Description

Technical Field

[0001] The utility model belongs to the technical field of flip cover devices, and in particular relates to a flip cover device for sample detection equipment and the sample detection equipment. Background Art

[0002] Polymerase chain reaction (PCR) is a molecular biology technique used to amplify specific DNA fragments. It can be regarded as a special DNA replication outside the body. The biggest feature of PCR is that it can greatly increase the amount of DNA. Polymerase chain reaction is a method of enzymatically synthesizing specific DNA fragments in vitro. It consists of a cycle of high-temperature denaturation, low-temperature annealing (renaturation) and temperature-appropriate extension. The cycle allows the target DNA to be rapidly amplified. It has the characteristics of strong specificity, high sensitivity, simple operation and time saving.

[0003] At present, PCR instruments are widely used in the biological and medical fields, mainly for nucleic acid detection. PCR instruments are usually equipped with a pressure cover for covering the sample tube. The pressure cover can prevent heat from escaping, thereby preventing the water vapor in the sample tube from condensing on the tube cover, thereby improving the accuracy of nucleic acid detection. In the prior art, the pressure cover is turned too hard during the opening and closing process, and it is very easy to collide with the outer shell of the PCR instrument when it is turned to the extreme angle, resulting in damage to the pressure cover or the outer shell, and generating a large noise that affects the user experience.
