Description

Technical Field

[0001] This invention relates to the field of inoculation tube rack assembly technology, specifically to a test tube rack assembly for batch inoculation in the laboratory. Background Technology

[0002] Microbial inoculation is the process of transferring target microorganisms (bacteria, fungi, etc.) into a fresh, sterile culture medium under aseptic conditions. In particular, photosynthetic microorganisms need to be loaded into test tubes and cultured under light in an incubator before being removed for inoculation testing. Publication No. CN113604338B discloses an inoculation device for mass production of microbial preparations in bioengineering. Its features include: a base plate, a trapezoidal guide groove frame, a shaped rotating frame, a shaped support frame, a reciprocating drive mechanism, a scraping mechanism, a rotary inoculation mechanism, and a switching mechanism. The trapezoidal guide groove frame is fixedly installed on the bottom surface of the base plate, and the trapezoidal guide groove frame has a trapezoidal groove. The shaped rotating frame is welded to the top surface of the base plate, and the shaped support frame is also fixedly installed on the top surface of the base plate. The reciprocating drive mechanism is located above the trapezoidal guide groove frame. The scraping mechanism is fixedly installed on the top surface of the base plate. The rotary inoculation mechanism is located on the scraping mechanism. The switching mechanism is located on the shaped support frame. The reciprocating drive mechanism includes a push rod fixing block, an electric push rod, a first slotted sliding frame, a second slotted sliding frame, a slide rail plate, a return spring, a first reset spring, a limiting round rod, and a compression spring. This device allows the bacterial sample scraped from the scraping ring to fully enter the culture tube, and the scraping ring inoculates the preparation. In practical use, when cultivating and inoculating photosynthetic microorganisms, this device and existing equipment typically involve placing multiple test tubes containing microbial samples in a test tube rack, and then placing the test tube rack in a light incubator for cultivation experiments. During the experiment, it is necessary to turn on the light lamp to irradiate the surface of the test tubes. However, during the irradiation process, the stacking arrangement of the test tubes causes some obstruction on the surface of the test tubes, preventing the microbial samples inside the test tubes from receiving sufficient light, which reduces the actual detection effect of the device. There is room for further improvement in the detection effect of existing equipment on photosynthetic microorganisms. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example Please see Figures 1 to 3 The test tube rack assembly for batch inoculation in the laboratory includes a main body 1, an opening and closing door 10 is rotatably connected to one side of the front end of the main body 1, a control center 11 is fixedly connected to one end surface of the main body 1, a fixing component 2 is fixedly connected to the inner wall of the bottom side of the main body 1, and an illumination lamp is fixedly connected to the rear end of the main body 1. In practical use, when cultivating and inoculating photosynthetic microorganisms, this device and existing equipment usually select to install multiple test tubes containing microbial samples in a test tube rack, and then place the test tube rack in a light incubator for cultivation experiments. During the experiment, the light lamp 30 and the irradiation lamp need to be turned on to irradiate the surface of the test tubes. However, during the irradiation process, due to the stacking arrangement of the test tubes, there is a blocking effect on the surface of the test tubes, and the microbial samples inside the test tubes cannot receive sufficient light, resulting in a reduction in the actual detection effect of the device. There is room for further improvement in the detection effect of existing equipment on photosynthetic microorganisms. This invention discloses a test tube rack assembly for batch inoculation in the laboratory. Multiple test tubes containing photosynthetic microorganism samples are mounted on the test tube base rack 21 via the test tube top rack 27. The control center 11 turns on the light lamp 30 to irradiate the multiple test tubes. During the irradiation process, due to the stacking arrangement of the test tubes, there is some obstruction on the surface of the test tubes, and the microorganism samples inside the test tubes cannot receive sufficient light, resulting in a reduction in the actual detection effect of the device. At this time, the user can turn on and off the fixing component 2 through the control center 11 to ensure that the irradiated area of ​​the test tubes is increased, so that the photosynthetic microorganisms inside the test tubes can receive sufficient light, thereby improving the detection effect of the device and making it easier for users to use. Please see Figures 1 to 4Furthermore, in the above description, an electric turntable is fixedly connected inside the fixed assembly 2. The top output end of the electric turntable passes through the fixed assembly 2 and extends to the top outer side of the fixed assembly 2. A rotating disk 20 is fixedly connected to the extension of the top output end of the electric turntable. A second support 260 is fixedly connected to one side of the top of the rotating disk 20. A side chamber 26 is fixedly connected to the top of the second support 260. A test tube top frame 27 is provided at the other end of the side chamber 26. A first support 210 is fixedly connected to the top surface of the rotating disk 20. A test tube bottom frame 21 is fixedly connected to the top of the first support 210. Two fixing rods 28 are fixedly connected to the other end of the top of the test tube bottom frame 21. The top of the fixing rods 28 is fixedly connected to the bottom side surface of the test tube top clamp. In the above steps, when the illumination lamp 30 and the illumination lamp illuminate the multiple test tubes inside the fixed assembly 2, the light received by the test tubes on the front side is blocked by the test tubes on the rear side, resulting in the test tubes on the front side not receiving sufficient illumination. At this time, the user can use the control center 11 to open the electric turntable. The opening of the electric turntable drives the test tube base frame 21 and the test tube top frame 27 to rotate through the first stand 210 and the second stand 260, respectively. The rotation of the test tube base frame 21 and the test tube top frame 27 drives the multiple test tubes inside to rotate. During the rotation, the illumination area and time of the test tubes on the front and rear sides within the illumination range of the illumination lamp are the same, thereby reducing the situation where the test tubes on the rear side block the test tubes on the front side, resulting in reduced illumination of the test tubes on the front side and reduced detection accuracy, improving the detection accuracy of the device and making it easier for users to use. Please see Figures 5 to 6 Furthermore, as described above, a separation frame 222 is provided at the center of the test tube base 21, and a mounting plate 221 is fixedly connected to the bottom of the separation frame 222. Two second linear drive components 22 are fixedly connected at the top center of the rotating disk 20. The second linear drive components 22 are specifically electric push rods. Output rods 220 are fixedly connected to the top output ends of the two second linear drive components 22. The other ends of the two output rods 220 are fixedly connected to the bottom of the mounting plate 221. Multiple fixing holes 23 are fixedly connected to the top of the separation frame 222 and the test tube base 21. In the above steps, when the rotating disk 20 rotates, the outer test tubes receive light first. The light penetrates the outer test tubes and decreases before shining on the test tube in the center. This results in an uneven amount of light received by the test tube in the center and the test tubes on the outer surfaces. At this time, the user can activate the second linear drive component 22 through the control center 11. The activation of the second linear drive component 22 pushes out the output rod 220 and drives the output rod 220 to move upward. The movement of the output rod 220 drives the separation plate to move upward through the mounting plate 221. The movement of the separation plate drives the test tube in the center to move upward until the test tube on the outer surface can no longer block the test tube in the center. At this time, when the rotating disk 20 rotates and drives the test tubes to rotate, the blocking of the test tube in the center by the test tube on the outer surface is reduced, thereby improving the applicability of the device and making it easier for the user to use. Please see Figures 5 to 6 Further as described above, a first conveying chamber 223 is fixedly connected to the outer surface of multiple fixing holes 23 at the separation frame 222, and the first conveying chamber 223 communicates with the fixing holes 23 at the separation frame 222. A second conveying chamber 231 is fixedly connected to the outer surface of multiple fixing holes 23 at the test tube base frame 21, and the second conveying chamber 231 communicates with the fixing holes 23. A bag 230 is fixedly connected to the inner wall of the fixing hole 23, and the bag 230 is annular. Conveying pipes 232 are fixedly connected to both sides of the other end of the first conveying chamber 223 and to the other end surface of the second conveying chamber 231. A pumping assembly 24 is fixedly connected to the other side of the top of the rotating disk 20. Two connecting pipes 240 are fixedly connected to the output end of one end of the pumping assembly 24. A conveying chamber 241 is fixedly connected to the other end of the two connecting pipes 240. The other end of the conveying chamber 241 is fixedly connected to three conveying pipes 232. In the above steps, when the test tube to be fixed by the fixing component 2 is a small-diameter test tube, it does not contact the limiting plate when passing through the test tube top frame 27 and directly probes into the fixing hole 23 of the test tube bottom frame 21. At this time, the control center 11 turns on the pumping component 24. The pumping component 24 extracts the air inside the regulating chamber 243 through the extraction pipe 242 and delivers it to the first delivery chamber 223 and the second delivery chamber 231 through the connecting pipe 240, the delivery chamber 241 and the delivery pipe 232 respectively. After the first delivery chamber 223 and the second delivery chamber 231 get air, their internal air pressure increases and the bag 230 expands. The bag 230 expands and clamps and fixes the bottom of the small-diameter test tube. When the test tube to be fixed by the fixing component 2 is a large-diameter test tube, it first passes through the limiting plate made of elastic material when passing through the test tube top frame 27. After the limiting plate initially fixes the large-diameter test tube, it is then fixed a second time by the fixing hole 23 and the bag 230 of the test tube bottom frame 21. Thus, the device can fix test tubes of different diameters, improving the applicability of the device. Please see Figures 7 to 8Further as described above, two third linear drive assemblies 261 are fixedly connected inside the side chamber 26. The third linear drive assembly 261 is specifically an electric push rod. The output end of the third linear drive assembly 261 passes through the side chamber 26 and extends to the outer front end of the side chamber 26. A push plate 262 is fixedly connected to the extended part of the output end of the third linear drive assembly 261. Two first meshing plates 263 are fixedly connected to the surface of the other end of the push plate 262. A second meshing wheel 270 is rotatably connected to the end of the test tube top frame 27 near the fixing hole 23. A limit ring 271 is fixedly connected to the inner wall of the meshing plate. Multiple limit plates are fixedly connected to the inner wall of the limit ring 271. The meshing plate extends into the interior of the test tube top frame 27 and meshes with multiple second meshing wheels 270. Due to the different test tube sizes, the obstruction area between the rear test tube and the front test tube varies. When the test tube diameter is small, the volume of the photosynthetic microorganism sample is small, and the decrease in light intensity from the outer test tube to the central test tube is low. The distance between the test tubes is large enough that the light from the lamp can pass through the distance between the rear test tubes. Furthermore, the rotation of the test tube base 21 and test tube top 27 during the above steps ensures that the light can be evenly distributed across the surface of the small-diameter test tubes. When the diameter of the test tube is large, the volume of photosynthetic microorganisms is large, and the light decreases significantly after entering the outer test tubes. This may result in a significant light gradient inside the test tube, meaning that different positions inside the large-diameter test tube receive different amounts of light. Furthermore, the distance between the test tubes decreases, reducing the amount of light that can pass through the gaps between the test tubes. In this case, the light received by the test tubes in the center is blocked by the outer test tubes, resulting in a difference in the amount of light received by the outer test tubes compared to the test tubes in the center. When the test tube diameter is small, it does not contact the limiting plate when passing through the test tube top frame 27, resulting in a lower weight of the test tube. The test tube is mainly fixed by the test tube base frame 21, and the side chamber 26 does not need to be opened, saving energy. When the test tube diameter is large, the test tube is heavier. When passing through the test tube top frame 27, the test tube first passes through a limiting plate made of elastic material. After the limiting plate initially fixes the large-diameter test tube, it is then further fixed by the fixing holes 23 of the test tube base frame 21. This reduces the risk of instability and wobbling of the test tube when it is only fixed by the fixing holes 23 and rotated, especially when the test tube is heavy. Additionally, during the above steps, when the rotating disk 20 rotates and the separating plate moves upward, The control center 11 activates two second linear drive components 22. The activation of the second linear drive components 22 drives two first meshing plates 263 to perform linear reciprocating motion through the push plate 262. The movement of the first meshing plates 263 drives multiple second meshing wheels 270 to perform reciprocating rotation. The rotation of the second meshing wheels 270 drives the large-diameter test tube to rotate through the limiting plate. This allows the large-diameter test tube to not only revolve around the sun but also rotate on its own axis during the process of receiving light. This reduces the problem of light being difficult to penetrate and different positions in the test tube receiving different amounts of light when the volume of photosynthetic microorganisms inside the large-diameter test tube increases. This improves the detection accuracy of the device and makes it easier for users to use. Please see Figures 5 to 6 Further, as described above, an adjustment chamber 243 is fixedly connected to the other end surface of the pumping assembly 24. An extraction pipe 242 is fixedly connected between the adjustment chamber 243 and the pumping assembly 24. Two elastic elements 244, specifically springs, are fixedly connected to the inner wall of the top side of the adjustment chamber 243. A piston plate 245 is fixedly connected to the bottom of the two elastic elements 244. The piston plate 245 is movably connected inside the adjustment chamber 243. A fixing plate 251 is fixedly connected to the other end surface of the piston plate 245. A shield is fixedly connected to the connection between the fixing plate 251 and the adjustment chamber 243. The fixing plate 251 penetrates the adjustment chamber 243 and extends into the interior of the adjustment chamber 243. An adjustment plate 250 is fixedly connected to the extended portion of the fixing plate 251. The adjustment plate 250 is slidably connected inside the adjustment trigger 25. A connecting frame 252 is fixedly connected to the bottom of the adjustment trigger 25. The bottom of the connecting frame 252 is fixedly connected to the top of the rotating disk 20. In the above steps, the expansion amount of the capsule 230 varies depending on the diameter of the test tubes. The pumping assembly 24 also draws different amounts of air from the regulating chamber 243 via the extraction tube 242. Initially, the capsule 230 does not expand, and the air pressure inside the regulating chamber 243 reaches its maximum value. At this time, the regulating trigger 25 is at its maximum setting, and the distance between the light lamp 30 and the surface of the photosynthetic microorganism sample liquid inside the test tube on the test tube top rack 27 is the closest, resulting in the lowest light attenuation. The light emitted by the light lamp 30 to the test tube reaches its maximum value. The fact that the capsule 230 does not expand means that a large-diameter test tube is loaded in the fixing hole 23. The volume of photosynthetic microorganism sample loaded in the large-diameter test tube increases, meaning there is enough photosynthetic microorganism sample inside the large-diameter test tube to receive light and achieve light saturation. As the capsule 230 expands, the air pressure inside the fixing hole... When the diameter of the test tube fixed at position 23 is reduced, the air pressure inside the regulating chamber 243 decreases, the piston plate 245 moves downward and drives the regulating plate 250 to move down at the regulating trigger 25 via the fixed plate 251. At this time, the regulating trigger 25 moves down, causing the first linear drive component 120 to drive the light component 3 to move upward. The light lamp 30 moves upward, increasing the distance between the light lamp 30 and the liquid surface inside the test tube, and increasing the light attenuation. The volume of photosynthetic microorganisms loaded inside the small-diameter test tube is relatively reduced. At this time, the attenuated light is more conducive to the small-volume photosynthetic microorganisms achieving light saturation. After the above steps are combined, the device can adjust the expansion degree of the bag 230 and the distance of the light lamp 30 according to the different diameter test tubes, thereby adjusting the light intensity according to the different volumes of photosynthetic microorganism samples that can be loaded inside the test tubes of different diameters. In the above steps, when the illuminating lamp 30 moves down and the illumination intensity increases, the beam angle decreases, that is, the illumination area decreases; when the illuminating lamp 30 moves up and the illumination intensity decreases, the beam angle increases, that is, the illumination area increases. For large-diameter test tubes, the reduced illumination area causes illumination dead angles on the surface of large-diameter test tubes, while for small-diameter test tubes, the increased illumination area means that part of the illumination irradiates outside the test tube area, resulting in waste. In the present application, the focal length of the convex lens 310 is set as f, and the distance between the illuminating lamp 30 and the convex lens 310 is set as u. In the initial condition of the above steps, the distance between the illuminating lamp 30 and the test tube is the shortest, the illumination intensity is the maximum, and the distance between the convex lens 310 and the illuminating lamp 30 is the shortest. At this time, u<f, the illuminating lamp 30 is within the focal point of the convex lens 310, the lens forms a virtual image, the light diverges, and the beam angle becomes larger, thereby increasing the illumination area on the surface of the large-diameter test tube. When the illuminating lamp 30 gradually moves away from the test tube, the illumination intensity decreases. While the illumination assembly 3 moves, the third engaging plate 34 moves upward on the outer surface of the first engaging wheel 130 and drives the first engaging wheel 130 to rotate. The rotation of the first engaging wheel 130 causes the second engaging plate 33 to move downward inside the illumination assembly 3.
