Description

Einzieheisen für Stiftschrauben Mit der Anwendung bekannter Einzieheisen ist der Nachteil verbunden, daß mit dem Lösen der Einziehvorrichtung nach dem Festziehen der Stiftschraube häufig eine Lockerung derselben auftritt. Pulling iron for studs With the use of known pulling irons is associated with the disadvantage that with the loosening of the retractor after tightening loosening of the stud often occurs.

Dem Übelstand wird erfindungsgemäß durch ein Einzieheisen abgeholfen, das aus einer Gewindehülse sowie einem dazugehörigen Gewindedorn besteht. Die Gewindehülse ist nach der Neuerung auf ihrer Innenseite mit zwei voneinander unabhängigen Gewinden versehen. Davon dient das eine zum Aufschrauben der Hülse auf der festzuziehenden Stiftschraube ; in das andere gewinde wird der Gewindedorn eingeschraubt, der zum Kontern dient. Dieser Dorn wird zweckmäßig an seinem unteren Ende mit einer kegelförmigen Spitze versehen, um eine punktförmige Auflage am Kopf der Stiftschraube zu erzielen.According to the invention, the inconvenience is remedied by a pulling iron, which consists of a threaded sleeve and an associated threaded mandrel. The threaded sleeve is according to the innovation on its inside with two independent threads Mistake. One of these is used to screw the sleeve onto the one to be tightened Stud screw; The threaded mandrel is screwed into the other thread, which is used for the Countering serves. This mandrel is expediently tapered at its lower end Pointed to achieve a point-like contact with the head of the stud screw.

Ein Ausführungsbeispiel der Neuerung ist in einer Zeichnung dargestellt. Es handelt sich hier um eine Gewindehülse 1, die auf ihrer Innenseite mit zwei Gewinden 2 und 3 versehen' ist. Diese sind durch eine Hinterdrehung 4 voneinander getrennt, damit die Hülse 1 beim Aufziehen auf die nicht dargestellte Stiftschraube nicht zu weit gedreht werden kann.An embodiment of the innovation is shown in a drawing. This is a threaded sleeve 1 that has two threads on its inside 2 and 3 'is provided. These are separated from each other by an undercut 4, so that the sleeve 1 when pulling on the stud screw, not shown, not can be rotated too far.

Am oberen Ende der Gewindehülse 1 ist ein Schlüsselkopf 5 vorgesehen, um ihre Handhabung zu erleichtern. In diesem Sinne ist auch der Gewindedorn 6 an seinem Kopf ausgebildet, der in den oberen Abschnitt der Hülse 1 eingeschraubt ist.At the upper end of the threaded sleeve 1 is a key head 5 intended, to make them easier to use. In this sense, the mandrel 6 is also on formed its head, which is screwed into the upper portion of the sleeve 1.

An seinem unteren Ende weist der Dorn 6 eine Kugel 7 auf, die seine punktförmige Auflage an der Stiftschraube gewährleistet.At its lower end, the mandrel 6 has a ball 7, which his punctiform contact guaranteed on the stud screw.

Wie erwähnt kann aber der Dorn 6 anstelle dieser Kugel auch mit einer kegelförmigen Spitze versehen werden, ohne daß die fortschrittliche Wirkung der Vorrichtung beeinträchtigt wird.As mentioned, however, the mandrel 6 can also have a ball instead of this conical tip without affecting the advanced effect of the Device is impaired.
