Abstract

The invention discloses a PCR instrument and a heat cover lifting mechanism thereof. The heat cover lifting mechanism comprises a support and a drawing module provided with an EP tube, wherein a heatcover is in sliding fit with the support in the up-down direction; the drawing module is provided with a guiding surface; the guiding surface comprises a horizontal high section, a horizontal low section and a transition section connected between the horizontal high section and the horizontal low section; the heat cover is supported on the guiding surface; by movement of the drawing module in theextending direction of the guiding surface, the supporting positions of the heat cover and the guiding surface can be changed; when the drawing module is in a drawn state, the heat cover supports thehorizontal high section; and when the drawing module is in a pushed-in state, the heat cover supports the horizontal low section and tightly presses a tube cover of the EP tube. According to the provided heat cover lifting mechanism, up-down movement of the heat cover is finished by drawing actions of the drawing module, the heat cover lifting mechanism is operated speedily, a motor is not required, power consumption is avoided, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of PCR, in particular to a PCR instrument and a heating cover lifting mechanism thereof. Background technique [0002] PCR (Polymerase Chain Reaction, polymerase chain reaction) is a molecular biology technology that uses DNA polymerase to amplify specific DNA fragments, and a PCR machine is an instrument that realizes PCR technology. [0003] The PCR instrument mainly includes the lower heating and cooling structure, the upper heating cover and the optical module. The main function of the heating cover is to prevent the liquid from condensing on the top of the EP tube (eppendorf tube, that is, the centrifuge tube) and affect the optical path detection. To realize this function, it is necessary to The heat cap is required to press tightly against the cap of the EP tube. At present, the conventional mechanism for driving the hot cover down is driven by a motor. In addition to the motor, it is necessary to se...
