[0001] This utility model belongs to the field of sample stage technology, specifically relating to an adjustable Raman spectrometer sample stage. Background Technology
[0002] A laser Raman spectrometer is a comprehensive measurement system integrating laser spectroscopy, precision mechanics, and microelectronics. Its final result is a spectrum showing the intensity of scattered light with a specific polarization state in a given direction, distributed as a function of frequency. Its main applications are the analysis of the molecular composition, structure, and relative content of various solid, liquid, and gaseous substances, enabling the identification and characterization of these substances. During operation, a sample stage is required to receive the sample.
[0003] Existing Raman spectrometer sample stages use a system of overall lifting or tilting, which does not allow for independent adjustment of individual corners of the stage. This makes it difficult to achieve ideal placement results when dealing with irregularly shaped samples or samples with specific angle requirements. Furthermore, adjusting the height and tilt angle of the sample stage is not flexible or convenient, and the operation process is cumbersome, making it difficult to quickly and accurately achieve the desired sample placement. Therefore, an adjustable Raman spectrometer sample stage is needed to help solve this problem. Utility Model Content

This adjustable Raman spectrometer sample stage enables precise adjustment of the height of a single corner of the sample stage body. By adjusting four adjustment components, it can meet various complex sample placement angle requirements, expand the application range of the Raman spectrometer, and adapt to the detection of samples with different shapes and properties.
[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides an adjustable Raman spectrometer sample stage, which includes a mounting platform. The mounting platform has a cavity inside, and a slide is slidably disposed in the cavity. A top seat is installed at the top of the slide, and a limiting groove is opened in the middle section of the side of the top seat. A fixing hole is drilled in the limiting groove, and a threaded hole is drilled at the outer edge of the mounting platform. A fixing bolt that mates with the fixing hole is threaded onto the threaded hole. The top of the top seat is equipped with a sample stage body for receiving, and each of the four corners of the sample stage body is provided with an adjustment cavity. Each of the four corners of the top of the top seat is equipped with an adjustment component, and the top of the adjustment component is installed in the adjustment cavity.
[0006] Furthermore, the adjustment assembly includes a base rotatably mounted on the top of the top seat, a lead screw fixed at the center of the top of the base, a sleeve sleeved on the lead screw, the sleeve and the lead screw being threadedly engaged, and a collar nested at the top of the sleeve, the collar being hinged in the adjustment cavity.
[0007] Furthermore, a protruding rod is provided on the outer side of the base, and several protruding rods are symmetrically arranged on the outer side of the base.
[0008] Furthermore, a horizontal bubble meter is embedded at the outer edge of the top of the sample stage body, and the horizontal bubble meter is arranged diagonally on the sample stage body.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features an adjustment component that allows for more flexible and convenient adjustment of the height and tilt angle of the sample stage.

Detailed Implementation
[0016] 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.
[0017] This specific embodiment is an adjustable Raman spectrometer sample stage, such as... Figures 1-4 As shown, the adjustable Raman spectrometer sample stage includes a mounting stage 1. The mounting stage 1 has a cavity inside, and a slide stage 2 is slidably arranged inside the cavity. A top seat 3 is installed at the top of the slide stage 2. A limiting groove 32 is opened in the middle section of the side of the top seat 3. A limiting block 31 is protruding on the side of the cavity of the mounting stage 1. The limiting block 31 is slidably arranged in the limiting groove 32. A fixing hole 4 is drilled in the limiting groove 32. A threaded hole 7 is drilled at the outer edge of the mounting stage 1. A fixing bolt 5 is threaded on the threaded hole 7 and fixed to the fixing hole 4. A positioning pin 6 is protruding on the fixing bolt 5. The positioning pin 6 is inserted into the fixing hole 4. Several fixing holes 4 are arranged at equal intervals from top to bottom on the limiting groove 32.
[0018] The cooperation between the limiting block 31, the limiting groove 32, and the fixing bolt 5, as well as the cooperation between the limiting block 31 and the limiting groove 32 and the insertion and fixing of the fixing bolt 5 and the fixing hole 4, ensures that the position of the sample stage body 9 is stable after adjustment and will not be displaced during the experiment, thereby improving the accuracy and reliability of the experiment.
[0019] A scale plate 8 is vertically embedded on the outer side of the slide 2. The scale plate 8 is engraved with scale lines. By sliding the slide 2 in the cavity of the mounting platform 1 and setting the scale plate 8, the horizontal position of the sample stage body 9 can be precisely adjusted to meet the requirements of different experiments for sample position.
[0020] The top of the top seat 3 is equipped with a sample stage body 9 for receiving. Each of the four corners of the sample stage body 9 has an adjustment cavity. Each of the four corners of the top of the top seat 3 is equipped with an adjustment component 10. The top of the adjustment component 10 is installed in the adjustment cavity. The adjustment component 10 includes a base 14 that is rotatably embedded in the top of the top of the top seat 3. A lead screw 13 is fixed at the center of the top of the base 14. A sleeve 11 is sleeved on the lead screw 13. The sleeve 11 and the lead screw 13 are threaded together. A collar 12 is nested at the top of the sleeve 11. The collar 12 is hinged in the adjustment cavity.
[0021] The adjustable components 10 make the height and tilt angle adjustment of the sample stage body 9 more flexible and convenient. By rotating the base 14, the lead screw 13 is rotated, which in turn moves the sleeve 11 up and down, thus realizing the precise adjustment of the height of a single corner of the sample stage body 9. By adjusting the four adjustable components 10 respectively, various complex sample placement angle requirements can be met, expanding the application range of the Raman spectrometer and enabling it to adapt to the detection of samples with different shapes and properties.
[0022] Furthermore, a protruding rod 141 is provided on the outer side of the base 14. Several protruding rods 141 are symmetrically arranged on the outer side of the base 14. Through the provided protruding rods 141, the base 14 can be easily rotated during operation, thus avoiding problems such as inconvenience in adjusting the adjustment component 10.
[0023] Furthermore, a horizontal bubble level 15 is embedded and installed at the outer edge of the top of the sample stage body 9. The horizontal bubble level 15 is diagonally arranged on the sample stage body 9. The diagonal arrangement of the horizontal bubble level 15 on the sample stage body 9 can more accurately detect the horizontal state of the sample stage body 9. When adjusting the height and tilt angle of the sample stage body 9, it is possible to understand in a timely and intuitive manner whether the sample stage body 9 is horizontal, which is convenient for operators to make adjustments to ensure that the sample is in a horizontal state. This improves the accuracy and stability of Raman spectroscopy detection and reduces detection errors caused by uneven sample placement.
[0024] Working principle: When it is necessary to adjust the vertical position of the sample stage body 9, adjust the slide 2 to the specified height, and at the same time observe the scale lines on the scale plate 8 vertically embedded on the outer side of the slide 2. The sliding distance can be precisely controlled. After determining the position, screw the fixing bolt 5 into the threaded hole 7 on the outer edge of the mounting platform 1, so that the positioning pin 6 on the fixing bolt 5 and the corresponding fixing hole 4 on the limiting groove 32 of the top seat 3 are engaged and plugged in, thereby fixing the slide 2 in the current position and realizing the adjustment and fixation of the horizontal position of the sample stage body 9.
[0025] When it is necessary to adjust the tilt angle of the sample stage body 9, rotate the base 14. The base 14 drives the lead screw 13 to rotate. Since the sleeve 11 is threadedly engaged with the lead screw 13 and the collar 12 is hinged to the sample stage body 9, the rotation of the lead screw 13 will cause the sleeve 11 to move up and down on the lead screw 13, thereby causing one corner of the sample stage body 9 to rise or fall. By adjusting the four adjustment components 10 respectively, the height and tilt angle of the sample stage body 9 can be adjusted.
[0026] A horizontal bubble level 15 is embedded in the outer edge of the top of the sample stage body 9, and the horizontal bubble level 15 is diagonally arranged on the sample stage body 9. By observing the position of the bubbles in the horizontal bubble level 15, it can be determined whether the sample stage body 9 is in a horizontal state. When the bubbles in both horizontal bubble level 15 are in the middle position, it indicates that the sample stage body 9 is in a horizontal state.
[0027] All technical features in this embodiment can be freely combined according to actual needs.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
