Description

Es sind bereits Rohrschlüssel bekannt, deren Spannbacken. das einzuspannende Rohr nahezu vollständig umfassen. Um diese Rohrschlüssel für verschiedene Rohrdurchmesser verwenden, zu können, werden wahlweise Backeneinsätze in die Spannbacken eingesetzt. Die Spannbacken sind an einem Griffhebel abklapphar gelagert und werden an ihren freien Enden durch besondere Haltestifte oder Halteklammern, zusammengehalten. Das Spannen erfolgt mit Hilfe des ,einzigen Grithiebels, an dem die beiden Spannbacken sowohl abklappbar als auch schwenkbar gelagert sind.Pipe wrenches are already known whose clamping jaws. the one to be clamped Cover the pipe almost completely. To order these pipe wrenches for different pipe diameters To be able to use, jaw inserts are optionally inserted into the clamping jaws. The jaws are hinged on a handle lever and are attached to their free ends held together by special retaining pins or retaining clips. That Clamping takes place with the help of the single grill handle on which the two clamping jaws are both foldable and pivotable.

Um ein besonders kräftiges Spannen zu erreichen, wird erfindungsgemäß an einem Spannbacken ein zusätzlicher Griffhebel starr befestigt. Diese Anordnung ermöglicht ein zangenartiges Spannen.In order to achieve particularly strong tensioning, according to the invention an additional handle lever is rigidly attached to a clamping jaw. This arrangement enables pliers-like clamping.

In der Zeichnung ist perspektivisch- der Rohrschlüssel sowohl in geschlossener als auch in offener Form mit seü,nen konstruktiven Einzelheiten dargestellt.In the drawing is perspective - the pipe wrench both in closed as well as in an open form with nice structural details.

Der Spannbacken i trägt in starrer Verbindung den erfindungsgemäßen Griffhebel 2, während der Griffhebel 3 schwenkbar gelagert ist. Mit Hilfeeines Ansatzstiftes 4 ist der zweite Spannbacken 5 .a;n dem Griffhebel 3 schwenkbar gelagert. Um Rohre verschiedenen Durchmessers spannen zu können, können verschieden große Backeneinsätze 6vder 7, die Führungsansätze 8 tragen, in Führungsnuten 9 des Spannbackens 5 reingelegt werden. Die beiden freien Enden der klappbaren Spannbacken tragen Bohrungen und sind durch einen Sicherungsstift io miteinander koppelbar. Der Sicherungsstift io weist einen Schlitz i i auf, in den ein Sicherungsbügel 12 paßt, der die Einsatzbacken in Spannbacken 5 gegen Herausfallen sichert.The clamping jaw i is rigidly connected to the one according to the invention Handle lever 2, while the handle lever 3 is pivotably mounted. With the help of a pin 4, the second clamping jaw 5 .a; n is pivotably mounted in the handle lever 3. To pipes To be able to clamp different diameters, jaw inserts of different sizes can be used 6vder 7, which carry guide lugs 8, placed in guide grooves 9 of the clamping jaw 5 will. The two free ends of the hinged clamping jaws have holes and can be coupled to one another by means of a locking pin. The locking pin io has a slot i i into which a securing bracket 12 fits the insert jaws Secures in clamping jaws 5 against falling out.

Soll ein Rohr gespannt werden, so wird in den abgeklappten Spannbacken 5 zunächst der entsprechende Backeneinsatz 6 oder 7 mit seinem Führungsansatz 8 in :die Führungsnut 9 einsgelegt. Der geöffnete Schlüssel wird über das Rohr geführt, und die beiden Spannbacken werden dann durch den Sicherungsstift io an ihren freien Enden miteinander gekuppelt. Der umgelegte Sicherungsbügel i z sichert dann den. Backeneinsatz gegen Herausfallen. Durch .das nunmehr zangenartige Spannen der beiden Griffschenkel wird das Rohr sicher gehalten.If a pipe is to be clamped, the folded down clamping jaws are used 5 first of all the corresponding jaw insert 6 or 7 with its guide attachment 8 in: the guide groove 9 is inserted. The opened key is passed over the pipe, and the two clamping jaws are then by the locking pin io at their free Ends coupled together. The folded safety bracket i z then secures the. Jaw insert against falling out. By .the now pliers-like clamping of the two The pipe is held securely by the handle leg.
