Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine Druckschlauchklemme zum Verbinden von Rohren mit elastischen Schläuchen, insbesondere Schläuchen mit ungleichmäßiger Wandstärke, bei der das Anpressen des elastischen Sehlauchendes gegen das in dieses eingeschobene zylindrische Rohrende, durch einen elastischen Klemmkörper erfolgt, welcher durch axiales Verschieben einer innenkegligen Hülse in seinem Durchmesser verkleinert und vergrößert werden kann.The invention relates to a pressure hose clamp for connecting pipes with elastic hoses, in particular hoses with uneven wall thickness, in which the pressing of the elastic The end of the tube against the cylindrical tube end pushed into it, by means of an elastic clamping body takes place, which is reduced in diameter by axially moving an internally conical sleeve and can be enlarged.
Die bisher bekannten Druckschlauchklemmen dieser Art sind ausnahmslos aus metallischen Werkstoffen hergestellt. Ihre einzelnen Elemente gestatten zwar eine Verschiebung zueinander in axialer Richtung, soweit dies für das Funktionieren der Druckschlauchkiemme erforderlich ist. In Richtung quer zu ihrer Längsachse sind sie jedoch infolge der Starrheit des Metalls starr, d. h. in allen ihren Querschnitten zentrisch zur Längsachse- der Druckschlauchklemme gebunden. Diese zentrische Gebundenheit der Elemente der Druckschlauchklemme hat erhebliche Nachteile zur Folge:The previously known pressure hose clamps of this type are without exception made of metallic materials manufactured. Although their individual elements allow a displacement to one another in the axial direction, as far as this is necessary for the functioning of the pressure hose connector. In the direction across hers However, due to the rigidity of the metal, they are rigid in the longitudinal axis; H. centric in all of its cross-sections bound to the longitudinal axis of the pressure hose clamp. This centric bondage of the elements the pressure hose clamp has significant disadvantages:
.1. Ungleiche Pressung bei ungleichen Schlauchwandstärken infolge. der üblichen Herstellungstoleranzen. .1. Uneven pressure with unequal hose wall thicknesses as a result. the usual manufacturing tolerances.
Fig.-3 zeigt einen exzentrischen Schlauch: Innen- und Außenkreis haben: nicht den gleichen Mittelpunkt;Fig. 3 shows an eccentric hose: inner and outer circles have : not the same center;
Fig. 4 zeigt einen unrunden Schlauch: Innenbegrenzung der Schlauchwand ist kreisförmig; äußere Begrenzung ist eine geschlossene, nicht kreisförmige Linie. - -4 shows a tube that is not round: the inner boundary of the tube wall is circular; outer limit is a closed, non-circular line. - -
Fig. 5 zeigt einen upTunden Schlauch, bedingt durch Aufbau der Schlauch wandung: Das Gewebe ist zweifach gewickelt und überlappt an der Stoßstelle. - .Fig. 5 shows an hour tube, caused by the structure of the tube wall: the fabric is twofold wrapped and overlapped at the joint. -.
Ein Beispiel- der Wirkung derartiger Schläuche in y Verbindung mit Schlauchklemmen bisheriger Bauart ist in Fig. 1 dargestellt. Die durch Gewinde 1 zurOne of example of the effect of such hoses in the y connection with hose clamps of previous design is shown in FIG. 1. The thread 1 to
Längsachse des starren Nippels 2 zentrisch gebundene Longitudinal axis of the rigid nipple 2 centrally bound
innenkeglige Schraubhülse 3 drückt den -elastisch^ju ι Klemmkörper 4 zentrisch gebunden gegen- Wider-— lager 5 und die stärkere Zone 6 des Schlauches 7, wobei die schwächere Zone 8 des Schlauches 7 nicht mehr durch Klemmkörper 4 gegen den starren Nippel 2 gepreßt werden kann, weil das Anliegen des Klemmkörpers an der stärkeren Zone 6 ein Weiterbewegen der starren innenkegligen Hülse 3 über Gewinde 1 nach links unmöglich macht. Eine solche Verbindung ist undicht.inner conical screw sleeve 3 presses the -elastisch ^ ju ι clamp body 4 centrally bound against-abutment 5 and the stronger zone 6 of the hose 7, the weaker zone 8 of the hose 7 no longer being pressed against the rigid nipple 2 by the clamp body 4 can, because the contact of the clamping body on the stronger zone 6 makes it impossible to move the rigid inner conical sleeve 3 via thread 1 to the left. Such a connection is leaky.
2. Wird die aus metallischem Werkstoff hergestellte Druckschlauchklemme durch unsachgemäße Behandlung, wie es im rauhen Betrieb leicht vorkommt, infolge Schlages oder Stoßes in ihren Anpreßsteilen (keglige Schraubhülse, starrer Nippel) zentrisch verformt, so dichtet sie mangels zentrischer Klemmkörperführung als Folge der bleiben-2. If the pressure hose clamp made of metallic material is improperly handled, as it easily happens in rough operation, as a result of blows or bumps in their pressing parts (conical screw sleeve, rigid nipple) centrally deformed, so it seals more centrically for lack of it Sprag guidance as a result of the remaining

den Verformung nicht mehr. Die Druckschlauchklemme ist damit wertlos.the deformation no longer. The pressure hose clamp is worthless.
3. Für diesen Zweck preislich vertretbare metallische Werkstoffe sind nur mehr oder weniger korrosionsfest. 3. Metallic materials that are reasonably priced for this purpose are only more or less resistant to corrosion.
4. Der verhältnismäßig hohe Reibungswert von Metall auf Metall (dies besonders, wenn die Korrosion bereits eingesetzt hat) verlangt zum Anziehen der Druckschlauchklemme den Aufwand einer erheblichen Kraft und die Anwendung besonderer Werkzeuge. ·4. The relatively high coefficient of friction between metal and metal (especially when there is corrosion has already used) requires the effort of tightening the pressure hose clamp considerable strength and the use of special tools. ·
5. Der Reibungswert zwischen gleitendem Klemmkörper und Innenkonus ist erheblich. Die zu ihrer Überwindung anzusetzende Kraft geht auf Kosten des Anpreß druckes von dem Schlauch -auf den Nippel verloren.5. The coefficient of friction between the sliding clamp body and the inner cone is considerable. To hers Overcoming the force to be applied is at the expense of the contact pressure from the hose -to the Lost nipples.
6. Die Gewinde von metallischen Verbindern bedürfen «iner dauernden Schmierung, also eines zu-- sätzlichen Material- und Arbeitsaufwandes.6. The threads of metallic connectors require permanent lubrication, i.e. one that additional material and labor.
7. Die Fabrikation der ,Druckschlauchklemme in Metall ist herstellungsmäßig kostspielig. Ihre einzelnen ^Peile müssen zu Rohlingen gegossen und dann zum- Herstellung von Innenkonus bzw. Klemmring und'Gewinde spangebend bearbeitet werden.7. The manufacture of the pressure hose clamp in metal is expensive to manufacture. Your individual ^ bearings must be cast into blanks and then machined to produce the inner cone or clamping ring and thread.
Durch die Erfindung ist die Aufgabe gelöst, insbesondere den unter Punkt 1 beschriebenen Mangel zu beheben, d. h. eine Schlauchklemme der in Rede stehenden Art zu konstruieren, die funktionell das Bedürfnis berücksichtigt, exzentrische und unrunde Schläuche zu verbinden.The invention solves the problem, in particular the deficiency described under point 1 fix, d. H. To construct a hose clamp of the type in question that functionally meets the need takes into account the connection of eccentric and non-circular hoses.
Erfindungsgemäß wird eine Druckschlauchklemme vorgeschlagen, bei der ein, einige oder alle Teile aus einem Kunststoff gefertigt sind, wie er z. B. unter dem Begriff »Polyamide« bekannt ist, oder aus einem Kunststoff mit ähnlichen mechanischen Eigenschaften. Dieser Kunsstoff muß eine solche Härte und Elastizität haben, daß einerseits die aus ihm gefertigten Teile eine genügende Festigkeit zum Einarbeiten tragender Gewinde aufweisen und der es anderseitsAccording to the invention, a pressure hose clamp is proposed in which one, some or all of the parts are made of a plastic, as z. B. is known under the term "polyamides", or from one Plastic with similar mechanical properties. This plastic must have such hardness and elasticity have that, on the one hand, the parts made from it have sufficient strength to incorporate load-bearing Have thread and the other hand
