Description

Technical Field

[0001] This utility model relates to the field of spectrometer sample tray technology, and in particular to an X-ray fluorescence spectrometer sample tray. Background Technology

[0002] X-ray fluorescence spectrometers, as core equipment in the field of materials composition analysis, are widely used in industries such as geological exploration, metallurgical manufacturing, and environmental monitoring. In their testing processes, the sample tray, as a key component for supporting and securing samples, directly affects the accuracy and efficiency of the test results. With the increasing diversity of analytical sample types, higher demands are placed on the versatility and stability of the sample tray, necessitating structural innovation to improve its overall performance.

[0003] Currently, most X-ray fluorescence spectrometer sample trays on the market employ fixed or semi-fixed mechanical structures. Fixed trays are typically integrally molded, with a fixed sample slot size and shape, relying on the friction between the sample and the slot wall or simple clips for positioning. Semi-fixed trays, on the other hand, use bolts, nuts, or other connectors to clamp and fix the sample, or employ pre-set sample slots of various sizes to accommodate different samples. These traditional structures rely on standardized sample dimensions and achieve fixation through mechanical contact. Their technical principles are primarily based on static constraints and rigid positioning, making it difficult to meet the testing needs of complex-shaped and non-standard-sized samples.

[0004] However, existing technologies lack adaptive adjustment capabilities in their tray structures, making it difficult to accommodate samples of different sizes. This leads to unstable fixation issues in actual testing when the sample size does not match the tray's preset specifications. For example, for irregular blocky samples or small powder tablets, traditional trays either fail to provide effective clamping or cause sample deformation due to excessive compression, thus affecting the accuracy of X-ray excitation and the reliability of detection results. This significantly limits the application of spectrometers in diverse sample analysis scenarios. To address these issues, a sample tray for X-ray fluorescence spectrometers is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sample tray for an X-ray fluorescence spectrometer, aiming to improve the problems of sample trays in the prior art being difficult to adapt to samples of different sizes and having unstable fixation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An X-ray fluorescence spectrometer sample tray includes a tray body, a fixed shaft fixedly connected inside the tray body, a clamping assembly disposed on the upper surface of the tray body, and a fixing assembly disposed inside the fixed shaft.

[0008] The clamping assembly includes a clamping plate and a rubber pad. The sidewall of the clamping plate is slidably connected to the upper surface of the pallet body, and the sidewall of the rubber pad is fixedly connected to the sidewall of the clamping plate. A fixing frame is fixedly connected to the upper surface of the pallet body, and a fixing sleeve is fixedly connected to the sidewall of the fixing frame.

[0011] As a further description of the above technical solution:

[0012] The fixing component includes a locking block, the sidewall of which is slidably connected inside the fixing shaft, and a handle is fixedly connected to the upper surface of the tray body.

[0013] As a further description of the above technical solution:

[0014] A sliding rod is slidably connected inside the fixed shaft, and a pull ring is provided inside the sliding rod.

[0015] As a further description of the above technical solution:

[0016] An installation sleeve is fixedly connected inside the fixed shaft, and the side wall of the sliding rod is slidably connected inside the installation sleeve. A fixing ring is fixedly connected to the side wall of the sliding rod.

[0024] 1. In this utility model, the combination of spring 1, clamping plate, slide rod and rubber pad allows the clamping plate to be manually adjusted according to the sample size, and tightly clamps samples of different sizes under the action of spring tension, thereby achieving the effect of fixing samples of multiple sizes.

This solves the problem of cumbersome and time-consuming installation and disassembly of existing sample trays. The above structure improves the efficiency of instrument maintenance and tray replacement. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an X-ray fluorescence spectrometer sample tray, comprising a tray body 1, which carries the sample and various components. A fixing shaft 2 is fixedly connected inside the tray body 1. A clamping component is provided on the upper surface of the tray body 1 to fix samples of different sizes and shapes, ensuring that the sample is stable in position during the detection process. A fixing component is provided inside the fixing shaft 2 to enable quick installation and disassembly between the tray and the instrument, improving the efficiency of instrument maintenance and tray replacement.

[0035] The clamping assembly includes a clamping plate 6 and a rubber pad 7. The clamping plate 6 is used to clamp the sample. By moving and changing its position, it can adapt to samples of different sizes, achieving a flexible adjustment of the clamping range. The sidewall of the rubber pad 7 is fixedly connected to the sidewall of the clamping plate 6. The rubber pad 7 is made of elastic rubber and its function is to increase the friction with the sample surface, prevent the sample from slipping, and avoid direct contact between the clamping plate 6 and the sample, which could cause damage. The sidewall of the clamping plate 6 is slidably connected to the upper surface of the tray body 1. A fixing frame 3 is fixedly connected to the upper surface of the tray body 1. A fixing sleeve 4 is fixedly connected to the sidewall of the fixing frame 3. A sliding rod 5 is slidably connected inside the fixing sleeve 4. The sliding rod 5 cooperates with the fixing sleeve 4 to perform linear sliding motion, achieving the effect of guiding the clamping plate 6 to move smoothly and ensuring that the clamping plate 6 will not shift during movement. The side wall of plate 6 is fixedly connected to one end of slide rod 5. The side wall of clamping plate 6 is fixedly connected to mounting base 9. Spring 8 is provided on the side wall of clamping plate 6. One end of spring 8 is fixedly connected to the side wall of fixing frame 3, and the other end of spring 8 is fixedly connected to the side wall of mounting base 9. Spring 8 generates elastic force in the tensile or compressed state, which cooperates with clamping plate 6. After clamping the sample, the elastic force of spring 8 can make clamping plate 6 tightly clamp the sample, realizing the effect of adaptive adjustment of clamping force. The bottom of clamping plate 6 is fixedly connected to fixing block 10. The side wall of fixing block 10 is slidably connected to the inside of tray body 1. Fixing block 10 cooperates with tray body 1 to perform sliding limit movement, which further ensures the stability and straightness of clamping plate 6 movement and prevents clamping plate 6 from shaking or flipping during movement.

[0036] Reference Figures 4-5The fixing component includes a locking block 18, which engages with a slot on the X-ray fluorescence spectrometer main unit to quickly lock the tray to the instrument, achieving a stable installation of the tray. The side wall of the locking block 18 is slidably connected inside the fixed shaft 2, allowing it to extend and retract within the fixed shaft 2 to engage and disengage from the slot. A handle 20 is fixedly connected to the upper surface of the tray body 1, facilitating the user's handling, installation, and disassembly of the tray, improving operational convenience. A sliding rod 11 is slidably connected inside the fixed shaft 2, transmitting external force. The sliding rod 11 contains a pull mechanism. Ring 12, the pull ring 12 is used by the user to pull the sliding rod 11, facilitating the control of the movement of the sliding rod 11. A mounting sleeve 13 is fixedly connected inside the fixed shaft 2. The side wall of the sliding rod 11 is slidably connected inside the mounting sleeve 13. The sliding rod 11 and the mounting sleeve 13 cooperate to perform linear sliding motion, achieving precise control of the sliding rod 11's movement trajectory. A fixing ring 15 is fixedly connected to the side wall of the sliding rod 11. A second spring 14 is sleeved on the side wall of the sliding rod 11. One end of the second spring 14 is fixedly connected inside the fixed shaft 2, and the other end is fixedly connected to the side wall of the fixing ring 15. The second spring 14 is used for lifting... The elastic force pushes the locking block 18 out and into the slot during tray installation. During disassembly, it is compressed and stores energy, which, in conjunction with the sliding rod 11, achieves the effect of automatic pop-out and retraction of the locking block 18. A fixing rod 17 is fixedly connected to the side wall of the mounting sleeve 13. The locking block 18 is internally slidably connected to the side wall of the fixing rod 17. The locking block 18 and the fixing rod 17 cooperate to perform linear sliding motion, thus limiting the direction of movement of the locking block 18 and ensuring that the locking block 18 accurately enters or exits the slot. A pull bar 16 is rotatably connected to the side wall of the locking block 18. One end of the pull bar 16 is rotatably connected to the side wall of the fixing ring 15. The pull bar 16 is used to control the sliding... The linear motion of the moving rod 11 is converted into the linear sliding of the locking block 18, realizing the motion transmission between the two. The pull bar 16 works in conjunction with the fixed ring 15 and the locking block 18 to achieve the effect of synchronously controlling the extension and retraction of the locking block 18. The bottom of the locking block 18 is fixedly connected to the limit block 19. The side wall of the limit block 19 is slidably connected inside the fixed shaft 2. The limit block 19 is used to limit the movement range of the locking block 18, prevent the locking block 18 from detaching from the fixed shaft 2, and further enhance the stability of the locking block 18 when it moves. The limit block 19 works in conjunction with the fixed shaft 2 to perform the limiting movement, thus ensuring the reliable operation of the locking block 18.

[0037] Working Principle: When fixing the sample, the user first places the sample between the clamping plates 6. When the clamping plates 6 contact the sample, a pushing force is applied, causing the rubber pad 7 to tightly adhere to the sample surface, thus initially fixing the sample. At this time, spring 8 is stretched, generating a reverse pulling force. This pulling force acts on the clamping plates 6 through the mounting base 9, causing the clamping plates 6 to tightly clamp the sample. The rubber pad 7 not only increases the friction between the sample and the clamping plate, preventing slippage, but also avoids direct contact between the clamping plates 6 and the sample, thus achieving stable clamping of the sample and ensuring the sample position is fixed during X-ray fluorescence spectrometry detection, guaranteeing the accuracy of the detection results. When installing the tray onto the X-ray fluorescence spectrometer, the fixing shaft 2 mates with the corresponding mounting structure on the instrument. At this time, the locking block 18, under the elastic force of spring 14, extends outward and locks into the instrument's slot, achieving fixed installation of the tray. In the initial state, spring 14 is in a compressed state. The movable fixed ring 15 and the sliding rod 11 move outward. The sliding rod 11 pulls the locking block 18 outward through the pull bar 16. The locking block 18 slides on the fixed rod 17 until the locking block 18 is fully extended out of the fixed shaft 2 and locked into the instrument's slot. At the same time, the limiting block 19 slides inside the fixed shaft 2 to limit the movement direction of the locking block 18, ensuring that the locking block 18 is accurately locked into the slot, so that the tray is securely installed on the instrument. When the tray needs to be removed, the user pulls the pull ring 12. The pull ring 12 drives the sliding rod 11 to slide inside the mounting sleeve 13, overcoming the elastic force of the second spring 14 and moving into the fixed shaft 2. When the sliding rod 11 moves, it pulls the locking block 18 into the fixed shaft 2 through the pull bar 16, so that the locking block 18 is removed from the instrument's slot. At this time, the second spring 14 is compressed. When the locking block 18 is completely removed from the slot, the user can remove the tray body 1 from the instrument through the handle 20 to complete the disassembly operation, which is convenient for cleaning, maintenance or replacement of different sizes of trays.
