Description

lur> ist bereits eine Feststellschraube mit Mehrkantkopf bekannt, bei welcher auf der Schraube eine Zwischenuiutter und auf dieser eine Feststellschraube sitzt. Diesem Durihbildun.^ vermochte aber keinesfalls der Forderung I zu genügen, ein Loekerwerden der Schrauben bei Erschütterungen zu verhindern, üs ist auch bekannt, die Schraubenvere'ruiiung durch Beilagsdieiben, rfperringe, Kontermuttern u.dgl. .xuszuschalten. Bei schweren und dauernden Erschütterungen genügen auch uiese Maßnahmen nicht. lur> a locking screw with a polygonal head is already known, in which an intermediate nut sits on the screw and a locking screw sits on this. However, this development was in no way able to meet requirement I of preventing the screws from loosening in the event of vibrations; In the case of severe and permanent vibrations, even these measures are not sufficient.

Aufgabe dar Erfindung ist es, eine Feststellschraube zu schaffen, die ein Loekerwerden der Schrauben, selbst bei Vibrationen und schwersten Erschütterungen, verhütet.Object is the invention is to provide a locking screw, which, even with vibrations and severe vibrations, preventing an Loekerwerden of the screws.

Erf indungsgetiäß wird eine Feststellschraube Mit Mehrkantkopf, bei welcher auf der Schraube eine Zwischenmutter und auf dieser eine Feststellschraube sitzt, in Vorschlag gebracht, die dadurch gekennzeichnet ist, daß eine Zwischeniiiutter mit uiittiger Längsteilung zwei gegenüberliegende Spalte bildet, daß ihre Gewindeaußenfläche schwach kegelig zu der der Schraube und ihre Gewindeganghöhe kleiner als die der Schraube und ihr Innengewinde durchgebildet ist und daß auf ihr eine entsprechende Mutter aufschraubbar ist.According to the invention, a locking screw with a polygonal head, in which there is an intermediate nut on the screw and a locking screw on this, in the proposal brought, which is characterized in that an intermediate nut with longitudinal division two opposite one another Gap forms that their outer thread surface is weak conical to that of the screw and its thread pitch smaller than that of the screw and its internal thread is and that a corresponding nut can be screwed onto it.

In der Zeichnung ist die Erfindung beispieIsneise veranschaulicht, und zwar zeigen:In the drawing, the invention is illustrated by way of example, namely show:

Fig, 1 die Ansicht der Feststellschraube mit einer Zwischenmut terhälfte mit geschnittener Mutter undFig, 1 is a view of the locking screw with an intermediate nut half with cut nut and

Fig. 2 eine Ansicht der Feststellschraube.Fig. 2 is a view of the locking screw.

Auf der Feststellschraube 1 mit Mehrkantkopf und Gewindegang 2 sitzen mit entsprechendem Innengewinde zwei Hälften 3, k einer Zwischeniautter mit Liehrkantkopf, die zwei gegenüberliegende Spalte 5 bilden. Die Außenfläche ihres Gewindes verläuft schwach kegelig zum Gewindegang 2 der Schraube, und außerdem ist ihre Gewindeganghöhe kleiner als die der Schraube. Auf der Zwischenmutter sitzt eine entsprechend durchgebildete Mutter 7·On the locking screw 1 with a polygonal head and thread 2, two halves 3, k of an intermediate nut with a recessed head, which form two opposing gaps 5, sit with a corresponding internal thread. The outer surface of its thread is slightly tapered to thread 2 of the screw, and its thread height is also smaller than that of the screw. A correspondingly formed nut 7 sits on the intermediate nut

Infolge der verschiedenen Gewindegänge 2» 6 und der längsgeteilten Zwischenmutter ist eine außerordentlich feste Sehraubenverbindung geschaffen, die durch Erschütterungen, Vibrationen u.dgl. nicht gelockert wird, Andererseits ist ein leichtes und schnelles Lösen dieser Schraubenverbindung gewährleistet. Sie eignet sich hervorragend bei schweren Werkzeugmaschinen, bei militärischen Brücken, die schnell montiert und demontiert werden müssen, bei Fahrzeugen aller Art usw.Due to the different thread turns 2 »6 and the longitudinally split intermediate nut, one is extraordinary Fixed visual connection created that is not loosened by shocks, vibrations and the like, On the other hand, an easy and quick loosening of this screw connection is guaranteed. She is suitable excellent for heavy machine tools, for military bridges that are quickly assembled and disassembled must be, for vehicles of all kinds, etc.
