Description
Gegenstand der Erfindung ist eine Schubsicherung für längs bewegliche, gummigedichtete Schraubmuffer. In bekannter Weise befindet sich am Ende des Einsteckrohres ein Vorsprung, der bei normalem Betrieb auftretende Druckkräfte in sich aufnimmt. Die Beweglichkeit der Schubsicherung liegt aber nicht nur in der Längsrichtung, sondern in gewissem Maße ist auch Winkelbeweglichkeit vorhanden. Damit auf alle Fälle Dichtung herrscht,The subject of the invention is a thrust lock for longitudinally movable, rubber-sealed Screw buffer. In a known manner, there is a projection at the end of the insert tube, which is at absorbs pressure forces occurring during normal operation. The mobility of the thrust protection is not only in the longitudinal direction, but to a certain extent there is also angular mobility available. So that there is poetry in any case,
ίο befindet sich erfindungsgemäß am Spitzteil der Gummidichtung eine im wesentlichen zylindrische Nase. Bei angezogener Verbindung wird diese zwischen einer zum Ende des Einsteckrohres hinführenden Schrägfläche und einer annähernd parallelen Schrägfläche der Muffe unter Spreizung aus der Waagerechten eingeklemmt. Es tritt somit über diese'Nase eine zum Vorsprung zusätzlich wirkende Dichtung auf, ohne daß die Längsbeweglichkeit beeinträchtigt wird, und unter Belassung einer prak-ίο is located according to the invention on the pointed part of the Rubber seal a substantially cylindrical nose. When the connection is tightened, it is between one inclined surface leading to the end of the plug-in tube and one approximately parallel one Inclined surface of the socket clamped in from the horizontal while expanding. It thus passes over this nose has a seal that acts in addition to the projection without impairing the longitudinal mobility is, and leaving a practical
ao tisch ausreichenden Winkelbeweglichkeit. Da bei Schraubmuffenrohren erst die Verbindung fertig hergestellt wird, dann die Anwinklung und anschließend die Festlegung der Rohre vorgenommen wird und die Schubkräfte erst später auftreten,ao table sufficient angular mobility. Since with screw socket pipes only the connection is finished is made, then the angling and then the definition of the pipes and the shear forces appear later,
»5 wird die Anwinklung nicht mehr wesentlich verändert. Die beschriebene Schubsicherung nimmt alle durch den Innendruck oder andere Ursachen auftretenden Längskräfte auf. Rohrverbindungen mit Längsbeweglichkeit unter Benutzung von Einklemmung mittels einer Schrägfläche sind zwar bekannt, aber sie bieten keine Sicherung gegen Längskräfte dar, weil ihnen die der vorliegenden Sicherung so eigenartige Einklemmung zwischen annähernd parallelen Flächen unter Spreizung aus der Waagerechten fehlt.»5 the angle is no longer significantly changed. The thrust protection described takes all by the internal pressure or other causes occurring longitudinal forces. Pipe connections with longitudinal mobility using entrapment by means of an inclined surface are known, but they do not offer any protection against longitudinal forces because the jamming between them, so peculiar to the present fuse, approximates parallel surfaces under expansion from the horizontal are missing.
Die Zeichnung gibt zwei Ausführungsbeispiele wieder je vor und nach Auftreten von Druck.The drawing shows two exemplary embodiments again, each before and after the occurrence of pressure.

Das Einsteckrohr b trägt einen Vorsprung e (Abb. ι und 2) bzw. einen aus einer Mulde aufsteigenden Bund. / (Abb. 3 und 4). In beiden Fällen leitet zu e oder / eine schräge Fläche hin. Der Gummiring α ist ähnlich dem Gummiring der unter dem Wortzeichen »Union« bekannten Schraubmuffe ausgebildet, hat aber eine verlängerte, etwa zylindrische Nase d. Gegen diese Nase ei legt sich von außen ein Vorsprung h der Muffe c, der eine etwa parallel zur oben erwähnten Schrägung liegende Innenwand g bildet. Sobald die Leitung unter Druck gesetzt wird (Abb. 2 und 4), beginnt die Schubkraft das Spitzende b aus der Muffe c herauszuziehen. Es schiebt sich dabei die Nase d des Gummiringes auf die Schräge des Vorsprunges e (Abb. ι und 2) oder die Schräge des Bundes f (Abb. 3 und 4) auf und legt sich mit ihrer Außenseite gegen die Innenwandung g der Muffe c unter Pressung., Das verhindert ein weiteres Hinausgleiten des Einsteckrohres aus der Muffe. Gleichzeitig wird eine zusätzliche Abdichtung der Verbindung erzielt, die um so größer ist, je fester die Nase d des Gummiringes α eingeklemmt wird, also je größer die Schubkraft ist, die von der Größe des Druckes und des Rohrdurchmessers abhängt.The insert tube b carries a projection e (Fig. Ι and 2) or a collar rising from a trough. / (Fig. 3 and 4). In both cases, an inclined surface leads to e or /. The rubber ring α is similar to the rubber ring of the screw socket known under the word symbol "Union", but has an elongated, roughly cylindrical nose d. Against this nose egg lies a projection h of the sleeve c from the outside, which forms an inner wall g lying approximately parallel to the above-mentioned incline. As soon as the line is pressurized (Fig. 2 and 4), the pushing force begins to pull the spigot end b out of the socket c. It pushes the nose d of the rubber ring on the slope of the projection e (Fig. Ι and 2) or the slope of the collar f (Fig. 3 and 4) and lies with its outside against the inner wall g of the sleeve c under Pressing., This prevents the plug-in pipe from sliding further out of the socket. At the same time, an additional seal of the connection is achieved, which is greater, the tighter the nose d of the rubber ring α is clamped, so the greater the thrust, which depends on the size of the pressure and the pipe diameter.
