Detailed Description
The test tube centrifuge for the automatic analyzer comprises a rotating shaft and a test tube placing card, wherein the rotating shaft is connected with the test tube placing card through an angle adjusting mechanism. The following is described by way of specific examples:
as shown in fig. 1-3, the angle adjusting mechanism of the invention comprises an outer sleeve 2 fixedly arranged on the top plate of a supporting frame 1, wherein an inner sleeve 5 is connected in the outer sleeve 2 through an upper bearing 3 and a lower bearing 3, and the inner sleeve 5 is connected with a motor 4 through a synchronous belt transmission mechanism; the inner sleeve 5 is internally provided with a rotating shaft 6 in a penetrating way, the rotating shaft 6 is provided with a compression spring 7 in a penetrating way, two ends of the compression spring 7 are respectively provided with an upper limiting block positioned on the inner sleeve 5 and a lower limiting block positioned on the rotating shaft 6, the joint surface of the lower section of the rotating shaft 6 and the inner sleeve 5 is also provided with a spline groove 8 matched with each other, and the lower part of the rotating shaft 6 is correspondingly provided with a lifting cylinder 9 arranged on the bottom plate of the support frame 1. Under the action of the motor 4 and the lifting cylinder 9, the rotating shaft 6 can realize the lifting and rotating functions; meanwhile, when the piston rod of the lifting cylinder 9 is retracted, the compression spring 7 can enable the lifted rotating shaft 6 to quickly return to the original position under the action of the upper limiting block and the lower limiting block.
As shown in fig. 2 and 3, the top of the inner sleeve 5 is connected with a rotating cage 10, the side wall of the rotating cage 10 is uniformly provided with a plurality of through holes 11, the top of each through hole 11 is provided with a horizontal connecting arm, the horizontal connecting arm is hinged with an annular test tube placing card 12, the end part of the test tube placing card 12 is connected with a rotating arm 13 extending into the through hole 11, and the included angle between the rotating arm 13 and the central shaft of the test tube placing card 12 is 30-45 degrees; the top of the rotating shaft 6 is connected with a lifting disk 14, and a plurality of articulated arms 15 correspondingly connected with the rotating arm 13 are arranged on the periphery of the lifting disk 14. When the rotating shaft 6 rises, the connecting rod mechanism formed by the rotating arm 13 and the articulated arm 15 gradually enables the test tube placing card 12 to be horizontally arranged (see figure 2), so that the vertical sample injection of the pipette gun is facilitated; in the descending process of the rotating shaft 6, the upper end surface of the test tube placing card 12 gradually rotates from the vertical direction to the center direction of the lifting disc 14, so that the centrifugal force applied to the test tube is adapted to the rotating speed of the lifting disc 14. In order to adapt to the displacement change of the test tube, the middle part of the rotating cage 10 is in a necking cylindrical structure, and a long hole corresponding to the test tube placing card 12 is formed in an upper cover arranged on the top of the rotating cage 10.
When the test tube rack is used, a test tube is inserted into the test tube rack 12, and then the piston rod of the lifting cylinder 9 pushes the rotating shaft 6 upwards, the lifting disk 14 ascends to enable the articulated arm 15 and the rotating arm 13 to be linked, so that the test tube is in a vertical sample injection position; after the sample injection is finished, the lifting cylinder 9 is deflated, the piston cylinder is separated from the bottom of the rotating shaft 6, meanwhile, the motor 4 is started to drive the rotating shaft 6 to rotate, and the rotating shaft 6 moves downwards under the action of restoring force of the compression spring 7, so that the opening of the test tube gradually inclines towards the rotating center and is adapted to centrifugal force.
