[0022] like Figures 1 to 3As shown, the utility model proposes a plasma protein chromatography column storage rack, comprising: a rack body 1, a storage table 2, a partition mechanism 3, and a positioning mechanism 4. The storage table 2 is mounted on the rack body 1, and a partition mechanism 3 is provided on the storage table 2, and a positioning mechanism 4 is installed on the partition mechanism 3; the rack body 1 comprises: at least four support columns 11, the support columns 11 are placed vertically, and the four support columns 11 are connected to each other by connecting plates 12, and a storage table 2 is fixed on the top of the support columns 11, and the connecting plate 12 surrounds the storage table 2; the partition mechanism 3 comprises: a plurality of partition plates 31, the partition plates 31 are fixed on the storage table 2, and an insertion groove 32 is formed between two adjacent partition plates 31 or between a partition plate 31 and a connecting plate 12, and the insertion groove 32 is used to place The chromatography column body of the plasma protein chromatography column has a positioning mechanism 4 on one side of the partition plate 31, and the positioning mechanism 4 is used to position the infusion tube of the plasma protein chromatography column; the positioning mechanism 4 includes: a first positioning block 41, a second positioning block 42 and a sliding plate 43, the first positioning block 41 and the second positioning block 42 are L-shaped, and a positioning groove is formed between the first positioning block 41 and the second positioning block 42, and the sliding plate 43 can be inserted into the positioning groove. The sliding plate 43 can also slide relative to the first positioning block 41 and the second positioning block 42. A locking component 431 is also provided on the sliding plate 43, and the locking component 431 is used to position the infusion tube on the sliding plate 43. A shut-off component 432 is also provided on one end of the sliding plate 43, and the shut-off component 432 is used to block the infusion tube of the plasma protein chromatography column. During use, the liquid storage bottle is placed in the insertion slot 32 on the storage table 2, and the sliding plate 43 on the positioning mechanism 4 is not inserted into the positioning slot. The infusion tube is clamped into the locking assembly 431 on the sliding plate 43, and then the sliding plate 43 is pushed into the positioning slot for positioning, that is, the infusion tube is positioned on the partition plate 31. When the liquid storage bottle needs to be replaced, the flow-cutting assembly 432 stops the flow of plasma by pressing the infusion tube.

[0023] There are at least three locking components 431, and the locking components 431 are arranged in sequence along the X direction. The locking components 431 are used to guide the positioning direction of the infusion tube.

[0024] The locking assembly 431 includes an arcuate piece 4311 and a fixed piece 4312. The fixed piece 4312 is fixedly connected to the sliding plate 43. One end of the fixed piece 4312 is fixed to one end of the arcuate piece 4311. The other end of the arcuate piece 4311 and the other end of the fixed piece 4312 form a latching opening for the infusion tube to be latched into. A locking groove is formed between the fixed piece 4312 and the arcuate piece 4311. The locking groove is for the infusion tube to be inserted into. When the sliding plate 43 is inserted into the positioning groove, the first positioning block 41 is close to the side wall of the locking assembly 431 to block the latching opening. When the sliding plate 43 is pulled out of the positioning groove, the infusion tube is pushed from the latching opening into the locking groove. The sliding plate 43 is then pushed back into the positioning groove. The latching opening is blocked by the first positioning block 41, preventing the infusion tube from falling off the positioning mechanism 4.

[0025] The connecting plate 12 surrounds the storage table 2 to form a U-shaped structure. The connecting plate 12 forms a gap on one side of the storage table 2 , and the gap is opened and closed by a closing plate 5 .

[0026] One side of the closing plate 5 is hinged to the connecting plate 12, and the other side of the closing plate 5 is positioned on the support column 11 via a locking pin mechanism 6. The closing plate 5 prevents the sliding plate 43 from being disengaged from the positioning slot. When the sliding plate 43 needs to be pulled out of the positioning slot, the closing plate 5 can be opened. When the sliding plate 43 is pushed into the positioning slot, the closing plate 5 is closed to support the end of the sliding plate 43, preventing the sliding plate 43 from sliding within the positioning slot.

[0027] The locking mechanism 6 comprises a rotating pin 61 and a locking seat 62. The locking seat 62 is mounted on the support column 11 and has a locking gap. One end of the rotating pin 61 is rotatably mounted on the closing plate 5, and the locking gap allows the other end of the rotating pin 61 to be screwed into. When the rotating pin 61 is screwed out of the locking seat 62, the closing plate 5 is opened and the sliding plate 43 can be withdrawn from the positioning slot. When the rotating pin 61 is screwed into the locking seat 62, the closing plate 5 is closed, and the closing plate 5 abuts against the sliding plate 43, preventing it from sliding.

[0028] A groove 4322 is formed on one side of the sliding plate 43. The shut-off assembly 432 includes a pressure block 4321. The first end of the pressure block 4321 is hinged to the sliding plate 43 and positioned directly below the groove 4322. The second end of the pressure block 4321 is provided with a protrusion that snaps into the groove 4322. When the protrusion snaps into the inner wall of the groove 4322, the pressure block 4321 compresses and blocks the infusion tube. When the liquid storage bottle needs to be replaced, the pressure block 4321 is pressed downward so that the protrusion presses the infusion tube into the groove 4322, preventing liquid from leaking and wasting resources.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
