However, traditional reagent cards are prone to shaking after being inserted into the fluorescence analyzer, and if not handled properly, the reagent card may fall off the analyzer, causing contamination and affecting detection efficiency and quality. Utility Model Content
[0003] To address the aforementioned technical problems, the main objective of this invention is to provide a reagent card insertion structure and a fluorescence analyzer, aiming to solve the problem that traditional fluorescence analyzers have a risk of reagent cards falling off during testing, which seriously affects testing efficiency and quality.
[0004] To achieve the above objectives, this utility model proposes a reagent card insertion structure, including an insertion base, an insertion groove formed on the insertion base, and a guide and limiting structure disposed at the bottom of the insertion groove. One side of the insertion groove is open to allow a reagent card to be inserted into the insertion groove. At least a portion of the guide and limiting structure can extend into the insertion groove and guide the reagent card toward its direction of movement. When the reagent card is inserted into the insertion groove, the guide and limiting structure abuts against at least one side of the reagent card to restrict its movement.

[0006] Optionally, the bottom of the insertion slot is provided with a limiting hole, and the guiding limiting structure includes a guiding spring piece. The guiding spring piece is connected to the bottom of the insertion base and covers the bottom of the limiting hole. The portion of the guiding spring piece covering the limiting hole is arc-shaped and protrudes from the bottom of the insertion slot.
[0007] Optionally, the guide spring has a first connecting segment and a second connecting segment arranged opposite to each other, and a guide segment connecting the first connecting segment and the second connecting segment. The guide surface is formed on the guide segment. The first connecting segment is connected to the insertion base and is located on one side of the limiting hole. The second connecting segment is suspended and located on the other side of the limiting hole. The guide segment is bent along the insertion or removal direction of the reagent card.
[0008] Optionally, the bottom of the plug-in base is provided with a downward-facing receiving groove, the first connecting segment is connected to the edge of the groove opening of the receiving groove, the second connecting segment is located inside the receiving groove, and when the guide segment undergoes elastic deformation and displacement under the abutment of the reagent card, the second connecting segment does not protrude from the groove opening of the receiving groove.
[0009] Optionally, two sets of the guiding and limiting structures are provided, and the two sets of guiding and limiting structures are arranged at intervals along the insertion or removal direction of the reagent card.
[0010] Optionally, the shape of the insertion slot is adapted to match the shape of the reagent card, the insertion slot is elongated and has a long side and a short side, and one of the short sides of the insertion slot is open.

[0014] The technical solution provided by this utility model has the following beneficial effects:
[0015] The reagent card insertion structure provided by this utility model includes an insertion base, an insertion slot, and a guide and limiting structure. The insertion slot is formed on the insertion base, which can be installed and fixed on a fluorescence analyzer. One side of the insertion slot is open, allowing the reagent card to extend into the slot from the open side. The insertion slot limits the reagent card, ensuring that the fluorescence analyzer can detect the detection area on the reagent card when it is properly inserted. Furthermore, the guide and limiting structure guides the reagent card during insertion or removal, allowing the reagent card to be inserted more easily and safely. The reagent card insertion is smoother and feels better. On the other hand, the guide and limiting structure can abut against at least one side of the reagent card, making it less likely to shake in the insertion slot under the combined limiting effect of the guide and limiting structure and the insertion slot or other components of the fluorescence analyzer. Therefore, the detection alignment of the reagent card is more accurate and the detection results are more reliable. Moreover, under the abutting effect of the guide and limiting structure, the reagent card is not easy to fall out of the insertion slot. After the reagent card is inserted, it is more convenient for the operator to perform the detection operation, which helps to improve the detection efficiency and detection quality.

[0030] This utility model provides a reagent card insertion structure 100, which is suitable for a fluorescence analyzer 1000. The reagent card insertion structure 100 is used to insert a detection reagent card 200 into it, so that when the reagent card 200 is inserted in place, the fluorescence analyzer 1000 can better detect the sample to be tested on the reagent card 200.
[0031] Specifically, please refer to Figures 1 to 2 In this embodiment, the reagent card insertion structure 100 includes an insertion base 1, an insertion groove 13 formed on the insertion base 1, and a guide limiting structure 2 disposed at the bottom of the insertion groove 13. One side of the insertion groove 13 is open to allow the reagent card 200 to be inserted into the insertion groove 13. At least a portion of the guide limiting structure 2 can extend into the insertion groove 13 and guide the reagent card 200 toward its moving direction. When the reagent card 200 is inserted into the insertion groove 13, the guide limiting structure 2 abuts against at least one side of the reagent card 200 to restrict its movement.
[0032] In this embodiment, the insertion base 1 can be installed and fixed on the fluorescence analyzer 1000, and one side of the insertion slot 13 is open, allowing the reagent card 200 to extend into the insertion slot 13 from the open side. The insertion slot 13 limits the reagent card 200 to ensure that the fluorescence analyzer 1000 can detect the detection area on the reagent card 200 when it is inserted correctly. Furthermore, the guide limiting structure 2 guides the reagent card 200 during insertion or removal, making the insertion smoother and more comfortable. The guiding and limiting structure 2 can abut against at least one side of the reagent card 200, making it less likely for the reagent card 200 to shake within the insertion slot 13 under the combined limiting action of the guiding and limiting structure 2 and the insertion slot 13 or other components of the fluorescence analyzer 1000. Therefore, the detection alignment of the reagent card 200 is more accurate and the detection results are more reliable. Moreover, under the abutting action of the guiding and limiting structure 2, the reagent card 200 is also less likely to fall out of the insertion slot 13. After the reagent card 200 is inserted into place, it is more convenient for operators to perform detection operations, which helps to improve detection efficiency and detection quality.
[0033] The entire reagent insertion structure 100 can be fixedly installed within the housing 300 of the fluorescence analyzer 1000. When the fluorescence analyzer 1000 is in normal use, the insertion slot 13 is positioned with its opening facing upwards, and the side of the insertion slot 13 opposite to its opening is the bottom of the insertion slot 13. The shape of the insertion slot 13 is adapted to match the shape of the reagent card 200. The insertion slot 13 is elongated, having a long side and a short side. One of the short sides of the insertion slot 13 is open. The direction of the long side is the length direction of the insertion slot 13, and the direction of the short side is the width direction of the insertion slot 13. The direction opposite to the opening and bottom of the insertion slot 13 is its height direction, thus the insertion slot 13 is open at one end in its width direction. A through hole may be provided on the housing 300 of the fluorescence analyzer 1000, and the open side of the insertion slot 13 may be opposite to the through hole, so that the reagent card 200 can be inserted into the insertion slot 13 from the through hole.
[0034] Furthermore, the open side of the insertion slot 13 is provided with chamfers extending outward from both sides. When the reagent card 200 is inserted into the insertion slot 13, the two chamfers can guide the insertion of the reagent card 200 more smoothly.
[0035] Preferably, such as Figure 2 As shown, a clearance groove 14 is provided on the other short side of the insertion groove 13. That is, on one side of the groove width of the insertion groove 13, the clearance groove 14 is recessed on the groove wall of the insertion groove 13, so that when the reagent card 200 is inserted into the groove 13, a clearance gap is formed between the reagent card 200 and the insertion groove 13. On the one hand, this makes it easier to process the insertion groove 13, and on the other hand, it allows the airflow to be better discharged from the clearance groove 14 when the reagent card 200 is inserted into the insertion groove 13, so as not to accumulate at the end of the insertion groove 13 and create insertion resistance to the reagent card 200.
[0036] The guiding and limiting structure 2 is mainly used to guide the insertion of the reagent card 200 and simultaneously limit its position. Preferably, it is combined with... Figure 2 and Figure 3 As shown, the guiding and limiting structure 2 has an arc-shaped guiding surface, and the guiding surface is elastically deformable. Through the guiding effect of the arc-shaped guiding surface, the reagent card 200 comes into contact with the arc-shaped surface to form a surface-to-line contact. The contact area is smaller, resulting in less frictional resistance, making it easier and less strenuous to insert the reagent card 200.
[0037] Specifically, a limiting hole 11 is provided at the bottom of the insertion slot 13. The guiding limiting structure 2 includes a guiding spring 21. The guiding spring 21 is connected to the bottom of the insertion base 1 and covers the bottom of the limiting hole 11. The portion of the guiding spring 21 covering the limiting hole 11 is arc-shaped and protrudes from the bottom of the insertion slot 13. Thus, when the reagent card 200 is inserted into the insertion slot 13, the reagent card 200 can be raised under the abutting action of the guiding spring 21 to be spaced from the bottom of the insertion slot 13, so that the insertion is smooth and the reagent card 200 is not easily moved under the abutting action of the guiding limiting structure 2.
[0038] Preferably, combined with Figure 4 and Figure 5 As shown, the guide spring 21 has a first connecting section 211 and a second connecting section 212 arranged opposite to each other, and a guide section 213 connecting the first connecting section 211 and the second connecting section 212. The guide surface is formed on the guide section 213. The first connecting section 211 is connected to the insertion base 1 and is located on one side of the limiting hole 11. The second connecting section 212 is suspended and located on the other side of the limiting hole 11. The guide section 213 is bent along the insertion or removal direction of the reagent card 200. Specifically, the first connecting section 211 is connected and fixed to the insertion base 1 by a connector, such as a screw or bolt. Along the insertion direction of the reagent card 200, the second connecting segment 212 and the first connecting segment 211 are arranged opposite to each other, and the second connecting segment 212 is located behind the first connecting segment 211. When the reagent card 200 is inserted into the insertion slot 13, the reagent card 200 presses against the guide segment 213, causing elastic deformation at the connection between the guide segment 213 and / or the first connecting segment 211, thereby causing the second connecting segment 212 to move downward. At the same time, under the action of the rebound force of the guide spring 21, the guide segment 213 can press against the reagent card 200 to limit the reagent card 200.
[0039] Moreover, such as Figure 5 As shown, a downward-facing receiving groove 12 is provided at the bottom of the plug-in base 1. The first connecting section 211 is connected to the edge of the groove of the receiving groove 12. The second connecting section 212 is located inside the receiving groove 12. When the guide section 213 undergoes elastic deformation and displacement under the abutment of the reagent card 200, the second connecting section 212 does not protrude from the groove of the receiving groove 12. This ensures that the guide spring 21 has sufficient deformation while preventing the guide spring 21 from extending out of the receiving groove 12 and interfering with other components.
[0040] The limiting hole 11 is provided to penetrate the bottom of the receiving groove 12, and the bottom of the limiting hole 11 is provided with a guide surface. In the direction from top to bottom, the guide surface is gradually widened outward, so that the guide section 213 has enough room to move.
[0041] Preferably, two sets of the guide limiting structure 2 are provided, and the two sets of the guide limiting structure 2 are arranged at intervals along the insertion or insertion direction of the reagent card 200, so that they can better abut against multiple points of the reagent card 200 and provide better support for the reagent card 200.
[0042] This utility model also provides a fluorescence analyzer 1000, combined with... Figure 6 and Figure 7 As shown, the fluorescence analyzer 1000 includes the aforementioned reagent card insertion structure 100 and a housing 300. A through hole is provided on one side of the housing 300, through which the reagent card 200 can extend into the housing 300 and be inserted into the insertion slot 13 of the reagent card insertion structure 100. The reagent card 200 is guided and limited by the guide and limiting structure 2, so that the reagent card 200 is not easy to shake or fall off when the fluorescence analyzer 1000 is in use, making it more convenient to use and effectively improving detection efficiency and detection quality.
[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
