[0001] The invention relates to the technical field of chromatography experiment cabinets, in particular to a space compression chromatography experiment cabinet. Background Art

[0002] At present, in experimental research in biochemistry and other related fields, chromatography test cabinets are a key experimental equipment. They provide a stable low-temperature environment for biochemical chromatography analysis of various enzymes, peptides, macromolecules, nucleic acids and other substances. However, existing chromatography test cabinets have obvious limitations in terms of internal space layout.

[0003] The design of the layers of chromatography cabinets is mostly fixed in spacing and uniform in specifications; in actual experiments, there are many types of chromatography columns, special-shaped experimental instruments, etc., and their sizes and shapes vary; for example, some new high-efficiency chromatography columns have a different ratio of height to diameter from traditional chromatography columns, and some customized experimental instruments have irregular shapes. When these experimental instruments are placed in traditional chromatography cabinets, they are often not placed properly because the spacing between the layers cannot be adjusted, resulting in a waste of space. Moreover, the fixed internal layout cannot meet the needs of placing experimental instruments of different types and sizes at the same time. Experimenters often need to spend a lot of time adjusting the placement of items, and may even be unable to use some necessary experimental instruments due to space limitations, which seriously affects the efficiency of the experiment and the flexibility of the experimental design, thereby reducing the practicality of the chromatography cabinet.

[0004] In view of this, a space compression chromatography experimental cabinet is urgently needed. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example

[0032] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a space compression chromatography experimental cabinet, including a cabinet body 10, two mounting columns 11 and two partitions 12, two stabilizing members 13 are arranged on both sides of the cabinet body 10 near one side of the partition 12 and on one side of the two mounting columns 11 near the partition 12, and both sides of the two partitions 12 are fixedly connected to the side of the stabilizing member 13, and a partition 20 is slidably connected between the two partitions 12 through a sliding member 14, wherein:

[0033] The partition 20 at least includes an H-plate 21, an adjusting member 22 is disposed inside the H-plate 21, a fixing member 23 is disposed in the middle of the adjusting member 22, one end of the fixing member 23 extends to the inside of the sliding member 14, and is used to fix the position of the H-plate 21 after horizontal movement;

[0034] When the sliding member 14 slides, the partition member 20 can be adjusted in position according to the width of the experimental device, and the adjusted position is fixed by the fixing member 23;

[0035] The adjusting member 22 and the stabilizing member 13 work in cooperation with each other and can adjust the distance between the two partitions 12 according to the height of the experimental equipment.

[0036] Since only one partition 20 is provided between the two partitions 12, when the position of the partition 20 is adjusted and deviates to any side of the partition 12, some undesirable conditions may occur. On the one hand, the two partitions 12 may become stuck during the process of adjusting the upper and lower positions, which will seriously affect the smoothness of the adjustment operation; on the other hand, the two partitions 12 may be unstable in support. The instability not only affects the normal use of the laboratory cabinet, but also threatens the safety of the experimental items placed therein, thereby reducing the practicality of the chromatography laboratory cabinet. Therefore, according to Figure 1 , Figure 2 and Figure 6As shown, the specific structure of the stabilizer 13 is disclosed. The stabilizer 13 at least includes a track 131, and an electric telescopic rod 132 is arranged inside the track 131 (it should be noted that since there are multiple electric telescopic rods 132, the specific position of the electric telescopic rod 132 can be Figure 2 As can be seen, a slider 133 is provided at the end of the piston rod inside the electric telescopic rod 132 , and one side of the slider 133 close to the opening of the track 131 is fixedly connected to the side of the partition 12 .

[0037] When the electric telescopic rod 132 is turned on to work (multiple electric telescopic rods 132 are controlled by a unified start button so that multiple electric telescopic rods 132 work simultaneously, and the start button is not shown in the attached figure), the piston rod inside the electric telescopic rod 132 is pushed or reset to drive the partition 12 to adjust downward or upward, and can cooperate with the adjustment member 22 to adjust the distance between the heights of the two partitions 12. Not only can the distance between the heights of the two partitions 12 be adjusted, but the heights of the three spaces separated by the two partitions 12 can also be adjusted as needed, which greatly increases the flexibility of the use of the chromatography laboratory cabinet and meets the diverse requirements of the space height for placing different experimental items; it can also enhance the stability of the two partitions 12 after the position adjustment, avoid safety problems that may be caused by the instability of the partitions 12, improve the safety of the use of the chromatography laboratory cabinet, and thus improve the reliability of the use of the chromatography laboratory cabinet.

[0038] Considering that the separator 20 is used to separate the two partitions 12, the positions of the two partitions 12 are adjusted, and the separator 20 also needs to be adjusted accordingly to achieve a better adaptability effect. This is also to increase the rationality and flexibility of the space between the two partitions 12. Therefore, according to Figure 1-Figure 4 As shown, the specific structure of the adjusting member 22 is disclosed. The adjusting member 22 includes at least two bidirectional cylinders 221. The two bidirectional cylinders 221 are respectively located inside the two sides of the H plate 21. The piston rods at both ends of the two bidirectional cylinders 221 are provided with adjusting frames 222.

[0039] The two-way cylinder 221 is turned on to make it work (the two-way cylinder 221 works in conjunction with the electric telescopic rod 132), and the piston rods at both ends of the two-way cylinder 221 push the adjustment frame 222 away from the H plate 21. At the same time, the piston rod inside the electric telescopic rod 132 performs a corresponding reset operation, which can increase the height between the two partitions 12. Similarly, when the piston rods at both ends of the two-way cylinder 221 are reset, the piston rod inside the electric telescopic rod 132 performs a pushing operation, thereby reducing the height between the two partitions 12. Not only can the space size be flexibly adjusted, but the space utilization efficiency can also be further optimized, providing a more suitable space layout for different experimental scenarios, thereby improving the practicality of the chromatography laboratory cabinet.

[0040] In the process of using the chromatography laboratory cabinet, due to the diversity of the sizes of the laboratory instruments, especially the different widths, it is required that we can flexibly adjust the position of the partition 20 in the horizontal direction. Through such adjustment, the space separated by the partition 20 can be used more reasonably, thereby effectively increasing the utilization rate of the storage space. Therefore, according to Figure 1 , Figure 3 and Figure 7 As shown, the specific structure of the sliding member 14 is disclosed. The sliding member 14 includes at least two sliding rods 142. The two sliding rods 142 are respectively located in the middle of the two adjustment frames 222 on one side close to the partition 12. The two partitions 12 are provided with a sliding groove 141 on one side close to the H-plate 21 for sliding connection with the sliding rod 142.

[0041] Open the fixing piece 23, push the H plate 21, and make the slide bar 142 slide inside the slide groove 141, so that the position of the partition 20 in the horizontal direction is adjusted, and the fixing piece 23 is used to fix the position of the adjustment frame 222 after adjustment, thereby increasing the stability of the chromatography laboratory cabinet, ensuring that the experimental equipment can be stored in the most suitable space, avoiding space waste, and facilitating the convenience of experimental operation. At the same time, because the reasonable space layout can make the experimental equipment more orderly, the protection of the experimental equipment is increased, and damage such as collision and extrusion caused by narrow space or improper placement is avoided, thereby improving the practicality of the chromatography laboratory cabinet.

[0042] It can be seen that the fixing member 23 is important for stabilizing the position of the separator 20 and can increase the safety of the separator 20. Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, the specific structure of the fixing member 23 is disclosed. The fixing member 23 includes at least two elastic members 232. Two mounting grooves 231 for mounting the two elastic members 232 are provided in the middle of the sliding rod 142 close to the adjusting frame 222. A connecting rod 233 is provided at one end of the two elastic members 232 away from the mounting groove 231. A fixing column 234 is provided in the middle of the connecting rod 233 close to the elastic member 232. A pulling member 235 is provided on the side of the connecting rod 233 away from the elastic member 232.

[0043] Next, the specific structure of the pulling member 235 is disclosed. Figure 8 As shown, the pulling member 235 at least includes an extension column 2351, which extends from one side of the connecting rod 233 to an end of the adjustment frame 222 close to the H plate 21, and is provided with a rotating ball 2352, and the outer wall of the rotating ball 2352 is rotatably connected to a handle 2353.

[0044] When the position of the partition 20 needs to be adjusted, the handle 2353 is held tightly and pulled toward the side away from the slide rod 142. During this process, the elastic member 232 is deformed and elongated due to the force, driving the connecting rod 233 to move toward the inside of the adjustment frame 222. At the same time, the bottom of the handle 2353 moves out of the inside of the adjustment frame 222 (through the Figure 8 It can be known that the interior of the two adjustment frames 222 mentioned above refers to two specific positions). Next, the handle 2353 is rotated to make the rotating ball 2352 rotate inside the handle 2353, so that the handle 2353 and the adjustment frame 222 are in a vertical state, thereby stabilizing the position of the handle 2353. After that, the other fixing member 23 is processed in the same manner, and the position of the partition 20 is adjusted. After the adjustment is completed, the handle 2353 is rotated again to make the rotating ball 2352 rotate inside the handle 2353, so that the handle 2353 and the adjustment frame 222 are restored. When the cabinet is in a horizontal state again, with the help of the resilience of the elastic member 232, the fixed column 234 will move toward the inner wall of the slide groove 141 and exert pressure on the inner wall of the slide groove 141, thereby achieving the purpose of stabilizing the position of the partition 20; it can not only ensure that the partition 20 remains stable in the adjusted position and avoid affecting the storage layout of experimental instruments due to accidental movement, but also is easy to operate, thereby improving the convenience and flexibility of the use of the entire chromatography laboratory cabinet, providing a reasonable storage space for experimental instruments of different sizes during the experiment, and at the same time, further improving the safety of experimental operations and the stability of the experimental environment.

[0045] Considering the limited size of the fixing column 234, the stability of the position of the partition 20 may be affected. Figure 5 and Figure 8As shown, a non-slip pad 236 is provided on the side of the fixed column 234 away from the connecting rod 233. The non-slip pad 236 can increase the friction between the fixed column 234 and the inner wall of the slide groove 141, which can not only enhance the stability of the position of the partition 20 and avoid displacement of the partition 20 due to external factors such as vibration and slight collision during the experiment, thereby ensuring the stability of the storage space for experimental equipment, but also improve the reliability of the entire chromatography laboratory cabinet, reduce experimental errors and safety hazards that may be caused by changes in the position of the partition 20, and at the same time, the provision of the anti-slip pad 236 can also reduce the wear of the fixed column 234 and the inner wall of the slide groove 141, extend the service life of both, reduce equipment maintenance costs, and avoid economic losses.

[0046] In summary, the working principle of this solution is as follows: the height between the two partitions 12 can be adjusted by the electric telescopic rod 132 and the two-way cylinder 221 working together; then, by opening the fixing member 23 and pushing the H plate 21, the sliding member 14 slides to adjust the size of the two spaces separated by the partition 20, and the fixing member 23 is used to fix the position of the partition 20. The specific situation is as follows:

[0047] When the height between the two partitions 12 needs to be adjusted, the two-way cylinder 221 and the electric telescopic rod 132 are turned on to work together, and the piston rods at both ends of the two-way cylinder 221 push the adjustment frame 222 away from the H plate 21. At the same time, the piston rod inside the electric telescopic rod 132 performs a corresponding reset operation, so that the slider 133 slides inside the track 131, thereby increasing the height between the two partitions 12. Similarly, when the piston rods at both ends of the two-way cylinder 221 are reset, the piston rod inside the electric telescopic rod 132 performs a pushing operation, so that the slider 133 slides inside the track 131, thereby reducing the height between the two partitions 12.

[0048] When it is necessary to adjust the size of the two spaces separated by the partition 20, first, hold the handle 2353 tightly and pull it toward the side away from the slide rod 142. During this process, the elastic member 232 will be deformed and elongated due to the force. Then, rotate the handle 2353 to make the rotating ball 2352 rotate inside the handle 2353, so that the handle 2353 and the adjustment frame 222 are in a vertical state. After that, the other fixing member 23 is processed in the same way. At this time, the H plate 21 can be pushed to adjust the position of the partition 20 horizontally so that the slide rod 142 is in the slide groove 1 41, and after the partition 20 is pushed to the specified position, the handle 2353 is rotated to make the rotating ball 2352 rotate inside the handle 2353, so that the handle 2353 and the adjustment frame 222 are restored to a horizontal state. At this time, with the help of the rebound force of the elastic member 232, the fixed column 234 will move toward the inner wall of the slide groove 141 and exert pressure on the inner wall of the slide groove 141, so that the end of the anti-slip pad 236 away from the fixed column 234 is close to the inner wall of the slide groove 141, and the position of the partition 20 is fixed, and the work of adjusting the space of the chromatography laboratory cabinet can be completed.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
