Abstract

The screw fastening backup structure has a hexagonal recess (5) that is formed as a negative profile portion in an outer contour region. A hole (7) is provided at an end surface of a straight-shaped or angular-shaped lobe portion (6).

Description

Die Erfindung betrifft eine Verschraubungssicherung für alle Arten von Schraubverbindungen, besonders im Bereich von Verrohrungen oder Verschlauchungen mit festen Verbindungsteilen oder Verteilern. Die Verschraubungssicherung besteht vorzugsweise aus einem dünnen Material mit anforderungsgerechter Festigkeit wie z. B. Aluminium- oder Stahlblech mit mindestens einem angesetztem Lappen und einer Bohrung für die Aufnahme eines Sicherungsdrahtes, die für die Sicherung von einer oder mehreren Verschraubungen aller Art eingesetzt werden kann.The invention relates to a screw for all types of screw, especially in the field of tubing or tubing with fixed connection parts or manifolds. The screw connection is preferably made of a thin material with requirement-strength such. As aluminum or steel sheet with at least one attached tab and a hole for receiving a fuse wire that can be used to secure one or more fittings of all kinds.

Es ist bekannt, dass einen Vielzahl von Schraubensicherungen für erhöhte Anforderungen auf zusätzlichen Bauteilen oder Sondergewinden basieren, wie in z. B. in DE 101 48 473 A1 oder DE 703 17 24 . Der erhöhte Aufwand bei Fertigung, Handhabung und Lagerhaltung macht diese Arten der Schraubensicherungen häufig unrentabel. Es ist weiterhin bekannt, dass Schraubverbindungen mit verschiedenen Arten von Klebstoffen gesichert werden können wie z. B. in DE 10 2006 030 147 . Diese Möglichkeiten der Sicherung benötigen ebenfalls einen erhöhten Fertigungs- und Montageaufwand, sind teilweise, z. B. bei Gewinden in Aluminium, nicht für Schraube und zu verschraubendes Bauteil zerstörungsfrei zu lösen oder sind, wie im Fall einer Sicherung mit Klebstoffen, nicht hochtemperatursicher und damit ausfallgefährdet für gerade die Fälle, für die die Sicherung eigentlich eingesetzt war. Ebenso unzureichend sind Schraubensicherungen wie in DE 10 2007 031 991 , bei der eine Verschraubung durch eine andere Verschraubung gesichert wird. Diese sollte, um Sicherheit zu gewährleisten, wiederum gesichert werden, was aber nicht gezeigt wird. Die genannten Probleme werden mit der Verschraubungssicherung gelöst.It is known that a variety of threadlockers for increased requirements based on additional components or special threads, as in z. In DE 101 48 473 A1 or DE 703 17 24 , The increased effort in manufacturing, handling and warehousing makes these types of threadlockers often unprofitable. It is also known that screw can be secured with various types of adhesives such. In DE 10 2006 030 147 , These ways of securing also require increased manufacturing and assembly costs, are partially, z. As in threads in aluminum, not to solve for screw and screwed to non-destructive component or, as in the case of a backup with adhesives, not high temperature and thus at risk of default for just the cases for which the fuse was actually used. Also inadequate are threadlockers as in DE 10 2007 031 991 , in which a screw is secured by another screw. This should, in order to ensure security, be secured again, but this is not shown. The problems mentioned are solved with the screw locking.

Mit der Verschraubungssicherung kann eine Vielzahl von Sicherungsaufgaben erledigt werden, insbesondere in Bereichen der Luftfahrt, im Umweltmaschinenbau und überall, wo gelegentlich hohe Belastungen auftreten wie Vibrationen und Hitze beim allgemeinen Betrieb, aber auch infolge von Betriebsstörungen wie punktuelle Überhitzung, Feuer etc., also durch Situationen, auf die nicht sofort reagiert werden kann, man sich aber gegen Folgeschäden absichern muss. Zudem kann die Verschraubungssicherung wieder verwendet werden und muß nicht nach einmaligem Gebrauch zu ersetzt werden. Die Verschraubungssicherung kann für eine einzelne Verschraubung eingesetzt werden, vorgesehen ist sie für Sicherungen von 2 oder mehr Verschraubungen gleichzeitig.With the screw locking a variety of backup tasks can be done, especially in aerospace, environmental engineering and everywhere, where occasionally high loads occur such as vibration and heat in general operation, but also as a result of malfunctions such as point overheating, fire, etc., so by Situations that can not be immediately addressed, but you have to hedge against consequential damage. In addition, the screwing can be used again and must not be replaced after a single use. The screw lock can be used for a single screw, it is intended for securing 2 or more screws simultaneously.

Die Zeichnung 1 zeigt die Verschraubungssicherung in mehreren Varianten (Zeichnung 1, 14). Hier als Sechskant gezeichnet die Aussparung (5), die alle Formen der zu sichernden Außenkontur annehmen kann. Der angesetzte Lappen (6) wobei die Verschraubungssicherung mehrere angesetzte Lappen besitzen kann, an deren Ende die Bohrung (7) zur Aufnahme eines Sicherungsdrahtes liegt. Je nach Anwendungsfall ist der Lappen am Ende abgewinkelt (8).The drawing 1 shows the screw in several variants (Figure 1, 1 - 4 ). Drawn here as a hexagon the recess ( 5 ), which can take all forms of the outer contour to be secured. The attached rag ( 6 ) wherein the screw locking can have several attached lobes, at the end of the bore ( 7 ) is located to receive a fuse wire. Depending on the application, the flap is angled at the end ( 8th ).

Im Anwendungsbeispiel wird die Verschraubung eines Verbindungsbauteils (9) mit zu- und abführendem Schlauch mit Hilfe der Verschraubungssicherung nach Form (3) gesichert. Die Verschraubungssicherungs-Bleche werden vor Montage der Rohre über die Verschraubungsprofile geschoben und nach der Montage der Verrohrung durch einen gedrillten Sicherungsdraht (10), wie er z. B. in der Luftfahrt zugelassen ist, miteinander verbunden. In diesem Fall bilden 2 Verschraubungssicherungen mit je einem angesetzten Lappen, der am Ende abgewinkelt ist, einen Sicherungsverbund.In the application example, the screw connection of a connection component ( 9 ) with incoming and outgoing hose with the help of the screw-lock safety device ( 3 ) secured. The screw-fastening sheets are pushed over the bolting profiles before the pipes are installed and, after the piping has been mounted, by a twisted safety wire ( 10 ), as he z. B. is approved in aviation, interconnected. In this case, 2 screw securing devices, each with an attached flap, which is angled at the end, form a safety bond.

Im Fall von mehr als 2 Verschraubungen, die gesichert werden müssen, wie z. B. bei einer T-Verbindung, kommen zwei Verschraubungssicherungen mit je einem Lappen nach Form (3) sowie eine Verschraubungssicherung mit 2 Lappen nach Form (4) zum Einsatz, wobei die Verschraubungssicherung mit 2 Lappen, auf den Fuß des T aufgesetzt wird, die 2 Verschraubungssicherungen mit einem Lappen auf je einen Arm des T. Die Lappen werden am Ende in Richtung der gegenüberliegenden Verschraubungssicherung angewinkelt. Damit ist eine sichere, äußerlich optisch oder nach Gefühl kontrollierbare Sicherung von Verschraubungen aller Art gegeben, die jederzeit zerstörungsfrei wieder lösbar ist.In the case of more than 2 glands that need to be secured, such as. B. in a T-connection, come two screwing fuses, each with a rag to form ( 3 ) as well as a screw connection with 2 lobes according to form ( 4 ), whereby the screw connection safety device is placed on the foot of the T with 2 lobes, the 2 screw lock safety devices with a cloth on each arm of the T. The lugs are bent at the end in the direction of the opposite screw safety device. Thus, a secure, externally visually or by feeling controllable security of screw connections of all kinds is given, which is non-destructive at any time again.
