Description

Gegenstand der Erfindung ist ein Werkzeug zum L<')sen oder Befestigen von zylindrischen Gewindestiften. insbesondere von Stiftkontakten elektrischer Leistungsschalter. Befinden sich diese Gewindestifte beispielsweise in mit 01 gefüllten Schaltgefällen und ist ein seitlicher "Zugang zu den Stiften nicht vorhanden, so ist ein Lösen mit normalen Werkzeugen nicht möglich. Die Erfindung zeigt nun einen Steckschlüssel, mit dem dieses in besonders einfacher Weise vorgenommen werden kann. Erfindungsgemäß besitzt der Steckschlüssel ein haubenartig ausgebildetes Ende, das den Gewindestift umfaßt. Innerhalb der Haube befinden sich Druckrollen, die sich federnd gegen den Gewindestift anlegen und die so geführt sind, daß sie beim Rechts- oder Linksdrehen des Steckschlüssels gegen hervorstehende Innenwandungsteile der Haube auflaufen und den Gewindestift festklemmen. Auf diese Weise Kanu der Gewindestift von dem Muttergewinde gelöst und aus dem Behälter herausgenommen werden. Durch geringes Zurückdrehen wird die Klemmung beseitigt und der Gewindestift vom Steckschlüssel gelöst. Das Einsetzen des Gewindestiftes und seine Befestigung erfolgt in umgekehrter Drehrichtung.The invention relates to a tool for loosening or fastening cylindrical threaded pins. especially of pin contacts of electrical circuit breakers. If these threaded pins are located, for example, in switching gradients filled with 01 and if there is no lateral access to the pins, they cannot be loosened with normal tools. The invention now shows a socket wrench with which this can be carried out in a particularly simple manner. According to the invention, the socket wrench has a hood-like end that includes the threaded pin. Inside the hood there are pressure rollers which resiliently rest against the threaded pin and which are guided so that when the socket wrench is turned to the right or left, they run against protruding inner wall parts of the hood and Clamp the threaded pin. In this way the threaded pin can be loosened from the nut thread and taken out of the container. By turning it back slightly, the clamping is removed and the threaded pin is loosened from the socket wrench. The threaded pin is inserted and fastened in the opposite direction of rotation ung.

Eine der möglichenAusfiihrungsfornien ist in den :'\bbildungen in zwei Ansichten dargestellt. Alb. t zeigt einen Längsschnitt, Abb. 2 einen Querschnitt. a ist der Schaft des Schlüssels mit dein Schlüsselkopf b und dem haubenartigen Teil c. In diesem befinden sich Kupplungsrollend, die in zwei Ringscheiben e geführt sind, die durch die Stangen ni gehalten werden. Die Führung erfolgt durch radiale Schlitze t. Die Rollen d werden durch einen Federring g nach inneu gegen ihre Führung e oder gegen die eingeführte zvlin<lrisclie Kontaktstiftspitze la gedrückt.One of the possible designs is in the: '\ pictures in two views shown. Alb. t shows a longitudinal section, Fig. 2 a cross section. a is the shaft of the key with your key head b and the hood-like part c. In this there are clutch rollers, which are guided in two ring disks e which are held by the rods ni. The guide takes place through radial Slots t. The rollers d are inneu against their guidance by a spring ring g e or pressed against the inserted zvlin <lrisclie contact pin tip la.

Beim Rechts- und Linksdrehen des Schlitzes n-älzeir sich die Rollen d an der Wandung des zylindrischen Stiftes lt und der schräg zu dessen ZVandungsfläche verlaufenden Fläche i (Alb. 2) der Haube c.When the slot is turned to the right and left, the rollers roll d on the wall of the cylindrical pin and the inclined to its Z wall surface running surface i (Alb. 2) of the hood c.

Da die Gt'andstärke k der Haube c größer ist als die Wandstärke 1, erfolgt ein Festklemmen der Kupplungsrollen d und dadurch Mitnahme des Stiftes h. Die Spannkraft des Federringes g ist so bemessen, daß der losgeschraubte oder eingeführte Stift h durch Reibung von den Rollen d gehalten wird.Since the thickness k of the hood c is greater than the wall thickness 1, the coupling rollers d are clamped and, as a result, the pin h is carried along. The tensioning force of the spring ring g is dimensioned so that the unscrewed or inserted pin h is held by the rollers d by friction.
