[0008] As a further scheme of the present invention, the rotating assembly includes: Driven gear ring, the driven gear ring is sleeved outside the sleeve, a plurality of limit blocks are fixedly installed on the inner wall circumference of the driven gear ring at equal intervals, a plurality of limit grooves matching the limit blocks are opened on the outer circumference of the sleeve at equal intervals, the limit blocks are slidably installed on the inner wall of the limit grooves, and a limit plate is fixedly installed on the outer surface of the support rod. The driven gear ring is installed between the limit plate and the support ring; Incomplete driving gear ring, a plurality of connecting rods are fixedly installed between the bottom end of the incomplete driving gear ring and the top end of the base, and the driven gear ring intermittently meshes with the incomplete driving gear ring.

[0009] As a further scheme of the present invention, the lifting assembly includes: Lifting rod, the lifting rod is fixedly installed on the outer circumference of the lifting ring, and the lifting rod penetrates through the outer surface of the support ring and is slidably installed with it. A guide post is fixedly installed on the outer surface of the end of the lifting rod away from the lifting ring; Guide sleeve ring, the guide sleeve ring is fixedly installed at the top of the base, a closed-loop guide groove is opened on the outer circumference of the guide sleeve ring, and the guide post is slidably installed on the inner wall of the closed-loop guide groove; Arc-shaped baffle, the arc-shaped baffle is fixedly installed on the inner side of the top of the guide sleeve ring, and a retaining ring corresponding to the arc-shaped baffle is fixedly installed on the outer circumference of the bottom end of the sleeve; A stopper, which is fixedly installed on the outer surface of the top end of the arc-shaped elastic clamping plate.

At this time, as the guide post continues to move, the guide post can continue to drive the sleeve and the test tube as a whole to move upwards through the lifting rod and the lifting ring, lifting the bottom of the test tube by a certain height, avoiding the bottom of the test tube from always contacting and rubbing against the base during rotation, avoiding wear or breakage of the bottom of the test tube, and extending the service life.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0019] A gene detection device includes: A test tube 2, referring to the attached Figure 1 , and the test tube 2 is used to hold the gene solution; A base 1, referring to the attached Figure 1 , 2 and 7, a rotating mechanism for driving the test tube 2 to rotate is installed on the top of the base 1. The rotating mechanism includes a turntable 4. A plurality of placement holes 5 are equidistantly penetrated in the circumferential direction on the upper surface of the turntable 4. There are four placement holes 5, and the test tube 2 can be inserted into the placement hole 5; A fluorescent agent adding mechanism, referring to the attached Figure 1, A fluorescent agent adding mechanism is installed on the top of the base 1. The fluorescent agent adding mechanism is used to add fluorescent agent into the test tube 2 to make the gene solution generate a fluorescent signal; Refer to the appendix Figure 1 , 2 , 3, 5, 6 and 8, multiple clamping mechanisms. The clamping mechanisms are used to clamp the outside of the test tube 2. Multiple clamping mechanisms are all installed at the bottom of the turntable 4 and are correspondingly installed at each placement hole 5. A rotating component and a lifting component are installed between the clamping mechanism and the base 1; A transmission cooperation is formed between the rotating component and the clamping mechanism to make the clamping mechanism rotate self - sufficiently; A transmission cooperation is formed between the lifting component and the clamping mechanism to make the lifting component still be able to lift the clamping mechanism upward by a certain height after locking the clamping mechanism; Refer to the appendix Figure 1 and 2 , A driving component is installed on the base 1. The driving component includes a stepping motor 30 fixedly installed at the bottom end of the base 1. The output end of the stepping motor 30 penetrates through the top end of the base 1 and is fixedly installed with a driving shaft 3. The top end of the driving shaft 3 is fixedly installed with the rotation center of the turntable 4.

[0020] During use, the test tube 2 filled with the gene solution is placed into the placement hole 5 corresponding to the trapezoidal lifting block 23, and the bottom end of the test tube 2 passes through the sleeve 8 so that the bottom end of the test tube 2 falls onto the top end of the trapezoidal lifting block 23 to complete the placement of the test tube 2.

[0021] Refer to the appendix Figure 1 , 2 and 7, in this embodiment, the fluorescent agent adding mechanism includes: An L - shaped plate 26, the L - shaped plate 26 is fixedly installed at the top end of the base 1. The top end of the L - shaped plate 26 is fixedly installed with a fluorescent agent storage cylinder 27 through it. The bottom end of the fluorescent agent storage cylinder 27 is fixedly installed with a discharge pipe 28 communicated with its interior. An electromagnetic valve 29 is installed on the discharge pipe 28; A weight detection unit, the weight detection unit is electrically connected with the electromagnetic valve 29; The weight detection unit includes: A weight sensor 24, the weight sensor 24 is embedded in the top of the base 1 and the installation position of the weight sensor 24 corresponds to that of the fluorescent agent storage cylinder 27.

[0022] In use, the output end of the stepping motor 30 drives the turntable 4 to rotate through the drive shaft 3, causing the turntable 4 to drive the test tube 2 to rotate 90° towards the fluorescent agent adding mechanism side by means of the placement hole 5 and the sleeve 8, so that the bottom end of the test tube 2 slowly descends along one hypotenuse of the trapezoidal lifting block 23 onto the base 1 until it moves onto the weight sensor 24, enabling the weight sensor 24 to weigh the gene solution in the test tube 2 (the weight of the test tube 2 used has been pre-weighed, and the weight weighed by the weight sensor 24 is the peeled weight after removing the test tube 2, so that the weight of the gene solution can be directly obtained). The weight of the gene solution weighed by the weight sensor 24 opens the solenoid valve 29 through an external controller, enabling the solenoid valve 29 to control the corresponding amount of fluorescent agent to be discharged from the fluorescent agent storage cylinder 27 into the test tube 2, so as to ensure the ratio of the fluorescent agent to the gene solution, enabling the gene solution to generate a stable fluorescent signal and reducing subsequent detection errors.

[0023] Refer to the appendix Figures 3 - 6 , in this embodiment, the clamping mechanism includes: Two support rods 6, which are fixedly installed at the bottom of the turntable 4, and the two support rods 6 are arranged on both sides of the placement hole 5. The bottom ends of the two support rods 6 are fixedly installed with a support ring 7. A sleeve 8 is movably installed inside the support ring 7. The sleeve 8 and the placement hole 5 are arranged on the same axis, so that the test tube 2 can vertically pass through the placement hole 5 and the sleeve 8, and the test tube 2 can be freely inserted into the sleeve 8. A plurality of arc-shaped elastic clamping plates 9 are evenly and fixedly installed in the circumferential direction at the top end of the sleeve 8, and the plurality of arc-shaped elastic clamping plates 9 are arranged in a flared shape that expands outwards; A lifting ring 10, the inner wall of the lifting ring 10 is rotatably installed with a locking ring 11, and both the locking ring 11 and the lifting ring 10 are sleeved outside the sleeve 8. An annular groove is provided on the inner wall of the lifting ring 10, and the locking ring 11 is rotatably installed in the annular groove.

[0024] After the addition of the fluorescent agent is completed, the turntable 4 continues to drive the test tube 2 and the sleeve 8 to rotate towards the excitation light source 25, so that the guide post 13 installed on the lifting rod 12 moves from the smooth section groove 141 to the lifting section groove 142, enabling the guide post 13 to jack up the lifting ring 10 through the lifting rod 12, causing the lifting ring 10 to drive the locking ring 11 to move upwards. When the guide post 13 moves to the first half position of the lifting section groove 142, the retaining ring 31 installed at the bottom end of the sleeve 8 is located below the arc-shaped baffle 21, so that when the locking ring 11 moves upwards, it will not drive the sleeve 8 to move upwards due to the resistance of the arc-shaped elastic clamping plates 9, thus affecting the clamping effect on the test tube 2; when the locking ring 11 moves upwards, it will push the plurality of arc-shaped elastic clamping plates 9 towards the test tube 2, causing the plurality of arc-shaped elastic clamping plates 9 to clamp the test tube 2, so as to subsequently drive the sleeve 8 and the test tube 2 to rotate self-rotationally through the rotating assembly, enabling the gene solution in the test tube 2 to be mixed with the added fluorescent agent and ensuring that the gene solution generates a uniform fluorescent signal.

[0025] Refer to the appendixFigure 3 , 5 and 7, in this embodiment, the rotating assembly includes: The driven gear ring 15 is sleeved outside the sleeve 8. A plurality of limiting blocks 16 are fixedly installed at equal intervals in the circumferential direction of the inner wall of the driven gear ring 15. A plurality of limiting grooves 17 matching the limiting blocks 16 are opened at equal intervals in the circumferential direction of the outer periphery of the sleeve 8. The limiting blocks 16 are slidably installed on the inner walls of the limiting grooves 17. By using the cooperation of the limiting blocks 16 and the limiting grooves 17, it can be ensured that while the driven gear ring 15 drives the sleeve 8 to rotate, the sleeve 8 can also move up and down independently. A limiting plate 22 is fixedly installed on the outer surface of the support rod 6. The driven gear ring 15 is installed between the limiting plate 22 and the support ring 7. The axial direction of the driven gear ring 15 is limited by the limiting plate 22 and the support ring 7 to prevent the sleeve 8 from driving the driven gear ring 15 to move when moving up and down, affecting the meshing effect between the driven gear ring 15 and the incomplete driving gear ring 19; The incomplete driving gear ring 19 has a plurality of connecting rods 18 fixedly installed between the bottom end of the incomplete driving gear ring 19 and the top end of the base 1. The driven gear ring 15 intermittently meshes with the incomplete driving gear ring 19; After the test tube 2 is clamped by the plurality of arc-shaped elastic clamping plates 9, the driven gear ring 15 sleeved outside the sleeve 8 will mesh with the teeth of the incomplete driving gear ring 19, enabling the driven gear ring 15 to drive the test tube 2 to rotate self - rotatably to mix the gene solution and the added fluorescent agent.

[0026] Refer to the attached Figure 3 , 6 and 8, in this embodiment, the lifting assembly includes: The lifting rod 12 is fixedly installed on the outer periphery of the lifting ring 10, and the lifting rod 12 penetrates through the outer surface of the support ring 7 and is slidably installed thereon. A guide post 13 is fixedly installed on the outer surface of the end of the lifting rod 12 away from the lifting ring 10; The guiding sleeve ring 14 is fixedly installed on the top end of the base 1. A closed - loop guide groove is opened on the outer periphery of the guiding sleeve ring 14. The closed - loop guide groove is formed by connecting a smooth section groove 141, a lifting section groove 142, and a descending section groove 143 end to end. The arc - shaped baffle 21 is correspondingly installed at the lifting section groove 142. The guide post 13 is slidably installed on the inner wall of the closed - loop guide groove; The arc - shaped baffle 21 is fixedly installed on the inner side of the top end of the guiding sleeve ring 14. A retaining ring 31 corresponding to the arc - shaped baffle 21 is fixedly installed on the outer periphery of the bottom end of the sleeve 8; The stop block 20 is fixedly installed on the outer surface of the top end of the arc - shaped elastic clamping plate 9.

[0027] When the guide post 13 moves to the tail position of the lifting section groove 142, the locking ring 11 abuts against the stopper 20 on the arc-shaped elastic splint 9 and cannot move up any further. Thus, the test tube 2 is completely clamped by multiple arc-shaped elastic splints 9, and the retaining ring 31 installed at the bottom of the sleeve 8 also moves away from below the arc-shaped baffle 21. At this time, as the guide post 13 continues to move, the guide post 13 can drive the sleeve 8 and the test tube 2 as a whole to continue moving up through the lifting rod 12 and the lifting ring 10, lifting the bottom of the test tube 2 by a certain height, preventing the bottom of the test tube 2 from continuously contacting and rubbing against the base 1 during self-rotation, avoiding wear or breakage of the bottom of the test tube 2, and extending its service life.

[0028] Refer to the appendix Figure 2 and 7 In this embodiment, an excitation light source 25 (such as ultraviolet light) is embedded at the top of the base 1, and the excitation light source 25 is correspondingly installed at the lifting section groove 142 and the descending section groove 143.

[0029] While the test tube 2 is rotating, the excitation light source 25 embedded at the top of the base 1 can irradiate the gene solution and the fluorescent agent in the test tube 2 (the test tube 2 is made of glass to ensure the light transmission effect), enabling the excitation light source 25 to excite the fluorescent markers in the gene solution, so that subsequent fluorescence signals can be used by a fluorescence microscope to analyze the presence, concentration, or other characteristics of the target gene. For amplification experiments such as PCR, the number of target genes can be calculated through the threshold value (CT value) of the fluorescence signal.

[0030] Refer to the appendix Figure 2 and 7 In this embodiment, a jacking assembly is installed at the top of the base 1. The jacking assembly includes a trapezoidal jacking block 23 fixedly installed at the top of the base 1. The trapezoidal jacking block 23 is correspondingly installed at the smooth section groove 141. A sponge pad is bonded to the top of the trapezoidal jacking block 23 to buffer the bottom of the test tube 2 when it lands on the top of the trapezoidal jacking block 23, preventing the test tube 2 from making hard contact with the top of the trapezoidal jacking block 23 and damaging the test tube 2.

[0031] When the guide post 13 returns from the descending section groove 143 to the smooth section groove 141, the test tube 2 is moved to the other inclined side of the trapezoidal jacking block 23, and the bottom of the test tube 2 will be re-lifted along the inclined side to the top of the trapezoidal jacking block 23, exposing the upper part of the test tube 2 above the top of the turntable 4, facilitating the removal of the test tube 2.

[0032] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
