Description

Den Gegenstand der Erfindung bildet eine Sicherungsvorrichtung gegen unerlaubtes Lösen von Schrauben* insbesondere für Waagen,, bei welcher der Schraubenkopf mittels einer auf dem Schraubenschaft drehbaren Büchse seitlich umschlossen und durch eine Plombe nach vorn abgedeckt ist.The subject of the invention is a security device against unauthorized use Loosening of screws * especially for scales, in which the screw head by means of a sleeve rotatable on the screw shaft and laterally enclosed by a Seal is covered at the front.

Die Erfindung ist wesentlich dadurch gekennzeichnet, daß zwecks an sich bekanntem Einpressen der Plombiermasse in den diese sowie den Schraubenkopf aufnehmenden Hohlraum der Büchse selbst eine auf einem Ansatz derselben ruhende und den unteren Abschluß für die Plombiermasse bildende »5 Platte mit Spiel über dem Schraubenkopf angeordnet ist, so daß — im Gegensatz zu den bisherigen Plombierungen von Schraubenköpfen — auch nach dem Einpressen der Plombe in die Büchse selbst, diese ohne Mitao nähme des Schraubenkopfes gedreht werden kann, νThe invention is essentially characterized in that for the purpose of what is known per se Pressing the sealing compound into the cavity of the bushing itself that accommodates this and the screw head, one on top of the other Approach of the same resting and forming the lower end for the sealing compound »5 plate is arranged with play above the screw head so that - in contrast to the previous seals of screw heads - even after the Seal in the box itself, this can be turned without mitao taking the screw head can, ν

Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht.The invention is illustrated by way of example in the drawing.

Die Teile A und B stehen durch dieParts A and B stand through the

as Schraube C miteinander in Verbindung, deren Schulter F auf die Unterlagscheibe H drückt.he screw C together, the shoulder F of which presses on the washer H.

Der Bund D der Schraube C nimmt die Plombenbüchse G auf, und zwar so, daß sich die Büchse G stets frei auf der Schraube drehen kann.The collar D of the screw C takes the lead seal sleeve G in such a way that the sleeve G can always rotate freely on the screw.

Die Büchse G besitzt einen Absatz N, aufThe sleeve G has a shoulder N on

den eine Scheibe M gelegt wird, die jedoch den Schraubenkopf E nicht berührt, da sich der Absatz N in genügendem Abstand von dem Schraubenkopf B befindet.which a washer M is placed, but which does not touch the screw head E , since the shoulder N is at a sufficient distance from the screw head B.

Der von dem Absatz N ausgehende Innenrand K der Büchse G ist in an sich bekannter Weise schwalbenschwanzförmig ausgebildet, so daß eine in den Hohlraum O der Büchse G eingesetzte und dort verstemmte Bleiplombe gegen Herausnahme gesichert ist.The inner edge K of the sleeve G starting from the shoulder N is dovetail-shaped in a manner known per se, so that a lead seal inserted into the cavity O of the sleeve G and caulked there is secured against removal.

Obwohl die Büchse G ohne weiteres gedreht werden kann, ist es unmöglich, dadurch die Schraube C zu lockern, d. h. es ist ausgeschlossen, ohne Verletzung der auf der Oberfläche mit einem Stempel o. dgl. versehenen Plombe zu dem Innern beispielsweise einer Waage zu gelangen.Although the sleeve G can be rotated easily, it is impossible thereby to loosen the screw C , ie it is impossible to get to the inside of a scale, for example, without damaging the seal on the surface with a stamp or the like.
