Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Halten und Abdichten eines Rohres in einem Armaturenanschluss oder Fitting nach den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a device for holding and sealing a pipe in a fitting connection or fitting according to the features of the preamble of
Vorrichtungen der eingangs genannten Art finden Anwendung zur Montage von Armaturen mit Rohranschlüssen oder Rohrstutzen an flexiblen Schlauchleitungen sowie zur Erstellung von Kupferrohrinstallationen. Im Gegensatz zu Schraubverbindungen wie zum Beispiel Klemm-Quetsch-Verschraubungen ermöglichen die Vorrichtungen eine weitgehend werkzeugfreie Montage von Rohranschlüssen. Hierzu ist das Rohrende dichtend in die Vorrichtung eingesteckt und gegen Herausziehen gesichert.Devices of the type mentioned are used for mounting fittings with pipe connections or pipe sockets on flexible hose assemblies and for the creation of copper pipe installations. In contrast to screw connections such as clamp-crimp fittings, the devices allow a largely tool-free installation of pipe connections. For this purpose, the pipe end is sealingly inserted into the device and secured against pulling out.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Halten und Abdichten eines Rohres in einem Armaturenanschluss oder Fitting zu schaffen, bei der die Gefahr eines Umklappens der Federsegmente reduziert ist und gleichzeitig die Widerstandskraft gegen ein herausziehen des Rohres erhöht ist. Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.The invention aims to remedy this situation. The invention has for its object to provide a device for holding and sealing a pipe in a fitting connection or fitting in which the risk of folding the spring segments is reduced and at the same time the resistance to pulling out of the tube is increased. According to the invention, this object is solved by the features of
Mit der Erfindung ist eine Vorrichtung zum Halten und Abdichten eines Rohres in einem Armaturenanschluss oder Fitting geschaffen, bei der die Gefahr eines Umklappens der Federsegmente beim Herausziehen des Rohres reduziert ist. Durch das Vorsehen zusätzlicher Krallsegmente an den freien Enden der Federsegmente der Krallscheibe und deren im Verhältnis zur Ausrichtung der Federsegmente anderen Winkel ist bereits eine Verbesserung der Klemmwirkung erzielt. Durch die darüber hinaus vorgesehene Anordnung des Stützrings mit der mit den Krallsegmenten korrespondierenden Anlagefläche ist darüber hinaus gewährleistet, dass ein Umklappen der Federsegmente beim Herausziehen des Rohres verhindert ist, da sich die die Verlängerung der Federsegmente bildenden Krallsegmente an der Anlagefläche des Stützrings abstützen. Die Widerstandskraft gegen ein Herausziehen des Rohres ist damit weiter erhöht.With the invention, a device for holding and sealing a pipe in a fitting connection or fitting is provided in which the risk of a folding of the spring segments when pulling out of the tube is reduced. By providing additional claw segments at the free ends of the spring segments of the claw plate and their other angle relative to the orientation of the spring segments an improvement in the clamping effect is already achieved. Furthermore, the arrangement of the support ring provided with the contact surface corresponding to the claw segments ensures that the spring segments are prevented from flipping when the tube is pulled out, since the claw segments forming the extension of the spring segments are supported on the contact surface of the support ring. The resistance to withdrawal of the tube is thus further increased.
Vorteilhaft ist der Neigungswinkel der Krallsegmente bezogen auf die Längsachse des Rohres geringer als der Neigungswinkel der Federsegmente. Dadurch bedingt liegen die Krallsegmente in montiertem Zustand unter einem steileren Winkel an dem Rohr an, wodurch die Krallwirkung erhöht ist.Advantageously, the angle of inclination of the claw segments with respect to the longitudinal axis of the tube is less than the angle of inclination of the spring segments. As a result, the Krall segments are in the assembled state at a steeper angle to the pipe, whereby the Krallwirkung is increased.
In Ausgestaltung der Erfindung bildet die Anlagefläche einen Konus aus. Der Konus ermöglicht eine flächige Anlage auf den Krallsegmenten, so dass die nach dem Aufschrauben der Mutter auf den Gewindestutzen durch den Stützring auf die Krallsegmente ausgeübte Kraft gleichmäßig auf diese verteilt ist, wodurch eine Beschädigung der Krallsegmente selbst bei sehr hohen aufgebrachten Schraubkräften vermieden ist.In an embodiment of the invention, the contact surface forms a cone. The cone allows a flat contact with the claw segments, so that the force exerted after screwing the nut on the threaded connector through the support ring on the Krallsegmente force is evenly distributed on this, thereby damaging the claw segments is avoided even at very high applied screwing.
Die flächige Ausübung der Kraft ist zudem dadurch verbessert, dass in Montageposition der Konuswinkel der Anlagefläche im Wesentlichen dem Winkel der Krallsegmente entspricht.The two-dimensional exercise of the force is also improved by the fact that in the mounting position of the cone angle of the contact surface substantially corresponds to the angle of the claw segments.
Bevorzugt ist der Stützring einteiliger Bestandteil der Mutter. Diese Ausgestaltung führt zu einer unverlierbaren Anordnung des Stützrings, so dass die Montage erleichtert ist. Zudem kann auf die gesonderte Herstellung des Stützrings verzichtet werden, wodurch der fertigungstechnische Aufwand reduziert ist.Preferably, the support ring is an integral part of the mother. This configuration leads to a captive arrangement of the support ring, so that the assembly is facilitated. In addition, can be dispensed with the separate production of the support ring, whereby the manufacturing cost is reduced.
In anderer Ausgestaltung der Erfindung ist der Stützring als separates Bauteil ausgebildet. Zwar erhöht sich hierdurch der fertigungstechnische Aufwand; es besteht jedoch durch diese Ausgestaltung die Möglichkeit, den Stützring an verschiedene Einsatzmöglichkeiten anzupassen, wodurch die Flexibilität der erfindungsgemäßen Vorrichtung sowie deren Anpassung an unterschiedliche Rahmenbedingungen verbessert ist.In another embodiment of the invention, the support ring is formed as a separate component. Although this increases the production engineering effort; However, there is the possibility of adapting the support ring to different applications by this design, whereby the flexibility of the device according to the invention and their adaptation to different conditions is improved.
