The device corresponding to this technical solution includes a colloidal gold / dry fluorescence reagent card, an optical detection module and a reagent card moving component. The reagent card is moved to the corresponding detection position of the optical detection module by the moving component for scanning detection.

[0003] The reagent card detection and scanning structure in the prior art is usually a single detection channel or a design with multiple identical detection channels in parallel. For a multi-channel reagent card detection and scanning device, multiple reagent cards often cannot be placed in place accurately, making it difficult to accurately position, which brings inconvenience to detection, affects the detection results, and even leads to detection failure. In addition, the multi-channel reagent card detection and scanning device also has the problem of cumbersome assembly.

[0004] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve. Content of the Utility Model

[0005] Aiming at the deficiencies in the background art, the utility model provides a multi-channel reagent card detection structure with simple structure assembly, high integral strength and no deformation, which solves the problem of difficult accurate positioning and detection of multiple reagent cards.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A multi-channel reagent card detection structure includes an integral card slot, which is buckled and fixed above a thermostatic plate. There are multiple card insertion channels arranged at equal intervals between the integral card slot and the thermostatic plate;

[0008] A circuit board is installed at the side end of the integral card slot along the length direction. A plurality of photoelectric contact switches are arranged on the side of the circuit board close to the integral card slot, and the photoelectric contact switches are respectively located at the ends of the card insertion channels;

[0009] A metal elastic sheet is arranged on one side part of the card insertion channel along the length direction, and the metal elastic sheet presses and fixes the reagent card horizontally.

[0010] Further, the integral card slot adopts an integral injection molding structure.

[0011] Further, the metal elastic sheet is installed in a elastic sheet installation groove, the elastic sheet installation groove is communicated with the card insertion channel, and a trapezoidal limiting part for clamping the metal elastic sheet is arranged inside the elastic sheet installation groove.

[0012] Furthermore, the metal shrapnel is integrally in a W-shaped structure. The middle part of the metal shrapnel is clamped and pressed through a trapezoidal limiting part, and arc-shaped structures for pressing the reagent card are respectively arranged at both ends of the metal shrapnel.

[0013] Furthermore, both ends of the integrated card slot in the length direction are respectively connected to the thermostatic plate by screws.

[0014] Furthermore, detection holes corresponding to the card insertion channels one by one are respectively arranged above the card insertion channels, and the detection holes are used for the penetration of the detection light path.

[0015] Furthermore, the circuit board is connected to the integrated card slot by screws.

[0016] Furthermore, the photoelectric contact switches are arranged in one-to-one correspondence with the card insertion channels.

[0017] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0018] The metal shrapnel on the side of the reagent card presses the reagent card against the opposite side under the action of elastic force, presses and fixes it horizontally, and detects whether the reagent card is installed in place through the photoelectric contact switch. The photoelectric contact switch and the side metal shrapnel limit the fixed position distances of the reagent card in the front, back, left and right directions, ensuring that multiple reagent cards can be accurately detected simultaneously;
