Description
Endtülle für Stahlpanzerrohre Beim Verlegen von Stahlpanzerrohren muß dafür gesorgt werden, daß sich die Kabel an dien Austrittsstellen nicht verletzen können. Zu diesem Zweck verwendet man I:udtüllen,@ welche bisher durch Verschrauben an den Rohren befestigt wurden. Diese Befestigungsart hat jedoch dien großen Nachteil, daß Gewinde :aufgeschnitten werden muß, !und in den meisten Fällen muß hierzu das- eingesetzte Rohr noch einmal abgenommen werden, um iri den Schraubstock eingespannt zu werden. Als weiterer Nachteil tritt hinzu; daß -der Verbrauch an Schneidwerkzeugen infolge des harten Werkstoffs sehr groß ist.End cap for armored steel pipes When laying armored steel pipes It must be ensured that the cables do not injure themselves at the exit points can. For this purpose one uses I: udtüllen, @ which so far by screwing attached to the pipes. However, this type of fastening has the major disadvantage that thread: has to be cut! and in most cases this has to be done inserted tube can be removed again to clamp the vice to become. Another disadvantage is; that -the consumption of cutting tools is very large due to the hard material.
Für Isolierrohr bei elektrischen Hausanlagen ist es npn bekannt, die Tüllen durch einfachfies Aufstecken zu befestigen. Versuche, diese Befestigungsart auch bei Stahlpanzerrohr anzuwenden, blieben @ergebnislos, @da hier viel höhere Ansprüche an die Festigkeit gestellt werden. Außerdem ist Stahlpanzerrohr wenig elastisch, so. däß infolge der:unvermeid-Iichen Ungenauigkeiten dies Rohres kein richtiger Sitz durch einfaches Aufschieben erzielt werden kann.For insulating tube in electrical house systems, it is known npn that The grommets can be attached by simply pushing them on. Try this type of attachment Also to be used with armored steel pipe, remained @ resultless, @ because here much higher There are demands on the strength. In addition, armored steel pipe is little elastic, like that. that due to the inevitable inaccuracies of this pipe no correct fit can be achieved by simply sliding it on.
Diese Nachteile werden nun nach der Erfindung dadurch beseitigt, daß die aus einem plastischen Material hergestellten Tüllen an den Führungsflächen mit Erhöhungen (Wulsten, Warzen usw.) versehen sind. Die Erhöhungen haben die Aufgabe, die Rohrungenauigkeiten auszugleichen, und gewährleisten durch ihre Verformung beim Einpressen ` einen -einwandfreien Sitz.These disadvantages are now eliminated according to the invention in that with the grommets made of a plastic material on the guide surfaces Elevations (bulges, warts, etc.) are provided. The task of the increases is compensate for the pipe inaccuracies, and guarantee by their deformation during Pressing in a perfect fit.
In der Zeichnung sind einige Ausführungsbeispiele der Erfindung dargestellt. Gemäß Fig. t ist eine Innentülle b in das Rohr a eingepreßt, während gemäß Fig. zeine Außentülle c ;auf das Röhr aufgezogen ist. Die Wulste sind in diesen beiden Figuren in dem verformten Zustand dargestellt, wie er sich durch den Zusammenbau ergibt. In Fig. 3 ist eine Endtülle mit einem Wulst d gezeichriet, welche durch Drehen auf Automaten hergestellt werden kann. Fig. q. zeigt eine Ausführung mit zwei Beingewalzten Wulsten e. In Fig. 5 ist eine Tülle dargestellt, bei .der die Erhöhungen in Form von Warzen/ vorgesehen sind.Some exemplary embodiments of the invention are shown in the drawing. According to FIG. T, an inner sleeve b is pressed into the tube a, while according to FIG. z an outer spout c; onto which the tube is pulled. The bulges are in these two Figures shown in the deformed state as he progressed through assembly results. In Fig. 3 an end grommet with a bead d is gezeichriet, which through Turning can be made on automats. Fig. Q. shows a version with two leg rolled beads e. In Fig. 5, a spout is shown in .der the Elevations in the form of warts / are provided.
