DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment one, by Figures 1-4 A protein purification instrument with replaceable components is provided, which comprises a purification instrument body 10, the inside of the purification instrument body 10 is uniformly provided with an installation groove 20, the upper and lower sides of the installation groove 20 are both provided with a positioning assembly 30, and the inside of the installation groove 20 is provided with a module assembly 40.

[0025] The positioning component 30 includes a sliding plate 31 and a toggle component 32. The bottom of the sliding plate 31 has an arc-shaped groove 33, and the upper part of the sliding plate 31 is provided with a buffer spring 34. The other end of the buffer spring 34 is connected to the inside of the mounting groove 20. The bottom of the sliding plate 31 is provided with insertion posts 35. When the device is in use, if the module component 40 inside the purifier body 10 needs to be installed, it can be inserted into the mounting groove 20. When the module component 40 is installed, the positioning component 30 can fix its position. When the module component 40 is installed, the position of the toggle component 32 can be adjusted, causing the sliding plate 31 to be pressed down by the rebound force of the buffer spring 34. The descent of the sliding plate 31 causes the insertion post 35 to descend, thereby inserting and fixing the module assembly 40. Two sets of positioning components 30 effectively fix the upper and lower sides of the module assembly 40, ensuring better positioning. When the module assembly 40 needs to be disassembled, it can be rotated by the actuating component 32. The rotation of the actuating component 32 supports the sliding plate 31, allowing the insertion post 35 to disengage from the module assembly 40 for easier disassembly. The actuating component 32 includes a rotating bolt 320, the rear of which penetrates the purifier body 10 and is connected to an actuating block 321. The actuating block 321 is teardrop-shaped. When the actuating assembly 32 is in operation, the position of the actuating block 321 can be adjusted by rotating the pivot 320, allowing for better position adjustment. The teardrop-shaped actuating block 321 supports the sliding plate 31 during position adjustment. A baffle 41 is provided on the front of the module assembly 40, and positioning holes 42 are provided on both the upper and lower sides of the module assembly 40. A sealing gasket 43 is provided on the rear side of the baffle 41. The positioning holes 42 better limit the position of the positioning holes 42 when the insertion post 35 moves inward, thus ensuring better alignment of the module assembly 40 after installation. The mounting slots 20 are equipped with track grooves 21 on their front sides. The positioning component 30 is located inside the track grooves 21. The track grooves 21 effectively limit the position of the positioning component 30, allowing it to move more effectively and preventing positional deviation during lifting and lowering. The front side of the purification instrument body 10 has evenly spaced recesses 11 that mate with the front side of the module component 40.The recessed groove 11 allows for the placement of the front side of the module assembly 40 and the positioning of the baffle 41, facilitating better placement of the module assembly 40. A spring 22 is installed inside the mounting groove 20, with a push plate 23 at the other end. The push plate 23 is slidably connected inside the mounting groove 20. The spring 22 allows the push plate 23 to spring back, ensuring that the module assembly 40 automatically pops out during disassembly.

[0026] Working Principle: When the device is in use, if the module component 40 inside the purifier body 10 needs to be installed, it can be inserted into the mounting slot 20. During installation, the positioning component 30 can fix the position of the module component 40. When the module component 40 is installed, the position of the toggle component 32 can be adjusted so that the sliding plate 31 is pressed down by the rebound force of the buffer spring 34. The descent of the sliding plate 31 drives the insertion post 35 to descend, thus inserting and fixing the module component 40. With two sets of positioning components 30, the upper and lower sides of the module component 40 can be effectively fixed by insertion, making the module component 40 better positioned. When the module component 40 needs to be disassembled, the toggle component 32 can be rotated. The rotation of the toggle component 32 supports the sliding plate 31, thereby causing the insertion post 35 to disengage from the module component 40, making the module component 40 easier to disassemble.
