Description

Die vorliegende Erfindung bezieht sich auf einen Steckschlüsseleinsatz mit einem Betätigungsende, einem Verbindungsende und einer mittleren Bohrung sowie einem elastischen Teil, wobei

  • der Steckschlüsseleinsatz in der Betätigungsöffnung des Betätigungsendes eine Längsnut jeweils auf beiden gegenüberliegenden Seiten der Innenwand und eine ringförmige Nut aufweist,
  • das elastische Teil einen vorstehenden Abschnitt an einem Haltearm und einen gebogenen Kopfabschnitt aufweist, so daß der Haltearm des elastischen Teils in beide gegenüberliegenden Längsnuten gedrückt wird und der vorstehende Abschnitt aus der Wandfläche am Betätigungsende vorspringt und fest gegen eine Schraubenmutter gedrückt wird.
The present invention relates to a socket insert with an actuating end, a connecting end and a central bore and an elastic part, wherein
  • the socket wrench insert in the actuating opening of the actuating end has a longitudinal groove on both opposite sides of the inner wall and an annular groove,
  • the elastic member has a protruding portion on a support arm and a curved head portion so that the support arm of the elastic member is pressed into both opposite longitudinal grooves and the projecting portion protrudes from the wall surface at the operating end and is pressed firmly against a nut.

Ein derartiger Steckvschlüsseleinsatz ist aus dem deutschen Gebrauchsmuster 296 12 327 bekannt. Da das Teil 24 (s. Fig. 5 und 6) beim Zusammensetzen verformbar ist, kann der Haltearm 241 am Betätigungsende 22 entlang der Längsnut 221 in den Steckschlüsseleinsatz 20 hineingedrückt werden. Nach dem Einsetzen ist der Endabschnitt 244 von dem elastischen Teil 24 genau in die ringförmige Nut 222 am Betätigungsende 22 fest hineingedrückt. Da der Kopfabschnitt 243 eine halbkreisförmige Gestalt aufweist, kann das Teil 24 der mittleren Bohrung 23 ausweichen und entlang ihrer Außenumfangswandfläche hineingeführt werden. Mittels des vorstehenden Abschnitts 242 am Haltearm 241 wird eine Schraubenmutter 25 nach dem Einsetzen in das Betätigungsende 22 des Steckschlüsseleinsatzes 20 mit Hilfe von Spannung festgezogen, so daß sie sich nicht lösen kann. Da zusätzlich der Endabschnitt 244 von dem elastischen Teil 24 in die ringförmige Nut 222 gedrückt wird, kann das Teil 24 bei der Herausnahme der Schraubenmutter 25 nicht herausrutschen. Außerdem können Schraubenbolzen hineingesteckt werden, so daß das Betätigungsende 22 des Steckschlüsseleinsatzes 20 eine Verschraubungsfunktion aufweist.Such a socket wrench insert is from German utility model 296 12 327 known. Since part 24 (see FIGS. 5 and 6) is deformable when assembled, can the holding arm 241 at the actuating end 22 along the longitudinal groove 221 in the Socket wrench insert 20 are pressed in. After the insertion is the End portion 244 of the elastic member 24 exactly into the annular groove 222 on Actuating end 22 pressed firmly. Since the head portion 243 is a has a semicircular shape, the part 24 of the central bore 23 dodge and be introduced along their outer peripheral wall surface. By means of the projecting section 242 on the holding arm 241, a Nut 25 after insertion into the operating end 22 of the Socket wrench insert 20 tightened with the help of tension so that it is not can solve. In addition, since the end portion 244 from the elastic member 24 into the annular groove 222 is pressed, the part 24 when removing the Do not slide the nut 25 out. You can also use bolts be inserted so that the actuating end 22 of the socket wrench insert 20 has a screw function.

Es hat sich erwiesen, daß die Produkte von dem obengenannten Gebrauchsmuster das vorgesehene Ziel und die vorgesehene Wirkung hinsichtlich der Herstellung und der Anwendung erreicht haben. Die Produkte weisen jedoch die folgenden Nachteile auf: Wenn der Haltearm 241 in die Längsnut 221 eingesetzt wird, ist das Zusammensetzen beim Hineindrücken des elastischen Teiles 24 in den Steckschlüsseleinsatz 20 wegen des gebogenen Endabschnittes 244 am Ende des Teils 24 nicht so leicht und kann dadurch die Herstelleffizienz nicht erhöht werden, weil der Endabschnitt 244, der ortsfest in die ringförmige Nut 222 des Steckschlüsseleinsatzes 20 gedrückt wird, um ein Herausfallen aus dem Steckschlüsseleinsatz 20 zu vermeiden, jeweils an beiden Endabschnitten 244 des Teils 24 vor dem Zusammensetzen des elastischen Teils mit dem Steckschlüsseleinsatz bei dem vorgenannten Gebrauchsmuster gebogen werden muß. Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, einen Steckschlüsseleinsatz bereitzustellen, der einfacher herstell- und zusammensetzbar ist.It has been found that the products of the above utility model the intended objective and effect with regard to manufacture and of the application. However, the products have the following disadvantages open: If the holding arm 241 is inserted into the longitudinal groove 221, that is Assemble when pushing the elastic part 24 into the Socket wrench insert 20 because of the bent end portion 244 at the end of Part 24 not so easy and therefore the manufacturing efficiency cannot be increased, because the end portion 244, which is stationary in the annular groove 222 of the Socket wrench insert 20 is pressed to prevent it from falling out To avoid socket wrench insert 20, in each case at both end sections 244 of the Part 24 before assembling the elastic part with the Socket wrench insert must be bent in the aforementioned utility model. The present invention is therefore based on the object To provide socket wrench insert that is easier to manufacture and assemble is.

Erfindungsgemäß wird diese Aufgabe durch einen Steckschlüsseleinsatz nach Anspruch 1 gelöst. Im Erfindungsgemäßen Steckschlüsseleinsatz ist die ringförmige Nut im Bodenbereich des Betätigungsendes ausgebildet und der bogenförmige Kopfabschnitt wird ortsfest in die ringförmige Nut gedrückt und entlang der Außenumfangsfläche der mittleren Bohrung geführt. Dadurch wird das Ziel erreicht, das elastische Teil ortsfest am Betätigungsende des Steckschlüsseleinsatzes zu halten. Da die Bildung des gebogenen Endabschnittes am Ende des Haltearms nicht mehr nötig ist, wird die Herstellung vereinfacht, und da es leicht ist, den Haltearm ohne gebogenen Endabschnitt in die Längsnut des Steckschlüsseleinsatzes hineinzudrücken, wird das Zusammensetzen erheblich erleichtert.According to the invention this object is achieved by a socket wrench insert according to claim 1. In the socket wrench insert according to the invention, the annular groove is in the Bottom region of the actuating end and the arcuate Head section is pressed into the annular groove and along the Outer circumferential surface of the middle hole. This will make the goal reached, the elastic part stationary at the actuating end of the socket wrench insert to keep. Because the formation of the curved end portion at the end of the support arm is no longer necessary, the production is simplified, and since it is easy to Holding arm without a curved end section in the longitudinal groove of the socket wrench insert pushing it in, assembly is made considerably easier.

In den Zeichnungen ist ein Steckschlüsseleinsatz mit 20, ein Verbindungsende mit 21, ein Betätigungsende mit 22, eine mittlere Bohrung mit 23, eine Längsnut mit 221, eine ringförmige Nut mit 222, ein elastisches Teil mit 24, ein Haltearm mit 241, ein vorstehender Abschnitt mit 242, ein gebogener Kopfabschnitt mit 243, ein Endabschnitt mit 244 und eine Schraubenmutter mit 25 bezeichnet.In the drawings is a socket wrench insert with 20, a connection end with 21, an actuating end with 22, a central bore with 23, a longitudinal groove with 221, an annular groove with 222, an elastic part with 24, a holding arm with 241, a protruding section at 242, a curved head section at 243 End portion designated 244 and a nut 25.

Wie es in Figuren 1 und 2 gezeigt ist, sind bei einer besonderen Ausführungsform des erfindungsgemäßen Steckschlüsseleinsatzes 20 jeweils auf beiden gegenüberliegenden Seiten der Innenwand eine Längsnut 221 und im Bodenbereich des Betätigungsendes 22 eine ringförmige Nut 222 vorgesehen. Da ein elastisches Teil 24 am Haltearm 241 einen vorstehenden Abschnitt 242 und im Kopfabschnitt 243 eine halbkreisförmige Gestaltung aufweist und dadurch beim Zusammensetzen verformbar ist, kann der Haltearm 241 entlang der Längsnut 221 am Betätigungsende 22 in den Steckschlüsseleinsatz 20 hineingedrückt werden. Anstelle des Endabschnittes bei der aus dem eingangs beschriebenen Gebrauchsmuster bekannten Klemmweise wirkt das elastische Teil 24 mit seinem Kopfabschnitt 243 mit dem Steckschlüsseleinsatz 20 zusammen, um die Klemmfunktion zu realisieren. Dadurch kann sowohl die Bildung des Endabschnittes am elastischen Teil 24 eingespart als auch der Haltearm 241 des elastischen Teils 24 sehr leicht in die Längsnut 222 des Steckschlüsseleinsatzes gedrückt werden, wodurch das Zusammensetzen erheblich erleichtert wird, weil der Haltearm keinen Endabschnitt aufweist. Wie es in Fig. 3 gezeigt ist, wird eine Schraubenmutter 25 am Betätigungsende 22 des Steckschlüsseleinsatzes 20 geklemmt, wobei der vorstehende Abschnitt 242 am Haltearm 241 vom elastischen Teil 24 mit Hilfe von Spannung fest gegen die Schraubenmutter 25 gedrückt wird, so daß die Schraubenmutter 25 nicht leicht aus dem Steckschlüsseleinsatz herausfallen kann. Wie es in Fig. 4 dargestellt ist, weist der Kopfabschnitt 243 vom elastischen Teil 24 eine halbkreisförmige Gestaltung auf, die in der inneren ringförmigen Nut 222 festgeklemmt ist. Dies führt dazu, daß das elastische Teil 24 noch ortsfest am Betätigungsende 22 des Steckschlüsseleinsatzes 20 bleibt, wenn die Schraubenmutter 25 den Haltearm 242 vom elastischen Teil 24 verläßt und aus dem Betätigungsende 22 des Steckschlüsseleinsatzes 20 herausgenommen wird. Dadurch wird eine Klemm- und Anschlagfunktion erreicht.As shown in Figures 1 and 2, are in a particular embodiment of the socket wrench insert 20 according to the invention on both opposite Sides of the inner wall a longitudinal groove 221 and in the bottom area of the Actuating end 22 is provided an annular groove 222. Because an elastic part 24 on the holding arm 241 a projecting section 242 and in the head section 243 has a semicircular design and thus when assembling is deformable, the holding arm 241 along the longitudinal groove 221 at the actuating end 22 are pushed into the socket wrench insert 20. Instead of End section in the known from the utility model described above The elastic part 24 clamps with its head section 243 with the Socket wrench insert 20 together to realize the clamping function. Thereby Both the formation of the end section on the elastic part 24 can be saved as also the holding arm 241 of the elastic part 24 very easily in the longitudinal groove 222 of the Socket wrench insert can be pressed, making the assembly considerably is facilitated because the holding arm has no end portion. As in Fig. 3 is shown, a nut 25 at the actuating end 22 of the Socket wrench insert 20 clamped, the projecting portion 242 on Holding arm 241 from the elastic part 24 with the help of tension firmly against the Nut 25 is pressed so that the nut 25 is not easily out the socket wrench insert can fall out. As shown in Fig. 4, points the head section 243 of the elastic part 24 has a semicircular design, which is clamped in the inner annular groove 222. This leads to the fact that elastic part 24 is still stationary at the actuating end 22 of the socket wrench insert 20 remains when the nut 25 holds the arm 242 from the elastic member 24 leaves and removed from the actuating end 22 of the socket wrench insert 20 becomes. This creates a clamping and stop function.
