Description

Schraubenmuttersicherung Vorliegende Erfindung kennzeichnet eine Kapselsicherung für Schraubenmuttern, bei welcher durch Rechts- bzw. Linksdrehen der Kapsel- c die Mutter a gesichert und auf dieselbe Weise auch wieder entsichert werden kann.Nut lock The present invention features a capsule lock for screw nuts, in which by turning the capsule to the right or left c the Mother a secured and can be unlocked again in the same way.

Der Gegenstand der Erfindung ist in der beiliegenden Zeichnung beispielsweise in einer Ausführungsform dargestellt, und zwar zeigt Abb. x den Längsschnitt durch die Kapselsicherung, Abb. 2 den Langschnitt durch die Kapsel c, Abb. 3 einen Querschnitt nach Linie A-A der Abb, z.The object of the invention is in the accompanying drawing, for example shown in one embodiment, namely Fig. x shows the longitudinal section through the capsule lock, Fig. 2 the long section through the capsule c, Fig. 3 a cross section according to line A-A of the figure, e.g.

Die eigentliche Schraubenmutter a hat einen rohrförmigen Ansatz b. In den rohrförmigen Ansatz b wird eine Kapsel c eingeschoben, mit der das eine Ende f einer Spannfeder e fest verbunden ist, während das andere Ende g der Feder e an der Schraubenmutter a befestigt ist. Die Kapsel besitzt in ihrem inneren Teil einen Querbolzen d, durch den die Kapsel nach Art eines Bajonettverschlusses mit dem Bolzenende verbunden wird. Zum besseren Erfassen der Kapsel dient der schmale Ansatz k.The actual screw nut a has a tubular extension b. A capsule c is inserted into the tubular extension b, with which one end f of a tension spring e is firmly connected, while the other end g of the spring e is fastened to the screw nut a. In its inner part, the capsule has a transverse bolt d, by means of which the capsule is connected to the bolt end in the manner of a bayonet lock. The narrow attachment k is used to better grasp the capsule.

Der Gebrauch der Kapselsicherung ist folgender: Die Mutter a wird auf den Schrauben-;;:)lzen h aufgesetzt und angezogen, wobei der Bolzen d der Kapsel c außerhalb des Schlitzes i bleibt. Die Kapsel wird dann in Drehrichtung der angezogenen Schraubenmutter zwecks Spannung der Feder e mehrmals gedreht, dann nach unten gedrückt, wobei der Bolzen d in den Schlitz i eingeschoben wird. Ist der Bolzen d am Ende des Schlitzes i angelangt, so wird die Kapsel c bei Freigabe derselben unter Einwirkung der Federspannung um 9o ° gedreht, wobei sich derBolzend unter Federspannung in die seitlichen Einschnitte j -legt. Durch mehlmaliges Drehen der Kapsel wird also die Feder e gespannt, so daß die Mutter a gegenüber dem Schraubenbolzen j stets unter Spannung der Feder e steht und die Mutter gegen Rückdrehung gesichert ist.The use of the capsule lock is as follows: The nut a is placed on the screws - ;; :) lzen h and tightened, whereby the bolt d of the capsule c remains outside the slot i. The capsule is then turned several times in the direction of rotation of the tightened screw nut for the purpose of tensioning the spring e, then pressed downwards, the bolt d being pushed into the slot i . When the bolt d has reached the end of the slot i, the capsule c is rotated 90 ° under the action of the spring tension when it is released, the bolt end being laid under the spring tension in the lateral incisions j. By turning the capsule a few times, the spring e is tensioned so that the nut a is always under tension of the spring e with respect to the screw bolt j and the nut is secured against reverse rotation.
