Description

Technical Field

[0001] This utility model relates to the field of sample tray technology, and more specifically, to a sample tray structure for an atomic fluorescence spectrometer. Background Technology

[0002] The sample tray of an atomic fluorescence spectrometer is the core component that holds sample vials and enables automated sample introduction. It is typically a circular or square tray made of corrosion-resistant materials and can hold dozens to hundreds of sample vials. Its position varies depending on the model; some are located on the left side of the instrument, while others are designed to be on the front or right. Driven by a stepper motor, it rotates and, in conjunction with a photoelectric sensor, precisely positions the sample. It often integrates functions such as a cleaning station and temperature control module, providing support for automated analysis of batch samples. The working principle of the atomic fluorescence spectrometer sample tray is as follows: the stepper motor drives the tray to rotate, the photoelectric sensor identifies the positioning hole to determine the sample position, and the target sample vial is moved to below the injection needle. After the injection needle completes sampling, the tray drives the sample vial away and controls the injection needle to insert into the cleaning station for cleaning to prevent cross-contamination. The entire process is automatically controlled by a pre-set software sequence, enabling sequential analysis of standards, samples, and quality control samples, significantly improving detection efficiency and repeatability. Since different samples have different sample tube sizes, it is necessary to perform lifting and lowering adjustments.

[0003] In related technologies, during the use of the sample tray in an atomic fluorescence spectrometer, sample tubes of different sizes are typically accommodated and supported through a through-hole at the top of the sample tray.

[0004] However, in the current use of atomic fluorescence spectrometer sample trays, due to the fixed height of the tray, it is difficult to accommodate taller sample tubes of different sizes and heights, which affects the adaptability and flexibility of the sample tray. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a sample tray structure for an atomic fluorescence spectrometer, including a base 1 and a tray lifting mechanism. A tray cavity 2 is installed on the left side of the top of the base 1, and a tray frame 3 is installed at the bottom of the inner wall of the tray cavity 2. This allows the base 1 to support external sample tubes while enabling users to adjust the height according to the actual usage height requirements of the external sample tubes. This avoids the situation where the support height of the sample tubes is difficult to adjust when the base 1 is in use, thus improving the adaptability and flexibility of the base 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the disk lifting mechanism includes a support disk 4, which is movably connected inside the disk frame 3. A lifting column 5 is movably connected to the top of the support disk 4, and a top disk 6 is movably connected to the top of the outer side of the lifting column 5. A base disk 7 is movably connected to the bottom of the outer side of the lifting column 5. A lifting connection mechanism is fixedly connected to the top of the support disk 4. According to the actual placement height requirement of the external sample tube, the lifting column 5 can be moved up and down by hand, which can drive the top disk 6 to move upward, thereby adjusting the support height of the top disk 6 for the external sample tube. The lifting connection mechanism includes a connecting column. 8. Connecting groove 9 and connecting ring 10: The connecting column 8 is fixedly connected to the top of the support plate 4. The connecting groove 9 is opened at the top of the connecting column 8. The bottom of the lifting column 5 is located inside the connecting groove 9. The connecting ring 10 is fixedly connected to the surface of the lifting column 5 and the connecting column 8 respectively. This allows for lifting and lowering connection between the lifting column 5 and the support plate 4, and provides support connection between the top plate 6 and the bottom plate 7. This prevents the lifting column 5 from shifting from the support plate 4 during use, or the top plate 6 and the bottom plate 7 from falling down. Therefore, it improves the working stability of the lifting column 5, the top plate 6, and the bottom plate 7.

[0032] Reference Figures 2-4In a preferred embodiment, a screw groove 11 is provided at the bottom of the lifting column 5, and a stud 12 is threadedly connected inside the screw groove 11. The bottom of the stud 12 is fixedly connected to the top of the support plate 4, which provides a medium for the user to lift the lifting column 5, avoiding the situation where the lifting column 5 is difficult to lift during use, thus improving the lifting effect of the lifting column 5. Magnetic strips 13 are embedded and connected to both sides of the inner wall of the connecting groove 9, and a magnetic ring 14 that is magnetically connected to the magnetic strips 13 is embedded and connected to the bottom of the outer side of the lifting column 5, which can perform magnetic positioning between the lifting column 5 and the connecting column 8, avoiding the situation where the lifting column 5 is easily rotated during use, thus improving the working stability of the lifting column 5.

[0033] Reference Figures 2-4 In a preferred embodiment, a lifting cylinder 15 located outside the connecting column 8 is fixedly connected to the outer side of the top of the chassis 7. A lifting rod 16 is movably connected inside the lifting cylinder 15. The top of the lifting rod 16 is fixedly connected to the bottom of the top plate 6. This allows for lifting and connecting the top plate 6 and the chassis 7 to prevent displacement, thus improving the connection effect between the chassis 7 and the top plate 6. A turntable 17 is movably connected to the top of the lifting column 5. A rotating frame 18 is fixedly connected to the top of the turntable 17, providing the user with an operating medium to rotate the lifting column 5. This prevents the lifting column 5 from being difficult to rotate during use, thus improving the ease of operation of the lifting column 5.

[0034] Reference Figures 2-4 In a preferred embodiment, movable openings 19 are provided on both sides of the top of the turntable 17. Movable bolts 20, which are threadedly connected to the lifting column 5, are provided inside the movable openings 19. This allows for the connection between the turntable 17 and the lifting column 5 to prevent separation, thus improving the connection effect between the turntable 17 and the lifting column 5. Stable seats 21 are fixedly connected to both sides of the turntable 17. Stable openings 22 are provided on both sides of the top of the top plate 6 at the bottom of the stable seats 21. The turntable 17 can be used to stagger and stabilize the top plate 6 and the lifting column 5, preventing the lifting column 5 from moving upward and separating during use. This improves the working stability of the top plate 6.

[0035] Specifically, the working process or principle of the sample tray structure of this atomic fluorescence spectrometer is as follows: During use, when it is necessary to adjust the support height between the top tray 6 and the bottom tray 7 according to the external sample tube, the hand-held rotating frame 18 rotates the turntable 17. At this time, the movable bolt 20 moves inside the movable opening 19. When the movable bolt 20 moves to one side inside the movable opening 19, the turntable 17, in conjunction with the movable bolt 20, applies rotational force to the lifting column 5. Simultaneously, the threaded groove 11, in conjunction with the stud 12, provides threaded thrust for the lifting column 5 to move up and down. The bottom of the device moves within the connecting groove 9. The connecting groove 9, in conjunction with the connecting column 8, performs lifting and reinforcing work between the lifting column 5 and the support plate 4. At this time, the stabilizing seat 21 rotates with the turntable 17 and is offset from the stabilizing port 22. The stabilizing seat 21 provides offset locking and stabilizing work between the top plate 6 and the lifting column 5. During this process, the connecting ring 10 provides lifting and supporting connection between the top plate 6 and the lifting column 5. Since the top of the connecting ring 10 is connected to the top plate 6 via plugs, it simultaneously supports the connection between the top plate 6 and the lifting column 5. The top plate 6 is positioned and stabilized. Simultaneously, the lifting rod 16 moves with the top plate 6 inside the lifting cylinder 15, ensuring a stable connection between the top plate 6 and the base plate 7 to prevent misalignment. At this time, the magnetic ring 14 moves with the lifting column 5 inside the connecting groove 9. After the lifting column 5 adjusts the height of the top plate 6 via the screw groove 11, screw 12, and connecting ring 10, the magnetic ring 14, in conjunction with the magnetic strip 13, magnetically positions and stabilizes the lifting column 5 and connecting column 8. Then, external sample tubes can be placed inside the top plate 6 and base plate 7. The top plate 6, in conjunction with the base plate 7 and support plate 4, provides stable support for the external sample tubes inside the placement hole. When the sample tubes inside the top plate 6 need to be removed simultaneously, the hand-held turntable 17 drives the stabilizing seat 21 to rotate and align with the stabilizing port 22. Then, the hand-held top plate 6 is moved upwards, allowing the sample tubes to be moved synchronously through the top plate 6. After the sample tubes are moved out of the base plate 7, the hand-held top plate 6 is flipped over to tilt and detach the multiple sample tubes inside the top plate 6. It is important to ensure that the sample tubes are in a closed state during the tilting and detachment process.

[0036] It should be noted that the push rod 10 and the electromagnet 11 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
