Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of X-ray diffraction testing, and relates to a block solid sample holder installed on an X-ray diffractometer, in particular to a block solid sample holder for an X-ray diffractometer with adjustable height. Background Art
[0002] X-ray diffractometer is a commonly used equipment for phase analysis and crystal structure characterization, and is widely used in various fields such as physics, chemistry, earth science, and materials science.
[0003] During the test, the sample holder directly affects the quality and efficiency of the test. The samples tested are mainly powder samples and block samples. The traditional block sample holder is a rectangular aluminum sheet with a hollow in the middle. The sample is fixed in the hollow in the middle of the sample holder with plasticine by the inverted method. During the test, the sample is supported by the plasticine. With this sample preparation method, if the sample is thin or small in size, the plasticine is around the sample, and it is easy to measure the peak of the plasticine during the test, resulting in erroneous experimental data. Most of the block samples are made of metal, and thick samples are heavier. It is difficult to hold the sample steadily with plasticine. If the sample sinks during the test, it will cause the peak of the spectrum to shift, or even the test to fail.
[0004] Therefore, the field of X-ray diffraction urgently needs a simple and practical test block solid sample stage to solve the problems in the above-mentioned background technology. Utility Model Content
[0005] The utility model aims to solve the above problems and provides a sample table with adjustable height for testing block solid samples by an X-ray diffractometer.
[0006] The technical solution of this utility model:
[0007] A block solid sample holder for an X-ray diffractometer with adjustable height, comprising a base 1, a test reference plane 2, an insertion position 3, a circular tray 4, a screw 5 and a nut 6;
[0008] The base 1, the test reference plane 2 and the insertion position 3 are an integrated structure, and an integrated hollow frame is formed between the base 1 and the test reference plane 2 through four support rods; the insertion position 3 is an extended flat plate of the test reference plane 2; a square through hole is opened on the test reference plane 2; the screw 5 passes through the base 1, and one end of the screw 5 located in the hollow frame is connected to the circular tray 4, and the other end is provided with a nut.
[0009] Beneficial effects of the utility model:
[0010] (1) The utility model is adapted to most X-ray diffractometers with insert-type sample loading, without the need to modify the goniometer sample stage, easy to install and disassemble, convenient to operate, and the sample is easy to prepare, especially suitable for Rigaku X-ray diffractometers.
[0011] (2) By rotating the screw, the height of the tray is adjusted to be suitable for bulk solid samples with sizes varying within a certain range, solving the problem that samples with large self-weights cannot be supported, and having a large application range.
[0012] (3) The material of the tray has no background interference, which can effectively solve the problem of interference peaks of small samples with plasticine. Description of the Drawings

[0016] The following further describes the detailed embodiment of the utility model in combination with the drawings and technical solutions.
[0017] As Figure 1 shown, a bulk solid sample holder for an X-ray diffractometer with adjustable height includes a base 1, a test reference plane 2, an insertion position 3, a circular tray 4, a screw 5 and a nut 6;
[0018] The base 1, the test reference plane 2 and the insertion position 3 are of an integral structure. An integral hollow frame is formed between the base 1 and the test reference plane 2 through four support rods; the insertion position 3 is an extended flat plate of the test reference plane 2; a square through-hole is opened on the test reference plane 2; the screw 5 passes through the base 1, one end of which located in the hollow frame is connected to the circular tray 4, and the other end is equipped with a nut.
[0019] The outer shape of the test reference plane 2 is rectangular, with a length of 50 mm and a width of 35 mm.
[0020] The side length of the square through-hole is 20 mm.
[0021] The diameter of the circular tray 4 is 15 mm and the thickness is 3 mm.
[0022] The center of the screw 5 and the center of the square through-hole are on the same axial line.
[0023] The corner position between the base 1 and the test reference plane 2 is an arc surface or a right-angle structure.
[0024] The base 1, the test reference plane 2, and the insertion position 3 are made of aluminum alloy or stainless steel.
[0025] The circular tray 4 is made of polyester fiber or other amorphous materials.
[0026] Combined with the attached Figure 2 Describe a practical process of the present utility model:
[0027] In this embodiment, an appropriate amount of plasticine is selected according to the size of the sample and placed on the circular tray 4, and then the test sample 7 is placed. A glass plate is covered on the test reference plane 2. One hand holds the glass plate against the test reference plane 2, and the other hand rotates the nut 6 to raise the test sample 7 until it fits tightly with the glass plate. Remove the glass plate, insert the sample holder into the insertion position 3 of the X-ray diffractometer, and it can be used.
