In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0026] The following combination Figure 1-Figure 3 The test bench of the present invention is described.

[0027] Figure 1 The exploded diagram of the test bench provided by the embodiment of the present utility model is illustrated. Figure 1 The test bench provided by the present invention includes a carrier 100, a cover and pressure member 200, and a connector 300. The carrier 100 is provided with a plurality of sample slots 110, which are spaced apart and used to store samples. The cover and pressure member 200 is disposed in the sample slots 110 and is used to secure the samples. The connector 300 is detachably disposed between the carrier 100 and the cover and pressure member 200 and is used to secure the carrier 100 and the cover and pressure member 200.

[0028] In the above scheme, the carrier 100 forms the foundation of the entire test bench and is equipped with multiple sample slots 110 spaced apart at intervals. These sample slots 110 are used to precisely position the samples to be tested, ensuring that each sample maintains a stable position and shape during the measurement process. Furthermore, by designing multiple sample slots 110, the test bench can accommodate multiple samples for measurement simultaneously, significantly improving measurement efficiency. This is particularly important for scientific research projects that require processing large numbers of samples. The cover and pressure member 200 is designed to cover and secure the samples placed in the sample slots 110. This design not only helps prevent sample movement or leakage during measurement but also reduces the impact of air on scattered signals, thereby improving measurement accuracy. The connector 300 serves as a bridge between the carrier 100 and the cover and pressure member 200, securely connecting them together in a detachable manner. This design allows users to quickly and easily install and disassemble the test bench, while also facilitating sample replacement and test bench maintenance. Furthermore, the detachable design facilitates cleaning and maintenance of the test bench, extending the service life of the equipment. The utility model is not only suitable for measuring solutions or viscous samples, but also can be applied to powdery samples.

[0029] Materials for the carrier 100 and cover 200 can be high-strength, corrosion-resistant, and easy-to-clean materials, such as stainless steel or aluminum alloy. These materials not only possess excellent mechanical properties, capable of supporting the weight of multiple samples while maintaining a stable shape, but also effectively resist corrosion and wear, extending the service life of the test bench. Alternatively, non-toxic, corrosion-resistant materials with minimal impact on X-ray transmission, such as polytetrafluoroethylene (PTFE) or high-purity quartz glass, can be selected. These materials not only prevent contamination of the samples but also ensure smooth X-ray transmission, reducing interference from scattered signals. The connector 300 can specifically be a bolt, which detachably connects the carrier 100 and cover 200.

[0030] In some possible embodiments, the carrier 100 can be designed to be in the shape of a flat tray, which is convenient for placing and fixing multiple sample troughs 110. In order to increase stability, reinforcing ribs or supporting feet can be added to the bottom of the tray. At the same time, the edge of the tray can be designed to be rounded or chamfered to reduce damage to the operator and prevent the sample from accidentally slipping. The shape of the sample trough 110 should be designed according to the specific shape and size of the sample to ensure that the sample can fit tightly and is not easy to move. For example, for liquid samples, it can be designed to be a cylindrical or square trough with a groove; for solid samples, it can be designed to be a rectangular or circular trough with a fixed card slot. In addition, the bottom of the sample trough 110 can be designed to be inclined or have a drainage hole to facilitate cleaning and removal of residues. The shape of the cover 200 should match the carrier 100 to ensure that the sample can be completely covered and fixed.

[0031] Figure 2 The structural diagram of the supporting member of the test bench provided by the embodiment of the present utility model is illustrated. Figure 2 In some embodiments of the present invention, a first detection hole 120 is provided in the middle of the sample tank 110, and the first detection hole 120 is coaxially arranged with the sample tank 110, and the first detection hole 120 is used to provide a channel for sample detection.

[0032] In the above structure, the first detection hole 120 is coaxially arranged with the sample slot 110, ensuring that the X-ray beam can directly pass through the first detection hole 120 and focus on the center of the sample. This design reduces the deviation and interference of scattered light and improves the accuracy of the measurement. The presence of the first detection hole 120 can also enable the X-rays to form a more concentrated scattering area when penetrating the sample, thereby improving the intensity and clarity of the scattered signal. This is crucial for subsequent data analysis and processing. Secondly, once the sample is placed in the sample slot 110, it can be quickly and accurately detected through the first detection hole 120 without the need for additional adjustment or positioning steps. This greatly saves experimental time and improves experimental efficiency. In some possible embodiments, the first detection hole 120 can be appropriately adjusted according to the needs of different samples. For example, for detection requiring a specific angle or direction, this can be achieved by changing the position or shape of the first detection hole 120.

[0033] Reference Figure 1 In some embodiments of the present invention, a seal 400 is provided inside the carrier 100, a sample ring 500 is provided inside the seal 400, and the sample is provided inside the sample ring 500; wherein the seal 400 is used to prevent the sample from leaking.

[0034] In the above structure, the integrated design of seal 400 and sample ring 500 ensures sample stability and safety during measurement, effectively preventing contamination of test results and the test environment by sample leakage. By preventing sample leakage, external interference with the scattered signal is reduced, thereby improving measurement accuracy and reliability. Without concerns about sample leakage, experimenters can focus more on experimental operations and data analysis, improving experimental efficiency. Furthermore, this design is applicable to a variety of sample types, including liquids, viscous substances, and solid powders, demonstrating its versatility and adaptability.

[0035] Specifically, the seal 400 should be made of materials with good sealing, corrosion resistance and high temperature resistance, such as fluororubber, silicone or polytetrafluoroethylene (PTFE). These materials can maintain stable sealing performance in extreme environments to prevent sample leakage. The seal 400 should also have a certain degree of elasticity and wear resistance to ensure that the seal 400 can maintain a good sealing effect during long-term use. The shape of the seal 400 is customized according to the shape of the sample slot 110 to ensure that the seal 400 can fit tightly on the carrier 100 to form an effective sealing space. O-rings, rectangular sealing rings or special-shaped sealing rings can be used to adapt to different sealing requirements and installation conditions. It is necessary to ensure that the seal 400 has a certain amount of compression and rebound performance to ensure that it can form a tight sealing effect when subjected to pressure and can return to its original shape after the pressure is released.

[0036] The material of the sample ring 500 should be selected to match the properties of the sample to avoid contamination or impact on the sample. For example, for biomacromolecule samples, non-toxic, non-polluting medical-grade materials can be selected; for samples with active chemical properties, corrosion-resistant materials can be selected. The material of the sample ring 500 should also have a certain hardness and stability to ensure that the shape and position of the sample can be maintained unchanged during the measurement process. The shape of the sample ring 500 should be designed according to the shape and size of the seal 400 to ensure that the sample can fit tightly inside the seal 400 and maintain a stable position. Cylindrical, square or special-shaped sample rings 500 can be used to accommodate samples of different shapes and sizes.

[0037] Reference Figure 1 In some embodiments of the present invention, the upper surfaces of the sealing member 400 and the sample ring 500 are coplanar with the upper surface of the carrier 100. This arrangement ensures that the sealing member 400 and the sample ring 500 can withstand the weight and pressure of the sample and maintain a stable shape during the measurement process.

[0038] In some embodiments of the present invention, a carrier sheet is provided at the bottom of the sealing member 400 and a cover sheet is provided at the top of the sealing member 400. The carrier sheet, the cover sheet, and the sample ring 500 cooperate to form a sealed cavity in which the sample is located. The carrier sheet and the cover sheet can be plastic sheets.

[0039] During the measurement process, the carrier sheet is first placed inside the sample well 110. The seal 400 and sample ring 500 are then placed on the carrier sheet. The sample is then placed inside the sample ring 500. A cover sheet is then placed on top of the seal 400 and sample ring 500, and the sample is secured with the cover press 200. Subsequently, the carrier sheet and cover press are tightly connected using connectors to create a closed measurement environment. Finally, the test bench is placed in a vacuum environment for small-angle X-ray scattering measurements.

[0040] Reference Figure 1 In some embodiments of the present invention, the carrier 100 is provided with a plurality of first connection holes 130, and the cover pressing member 200 is provided with a plurality of second connection holes 220. The first connection holes 130 correspond to the second connection holes 220 one-to-one, and the connection members 300 penetrate the second connection holes 220 and the corresponding first connection holes 130 to secure the carrier 100 and the cover pressing member 200. The first connection holes 130 can be threaded holes, and the connection members 300 are bolts. When arranging the first connection holes 130 and the second connection holes 220, they should be aligned to facilitate the penetration of the bolts, thereby connecting the carrier 100 and the cover pressing member 200.

[0041] Reference Figure 1In some embodiments of the present invention, the cover pressing member 200 is provided with a plurality of second detection holes 210, and the second detection holes 210 are arranged one-to-one corresponding to the first detection holes 120. It should be noted that the second detection holes 210 and the first detection holes 120 are interconnected to form a channel.

[0042] In the above structure, the first detection hole 120 and the second detection hole 210 are interconnected, forming a complete detection path from the external detection device to the interior of the sample or a specific area. This allows the detection signal to be smoothly transmitted to the test area and the required feedback information to be collected. The interconnected design helps to enhance the strength and stability of the detection signal and reduce signal attenuation and interference during transmission. This helps to improve the sensitivity and accuracy of detection, ensuring the reliability of experimental results.

[0043] Reference Figure 1 In some embodiments of the present invention, the second detection hole 210 includes a gradient section and a straight section that are interconnected. The straight section is located on the side facing the supporting member 100 , and the diameter of the straight section is the same as the diameter of the first detection hole 120 .

[0044] Figure 3 The schematic diagram of the structure of the cover pressing member of the test bench provided by the embodiment of the present utility model is illustrated. Figure 2 and Figure 3 In some embodiments of the present invention, one of the carrier 100 and the cover pressing member 200 is provided with a stopper 140, and the other of the carrier 100 and the cover pressing member 200 is provided with a stopper groove 230. The stopper 140 and the stopper groove 230 correspond to each other and limit each other. Specifically, the stopper 140 is provided on the top surface of the carrier 100, and the stopper groove 230 is provided on the bottom surface of the cover pressing member 200. In other possible embodiments, the stopper groove 230 may be provided on the top surface of the carrier 100, and the stopper 140 may be provided on the bottom surface of the cover pressing member 200.

[0045] Reference Figure 1 In some embodiments of the present invention, at least one of the carrier 100 and the cover pressing member 200 is provided with a fixing hole 150, which is used to secure the test bench. The fixing hole 150 is threaded. Specifically, the fixing hole 150 may be provided only on the carrier 100, only on the cover pressing member 200, or both on the carrier 100 and the cover pressing member 200.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
