Claims (7)

vsozzso-s 2 Vid änden av axeln 5 finns ett genomgående stift 1, vars ändar sträcker sig ut från axeln 5 och bildar radiella utsprång, vilka åskådliggöres tydligast i fig 2. Såsom nämnts ovan sträcker sig axeln 5 in i den hattformiga hylsan 6 via ett hål 8, vilket är försett med in mot detsamma öppna urtag 9 och 10. Urtagen 9 och 10 har formen av spår, vilka är snedställda i centrifugrotorns l rotationsriktning, som i föreliggande fall är moturs enligt fig 2. Såsom framgår både i fig l och 2 har hålet 8 betydligt större diameter än axeln 5, men mindre diameter än längden på stiftet 7. Här- igenom hindras avlägsnande av locket 3 under centrifugrotorns l rota- tion. Avtagning av locket 3 kan endast ske efter det att centrifugro- torn l har stannat och locket 3 vrides tills stiftutsprângen 7 är in- riktade med urtagen 9 och 10 och föres genom dessa under viss vridning. Om centrifugrotorn l skulle börja rotera under genomföringen av stift- ursprângen 7 kommer snedställningen av utsprångsspåren 9 och 10 att föra lockat 3 tillbaka i stängt laga. ' Genom spelet mellan hålet 8 och axeln 5 medges även en viss vibration av centrifugrotorn l utan att vibrationen påverkar locket 3 i någon nämnvärd utsträckning. I Hylsan 6 kan vara tillverkad av en lämplig plast och vara fäst på centrifugrotorns l nav. Det är naturligtvis inte något som hindrar att axeln har urtagen och hylshålet utsprången, varvid axeln även uppvisar ett spår, vilket förbinder urtagen och i vilket utsprângen löper. Antalet utsprång och urtag är naturligtvis relativt godtyck- ligt och kan väljas från fall till fall. Den i det föregående omnämnda axel 5 har såsom framgår på ritningen mera formen av en axeltapp än en egentlig axel men benämn- ningen axel har använts såsom funktionsdel i kopplingen. PATENTKRAVAt the end of the shaft 5 there is a continuous pin 1, the ends of which extend from the shaft 5 and form radial projections, which are most clearly illustrated in Fig. 2. As mentioned above, the shaft 5 extends into the hat-shaped sleeve 6 via a hole 8, which is provided with towards the same open recesses 9 and 10. The recesses 9 and 10 are in the form of grooves which are inclined in the direction of rotation of the centrifuge rotor 1, which in the present case is counterclockwise according to Fig. 2. As can be seen both in Figs. 2, the hole 8 has a considerably larger diameter than the shaft 5, but a smaller diameter than the length of the pin 7. This prevents removal of the cover 3 during the rotation of the centrifuge rotor 1. Removal of the cover 3 can only take place after the centrifugal rotor 1 has stopped and the cover 3 is rotated until the pin projections 7 are aligned with the recesses 9 and 10 and are passed through them during some rotation. If the centrifuge rotor 1 were to start rotating during the passage of the pin origin 7, the inclination of the projection grooves 9 and 10 will bring the lid 3 back in closed position. The play between the hole 8 and the shaft 5 also allows a certain vibration of the centrifugal rotor 1 without the vibration affecting the lid 3 to any appreciable extent. The sleeve 6 can be made of a suitable plastic and be attached to the hub of the centrifuge rotor 1. Of course, there is nothing to prevent the shaft from having the recesses and the sleeve hole projections, the shaft also having a groove, which connects the recesses and in which the projections run. The number of projections and recesses is of course relatively arbitrary and can be chosen from case to case. The shaft 5 mentioned above has, as can be seen in the drawing, the shape of a shaft journal more than an actual shaft, but the term shaft has been used as a functional part in the coupling.
