[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In order to solve the technical problem in the prior art that the sealing performance between the sealing cover and the base is poor, thereby causing a certain influence on the accuracy of the experimental results, the utility model provides a sealed XRD sample stage.

[0028] See also Figure 1 , Figure 1 Schematic diagram of the three-dimensional structure of a sealed XRD sample stage in an embodiment of the utility model. The sealed XRD sample stage includes a base 1 and a cover 2 .

[0029] See also Figure 1-Figure 5 The base 1 comprises a bottom plate 11, and an annular sealing groove 111 is provided on the bottom plate 11, and a sealing ring 112 is placed in the sealing groove 111;

[0030] The cover body 2 includes a cover plate 21 and a transparent cover 22. The cover plate 21 is detachably fixed to the bottom plate 11 and abuts against the sealing ring 112. A through hole is opened at the center of the cover plate 21, and the transparent cover 22 is disposed above the through hole to close the through hole.

[0031] When in use, first place the sample at the center of the base plate 11, then cover the base plate 11 with the cover plate 21, and fix the cover plate 21 to the base plate 11 to achieve sample packaging, and then put the entire sample table into the box of the X-ray diffractometer. The X-rays emitted by the X-ray diffractometer can pass through the transparent cover 22 and irradiate the sample.

[0032] The technical solution provided by the utility model is to fix the transparent cover 22 on the cover plate 21 and arrange a sealing ring 112 between the cover plate 21 and the bottom plate 11 to achieve sealing, and the sealing effect is good, which can improve the accuracy of the experimental results.

[0033] In one embodiment, see Figure 1-Figure 4 The center of the bottom plate 11 is formed with a placement protrusion 113, which is inserted into the through hole and fits with the through hole. The placement protrusion 113 is used to place samples. The placement protrusion 113 is used to raise the sample to prevent the through hole from blocking the X-ray irradiation of the sample. At the same time, the placement protrusion 113 can also play a positioning role, which is convenient for the user to align the bottom plate 11 with the cover plate 21.

[0034] In one embodiment, see Figure 1-Figure 4 The thickness of the placement protrusion 113 is equal to the thickness of the cover plate 21, so that the sample will be located above the through hole of the cover plate 21 to prevent the through hole from blocking the X-ray irradiation of the sample.

Specifically, some XRD devices are provided with a socket, and the plug rod 12 can be inserted into the socket to achieve fixation. However, some devices do not have a socket, so there is no need to use the plug rod 12, and the sample stage can be directly placed on the detection platform of the XRD device.

[0037] In one embodiment, see Figure 3-Figure 5 A receiving groove is formed at the opening of the clearance hole 211, and the receiving groove is used to receive the screw head of the corresponding fixing screw, so that the screw head can be hidden and the aesthetics is improved.

[0038] In one embodiment, see Figure 3 and Figure 5 The transparent cover 22 includes two end caps 221 and an arc plate 222. The two end caps 221 are respectively fixed to the two sides of the through hole of the cover plate 21, and the two ends of the arc plate 222 are respectively fixed to the two end caps 221. Preferably, the arc plate 222 is a transparent plastic arc plate. Both sides of the arc plate 222 are fixedly connected to the cover plate 21.

[0039] In one embodiment, see Figure 3 and Figure 5The cover plate 21 is also provided with two mounting grooves 212 , and the two sides of the arc plate 222 are respectively adhered and fixed to the inner side walls of the two mounting grooves 212 .

[0041] The technical solution provided by the utility model is to fix the transparent cover 22 on the cover plate 21 and arrange a sealing ring 112 between the cover plate 21 and the bottom plate 11 to achieve sealing, and the sealing effect is good, which can improve the accuracy of the experimental results.
