As shown in fig. 1 to 5, when the apparatus of the present invention is in the initial state, the shift pulley 11 tightly supports the lower belt 31, the upper belt 19 is in the relaxed state, the elastic force of the abutment block spring 58 is greater than the elastic force of the magnet block spring 63, the restriction block spring 44 is in the compressed state, and the elastic force of the restriction block spring 44 is less than the elastic force of the magnet plate spring 65;
sequence of mechanical actions of the whole device:
when the test tube balancing centrifuge starts to work, the cover 16 is opened, a test tube to be centrifuged is placed into the test tube cavity 39 from the test tube block cavity 40, the test tube block 38 overcomes the thrust of the test tube block spring 56 under the action of the gravity of the test tube to drive the connecting rod 41 to move downwards, the connecting rod 41 moves downwards and drives the rack gear 52 to rotate through the rack 55, the rack gear 52 rotates and drives the line shaft 49 to rotate through the line wheel transmission gear 53, the line shaft 49 rotates and drives the line wheel 47 to rotate, the line wheel 47 rotates and drives the counter weight 36 to move outwards through the counter weight pull rope 35 and overcomes the thrust of the counter weight spring 37, and the force formed by the movement distance of the counter weight 36 is the same as the weight of the test tube at;
then the cover 16 is closed, the time required for centrifugation is input, the motor 25 is started to rotate, the motor 25 rotates to drive the lower motor belt pulley 24 and the upper motor belt pulley 20 to rotate simultaneously through the motor shaft 22, the upper motor belt pulley 20 cannot drive the machine shell gear 13 to rotate, the lower motor belt pulley 24 can drive the lower belt transmission wheel 32 to rotate through the lower belt 31, the lower belt transmission wheel 32 rotates to drive the magnet block wheel 69 and the abutting block wheel 60 to rotate through the transmission shaft 70, because the rotation speed of the transmission shaft 70 is slow just after the beginning, the magnet block 62 can only overcome the pulling force of the magnet block spring 63 to move outwards under the action of the centrifugal force, at the moment, the magnet plate 66 overcomes the pushing force of the magnet plate spring 65 to move upwards under the action of the repulsive force of the magnet block 62, at the moment, the limiting block 45 moves inwards under the action of the pushing force of the limiting block, thereby limiting the rotation of the face gear 46 and fixing the test tube block 38 at the current position without being influenced by the centrifugal force;
when the rotating speed of the transmission shaft 70 is increased to be capable of throwing out the abutting block 59, the abutting block 59 overcomes the pulling force of the abutting block spring 58 to move outwards, so that the abutting block abuts against the inner wall of the abutting block abutting cavity 72, at the moment, the transmission shaft 70 rotates to drive the centrifugal disc 33 to rotate through the abutting block 59, and the centrifugal machine starts to work;
after the time is over, the transposition electromagnet 27 is electrified, the repelling transposition magnet 26 overcomes the thrust of a transposition magnet spring 29 and drives the transposition belt wheel 11 to move upwards through the transposition shaft 30 until the transposition belt wheel 11 is separated from the lower belt 31 and is abutted against the upper belt 19, so that the upper belt 19 is tightly supported, at the moment, the upper motor belt wheel 20 can drive the machine shell gear 13 to rotate through the upper belt 19, meanwhile, the centrifugal disc 33 stops rotating, the abutting block 59 resets under the tension of the abutting block spring 58, the magnet block 62 resets under the tension of the magnet block spring 63, the magnet plate 66 drives the limiting block 45 to move inwards through the limiting block pull rope 43 under the elastic force of the magnet plate spring 65 and overcomes the thrust of the limiting block spring 44, so that the end face gear 46 is disengaged from the limiting block 45, and the test tube block 38 is not limited;
the machine shell gear 13 rotates to drive the machine shell 18 to rotate through the machine shell shaft 15, the machine shell 18 rotates to enable water drops generated in the centrifugal disc cavity 17 due to cooling to be thrown out of the water outlet cavity 14, after a certain time, the transposition electromagnet 27 is powered off regularly, meanwhile, the motor 25 stops rotating, the transposition electromagnet 27 powered off transposition magnet 26 drives the transposition belt wheel 11 to reset under the elastic force of the transposition magnet spring 29, at the moment, the machine cover 16 can be opened to take off a test tube, and the test tube block 38 resets under the elastic force of the test tube block spring 56, so that the balance weight 36 resets.
The invention has the beneficial effects that: this device drives the weight that the rack removed judges the test tube through the test tube piece, then reach the weight of balanced both sides through the counter weight of automatically regulated symmetric position, realize the quality of automatic balance both sides, reduce the loaded down with trivial details process of artificial balance, the time of weighing has also been practiced thrift simultaneously, great improvement experimental efficiency, the risk of making the test solution when still avoiding weighing, on the other hand, centrifuge machine shell again after the test tube centrifugation, can make the liquid water that produces in the centrifuge throw away, reduce centrifuge impaired hidden danger.
