Abstract

The join comprises a nut (3) which is screwed onto a collared expander sleeve (1) forming a join proof against force and pressure as well as allowing assembly from one side only. Depending on the sleeve design, the nut can be screwed to this inside or outside so the second size of the nut supports the sleeve, using a connecting thread (6) or other connection designs. The blind screw join is made of plastics, metals or other suitable materials and the nut collar (4) accepts conventional seals (5) which are let into the collar at high pressure to afford seal support from the sides. The sleeve is held in place by two or more outwards-adjustable back-holders to fit into the expander slots. In service, a hole is drilled to suit the sleeve and the nut screwed down onto the sleeve so as to spread the sleeve without obscuring its slots.

Description

Die Erfindung betrifft Blindverschraubungen, bestehend aus einer geschlitzten Spreizhülse und einer Mutter.The invention relates to blind fittings consisting of a slotted expansion sleeve and a nut.

Es gibt eine Vielzahl von Verschraubungen und Befestigungen. Manche dieser Verbindungen sind schwierig, wenn das Gegenstück in einem nicht zugänglichen Behälter liegt oder die Zugangsöffnung des Behälters das Überschreiten einer bestimmten Größe nicht erlaubt. Bei den Blindnietmuttern z. B. ist die Größe derselben durch die immer größer werdenden Verformungskräfte begrenzt, wobei eine absolute Abdichtung nicht gewährleistet ist. Es sind in bestimmten Fällen aufwendige Lösungen erforderlich.There are a variety of fittings and fastenings. Some of these connections are difficult when the counterpart is in an inaccessible container or Access opening of the container exceeding a certain one Size not allowed. With the blind rivet nuts z. B. is the size of the same due to the increasing deformation forces limited, but not an absolute seal is guaranteed. In certain cases, they are complex Solutions needed.

Der Erfindung liegt daher die Aufgabe zugrunde, Kosten und Zeit zu sparen sowie schwierige Verbindungen einfach herzustellen.The invention is therefore based on the object, costs and Save time and make difficult connections easily.

Diese Probleme werden gelöst mit den in den Schutzansprüchen aufgeführten Merkmalen.These problems are solved with those in the protection claims characteristics listed.

Mit der Erfindung lassen sich schnelle, kostengünstige, kraft- und druckschlüssige Verbindungen herstellen, besonders an dünnen Wänden, die an manchen Stellen nicht möglich sind oder nur mit hohen Kosten realisierbar sind.With the invention, fast, inexpensive, Establish non-positive and pressure connections, especially on thin walls, which in some places is not possible are or can only be realized at high costs.

AusführungsbeispielEmbodiment

An die vorgesehene Stelle wird ein Loch mit dem Außendurchmesser der Spreizhülse 1 gebohrt. Die Mutter 3 wird nun soweit auf die Spreizhülse 1 geschraubt, daß die Schlitze der Spreizhülse noch frei sind und die Spreizhülse elastisch verformbar ist. Die Verschraubung wird nun eingedrückt oder eingeschlagen, wobei die Spreizhülse durch die Form des Kragens 2 verengt die Bohrung durchstößt (Fig. 1). Sie wird bis zum Kragen 2 wieder herausgezogen, mit dem Montagewerkzeug 7 fixiert und verschraubt (Fig. 2).A hole with the outer diameter of the expansion sleeve 1 is drilled at the intended location. The nut 3 is now screwed onto the expansion sleeve 1 so far that the slots of the expansion sleeve are still free and the expansion sleeve is elastically deformable. The screw connection is now pressed in or driven in, the expansion sleeve being narrowed through the shape of the collar 2 penetrating the bore ( FIG. 1). It is pulled out again to the collar 2 , fixed with the assembly tool 7 and screwed ( Fig. 2).
