Problems solved by technology

[0004] The existing nucleic acid reaction consumables include two parts: the main body and the consumable cover. The opening and closing operations of the existing nucleic acid reaction consumables are all done manually, which will increase the risk of sample contamination. At the same time, the efficiency of manual operation is low , and the artificial fatigue intensity is high

Embodiment 1

[0048] A nucleic acid reaction consumables switch cover mechanism, which includes a first frame layer 14, a second frame layer 18 and a third frame layer 19 arranged in sequence from top to bottom; a number of guides are vertically arranged below the first frame layer 14 Rod one 20, the upper end of the guide rod one 20 is connected with the first structure layer 14, and the lower end of the guide rod one 20 runs through the second structure layer 18 and the third structure layer 19, so that the second structure layer 18 and the third structure layer 19 can move up and down along the guide rod one 20; the lower end of the guide rod one 20 is provided with a lower limit block of the guide rod; the lower limit block of the guide rod is located below the third frame layer 19; the second frame layer 18 and the third structure layer 19 are vertically provided with several guide rods 2 27; The upper end of 27 is provided with a guide rod two upper limit block, and the guide rod two ...

Embodiment 2

[0060] This embodiment takes figure 1 The nucleic acid reaction consumable shown is taken as an example to illustrate the opening and closing mechanism of the nucleic acid reaction consumable of the present invention.

[0061] Such as figure 1 Shown is a nucleic acid reaction consumable, which includes a consumable body 1 and a consumable cover 2 . The main body 1 of consumables includes a connecting plate 3 and a plurality of tubes 4 inserted in the connecting plate 3. The tubes 4 have nozzles 5, and the nozzles 5 of all the tubes 4 are on the same plane. The width is greater than the diameter of the nozzle 5 to form a first cornice 6 on the outer wall of the tube body 4 for fixing the tube body 4 when the cover is opened; The tube cover 7 of 5 is connected to the same side of the tube cover plate 8, and the edge of the tube cover 7 is provided with the second eaves 9 as the stress point when the tube cover 7 is pulled up from the tube body 4; the tube cover 7 covers When ...

Abstract

A nucleic acid reaction consumable switch cover mechanism, which includes a first frame layer, a second frame layer and a third frame layer; a number of guide rods are vertically arranged below the first frame layer, and the upper ends of the guide rods are connected to the first frame layer Connected, the lower end of the guide rod 1 runs through the second structure layer and the third structure layer; a number of guide rods 2 are vertically arranged between the second structure layer and the third structure layer; the upper end of the guide rod 2 runs through the second structure layer, and the guide rod 2 The lower end is connected with the third structure layer; the guide rod two is covered with an elastic component; the first structure layer is connected with the second structure layer through a lifting device, and the lifting device is used to drive the second structure layer to move up and down along the guide rod one; The structure layer is provided with a consumable cover fixing mechanism, which is used to fix the consumable cover on the second structure layer; the third structure layer is provided with a consumable body fixing mechanism, which is used to limit the movement of the consumable body. The switch cover mechanism can avoid sample pollution caused by manual operation, and at the same time, can also improve operation efficiency and reduce manual fatigue intensity.

Description

technical field [0001] The invention relates to the field of instrument automation, in particular to a mechanism for opening and closing a nucleic acid reaction consumable. Background technique [0002] Nucleic acid is the carrier of the genetic information of organisms. Whether it is to study nucleic acid sequence and structure, or to explore gene function and expression, it is necessary to separate, purify and detect nucleic acid. [0003] With the advancement of science and technology, the automation of nucleic acid extraction and detection equipment will be an inevitable trend. However, fully automatic nucleic acid detection should not only be limited to the automation of nucleic acid extraction and detection process, but should also include steps such as sample addition, product transfer, and waste treatment, so as to minimize the interaction between operators and samples, reagents, and reaction products. , and contact with waste consumables to reduce the risk of biolo...
