[0040] During the experimental process of material growth and forming, it is often necessary to carry out the experiment under high temperature and high pressure environment conditions. Therefore, it is necessary to encapsulate the experimental reagents in a vacuum or special atmosphere test tube. After the test tube is sealed, the sealed test tube containing the reagent is placed in a high-temperature pit furnace, high-temperature box furnace or high-temperature tube furnace for heating to complete the experiment.

[0041] In the past, the common practice was to simply place the test tube or simply fix it with high-temperature resistant materials to meet the general needs of the experiment. However, in such high-temperature and high-pressure experiments, there are often experimental errors caused by uneven temperature rise in the furnace space during the heating process, and the test tube may burst.

[0042] To this end, the present invention has been found through experiments, referring to Figure 1 , the figure is a temperature distribution diagram of the high-temperature box furnace in different heating time periods, which provides the temperature distribution in the high-temperature box furnace and the isosurface temperature distribution range, wherein Figure a1, Figure b1 and Figure c1 represent the temperature distribution diagram of the outer surface of the high-temperature box furnace in different heating time periods, Figure a2, Figure b2 and Figure c2 represent the temperature distribution diagram of the interior of the high-temperature box furnace in different heating time periods, Figure a1 and Figure a2 are in the same state (that is, when the high-temperature box furnace is heated to 1200 degrees Celsius), Figure b1 and Figure b2 are in the same state (that is, when the high-temperature box furnace is heated to 1200 degrees Celsius and continues to heat for 6 seconds), Figure c1 and Figure c2 are in the same state (that is, when the high-temperature box furnace is heated to 1200 degrees Celsius and continues to heat for 10 seconds).

[0043] As can be seen from the figure, when the high-temperature box furnace is heated to 1200 degrees Celsius, the temperature is mainly distributed at the side heat source. After continuing to heat for 6-10 seconds, the heated air gradually diffuses from the heat source to the center of the furnace body. There is a significant difference between the heating at the non-heat source position in the furnace body and the heating at the heat source. The temperature difference between the bottom position of the furnace body and the top position of the furnace body is obvious, but the temperature near the middle and upper part of the furnace body is relatively uniform. How to use this discovery to design a test tube rack that can assist in placing test tubes, so as to ensure that the test tubes in the test tube rack are heated evenly as much as possible, to reduce the experimental errors caused by the experiment and the test tube bursting caused by uneven heating, is what this application wants to explore and solve.

[0044] For this purpose, see Figure 2 The embodiment of the present application provides a test tube rack structure for use in a high temperature environment, comprising a base 1, a support 2, a test tube box 3 and an angle adjustment assembly, wherein the support 2 is arranged on the base 1, the test tube box 3 is arranged above the base 1 and located on one side of the support 2, the test tube box 3 is used to place test tubes, and the angle adjustment assembly comprises a movable adjustment rod 41, one end of the movable adjustment rod 41 is rotatably arranged on the top of the support 2, and the other end is connected to the top of the test tube box 3. The movable adjustment rod 41 adjusts the test tube box 3 to a first space by adjusting its rotational position relative to the support 2, wherein the first space is a space with a small temperature change in a high temperature environment, and the high temperature environment can be 100-1100°C.

[0045] That is to say, in this embodiment, by adjusting the rotational position of the movable adjusting rod 41 relative to the supporting member 2, the test tube box 3 has a certain inclination angle relative to the supporting member 2, thereby facilitating the test tube box 3 to be adjusted to a space with a small temperature change in a high temperature environment (for example, a high temperature box furnace), thereby reducing the experimental error caused by the experiment and the problem of test tubes in the test tube box 3 bursting due to uneven heating.
