Description

Technical Field

[0001] This utility model relates to the field of antibody extraction, and in particular to a recombinant antibody extraction device. Background Technology

[0002] Recombinant antibody extraction devices are specialized equipment used for the efficient and safe extraction, transfer, and storage of recombinant antibody samples during antibody production. These devices typically combine functions such as biosample handling, aseptic operation, and waste management to ensure the stability and purity of antibody samples.

[0003] When using existing extraction devices, the antibody sample storage rack lacks a corresponding limiting structure after being transferred into the storage box. Therefore, if the storage box is overturned during transportation, the sample storage rack can easily hit the inner wall of the storage box, resulting in damage to the reagent bottle.

[0004] Therefore, it is necessary to provide a new recombinant antibody extraction device to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a recombinant antibody extraction device, which solves the problem that if the storage box is overturned during transportation, the sample storage rack can easily collide directly with the inner wall of the storage box, thereby damaging the reagent bottles.

[0006] The recombinant antibody extraction device provided by this utility model includes a box and a reagent storage rack. An L-shaped positioning seat is fixed inside the box, and the reagent storage rack is placed close to the L-shaped positioning seat.

[0007] A rotating shaft is movably arranged inside the box, and a clamping plate is fixed on the rotating shaft. A fixing ring seat is fixed outside the box. One end of the rotating shaft passes through the box and extends into the fixing ring seat. A spiral spring is arranged inside the fixing ring seat. One end of the spiral spring is fixed to the rotating shaft, and the other end of the spiral spring is fixed to the inner wall of the fixing ring seat.

[0008] In a preferred embodiment, a fixing block is fixed on the rotating shaft, a first stop block is fixed on one side of the fixing block, a side seat is fixed on one side of the box body, a sliding groove is provided on one side of the side seat, and a second stop block is slidably disposed inside the sliding groove.

[0009] In a preferred embodiment, a push rod is fixed to one side of the fixing block.

[0010] In a preferred embodiment, the reagent storage rack has several reagent bottle placement slots, and a limiting silicone pad is fixed to the wall of each reagent bottle placement slot.

[0011] In a preferred embodiment, a handle is fixed to the top of the box.

[0012] The beneficial effects of this utility model are:

[0013] When transferring this reagent storage rack inside the box, the staff only needs to place the reagent storage rack close to the L-shaped positioning seat, and then move the second stop to release the limit on the rotating shaft. At this time, under the action of the spiral spring, the rotating shaft drives the clamping plate to rotate downward to complete the fixation of the reagent storage rack, preventing the reagent storage rack from moving when the box is overturned and preventing damage to the antibody reagent bottles.

[0014] When you need to remove the reagent storage rack, simply move the push rod. After the first stop moves above the second stop, move the second stop to the far right. Then release the push rod. Under the action of the two stops, the clamping plate will not move, and the reagent storage rack can be removed. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A three-dimensional view of the main structure of the recombinant antibody extraction device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of A shown; Figure 3 A plan view of the main structure of the recombinant antibody extraction device provided by this utility model.

[0021] In the specific implementation process, such as Figures 1-3As shown, the device includes a box body 1 and a reagent storage rack 2. A handle 16 is fixed to the top of the box body 1 to facilitate the transfer of the box body 1 by the staff. An L-shaped positioning seat 3 is fixed inside the box body 1. The reagent storage rack 2 is placed close to the L-shaped positioning seat 3. A rotating shaft 4 is movably arranged inside the box body 1. A clamping plate 5 is fixed on the rotating shaft 4. The surface of the clamping plate 5 is treated with friction. Under the action of friction between the clamping plate 5 and the reagent storage rack 2, the reagent storage rack 2 can be prevented from moving when the box body 1 is transferred.

[0022] A fixing ring seat 6 is fixed to the outside of the box body 1. One end of the rotating shaft 4 passes through the box body 1 and extends into the fixing ring seat 6. A spiral spring 7 is installed inside the fixing ring seat 6. One end of the spiral spring 7 is fixed to the rotating shaft 4, and the other end of the spiral spring 7 is fixed to the inner wall of the fixing ring seat 6. When the reagent storage rack 2 is placed inside the box body 1 for transfer, the staff only needs to place the reagent storage rack 2 close to the L-shaped positioning seat 3 and move the second stop 12 to release the limit on the rotating shaft 4. At this time, under the action of the spiral spring 7, the rotating shaft 4 drives the clamping plate 5 to rotate downward to complete the fixation of the reagent storage rack 2, so as to prevent the reagent storage rack 2 from moving when the box body 1 is overturned, thereby preventing the antibody reagent bottle from being damaged. The reagent storage rack 2 has several reagent bottle placement slots 14. A limiting silicone pad 15 is fixed to the wall of the reagent bottle placement slot 14. When the reagent bottle is placed into the reagent bottle placement slot 14, the friction between the limiting silicone pad 15 and the reagent bottle will prevent the reagent bottle from falling when the box body 1 is overturned.

[0023] A fixing block 8 is fixed on the rotating shaft 4. A first stop block 9 is fixed on one side of the fixing block 8. A side seat 10 is fixed on one side of the box body 1. A sliding groove 11 is opened on one side of the side seat 10. A second stop block 12 is slidably arranged inside the sliding groove 11. A push rod 13 is fixed on one side of the fixing block 8, which makes it convenient for the staff to rotate the rotating shaft 4. When the reagent storage rack 2 needs to be taken out, just push the push rod 13. After the first stop block 9 moves above the second stop block 12, move the second stop block 12 to the rightmost side. At this time, release the push rod 13. Under the action of the two stops, the clamping plate 5 will not move. At this time, the reagent storage rack 2 can be taken out.

[0024] The working principle of this utility model is as follows: When the reagent storage rack 2 is placed inside the box 1 for transfer, the staff only needs to place the reagent storage rack 2 close to the L-shaped positioning seat 3, and then move the second stop 12 to remove the limit on the rotating shaft 4. At this time, under the action of the spiral spring 7, the rotating shaft 4 drives the clamping plate 5 to rotate downward to complete the fixation of the reagent storage rack 2, so as to prevent the reagent storage rack 2 from moving when the box 1 is overturned.

[0025] When it is necessary to remove the reagent storage rack 2, simply move the push rod 13. After the first stop 9 moves above the second stop 12, move the second stop 12 to the far right. At this time, release the push rod 13. Under the action of the two stops, the clamping plate 5 will not move. Then, the reagent storage rack 2 can be removed.
