Description

Technical Field

[0001] This invention relates to the field of microbial detection and analysis instruments, specifically to a microbial detection and analysis instrument with a replaceable slice tray structure. Background Technology

[0002] Microbial detection and analysis instruments are a class of devices used to detect and analyze the presence and activity of microorganisms. These instruments can be applied in various fields, such as medicine, food safety, and environmental protection. The main function of microbial detection and analysis instruments is to detect and analyze the presence and activity state of microorganisms in order to determine their biological characteristics and help people better understand the distribution and impact of microorganisms in different environments.

[0003] Existing microbial detection and analysis instruments have some shortcomings in use. For example, CN114058490A discloses a microbial detection and analysis instrument that facilitates slicing analysis. This instrument, through the cooperation of a pressure rod and a locking block, can fix the culture plate when slicing microbial targets, preventing the nutrients on the culture plate from being in a jelly-like state during slicing, thus improving the accuracy of the slice. When the locking block is pressed, it contacts the surface of the culture plate. After the internal slider is compressed, the internal insertion cone, under the bending action of the bending rod, inserts and fixes the nutrients, raising the height of the culture plate's sides in preparation for subsequent microbial slicing. Although the above device can achieve the slicing function, it cannot place multiple samples at once for comparative testing. Furthermore, existing microbial detection and analysis instruments cannot adapt to different sample adjustment tray structures, nor can they switch between trays and test tubes. Furthermore, existing detection and analysis instruments cannot switch between modifying bacterial community structure and adjusting tray position, or can perform the modification of bacterial community structure and adjustment of tray position simultaneously, and cannot uniformly mix liquid or semi-solid samples. Summary of the Invention

[0004] In view of the problems existing in current microbial detection and analysis instruments, this invention is proposed.

[0008] As a preferred embodiment of the present invention, the first connecting pipe, the second connecting pipe, the third connecting pipe, the fourth connecting pipe and the support plate are nested, and the lower surface of the fourth connecting pipe is flush with the lower surface of the support plate.

[0009] As a preferred embodiment of the present invention, the top plate forms a sliding structure with the outer shell through a limiting groove and a connecting block, the inner wall of the limiting groove and the outer wall of the connecting block are in contact with each other, and the height of the top surface of the inner wall of the outer shell is greater than the height of the bottom surface of the detection rod.

[0010] As a preferred embodiment of the present invention, the support assembly includes a connecting block fixedly installed on the outside of the second connecting pipe, a traction steel rope fixedly connected above the connecting block, the top end of the traction steel rope being guided by a guide wheel and connected to a winding wheel, the guide wheel and the winding wheel being rotatably installed inside the first connecting pipe, a support plate fixedly connected to the outside of the winding wheel, and storage slots for storing the support plate being provided around the outside of the first connecting pipe, the rotation range of the support plate being 0-90°, and the lower surface of the support plate being in contact with the upper surface of the support frame.

[0013] As a preferred embodiment of the present invention, the second rotating rod and the first rotating rod form a rotating structure with the second fixed sleeve and the first fixed sleeve through a rotating ring and a damping pad. The inner wall of the damping pad is provided with longitudinal ridges. The first inner rod forms a sliding structure with the first rotating rod and the push block through a first sliding sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The device is equipped with a conveyor belt, a moving plate, and side plates, which allow for manual adjustment of the position of the conveyor belt surface support components. It can also be driven by a motor to operate the conveyor belt, facilitating subsequent comparative testing and improving the ease of use of the device. This solves the problem that existing microbial detection and analysis instruments cannot place multiple samples for comparative testing at the same time.

[0016] 2. Through the nested support components on the device, the first, second, third, and fourth connecting tubes can be expanded or contracted. When each connecting tube is expanded, the device is in a sealed state, allowing it to be used as a test tube. When each connecting tube is retracted, the device can be used as a tray, improving the adjustability of the device. This solves the shortcomings of existing microbial detection and analysis instruments that cannot adapt to different sample adjustment trays and cannot switch between trays and test tubes. This device has the advantage of higher adjustability.

[0017] 3. Through the set mixing and adjustment components, the mixing component can fully stir and mix the mixed liquid or semi-solid sample in the support component. When using the mixing function, simply press down the protruding part on the outside of the second sliding sleeve to allow the stirring rod to be placed inside the support component for sample stirring. When pressing down the protruding part on the outside of the first sliding sleeve, the first inner rod and the push block are connected in a keyed manner, allowing the push block to precisely adjust the position of the sample. This allows the device to switch between modifying the bacterial community structure and adjusting the position of the support tray, or to modify the bacterial community structure and adjust the position of the support tray simultaneously, thus improving the functionality of the device.

[0018] 4. The movable plate allows the device to open or close the opening at the top of the outer casing, and the position of the movable plate can also be adjusted. This allows the device to use the movable plate as a reference for more accurate analysis and testing during the test. At the same time, the detection rod on the rear of the device allows the device to detect the height of the support component before the sample is fed in, so as to avoid the support component from bumping into the outer casing and causing it to tip over, thus improving the safety of the device during use.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0036] Example

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] like Figures 1-12As shown, a microbial detection and analysis instrument with a replaceable slice tray structure includes a base plate 1. A side plate 2 is fixedly connected to the upper surface of the base plate 1. A connecting groove 3 is formed inside the side plate 2. A movable plate 4 is slidably installed inside the connecting groove 3. A motor 5 is fixedly installed on the surface of the movable plate 4. A conveyor belt 6 is installed on the left side of the motor 5. The motor 5 drives the conveyor belt 6. The initial position of the conveyor belt 6 is adjusted via the movable plate 4 and the connecting groove 3 for subsequent comparative detection. An extension plate 7 is fixedly connected to the outside of the motor 5. Fixed plates 16 are fixedly connected to the left and right sides of the base plate 1. A cover plate 17 is hinged to the top of the fixed plates 16. A support frame 18 is attached to the side of the fixed plate 16 near the base plate 1. A support rod 19 is fixedly connected to the bottom of the support frame 18. The support rod 19 and the base plate 1 are fixedly connected. Support components 8 are placed on the surface of the conveyor belt 6 and the surface of the support frame 18. A support component 20 is installed on the right side of the support component 8. After the support component 8 is placed on the surface of the support frame 18, it can be used as a test tube after unfolding. After the support component 8 is unfolded, the support component 20 can automatically unfold. After the support component 8 is stored, it can be placed on the surface of the conveyor belt 6 and can be used as a sample tray. A detection rod 9 is fixedly connected to the rear side of the side plate 2. The detection rod 9 can detect the height of the support component 8. When the height of the support component 8 exceeds the height of the lower surface of the detection rod 9, the sample in the support component 8 can be appropriately reduced, and the overall height of the support component 8 can be further shortened. A housing 10 is fixedly installed in the middle of the base plate 1. Openings 11 are provided on the front, back, and top surfaces of the housing 10. Limiting grooves 12 are provided on the left and right sides of the housing 10. Connecting blocks 13 are slidably installed inside the limiting grooves 12. A top plate 14 is fixedly connected above the connecting blocks 13. The top plate 14 can slide within the limiting grooves 12 via the connecting blocks 13, thereby closing the openings 11 on the top of the housing 10. When the device performs analysis and testing, the top plate 14 can serve as a boundary reference for the testing area. Mixing components 24 are installed on the front and back sides of the top of the housing 10. Adjustment components 23 are provided on the left and right sides of the mixing component 24. An analyzer 15 is installed on the top of the adjustment components 23 and the mixing component 24. A rotating ring 21 is installed inside the analyzer 15. A damping pad 22 is fixedly connected to the inner wall of the rotating ring 21. The adjustment components 23 can precisely adjust the position of the support component 8. The mixing component 24 can mix the sample, thereby modifying the bacterial community structure. The device can switch between modifying the bacterial community structure and precisely adjusting the sample position, or it can perform the modification of the bacterial community structure and the precise adjustment of the sample position simultaneously.

[0039] In this example, the conveyor belt 6 forms a sliding structure with the side plate 2 through the connecting groove 3 and the extension plate 7. The left surface of the extension plate 7 and the right surface of the side plate 2 are in contact with each other. The extension plate 7 is fixedly connected between the side plate 2 and the outer shell 10, which enables the conveyor belt 6 to move straight back and forth, improving the stability of the device during use. The device can adjust the initial position of the sample, which is convenient for subsequent comparative analysis and detection.

[0040] In this example, the support assembly 8 includes a first connecting pipe 801 fitted to the inner wall of the support frame 18, a second connecting pipe 802 slidably mounted inside the first connecting pipe 801, a third connecting pipe 803 slidably mounted inside the second connecting pipe 802, a fourth connecting pipe 804 slidably mounted inside the third connecting pipe 803, and a support plate 805 slidably mounted inside the fourth connecting pipe 804. The first connecting pipe 801, the second connecting pipe 802, the third connecting pipe 803, and the fourth connecting pipe 804... Sealing gaskets 806 are fixedly connected to the inner walls of the device. Sliding grooves 807 are provided around the inner walls of the first connecting pipe 801, the second connecting pipe 802, the third connecting pipe 803, the fourth connecting pipe 804 and the sealing gaskets 806. The first connecting pipe 801, the second connecting pipe 802, the third connecting pipe 803, the fourth connecting pipe 804 and the support plate 805 can be fully extended or fully retracted. The sliding grooves 807 and the sealing gaskets 806 enable the device to maintain a bottom seal when each connecting pipe is extended or retracted, thus preventing sample leakage.

[0041] In this example, the first connecting tube 801, the second connecting tube 802, the third connecting tube 803, the fourth connecting tube 804, and the support plate 805 are nested. The lower surface of the fourth connecting tube 804 is flush with the lower surface of the support plate 805, ensuring the stability of the device when placed as a whole. The nested structure of the connecting tubes allows the device to be used as a test tube after each connecting tube is unfolded, and as a support tray after each connecting tube is retracted, thus improving the versatility of the device.

[0042] In this example, the top plate 14 forms a sliding structure with the outer shell 10 through the limiting groove 12 and the connecting block 13. The inner wall of the limiting groove 12 and the outer wall of the connecting block 13 are in contact with each other. Through the sliding structure on the device, the top plate 14 can move horizontally left and right. The top plate 14 can be used as a reference for analysis and detection, which improves the functionality of the device. The height of the top surface of the inner wall of the outer shell 10 is greater than the height of the bottom surface of the detection rod 9, so that the device can detect the height of the sample before it is sent in, so as to avoid the sample exceeding the height of the top surface of the inner wall of the outer shell 10 and affecting the analysis and detection effect.

[0043] In this example, the support assembly 20 includes a connecting block 2001 fixedly installed on the outside of the second connecting pipe 802. A traction steel rope 2002 is fixedly connected to the top of the connecting block 2001. The top end of the traction steel rope 2002 is guided by a guide wheel 2003 and connected to a winding wheel 2004. Both the guide wheel 2003 and the winding wheel 2004 are rotatably installed inside the first connecting pipe 801. A support plate 2005 is fixedly connected to the outside of the winding wheel 2004. Storage openings for housing the support plate 2005 are provided around the outside of the first connecting pipe 801. The rotation range of the groove 2006 and the support plate 2005 is 0-90°. The lower surface of the support plate 2005 is in contact with the upper surface of the support frame 18. When the second connecting pipe 802 moves downward, the traction steel rope 2002 on the connecting block 2001 pulls the winding wheel 2004 to rotate under the guidance of the guide wheel 2003, so that the winding wheel 2004 drives the support plate 2005 to unfold. After the second connecting pipe 802 on the device unfolds, the support plate 2005 can be automatically unfolded so that it can be supported when used as a test tube.

[0044] In this example, the adjustment component 23 includes a first fixing sleeve 2302 fixedly installed on the left and right sides of the upper surface of the housing 10. A first rotating rod 2301 is rotatably installed inside the first fixing sleeve 2302. A first inner rod 2303 is keyed to the lower part of the first rotating rod 2301. A first sliding sleeve 2304 is rotatably installed on the outer side of the first inner rod 2303. A first moving groove 2305 is formed on the surface of the first fixing sleeve 2302. A first damping block 2306 is fixedly connected to the inner wall of the first moving groove 2305. The bottom of the inner rod 2303 is keyed to a push block 2307. The top of the first fixed sleeve 2302 is connected to the analyzer 15. The device can pull down the first inner rod 2303 so that the bottom of the first inner rod 2303 is keyed to the push block 2307, so that the torque of the first rotating rod 2301 can be transmitted to the push block 2307. When the push block 2307 rotates, it can accurately adjust the position of the sample. The first damping block 2306 makes the first sliding sleeve 2304 stay fixed after moving to the appropriate position.

[0045] In this example, the mixing component 24 includes a second fixing sleeve 2402 fixedly installed on the front and rear sides of the top of the housing 10. A second rotating rod 2401 is rotatably installed inside the second fixing sleeve 2402. A second inner rod 2403 is keyed to the lower part of the second rotating rod 2401. A second sliding sleeve 2404 is rotatably installed on the outer side of the second inner rod 2403. A stirring rod 2407 is installed below the second inner rod 2403. A second moving groove 2405 is formed on the surface of the second fixing sleeve 2402. The inner part of the second moving groove 2405... A second damping block 2406 is fixedly connected to the wall. The top of the second fixed sleeve 2402 is connected to the analyzer 15. The second sliding sleeve 2404 on the pull-down device can drive the stirring rod 2407 to move downward when it moves downward, thereby realizing the function of stirring the sample. When not in use, the stirring rod 2407 and the second sliding sleeve 2404 can be lifted. The second damping block 2406 on the second moving groove 2405 keeps the stirring rod 2407 and the second sliding sleeve 2404 fixed after the position is adjusted.

[0046] In this example, the second rotating rod 2401 and the first rotating rod 2301 form a rotating structure with the second fixed sleeve 2402 and the first fixed sleeve 2302 through the rotating ring 21 and the damping pad 22. The inner wall of the damping pad 22 is provided with longitudinal ridges. The first inner rod 2303 forms a sliding structure with the first rotating rod 2301 and the push block 2307 through the first sliding sleeve 2304. Through the sliding structure on the device, the first inner rod 2303 can move vertically up and down, so that the first inner rod 2303 can be used as a coupling between the first rotating rod 2301 and the push block 2307, so as to switch the pushing position of the sample in the future, thereby improving the adjustability of the device.

[0047] It should be noted that this invention is a microbial detection and analysis instrument with a replaceable slice tray structure. First, as... Figures 1-9As shown, the sliced ​​sample is placed on the support plate 805 inside the support assembly 8, and then the support assembly 8 is placed on the surface of the conveyor belt 6. The connecting groove 3 and the moving plate 4 are used to adjust the initial position of the sample on the conveyor belt 6. The height of the support assembly 8 is detected by the detection rod 9. If the top height of the support assembly 8 is greater than the bottom height of the detection rod 9, the slice inside the support assembly 8 needs to be reduced, and then the support assembly 8 is contracted so that the top height of the support assembly 8 is less than the bottom height of the detection rod 9. During the production of the device, it is necessary to ensure that the bottom height of the detection rod 9 is less than the top height of the inner wall of the outer shell 10, so that the device can ensure that the sample height is not higher than the top height of the inner wall of the outer shell 10 when the sample is fed in, thereby improving the detection effect of the device. The support structure is adjusted using the nested support component 8. When the support component 8 is placed on the support frame 18, it remains fully extended and can be used as a test tube. When the support component 8 is placed on the surface of the conveyor belt 6, it can be retracted and used as a tray. When the support component 8 is used as a test tube, the first connecting pipe 801, the second connecting pipe 802, the third connecting pipe 803, the fourth connecting pipe 804, and the support plate 805 slide through the closed sliding grooves 807 on both the upper and lower sides, thereby expanding or retracting the support component 8. The sealing gasket 806 ensures that the bottom of each connecting pipe remains sealed when expanding or contracting. The support component 20 on the support component 8 can automatically expand, allowing the support component 8 to overlap the surface of the support frame 18. After the support component 8 contracts, the support component 20 can automatically retract. When the support component 8 is expanded, as... Figure 8 As shown, the connecting block 2001 moves downward and pulls the traction steel rope 2002 on the guide wheel 2003, causing the winding wheel 2004 to rotate, thereby unfolding the support plate 2005 from inside the receiving groove 2006. By manually moving the extension plate 7 and the motor 5, the device can manually adjust the position of the sample in the support assembly 8 above the conveyor belt 6, and can also drive the conveyor belt 6 to work via the motor 5, enabling the device to perform comparative testing on samples from different support assemblies 8.

[0048] like Figure 1 , Figure 11 and Figure 12As shown, by rotating the protruding part of the rotating ring 21 on the analyzer 15, the rotating ring 21 drives the first rotating rod 2301 and the second rotating rod 2401 on the adjusting component 23 and the mixing component 24 to rotate via the damping pad 22. This allows the adjusting component 23 and the mixing component 24 to work as a whole or partially. The adjusting component 23 is used to change the position of the supporting component 8. Pulling down the first inner rod 2303 causes the bottom of the first inner rod 2303 to be keyed to the push block 2307. The rotation of the first rotating rod 2301 can drive the push block 2307 to rotate, thereby precisely adjusting the position of the sample. The first damping block 2306 in the first moving groove 2305 allows the first sliding sleeve 2304 to remain fixed after moving to the appropriate position. The mixing component 24 is used to mix the sample. By pulling down the second sliding sleeve 2401... 4. When the second sliding sleeve 2404 moves downward, it can drive the stirring rod 2407 to move downward, thereby changing the stirring depth. When not in use, the stirring rod 2407 and the second sliding sleeve 2404 can be lifted. The second damping block 2406 on the second moving groove 2405 keeps the stirring rod 2407 and the second sliding sleeve 2404 fixed after the position is adjusted. Through the adjustment function on the device, the device can switch between modifying the bacterial community structure and adjusting the sample position, or modifying the bacterial community structure and adjusting the sample position can be carried out simultaneously. After the adjustment and mixing work is completed, the analysis and detection work is carried out by the analyzer 15. The top plate 14 can slide inside the limiting groove 12 through the connecting block 13, thereby adjusting the position of the top plate 14. The top plate 14 can be used as a boundary reference of the detection area.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
