[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0021] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0022] In order to prevent the reagent kit or cleaning box from being inserted into the instrument again when the reagent kit follows the reagent kit slot to the puncture position during the sequencing process, the reagent kit slot module is designed to be foolproof in structure. When the user inserts the reagent kit or cleaning box again during the sequencing process, the hinge will be blocked. The hinge will swing with the up and down movement of the reagent kit slot.
[0023] like Figure 1-4 As shown:
[0024] On the one hand, the utility model provides a fool-proof structure for inserting a reagent kit into a gene sequencer, comprising: a fixed part 11 and a movable part 12, wherein the fixed part 11 is fixedly connected to the bottom of the reagent kit slot 2 of the gene sequencer 4; one end of the movable part 12 is rotatably connected to the fixed part 11, and the other end extends toward the reagent kit inlet direction of the gene sequencer 4 and contacts the bottom of the gene sequencer 4 to block the space below the reagent kit slot.
[0025] Specifically, a foolproof structure 1 is provided at the bottom of the reagent box slot 2, wherein one end of the movable portion 12 is rotatably connected to the fixed portion 11, and the other end extends toward the reagent box entrance of the gene sequencer 4 and contacts the bottom of the gene sequencer 4. Since the movable portion 12 is rotatable relative to the fixed portion 11, when the fixed portion 11 moves in the up and down directions along with the reagent box slot, one end of the movable portion 12 is rotatably connected to the fixed portion 11, and the other end of the movable portion 12 extends toward the reagent box entrance. Under the action of gravity, the movable portion 12 is located between the bottom of the reagent box slot and the bottom of the gene sequencer 4 in an inclined state toward the entrance, as shown in FIG. Figure 1 As shown, when the reagent reagent slot 2 rises to the puncture position, i.e., the uppermost position, the movable portion 12 is located in the lower space of the reagent reagent slot, i.e., between the bottom of the reagent reagent slot and the bottom of the gene sequencer 4, and blocks the lower space of the reagent reagent slot, so that the mis-installed reagent reagent 3' cannot be inserted into the gene sequencer 4 again.
[0026] In some embodiments, a rotating shaft 15 is further included, and the movable part 12 is rotatably connected to the fixed part 11 via the rotating shaft 15 .
[0027] Specifically, the fixed portion 11 and the movable portion 12 are connected by the rotating shaft 15 , so that the movable portion 12 can rotate relative to the fixed portion 11 .
[0028] In some embodiments, one end of the fixed part 11 has a fixed part reel 13, and the end of the movable part 12 connected to the fixed part 11 is provided with a movable part reel 14, the fixed part reel 13 and the movable part reel 14 are coaxially arranged, and the rotating shaft 15 is passed through the fixed part reel 13 and the movable part reel 14.
[0029] Specifically, the reel is rotatably connected to the rotating shaft 15, which has a simple structure and is easy to install.
[0030] In some embodiments, the number of the fixed portion reels 13 is two, and the movable portion reel 14 is located between the two fixed portion reels 13 .
[0031] Specifically, the movable part reel 14 is placed between the two fixed part reels 13, and the connection is stable and reliable.
[0032] In some embodiments, the length of the movable portion 12 is greater than the distance between the bottom of the reagent cartridge slot 2 and the inner bottom surface of the housing of the gene sequencer when the reagent cartridge slot 2 is located at the uppermost position.
[0033] Specifically, the length of the movable part 12 is set to be greater than the distance between the bottom of the reagent reagent slot 2 and the inner bottom surface of the gene sequencer shell when the reagent reagent slot 2 is in the uppermost position, so that the movable part 12 always extends toward the entrance of the reagent reagent slot 3 to prevent the reagent reagent from being accidentally inserted when the reagent reagent slot 2 is in the uppermost position.
[0034] In some embodiments, the fixed portion 11 and the movable portion 12 are respectively sheet-shaped structures.
[0035] In some embodiments, the fixing portion 11 is fixedly connected to the bottom of the reagent chamber slot 2 by welding.
[0036] In some embodiments, a torsion spring is provided between the fixed part 11 and the movable part 12 so that the movable part 12 is elastically pressed against the bottom of the gene sequencer 4. In this way, the movable part can be prevented from shaking freely, noise and vibration can be reduced, and the stability of the instrument during operation can be increased.
[0037] On the other hand, the utility model also provides a gene sequencer 4, including a reagent kit for a gene sequencer 4 as described above and an anti-fool structure 1 for insertion.
[0038] An anti-fool-proof structure 1 is provided at the bottom of the reagent reagent slot 2 of the gene sequencer 4. When the reagent reagent 3 follows the reagent reagent slot 2 to rise to the puncture position, the movable part 12 of the hinge-type anti-fool-proof structure 1 swings up and down with the reagent reagent slot, preventing the reagent reagent or cleaning box from being inserted into the instrument again at this time, thereby ensuring the normal operation of the gene sequencer 4.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
