[0031] In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical scheme of the present application will be described in detail below with specific embodiments combined with the drawings.

[0032] In the embodiments of the present application, as shown in the drawings, the storage sample cup comprises a box body 1 and an extrusion assembly 2, see Figures 1 to 4 ; wherein, Figure 1

[0033] The box body 1 is a carrying body, the top of the box body 1 is provided with a detection port 121 communicating with the cavity inside the box body 1, and the side wall of the box body 1 is provided with a taking and placing port 122 facilitating the placement of a sample piece 3 into the cavity, the width of the taking and placing port 122 being greater than the diameter of the sample piece 3.

[0034] The extrusion assembly 2 is arranged in the cavity, and the extrusion end of the extrusion assembly 2 can extrude the sample piece 3 placed in the cavity at the detection port 121.

[0035] Before the detection of the thickness of the sample piece 3, the prepared sample piece 3 can be inserted into the box body 1 through the taking and placing port 122, so that the sample piece 3 is clamped and fixed by the extrusion assembly 2 and the box body 1, and the plane where the sample piece 3 is located is parallel to the plane where the detection port 121 is located, see Figure 4 ;

[0036] Then, the storage sample cup loaded with the sample piece 3 is placed into a spectrometer, and X-rays emitted by the spectrometer are irradiated on the sample piece 3 through the detection port 121 to detect the thickness of the sample piece 3;

[0037] After the detection is completed, the storage sample cup loaded with the sample piece 3 is taken out of the spectrometer, and the sample piece 3 in the cavity is quickly taken out through the taking and placing port 122 to complete the detection process of the thickness of the sample piece 3. In the entire detection process, the box body 1 does not need to be disassembled, the taking / placing steps of the sample piece 3 are simplified, and thus the detection efficiency of the thickness of the sample piece 3 is improved.

[0038] ​It is worth noting that the detection port 121 is circular, and the diameter of the detection port 121 is smaller than the diameter of the sample piece 3. When the sample piece 3 is installed in place, the sample piece 3 is pressed against the top wall of the cavity by the pressing assembly 2. At this time, the edge of the sample piece 3 is clamped on the top wall of the cavity to avoid the situation that the sample piece 3 falls out of the detection port 121.

[0039] In some embodiments, the top of the box body 1 is provided with a gripping port 123, as shown in Figure 1 and Figure 2 The gripping port 123 is communicated to the taking and placing port 122 along the height direction of the box body 1, so as to facilitate the worker to grip the sample piece 3, and the taking and placing of the sample piece 3 is more convenient.

[0040] In some embodiments, the box body 1 includes a box body 11 and a top cover 12, as shown in Figure 3 and Figure 4 ; wherein,

[0041] The top of the box body 11 is provided with a receiving groove 111;

[0042] The detection port 121 and the taking and placing port 122 are arranged on the top cover 12, and the top cover 12 is detachably arranged at the groove opening of the receiving groove 111, so that the receiving groove 111 forms a cavity;

[0043] The detachable box body 11 and the top cover 12 can facilitate the installation and maintenance of the pressing assembly 2, so as to reduce the production difficulty of the storage sample cup and guarantee the service life of the storage sample cup. Preferably, the top cover 12 is detachably connected to the box body 11 by threads. The threaded connection of the top cover 12 and the box body 11 can effectively overcome the pressure provided by the pressing assembly 2, so as to avoid the situation that the top cover 12 and the box body 11 are separated by the pressing assembly 2 during use, so that the structure of the storage sample cup is more stable.

[0044] In some embodiments, the pressing assembly 2 includes a pressing part 21 and a reset part 22, as shown in Figure 3 and Figure 4 ; wherein,

[0045] The pressing part 21 is arranged between the reset part 22 and the detection port 121. The reset part 22 is a spiral spring, and the reset part 22 can press the pressing part 21 towards the detection port 121, so as to press the sample piece 3 at the detection port 121.

[0046] In some embodiments, the pressing surface of the pressing part 21 is a spherical surface, so as to reduce the contact area between the pressing part 21 and the sample 3, and avoid the abrasion between the sample 3 and the pressing part 21 during the installation process, so as to ensure the accuracy of the detection result. Preferably, the edge of the pressing surface of the pressing part 21 is located at a height lower than the height of the taking and placing opening 122.

[0047] When the worker inserts the sample 3 into the taking and placing opening 122, the edge of the sample 3 is clamped on the pressing surface of the pressing part 21. When the worker presses the sample 3, the sample 3 presses the pressing part 21 away from the detection opening 121, so that the sample 3 can be smoothly clamped between the pressing part 21 and the detection opening 121, and tightly adhere to the position of the detection opening 121 under the action of the reset part 22, so as to make the installation of the sample 3 more convenient.

[0048] More preferably, the pressing surface of the pressing part 21 is provided with a friction-reducing coating, so as to further reduce the friction between the pressing part 21 and the sample.

[0049] In some embodiments, the box body 1 and the pressing part 21 are both made of a smooth metal material. During the detection of the thickness of the sample 3, vacuumizing treatment is needed. The smooth metal material has fewer surface pores, which will not affect the efficiency of the vacuumizing, so as to further improve the detection effect.

[0050] It should be noted that the smooth metal material can be 255 alloy stainless steel, S21600 stainless steel, 102Cr17Mo stainless steel, etc.

[0051] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0052] 1) The side wall of the storage sample cup is provided with a taking and placing opening 122 for taking and placing the sample 3. Through the taking and placing opening 122, the sample 3 can be quickly loaded between the pressing assembly 2 and the detection opening 121, or the sample 3 between the pressing assembly 2 and the detection opening 121 can be taken out, so as to improve the taking and placing speed of the sample 3, and improve the detection efficiency.

[0053] Although the preferred embodiments of the present application have been described, those skilled in the art can make further changes and modifications to the embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be interpreted as including all changes and modifications falling within the scope of the present application.

[0054] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
