[0020] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0021] According to Figure 1 , 2 , as shown in Figures 3 and 4, in this embodiment, a reagent card positioning device for a dry fluorescence immunoassay analyzer is proposed, which includes a base plate 1 and an insertion plate 5. The insertion plate 5 is inserted into a slot 3 opened on the front surface of the base plate 1, and the insertion plate 5 is slidably connected to the slot 3. A buckle structure for locking the insertion plate 5 is provided inside the slot 3;

[0022] A storage frame 6 is provided at the upper end of the insertion plate 5. The storage frame 6 is fixedly connected to the insertion plate 5. An opening is provided on the front surface of the storage frame 6. Two rubber clamping blocks 12 are provided inside the storage frame 6. A gap allowing a reagent card to be placed is left between the two rubber clamping blocks 12; The reagent card to be tested is assembled into the storage frame 6 from the front surface of the storage frame 6 by means of plugging and unplugging. The insertion plate 5 is fixed at the lower end of the storage frame 6 and is also assembled into the slot 3 opened on the front surface of the base plate 1 by means of plugging and unplugging. The split connection structure makes it easy for the staff to replace and maintain each component of the positioning device.

[0023] Two fixed seats 8 are provided at the upper end of the base plate 1. The fixed seats 8 are placed on both sides of the storage frame 6. The fixed seats 8 are detachably connected to the base plate 1. A wedge mechanism for pushing the two rubber clamping blocks 12 to approach each other is provided on the side of the fixed seat 8 facing the storage frame 6. The wedge mechanism is movably matched with the rubber clamping blocks 12. After the insertion plate 5 is completely pushed into the slot 3, the two fixed seats 8 at the upper end of the base plate 1 will push the two rubber clamping blocks 12 inside the storage frame 6 to close through the wedge mechanism. When the two rubber clamping blocks 12 close, they will clamp the reagent card inserted into the storage frame 6, avoiding the small-sized reagent card from shaking inside the storage frame 6, with strong reliability.

[0024] Regarding the fixation between the fixed seat 8 and the base plate 1: A plurality of fixing bolts are assembled at the upper end of the fixed seat 8. The fixing bolts pass through the fixed seat 8 and are threadedly connected to the bolt holes opened on the upper end surface of the base plate 1. When the rubber clamping blocks 12 are not used to fix the reagent plate, the fixing bolts assembled at the upper end of the fixed seat 8 are screwed out from the bolt holes on the upper end surface of the base plate 1, and then the fixed seat 8 can be removed from both sides of the storage frame 6.

[0025] To improve the stability of the plug board 5 when it is inserted into and pulled out of the slot 3, T-shaped sliders 14 are provided on both sides of the plug board 5. The T-shaped sliders 14 are fixedly connected to the plug board 5 and are slidably connected to T-shaped chutes 4 opened on the front surface of the bottom plate 1. The T-shaped chutes 4 are disposed on both sides of the slot 3 and communicate with the slot 3. When the plug board 5 is inserted into the slot 3, the T-shaped sliders 14 fixed on both sides of the plug board 5 will also be inserted into the T-shaped chutes 4. Through the cooperation of the T-shaped sliders 14 and the T-shaped chutes 4, the plug board 5 is limited, and the plug board 5 will not deflect when sliding along the slot 3.

[0026] Regarding the inclined wedge mechanism: The inclined wedge mechanism includes a first inclined wedge block 9 and a second inclined wedge block 13. The first inclined wedge block 9 is fixedly connected to one side of the fixed seat 8 facing the storage frame 6. The second inclined wedge block 13 is disposed between the storage frame 6 and the first inclined wedge block 9. One end of the second inclined wedge block 13 is fixedly connected to the rubber clamping block 12, and the other end of the second inclined wedge block 13 is slidably engaged with the fixed seat 8. The rubber clamping block 12 passes through the storage frame 6 and is slidably connected to the storage frame 6. A spring return assembly is provided at the connection between the storage frame 6 and the rubber clamping block 12. When the plug board 5 is pushed into the slot 3, the first inclined wedge block 9 moves between the two fixed seats 8. The first inclined wedge block 9 on the fixed seat 8 will be in contact with the second inclined wedge blocks 13 on both sides of the storage frame 6. The first inclined wedge block 9 slides along the inclined surface on the second inclined wedge block 13 and pushes the second inclined wedge block 13. When the two second inclined wedge blocks 13 move, they will push the two rubber clamping blocks 12 closer together to clamp the reagent plate inserted into the storage frame 6.

[0027] After the plug board 5 is pulled outwards, the second inclined wedge blocks 13 on both sides of the storage frame 6 are removed from between the two first inclined wedge blocks 9, and the spring return assembly will push the two rubber clamping blocks 12 back to their original positions. Specifically, the spring return assembly includes an activity groove 15 opened on the inner side of the storage frame 6. An activity ring 16 and a plurality of activity grooves 15 are provided in the activity groove 15. The activity ring 16 is slidably connected to the activity groove 15. The activity ring 16 is sleeved outside the rubber clamping block 12 and is fixedly connected to the rubber clamping block 12. One side of the activity ring 16 away from the fixed seat 8 is fixedly connected to a spring 17. One end of the spring 17 away from the activity ring 16 is also fixedly connected to the inner wall of the activity groove 15. When the two rubber clamping blocks 12 approach, the activity ring 16 will slide along the activity groove 15 to compress the spring 17. When the thrust received by the second inclined wedge block 13 disappears, the activity ring 16 will be pushed by the spring 17 to reset the rubber clamping block 12.

[0028] After the plug board 5 is completely pushed into the slot 3, the buckle structure will lock the plug board 5 in the slot 3. The buckle structure includes a plurality of rubber balls 10 provided on the back surface of the plug board 5. The rubber balls 10 are fixedly connected to the plug board 5 and are buckled to the storage frame 6 opened on the inner side of the slot 3. After the plug board 5 is completely pushed into the slot 3, the rubber balls 10 on the back surface of the plug board 5 will be buckled into the card slots 7 opened on the inner side of the slot 3 to prevent the plug board 5 from falling out of the slot 3.

[0029] To facilitate the staff to pull out the plug board 5 from the slot 3, a handle 11 is provided at one end of the plug board 5 away from the rubber ball 10. The handle 11 is fixedly connected to the plug board 5, and a rubber sheath is sleeved outside the handle 11. The rubber sheath can increase the friction between the handle 11 and the hand and improve the comfort when holding.

[0030] Working principle: The reagent card for detection is assembled into the storage frame 6 from the front of the storage frame 6 by means of plugging and unplugging. The plug board 5 is fixed at the lower end of the storage frame 6 and is also assembled into the slot 3 opened on the front of the bottom plate 1 by means of plugging and unplugging. After the plug board 5 is completely pushed into the slot 3, the two fixing seats 8 at the upper end of the bottom plate 1 will push the two rubber clamping blocks 12 inside the storage frame 6 to close through the wedge mechanism. When the two rubber clamping blocks 12 close, they will clamp the reagent card inserted into the storage frame 6 to prevent the small-sized reagent card from shaking inside the storage frame 6, with strong reliability.
