[0002] Chromatography, short for "chromatographic analysis", is an important way of material transfer and separation technology. The device used for chromatography experiments is a chromatography device, which is a high-efficiency chemical separation tool designed based on the principle of chemical affinity differences. It is widely used in medicine, life sciences, chemistry, environmental protection and other fields. Its basic principle is to utilize the differences between different substances in the stationary phase and the mobile phase to separate and purify the target substance. The basic components of the chromatography device include the stationary phase, mobile phase, column and detector.

In addition, the thread needs to be twisted continuously, and the staff needs to hold the cross bar continuously for positioning. Over time, it is easy to cause hand fatigue and inconvenience for the staff to operate. Therefore, a chromatography device that is easy to operate is proposed to address the above problems.

[0032] A vertical pole 2, wherein the vertical pole 2 is mounted on the surface of the base 1, and the sliding assembly is slidably connected on the surface of the vertical pole 2;

[0033] The sliding assembly includes a slider 3, a crossbar 6 is fixedly connected to the surface of the slider 3, and a clamping assembly is fixedly connected to the end of the crossbar 6;

[0034] The surface of the slider 3 is fixedly connected with a fixed shaft 11, and the surface of the fixed shaft 11 is slidably connected with a sliding shaft 18 through a spring, both ends of the sliding shaft 18 pass through the fixed shaft 11, and one end of the fixed shaft 11 is fixedly connected with a clamping rod 9, and the clamping rod 9 is "L"-shaped, and the short arm end of the clamping rod 9 passes through the side wall of the slider 3 for sliding connection. A rectangular groove 8 is opened on the surface of the vertical rod 2 relative to the position of the clamping rod 9, and a top block 7 is clamped on the top of the vertical rod 2;

[0035] When working, the beaker is first placed on the surface of the base 1, and then the sliding shaft 18 is slid so that the sliding shaft 18 moves in the fixed shaft 11, and at the same time, the clamping rod 9 is driven to disengage the rectangular groove 8 on the surface of the vertical rod 2, so that the clamping rod 9 releases the positioning of the slider 3, and then the slider 3 slides up and down on the surface of the vertical rod 2, and at the same time, the cross bar 6 is driven to slide up and down, so that the slide bar drives the clamping assembly to slide. After the slider 3 is positioned to a suitable position, the sliding shaft 18 is released, so that the clamping rod 9 is stuck in the rectangular groove 8, and then the chromatography column is clamped by the clamping assembly to perform chromatography reaction. The slider 3 can be positioned by the clamping rod 9 in conjunction with the rectangular groove 8, and the height of the cross bar 6 is positioned at the same time, avoiding the use of threads to position it, avoiding the situation that the threads are prone to rust after being used for a long time, thereby increasing the resistance generated during rotation, and the threads need to be twisted continuously, and the staff needs to continuously hold the cross bar for positioning, which can easily cause hand fatigue over time and is inconvenient for the staff to operate. At the same time, through the design of the detachable top block 7, the device can be disassembled for easy storage.

[0036] An arc plate 12 is fixedly connected to the surface of the fixed shaft 11, and two arc plates 12 are provided, and a pair of the arc plates 12 are symmetrically distributed with respect to the central axis of the fixed shaft 11. Anti-skid pads are bonded to the surfaces of the two arc plates 12. A card bead 19 is slidably connected to the fixed shaft 11 through a spring, and an arc groove 13 is provided on the surface of the vertical pole 2 relative to the position of the card bead 19. When working, the arc plate 12 can be used to better leverage the sliding shaft 18, and the anti-skid pad can increase the friction between the finger and the arc plate. The card bead 19 can generate a certain resistance when the slider 3 slides, and feedback can be given at the same time to facilitate the positioning of the vertical pole 2.

[0037] The cross section of the vertical rod 2 is rectangular, and the sliding assembly is provided with two, and is arranged up and down. The surface of the upper slider 3 is fixedly connected with a cross bar 2 6, and the surface of the lower slider 3 is fixedly connected with a cross bar 1 4. The end of the cross bar 1 4 is fixedly connected with a positioning assembly, and the positioning assembly includes a collar 17, and a rubber ring 16 is fixedly connected inside the collar 17, and the rubber ring 16 is hollow;

[0038] During operation, the vertical rod 2 with a rectangular cross-section can prevent the slider 3 from rotating when sliding, so that the centers of the two clamping plates 15 are coaxial with the ring 17. Through the hollow rubber ring 16 fixedly connected inside the ring 17, when the chromatography column is inserted into the ring 17, the column will squeeze the rubber ring 16, causing the rubber ring 16 to deform. At the same time, the internal gas will make the rubber ring 16 fit the surface of the chromatography column, so that the ring 17 can adapt to chromatography columns of different shapes.

[0039] The clamping assembly includes a transverse axis 14, which is fixedly connected to the surface of the second crossbar 6, and a notch 21 is provided on the surface of the transverse axis 14, and a pair of slide plates 20 are slidably connected to the notch 21 through a spring, and a clamping plate 15 is fixedly connected to one side of the slide plate 20, and the clamping plate 15 is "V"-shaped, and a rotating shaft 23 is rotatably connected to the two surfaces of the transverse axis 14, and a connecting rope 22 is fixedly connected between the pair of slide plates 20, and the other end of the connecting rope 22 is fixedly connected to the surface of the rotating shaft 23, and a paddle 25 is slidably connected to the surface of the second crossbar 6 through a spring, and a plug rod 24 is fixedly connected to one side of the paddle 25, and an oblique angle is provided on the surface of the plug rod 24, and a plurality of slots are provided on the surface of the rotating shaft 23 relative to the position of the plug rod 24, and the slots are equidistantly distributed;

[0040] When working, after the chromatography column is stuck in the ring 17, the rotating shaft 23 is rotated so that the rotating shaft 23 pulls the connecting rope 22 and winds the connecting rope 22 around the surface of the rotating shaft 23. At this time, the connecting rope 22 will pull the slide plate 20 to move in the direction of approaching each other and stretch the spring to generate elastic force. At the same time, the slide plate 20 will drive the two clamping plates 15 to move in the direction of approaching each other, so that the clamping plates 15 clamp the chromatography column. When the rotating shaft 23 rotates, the side wall of the slot on the surface of the rotating shaft 23 will squeeze the bevel of the surface of the plug rod 24, so that the plug rod 24 slides in the direction of the original sliding shaft 18. At the same time, the spring is squeezed to generate elastic force, and the rotating shaft 23 is positioned by the plug rod 24 cooperating with the slot, so as to further improve the fixing effect of the chromatography column. The "V"-shaped clamping plate 15 can cooperate with the rubber ring 16 in the ring 17 to clamp columns of different diameters. The positioning component cooperates with the clamping component to facilitate the fixing of the chromatography column, thereby improving the installation efficiency.
