[0002] Fluorescence spectrometers are widely used in materials analysis, biological detection, and other fields. Detection fixtures are used to fix samples, ensuring stable sample position and accurate optical path during detection. However, existing fluorescence spectrometer detection fixtures still have the following problems: they are difficult to adapt to samples of different sizes and shapes, and the clamping operation is cumbersome; the position adjustment after the sample is fixed is inconvenient, affecting detection accuracy; and the clamping stability of the sample is insufficient, making it prone to displacement during detection, leading to deviations in detection results. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a detection fixture for a fluorescence spectrometer, which is equipped with an adjustable fixture assembly and a specially designed fixture base, thus solving the problems of poor fixture adaptability, cumbersome clamping operation, inconvenient position adjustment, and insufficient clamping stability in the prior art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detection fixture for a fluorescence spectrometer, comprising a fixture base, wherein the fixture base is configured with an adjustable fixture assembly.

[0007] The fixture base includes a base body with a through groove between the center of its upper and lower side walls. This through groove provides a channel for the optical path, ensuring that the light from the fluorescence spectrometer can pass smoothly through the sample. A transparent glass plate is fixedly installed on the inner side wall of each of the upper and lower openings of the through groove. The transparent glass plate provides some support for the sample without affecting the optical path transmission. An annular groove is formed in the middle of the outer annular side wall of the base body, and an annular guide rail is fixedly connected to the middle of the inner side wall of the annular groove. The annular groove and the annular guide rail cooperate to provide a basis for the sliding and angle adjustment of the adjustable fixture assembly. Mounting seats are fixedly connected to the lower front and rear ends of the outer annular side wall of the base body. An oblong hole is formed between the upper and lower side walls of the mounting seat. This oblong hole facilitates the installation and fixation of the fixture base on the fluorescence spectrometer detection platform and allows for fine-tuning of the position.

[0008] The adjustable clamp assembly includes two sliders symmetrically slidably connected within an annular groove. The sliders can slide along the annular groove and an annular guide rail to achieve position adjustment. A fixed connection assembly is provided between the two sliders, including arc-shaped connecting rods connecting the front and rear ends of the two sliders respectively. The arc-shaped connecting rods ensure synchronous sliding and stable connection of the two sliders. An L-shaped frame is fixedly connected to one end of each slider, providing support for subsequent component installation. A sliding sleeve is slidably mounted on the outer upper part of the L-shaped frame. A second sliding groove is formed between the two lower side walls of the sliding sleeve for sliding assembly of the L-shaped frame. The sliding sleeve can slide along the L-shaped frame to accommodate samples of different widths. A threaded hole is formed on the side of the sliding sleeve, and the threaded hole communicates with a corresponding... The second sliding groove on one side has a threaded hole with a fastening screw connected internally. The fastening screw is used to lock the position of the sliding sleeve on the L-shaped frame. A spring shaft seat is fixedly installed at the top of the sliding sleeve, and a pressure frame is fixedly installed at the rotating end of the spring shaft seat. The spring shaft seat allows the pressure frame to rotate and has a certain elastic restoring ability, which facilitates quick placement and removal of samples while ensuring clamping force. The pressure frame is a U-shaped frame, and two anti-sliding blocks are fixedly connected to each of the two pressure frames in a symmetrical front-to-back shape at their opposite ends. The anti-sliding blocks increase the friction between the anti-sliding blocks and the sample, improve clamping stability, and prevent the sample from sliding during testing. The two anti-sliding blocks are slidably assembled on the outside of the annular guide rail. The two anti-sliding blocks have a first sliding groove at their opposite ends for sliding assembly with the annular guide rail, ensuring that the blocks slide stably along the annular guide rail.

[0009] As a further improvement of this utility model, the pressure frame is made of elastic alloy material, which combines elasticity and strength, making clamping operation convenient and ensuring stable clamping force.

[0010] As a further improvement of this utility model, the light-transmitting glass plate is a high-transmittance quartz glass plate, which ensures low light transmission loss and improves detection accuracy.

[0011] As a further improvement of this utility model, the gap between the annular guide rail and the slider is less than 0.1mm, which ensures smooth sliding and stable position of the slider and improves adjustment accuracy.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the slider in the adjustable fixture assembly slides along the annular groove and the annular guide rail, and the sliding sleeve slides along the L-shaped frame, so that the two pressing frame positions can be flexibly adjusted to adapt to samples of different sizes and shapes. The clamping operation is simple and the adaptability and operation efficiency of the fixture are greatly improved.

[0014] 2. In this utility model, the adjustable fixture assembly can be stably rotated around the center of the fixture base and its position can be finely adjusted by the cooperation of the annular slide groove and the annular guide rail, thereby improving the clamping accuracy. In addition, the pressure frame, anti-slip block and spring shaft seat cooperate to hold the sample stably, and the sample is not easy to move during the test, thus ensuring the accuracy of the test results.

[0023] Please see Figures 1-4 In this embodiment of the present invention, a detection fixture for a fluorescence spectrometer includes a fixture base 1, and the fixture base 1 is equipped with an adjustable fixture assembly 2.

[0024] The fixture base 1 includes a base body 11. A through groove 12 is provided between the center of the upper and lower side walls of the base body 11. The through groove 12 provides a channel for the optical path, ensuring that the detection light of the fluorescence spectrometer can pass smoothly through the sample. A light-transmitting glass plate 13 is fixedly installed on the inner side wall of the upper and lower openings of the through groove 12. The light-transmitting glass plate 13 can provide a certain support for the sample without affecting the transmission of the optical path. An annular sliding groove 14 is provided in the middle of the annular outer side wall of the base body 11. An annular guide rail 15 is fixedly connected to the middle of the inner side wall of the annular sliding groove 14. The annular sliding groove 14 and the annular guide rail 15 cooperate to provide a basis for the sliding and angle adjustment of the adjustable fixture assembly 2. Mounting seats 16 are fixedly connected to the lower front and rear ends of the outer side wall of the base body 11. An oblong hole 17 is provided between the upper and lower side walls of the mounting seat 16. The oblong hole 17 facilitates the installation and fixation of the fixture base 1 on the detection platform of the fluorescence spectrometer and makes it easy to fine-tune the position.

[0025] The adjustable fixture assembly 2 includes two sliders 21 symmetrically connected within an annular groove 14. The sliders 21 can slide along the annular groove 14 and an annular guide rail 15 to achieve position adjustment. A fixed connection assembly is provided between the two sliders 21, including arc-shaped connecting rods 23 that connect the front and rear ends of the two sliders 21 respectively. The arc-shaped connecting rods 23 ensure synchronous sliding and stable connection of the two sliders 21. An L-shaped frame 24 is fixedly connected to one end of each slider 21, providing support for subsequent component installation. A sliding sleeve 25 is slidably mounted on the outer side of the L-shaped frame 24. A second groove 26 is formed between the two lower side walls of the sliding sleeve 25 for sliding assembly of the L-shaped frame 24. The sliding sleeve 25 can slide along the L-shaped frame 24 to accommodate samples of different widths. A threaded hole 27 is formed on the side of the sliding sleeve 25, connecting to its corresponding side. The second slide groove 26 has a threaded hole 27 with an internal threaded connection to a fastening screw 28, which is used to lock the position of the slide sleeve 25 on the L-shaped frame 24. A spring bearing seat 29 is fixedly installed at the top of the slide sleeve 25, and a pressure frame 210 is fixedly installed at the rotating end of the spring bearing seat 29. The spring bearing seat 29 allows the pressure frame 210 to rotate and has a certain elastic reset capability, which facilitates quick placement and removal of samples while ensuring clamping force. The pressure frame 210 is a U-shaped frame, and two anti-slip blocks 211 are fixedly connected to the two pressure frames 210 in a symmetrical manner at their opposite ends. The anti-slip blocks 211 increase the friction between the anti-slip blocks and the sample, improve the clamping stability, and prevent the sample from sliding during testing. The two sliders 21 are slidably assembled on the outside of the annular guide rail 15. The two sliders 21 have a first slide groove 22 at their opposite ends for the annular guide rail 15 to slide, ensuring that the sliders 21 slide stably along the annular guide rail 15.

[0026] The clamping frame 210 is made of elastic alloy material, which combines elasticity and strength, making it convenient for clamping operations and ensuring stable clamping force.

[0027] The light-transmitting glass plate 13 is a high-transmittance quartz glass plate, which ensures low light transmission loss and improves detection accuracy.

[0028] The clearance between the annular guide rail 15 and the slider 21 is less than 0.1mm, ensuring that the slider 21 slides smoothly and is in a stable position, thus improving the adjustment accuracy.

[0029] The working principle of this utility model is as follows: Using the oblong hole 17 on the mounting base 16, the clamp base 1 is installed onto the fluorescence spectrometer detection platform through bolts and other connecting parts. According to the detection requirements, the position of the clamp base 1 is finely adjusted and the bolts are tightened to fix it. The sample is placed on the top of the upper light-transmitting glass plate 13, and the height of the pressure frame 210 is adjusted by sliding the sliding sleeve 25 so that the pressure frame 210 is adapted to the sample thickness. The fastening screw 28 is tightened to lock the position of the sliding sleeve 25. At this time, the pressure frame 210 can be rotated to adjust the sliding slider 21 so that the pressure frame 210 presses against the edge of the sample. The elasticity of the spring shaft seat 29 makes the pressure frame 210 stably clamp the sample. The anti-slip slider 211 increases the friction to prevent the sample from sliding. After the clamping is completed, the fluorescence spectrometer is started for detection. After the detection is completed, the pressure frame 210 is rotated in the opposite direction to remove the sample.
