Description

Technical Field

[0001] This utility model relates to the field of chromatography column support technology, and in particular to a perfluorinated chromatography column support. Background Technology

[0002] Chromatography is widely used as an important separation and analysis technique in many fields such as modern chemistry, biopharmaceuticals, and environmental monitoring. Perfluorinated chromatography columns, due to their special chemical properties, have shown unique advantages in separating substances that have special requirements for conventional chromatography columns, and are therefore increasingly favored by researchers and manufacturing companies.

[0003] However, in the actual use of perfluorinated chromatography columns, there are many shortcomings in the methods of supporting and fixing them. Traditional chromatography column support devices are often simple in structure and single in function. In terms of height adjustment, many support devices can only provide a limited number of fixed height options, which cannot meet the precise requirements of chromatography column height under different experimental platform heights, different operator habits, and complex experimental setups. This may result in the chromatography column being positioned too high or too low in actual operation, causing inconvenience to the operator and even affecting the accuracy and efficiency of the experimental operation.

[0004] In terms of angle adjustment, traditional support devices are even more lacking. In some experiments or production processes, chromatography columns need to be placed at a specific angle to ensure separation effect or facilitate liquid flow, but existing support devices are difficult to achieve flexible multi-angle adjustment, which limits the application of perfluorinated chromatography columns in these special scenarios.

[0005] In addition, the structural design of traditional support devices is often unreasonable, the installation and disassembly process is cumbersome, requires professional tools and skills, and consumes a lot of time and manpower. Moreover, when a component is damaged or the size is not right, the replacement operation will be very inconvenient.

[0006] In summary, existing perfluorinated chromatography column support methods are insufficient to meet the growing experimental and production demands, making the development of a novel, efficient, and multifunctional perfluorinated chromatography column support urgent. Utility Model Content

[0007] One objective of this invention is to propose a perfluorinated chromatography column support bracket. This invention allows for flexible and precise adjustment of height and angle to adapt to different experimental scenarios and operational needs, effectively solving the problem of limited height and angle adjustment in traditional support devices. Furthermore, through the design of retractable and replaceable components, it can accommodate chromatography columns of different lengths and facilitate replacement when components are damaged, effectively controlling maintenance costs, extending the overall service life of the bracket, and comprehensively meeting the diverse needs of modern scientific research and production for perfluorinated chromatography column support.

[0008] According to an embodiment of the present invention, a perfluorinated chromatography column support includes a base, an adjusting seat, a support ring, and a clamping ring.

[0009] A support rod is fixedly installed on one side of the top of the base. There are two sets of adjustment seats, and both sets of adjustment seats are fitted onto the support rod. An annular groove is opened at the bottom of the adjustment seat. An annular slider is rotatably installed in the annular groove. An adjustment knob is fixedly installed at the bottom of the annular slider. An external thread is opened on the outer wall of the support rod. A threaded hole is opened through the adjustment knob. The external thread and the internal thread on the inner wall of the threaded hole mesh with each other.

[0010] A movable ring is rotatably fitted on the adjusting seat. A sleeve rod is integrally formed on one side of the outer wall of the movable ring. An inner rod is telescopically installed inside the sleeve rod. A T-shaped slot is opened at the outer end of the inner rod. A T-shaped insert is provided on one side of the support ring and the clamping ring. The support ring and the clamping ring can be fixedly connected to the inner rod by inserting the T-shaped insert into the T-shaped slot.

[0011] Furthermore, symmetrical limit grooves are formed on the outer walls of both sides of the support rod, and limit blocks are integrally formed on both sides of the inner wall of the adjusting seat, with the limit blocks slidably installed in the limit grooves.

[0012] Furthermore, a first screw hole is provided through the other side of the movable ring, and a first fastening bolt is screwed into the first screw hole.

[0013] Furthermore, a second threaded hole is provided through one side of the top of the sleeve rod, and a second fastening bolt is screwed into the second threaded hole.

[0014] Furthermore, the inner surface of the support ring is provided with an anti-slip rubber pad to increase the friction between the support ring and the chromatography column and prevent the chromatography column from sliding on the support ring.

[0015] Furthermore, the clamping ring consists of two sets of arc-shaped clamping pieces. The inner diameter of the clamping ring is smaller than the outer diameter of the chromatography column. The chromatography column can be clamped and fixed by the clamping ring, and a buffer layer is provided on the inner side of the clamping ring to prevent the clamping ring from damaging the surface of the chromatography column.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, by rotating the adjustment knob and utilizing the engagement of the external thread and the threaded hole, the height of the adjustment seat on the support rod can be precisely adjusted. At the same time, the movable ring can rotate on the adjustment seat, and with the first fastening bolt, it can be fixed in any desired position. This flexible height and position adjustment design can meet the diverse requirements for the placement of the perfluorinated chromatography column under different experimental scenarios and operational needs. Whether in a small laboratory bench or in the layout of large equipment in industrial production, the most suitable support angle and height of the chromatography column can be easily found, greatly improving the versatility and adaptability of the support.

[0018] 2. In this utility model, the inner rod inside the sleeve can be telescopically installed and the extended length is fixed by the second fastening bolt. This design allows the support to adapt to chromatography columns of different sizes. The support ring and clamping ring are connected to the T-shaped slot on the inner rod by the T-shaped insert, making the installation process easy and convenient. When the support ring, clamping ring or other parts are damaged, they can be easily and quickly replaced individually due to the standardized connection method. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please see Figure 1-5 The perfluorinated chromatography column support includes a base 1, an adjusting seat 5, a support ring 9, and a clamping ring 10;

[0028] The support rod 2 is firmly fixed to one side of the top of the base 1. There are two sets of adjusting seats 5, both of which are fitted onto the support rod 2. The bottom of the adjusting seat 5 is provided with an annular groove 15, and an annular slider 17 is flexibly installed in the annular groove 15. The bottom of the annular slider 17 is fixedly connected to the adjusting knob 6. The outer wall of the support rod 2 is machined with external threads 4, and the adjusting knob 6 has a through threaded hole 16. The external threads 4 and the internal threads on the inner wall of the threaded hole 16 are matched and engaged. By rotating the adjusting knob 6, the position of the adjusting seat 5 on the support rod 2 can be adjusted.

[0029] To ensure that the adjusting seat 5 slides stably on the support rod 2 and does not rotate arbitrarily, limit grooves 3 are symmetrically opened on the outer walls of both sides of the support rod 2, and limit blocks 14 are integrally formed on both sides of the inner wall of the adjusting seat 5. The limit blocks 14 can slide smoothly in the limit grooves 3.

[0030] In this embodiment, rotating the adjustment knob 6 clockwise will cause the adjustment seat 5 to rise on the support rod 2. Conversely, rotating the adjustment knob 6 counterclockwise will cause the adjustment seat 5 to fall. This allows for adjustment of the distance and height between the two sets of adjustment seats 5 according to the actual usage scenario, ensuring applicability. The adjustment operation is simple, time-saving, and labor-saving.

[0031] Please see Figure 1-5A movable ring 7 is rotatably fitted onto the adjusting seat 5. One outer wall of the movable ring 7 is integrally formed with the sleeve rod 8. An inner rod 11 is telescopically installed inside the sleeve rod 8. A T-shaped slot 12 is provided at the outer end of the inner rod 11. A T-shaped insert 13 is provided on one side of the support ring 9 and the clamping ring 10. The support ring 9 and the clamping ring 10 can be securely connected to the inner rod 11 by inserting the T-shaped insert 13 into the T-shaped slot 12. To fix the position of the movable ring 7 on the adjusting seat 5, a first screw hole 18 is provided through the other side of the movable ring 7. A first fastening bolt 19 is screwed into the first screw hole 18. Similarly, to fix the extension length of the inner rod 11 inside the sleeve rod 8, a second screw hole 20 is provided through the top side of the sleeve rod 8. A second fastening bolt 21 is screwed into the second screw hole 20.

[0032] Secondly, the inner surface of the support ring 9 is covered with an anti-slip rubber pad. This design greatly increases the friction between the support ring 9 and the chromatography column, effectively preventing the chromatography column from sliding on the support ring 9. The clamping ring 10 consists of two sets of arc-shaped clamping pieces. The inner diameter of the clamping ring 10 is slightly smaller than the outer diameter of the chromatography column. The clamping ring 10 can firmly clamp and fix the chromatography column. In addition, a buffer layer is provided on the inner side of the clamping ring 10 to prevent the clamping ring 10 from damaging the surface of the chromatography column during the clamping process.

[0033] In this embodiment, the length can be adjusted by extending or retracting the inner rod 11, and the angle between the sleeve rod 8 and the inner rod 11 can be adjusted by rotating the movable ring 7. Thus, the angle and the alignment of the upper and lower clamping rings 10 and the support ring 9 can be conveniently and flexibly adjusted according to the actual situation.

[0034] Working principle: When a support bracket for a perfluorinated chromatography column is required, firstly, based on the height of the chromatography column, rotate the adjusting knob 6. Using the threaded engagement, the adjusting seat 5 is raised or lowered along the support rod 2 to the appropriate position. The engagement of the limiting block 14 and the limiting groove 3 ensures that the adjusting seat 5 will not rotate, only move linearly. After the position is determined, rotate the movable ring 7 to the appropriate angle, and then tighten the first fastening bolt 19 to press it against the adjusting seat 5, thereby fixing the angle of the movable ring 7. Next, according to the specific placement requirements of the chromatography column, adjust the extension length of the inner rod 11 within the sleeve rod 8. After it is in place, tighten the second fastening bolt 21. To fix the inner rod 11, if a chromatography column needs to be placed, the support ring 9 can be inserted into the T-slot 12 through the T-shaped insert 13 and installed on the inner rod 11. The anti-slip rubber pad on the inner ring of the support ring 9 supports the bottom of the chromatography column to prevent it from sliding. If a more stable fixation of the chromatography column is required, the clamping ring 10 can be installed on the inner rod 11 through the T-shaped insert 13. Since the inner diameter of the clamping ring 10 is smaller than the outer diameter of the chromatography column, after it is placed in the appropriate position on the chromatography column, the chromatography column can be clamped. The inner buffer layer protects the surface of the chromatography column from being damaged by the clamping. Through the above series of operations, the perfluorinated chromatography column can be stably supported and fixed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
