Description

Technical Field

[0001] The utility model relates to a fluorescence immunoassay chromatograph detector, specifically to a door lifting and switching structure for a fluorescence immunoassay quantitative analyzer. Background Art

[0002] The fluorescence immunoassay chromatography technology is a new type of quantitative detection technology developed by combining immuno-fluorescence technology and traditional immunoassay chromatography technology. In addition to retaining the advantages of simple operation, rapid detection, and strong portability of colloidal gold immunoassay chromatography technology, this technology also realizes precise quantification of detection results through fluorescence tracer enhancement technology. As a rapid detection method, fluorescence immunoassay chromatography has been widely used in the fields of food detection, medical testing, etc.

[0003] There is no shielding at the card insertion place of the existing fluorescence immunoassay chromatograph detector, and the card insertion opening is in an exposed state, which affects the internal environment of the incubation tray and is not conducive to detection.

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

[0005] Aiming at the deficiencies in the background art, the utility model provides a door lifting and switching structure, which can open or close the card insertion opening according to the detection needs. The opening and closing process is stable, the structural principle is simple, and it saves space.

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

[0007] A door lifting and switching structure includes a door, which is located above the bottom shell and inside the front shell. The door cooperates with the front and rear access baffles and springs to realize lifting. The door opens and closes the card insertion opening on the front shell during the lifting process;

[0008] A plurality of PU rubber rollers are installed at the end of the door away from the front shell, and the PU rubber rollers are in rolling connection with the front and rear access baffles;

[0009] Two symmetrically arranged guiding bearings are fixed inside the door, and a guiding column arranged in the vertical direction penetrates through the guiding bearings. The bottom end of the guiding column is fixedly connected to the bottom shell.

[0010] Furthermore, two symmetrically arranged springs are installed between the door and the bottom shell, and the two springs are located outside the two guiding bearings.

[0011] Furthermore, the front shell and the bottom shell are vertically arranged, and a plurality of card insertion openings are transversely opened on the front shell, and the plurality of card insertion openings are equidistantly arranged.

[0012] Further, a plurality of PU rubber rollers are arranged at equal intervals, and the PU rubber rollers are rotatably connected to the bin door through pin shafts.

[0013] Further, one side of the front and rear access flaps close to the PU rubber rollers is inclined.

[0014] Further, a limiting strip is provided on the inner wall of the front shell. The limiting strip is arranged horizontally and limits the upper high point of the bin door.

[0015] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0016] When the front and rear access flaps move forward to contact the PU rubber rollers, the bin door and the guide bearing move downward along the guide column, and the bin door descends to open the inlet; when the front and rear access flaps move backward, they gradually disengage from the PU rubber rollers. At the same time, the elastic force of the spring causes the bin door to bounce continuously, and the bin door rises to close the inlet.

[0017] The present utility model can open or close the inlet according to the detection needs. The opening and closing processes are stable, the structural principle is simple, and the space is saved.

[0018] The following will describe the present utility model in detail with reference to the accompanying drawings and embodiments. Description of the Drawings

[0024] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0025] As Figures 1 - 4As shown together, the present utility model provides a structure for lifting and switching a warehouse door, which includes a warehouse door 3. The warehouse door 3 is located above the bottom shell 2 and inside the front shell 1. The warehouse door 3 cooperates with the front and rear access stoppers 4 and the spring 9 to achieve lifting, and the warehouse door 3 opens and closes the access slots on the front shell 1 during the lifting process.

[0026] The front shell 1 and the bottom shell 2 are vertically arranged. A plurality of access slots are transversely opened on the front shell 1, and the plurality of access slots are equidistantly arranged. The access slots are used for inserting reagent cards.

[0027] A plurality of PU rubber rollers 8 are installed at the end of the warehouse door 3 away from the front shell 1. The plurality of PU rubber rollers 8 are equidistantly arranged, and the PU rubber rollers 8 are rotatably connected to the warehouse door 3 through a pin shaft 7.

[0028] The PU rubber rollers 8 are in rolling connection with the front and rear access stoppers 4. One side of the front and rear access stoppers 4 close to the PU rubber rollers 8 is inclined. The front and rear access stoppers 4 contact and press down the PU rubber rollers 8 during the lateral movement, and then press down the warehouse door 3.

[0029] Two symmetrically arranged guiding bearings 6 are fixed inside the warehouse door 3. A guiding column 5 arranged in the vertical direction passes through the guiding bearings 6, and the bottom end of the guiding column 5 is fixedly connected to the bottom shell 2. The cooperation of the guiding bearings 6 and the guiding column 5 ensures the vertical lifting of the warehouse door 3.

[0030] Two symmetrically arranged springs 9 are further installed between the warehouse door 3 and the bottom shell 2. The two springs 9 are located outside the two guiding bearings 6, and the springs 9 and the guiding bearings 6 are in the same plane. The restoring force of the springs 9 provides power for the upward movement of the warehouse door 3.

[0031] A limiting strip 10 is provided on the inner wall of the front shell 1. The limiting strip 10 is transversely arranged, and the limiting strip 10 limits the upper high point of the upward movement of the warehouse door 3.

[0032] The specific working principle of the present utility model:

[0033] When the front and rear access stoppers 4 move forward to contact the PU rubber rollers 8, the warehouse door 3 and the guiding bearings 6 move downward along the guiding column 5, and the warehouse door 3 descends, thereby opening the access slots on the front shell 1; when the front and rear access stoppers 4 move backward, the front and rear access stoppers 4 gradually separate from the PU rubber rollers 8. At the same time, the elastic force of the springs 9 causes the warehouse door 3 to continuously bounce up, and the warehouse door 3 ascends, thereby closing the access slots on the front shell 1. By providing the limiting strip 10 on the inner wall of the front shell 1, the upper high point of the upward movement of the warehouse door 3 is limited.

[0034] The above is an example of the best implementation mode of the present utility model. The parts not described in detail are all common general knowledge of those of ordinary skill in the art. The protection scope of the present utility model shall be subject to the content of the claims. Any equivalent transformation based on the technical inspiration of the present utility model shall also be within the protection scope of the present utility model.
