Description

Die Erfindung bezieht sich auf eine Verbesserung von Einnietmuttern, insbesondere für dünne Bleche, mit einer gegebenenfalls mit einer Dichtungseinlagerinne versehenen, verbreiterten Anlage, einem hinter der Anlage sich erstreckenden Hohlschaft und einem auf diesen aufgeschobenen und beim Aufweiten des Schaftes mit eingeklemmten Gegenring.The invention relates to an improvement of rivet nuts, especially for thin sheet metal, with one optionally with a sealing insert channel provided, widened system, a hollow shaft extending behind the system and one that is pushed onto this and is also clamped when the shaft is expanded Counter ring.

Die Erfindung besteht darin, daß sowohl die Anlage als auch der Gegenring eine zum Halteblech planparallele Einspannfläche aufweisen und der innere, gegen den Hohlschaft gerichtete Rand des Gegenringes sich konisch erweitert.The invention consists in that both the system and the counter ring have a clamping surface plane-parallel to the holding plate and the inner one against the edge of the counter ring directed towards the hollow shaft widens conically.

Die planparallele Einspannung verhindert ein Abbiegen des einzuspannenden Blechrandes .und damit ein Einreißen des Bleches. Dies ist für besonders dünne Bleche von Bedeutung. Die konische Erweiterung des inneren Ringrandes sorgt für einen wirksamen Einspanndruck.The plane-parallel clamping prevents bending of the clamped Sheet edge. And thus a tearing of the sheet. This is for particularly thin sheets significant. The conical expansion of the inner ring edge ensures an effective Clamping pressure.

In der 7eichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Abb. i eine mittels Einnietmutter hergestellte Verbindung zwischen einer Anschlußleitung und der Blechwand eines Behälters im Längsschnitt, Abb. 2 die Einnietmutter in Ansicht von unten und Abb. 3 die zur Herstellung einer flüssigkeits- bzw. gasdichten Verbindung erforderlichen Teile untereinander im Längsschnitt.An exemplary embodiment of the invention is shown in the drawing. It shows Fig. I a connection made by means of a rivet nut between a Connection line and the sheet metal wall of a container in longitudinal section, Fig. 2 the rivet nut in view from below and Fig. 3 for the production of a liquid- or gas-tight Connection required parts with each other in longitudinal section.

Die Einnietmutter 5 ist mit Innengewinde 6 zum Einschrauben einer nicht dargestellten AnschluA-leitung und einer breiten Anlage 7 versehen. Der Hohlschaft 8 der Einnietmutter wird in eine öffnung 9 der Blechwand i o eines im übrigen nicht dargestellten Behälters eingesetzt, so daB , die Antage 7 auf dieser eben aufliegt. Hierauf wird ein mit einem konischen Loch i i versehener Gegenring 12 vom selben Durchmesser wie die Anlage auf den Hohlschaft aufgeschoben und dieser mit einem geeigneten Werkzeug in dem konischen Loch aufgeweitet. Dadurch werden die Anlage 7 und der Gegenring 12 zwangsläufig gegetieinandergepreßt, so daß das Blech i o zwischen .diesen beiden Teilen festgeklemmt wird.The rivet nut 5 has an internal thread 6 for screwing in a Connection line (not shown) and a wide system 7 are provided. The hollow shaft 8 of the rivet nut is otherwise not in an opening 9 in the sheet metal wall The container shown is inserted so that the Antage 7 rests flat on it. A counter ring 12 provided with a conical hole i i is then removed from the same Diameter like the system pushed onto the hollow shaft and this with a suitable tool expanded in the conical hole. This will make the plant 7 and the counter ring 12 inevitably pressed together so that the sheet i o is clamped between .these two parts.

Um den Sitz der Einnietmutter an der Blechwand flüssigkeits- oder gasdicht ausbilden zu können, ist in der Anlage 7 eine ringsum laufende Rille 13 vorgesehen, in. welche ein Dichtungsring 14 eingelegt wird. Dieser wird durch das Aufweiten des Hohlschaftes 8 fest in die Rille 13 gepreßt, wodurch ein Hindurchtreten von Flüssigkeit oder Gas zwischen . der Anlage und dem Blech mit Sicherheit vermieden wird.To the seat of the rivet nut on the sheet metal wall liquid or In order to be able to make it gas-tight, there is a groove 13 running all around in the system 7 provided, in. Which a sealing ring 14 is inserted. This is made possible by the Expanding the hollow shaft 8 firmly pressed into the groove 13, whereby a passage of liquid or gas between. the system and the sheet metal certainly avoided will.
