Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a centrifuge tube rack suitable for water bath comprises a bottom plate 1, wherein the cross section of the bottom plate 1 is rectangular, stand columns 2 are arranged at four corners of the top end face of the bottom plate 1, the centrifuge tube rack also comprises a lifting frame 3, the lifting frame 3 comprises an upper plate 4 and a lower plate 5, the upper plate 4 and the lower plate 5 are connected into an integral structure through a telescopic rod 6, connecting sleeves 7 are arranged at the outer edges of the upper plate 4 and the lower plate 5, the connecting sleeves 7 are movably sleeved on the stand columns 2 corresponding to the positions of the connecting sleeves 7, locking mechanisms 8 are further arranged on the lower plate 5, a plurality of positioning holes 9 distributed along the longitudinal direction at equal intervals are formed in the stand columns 2, locking holes 10 are formed in the connecting sleeves 7, a plurality of centrifugal tube holes 22 distributed in an array manner are formed in the upper plate 4, and rubber rings 23 are further arranged in the centrifugal tube holes 22,

The inside of bottom plate 1 is provided with the cavity, the opening 21 of cavity is seted up on the lateral wall of bottom plate 1, the cavity can hold upper cover 17.

The utility model discloses centrifuge tube rack's suitable for water bath working process as follows: firstly, experimental substances are put into a centrifugal tube, then a top cover is plugged at the tube opening of the centrifugal tube, the centrifugal tube is inserted into a centrifugal tube hole 22 formed in an upper plate 4, the bottom of the centrifugal tube is in contact with a lower plate 5, when the length of the centrifugal tube needing to be fixed is relatively long, the upper plate 4 can be lifted upwards, and all telescopic rods 6 are extended, so that the upper plate 4 can be kept stable in a water bath process even if the centrifugal tube is long;

when the heights of all centrifuge tubes need to be adjusted, an operator only needs to simultaneously stir the shift levers 14 at the tops of the two stirring pieces 13 to enable the two stirring pieces to move oppositely, so that the stirring pieces 13 can be driven to be recovered, at the moment, the bolts 16 are recovered together, the locking relation between the connecting sleeve 7 and the upright post 2 is removed, the lifting frame 3 can be driven to integrally move longitudinally relative to the upright post 2 in the state, after the height is adjusted to be proper, the shift levers 14 are released, the two stirring pieces 13 move outwards again under the action of the springs 12, the bolts 16 are popped out and inserted into the locking holes 10 and the positioning holes 9 corresponding to the two stirring pieces in the state, the connecting sleeve 7 and the upright post 2 are locked again, and at the moment, the lifting frame 3 stays at the current height;

after all the centrifuge tubes are prepared, the upper cover 17 in the cavity is drawn out from the opening 21, the upper cover 17 is buckled on the upper plate 4, the screw rod 19 penetrates into the connecting hole 18 formed in the upper cover 17, the compression nut 20 is screwed into the screw rod 19, the compression nut 20 is screwed until the compression nut 20 is contacted with the upper cover 17, and the upper cover 17 is compressed; that is to say, inside all centrifuge tube mouth of a pipe department's top cap all was located upper cover 17, even if like this the top cap of centrifuge tube collapses out under the effect of the intraductal steam of centrifuge, first can not splash everywhere, causes experimenter's injury or the damage of water-bath, and the water of second water bath usefulness also can not enter into inside the centrifuge tube.
