Description
Lösbare Verriegelung von teleskopartig ineinanderschiebbaren Rohrteilen Die Erfindung geht aus von einer lösbaren Verriegelung von teleskopartig ineinanderschiebbaren Rohrteilen, wobei mit einem Rohrteil ein Spreizglied verbunden ist, das mit einem Spreizring aus elastischem Material, z. B. Kunststoff, zusammenwirkt, der einen in axialer Richtung sich erstreckenden Schlitz aufweist, der den Spreizring radial zusammenpreßbar macht zur Erzielung einer elastisch vorgespannten Schiebeführung in dem anderen Rohrteil, mit dem der durch eine Verdrehung des Spreizgliedes radial aufspreizbare Spreizring eine reibschlüssige Verriegelung bewirkt, wobei der Spreizring mit dem Spreizglied radial über radialversetzte Spiralnuten und Spiralnocken verbunden ist und das Spreizglied axiale Anschläge für den Spreizring aufweist.Detachable locking of telescopic tube parts The invention is based on a releasable locking of telescopically telescopic Pipe parts, with a pipe part is connected to an expansion member with a Spreader ring made of elastic material, e.g. B. plastic, cooperates, the one has in the axial direction extending slot, which radially the expansion ring makes compressible to achieve an elastically prestressed sliding guide in the other pipe part, with which the radial by twisting the expansion member The expandable expansion ring causes a frictional locking, the expansion ring connected to the expansion member radially via radially offset spiral grooves and spiral cams is and the expansion member has axial stops for the expansion ring.
Die Aufgabe der Erfindung besteht gegenüber diesem Bekannten darin, Verriegelungen der soeben genannten Art insoweit zu verbessern, daß sie für die Verwendung als Kolben einer Pumpe geeignet sind.The object of the invention is towards this known person is To improve locks of the type just mentioned that they are for the Use as a piston of a pump are suitable.
Zur Lösung dieser Aufgabe ist vorgesehen, daß die Verriegelung als Kolben einer Pumpe verwendet wird, wobei in Längsrichtung der Rohrteile in an sich bekannter Weise zwei Spreizringe vorgesehen sind, deren Schlitze in an sich bekannter Weise radial gegeneinander versetzt sind, wobei ferner das Spreizglied aus Vollmaterial vorgesehen ist.To solve this problem it is provided that the lock as Piston of a pump is used, in the longitudinal direction of the pipe parts in itself In a known manner, two expanding rings are provided, the slots of which are known per se Way are offset radially from one another, with the expansion member also made of solid material is provided.
Durch die Erfindung wird so auf einfache Weise erreicht, daß die Verriegelung als Kolben einer Pumpe verwendbar ist.By the invention it is achieved in a simple manner that the lock can be used as a piston of a pump.
Die Erfindung wird an Hand eines Ausführungsbeispiels in der Zeichnung näher erläutert. Hierbei zeigt F 1 g. 1 einen Schnitt durch die teleskopartig ineinanderschiebbaren Rohre mit der lösbaren Verriegelung und F i g. 2 einen Schnitt durch die Verriegelung.The invention is explained in more detail using an exemplary embodiment in the drawing. Here, F 1 shows g. 1 shows a section through the telescoping tubes with the releasable lock and FIG. 2 shows a section through the lock.
Aus der Zeichnung ist die lösbare Verriegelung von teleskopartig ineinanderschiebbaren Rohren 1, 2 zu erkennen. Hierbei ist mit einem Rohrteil 2 ein Spreizglied 3 verbunden, das mit zwei Spreizringen 4 aus elastischem Material, z. B. Kunststoff, zusammenwirkt. Die Spreizringe 4 weisen einen in axialer Richtung sich erstreckenden Schlitz 5 auf. Dadurch sind die Spreizringe 4 radial zusammenpreßbar, um eine elestisch vorgespannte Schiebeführung in dem anderen Rohrteil 1 zu erreichen, so daß mit diesem Rohrteil 1 durch eine Verdrehung des Spreizgliedes 3 die Spreizringe 4 radial aufspreizbar sind und dadurch eine reibschlüssige Verriegelung bewirkt wird. Die Spreizringe 4 sind mit dem Spreizglied 3 über radial versetzte Spiralnuten 6 und Spiralnocken 7 verbunden. Das Spreizglied 3 weist axiale Anschläge 8, 9 C für die Spreizringe 4 auf. Die lösbare Verriegelung ist als Kolben einer Pumpe vorgesehen, wobei in Längsrichtung der Rohrteile 1, 2 zwei Spreizringe 4 angeordnet sind, deren Schlitze 5 radial gegeneinander versetzt sind. Das Spreizglied 3 ist aus massivem Material gebildet.The releasable locking of telescopically telescoping tubes 1, 2 can be seen from the drawing. Here, an expanding member 3 is connected to a pipe part 2, which is connected to two expanding rings 4 made of elastic material, for. B. plastic interacts. The expansion rings 4 have a slot 5 extending in the axial direction. As a result, the expansion rings 4 can be radially compressed in order to achieve an elastically prestressed sliding guide in the other pipe part 1 , so that with this pipe part 1 the expansion rings 4 can be radially expanded by rotating the expansion member 3, thereby causing a frictional locking. The expansion rings 4 are connected to the expansion member 3 via radially offset spiral grooves 6 and spiral cams 7 . The expansion member 3 has axial stops 8, 9 C for the expansion rings 4. The releasable lock is provided as a piston of a pump, two expanding rings 4 being arranged in the longitudinal direction of the pipe parts 1, 2, the slots 5 of which are radially offset from one another. The expansion member 3 is made of solid material.
In F i g. 1 ist im übrigen ein Rohr dargestellt, in dem zwei Verriegelungen hintereinanderliegend angeordnet sind. Den beiden, jeweils als Kolben einer Pumpe dienenden Verriegelungen ist schließlich ein Ventilkörper 10 vorgeordnet, während bei 11 ein Betätigungshandgriff angedeutet ist.In Fig. 1 shows a tube in which two locks are arranged one behind the other. Finally, a valve body 10 is arranged upstream of the two locks, each serving as a piston of a pump, while at 11 an actuating handle is indicated.
