Description

Technical Field

[0001] The utility model relates to the technical field of antibody sample addition, and particularly relates to an antibody reagent batch sample addition device. Background Art

[0002] In the process of antibody tests in biopharmaceuticals, according to test requirements, sample addition of multiple specimens is required. Therefore, an antibody reagent batch sample addition device is needed.

[0003] For example, a Chinese patent (Publication No.: CN218107710U) discloses an antibody reagent batch sample addition device, which includes: a sample addition box body; support frames arranged at the lower parts of opposite side walls of the sample addition box body, respectively used for placing a dropper box and a liquid collection box; a sample addition container arranged on the sample addition box body; a liquid inlet main pipe communicating with the sample addition container, which is provided with a liquid inlet solenoid valve; a liquid outlet main pipe communicating with the sample addition container, which is provided with a liquid outlet solenoid valve and extends into the sample addition box body; and a liquid distribution branch pipe fixed in the sample addition box body, which communicates with the liquid outlet main pipe and is located above the dropper box. This utility model uses the liquid collection box as a prevention to collect the reagent that overflows due to excessive sample addition caused by operation errors and can be poured out in time, thus conveniently solving this problem.

[0004] For the above-mentioned antibody reagent batch sample addition device, during use, the liquid collection box can be first pushed into the sample addition box body, and then the dropper box can be inserted or removed. The liquid collection box is located below the dropper box. However, pushing the liquid collection box into the sample addition box body is not convenient for limiting the positions of the liquid collection box and the dropper box. As a result, during the use of the liquid collection box and the dropper box, the positions of the liquid collection box and the dropper box cannot be guaranteed, resulting in the liquid collection box and the dropper box not being completely located below the liquid distribution branch pipe, and a large amount of reagent cannot accurately enter the inside of the dropper box, affecting the effect of batch sample addition and causing waste of the reagent. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an antibody reagent batch sample addition device to solve the above problems existing in the prior art.

[0006] The technical problem to be solved by the utility model is to provide an antibody reagent batch sample addition device.

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] An antibody reagent batch sample addition device includes a box body. Two fixed frames are arranged at the bottom of the inner cavity of the box body. A collection box and a dropper plate are arranged on the fixed frames. An installation mechanism is arranged inside the fixed frames.

The two ends of the lead screw have reverse threads, and both ends of the lead screw are threadedly connected with moving blocks. An articulated rod is hinged on the moving block. One side of the two articulated rods away from the moving block is hinged with a moving plate. A plurality of clamping rods are provided on the opposite sides of the two moving plates. A plurality of first clamping grooves are opened on the opposite sides of the two installation blocks. The lower clamping rods are slidably connected inside the first clamping grooves. The installation mechanism further includes a plurality of second clamping grooves opened on the left and right sides of the dropper plate. The upper clamping rods are slidably connected inside the second clamping grooves.

[0010] The beneficial effects of the present utility model are as follows: By sliding the installation block into the limiting groove and rotating the lead screw, the lead screw drives the two moving blocks to move relatively at the same time. When the moving blocks move, they will drive the articulated rods to rotate, and drive the moving plate to move through the articulated rods. The moving plate drives a plurality of clamping rods to move together, so that the clamping rods are respectively clamped into the first clamping grooves and the second clamping grooves to limit the collection box and the dropper plate, prevent deviation of the dropper plate during use, and improve the effect of sample addition.

[0011] On the basis of the above technical solutions, the present utility model can be further improved as follows.

[0012] Further, a rotating handle is fixed to one end of the lead screw located outside the fixed frame.

[0013] Further, two T-shaped sliders are fixed to the lower surface of the dropper plate, and T-shaped chutes are opened on the upper surface of the fixed frame. The T-shaped sliders are slidably connected inside the T-shaped chutes.

Two fixed frames 2 are provided at the bottom of the inner cavity of the box body 1. A collection box 4 and a dropper plate 5 are provided on the fixed frames 2. An installation mechanism 3 is provided inside the fixed frames 2. The collection box 4 and the dropper plate 5 are fixed by the installation mechanism 3, improving the stability of the collection box 4 and the dropper plate 5.

[0023] The installation mechanism 3 includes a cavity 301 opened inside the fixed frame 2 and a limiting groove 308 opened on the opposite sides of the two fixed frames 2. An installation block 307 fixed to the collection box 4 is slidably connected inside the limiting groove 308. The back of the inner cavity of the cavity 301 is rotatably connected by a bearing to a lead screw 302 passing through the round hole of the fixed frame 2. The two ends of the lead screw 302 are reverse threads. Both ends of the lead screw 302 are threadedly connected with moving blocks 303. By rotating the lead screw 302, the two moving blocks 303 are driven to move relatively or away from each other at the same time. Hinge rods 304 are hinged on the moving blocks 303. One side of the two hinge rods 304 away from the moving blocks 303 is hinged with a moving plate 305. A plurality of clamping rods 306 are provided on the opposite sides of the two moving plates 305. A plurality of first clamping grooves 309 are opened on the opposite sides of the two installation blocks 307. The lower clamping rods 306 are slidably connected inside the first clamping grooves 309.

When the moving blocks 303 move, they will drive the hinge rods 304 to rotate, and drive the moving plate 305 to move through the hinge rods 304. The moving plate 305 drives a plurality of clamping rods 306 to move together, so that the clamping rods 306 are respectively clamped into the interiors of the first clamping slot 309 and the second clamping slot 310, to limit the collection box 4 and the dropper plate 5, prevent deviation of the dropper plate 5 during use, and improve the effect of sample addition.
