[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] A sample tube rack with adjustable height, such as Figs. 1-3 As shown, its structural relationship is as follows: it includes a bottom plate 1 and a limiting plate 3 with corresponding limiting grooves 11 and limiting holes 31, and is provided with a side plate 2 and multiple limiting plates 3;

[0027] Side plate 2 is upright and fixed to the top of base plate 1. Multiple mounting structures are opened on multiple limiting plates 3 and along the height of side plate 2. The limiting plates 3 and side plate 2 can be detachably installed and fixed through the mounting structures.

[0028] In actual use, the operator can select a suitable height on the side plate 2 according to the required sample tube height, and install and fix the limiting plate 3 and the side plate 2 detachably through the installation structure to meet the sample tube placement needs.

[0029] Preferably, the installation structure consists of multiple side plate slots 21 arranged in a row along the height of the side plate 2, and a limiting plate slot 32 corresponding to the side plate slots 21 on the limiting plate 3. The limiting plate slot 32 is engaged with any side plate slot 21 to detachably install and fix the limiting plate 3 to the side plate 2.

[0030] Preferably, the side plate groove 21 is an inclined groove that slopes upward from the inside to the outside, and the limiting plate 3 is installed in a corresponding inclined posture from the inside to the outside. By utilizing gravity, the limiting plate can be effectively prevented from falling off during use without increasing the difficulty of installing the limiting plate, thus improving the safety of the sample tube rack.

[0031] Preferably, multiple side plate slots 21 are arranged in a row along the height on both sides of the side plate 2.

[0032] This expands the number of limiting plates 3 that can be installed inside the sample tube rack, allowing more sample tubes of various sizes and quantities to be placed on the sample tube rack.

[0033] Preferably, a pair of side plates 2 are symmetrically and uprightly fixed on the base plate 1, and a limiting plate slot 32 is opened on each of the two ends of the limiting plate 3. The pair of limiting plate slots 32 are respectively engaged with the side plate slots 21 on the pair of side plates 2. The pairing of side plates 2 and limiting plate slots 32 improves the symmetry of the sample tube rack structure, optimizes the force distribution of the sample tube rack, thereby improving the stability of the sample tube rack structure and extending the service life of the sample tube rack.

[0034] Preferably, the limiting plate 3 has multiple limiting holes 31 with the same or different diameters.

[0035] In actual setup, a single limiting plate 3 can have multiple limiting holes 31 with the same diameter or different diameters. The diameters of the limiting holes 31 on multiple limiting plates 3 can also be different. When using, the appropriate selection can be made according to the specific needs of the experimental sample tube.

[0036] Preferably, the limiting groove 11 is a frustum-shaped groove with a diameter decreasing from top to bottom, in order to accommodate the limiting needs of sample tubes of different diameters.

[0037] Preferably, the side plate 2 and the bottom plate 1 are integrally formed into a whole structure.

[0038] Preferably, the limiting holes 31 and the limiting grooves 11 are arranged in rows at equal intervals or in an array.

[0039] Preferably, the side plate slots 21 are symmetrically arranged at equal intervals.

[0040] In practical use, the following process is included:

[0041] Before the experiment, the experimenters selected a suitable limiting plate 3 according to the height and diameter of the sample tube, and selected a set of side plate slots 21 of suitable height on the side plate 21. The limiting plate slots 32 and the set of side plate slots 21 were fitted together to make the limiting plate 3 and the side plate 21 detachable and fixed.

[0042] During the experiment, when it is necessary to place the sample tube, the experimenter selects a limiting hole 31 with appropriate height and size, passes the sample tube through the limiting hole 31, and securely places the middle and bottom of the sample tube within the limiting hole 31 and the corresponding limiting groove 11, respectively.
