Description

Technical Field

[0001] The utility model relates to the technical field of chromatography equipment, in particular to a chromatography device for efficient and rapid detection. Background Technique

[0002] Chromatography is short for "chromatographic analysis". It is a method for separating and determining multi-component mixtures by using the different physical properties of each component. There are two types: adsorption chromatography and partition chromatography. It is generally used for the analysis of organic compounds, metal ions, amino acids, etc. Chromatography is a technique that uses the different distribution ratios of substances between the stationary phase and the mobile phase to achieve the separation purpose.

[0003] Application No. 201920995403.2 discloses an efficient chromatography separation device for experiments, including a base. A support column is fixed on the top of the base. Two sliding sleeves are sleeved on the outer wall of the support column. A fastening bolt is arranged on one side of the sliding sleeve. A connecting rod is arranged on the other side of the sliding sleeve. One end of the connecting rod is provided with a clamp. A number of chromatography tubes are clamped inside the clamp. A top cover is arranged on the top of the number of chromatography tubes. A liquid inlet hopper and a connecting pipe are arranged on the top of the top cover. A guiding pipe is arranged at the bottom of the number of chromatography tubes. Threaded pipes are arranged at the top of the guiding pipe and the chromatography tubes. A pressurizing device is arranged on the top of the base. By pressing the push rod on the pressurizing device of the utility model, the pressure inside the chromatography tube can be increased, so that the liquid to be chromatographically separated in the chromatography tube can quickly pass through the gel beads for separation, making the chromatography separation device work more efficiently and improving the efficiency of the experimenter in performing chromatography separation.

[0004] The above scheme has deficiencies in use. The clamping of the top and bottom of the chromatography tube cannot be completed, thus prolonging the fixing time of the chromatography tube and affecting the detection speed. For this reason, we propose a chromatography device for efficient and rapid detection to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0019] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , in the present utility model, a chromatography device for efficient and rapid detection includes a bottom plate 1. Above the bottom plate 1, a chromatography tube 7 is provided. The top end of the chromatography tube 7 is communicated with a feed hopper 6. A cover body is provided at the top of the feed hopper 6. The feed hopper 6 facilitates the staff to add test samples into the chromatography tube 7, and can also seal the feed hopper 6 to prevent foreign matters from falling in.

[0022] Two support plates 3 are fixedly connected to the outer surface of the chromatography tube 7. A slot 17 is opened at the bottom surface of each support plate 3. The top end of each top plate 2 is inserted into each slot 17, and the bottom end of each top plate 2 is connected to the upper surface of the bottom plate 1. When placing the chromatography tube 7, the slot 17 on the support plate 3 can be connected to the top end of the top plate 2, so as to form a preliminary stability for the chromatography tube 7.

[0023] A collection cup 12 is provided below the chromatography tube 7. The bottom surface of the collection cup 12 is in contact with the upper surface of the bottom plate 1. The collection cup 12 can collect the liquid flowing out of the chromatography tube 7.

[0024] The upper surface of the bottom plate 1 is fixedly connected with a first vertical plate 4. Two support columns 5 are fixedly connected to the right side surface of the first vertical plate 4. The upper surface of the bottom plate 1 is fixedly connected with a second vertical plate 11. A threaded hole 16 is formed in the right side surface of the second vertical plate 11. A threaded rod 9 is threadedly connected to the inner wall of the threaded hole 16. The right end of the threaded rod 9 is fixedly connected with a turning handle 15. Anti-slip threads are formed on the outer surface of the turning handle 15, and the provided turning handle 15 facilitates the staff to rotate the threaded rod 9.

[0025] The left end of the threaded rod 9 is fixedly connected with a moving plate 8. The left end of the threaded rod 9 is rotatably connected to the right side surface of the moving plate 8. The top end and the bottom end of the moving plate 8 are both fixedly connected with sliding columns 10. The left ends of the two sliding columns 10 and the right ends of the two support columns 5 are jointly fixedly connected with an arc-shaped plate 14. When the threaded rod 9 rotates, the moving plate 8 will push the sliding columns 10 to move synchronously, so that the arc-shaped plate 14 will clamp the bottom and the bottom of the chromatography tube 7.

[0026] Two sliding holes 13 are formed in the right side surface of the second vertical plate 11. The right end of each sliding column 10 penetrates through the sliding hole 13 and extends to the right side of the second vertical plate 11. The provided sliding holes 13 can stabilize the sliding columns 10 and ensure the stable movement of the moving plate 8.

[0027] The working principle of the present utility model is as follows: When the chromatography tube 7 needs to be replaced, the threaded rod 9 is rotated by using the turning handle 15. The threaded rod 9 will drive the moving plate 8 to move. The moving plate 8 will pull the sliding columns 10 to gradually slide out of the sliding holes 13. Correspondingly, the arc-shaped plate 14 will be separated from the chromatography tube 7. When fixing, only the bottom slot 17 of the support plate 3 on the chromatography tube 7 needs to be inserted onto the top plate 2, and then the threaded rod 9 is rotated in the reverse direction. The moving plate 8 will push the sliding columns 10, and the arc-shaped plate 14 will be attached to the chromatography tube 7, thus achieving the stability of the top and bottom of the chromatography tube 7, reducing the fixing time of the chromatography tube 7, and being able to accelerate the detection speed.
