[0028] Embodiment 2

[0029] like Figure 2-Figure 5 As shown, the present invention proposes a reading device for a fluorescence chromatography rapid test reagent. Compared with the first embodiment, the present embodiment records the detailed structures of the on-off component and the light shielding component. The on-off component includes a shaped plate 12, an elastic member 13 and a power supply 14. The shaped plate 12 is connected to the accommodating cavity opened in the middle position of the reading box 1, and the power supply 14 is connected between the shaped plates 12;

[0030] In an optional embodiment, the power source 14 is three button batteries 15 connected in series; after the button batteries 15 are connected in series, their voltage increases to reach the voltage intensity required by the LED lamp 4 .

[0031] The bottom of the power supply 14 is used to contact one end of the elastic member 13, and the other end of the elastic member 13 is connected to the]-shaped plate 12; the elastic member 13 uses a tower spring, which can drive the power supply 14 to move over a larger range in a smaller space when compressed by external force, so as to keep it away from the LED lamp 4 to cut off the circuit.

[0032] The shading assembly includes a shading plate 16 and an extrusion block 18. The shading plate 16 is slidably connected in a sliding groove 17 opened on the interpretation box 1, and the two sides of one end of the shading plate 16 are slidably connected with the ]-shaped plate 12 and the battery respectively; a through hole is opened at one end of the shading plate 16 to facilitate pulling the shading plate 16 to move; the lower surface of the shading plate 16 is connected to the symmetrically arranged extrusion block 18, and the extrusion block 18 is slidably connected with the extrusion groove 19 opened on the sliding groove 17; the extrusion block 18 is provided with a beveled edge near one end of the on-off assembly to facilitate the extrusion block 18 to be inserted into the gap between the button battery 15 and the ]-shaped plate 12.

The shading plate 16 blocks the observation slot 3 on the reading box 1, and the extrusion block 18 connected below the shading plate 16 is inserted into the extrusion groove 19. The extrusion block 18 contacts the top of the power supply 14 composed of the button batteries 15 connected in series during the movement.

After the elastic member 13 is compressed, the power supply 14 moves down away from a pin of the LED lamp 4, and the circuit of the LED lamp 4 is disconnected. When the fluorescent reagent card reaction is completed and needs to be observed, the shading plate 16 is pulled to move it out of the sliding groove 17. After the power supply 14 loses external force compression, the elastic member 13 automatically resets and drives the power supply 14 to rise. The power supply 14 contacts the pin of the LED lamp 4 to connect the circuit. At this time, the fluorescent reagent card can be observed through the observation slot 3.
