A partition bar 11 is provided on the upper middle side of the interior of the shell 1, and the bottom of the partition bar 11 is in contact with the magazine mechanism 5 to increase the sealing effect and realize the isolation of the left and right sides of the magazine mechanism 5, so as to form functional zoning for the magazine mechanism 5 and improve the convenience of use.

[0030] See also Figures 1-4The present invention provides a drug genomic detection kit, wherein the tube placement structure 4 includes a plate frame 41 with a circular through groove provided therein, a rectangular block 42 fixed to the rear side of the plate frame 41, a first connecting rod 43 and a second connecting rod 44 rotatably connected to the upper and lower sides of the rectangular block 42, a slide 45 rotatably connected to the rear ends of the first connecting rod 43 and the second connecting rod 44, a roller 46 rotatably connected to the side of the first connecting rod 43 close to the slide 45, a groove frame 47 wrapped around the outer surface of the roller 46, a sleeve rod 48 fixedly connected to the rear side of the rectangular block 42, and two inner rods 49 slidably connected to the left and right sides of the sleeve rod 48.

When the plate rack 41 moves forward, the roller 46 slides and connects to the transverse groove 471, the oblique groove 472 and the sunken groove 473 in turn, and the movement trajectory is controlled by the three-section guide groove. The transverse groove 471 maintains the horizontal position of the plate rack 41, and the oblique groove 472 slowly lifts the plate rack 41 to a higher position during the removal process. The sunken groove 473 is positioned and self-locked, so that the plate rack 41 remains in a fixed position when it is pulled out to the frontmost side, thereby improving the horizontal stability of the reagent tube placement.

Through independent temperature control of dual temperature zones, the two loading bodies on the left have a refrigeration effect of 4 degrees, and the two loading bodies on the right have a constant temperature effect of 37 degrees, which is suitable for different reagent storage requirements. The loading body includes a matrix with an outer wall fixed to the bin body 51. The rectangular seat 53 has a through groove 54 on the middle side of the top, and a positioning structure 55 is provided on the middle side of the interior of the rectangular seat 53. The bottom of the positioning structure 55 is connected to the support piece 56. Under the action of the positioning structure 55, the reagent tube is stably clamped on the inside, and the bottom is lifted by the positioning structure 55, forming a full-dimensional positioning and clamping effect for different reagent tubes to ensure stability during transportation. A fan 57 is fastened to the middle and lower side of the interior of the rectangular seat 53, and a solenoid valve 58 is provided below the fan 57.

It is arranged inside the cover seat 551, and the tension of the three elastic clamps 554 can be changed through the support component 555 to adapt to various reagent tube diameters, and after the longitudinal movement of the support component 555, the top contacts the bottom side of the reagent tube, thereby improving the clamping and positioning effect of the reagent tube. The angle between two adjacent ones of the three elastic clamps 554 is 120 degrees, and the upper and middle parts of the three elastic clamps 554 are inclined outward to facilitate the clamping and positioning of the reagent tube and ensure the stability of the reagent tube.

[0034] Among them, the top support assembly 555 includes a servo motor 5551 whose bottom is fastened to the cover seat 551, a screw 5552 connected to the top output end of the servo motor 5551, a spacer 5553 wrapped and rotated at the bottom of the screw 5552, an internal threaded sleeve 5554 threadedly connected to the outer surface of the screw 5552, a push frame 5555 fixedly connected to the top side of the internal threaded sleeve 5554, a vertical rod 5556 connected to the top middle side of the push frame 5555, a slide 5557 connected to the top end of the vertical rod 5556 and a support 5558 fixedly connected to the top middle side of the slide 5557.

Through the cooperation of the screw 5552 and the internal threaded sleeve 5554, the height position of the vertical rod 5556 can be accurately raised and lowered, thereby facilitating the height adjustment of the slide 5557 and the support 5558. The adjustment is carried out so that the support 5558 contacts the bottom of the reagent tube to form a supporting effect. The spacer 5553 is fixedly connected to the bottom side of the cover seat 551. The vertical rod 5556 slides through the support block 552 and the middle side of the columnar block 553 to ensure the stability of the longitudinal displacement of the vertical rod 5556. The left and right sides of the inner wall of the cover seat 551 are provided with longitudinal sliding grooves, and the left and right sides of the internal threaded sleeve 5554 are respectively inserted into and slide on the inner sides of the two sliding grooves to ensure the stability of the longitudinal displacement of the internal threaded sleeve 5554. Three arc grooves are provided inside the slide 5557, and the three arc grooves respectively wrap and slide on the outer surfaces of the three elastic clamps 554, so as to guide the three elastic clamps 554 to retract and expand synchronously through the change of the longitudinal position of the slide 5557, thereby generating different clamping forces and ensuring the stable effect of the three elastic clamps 554 on clamping the reagent tube.

[0035] The pharmacogenomics detection kit of the present invention realizes its functions through the following collaborative working mechanism:

[0036] First, modular structure linkage:

[0037] The shell 1 is designed to open and close independently on both sides of the left cover 2 and the right cover 3, so that it can be opened and closed with one hand. The tube placement structure 4 adopts a parallelogram linkage mechanism formed by a rectangular block 42, a first connecting rod 43, a second connecting rod 44 and a slide 45, and completes a three-stage movement by pulling the Z-shaped plate rack 41: when initially stored, the plate rack 41 is placed horizontally inside the shell; when pulled out, the roller 46 moves horizontally along the transverse groove 471 of the groove rack 47, and after entering the inclined groove 472, the plate rack 41 remains horizontal and moves upward and lifts; when it reaches the sunken groove 473, the roller 46 falls into the sunken groove 473, resulting in self-locking fixation, forming a stable operating platform; after the plate rack 41 is pulled out, the inner rod 49 can be further pulled out from the side of the sleeve rod 48 through the telescopic cooperation of the sleeve rod 48 and the inner rod 49, further preventing the plate rack 41 from retracting, and the reagent tube can be stably placed in the plate rack 41;

[0038] Second, dual temperature zone dynamic temperature control:

[0039] The left area of ​​the magazine mechanism 5 is equipped with a semiconductor refrigeration chip to achieve 4°C refrigeration, while the right area is maintained at a constant temperature of 37°C through a heating wire. The fan 57 drives the air flow, which is regulated by the solenoid valve 58 and forms a circulating air duct from the air outlet of the support plate 56, so that the temperature field is improved and the temperature control effect of the reagent tube clamped and positioned inside the positioning structure 55 is ensured.

[0040] Third, adaptive clamping system:

[0041] The positioning structure 55 drives the screw 5552 through the servo motor 5551, driving the internal threaded sleeve 5554 to move vertically along the slide groove, so that the arc groove of the slide 5557 slides longitudinally along the surface of the elastic clamping claw 554, thereby controlling the contraction and expansion of the elastic clamping claw. When the slide 5557 moves upward, the three elastic clamping claws 554 are tightened and contact the surface of the reagent tube to achieve radial clamping; at the same time, in the process of the upward displacement of the slide 5557, the support 5558 is synchronously displaced longitudinally, and after the support 5558 moves upward, it is supported on the bottom of the reagent tube to form axial positioning, forming a double fixing mechanism of three-point clamping + bottom support, which ensures the clamping and positioning effect of reagent tubes of different sizes.
