When the test tube 20 is filled with the test reagent, the arc-shaped rack 31 is combined to effectively improve the mixing effect of the test tube 20 in the test tube rack 21, thereby improving the reaction rate between the test reagent and the intestinal bacteria.

[0035] Further, such as Figure 6 As shown, the rotary drive assembly includes a concentric frame 32 arranged at the bottom of the test tube rack 21, and an annular clamping groove 33 is arranged in the concentric frame 32. A matching pulley 34 is arranged at one end of the connecting bent rod 35 located in the annular clamping groove 33. The matching pulley 34 is slidably mounted with the annular clamping groove 33. A mounting plate 37 is arranged on the connecting bent rod 35, and a driving motor 38 is fixedly mounted on the mounting plate 37. The driving motor 38 is connected to a matching gear 1 39. The inner ring of the concentric frame 32 is provided with an inner gear ring 320, and the matching gear 1 39 and the inner gear ring 320 are meshed with each other.

[0036] Specifically, by arranging a concentric frame 32 at the bottom of the test tube rack 21, wherein the connecting curved rod 35 is slidably installed in combination with the matching pulley 34 and the annular clamping groove 33 in the concentric frame 32, the test tube rack 21 can be freely installed, and the rotary centrifugal drive of the test tube rack 21 can be realized at the same time, and it is convenient to control the test tubes 20 on the test tube rack 21 to be filled with test reagents in sequence. By arranging a mounting plate 37 on the connecting curved rod 35, and then installing a driving motor 38 and a matching gear 1 39, when the test tube rack 21 rotates in space along the arc frame 31, the test tube rack 21 can be driven to rotate at any position in combination with the driving motor 38 and the matching gear 1 39.

[0038] Specifically, the test tube rack 21 needs to be kept horizontal when installing the test tube 20 and filling the test reagent. By setting an annular rack 40 on the storage plate 2, the driving gear 42 set on the outer ring of the annular rack 40 is engaged with the outer gear ring 41. When the annular rack 40 rotates, it drives the connecting rack 44 and the rotating rack 43 to rotate, so that the end of the rotating rack 43 is pressed on the upper end of the test tube rack 21, so that the test tube rack 21 and the storage plate 2 are kept horizontal, which is convenient for installing the test tube 20 and filling the test reagent into the test tube 20.

[0039] Further, such as Figure 8 As shown, a ball 46 is provided at one end of the rotating frame 43 facing the test tube rack 21, and the ball 46 is vertically inserted into the rotating frame 43. A tensioning spring 47 is provided between the ball 46 and the rotating frame 43. An annular groove 211 is provided on the test tube rack 21, and the sizes of the ball 46 and the annular groove 211 match each other.

[0040] Specifically, in order to reduce the resistance encountered by the test tube rack 21 during the rotational movement when the rotating frame 43 moves to the upper surface of the test tube rack 21, a ball 46 is provided at the end of the rotating frame 43 and is tensioned and installed in combination with a tensioning spring 47. When the ball 46 moves with the rotating frame 43 and falls into the annular groove 211, the test tube rack 21 is horizontally positioned. At the same time, the resistance between the test tube rack 21 and the ball 46 is greatly reduced when the test tube rack 21 rotates driven by the rotary drive assembly.

[0041] Further, such as Fig. 9 , Fig.10 As shown, the reagent filling mechanism 5 includes a right-angle frame 50 arranged on the storage plate 2, a reagent cartridge 51 is arranged on the right-angle frame 50, a filling needle 52 is installed on the reagent cartridge 51 for lifting, an adjustment slot 54 is arranged on the right-angle frame 50, a matching slider 55 is slidably installed in the adjustment slot 54, a telescopic motor 53 is arranged on the right-angle frame 50, and the telescopic motor 53 is connected to the matching slider 55, a connecting column 57 is arranged at the bottom of the right-angle frame 50, a sliding frame 58 is slidably installed on the connecting column 57, a push-pull rod 56 is rotatably installed between the end of the sliding frame 58 and the matching slider 55, and the sliding frame 58 is clamped with the filling needle 52.

[0042] Specifically, when the test tube 20 rotates to the bottom of the reagent filling mechanism 5 along with the test tube rack 21, the telescopic motor 53 controls the sliding block 55 to move forward, and the push-pull rod 56 is combined to make the sliding frame 58 move downward along the connecting column 57, thereby driving the filling needle 52 to move downward, piercing the rubber stopper on the test tube 20, and filling the test tube 20 with the reagent.

[0043] Further, such as Fig.10As shown, a mounting column 59 is inserted into the sliding frame 58, and a pressing frame 511 is provided at the end of the mounting column 59. The pressing frame 511 cooperates with the rubber plug on the test tube rack 21, and the part of the mounting column 59 located between the sliding frame 58 and the pressing frame 511 is sleeved with a supporting spring 510.

[0044] Specifically, in order to ensure that the rubber stopper will not be detached from the end of the inspection test tube 20 before and after filling, before filling, the sliding frame 58 is first combined with the supporting spring 510 to move the pressing frame 511 downward to press on the rubber stopper, and then the filling needle 52 contacts and pierces the rubber stopper to perform the filling operation. After the filling is completed, the sliding frame 58 is retracted, and the filling needle 52 is detached before the rubber stopper, and then the pressing frame 511 is detached from the rubber stopper, thereby avoiding the rubber stopper and the inspection test tube 20 being separated when the filling needle 52 is detached.

[0045] Further, such as Fig.11 As shown, the centrifugal posture control mechanism 6 includes a center rod 60 arranged at the end of the right-angle frame 50, and the end of the center rod 60 is connected to a positioning ball 2 61, and the positioning ball 2 61 and the positioning ball 1 30 are distributed on the same vertical axis. A cross 62 is installed on the outer side of the positioning ball 2 61 for rotation. The end of the right-angle frame 50 is annularly distributed around the center rod 60 as the center, and the end of the electric telescopic rod 65 is connected to a ball joint 1 64. A snap-on ring frame 63 is slidably installed on the cross 62, and the ball joint 1 64 is fixedly connected to the snap-on ring frame 63. A plurality of ball joints 2 66 are arranged at the bottom of the cross 62, and the ball joint 2 66 is connected to a connecting rod 68, and the connecting rod 68 is connected to a ball joint 3 67. The ball joint 3 67 is annularly distributed and installed on the upper surface of the test tube rack 21.

[0046] Specifically, in order to flexibly control the rotary centrifugal posture of the test tube rack 21, the clamping ring rack 63 is installed through multiple sets of electric telescopic rods 65 and ball joints 1 64, and the lengths of the electric telescopic rods 65 are controlled respectively to adjust the inclination angle of the clamping ring rack 63, thereby adjusting the inclination angle of the cross 62. The cross 62 is connected to the test tube rack 21 through the ball joint 2 66, the connecting rod 68 and the ball joint 3 67, thereby driving the test tube rack 21 to tilt synchronously. Combined with the rotary drive assembly, the test tube rack 21 performs centrifugal movement at a specific inclination angle, driving the test tube 20 to be fully mixed with the detection reagent.

[0047] A method for using the above-mentioned kit for intestinal bacteria gene detection includes the following steps: S1, packing the cultured intestinal bacteria samples into multiple groups of detection test tubes 20, plugging the ports of the detection test tubes 20 with rubber plugs, and distributing and installing the detection test tubes 20 on a test tube rack 21; S2, positioning the test tube rack 21 through a positioning mechanism 4, adding reagents to the detection test tubes 20 on the test tube rack 21 in combination with a reagent filling mechanism 5, and driving the test tube rack 21 to rotate in combination with a rotary drive component to achieve sequential reagent filling of the detection test tubes 20; S3, the test tube rack 21 filled with the detection reagent performs high-speed rotary centrifugal motion through a rotary drive component, and at the same time adjusts the pitch angle of the test tube rack 21 in combination with a centrifugal posture control mechanism 6, driving the detection test tubes 20 to fully centrifugally shake.

[0048] The working principle of the embodiment of the present invention is:

[0049] like Figure 1-Figure 11As shown, a plurality of arc-shaped racks 31 form a spherical structure, and the test tube rack 21 moves in the arc-shaped slide groove 310 in combination with the connecting curved rod 35 and the matching ball 36, thereby realizing the free rotation of the test tube rack 21 in space. When the test tube 20 is filled with the detection reagent, the arc-shaped rack 31 is combined to effectively improve the mixing effect of the test tube 20 in the test tube rack 21, thereby improving the reaction rate between the detection reagent and the intestinal bacteria. By setting a concentric rack 32 at the bottom of the test tube rack 21, wherein the connecting curved rod 35 is combined with the matching pulley 34 and the annular clamping groove 33 in the concentric rack 32 for sliding installation, the test tube rack 21 is free to be installed, and the rotary centrifugal drive of the test tube rack 21 can be realized at the same time, and it is convenient to control the test tubes 20 on the test tube rack 21 to be filled with the detection reagent in sequence. By setting a mounting plate 37 on the connecting curved rod 35, and then installing a driving motor 38 and a matching gear 39, when the test tube rack 21 rotates in space along the arc frame 31, the driving motor 38 and the matching gear 39 can be combined at any position to drive the test tube rack 21 to perform a rotary motion. When installing the test tube 20 and filling the test reagent, the test tube rack 21 needs to be kept in a horizontal state. By setting an annular frame 40 on the storage plate 2, the driving gear 42 set on the outer ring of the annular frame 40 is meshed with the outer gear ring 41. When the annular frame 40 rotates, it drives the connecting frame 44 and the rotating frame 43 to rotate, so that the end of the rotating frame 43 is pressed on the upper end of the test tube rack 21, so that the test tube rack 21 and the storage plate 2 are kept in a horizontal state, which is convenient for installing the test tube 20 and filling the test reagent on the test tube 20. In order to reduce the resistance of the test tube rack 21 during the rotation when the rotating rack 43 moves to the upper surface of the test tube rack 21, a ball 46 is arranged at the end of the rotating rack 43 and is tensioned and installed in combination with a tension spring 47. When the ball 46 moves with the rotating rack 43 and falls into the annular groove 211, it plays a role in horizontal positioning of the test tube rack 21. At the same time, the resistance between the test tube rack 21 and the ball 46 is greatly reduced when the test tube rack 21 rotates under the drive of the rotary drive assembly. When the test tube 20 rotates to the bottom of the reagent filling mechanism 5 with the test tube rack 21, the telescopic motor 53 controls the sliding block 55 to move forward, and the push-pull rod 56 is combined to make the sliding frame 58 move down along the connecting column 57, thereby driving the filling needle 52 to move downward, piercing the rubber stopper on the test tube 20, and filling the test tube 20 with the reagent. In order to ensure that the rubber stopper will not be separated from the end of the inspection test tube 20 before and after filling, before filling, the sliding frame 58 is first combined with the supporting spring 510 to move the pressing frame 511 downward to press on the rubber stopper, and then the filling needle 52 contacts and pierces the rubber stopper to perform the filling operation. After the filling is completed, the sliding frame 58 is retracted, and the filling needle 52 is separated from the rubber stopper first, and then the pressing frame 511 is separated from the rubber stopper, thereby avoiding the rubber stopper and the inspection test tube 20 being separated when the filling needle 52 is separated.
