It extends to the bottom of the frame 9 and is slidably connected to the bottom of the frame 9. A bearing bar 11 is fixedly installed on the output shaft of the cylinder 10. Two through grooves 12 are provided on the bearing bar 11. Insert blocks 13 are installed in the two through grooves 12 by bolts, and hollow plates 14 are fixedly installed at the bottom of the two insert blocks 13. A rotating shaft 15 is rotatably installed at the bottom of the two hollow plates 14. A pressing plate 16 is fixedly installed at the bottom of the two rotating shafts 15. A protective pad 17 is fixedly installed at the bottom of the two pressing plates 16, and the bottom of one of the protective pads 17 contacts the tops of multiple test tubes 8. In this way, the openings of the test tubes 8 can be blocked, and the rotating shaft 15 and the hollow plate 14 can be rotatably installed to rotate with the rotation of the centrifuge table 4, which will not affect the blocking effect. A transverse movement mechanism is provided on the mounting table 1 to drive the two pressing plates 16 to perform a transposition operation.
[0026] The transverse movement mechanism adopted above includes a vertical plate 18, which is fixedly installed on the top of the mounting platform 1, and a cross beam 19 is fixedly installed on the top of the vertical plate 18, and a U-shaped frame 20 is fixedly installed on the bottom of the cross beam 19, in which a traveling screw 21 is rotatably installed, and a slide 22 is threadedly installed on the traveling screw 21, and the bottom of the slide 22 is fixedly connected to the frame 9, and in order to ensure the stability of the linear sliding of the slide 22, two reinforcing rods are fixed in the U-shaped frame 20, and the two reinforcing rods both penetrate the slide 22 and are slidably connected thereto, and a motor 2 is fixedly installed on the outer wall of one side of the U-shaped frame 20, and the output shaft is fixedly connected to one end of the traveling screw 21.

[0028] The working principle of the centrifugal device for medical examination provided by the utility model is as follows:
[0029] In the initial state, the output shaft of the cylinder 10 is in a retracted state, that is, both protective pads 17 are located above the centrifugal box 2;
[0030] When the sample needs to be centrifuged, the motor 2 is first started forward, and its output shaft drives the travel screw 21 to rotate. At this time, by using the threaded fit between the motor 2 and the slide 22, the slide 22 can be moved horizontally, and then the two pressing plates 16 can be moved horizontally. After the pressing plates 16 originally located above the centrifuge box 2 are taken away from the top of the centrifuge box 2, the corresponding number of test tubes 8 can be inserted into the corresponding test tube slots 6, and then the corresponding number of top screws are screwed to fix the corresponding test tubes 8.
[0031] Then, the motor 2 is started in reverse to bring one of the protective pads 17 to the top of the centrifuge box 2 again, and then the output shaft of the cylinder 10 is started to extend, and the protective pad 17 is brought down to the centrifuge box 2, and finally it is tightly attached to the top ports of multiple test tubes 8, and then the motor 1 is started, and the central shaft 3 can be driven to rotate by the meshing of the two gears, and then the centrifuge table 4 can be driven to rotate, so that the samples in the test tubes 8 can be centrifuged, and during the processing, due to the rotation connection between the rotating shaft 15 and the hollow plate 14, the corresponding pressing plate 16 and the protective pad 17 are also rotated, so as to ensure that during the centrifugation process, the ports of the test tubes 8 are always blocked to prevent the samples inside from splashing out;
[0032] After a batch of samples are centrifuged, the output shaft of the air cylinder 10 is first started to retract, and the corresponding protective pad 17 is taken out of the centrifugal box 2. Then, the motor 2 is started in the forward direction to bring the protective pad 17 out from the top of the centrifugal box 2, and then the test tube 8 is removed, and then the next batch of test tubes 8 to be centrifuged are installed. Then, the motor 2 is started in the reverse direction to bring the unused protective pad 17 to the top of the centrifugal box 2, and then the output shaft of the air cylinder 10 is started to extend, and it is brought into the centrifugal box 2 to seal the opening of the test tube 8, and then the centrifugation process can be continued;
[0033] During the centrifugal treatment process, for the previously used protection pad 17, first remove the bolts on the corresponding plug block 13, remove it together with the corresponding hollow plate 14, and then disinfect and clean the protection pad 17. After the disinfection and cleaning is completed, reinstall it on the supporting bar 11, and then wait for the previous batch of test tubes 8 to complete the centrifugal operation. After the previous batch of test tubes 8 completes the centrifugal operation, the cleaned protection pad 17 can be used again, and the used protection pad 17 can be disassembled and disinfected and cleaned. In this way, the two protection pads 17 are used alternately, so that the used protection pad 17 can be disinfected and cleaned without delaying the centrifugal treatment.
[0034] Compared with the related art, the centrifugal device for medical examination provided by the utility model has the following beneficial effects:
[0035] The utility model provides a centrifugal device for medical inspection. By installing two pressing plates 16 and a protective pad 17 on a bearing bar 11, the two protective pads 17 can be used alternately through the operation of a second motor. When one of the protective pads 17 is used to seal a batch of test tubes 8, the protective pad 17 can be removed and disinfected and cleaned on the other side after use, thereby greatly improving the working efficiency of centrifugal treatment of batch samples. In addition, the protective pad 17 can completely seal the opening of the test tube 8 to effectively prevent the test sample from splashing out.
