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

The invention discloses a nucleic acid reaction consumable switch cover mechanism. The mechanism comprises a first architectural layer, a second architectural layer, and a third architectural layer, wherein several guide rods I are vertically arranged below the first architectural layer, the upper ends of the first guide rods I are connected to the first architectural layer, and the lower ends ofthe first guide rods I penetrate the second architectural layer and the third architectural layer; several guide rods II are vertically arranged between the second architectural layer and the third architectural layer, the upper ends of the guide rods II penetrate the second architectural layer, and the lower ends of the guide rods II are connected to the third architectural layer; the guide rodsII are connected to elastic assemblies in a sleeve mode, the first architectural layer is connected to the second architectural layer through a lifting device, and the lifting device is used for driving the second architectural layer to move up and down along the guide rods I; and a consumable cover fixing mechanism is arranged on the second architectural layer, and is used for fixing a consumablecover to the second architectural layer, the third architectural layer is provided with a consumable body fixing mechanism, and the consumable body fixing mechanism is used for limiting movement of aconsumable body. The switch cover mechanism can prevent manual operation from causing sample pollution, and at the same time, the operation efficiency can be improved, and the artificial fatigue strength can be reduced.

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...
