[0030] It should be noted that: after the test tube is placed, the controller 21 can be used to control the electric push rod 341 and the ultrasonic transducer 31 to work, and the working ultrasonic transducer 31 can smoothly convert the electric energy into mechanical energy and smoothly act on the bottom of the placement tray 3, so that the placement tray 3 can achieve ultrasonic vibration, and the working electric push rod 341 can smoothly drive the slider 34 to slide inside the guide rail 11 when it is extended;
[0031] At this time, the slider 34 sliding outward inside the guide rail 11 can smoothly squeeze the external connecting rod 33 and the placement plate 3 through the internal rotationally connected rotating frame 331, and the placement plate 3 subjected to the squeezing force can smoothly rotate eccentrically on the top of the top rod 32 through the bottom guide ring 322, and then can smoothly eccentrically swing the top test tube through the placement plate 3, and the combination of eccentric swinging and ultrasonic vibration shaking of the sample inside the test tube can improve the shaking effect of the device on the sample in the later stage;
[0032] By setting the electric slip ring 321, when the placement plate performs eccentric rotation movement in the later stage, the ultrasonic transducer 31 that rotates with the placement plate 3 can rotate smoothly through the connection with the electric slip ring 321, thereby preventing the connection wires of the ultrasonic transducer 31 from getting entangled on the outside of the top rod 32.
[0033] In the embodiments of the present invention, please refer to Figure 1 and Figure 4A fixedly connected support rod 4 is provided on one side of the top of the placement plate 3, and a fixedly connected baffle 41 and a rotatably connected baffle plate 42 are provided above the outer wall of the support rod 4, the inner wall arc surface of the baffle plate 41 and one side of the outer wall of the baffle plate 42 are provided with a fixedly connected connecting piece 421, a threaded connecting pin 411 is inserted into the outside of the baffle plate 41, and the end of the connecting pin 411 is inserted in the connecting piece 421 through a threaded structure.
[0034] It should be noted that after the test tubes are inserted into the placement rack 5, the baffle plate 42 can be controlled to rotate on the outer wall of the support rod 4 until the connecting piece 421 on the outer wall of the baffle plate 42 successfully abuts against the outer wall of the baffle plate 41 on the other side of the support rod 4, and then the connecting pin 411 can be controlled to rotate so that the connecting pin 411 can be smoothly inserted into the connecting piece 421, thereby completing the fixation of the baffle plate 42, and then the baffle plate 42 can be stably located above a number of test tubes, thereby preventing the test tubes from falling off from the inside of the placement rack 5 when the test tubes are shaken eccentrically during the later stage.
[0035] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 A plurality of fixedly connected support plates 6 are provided outside each placement hole at the top of the placement rack 5, and two fixedly connected telescopic rods 61 are provided on the opposite side walls of the plurality of support plates 6, and the ends of the two telescopic rods 61 outside the same support plate 6 are provided with the same fixedly connected guide plate 63, and a spring 62 is sleeved on the outside of the telescopic rod 61, one end of the spring 62 is fixedly connected to the outer wall of the guide plate 63, and the other end of the spring 62 is fixedly connected to the outer wall of the corresponding support plate 6, the inner wall of the guide plate 63 is an arc surface, and the upper side of the guide plate 63 is inclined outward.
[0036] It should be noted that: during use, the trumpet-shaped structure formed by the plurality of annularly distributed guide pieces 63 can smoothly expand the corresponding specifications above the placement hole inside the placement rack 5, thereby enabling the staff to insert the test tube into the placement rack 5 more accurately and quickly;
[0037] By arranging a spring 62 on the outside of the guide rod, after the test tube is inserted, the force applied by the spring 62 to the guide plate 63 can make the outer wall of the guide plate 63 smoothly collide with the outer wall of the test tube, stably clamp the test tube, and thus reduce the test tube from swinging significantly due to ultrasonic vibration or eccentric swing of the device and colliding back and forth with the placement hole inside the placement rack 5, causing the test tube to rupture.
[0038] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A controller 21 is disposed on the top of the fixed shell 2 , and controls the electrical connection with the ultrasonic transducer 31 , the electric slip ring 321 and the electric push rod 341 .
[0039] It should be noted that: through the setting of the controller 21, when it is used later, the staff can directly control the device to work through the controller 21, which can make the later operation of the device more convenient.
[0040] The working principle of the sample pre-treatment mixing device provided by the utility model is as follows:
[0041] When using the device later, the staff can first smoothly take out the sample test tube that needs to be shaken, and then directly insert the test tube into the corresponding guide piece 63 above the placement hole in the placement rack 5. Since the top of the guide piece 63 is trumpet-shaped, the corresponding specification above the placement hole inside the placement rack 5 can be smoothly expanded, so that the staff can insert the test tube into the placement rack 5 more accurately and quickly.
[0042] After the test tube is inserted, the force applied by the spring 62 to the guide piece 63 can make the outer wall of the guide piece 63 smoothly abut against the outer wall of the test tube, stably clamping the test tube, and then the staff can control the baffle plate 42 to rotate on the outer wall of the support rod 4 until the connecting piece 421 of the outer wall of the baffle plate 42 abuts against the outer wall of the baffle plate 41 on the other side of the support rod 4, and then control the connecting pin 411 to rotate, so that the connecting pin 411 is smoothly inserted into the inside of the connecting piece 421, and the baffle plate 42 is fixed, so that the baffle plate 42 can be stably located above the test tubes, so as to avoid the test tubes from falling off from the inside of the placement rack 5 when the test tubes are shaken eccentrically in the later stage;
[0043] After the test tube is placed, the controller 21 can be used to control the electric push rod 341 and the ultrasonic transducer 31 to work. The working ultrasonic transducer 31 can smoothly convert the electric energy into mechanical energy and smoothly act on the bottom of the placement tray 3 to make the placement tray 3 realize ultrasonic vibration. When the working electric push rod 341 is extended, it can smoothly drive the slider 34 to slide inside the guide rail 11.
[0044] At this time, the slider 34 sliding outward inside the guide rail 11 can smoothly squeeze the external connecting rod 33 and the placement plate 3 through the internal rotating connected rotating frame 331. The placement plate 3 subjected to the squeezing force can smoothly rotate eccentrically on the top of the top rod 32 through the bottom guide ring 322, and then can smoothly eccentrically swing the top test tube through the placement plate 3. By combining the eccentric swinging and ultrasonic vibration shaking of the sample inside the test tube, the shaking effect of the device on the sample in the later stage can be improved.
