Gehäuse bzw. den Ka sten eingesetzt bzw. eingeschraubt ist. Der Rohr anschluss gestattet aber auch die Verbindung von zwei Rohrenden.
Pipe connection The present invention relates to a pipe connection.
Known pipe connections have two coaxial sleeves which are mutually rotatable bar and mutually limited axially displaceably connected to each other.
In such pipe connections, one sleeve has an external thread and the other has an internal thread, which has not proven successful.
According to the present invention, both sleeves each have an internal thread.
In the accompanying drawing, a pipe connection according to the invention is shown in an execution example.
The pipe connection shown in axial section has a cylindrical sleeve 1 made of metal or plastic, one end of which is provided with an internal thread 2. Subsequently to the thread 2 be the sleeve 1 sits a part 3, the inner diameter of which is greater than that of the internal thread 2. The part 3 is closed at its free end by an inwardly directed edge bead 4.
The pipe connection has a second sleeve 5 which is coaxial with the sleeve 1 and is provided over part of its length with an internal thread 6, to which a part 7 with a smaller external diameter is connected. A bead 8 with a larger diameter than the outer diameter of the part 7 is located in part 3 of the sleeve 1. In this way, the two sleeves 1 and 5 are mutually rotatable and mutually connected to one another in an axial direction to a limited extent.
The pipe connection described can be used to connect a pipe to an apparatus housing, an electrical switch box, a distributor housing and the like, which have a threaded connection nipple which is inserted or screwed into the housing or the box. The pipe connection also allows two pipe ends to be connected.
