Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence detection, in particular to a fluorescence detection device. Background Art

[0002] The fluorescence detection device is a device used for safety monitoring. The detection holes of the fluorescence detection device are mostly fixed in model, and usually have corresponding fixed test tubes for detection. When a large number of samples are extracted, only fixed test tubes can be used to continue the detection work. When the test tube is small, multiple detections are required. The fluorescence detection device cannot replace test tubes of different models for detection according to actual detection conditions, which makes the fluorescence detection device less flexible. At the same time, when the test tube is vibrated inside the detection device, there is a risk of the solution inside the test tube spilling. Utility Model Content

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0017] See also Figure 1-3 , a fluorescence detection device, comprising a box body 1 with a storage tank 3 provided on the top end face, a box cover 2 rotatably arranged on the top end face of the box body 1, a partition 4 fixedly arranged laterally at the opening position of the storage tank 3 and having a limiting hole 5 provided on the end face, and a positioning mechanism arranged in the storage tank 3 for fixing the position of the reagent tube 6, a testing device for performing fluorescence testing on the reagent tube 6 is provided in the storage tank 3, the positioning mechanism comprising two first clamping blocks 8 symmetrically fitted below the limiting holes 5, two second clamping blocks 9 parallelly arranged below the two first clamping blocks 8, a first linkage rod 10 rotatably connected at the middle part of the two rod bodies and rotatably connected at the top and bottom ends to the sides of the two first clamping blocks 8 and the two second clamping blocks 9 respectively, a first control component arranged on the partition 4 and controlling the top ends of the two first linkage rods 10 to move away from each other, and a second control component arranged on the bottom ends of the two first linkage rods 10 to control the two bottom ends to move closer to each other;

[0018] The two first linkage rods 10 are located between the first clamping block 8 and the second clamping block 9 , and the middle parts of the two first linkage rods 10 are rotatably connected and are arranged on the side wall of the storage tank 3 through a transversely arranged fixing rod 15 .

[0019] like Figure 1-3As shown, first, the first control component is used to control the two rotatably connected first linkage rods 10 to rotate, so that the top ends of the two first linkage rods 10 move away from each other, drive the two first clamping blocks 8 to move away from each other, and drive the two second clamping blocks 9 to move away from each other, and then pass different types of reagent tubes 6 through the limiting holes 5 into the storage tank 3, and pass the reagent tubes 6 between the two first clamping blocks 8 and the two second clamping blocks 9. After the reagent tubes 6 are passed into the storage tank 3, the second control component is controlled to drive the two first linkage rods 10 to rotate, so that the two first linkage rods 10 move away from each other. The bottom ends of the rods 10 are close to each other, which drives the two first clamping blocks 8 to approach each other and the two second clamping blocks 9 to approach each other, so that different types of reagent tubes 6 can be clamped and fixed by the two first clamping blocks 8 and the two second clamping blocks 9. The two first clamping blocks 8 and the two second clamping blocks 9 are far away from each other, and the reagent tubes 6 have an upward fixed clamping force and a downward fixed clamping force respectively, which ensures the stability of the clamping and fixing of the reagent tubes 6, can conveniently fix different types of reagent tubes 6, and ensures the stability of the fixation of the reagent tubes 6.

[0020] The first control assembly includes a control rod 7 that moves vertically and passes through the partition 4, a cross bar 17 that is arranged horizontally and fixedly connected to the bottom end of the control rod 7 through the middle side, and two third linkage rods 16 whose one end is rotatably connected to the two end ends of the cross bar 17 and the other end is rotatably connected to the two ends of the corresponding two first linkage rods 10 below. The two third linkage rods 16 are located between the cross bar 17 and the top ends of the two first linkage rods 10.

[0021] like Figure 2-3 As shown, when placing different types of reagent tubes 6 in the storage tank 3, the control rod 7 is first moved downward to drive the cross bar 17 to move downward. The two ends of the two cross bars 17 are respectively connected to the ends of the two first linkage rods 10 located below through different third linkage rods 16, that is, the top ends of the two first linkage rods 10 are driven to move away from each other, thereby driving the two first clamping blocks 8 to move away from each other, and synchronously driving the two second clamping blocks 9 to move away from each other. At this time, when the different types of reagent tubes 6 pass through the limiting holes 5 and are inserted into the storage tank 3, the control rod 7 is released again. Under the action of the second control component, the bottoms of the two first linkage rods 10 are driven to move closer to each other, so that the two first clamping blocks 8 can be controlled to move closer to each other to clamp and fix the side of the reagent tube 6 upward, and the two second clamping blocks 9 can be driven closer to each other to clamp and fix the side of the reagent tube 6 downward, so as to facilitate the stable fixation of the side surfaces of the reagent tubes 6 of different sizes, and exert upward fixing force and downward fixing force on the reagent tube 6, so as to conveniently fix the different types of reagent tubes 6 and ensure the stability of the fixation of the reagent tube 6.

[0022] The adjacent end surfaces of the two first clamping blocks 8 are provided with first clamping grooves that match the side surfaces of the reagent tube 6; the adjacent end surfaces of the two second clamping blocks 9 are provided with second clamping grooves that match the side surfaces of the reagent tube 6; rubber pads are provided on the bottom walls of the first clamping groove and the second clamping groove.

[0023] like Figure 2-3 As shown, when the reagent tube 6 is additionally fixed by two first clamping blocks 8 and two second clamping blocks 9, the rubber pad located on the bottom wall of the first clamping groove and the rubber pad located on the bottom wall of the second clamping groove fit with the side of the reagent tube 6, which on the one hand increases the friction force of clamping and fixing, and on the other hand plays a protective role on the surface of the reagent tube 6 to avoid damage to the surface of the reagent tube 6.

[0024] The second control component includes a support block 12 arranged in the storage tank 3 and located below the two second clamping blocks 9, and two second linkage rods 11 whose top ends are respectively rotatably connected to the bottom ends of the two first linkage rods 10, and the bottom ends of the two second linkage rods 11 are rotatably connected to the top end face of the support block 12; a support groove 13 matching the bottom end of the reagent tube 6 is provided on the top end face of the support block 12.

[0025] A slide rod 14 movably passes through the support block 12 , and the bottom end of the slide rod 14 is vertically fixed on the bottom wall of the storage tank 3 .

[0026] like Figure 2-3 As shown, after different models are inserted into the storage tank 3 through the limiting hole 5, when the control rod 7 is released, the bottom end of the reagent tube 6 is located in the support groove 13 opened at the top of the support block 12, and then the control rod 7 and the reagent tube 6 are released. Under the action of the gravity of the reagent tube 6, the support block 12 is driven to move downward. At this time, the two second linkage rods 11 located on the support block 12 drive the bottom ends of the two first linkage rods 10 to approach each other, thereby driving the two first clamping blocks 8 and the two second clamping blocks 9 to clamp and fix the reagent tube 6, which is convenient for stable fixation of the reagent tube 6, can conveniently fix different types of reagent tubes 6, and ensures the stability of the fixation of the reagent tube 6.

[0027] Ensure the stability of the reagent tube 6 so that it can be detected by the fluorescence detection device later.
