[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] This invention provides an atomic fluorescence spectrometer, such as... Figures 1 to 4 As shown, the instrument includes: a frame 1, a worktable 2, and a positioning assembly. The frame 1 supports the atomic fluorescence spectrometer and houses optical equipment, detection equipment, gas control equipment, and data processing and control equipment. A cover plate 12 is hinged to the top of the frame 1, and an atomization device is housed inside the cover plate 12. The worktable 2 houses an excitation light source and is connected to the frame 1 for placing the sample to be tested. The positioning assembly includes a telescopic component 3, a movable component 4, a guide component 5, a compression component 6, and a rubber component 7. The telescopic component 3 can be an electrically operated telescopic rod, which is formed by the movable insertion of two rod-shaped objects filled with hydraulic oil. The extension and retraction of the two rod-shaped objects are achieved by the injection and extraction of hydraulic oil. This is existing technology and will not be described in detail here. The telescopic component 3 is located on the worktable. The movable end of the telescopic component 3 is driven to connect with the movable component 4. The movable component 4 can be a movable block. There are two movable components 4 on the worktable 2, located on both sides of the excitation light source device. The movable component 4 is movably set on the worktable 2. The guide component 5 can be a guide block. The guide component 5 is connected to the movable component 4 and is slidably set on the worktable 2. The extrusion component 6 can be an extrusion plate. The shape of the extrusion component 6 is semi-circular. The extrusion component 6 is connected to the movable component 4. The rubber component 7 can be a rubber sheet. The rubber component 7 is bonded to the extrusion component 6. The telescopic component 3 drives the extrusion component 6 to move in the vertical direction through the movable component 4. Multiple extrusion components 6 are evenly spaced on the movable component 4. The extrusion component 6 and the rubber component 7 are set one-to-one. The rubber component 7 is located on the outer side of the movable component 4 and is attached to the worktable 2.

[0025] By using positioning components, the sample to be tested can be squeezed and fixed, thereby effectively limiting the sample and preventing positional displacement caused by external factors during the testing process, thus ensuring the accuracy of the atomic fluorescence spectrometer detection results.

[0026] In use, when a sample needs to be tested, the sample is placed on the worktable 2 and then pushed laterally so that it reaches above the excitation light source device. At this time, the sample is located between two movable parts 4. Then, the telescopic part 3 is activated. The movable end of the telescopic part 3 drives the movable part 4 to move downward. The movement of the movable part 4 drives the guide part 5 and the extrusion part 6 to move synchronously. The movable part 4 slides inside the worktable 2 guided by the guide part 5 to ensure a stable movement trajectory. The movement of the extrusion part 6 drives the rubber part 7 to move synchronously. As the movable part 4 moves, the multiple semi-circular extrusion parts 6 on the movable part 4 press down vertically, causing the rubber part 7 at the bottom of the extrusion part 6 to keep in contact with the sample to be tested.

[0027] Specifically, a workbench 2 is fixedly connected to the top of the frame 1. Two telescopic components 3 are provided inside the workbench 2. A movable component 4 is fixedly connected to the movable end of the telescopic component 3. The outer surface of the movable component 4 is movably connected to the inside of the workbench 2. Guide components 5 are fixedly connected to both ends of the movable component 4. The outer surface of the guide component 5 is slidably connected to the inside of the workbench 2. Multiple extrusion components 6 are fixedly connected to the outer surface of the guide component 5. A rubber component 7 is glued to the bottom end of the extrusion component 6.

[0028] To improve the stability of atomic fluorescence spectrometers, such as Figures 1 to 4 As shown, it also includes a protective assembly, which includes a first connector 8, a movable arm 9, a second connector 10, and a suction cup 11. The first connector 8 can be a connecting plate and is connected to the frame 1. The movable arm 9 is movably mounted on the first connector 8. The second connector 10 can be a connecting plate and is movably mounted on the movable arm 9. There are two suction cups 11. The bottom of the suction cup 11 is lower than the bottom of the frame 1. The suction cup 11 is mounted on the second connector 10. The movable arm 9 drives the suction cup 11 to move through the second connector 10. There are two first connectors 8 on the frame 1. The two first connectors 8 are located at both ends of the frame 1. The suction cup 11 is located on the outside of the frame 1 and below the frame 1.

[0029] Protective components can effectively improve the stability of atomic fluorescence spectrometers, preventing instrument displacement or tipping when subjected to external impacts, thus preventing damage to the atomic fluorescence spectrometer and effectively extending its service life.

[0030] When using the atomic fluorescence spectrometer, first place the atomic fluorescence spectrometer on the table, then raise the suction cups 11 located at both ends of the frame 1. The suction cups 11 drive the movable arm 9 to rise synchronously through the connector 2 10, so that one end of the movable arm 9 rotates around the connector 1 8, keeping the movable arm 9 in an inclined state. Then, the suction cups 11 are attracted to the table. When subjected to external force, the attraction force of the suction cups 11 prevents the instrument from shifting or tipping over.

[0031] Specifically, both ends of the frame 1 are fixedly connected to connector 1 8. One end of connector 1 8 is movably connected to a movable arm 9 via a pin. One end of movable arm 9 is movably connected to connector 2 10 via a pin. The bottom end of connector 2 10 is fixedly connected to a suction cup 11.

[0032] Working principle: In actual use, when the atomic fluorescence spectrometer needs to be used, the atomic fluorescence spectrometer is first placed on the table. Then, the suction cups 11 located at both ends of the frame 1 are raised. The suction cups 11 drive the movable arm 9 to be raised synchronously through the connector 2 10, so that one end of the movable arm 9 rotates around the connector 1 8, keeping the movable arm 9 in an inclined state. Then, the suction cups 11 are attracted to the table. When subjected to external force collision, the suction force of the suction cups 11 prevents the instrument from shifting or tipping over, which can effectively improve the stability of the atomic fluorescence spectrometer, avoid the instrument shifting or tipping over when subjected to external force collision, prevent the atomic fluorescence spectrometer from being damaged by collision, and thus effectively extend the service life of the atomic fluorescence spectrometer.

[0033] Then, when the sample to be tested needs to be tested, the sample is placed on the worktable 2 and then pushed laterally so that it reaches above the excitation light source device. At this time, the sample is located between the two movable parts 4. Then, the telescopic part 3 is activated. The movable end of the telescopic part 3 drives the movable part 4 to move downward. The movement of the movable part 4 drives the guide part 5 and the extrusion part 6 to move synchronously. The movable part 4 slides inside the worktable 2 guided by the guide part 5 to ensure a stable movement trajectory. The movement of the extrusion part 6 drives the rubber part 7 to move synchronously. As the movable part 4 moves, the multiple semi-circular extrusion parts 6 on the movable part 4 press down vertically, causing the rubber part 7 at the bottom of the extrusion part 6 to keep in contact with the sample to be tested. This can achieve the compression and fixation of the sample to be tested, thereby effectively limiting the position of the sample to be tested and avoiding positional deviation caused by external factors during the testing process, thus ensuring the accuracy of the atomic fluorescence spectrometer detection results.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
