[0029] As shown in Figures 1 to 7 An eight-pipe integral taking device, comprising a bottom plate 1 and a top plate 2, and the top plate 2 is located on the upper side of the bottom plate 1, a placing hole 11 is formed in the top of the bottom plate 1, and a reagent tube 12 is movably connected in the placing hole 11, there are multiple reagent tubes 12, and adjacent reagent tubes 12 are connected to each other through connecting ribs, a tube cover 13 is detachably installed at the top end of the reagent tube 12, a handle strap 21 is fixedly installed at the top of the top plate 2, a positioning hole 22 is formed in the bottom of the top plate 2, and the tube cover 13 is movably connected with the positioning hole 22;

[0030] A power mechanism is arranged in the middle of the top of the top plate 2 in a trapezoidal shape to provide overall power for integral taking;

[0031] Multiple clamping mechanisms for synchronously clamping eight-tube joints are slidably installed on the top of the top plate 2 and on both sides of the power mechanism. The clamping mechanisms are fixedly installed with the power mechanism.

[0032] In this implementation scheme, when it is necessary to remove the reagent tube 12 on the base plate 1, the top plate 2 is placed on the tube cap 13, so that the bottom of the supporting main plate contacts the top of the base plate 1, and the tube cap 13 is locked in the positioning hole 22. The positioning hole 22 positions multiple clamping mechanisms. At this time, when the power mechanism is pressed, the power mechanism drives multiple clamping mechanisms to move synchronously closer to the outside of the reagent tube 12 and contact the bottom of the connecting ribs on both sides of the reagent tube 12. The multiple clamping mechanisms achieve the overall clamping of the eight-tube assembly. When the tester lifts the top plate 2 with the handle strap 21, the top plate 2 achieves the overall removal of the eight-tube assembly through the clamping structure and the connecting ribs on both sides of the multiple reagent tubes 12. At the same time, during the removal process, the positioning hole 22 and the clamping mechanism work together to enhance the stability of the reagent tube 12 and the tube cap 13 when they are removed, and also prevent the tube cap 13 from being opened during the removal process, thereby avoiding the risk of nucleic acid contamination.

[0033] Specifically, the power mechanism includes a magnetic block 3, which is fixedly installed in the middle of the top of the top plate 2. Horizontal slots 31 are provided on the top of the top plate 2 and on both the left and right sides of the magnetic block 3. The horizontal slots 31 are movably engaged with movable blocks 32. A synchronization plate 33 is fixedly installed on the side of the movable block 32 away from the magnetic block 3. An assisting rod 34 is fixedly installed on the left side of the synchronization plate 33. A connecting plate 35 is movably hinged to the top of the movable block 32. A pressing block 36 is movably hinged to the top of the connecting plate 35. The pressing block 36 and the magnetic block 3 are located on the same axis.

[0034] In this embodiment, after the top plate 2 is placed on the tube cap 13 and the tube cap 13 is locked in the positioning hole 22, the pressing block 36 is pressed down to move it downward. The pressing block 36 pushes the moving blocks 32 on both sides along their corresponding horizontal slots 31 to move away from the magnetic block 3 through the connecting plates 35 on both sides. The moving blocks 32 on both sides drive their corresponding synchronous plates 33 to move away from the magnetic block 3. The synchronous plates 33 on both sides drive their corresponding multiple assisting rods 34 to move away from the magnetic block 3, so that the multiple assisting rods 34 provide power for the transmission of the clamping mechanism when they move. When the pressing block 36 moves down to fit against the top of the magnetic block 3, the multiple assisting rods 34 are fixed by the magnetic connection between the magnetic block 3 and the pressing block 36, thereby fixing the multiple clamping mechanisms. The power mechanism transmits power synchronously to the multiple clamping mechanisms in cooperation with its internal structure, so that the multiple clamping mechanisms can synchronously approach the reagent tube 12 and contact the connecting ribs on both sides.

[0035] Specifically, the clamping mechanism includes a limiting slot 4, which is located on the top of the top plate 2 and near the left side. The limiting slot 4 is slidably engaged with a limiting block 41. A power plate 42 is fixedly installed on the top of the limiting block 41. An arc-shaped slot plate 43 is fixedly installed on the rear end of the power plate 42. A pushing slot 44 is provided on the top of the top plate 2 and directly below the arc-shaped slot plate 43. A pushing slot 44 is slidably engaged with a pushing plate 45. An arc-shaped fixing plate 46 is fixedly installed on the front side of the pushing plate 45 close to the bottom. The arc-shaped fixing plate 46 is located below the connecting rib. A cylindrical clamping rod 47 is fixedly installed on the top of the pushing plate 45. The cylindrical clamping rod 47 is movably engaged with the arc-shaped slot plate 43.

[0036] In this embodiment, when the assisting rod 34 moves to the left, it pushes the limiting block 41 to move to the left along the limiting slot 4. The limiting block 41 drives the power plate 42 to move to the left, and the power plate 42 drives the arc-shaped slot plates 43 on both sides to move to the left. When the arc-shaped slot plates 43 on both sides move to the left simultaneously, they drive their corresponding cylindrical rods 47 to move closer to the limiting slot 4. The cylindrical rods 47 on both sides drive their corresponding push plates 45 to move closer to the limiting slot 4. The push plates 45 on both sides drive their corresponding arc-shaped fixing plates 46 to move closer to the reagent tube 12. The arc-shaped fixing plates 46 on both sides move to a position closer to the outside of the reagent tube 12, so that... The tops of the arc-shaped fixing plates 46 on both sides contact and cross the bottoms of the connecting ribs on both sides of the reagent tube 12. At the same time, the arc-shaped fixing plates 46 on both sides do not contact the outside of the reagent tube 12. Similarly, the working principle of the remaining arc-shaped fixing plates 46 is the same. When the handle strap 21 is lifted, the arc-shaped fixing plates 46 are driven to move upward by the cooperation of the limiting block 41 and the pushing plate 45. The arc-shaped fixing plates 46 drive the reagent tube 12 to move upward by the connecting ribs on both sides of the reagent tube 12. At the same time, the arc-shaped fixing plates 46 fix the reagent tube 12 and the tube cap 13 in cooperation with the positioning hole 22, thereby preventing the tube cap 13 from being opened during the handling process, thus avoiding the risk of nucleic acid contamination.

[0037] Specifically, a support main board is fixedly installed on both the bottom left and right sides of the top plate 2, and there is a certain distance between the top inner wall of the positioning hole 22 and the top of the tube cover 13.

[0038] In this embodiment, when the tester presses the power mechanism, the pressing force on the top plate 2 is supported by the main support board, thereby preventing the pressing force on the top plate 2 from contacting the tube cap 13, thus protecting the reagent tube 12 and the tube cap 13.

[0039] Specifically, a limiting hole is provided at the top center of the magnetic block 3, and the bottom end of the limiting hole penetrates the bottom of the top plate 2. A limiting rod is fixedly installed at the bottom center of the pressing block 36, and the limiting rod is movably engaged with the limiting hole.

[0040] In this embodiment, when the pressing block 36 is pressed down, the direction of the pressing block 36 moving downward is restricted by the limiting lever, so that the pressing block 36 can only move vertically downward.

[0041] Specifically, there are multiple clamping mechanisms, and adjacent clamping mechanisms are staggered.

[0042] In this embodiment, since the spacing between the reagent tubes 12 on the front and rear sides is limited, the space between adjacent reagent tubes 12 is perfectly utilized by staggered clamping mechanisms, while also avoiding collisions between adjacent power mechanisms during operation.

[0043] Specifically, a support disc is fixedly installed at the top of the cylindrical clamp 47, and the bottom of the support disc fits against the top of the arc-shaped clamping plate 43.

[0044] In this embodiment, the bottom of the supporting disc is attached to the top of the arc-shaped slot plate 43, thereby fixing the height position of structures such as the push plate 45 and the arc-shaped fixing plate 46.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
