Abstract

The compressed air coupling with an axially movable locking sleeve (1) and a yoke-form pressure compensating component (2) is guided in a coupling component (3) which on the guiding diameter (14) has a ball locking groove (17) which is increased in the diameter. The coupling component has a seal (13) sliding on the locking sleeve to separate the pressure chamber (6) from the outside air. The coupling component has an external thread and a centering spigot. An independent claim is included for a housing for wall attachment with one or more holes for the mounting of compressed air couplings.

Description

Die Erfindung bezieht sich auf eine Druckluftkupplung mit federbelastetem Ventil und axial verschiebbarer Verriegelungshülse mit einem zapfenförmigen Druckausgleichsteil geführt in einem Kupplungskörper für Festeinbau, der mit einer Zusatzrastung und nach außen wirkender Dichtung versehen ist.The The invention relates to a compressed air coupling with spring-loaded Valve and axially displaceable locking sleeve with a peg-shaped pressure compensation part guided in a coupling body for permanent installation, which is provided with an additional catch and acting outward seal.

Druckluftkupplungen mit federbelastetem Ventil, axial verschiebbarer Verriegelungshülse und verbundenem Druckausgleichsteil geführt in einem Kupplungskörper sind bekannt.Air Couplers with spring-loaded valve, axially displaceable locking sleeve and connected Pressure equalization led part in a coupling body are known.

Die Ausführung mit axial verschiebbarer Veriegelungshülse und zapfenförmigen Druckausgleich gewährleistet einen exakten Ausgleich der an der Verriegelungshülse wirkenden Axialkräfte, sichert jedoch bei Zugkräften am Kupplungsstecker nicht umfassend die Verbindung von Druckluftkupplung und Kupplungsstecker im Arbeitsprozess. Hinzu kommt, daß die bekannten Ausführungen des Druckausgleichsteiles aufwendig sind.The execution ensured with axially displaceable locking sleeve and peg-shaped pressure compensation an exact balance acting on the locking sleeve axial forces, but secures with tensile forces on the coupling plug not comprising the connection of compressed air coupling and coupling plug in the working process. In addition, the known versions the pressure compensation part are expensive.

Der Erfindung liegt die Aufgabe zu Grunde, bei Druckluftkupplungen mit federbelastetem Ventil und axial verschiebbarer Verriegelungshülse mit einem zapfenförmigen Druckausgleich geführt in einem Kupplungskörper für Festeinbau eine zusätzliche Rastung der Kugelverriegelung zwischen Druckluftkupplung und Kupplungsstecker zu deren sicheren Verbindung zu schaffen. Außerdem war eine einfache Lösung der Dichtung der Verriegelungshülse zur Außenluft zu finden.Of the Invention is the object of the invention, with compressed air couplings spring-loaded valve and axially displaceable locking sleeve with a cone-shaped Pressure compensation led in a coupling body for permanent installation an additional Locking of the ball lock between the compressed air coupling and the coupling plug to create their secure connection. In addition, a simple solution was the Seal the locking sleeve for outside air to find.

Erfindungsgemäß geschieht das dadurch, daß in dem Kupplungskörper für Festeinbau eine Kugelrastrille angeordnet wird, in die die Kugeln, nach der Verbindung der Druckluftkupplung mit dem Kupplungsstecker einfallen können und damit eine Rastkraft entsteht, die ein leichtes Ziehen des Kupplungsteckers verhindert.According to the invention happens this by the fact that in the coupling body for permanent installation a ball detent is placed, into which the balls, after the Connect the compressed air coupling with the coupling plug can and thus a latching force is created, which is a slight pulling the coupler plug prevented.

Durch die Anordnung einer Dichtung im Ventilkörper für Festeinbau, die auf der Verriegelungshülse gleitet wird die Trennung zur Außenluft und damit eine einfache Ausführung des Druckausgleichsteiles gewährleistet.By the arrangement of a seal in the valve body for permanent installation, which slides on the locking sleeve becomes the separation to the outside air and thus a simple execution ensures the pressure compensation part.

Im folgenden ist die Erfindung an einem Ausführungsbeispiel dargestellt.in the The following is the invention of an embodiment shown.

Entsprechend Bild 1 wird die axial verschiebbare Verriegelungshülse 1 und das mit ihr verbundene Druckausgleichsteil 2 in dem Kupplungskörper 3 geführt. Das Druckausgleichsteil 2 besitzt die Dichtungen 4 und 5, die den Druckraum 6 zu dem mit der Umgebung verbundenen Raum 7 abdichten. Der Druckraum 6 ist über die Bohrung 8 auch mit dem Innenraum 9 des Kupplungskörpers 3 verbunden. Die Flächen 10 und 11 gewährleisten den axialen Druckausgleich. In der dargestellten Ausgangsstellung ist das für die erfinderische Lösung nicht im Detail wichtige Ventil 12 zur Umgebung geschlossen.According to Figure 1, the axially displaceable locking sleeve 1 and the pressure compensation part connected to it 2 in the coupling body 3 guided. The pressure compensation part 2 owns the seals 4 and 5 that the pressure room 6 to the room connected to the environment 7 caulk. The pressure room 6 is over the hole 8th also with the interior 9 of the coupling body 3 connected. The surfaces 10 and 11 ensure axial pressure compensation. In the initial position shown is not important for the inventive solution in detail valve 12 closed to the environment.

Durch den Dichtring 13 im Kupplungskörper 3, gleitend auf dem Führunsdurchmesser 14 der Verriegelungshülse 1 wird der Druckraum 6 und 9 zur Umgebung abgedichtet. Die in der Verriegelungshülse 1 befindlichen Kugeln 15 werden durch den Kupplungskörper 3 und die Hülse 16 in der dargestellten Lage gehalten. In dem Kupplungskörper 3 ist die im Durchmesser zu Führungsdurchmesser 14 vergrößerte Rastrille 17 angeordnet.Through the sealing ring 13 in the coupling body 3 , sliding on the guide diameter 14 the locking sleeve 1 becomes the pressure room 6 and 9 sealed to the environment. The in the locking sleeve 1 located balls 15 be through the coupling body 3 and the sleeve 16 held in the position shown. In the coupling body 3 is the diameter to guide diameter 14 enlarged latching groove 17 arranged.

Wird gemäß Bild 2 der Kupplungsstecker 18 mit international gebräuchlichem Steckerprofil in die Verriegelungshülse 1 gesteckt, wird die Hülse 16 nach rechts verschoben und die Kugeln 17 können in die Rille 19 des Kupplungssteckers 18 einfallen. Damit gelangt die Verriegelungshülse 1 in die dargestellte rechte Endlage und Druckluftkupplung und Kupplungsstecker sind miteinander verriegelt.If according to picture 2 the coupling plug 18 with internationally used plug profile in the locking sleeve 1 plugged in, the sleeve becomes 16 moved to the right and the balls 17 can get into the groove 19 of the coupling plug 18 come to mind. This will get the locking sleeve 1 in the illustrated right end position and compressed air coupling and coupling plug are locked together.

In der dargestellten Endlage werden die Kugeln 15 durch die Schräge 20 des Kupplungssteckers 18 in die Rastrille 17 gedrückt, wodurch sich eine Rastkraft ergibt, die der Trennung des Kupplungssteckers 18 entgegenwirkt. Über das Gewinde 21 und die Zentrierung 22 wird der Ventilkörper 3 für Festeinbau von dem Gegenstück, z. B. Wanddose oder Verteiler aufgenommmen.In the illustrated end position, the balls 15 through the slope 20 of the coupling plug 18 in the restroom 17 pressed, resulting in a latching force, the separation of the coupling plug 18 counteracts. About the thread 21 and the centering 22 becomes the valve body 3 for permanent installation of the counterpart, z. B. wall socket or distributor aufgenommmen.
