Description
Sicherung einer drehbaren Stellschraube gegen Längsverschieben Die Erfindung bezieht sich auf eine Sicherung gegen Längsverschieben einer sich gegen ein Tragteil abstützenden, drehbaren Stellschraube, die mit einer unverdrehbar angeordneten Stellmutter zusammenarbeitet. Die Erfindung ist besonders bei der Einstellschraube eines Reflektors in einem Kraftfahrzeugscheinwerfer anwendbar.Securing a rotatable adjusting screw against longitudinal displacement The invention relates to a safeguard against longitudinal displacement of one against a support part supporting, rotatable adjusting screw, which is arranged with a non-rotatable Locknut cooperates. The invention is particularly useful with the adjustment screw a reflector in a motor vehicle headlight applicable.
Bei bekannten Sicherungen dieser Art ist die Einstellschraube durch eine in der Nähe ihres Kopfes angeklenmite Scheibe gesichert. Dabei ist zwischen der Scheibe und dem Widerlager eine kurze Schraubenfeder eingelegt. Zur Sicherung der Schraube gegen Längsverschieben werden also zusätzlich eine Feder und eine Scheibe benötigt, die dazu noch mit einer besonderenAnklemmvorrichtung auf demSchraubenschaft unlösbar festgeklemmt werden muß. Andere Schraubensicherungen, die zusammen mit Quadratkopfschrauben verwendet werden, deren Schaft eine Mutter trägt, sind aus federnd nachgiebigem Blech. Teile dieses Bleches bilden dabei Haken, die den Rand des vom Schraubenschaft durchdrungenen Loches in der Befestigungswand hintergreifen.In known fuses of this type, the adjusting screw is through secured a disc attached near her head. It is between A short coil spring is inserted into the disc and the abutment. To secure the screw against longitudinal displacement are therefore also a spring and a washer which is also required with a special clamping device on the screw shaft must be permanently clamped. Other threadlockers that come with Square head screws are used, the shaft of which carries a nut, are made resilient sheet metal. Parts of this sheet form hooks that form the edge reach behind the hole penetrated by the screw shaft in the mounting wall.
Aufgabe der Erfindung ist es daher, eine Sicherung und die dazugehörige Schraube in ein Schraubenloch entsprechender Größe nacheinander in derselben Richtung lediglich durch Eindrücken in dieser Richtung einsetzbar zu machen.The object of the invention is therefore to provide a fuse and the associated Screw into a screw hole of the same size one at a time in the same direction can only be used by pushing in in this direction.
Diese Aufgabe wird dadurch gelöst, daß die Sicherung aus einer einstückigen aus Kunststoff, insbesondere Polyamid, geformten Buchse besteht ' die an jeder Stirnseite. mit mindestens zwei elastisch nachgiebigen Rastschenkeln versehen ist, von denen die dem Tragteil zugekehrten Rastschenkel beim Einstecken der Buchse in ein Loch des Tragteils in an sich bekannter Weise federnd hinter den Lochrand einschnappen, während die an der anderen Stirnseite der Buchse angeordneten Rastschenkel in gleichfalls bekannter Weise nach dem Einstecken der Schraube in die Buchse mit ihren der Buchsenachse zugekehrten Rastansätzen über den Schraubenkopf greifen, der sich mit seiner Auflagefläche auf einer Gegenschulter der Buchse abstützt.This object is achieved in that the securing of a piece of plastic, particularly polyamide, molded sleeve is' attached to each end face. is provided with at least two elastically resilient locking legs, of which the locking legs facing the support part snap resiliently behind the edge of the hole when the socket is inserted into a hole in the support part in a known manner, while the locking legs arranged on the other end of the socket in a likewise known manner after inserting the screw into the socket with its locking lugs facing the socket axis, grip over the screw head, which is supported with its support surface on a counter shoulder of the socket.
Durch diese Ausbildung wird eine leichte und schnelle Herstellung der Sicherung in einem Arbeitsgang erreicht, die die Schraube bei ihrem Verdrehen ohne eine Längsverschiebungstendenz festhält und die zugleich durch Reibung in erwünschten Grenzen eine Verdrehsicherung darstellt.This training makes it easy and quick to manufacture the fuse is achieved in one operation, which the screw when it is turned holds on without a tendency to longitudinal displacement and at the same time by friction in desired Limits represents an anti-twist device.
In der Zeichnung ist ein Ausführungsheispiel des Gegenstandes der Erfindung dargestellt. Es zeigt Fig. 1 eine raumbildliche Darstellung eines aus Kunststoff hergestellten ringartigen Sicherungsteils, F i g. 2 einen Längsschnitt durch den in ein Widerlager eingesetzten Sicherungsteils samt der gegen Längsverschieben im Widerlager zu sichernden Schraube, F i g. 3 einen Teillängsschnitt durch einen Scheinwerfer mit einer Einstellschraube und ihrer Sicherung. Im Scheinwerfer nach der F i g. 3. dient eine drehbare Kopfschraube 1 züm Einstellen eines Rellektors 2. Der Scheinwerfer ist in ein topfartiges, Gehäuse 3 eingesetzt und darin vermittels eines Tragrings 4 befestigt. Die Schraube ist mit ihrem Schaft durch ein Loch 10 in einem als Tragteil und Widerlager dienenden äußeren Flansch 5 des Tragrings hindurchge.steckt und wird an ihrem Kopf 6 durch eine ringartige Buchse 7 derart gehalten, daß sie im Tragteil 5 zwar verdrehbar, aber in ihrer Längsrichtung nicht ohne weiteres verschiebbar gehaltert ist.The drawing shows an exemplary embodiment of the subject matter of the invention. 1 shows a three-dimensional representation of a ring-like securing part made of plastic, FIG . 2 shows a longitudinal section through the securing part inserted in an abutment together with the screw to be secured against longitudinal displacement in the abutment, FIG . 3 shows a partial longitudinal section through a headlight with an adjusting screw and its fuse. In the headlight according to FIG. 3. A rotatable head screw 1 is used to adjust a Rellektor 2. The headlight is inserted into a pot-shaped housing 3 and fastened therein by means of a support ring 4. The screw is passed with its shaft through a hole 10 in an outer flange 5 of the support ring serving as a supporting part and abutment and is held at its head 6 by a ring-like bushing 7 in such a way that it can be rotated in the supporting part 5 , but in its Is not held displaceably in the longitudinal direction.
Die ringartige Buchse besteht aus Polyamid und trägt an ihrer vom Widerlager abgekehrten Seite drei spreizbare Rastschenkel 8, die mit Klauen den Kopf der Schraube umfassen. An ihrer dem Widerlager zugekehrten Seite weist sie drei zusammendrückbare Rastschenkel 9 auf, deren mit Klauen versehene Flanken im Gegensatz zu denen der Rastschenkel 8 nach außen gerichtet sind. Die Rastschenkel sind je- weils am Umfang der Buchse gleichmäßig verteilt, je- doch sind die Schenkel an der einen Stirnseite der Buchse gegenüber denen an der anderen Stirnseite versetzt angeordnet.The ring-like bushing is made of polyamide and carries on its side facing away from the abutment three expandable locking legs 8, which enclose the head of the screw with claws. On its side facing the abutment, it has three compressible locking legs 9 , the flanks of which are provided with claws, in contrast to those of the locking legs 8, facing outwards. The latching limbs are in each case uniformly distributed on the circumference of the bushing, but the JE leg on one end side of the socket are arranged offset with respect to those on the other front side.
Zum Einbau der Sicherung werden lediglich zuerst die Schenkel 9 in das Loch 10 im Tragteil 5 eingesteckt, wobei die abgeschrägten Endflächen 11 der Rastschenkel 9 am Rand des Loches 10 entlanggleiten, so daß sich die Schenkel gegen die Mitte des Ringes federnd durchbiegen, bis schließlich die Klauen über den Rand des Loches 10 rasten. Daraufhin wird der Schaft der Schraube durch die Buchse 7 hindurchgesteckt. Die Schenkel 8 werden durch den Kopf der Schraube zunächst auseinander gespreizt, was durch die Abschrägungen 13 der Endflächen der Schenkel 8 erleichtert wird. Schließlich rasten die Klauen über den Rand des Schraubenkopfes und sichern so die Schraube gegen Längsverschieben in ihrem Widerlager.To install the fuse, the legs 9 are only first inserted into the hole 10 in the support part 5 , the beveled end surfaces 11 of the locking legs 9 slide along the edge of the hole 10 so that the legs bend resiliently towards the center of the ring until finally the Snap the claws over the edge of the hole 10 . The shaft of the screw is then pushed through the socket 7 . The legs 8 are first spread apart by the head of the screw, which is facilitated by the bevels 13 of the end faces of the legs 8 . Finally, the claws snap over the edge of the screw head and thus secure the screw against longitudinal displacement in its abutment.
