Definitions
- the present invention relates to a lid for closing a centrifuge rotor.
- Centrifuges are devices with which containers can be exposed to centrifugal force. In the laboratory, for example, suspensions in test tubes can be treated to deposit the suspended solid at the bottom of the test tube. Centrifuges usually have a rotary drive with a vertical drive shaft on which a rotor can be placed. Fans are usually provided in the rotor, into which containers which are to be centrifuged can be inserted. Often the rotors of the centrifuge are interchangeable in order to centrifuge vessel contents in one of the rotors, while other rotors are first loaded with containers or can be prepared for further processing with already centrifuged containers.
- test tubes are inserted openly into the rotors on the top side, among other things, it serves to ensure the reliability of keeping the containers in a liquid-tight space during centrifugation in the rotor.
- this space should be as accessible as possible for easy loading.
- centrifuges are in need of improvement.
- the present invention has for its object to provide a lid for closing a centrifuge rotor, the handling is simplified.
- a lid for closing a centrifuge rotor is characterized by a form-fitting, rotationally actuated closing mechanism which, pre-positioned on the centrifuge rotor, automatically moves into a closed position due to the self-weight of the lid.
- a closure mechanism of the lid according to the invention the closed end position of the lid on the centrifuge rotor, in particular by a snapping or clicking sound, acoustically.
- the closure mechanism is a movement thread with a sufficiently large pitch angle
- the cover can automatically rotate into a closure position in the thread after pre-positioning at the entrance of the thread by the weight of the cover itself.
- the locking mechanism comprises a locking of the fully closed position of the lid - for example at the end of the thread.
- the lock can be positive, for example, by the lid before locking on its seals, which cause the tightness, and for example against the rubber-elastic deformability then comes to rest form-fitting manner via a Arret michsabsatz with a pin in a Arret michshinterrough.
- a shutter mechanism can be provided - somewhat similar in function as a thread - a bayonet, such as the way it is known and widely used for interchangeable lenses on SLRs. Also, it is possible to take over the spring-preloaded detent known there, also with actuating lever for releasing the detent, in principle directly for the cover according to the invention.
- Figure 1 shows a sectional side view of a centrifuge rotor and a
- FIG. 2 shows a sectional side view of the centrifuge rotor according to FIG. 1 with the cover in the (almost) closed position
- FIG. 3 shows a three-dimensional sectional view of the centrifuge rotor with dekel according to FIG. 1 and FIG. 3
- FIG. 4 shows a three-dimensional view of the closure mechanism of the centrifuge rotor according to FIG. 1.
- a centrifuge rotor 2 can be seen, above which a lid 4 is shown as it is placed by a hand (not shown) of a user on the centrifuge rotor 2.
- the centrifuge rotor 2 has a row evenly on the rotor Circumferentially distributed bores or compartments 6, while test tubes (not shown) can be stuck obliquely outward oriented down.
- the rotor is rotationally symmetrical overall about a vertical axis 8 and has in the center a vertical, central bore 9, through which the rotor 2 can be attached to a centrifuge drive shaft (not shown) for centrifuging.
- the compartments 6 for test tubes are accessible through a large circular opening 10 in the upper side of the rotor 2. They are located on the radial outer wall of a cup-shaped space 11 which extends in a ring around a central hub 12.
- the bore 9 is arranged for a centrifuge rotor drive shaft on the underside. Upwards, the hub 12 protrudes out of the opening 10 to a certain extent circular cylindrical and forms an essential element of a closure mechanism 14 of the lid 4:
- the lid 4 which is circular in plan view, has a circular-cylindrical upwardly protruding handle knob 16 at its upper side, which is hollow on the underside , so to speak, has the shape of a mug or hat.
- the knob 16 with the cover 4 can be gripped from above, can the knob 16 with the cover 4 in total put on the upper end 18 of the hub 12 and so pre-position. Without further rotational movement, the lid 4 falls vertically downwardly with the cup-shaped knob 16 over the upper end 18 of the hub 12 due to its own weight along the vertical axis 8 until three threaded studs 20 projecting radially inwards into the cup-shaped knob, which evenly the periphery of the interior 22 of the cup-shaped knob 16 are distributed to come to rest on the upper edge of the upper end 18 of the hub 12.
- the cover 4 slips further down along the vertical axis 8 due to its own weight and is thereby offset by a three-start thread 24 in a rotary movement in a clockwise direction.
- the three-start thread 24 in the hub 12 is particularly well recognizable in the spatial view of Figure 4.
- the three-flighted thread 24, as viewed in FIG. 4, spirally extends downward in the form of three helical grooves 24 on the circumference of the hub 12.
- the grooves 24 have such a width that the threaded pin 20 in the interior of the cup-shaped knob 16 out, but without clamping, can run in it.
- the cover 4 moves automatically by its own weight, rotating about the vertical axis 8, down until its O-ring seal 26 (bottom side at the extreme edge of the lid) comes to rest on the upper edge of the rotor opening 10.
- This position of the cover 4 on the rotor 2 can be seen in FIG.
- the threaded studs 20 By actively turning the cover 4 further, guided by its threaded studs 20 in the threads 24, the threaded studs 20 now overcome the shoulders or “bosses" 28 against the prestressing of the rubber-elastic seal 26 which is liquid-tight in a sealing groove 30 on the outer edge of the rotor opening 10 Behind the bosses 28, the threaded pins 20 are then locked in a form-locking manner in the locking positions 27 at the end of the threads 24.
