Description

Recombinant antibody extraction device Technical Field The utility model relates to the field of antibody extraction, in particular to a recombinant antibody extraction device. Background Recombinant antibody extraction devices are specialized devices for efficiently and safely extracting, transferring, and storing recombinant antibody samples during antibody production. Such devices typically combine biological sample processing, aseptic handling, and waste management functions to ensure the stability and purity of the antibody sample. When the existing extraction device is used, the antibody sample storage rack lacks a corresponding limiting structure after being transferred into the storage box, so that in the transportation process, if the storage box is knocked over, the sample storage rack can be easily and directly knocked against the inner wall of the storage box, and the reagent bottle is damaged. Accordingly, there is a need to provide a new recombinant antibody extraction device that solves the above-mentioned technical problems. Disclosure of utility model In order to solve the technical problems, the utility model provides a recombinant antibody extraction device, which solves the problem that a reagent bottle is damaged because a sample storage rack is easy to directly collide with the inner wall of a storage box if the storage box is knocked over in the transportation process. The recombinant antibody extraction device provided by the utility model comprises a box body and a reagent storage rack, wherein an L-shaped positioning seat is fixed in the box body, and the reagent storage rack is closely placed on the L-shaped positioning seat; The box body is internally and movably provided with a rotating shaft, a pressing piece is fixed on the rotating shaft, a fixed ring seat is fixed outside the box body, one end of the rotating shaft penetrates through the box body and extends into the fixed ring seat, a scroll spring is arranged inside the fixed ring seat, one end of the scroll spring is fixed on the rotating shaft, and the other end of the scroll spring is fixed on the inner wall of the fixed ring seat. In a preferred embodiment, a fixed block is fixed on the rotating shaft, a first stop block is fixed on one side of the fixed block, a side seat is fixed on one side of the box body, a sliding groove is formed in one side of the side seat, and a second stop block is slidably arranged in the sliding groove. In a preferred embodiment, a push rod is fixed to one side of the fixed block. In a preferred embodiment, the reagent storage rack is provided with a plurality of reagent bottle placing grooves, and limiting silica gel pads are fixed at the groove walls of the reagent bottle placing grooves. In a preferred embodiment, a handle is fixed to the top of the case. The utility model has the beneficial effects that: When the reagent storage rack is placed in the box body for transferring, a worker only needs to cling the reagent storage rack to the L-shaped positioning seat, and the second stop block is stirred to cancel the limit of the rotating shaft, at the moment, the rotating shaft drives the pressing piece to rotate downwards under the action of the scroll spring to fix the reagent storage rack, so that the reagent storage rack is prevented from moving when the box body is overturned, and an antibody reagent bottle is prevented from being damaged; When the reagent storage rack needs to be taken out, only the push rod needs to be stirred, after the first check block moves to the upper side of the second check block, the second check block moves to the rightmost side, the push rod is loosened at the moment, the pressing piece cannot move under the action of the two check blocks, and the reagent storage rack can be taken out at the moment, so that the operation is simple and convenient.
