Description
Kupplung für die Verbindung der Zuleitung einesCoupling for connecting the supply line to a
Antriebs- und Kühlmediums, insbesondere in der Déntaltechnik Die Erfindung hetrifft eine Kupplung für die Verbindung der Zuleitung eines Arbeitsmediums mit dem Arbeitswerkzeug der Dentaltechnik, insbesondere für die Vertindure des Zuleitungsschlauches und der Turbine einer Zahnbehrmaschine.Drive and cooling medium, especially in the Déntal technology the The invention concerns a coupling for connecting the supply line of a working medium with the working tool of dental technology, in particular for the vertindure of the supply hose and the turbine of a tooth brush.
Risher erf@lgt die Verbindung des Arbeitswerkzeuges mit der Zuleitung für das Antriehsmedium, indem die Zuleitung des Arbeitsmediums an das Arbeitswerkzeug fast und untrannhar durch eine Randage oder zerlegbar mittels einer festen äberwurfmutter angeschlessen ist. Im ersten Ralle kann die Verbindung ohne Reschädigung den Anschlusses nicht gelöst werden. Im zweiten Falle ist die Trennung zeitraubend und verursacht bei der Verbindung mit der Überwurfmutter eine Reschädigung der Berübrungsflächen. Rei einer festen Verbindung der Zuleitung des Antriebsmediums mit dem Arbeitswerkzeug wird auf das Arbeitswerkzeug eine Kraft übertragen, die durch die Torsion der Zuleitung beim Drehen des Arbeitsworkzeuges hervorgerufen wird.Risher establishes the connection of the working tool with the supply line for the drive medium by the supply line of the working medium to the working tool almost and untrannhar thanks to an edge or can be dismantled by means of a fixed union nut is connected. In the first case, the connection can be made without damaging the connection cannot be resolved. In the second case, the separation is time consuming and deliberate When connecting with the union nut, damage to the contact surfaces. A firm connection between the supply line for the drive medium and the working tool a force is transmitted to the working tool, which is caused by the torsion of the supply line is caused when rotating the work tool.
Die angeführten @achteile werden durch die gemäß der Frfindung vergeschlagene Kupplung heseitigt. Das Wesen dieser Kupplung besteht darin, daß sie aus einem Außenkörper besteht, in den ein Innenkörper dicht hineinragt.The listed disadvantages are suggested by the Clutch removed. The essence of this coupling is that it consists of an outer body consists, into which an inner body protrudes tightly.
Dieser weist in Richtung zu seinem inneren Ende einen allmählich sich verkleinernden Durchmesser auf und hat Einstiche für Dichtungsringe und eine Nut für einen federnden Sichemungsring, der in einem inneren Einstich den zylinderförmigen Ar@enkärpers gelagert ist.This gradually points towards its inner end reducing diameter and has grooves for sealing rings and a groove for a resilient locking ring, which in an inner recess the cylindrical Ar @ enkärpers is stored.
Durch Anwendung der drehbaren Schnellkupplung in der Dentaltechnik, insbesondere bei der Verhindung des Zuleitungssahlauches mit dem Turbinenkörper, wird eine Verbindung und Lösung des Turbinenansatzes mit dem Zuleitungsschlauch ermöglicht. Dies erleichtert dem behandelnden Art den Austausch der Turbinenansätzt je nach den ausgeführten Leistungen und eine Sterilisation, ohne daß die Berührungsverbindungs flächen beschädigt werden.By using the rotatable quick coupling in dental technology, especially when connecting the supply hose to the turbine body, is a connection and solution of the turbine attachment with the supply hose enables. This makes it easier for the treating species to replace the turbine attachments depending on the services performed and a sterilization without affecting the contact connection surfaces are damaged.
Die vorgeschlagene Kupplung ermoglicht, eine rasche Verhindung und Lösung der Zuleitung des Antriehsmediums mit dem Arbeitswerkzeug durch blessen Druck oder Zug.The proposed coupling allows rapid prevention and Solution of the supply of the drive medium with the working tool by applying pressure or train.
Die Kupplung ist fir eine leichte Drehiinp gebaut, so daß die Verbindung die Tersionskräfte nicht überträgt, die bei der ilblichen Ausführung durch Drehung des Arbeitswerkzeuges und die Verdrehung der Zuleitung des Antriebsmediums entstehen würden.The coupling is built for a slight twist, so that the connection the torsional forces are not transmitted, which in the usual execution by rotation of the working tool and the twisting of the supply line of the drive medium develop would.
In der beiliegenden Zeichnung ist als Ausf2hrungsbeispiel eine drehbare Kunplunz: filr die Verbindung der Zuleitung des Arbeits- und Kühlmediums, mit darin Turbinenansatz im Schnitt durch die Längsachse des Turbinenansatzes dargestellt.In the accompanying drawing, a rotatable one is shown as an exemplary embodiment Kunplunz: for the connection of the supply line of the working and cooling medium, with it Turbine attachment shown in section through the longitudinal axis of the turbine attachment.
Der Turbinenansatz ist in dem Teil, der dem Anschluß an den Zuleitungsschlauch dient, mit einem Außenkörper 1 versehen, in dem Rohrungen für die Zufuhr des Antriebsmediums, d.i. von Luft und Kühlmedium, ausgeführt sind.The turbine attachment is in the part that connects to the supply hose serves, provided with an outer body 1, in the pipes for the supply of the drive medium, i.e. of air and cooling medium.
Ferner weist der Außenkörper 1 eine Tnnenringnut für die Lagerung eines federnden Sicherungsringes 2 auf. Der Zuleitungsschlauch des Antriebsmediums hat, einen Innenkörper 3. In diesem sind Bohrungen filr die Zufuhr von Druckluft und Kühlmedium auszeführt. Der innenkörper 3 hat in Richtung zu seinem Ende, das in den Außenkörper 1 dicht hineinragt, einen sich allmählich stufenweise verkleinernden Durchmesser. An der Umfangsfläche weist der Innenkörper 3 Finstiche auf, die der Lagerung von z.B. als O-Ringen ausgebildeten Dichtungsringen Lt dienen. Außerdem hat der Innenkörper 3 eine Nut für den federnden Sieberungaring 2.Furthermore, the outer body 1 has a Tnnenringnut for storage a resilient locking ring 2. The supply hose of the drive medium has an inner body 3. In this are holes for the supply of compressed air and coolant discharges. The inner body 3 has towards its end that protrudes tightly into the outer body 1, gradually decreasing in size Diameter. On the circumferential surface of the inner body has 3 fin stitches that the Storage of sealing rings Lt designed as O-rings, for example. aside from that the inner body 3 has a groove for the resilient sieve ring 2.
Die Arbeitsweise der Kupplung ist folgende: In den Außenkörper 1 im Turbinenansatz wird der Innenkörper 3 hineingeschoben, der das Endstck des Zuleitungsschlauches bildet. Der Innenkörper 3 ist mit Dichtungsringen Lt für die Abdichtung der Antriebsluft des Turbinenansatzes und des Kühlmediums versehen. Beim Einschieben des Innenkörpers 3 in den Außenkörper 1 rastet der Sicherungsring 2 in die Nut im Innenkörper 3 ein. Durch das Einrasten des Sicherungsringes 2 in die Nut des Innenkörpers 3 ist der Zuleitungsschlauch vor dem Rerausfallen oder dem Herausdrticken durch das Druckmedium gesichert. Durch das Einschieben des Innenkörpers 3 in den Außenkörper 1 ist der Turbinenansatz mit der Zuleitung des Antriebs- und Kühlmediums verbunden. Kräfte, die durch Drehung des Turbinenansatzes bei einer starren Verbindung mit der Zufuhrleitung entstehen würden, werden durch die Drehung des Innenkörpers 3 im Außenkörper 1 eliminiert. Die Dichtungsringe Lt trennen bzw. dichten die Verbindungsräume der Druckluft und des Kühlmediums ab, verhindern jedoch nicht ihre gegenseitige Drehung.The mode of operation of the coupling is as follows: In the outer body 1 in the The inner body 3, which is the end piece of the supply hose, is pushed into the turbine attachment forms. The inner body 3 is provided with sealing rings Lt for sealing off the drive air the turbine attachment and the cooling medium. When inserting the inner body 3 in the outer body 1, the locking ring 2 engages in the groove in the inner body 3. By engaging the locking ring 2 in the groove of the inner body 3 is the Supply hose before falling out or being pushed out by the pressure medium secured. By inserting the inner body 3 into the outer body 1, the Turbine attachment connected to the feed line for the drive and cooling medium. Forces, by rotating the turbine attachment with a rigid connection to the supply line would arise are eliminated by the rotation of the inner body 3 in the outer body 1. The sealing rings Lt separate or seal the connecting spaces of the compressed air and of the cooling medium, but do not prevent their mutual rotation.
