Abstract

The tool is a development of Patent Application P 3504843.3. The development consists in insert jaws of various sizes being provided which can be inserted into the hexagon of the tool so that one tool can be used for screwed connections of various size. The jaws of the tool can be opened and closed by means of stoppers. The insert jaws have safety devices to prevent slipping. The mandrel is fastened in a laterally pivotable manner inside a jaw of the tool by means of a bolt. One and the same tool can thus be used for at least three sizes of screwed connections.

Description

Die Erfindung betrifft eine Weiterentwicklung des der Patentanmeldung Akz. P 35 04 843.3 zugrundeliegenden Erfindungsgedankens.The invention relates to a further development of the Patent application Akz. P 35 04 843.3 underlying Invention idea.

Bei dieser Anmeldung ist für jede Verschraubungsgröße ein komplettes Gerät erforderlich. Dies ist teuer in der Herstellung und erfordert größere Lagerhaltung. Auch für den Monteur ist es umständlich, eine Anzahl solcher Geräte mitzuführen, für jede Verschraubungs­ größe.This registration is for every screw size a complete device is required. This is expensive in the manufacture and requires larger warehousing. It is also cumbersome for the fitter, a number to carry such devices for every screw connection size.

Die Erfindung sieht nun vor, daß in das Normalgerät Einsätze verschiedener Rohrverschraubungsgrößen ein­ gesetzt werden können, z. B. ein Gerät mit drei verschie­ dengroßen Einsätzen. Es genügen so für alle vorkommenden Rohrverschraubungen zwei bis drei Geräte. The invention now provides that in the normal device Inserts of different pipe fitting sizes can be set, e.g. B. a device with three different the big missions. It is enough for everyone Pipe fittings two to three devices.  

Eine weitere Verbesserung besteht darin, daß der Schlag­ dorn in einem Gelenk innerhalb eines Backens schwenk­ bar ist, so daß man die Möglichkeit hat, bei nebenein­ ander verlaufenden Rohren, die Richtung des Dorns bei der Bewegung der Verschraubung, zwischen den Rohren einzu­ stellen, was die Arbeit erleichtert.Another improvement is that the blow swivel mandrel in a joint within a jaw is cash, so that you have the opportunity to be next door other pipes, the direction of the mandrel at the Movement of the fitting to insert between the pipes what makes the job easier.

Schließlich ist zum Öffnen der Backen ein herausnehm­ barer Stöpsel vorgesehen.Finally there is a take out to open the jaws plugs provided.

Die Zeichnung veranschaulicht das Gerät in beispiels­ weiser Ausführung. Es zeigtThe drawing illustrates the device in example wise execution. It shows

Fig. 1 eine Draufsicht auf das Gerät in geschlossenem Zustand, Fig. 1 is a plan view of the apparatus in the closed state,

Fig. 2 eine dito, in geöffnetem Zustand. Fig. 2 is a ditto, in the open state.

Das Gerät besteht aus zwei halben Backen 1, die im Dreh­ punkt 3 schwenkbar, und an der gegenüberliegenden Seite mit einem Stöpsel 4 verbindbar sind. Eine Backe 1 hat einen Dorn 5, der mittels eines Bolzens 6 im Backen gelenkig befestigt ist. In dem eigentlichen Sechskant 2 des Gerätes ist ein Sechskanteinsatz 7 vorgesehen, der ebenfalls aus zwei Hälften besteht. Es können verschie­ dene solcher Backen mit verschiedengroßem Seckskant eingesetzt werden, die es ermöglichen, ein und dasselbe Gerät für verschiedene Verschraubungsgrößen zu benutzen. Die Backen 1 haben am Drehpunkt 3 Verzinkungen 8, 9 und beim Verbindungsstöpsel 4 Verzinkungen 10, 11. Die Einsatzbacken 7 haben an einer Seite eine über das Sechskant hinaus vorspringende dünne Auflagefläche 12. An der Gegenseite kann ein Magnet oder eine Blattfeder angebracht sein, um ein Verrutschen des Backens 7 zu verhindern.The device consists of two half jaws 1 , which can be pivoted at the pivot point 3 and can be connected to a stopper 4 on the opposite side. A jaw 1 has a mandrel 5 which is articulated in the jaw by means of a bolt 6 . In the actual hexagon 2 of the device, a hexagon insert 7 is provided, which also consists of two halves. It can be used various such jaws with different sized hexagon, which make it possible to use one and the same device for different screw sizes. The jaws 1 have 3 galvanizations 8, 9 at the pivot point and 4 galvanizations 10, 11 at the connecting plug. The insert jaws 7 have on one side a thin contact surface 12 projecting beyond the hexagon. A magnet or a leaf spring can be attached to the opposite side in order to prevent the jaw 7 from slipping.

Durch Herausnahme des Stöpsels 4 können die Backen 1 geöffnet werden, was auch für die Einsatzbacken 7 gilt. Das Gerät läßt sich mit oder ohne Einsatzbacken bequem handhaben. Bei der Drehbewegung des Gerätes während dem Lösen einer Verschraubung, läßt sich der Dorn 5 durch entsprechendes Schwenken in die gewünschte Richtung (Rohrleitung) bringen.By removing the plug 4 , the jaws 1 can be opened, which also applies to the insert jaws 7 . The device can be handled comfortably with or without insert jaws. When the device rotates while loosening a screw connection, the mandrel 5 can be brought into the desired direction (pipeline) by swiveling accordingly.
