DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0023] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A sampler for anti-pollution pathogenic microorganism detection includes a sampling platform 2, a symmetrically distributed side plate 1 is fixed on the top of the sampling platform 2, a movable plate 6 is arranged between the side plates 1, the movable plate 6 is connected with a translation mechanism 3, the translation mechanism 3 is used to drive the movable plate 6 to move horizontally, a support plate 7 is arranged below the movable plate 6, a lifting mechanism 4 is arranged between the support plate 7 and the movable plate 6, the lifting mechanism 4 is used to drive the support plate 7 to move up and down, a first clamping plate 8 and a second clamping plate 9 are arranged below the support plate 7, a connecting column 10 is fixed on the top of the first clamping plate 8, the connecting column 10 is fixedly connected to the support plate 7, the second clamping plate 9 is slidably connected to the support plate 7, a fixing mechanism 5 is arranged on the inner side of the first clamping plate 8, the fixing mechanism 5 is used to fix the second clamping plate 9, so that the first clamping plate 8 and the second clamping plate 9 can clamp the cotton swab.
[0024] In this embodiment, when the sampler samples pathogenic microorganisms, the culture dish and the sampling tube containing the pathogenic microorganisms are placed on the top of the sampling platform 2. In order to improve the stability of the culture dish and the sampling tube and facilitate the positioning of the culture dish and the sampling tube, a limiting sleeve is fixed on the top of the sampling platform 2 and a placement groove is opened. When sampling, the culture dish can be placed in the placement groove, and the sampling tube can be placed in the limiting sleeve. After the culture dish and the sampling tube are placed, the cotton swab is placed between the first clamping plate 8 and the second clamping plate 9. , and then push the second clamping plate 9 to make the second clamping plate 9 move towards the first clamping plate 8 until the cotton swab is clamped between the first clamping plate 8 and the second clamping plate 9, and when the first clamping plate 8 and the second clamping plate 9 complete the clamping of the cotton swab, the fixing mechanism 5 inside the first clamping plate 8 will automatically fix the second clamping plate 9, thereby ensuring the stability of the second clamping plate 9 and improving the fixing effect of the first clamping plate 8 and the second clamping plate 9 on the cotton swab. After the cotton swab is fixed, the translation mechanism 3 drives the supporting plate 7 to move horizontally through the moving plate 6, and the supporting plate 7 The cotton swab is driven to move horizontally by the first clamping plate 8 and the second clamping plate 9. When the cotton swab moves to the top of the culture dish, the lifting mechanism 4 drives the supporting plate 7 to move downward, so that the cotton swab moves downward and enters the inside of the culture dish, thereby completing the sampling of pathogenic microorganisms. When the cotton swab completes the sampling of pathogenic microorganisms, the lifting mechanism 4 drives the supporting plate 7 to move upward, and then the translation mechanism 3 drives the movable plate 6 to move horizontally again, so that the cotton swab moves to the top of the sampling test tube. When the cotton swab moves to the top of the sampling test tube, the lifting mechanism 4 drives the supporting plate 7 to move downward again, so that the lower end of the cotton swab enters the inside of the sampling test tube. When the lower end of the cotton swab enters the inside of the sampling test tube, the fixing mechanism 5 automatically releases the fixation of the second clamping plate 9, and the second clamping plate 9 automatically resets so as to no longer clamp the cotton swab. The cotton swab with pathogenic microorganisms automatically falls into the inside of the sampling test tube. The entire sampling process does not require manual operation, which reduces the possibility of contact between staff and pathogenic microorganisms, protects the staff, and also avoids contamination of pathogenic microorganisms, thereby ensuring the accuracy of subsequent test results.
[0025] See also Figure 1 The translation mechanism 3 includes a moving block 34 fixed on the top of the moving plate 6, a threaded rod 31 is rotatably connected between the side plates 1, the threaded rod 31 penetrates the moving block 34 and is threadedly connected to the moving block 34, one end of the threaded rod 31 is connected to a first rotating part 33, the first rotating part 33 is used to drive the threaded rod 31 to rotate, and a guide rod 32 is fixed between the side plates 1, the guide rod 32 penetrates the moving block 34 and is slidably connected to the moving block 34;
[0026] When sampling pathogenic microorganisms, the threaded rod 31 is driven to rotate by the first rotating part 33. The first rotating part 33 can be a motor, which is fixedly connected to the side plate 1. The threaded connection between the threaded rod 31 and the moving block 34 drives the moving plate 6 to move horizontally, so that the first clamping plate 8 and the second clamping plate 9 can drive the cotton swab to move to the culture dish and the sampling test tube in turn, wherein the guide rod 32 can play a limiting role on the moving block 34, thereby improving the stability of the moving block 34 during movement.
[0027] See also Figure 1 and Figure 2 The lifting mechanism 4 includes a limit rod 44 which is fixedly connected to the bottom of the movable plate 6 and is symmetrically distributed. The limit rod 44 passes through the support plate 7 and is slidably connected to the support plate 7. The outside of the limit rod 44 is provided with a first elastic member 45. The two ends of the first elastic member 45 are respectively fixedly connected to the support plate 7 and the movable plate 6. An extrusion component is provided between the movable plate 6 and the support plate 7, and the extrusion component is used to extrude the support plate 7;
[0028] When the first clamping plate 8 and the second clamping plate 9 move to above the culture dish or the sampling test tube, the support plate 7 is squeezed by the squeezing component, so that the support plate 7 drives the cotton swab to move downward through the first clamping plate 8 and the second clamping plate 9 and enters the culture dish or the sampling test tube. When the sampling of pathogenic microorganisms is completed, the squeezing component no longer squeezes the support plate 7, and the support plate 7 automatically resets under the action of the first elastic member 45, and the first elastic member 45 can be a spring.
[0029] See also Figure 1 The extrusion assembly includes a rotating rod 42 disposed between the support plate 7 and the movable plate 6, and an extrusion block 43 symmetrically distributed and extruding the support plate 7 is fixed to the outside of the rotating rod 42, and both ends of the rotating rod 42 are respectively rotatably connected to the two side plates 1, and one end of the rotating rod 42 is connected to a second rotating part 41, and the second rotating part 41 is used to drive the rotating rod 42 to rotate;
[0030] When the first clamping plate 8 and the second clamping plate 9 move to above the culture dish or the sampling test tube, the second rotating part 41 drives the squeezing block 43 to rotate through the rotating rod 42. The second rotating part 41 can be a motor, which is fixedly connected to the side plate 1. When the squeezing block 43 rotates to a certain extent, the squeezing block 43 squeezes the support plate 7, so that the support plate 7 drives the cotton swab downward through the first clamping plate 8 and the second clamping plate 9. As the rotating rod 42 continues to rotate, the squeezing degree of the support plate 7 by the squeezing block 43 decreases, and the support plate 7 automatically resets under the action of the first elastic member 45.
[0031] See also Figure 3The second clamping plate 9 is fixed with symmetrically distributed support rods 12 on the top, and the support plate 7 is provided with symmetrically distributed slideways 13 inside. The support rods 12 pass through the slideways 13 and are slidably connected to the slideways 13. The support blocks 11 are fixed on the tops of the support rods 12;
[0032] When fixing the cotton swab, place the cotton swab between the first clamp plate 8 and the second clamp plate 9, and then push the second clamp plate 9 to move toward the first clamp plate 8, wherein the slide 13 limits the second clamp plate 9 through the support block 11 and the support rod 12, thereby effectively improving the stability of the second clamp plate 9 during movement.
[0033] See also Figure 4 and Figure 5 The fixing mechanism 5 includes an insertion rod 52 fixedly connected to the side wall of the second clamping plate 9, the insertion rod 52 is inserted into the first clamping plate 8 and slidably connected to the first clamping plate 8, a fixing component is provided inside the first clamping plate 8, and the fixing component is used to fix the insertion rod 52, and a second elastic member 51 is provided outside the insertion rod 52, and the two ends of the second elastic member 51 are respectively fixedly connected to the first clamping plate 8 and the side wall of the second clamping plate 9;
[0034] When fixing the cotton swab, place the cotton swab between the first splint 8 and the second splint 9, and then push the second splint 9 so that the second splint 9 drives the insertion rod 52 to move toward the inside of the first splint 8. When the first splint 8 and the second splint 9 complete the clamping of the cotton swab, the fixing component inside the first splint 8 just completes the fixation of the insertion rod 52, and then plays a fixing role on the second splint 9, ensuring the fixing effect of the first splint 8 and the second splint 9 on the cotton swab. When the cotton swab is sampled and enters the sampling tube, the fixing component no longer fixes the insertion rod 52, and the second splint 9 automatically resets under the action of the second elastic member 51, and the cotton swab automatically falls off from between the first splint 8 and the second splint 9, thereby entering the sampling tube. The second elastic member 51 can be a spring.
[0035] See also Figure 5 The fixing assembly includes a slide groove arranged inside the first clamping plate 8, a block 54 is slidably connected inside the slide groove, one end of the block 54 is connected to the inner wall of the slide groove through a third elastic member 55, and the other end of the block 54 is in contact with the side wall of the insertion rod 52, and a slot 53 adapted to the block 54 is provided on the side wall of the insertion rod 52, wherein the block 54 is connected to a traction component, and the traction component is used to pull the block 54, so that the block 54 moves to the outside of the slot 53;
[0036] When the first clamping plate 8 and the second clamping plate 9 complete the clamping of the cotton swab, the block 54 is aligned with the slot 53 on the side wall of the slide rod. At this time, under the action of the third elastic member 55, the block 54 automatically enters the slot 53. The block 54 fixes the insertion rod 52 through the slot 53, and then fixes the second clamping plate 9, ensuring the fixing effect of the first clamping plate 8 and the second clamping plate 9 on the cotton swab. When the cotton swab sampling is completed and enters the sampling test tube, the traction component pulls the block 54 to the outside of the slot 53, thereby releasing the fixation of the block 54 on the insertion rod 52, wherein the third elastic member 55 can be a spring.
[0037] See also Figure 4 and Figure 5 The traction component includes a movable rod 58 that passes through the first clamping plate 8, a baffle 57 is fixed on the top of the movable rod 58, and the baffle 57 is connected to the second clamping plate 9 through a fourth elastic member 59. The baffle 57 is fixed with symmetrically distributed traction ropes 56, and the other end of the traction rope 56 extends to the inside of the slide groove and is fixedly connected to the block 54. The surface of the sampling platform 2 is fixed with an extrusion column 510 for extruding the movable rod 58;
[0038] When the cotton swab is moved to the top of the sampling test tube after sampling, the lifting mechanism 4 drives the support plate 7 to move downward. The support plate 7 moves downward and drives the movable rod 58 to move downward at the same time. When the movable rod 58 drops to a certain extent, the bottom of the movable rod 58 contacts the top of the squeezing column 510, and the squeezing column 510 squeezes the movable rod 58, so that the baffle 57 on the top of the movable rod 58 moves upward relative to the second clamping plate 9. At this time, the baffle 57 pulls the block 54 into the slot 53 through the traction rope 56, thereby releasing the fixation of the block 54 to the insertion rod 52, wherein the fourth elastic member 59 can play a resetting role on the baffle 57, and the fourth elastic member 59 can be a spring.
[0039] Working principle: When the sampler samples pathogenic microorganisms, the culture dish containing pathogenic microorganisms and the sampling test tube are placed on the top of the sampling platform 2, and the cotton swab is placed between the first clamping plate 8 and the second clamping plate 9, and then the second clamping plate 9 is pushed to make the second clamping plate 9 move toward the first clamping plate 8. When the first clamping plate 8 and the second clamping plate 9 complete the clamping of the cotton swab, the clamping block 54 automatically enters the clamping groove 53, and the clamping block 54 fixes the insertion rod 52 through the clamping groove 53, and then fixes the second clamping plate 9, ensuring The first clamping plate 8 and the second clamping plate 9 have a fixing effect on the cotton swab. After the cotton swab is fixed, the threaded connection between the threaded rod 31 and the moving block 34 drives the moving plate 6 to move horizontally, thereby driving the cotton swab to move horizontally. When the cotton swab moves to the top of the culture dish, the rotating rod 42 squeezes the supporting plate 7 through the squeezing block 43, so that the cotton swab moves downward and enters the interior of the culture dish, thereby completing the sampling of pathogenic microorganisms. When the cotton swab completes the sampling of pathogenic microorganisms, the squeezing block 43 no longer squeezes the supporting plate 7, and the supporting plate 7 automatically resets, thereby driving the cotton swab upward. The movable plate 6 then moves horizontally through the threaded connection between the threaded rod 31 and the moving block 34. When the cotton swab moves to the top of the sampling test tube, the rotating rod 42 squeezes the supporting plate 7 through the squeezing block 43 again, so that the cotton swab moves downward and enters the inside of the sampling test tube. When the cotton swab moves downward, the supporting plate 7 also drives the movable rod 58 to move downward. When the movable rod 58 drops to a certain extent, the bottom of the movable rod 58 contacts the top of the squeezing column 510, and the squeezing column 510 squeezes the movable rod 58, so that the top of the movable rod 58 is blocked. The plate 57 moves upward relative to the second clamping plate 9. At this time, the baffle 57 pulls the block 54 into the slot 53 through the traction rope 56, thereby releasing the fixation of the block 54 on the insertion rod 52. The second clamping plate 9 is automatically reset, and the cotton swab automatically falls off from between the first clamping plate 8 and the second clamping plate 9, thereby entering the sampling test tube. The entire sampling process does not require manual operation, which reduces the possibility of contact between staff and pathogenic microorganisms, protects the staff, and also avoids contamination of pathogenic microorganisms, ensuring the accuracy of subsequent test results.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
