Description

Technical Field

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

[0002] In column chromatography experiments, column fixation is one of the key steps to ensure the success of the experiment.

[0003] Currently, common fixation methods typically rely on separate iron stands, clamps, or butterfly clamps. While these tools can meet basic experimental needs to some extent, in practice, each chromatography column needs to be clamped and fixed individually. This not only increases the complexity and time consumption of the experiment but also easily leads to errors during installation and fixation. Especially when conducting multi-sample experiments, this cumbersome installation and fixation process significantly increases the labor intensity and reduces experimental efficiency.

[0004] To address the aforementioned issues, a chromatography column support is now designed. Utility Model Content

[0005] This application provides a chromatography column support to solve the problem in related technologies where it is inconvenient to use separate iron stands, iron clamps, or butterfly clamps to hold and fix chromatography columns in actual column chromatography experiments.

[0006] In a first aspect, a chromatography column support is provided, comprising:

[0007] The base has a support column rotatably mounted on it. Two positioning plates are positioned opposite each other above the support column. The positioning plates are provided with a number of positioning grooves for accommodating the chromatography column tubes. The positioning grooves on the upper and lower sides correspond one to one.

[0008] The positioning groove is provided with a clamping member, which is used to clamp the chromatography column tube inside the positioning groove.

[0009] In some embodiments, the base includes a chassis and support legs arranged in a ring shape below the chassis.

[0010] In some embodiments, the support includes interconnected rods and a disc, and the chassis has an internal mounting groove for accommodating the disc, the disc being rotatably mounted within the mounting groove.

[0011] In some embodiments, the positioning disk is inserted into the rod body, and the rod body has a plurality of insertion holes, wherein a support rod for supporting the positioning disk is inserted into two of the insertion holes.

[0012] In some embodiments, the top end of the rod is threaded, and an installation cylinder is threadedly connected to the top end of the rod.

[0013] In some embodiments, the clamping member includes a telescopic groove that is opened opposite to the positioning groove, a clamping piece that is slidably disposed inside the telescopic groove, the clamping piece being arc-shaped, and a plurality of springs disposed inside the telescopic groove, one end of each spring being connected to the clamping piece to provide elastic support for the clamping piece.

[0014] This application provides a chromatography column holder that, through the cooperation of positioning grooves on the upper and lower positioning plates and clamping components, ensures the stability of the chromatography column during experiments, preventing experimental failures due to shaking or detachment. It also simplifies and speeds up experimental operations. Operators can easily install and remove the chromatography column without the need for additional fixing tools or equipment.

[0015] By adjusting the rotation angle of the column, researchers can flexibly adjust different chromatography columns to adapt to different experimental needs and conditions. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application provides a chromatography column support that solves the problem in related technologies where it is inconvenient to use separate iron stands, iron clamps, or butterfly clamps to hold and fix chromatography columns in actual column chromatography experiments.

[0025] Please see Figures 1-5 A chromatography column support includes a base 1, on which a support column 2 is rotatably mounted. Two positioning disks 4 are positioned opposite each other above the support column 2. Each positioning disk 4 has a plurality of positioning grooves 5 for accommodating the chromatography column body, with the positioning grooves 5 on the upper and lower sides corresponding one-to-one. A clamping member 6 is provided inside the positioning groove 5 for clamping the chromatography column body inside the positioning groove 5.

[0026] The experimenters first selected a chromatography column of appropriate size and aligned its tube body with the corresponding positioning slots 5 on the upper positioning plate 4 and the lower positioning plate 4, respectively.

[0027] After the chromatography column is inserted into the positioning groove 5, the clamping member 6 inside the positioning groove 5 will automatically adapt to the diameter of the chromatography column and generate a certain clamping force to ensure that the chromatography column will not shake or fall off in the vertical direction.

[0028] The support column 2 and the base 1 are rotatably connected, which allows the experimenter to adjust the angle of the support column 2 and replace different chromatography columns according to the experimental requirements.

[0029] After the experiment, the experimenters can easily remove the chromatography column from the positioning slots 5 of the upper and lower positioning plates 4 for disassembly and cleaning.

[0030] The positioning grooves 5 on the upper and lower positioning plates 4, in conjunction with the clamping parts 6, ensure the stability of the chromatography column during the experiment, preventing experimental failures due to shaking or detachment. This also simplifies and speeds up the experimental operation. Operators can easily install and remove the chromatography column without the need for additional fixing tools or equipment.

[0031] By adjusting the rotation angle of column 2, researchers can flexibly adjust different chromatography columns to adapt to different experimental needs and conditions.

[0032] The support's modular design makes disassembly and cleaning simple and convenient. Researchers can easily disassemble each component for cleaning and maintenance, extending the support's lifespan.

[0033] Specifically, the base 1 includes a chassis 11 and support legs 12 arranged in a ring below the chassis 11.

[0034] The base 1, as an important component of the chromatography column support, has the main function of providing stable support to ensure that the entire support and the chromatography column installed on it can stand stably on the experimental table.

[0035] The base 11, as the main body of the base 1, is typically made of sturdy and durable materials, such as metal or high-strength plastic, to ensure it can withstand the weight of the support and the chromatography column above it. The support legs 12 are arranged in a ring below the base 11, increasing the contact area between the base 1 and the experimental table surface, thereby improving the stability of the support.

[0036] In one embodiment, the positioning disk 4 is inserted into the rod body 21, and the rod body 21 has a plurality of insertion holes 23, wherein a support rod 24 for supporting the positioning disk 4 is inserted into two of the insertion holes 23.

[0037] The rod 21, as the main load-bearing part of the support column 2, is responsible for connecting the chassis 11 and the positioning plate 4, and supporting the weight of the entire bracket.

[0038] The disc 22 is connected to the rod 21 and is usually located at the bottom of the rod 21, so that it can be rotatably mounted in the mounting groove inside the chassis 11.

[0039] The chassis 11 has an internal mounting slot for accommodating the disc 22. The shape and size of this mounting slot match the disc 22, ensuring that the disc 22 can rotate stably within it.

[0040] When the experimenter needs to adjust the angle of the positioning disk 4, this can be achieved by rotating the support column 2. Since the disk 22 is rotatably set within the mounting slot, the support column 2 can rotate freely relative to the base 11, thereby causing the positioning disk 4 above to rotate as well.

[0041] By adjusting the position of the support rod 24 in the corresponding insertion hole 23, the height of the positioning disk 4 on the rod body 21 and the relative position of the two positioning disks 4 can be adjusted, thereby improving the flexibility of the equipment and adapting it to different types of chromatography columns.

[0042] Preferably, in this embodiment, the top end of the rod 21 is threaded, and the top end of the rod 21 is threadedly connected to the mounting cylinder 3.

[0043] The thread at the top of the rod 21 allows for a tight connection between the rod 21 and the mounting sleeve 3 through rotation and tightening. When the mounting sleeve 3 rotates and fits onto the top of the rod 21, the threads of the two engage to form a secure connection.

[0044] In practice, the positioning plate 4 can be easily disassembled and maintained by removing the mounting cylinder 3.

[0045] In a preferred embodiment, the clamping member 6 includes a telescopic groove 61 that is opened opposite to the positioning groove 5. A clamping piece 62 is slidably disposed inside the telescopic groove 61. The clamping piece 62 is arc-shaped. A plurality of springs 63 are disposed inside the telescopic groove 61. One end of each spring 63 is connected to the clamping piece 62 to provide elastic support for the clamping piece 62.

[0046] The telescopic groove 61 provides space for the clip 62 to slide. The shape and size of the telescopic groove 61 match the clip 62 to ensure that the clip 62 can slide smoothly within it.

[0047] The clip 62 is arc-shaped and is used to fit tightly against the outer wall of the chromatography column. The inner surface of the clip 62 is provided with anti-slip texture or protrusions to increase the friction between it and the chromatography column and prevent the column from slipping during the experiment.

[0048] Spring 63 is disposed inside telescopic groove 61, with one end connected to clamp 62. Spring 63 provides elastic support for clamp 62, enabling it to automatically adapt to chromatography column tubes of different diameters and maintain a certain clamping force.

[0049] When the chromatography column is inserted into the positioning groove 5, it compresses the clamping piece 62, causing it to slide inward within the telescopic groove 61 and compress the spring 63. As the spring 63 is compressed, the clamping piece 62 applies increasing clamping force to the chromatography column until its inner surface is tightly fitted against the outer wall of the column. Due to the elasticity of the spring 63, the clamping piece 62 can automatically adapt to chromatography columns of different diameters and maintain a stable clamping state.
