[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0026] Reference Figure 1-4The chromatographic column storage cabinet includes a cabinet body 1, and also includes: a plurality of drawers 101, which are slidably connected in the cabinet body 1; a plurality of sliding blocks 201, which are connected to the drawers 101; a fixing device 202, which is fixedly connected to the sliding block 201; a fixing device 203, which is slidably connected to the sliding block 201, and the fixing device 202 and the fixing device 203 are arranged in a U shape after being matched; a spring member 2021, which is connected to the fixing device 202, and the other end of the spring member 2021 is connected to the fixing device 203, and the drawer 101 is connected to the cabinet body 1. 1 is fixedly connected with a mounting strip 104, a sliding block 201 is slidably connected in the mounting strip 104, a fixing device 1 202 is provided with a mounting groove, a connecting rod 2031 matching the mounting groove is fixedly connected to the fixing device 203, a spring member 2021 is located in the mounting groove, one end of the connecting rod 2031 is connected to the spring member 2021, a sponge pad 103 is connected to the drawer 101, a convex block 1022 is provided in the cabinet body 1, and a groove 1021 matching the convex block 1022 is provided on the drawer 101.

[0027] like Figure 3 As shown, the first fixer 202 and the second fixer 203 are arranged in a U shape after being spliced, and the opening is small and the opening is rounded to facilitate insertion and improve the clamping effect.

[0028] When in use, the chromatographic column is inserted through the opening between the fixture 1 202 and the fixture 2 203. The force generated at this time will move the fixture 203, and the spring member 2021 will extend accordingly. When it is subsequently inserted into the U-shaped bottom, the chromatographic column will be fixed by the fixture 1 202 and the fixture 2 203 under the action of the spring member 2021. At this time, chromatographic columns of different sizes can be fixed. However, not all sizes of chromatographic columns can be fixed. If it is smaller than the U-shaped opening, or exceeds the moving range of the fixture 203, clamping and fixation cannot be achieved.

[0029] After the clamping is completed, the drawer 101 can be reinserted into the cabinet 1 to facilitate the storage of the chromatographic column.

[0030] It is important to note that:

[0031] The whole frame of cabinet 1 is made of stainless steel;

[0032] Fillers can be added to the inner side of the first fixer 202 and the second fixer 203. The fillers can be rubber to play an anti-slip and fixing role. Example

[0033] Reference Figure 1-4, a chromatography column storage cabinet is basically the same as Example 1, and further: an extrusion plate 105 is slidably connected in the mounting bar 104, a screw rod 106 is threadedly connected to the bottom of the drawer 101, one end of the screw rod 106 is rotatably connected to the extrusion plate 105, and the extrusion plate 105 is used to limit the movement of the sliding block 201.

[0034] During specific use, chromatographic columns of the same brand but different models can be placed in the drawer 101. The same model can be placed together, and a certain gap can be set between chromatographic columns of different models. After the setting is completed, the bottom of the sliding block 201 can be restricted by rotating the screw rod 106 and the extrusion plate 105 to prevent the sliding block 201 from moving, thereby achieving fixation and facilitating classified placement.

[0035] An anti-slip knob may be provided on the screw member 106 to facilitate the rotation of the screw member 106 .

[0036] The utility model can fix chromatographic columns of different sizes through the movable second fixer 203, which is easy to operate, has good stability, and is convenient for laboratory use. At the same time, the movable first fixer 202 and the second fixer 203 can classify chromatographic columns of different models, which is convenient for classification management.

[0037] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
