Description

Technical Field

[0002] Nucleic acid extraction is an important experimental method in the field of medical testing. In nucleic acid extraction experiments, certain steps require raising (e.g., raising to 120°C) or lowering (e.g., lowering to 5°C) the temperature of the reactants loaded in the deep well plate in order to meet the requirements of biochemical reactions.

[0003] Currently, in similar experimental equipment, the temperature raising or lowering steps are usually transferred to an external temperature control device. This method of raising or lowering the temperature requires moving the deep well plate containing nucleic acid back and forth, which not only reduces experimental efficiency but also affects experimental accuracy.

[0004] Nucleic acid extraction requires specialized extraction equipment. The technical problem that needs to be solved is how to heat or cool the reactants inside the deep well plate without removing the plate from the extraction equipment. Utility Model Content

Figures 1-4 It mainly includes components such as a linear drive mechanism 1, a height lifting mechanism 2, a carrier plate 3, a temperature lifting module 4, and a contour jig 5. The linear drive mechanism 1 is connected to the height lifting mechanism 2 and drives the height lifting mechanism 2 to perform lifting actions. In this embodiment, the linear drive mechanism 1 uses a servo electric cylinder. The carrier plate 3 is connected to the upper end of the height lifting mechanism 2, and the height lifting mechanism 2 drives the carrier plate 3 to move up and down. The temperature lifting module 4 is connected to the upper end of the carrier plate 3, and the carrier plate 3 supports the temperature lifting module 4. The temperature lifting module 4 is existing technology; for example, a PCR heating and cooling module can be used, which has both heating and cooling functions.

The first limiting frame 23 and the second limiting frame 24 are arranged vertically opposite each other. The first movable arm 21 is connected to the second movable arm 22 by a pin in an "X" shape.

The linear drive mechanism 1 is connected to the lower end of the first movable arm 21; the carrier plate 3 is fixed to the upper end of the top plate 25.

[0024] See Figure 1 and Figure 3 The working process of the height lifting mechanism 2 is as follows: During the upward movement, the movable end of the linear drive mechanism 1 extends outward, pushing the lower end of the first movable arm 21 towards the lower end of the second movable arm 22. The upper ends of the first movable arm 21 and the second movable arm 22 move closer together and move upward synchronously. During the upward movement of the upper ends of the first movable arm 21 and the second movable arm 22, the carrier plate 3 moves upward synchronously. During the downward movement, the movable end of the linear drive mechanism 1 retracts inward, driving the lower end of the first movable arm 21 away from the lower end of the second movable arm 22. The upper ends of the first movable arm 21 and the second movable arm 22 separate and move downward synchronously. During the downward movement of the upper ends of the first movable arm 21 and the second movable arm 22, the carrier plate 3 moves downward synchronously.
