Description
Rohrkopplung. Es sind Rohrkupplungen für zwei mitein ander zu verbindende Rohre bekannt gewor den, bei welchen das eine der zu verbindenden Rohrenden mit einer schraubenlinienförmigen Borte versehen ist, während am andern, in dieses erste hineinragenden Rohrende eine Klaue angeordnet ist, welche über diese Borte greift.
Diese Rohrkupplungen haben den Nach teil, dass die Klaue meistens schon nach kürzerem Gebrauch vom Rohr losgerissen wird.
Zweck vorliegender Erfindung ist es, die sen Nachteil zu beheben. Erfindungsgemäss wird dies dadurch erreicht, dass bei einer Rohr kupplung, bei welcher das eine der zu ver bindenden Rohrenden mit mindestens einer schraubenlinienförmigen Borte versehen ist, am andern Rohrende, welches ein konisches Mündungsstück aufweist, hinter diesem Mün dungsstück mindestens eine Lasche angeord net ist, die wenigstens den vierten Teil des Rohrumfanges einnimmt und deren gegen die Mündung zu liegender Saum als schrauben- linienförmige Führung ausgebildet ist, welche dazu bestimmt ist, die schraubenlinienförmige Borte des andern Rohrendes aufzunehmen.
Zwei Ausführungsformen des Erfindungs gegenstandes sind auf der Zeichnung bei spielsweise dargestellt. Es zeigen Fig. 1 eine Ansicht des engeren Rohrendes und eine Draufsicht, Fig. 2 eine Ansicht des weitem Rohrendes und eine Draufsicht, Fig. 3 beide Rohrenden ineinandergesteckt und die zugehörige Draufsicht, und Fig. 4 die Kupplung in einer andern Aus führungsform.
Das weitere Rohrende 1 weist eine schraubenlinienförmig verlaufende Borte 2 auf, welche einem Gewindegang gleichkommt.
Das engere Rohrende 3 mit seinem koni schen Mündungsstück 4 besitzt eine Lasche 5, die wenigstens den vierten Teil des Rohr umfanges einnimmt und deren gegen das Mündungsstück zu liegender Saum eine schraubenlinienförmige Führung 6 bildet. Die Verbindung der beiden Rohrenden erfolgt in an sich bekannter Weise durch Ineinander stecken und Versebrauben der Rohrenden.
Bei dem Ausführungsbeispiel nach Fig. 4 sind die Verschraubungsteile einem doppel gängigen Gewinde entsprechend ausgeführt, wodurch eine noch grössere Dauerhaftigkeit erreicht wird. Zwei schraubenlinienförmige Borten 2 sind am Rande des weiteren Rohr endes 1 einander gegenüberliegend angeord net. Eine entsprechende Anordnung weisen auch die Laschen 5 mit den Führungen 6 am Rohrende 3 auf.
Vorteilhaft wird die Führung 6 an ihrem Anfangsteil mit einer trichterförmigen Er weiterung 7 versehen, wodurch das Ineinander schrauben der Rohrenden erleichtert wird.
Pipe coupling. There are pipe couplings for two mitein other pipes to be connected to the known, in which one of the pipe ends to be connected is provided with a helical border, while on the other, in this first protruding pipe end a claw is arranged, which engages over this border.
These pipe couplings have the disadvantage that the claw is usually torn loose from the pipe after only a short period of use.
The purpose of the present invention is to remedy this disadvantage. According to the invention, this is achieved in that in a pipe coupling in which one of the pipe ends to be connected is provided with at least one helical border, at the other pipe end, which has a conical mouthpiece, at least one tab is arranged behind this mouthpiece, which occupies at least the fourth part of the pipe circumference and whose edge, which is to be located against the mouth, is designed as a helical guide, which is intended to accommodate the helical border of the other pipe end.
Two embodiments of the subject invention are shown in the drawing for example. 1 shows a view of the narrower pipe end and a plan view, FIG. 2 shows a view of the wider pipe end and a plan view, FIG. 3 shows both pipe ends plugged into one another and the associated plan view, and FIG. 4 shows the coupling in another embodiment.
The other pipe end 1 has a helical border 2 which is equivalent to a thread.
The narrower end of the tube 3 with its conical mouth piece 4 has a tab 5 which occupies at least the fourth part of the tube circumference and forms a helical guide 6 against the mouth piece to lie edge. The two pipe ends are connected in a manner known per se by inserting the pipe ends into one another and screwing them together.
In the exemplary embodiment according to FIG. 4, the screw connection parts are designed in accordance with a double thread, whereby an even greater durability is achieved. Two helical braids 2 are on the edge of the other pipe end 1 opposite each other angeord net. The tabs 5 with the guides 6 at the pipe end 3 also have a corresponding arrangement.
The guide 6 is advantageously provided at its initial part with a funnel-shaped extension 7, which makes it easier to screw the pipe ends into one another.
