[0011] Beneficial Effects
[0012] In the utility model, the sample box is lifted together with the placement tray inside, and the sample on the sample tray can be lifted to a position where the detector can extract it. After the personnel put the required samples in the specified positions of the placement tray in turn, a specific reagent is added to dilute the liquid, and the placement tray can be rotated together with the sample to complete the mixing in combination with the self-rotation of the placement tray, and finally it is lifted to the specified position to extract the sample into the detector through the sampling tube to wait for detection. At the same time, since the sample box can be lifted and lowered, the position of the sampling tube in the sample tube can be controlled according to the situation, and the supernatant after the liquid dilution and mixing can be effectively extracted, so as to prevent the mixed precipitate from being extracted into the instrument and causing inaccurate detection. In addition, combined with the rotation of the placement tray, multiple groups of samples can be extracted simultaneously in turn, thereby improving the efficiency of detection and realizing automation.

At this time, the sample tube can be rotated and mixed in coordination with the rotation of the sample tray, and the opening of the sample tube can be sealed by the sealing cover to prevent a large amount of liquid from flowing out during mixing. At the same time, as the sample tray rotates, the liquid for dilution and mixing can be extracted from the hose to the corresponding sample. After completion, the sealing cover can be returned to its original position, so that the sample box can be normally raised to the extraction position, and the operation is simple and convenient.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:
[0024] Embodiment 1:
[0025] Reference Figure 1-5 The liquid component detector based on precision analysis includes a detector 1. The detector 1 is a liquid mass spectrometer, which can detect organic matter, inorganic matter, medicine and other components in the liquid. A sampling tube 2 is connected to the top of the detector 1. A sample box 6 is provided on the side of the detector 1. A placement tray 7 is movably connected to the sample box 6. The sample box 6 is the outer shell of the placement tray 7. The liquid sample to be tested is placed in the placement position of the placement tray 7. After waiting for dilution and mixing, it can be extracted by the sampling tube 2 of the detector 1 and wait for the detection to be completed. Due to the different concentrations of different liquids, for example, the liquid samples of oral liquids are relatively concentrated. If they are directly put into the detector 1 for detection, they may exceed the detection range or cause instrument failure. Therefore, it is necessary to dilute the sample to an appropriate concentration range for detection. The detector 1 includes a power system, a sampling system, a separation system, a detection system and a data processing system. The detector of the detection system can convert the signals of each component in the sample into electrical signals and finally perform data analysis to obtain the results.
[0026] A column 3 is provided on the side of the detector 1, and a movable bracket 5 is connected to the cavity of the column 3, and the movable bracket 5 is fixed to the surface of the sample box 6. A screw 4 is provided in the cavity of the column 3, and the movable end of the movable bracket 5 is sleeved on the surface of the screw 4, and the movable end of the movable bracket 5 is threadedly connected to the surface of the screw 4. The sample box 6 is connected to the screw 4 in the column 3 by the movable bracket 5 and is threadedly connected to it. After adding components such as a motor to the screw 4, it can be rotated. When the screw 4 rotates, the movable bracket 5 can move linearly along the surface of the screw 4, and the shape of the cavity in the column 3 is used to limit the movable bracket 5 so that it can only be lifted and lowered linearly.
[0027] A rotating rod 13 is fixed to the bottom of the placement tray 7, and the rotating rod 13 is rotatably connected to the interface at the bottom of the sample box 6. A driving component 14 is provided at the bottom of the sample box 6. A placement groove is arranged in a circular array on the top surface of the placement tray 7. The placement tray 7 is connected to the interface at the bottom of the sample box through the rotating rod 13, and the two are rotatably connected. A driving component 14 is added to the rotating rod 13 to make the rotating rod 13 rotate together with the placement tray 7 in the sample box 6. Further explanation: the driving component 14 is composed of a motor, a bevel gear and other components. The bevel gear on the surface of the rotating rod 13 is meshed with the bevel gear at the rotating end of the motor. When the motor is working, the rotating rod 13 can be rotated by the bevel gear transmission to complete the rotation of the placement tray 7. The rotation of the placement tray 7 can mix the sample added with a specific liquid to complete the dilution and the precipitation of the precipitate.
[0028] The sample box 6 can be raised and lowered together with the placement plate 7. After the dilution and mixing are completed, the sample can be raised to the specified sampling height for extraction. Since the sample will produce sediment after dilution and mixing, the free rise can accurately control the supernatant of the sample to be extracted, thereby improving the accuracy of the detection and analysis and making the detection result more precise. The mixed sample rises to the extraction height, and one group of samples is aligned with the sampling tube 2. After waiting for the sample here to be extracted, it is lowered a certain distance so that the placement plate 7 can rotate normally. After rotating a fixed angle, the next group of samples is aligned with the sampling tube 2 and then raised to extract the next group of samples. The operation is carried out in sequence and the detection result of the detector 1 can be waited.
[0029] Embodiment 2:
[0030] Reference Figure 1-5 A sealing cover 9 is provided on one side of the sample box 6, a turntable 10 is connected to one side of the sealing cover 9, a hose 11 is connected to the top interface of the sealing cover 9, and the sealing cover 9 is movably connected to the turntable 10. When adding diluent, the sample box 6 is lowered to the lowest end in advance, and the sealing cover 9 is rotated 90°. At this time, the position of the placement plate 7 is adjusted to align the sample with the through hole on the turntable 10, so that the sample tube rises and contacts the turntable 10, and a water pump and other components are added to send the required added liquid into the hose 11, and the liquid in the group is sent to the sample tube through the hose 11 The placing plate 7 is rotated in sequence to pass the sample tubes through the hose 11 of the sealing tube in sequence, and the liquid addition can be completed. It is necessary to explain that the turntable 10 can rotate in the interface of the sealing cover 9, and the two do not affect each other. At the same time, the interface of the hose 11 of the sealing cover 9 runs through the sealing cover 9, ensuring that when the turntable 10 rotates, the two interfaces will overlap. At the same time, because the top of the sample tube is against the turntable 10, the turntable 10 can be rotated together when the placing plate 7 is rotated. When mixing is required, it only needs to be rotated. When the sample is rotated and mixed, the sealing cover 9 can be used to prevent the sample from flowing out
[0031] One end of the sealing cover 9 is connected to the support column 8, and the connecting end at the bottom of the support column 8 is bolted to the column 3 and the side of the detector 1 respectively. One end of the sealing cover 9 is axially connected to the connection at the top of the support column 8. Drive shells 12 are respectively provided on both sides of the support column 8. Further explanation: one end of the sealing cover 9 is axially connected to the connecting end at the top of the support column 8, and drive shells 12 are added on both sides of the support column 8. The interior of the drive shell 12 includes components such as a motor and a gear set, which are used to drive the connecting shaft at the top of the support column 8 to make the sealing cover 9 complete the rotation, thereby ensuring that the sealing cover 9 returns to its original position after dilution and mixing without affecting the lifting and lowering of the sample box 6.
