Description

Technical Field

[0001] This utility model relates to the field of column loading machine technology, specifically a modularly assembled spring column loading device. Background Technology

[0002] Spring-loaded column packing equipment is a specialized device for efficiently and precisely packing chromatographic columns (such as HPLC and UPLC columns). Through spring-assisted mechanical pressure or a hydraulic system, the stationary phase packing material (such as silica gel, C18, etc.) is uniformly and tightly packed into the column tube, ensuring a stable and void-free column bed, thereby improving the efficiency and reproducibility of chromatographic separation. This equipment typically features pressure regulation, automatic packing, and online monitoring functions, and is suitable for high-precision chromatographic column preparation in laboratories or industrial production, especially in scenarios with stringent requirements for packing pressure, packing material uniformity, and column efficiency consistency.

[0003] The prior art patent application (application number 201922493444.4) entitled "A Spring-Loaded Column Device" includes a hollow column. The column has flanges at its upper and lower parts, a piston inside the column, a positioning shaft at its upper end, and a spring fitted onto the positioning shaft. The lower end of the positioning shaft is connected to the piston, and the upper end of the positioning shaft has an inlet pipe that passes through the center of the flanges, the positioning shaft, and the piston. The lower end of the column has an outlet pipe. This invention has a simple structure, facilitates column loading, and has high loading efficiency. However, the assembly of the column loading device is achieved through a flange structure, requiring rotation of the flanges to connect them to the column threadedly. This rotation process is time-consuming, affecting loading efficiency. Furthermore, since there is no sealing structure at the connection between the flanges and the column, the stationary phase packing material (such as silica gel or C18) inside the column may leak from the gaps during high-pressure loading, causing waste of packing material and affecting the uniformity of column packing and final column efficiency. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modularly assembled spring column mounting device, comprising a column body, both ends of which are provided with sealing grooves and inclined grooves, with two slots on one side of each inclined groove, and sealing caps snapped into both ends of the column body, and eight mounting plates provided on the outer side of the column body, with four inner mounting plates fixedly connected to the column body and the four outer mounting plates fixedly connected to the sealing caps.

[0006] Preferably, a through pipe is fixedly connected to one side of the sealing cover, and two sealing rings are fixedly connected to one side of the sealing cover. The sealing rings cooperate with the sealing groove to seal the gap at the connection between the sealing cover and the column.

[0007] Preferably, the sealing ring extends to the inner side of the sealing groove, and the sealing ring fits into the sealing groove, thereby sealing the gap at the connection between the sealing cover and the column through the cooperation of the sealing ring and the sealing groove.

[0008] Preferably, a mating groove is provided on one side of the sealing cover, the mating groove is fitted with the inclined groove, and two retaining rings are fixedly connected to one side of the mating groove. The retaining rings extend to the inside of the retaining groove and are fitted with the retaining groove. The gap at the connection between the sealing cover and the column is sealed by the retaining rings cooperating with the retaining groove.

[0009] Preferably, a docking compartment is fixedly connected to one side of the inner mounting plate, and a first adsorption magnet is fixedly connected to the inner cavity of the docking compartment, so that the first adsorption magnet and a second adsorption magnet can be adsorbed together.

[0010] Preferably, the docking compartment has an annular groove inside and a through groove on one side, and the locking rod is limited by the annular groove.

[0011] Preferably, a mounting base is fixedly connected to one side of the outer mounting plate, and a rotating rod is movably connected to the inner side of the mounting base. One end of the rotating rod extends into the inner cavity of the docking compartment, and a second adsorption magnet is fixedly connected to one end of the rotating rod. The second adsorption magnet is adsorbed and connected to the first adsorption magnet. Two locking rods are fixedly connected to the outer side of the rotating rod. The locking rods are located inside the annular groove. By locking the rods inside the annular groove, the rotating rod connected to the locking rods is limited, preventing the rotating rod from moving longitudinally.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This modularly assembled spring column mounting equipment, through a modular installation mechanism, allows for the quick and easy installation of the sealing cover onto the column body during assembly, thus facilitating the installation and fixation of the sealing cover and enabling the rapid and convenient completion of the assembly work of the spring column mounting equipment.

[0014] 2. This modularly assembled spring column loading equipment, through a sealing mechanism, can perform multiple seals on the gaps at the connection between the sealing cover and the column body, preventing the fixed phase filler inside the column from leaking out of the gaps during high-pressure loading, thereby effectively improving the sealing performance of the spring column loading equipment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4This utility model provides a modularly assembled spring column mounting device, including a column body 100. Both ends of the column body 100 have sealing grooves 110 and inclined grooves 120. Two slots 121 are formed on one side of each inclined groove 120. Sealing caps 130 are snapped onto both ends of the column body 100. A through pipe 131 is fixedly connected to one side of each sealing cap 130. Two sealing rings 140 are fixedly connected to one side of each sealing cap 130, extending into the inner side of the sealing groove 110 and fitting against it. A docking groove 150 is formed on one side of each sealing cap 130, fitting against the inclined groove 120. Two retaining rings 151 are fixedly connected to one side of each docking groove 150, extending into the inner side of the retaining groove 121 and fitting against it.

[0022] Specifically, by installing the sealing cap 130 onto the column 100, and then moving the rotating rod 250 inside the mounting base 240 on the mounting plate 200 on the sealing cap 130 through the through groove 230 in the docking chamber 210, the second adsorption magnet 251 at the bottom of the rotating rod 250 is attracted to the first adsorption magnet 211 in the docking chamber 210. Afterwards, by rotating the rotating rod 250, the locking rod 260 on the rotating rod 250 moves from below the through groove 230 to the annular groove. Within 220, the annular groove 220 engages with the locking rod 260 to limit the rotation rod 250, preventing it from moving longitudinally and thus securing the sealing cover 130. When disassembling the sealing cover 130, rotating the rotation rod 250 moves the locking rod 260 from the inside of the annular groove 220 to below the through groove 230. Then, pulling the sealing cover 130 allows the mounting rod to pass through the through groove 230 and exit the docking chamber 210, completing the disassembly of the sealing cover 130.

[0023] Example 2: Please refer to again Figure 1-4 The outer side of the column 100 is provided with eight mounting plates 200, and the four inner mounting plates 200 are fixedly connected to the column 100. The four outer mounting plates 200 are fixedly connected to the sealing cover 130. A docking chamber 210 is fixedly connected to one side of the inner mounting plate 200. A first adsorption magnet 211 is fixedly connected to the inner cavity of the docking chamber 210. An annular groove 220 is opened inside the docking chamber 210. A through groove 230 is opened on one side of the docking chamber 210. A mounting base 240 is fixedly connected to one side of the outer mounting plate 200. A rotating rod 250 is movably connected to the inner side of the mounting base 240. One end of the rotating rod 250 extends into the inner cavity of the docking chamber 210, and a second adsorption magnet 251 is fixedly connected to one end of the rotating rod 250. The second adsorption magnet 251 is adsorbed and connected to the first adsorption magnet 211. Two locking rods 260 are fixedly connected to the outer side of the rotating rod 250. The locking rods 260 are located inside the annular groove 220.

[0024] Specifically, after the sealing cover 130 is installed on the column 100, the sealing ring 140 on the sealing cover 130 moves into the sealing groove 110 in the column 100, so that the sealing ring 140 and the sealing groove 110 cooperate to form a multiple sealing barrier, sealing the gap at the connection between the sealing cover 130 and the column 100. At the same time, the mating groove 150 on the sealing cover 130 will also fit with the inclined groove 120 on the column 100 to form an inclined seal. Furthermore, the retaining ring 151 installed on the mating groove 150 extends into the retaining groove 121 on the inclined groove 120, so that the retaining ring 151 and the retaining groove 121 cooperate to form a multiple sealing barrier, sealing the gap at the connection between the sealing cover 130 and the column 100.

[0025] Working principle: By installing the sealing cover 130 onto the column 100, the rotating rod 250, which is then installed on the mounting plate 200 on the sealing cover 130, moves into the docking chamber 210 through the through groove 230. This causes the second adsorption magnet 251 at the bottom of the rotating rod 250 to adsorb with the first adsorption magnet 211 in the docking chamber 210. Then, by rotating the rotating rod 250, the locking lever 260 on the rotating rod 250 moves from below the through groove 230 to the annular position. Inside the groove 220, the annular groove 220 and the locking rod 260 cooperate to limit the rotating rod 250, preventing the rotating rod 250 from moving longitudinally, thus fixing the sealing cover 130. When disassembling the sealing cover 130, the locking rod 260 on the rotating rod 250 is moved from the inside of the annular groove 220 to below the through groove 230 by rotating the rotating rod 250. Then, the sealing cover 130 is pulled to allow the installation rod to move out of the docking chamber 210 through the through groove 230, thus completing the disassembly of the sealing cover 130.

[0026] After the sealing cap 130 is installed on the column 100, the sealing ring 140 on the sealing cap 130 moves into the sealing groove 110 in the column 100, so that the sealing ring 140 and the sealing groove 110 cooperate to form a multiple sealing barrier, sealing the gap at the connection between the sealing cap 130 and the column 100. At the same time, the mating groove 150 on the sealing cap 130 will also fit with the inclined groove 120 on the column 100 to form an inclined seal. Furthermore, the retaining ring 151 installed on the mating groove 150 extends into the retaining groove 121 on the inclined groove 120, so that the retaining ring 151 and the retaining groove 121 cooperate to form a multiple sealing barrier, sealing the gap at the connection between the sealing cap 130 and the column 100.
