Description

Technical Field

[0001] This application relates to the field of testing auxiliary equipment technology, and in particular to a sample isothermal oscillation device. Background Technology

[0002] A thermostatic shaker is a laboratory device that combines a thermostatic water bath with shaking functionality. It provides a stable temperature environment for samples to be tested in the laboratory, meeting the temperature requirements of different experimental materials. Furthermore, thermostatic shakers can be used to study the physical, chemical, and biological properties of substances. By controlling parameters such as temperature and shaking frequency, studies can be conducted on material structure, composition, and chemical reactions. For example, in food quality inspection, thermostatic shaking can accelerate the metabolic processes of microorganisms in food, rapidly assessing spoilage risks. When testing petrochemical products, specific temperatures and shaking frequencies can be set to simulate the actual usage conditions of the products to test their performance. When testing biological products, the shaking function of this device ensures uniform mixing of reagents, guaranteeing accurate test results.

[0003] Current isothermal shakers can be broadly categorized into two types based on their method of securing sample containers: spring-rod type and beaker rack type. The spring-rod type features multiple crisscrossing spring ropes fixed to the shaker frame inside the shaker. When placing the sample, the container containing the sample is inserted into the holes created by the crisscrossing of the spring ropes. The sample-filled container stretches the spring ropes, causing them to deform and generate elasticity, which temporarily secures the sample-filled container. This type of isothermal shaker is suitable for small-capacity sample containers (such as test tubes smaller than 100 ml) and for the simultaneous oscillation of multiple batches of samples. For large-capacity containers containing samples, such as 200ml beakers, when fixed by inserting them into the holes between the spring ropes, the inertia generated by the continuous shaking of the samples inside the beakers due to the large amount of sample inside, makes it difficult for the shaking of the samples to be synchronized with that of the beakers. In this case, the clamping stability of the spring ropes for large-volume beakers is obviously insufficient. This is where a beaker rack-type thermostatic shaker is needed. The beaker rack-type thermostatic shaker has a special beaker fixing bracket or tray fixedly installed on the shaker. When in use, large-volume containers can be directly clamped in the designated area on the beaker rack to ensure good stability of large-volume containers containing a lot of samples during the shaking experiment.

[0004] In reality, many laboratories frequently handle samples of various sizes beyond a single category. For instance, some laboratories may conduct both food biological testing and water / soil testing. Food biological testing often involves microbial culture and DNA / RNA hybridization experiments, which frequently require processing multiple small-volume test tubes using a constant-temperature shaker. In such cases, a spring-rod type constant-temperature shaker is more suitable. However, when conducting water or soil testing, containers larger than 200ml are often used (for example, in water testing, to ensure sufficient contact between the water sample and microorganisms and to avoid data deviation due to insufficient sample volume in small containers, a 500ml water sample is placed in a beaker, diluted with diluent and microbial culture, and placed in a beaker-type water bath constant-temperature shaker, set to constant temperature and continuous shaking for 5 days). In this case, to ensure the stability of large-volume containers during the shaking process, a beaker rack type constant-temperature shaker is required. This leads to the need for laboratories to purchase both a spring-rope type thermostatic shaker and a beaker rack type thermostatic shaker spring rope to meet their different needs in various scenarios. This obviously not only increases the space occupied by the equipment in the laboratory, but also increases the laboratory's equipment purchase costs. Utility Model Content

[0005] This application provides a sample isothermal oscillation device, which can effectively solve the problems existing in the use of the existing isothermal oscillation equipment in the background art.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A sample isothermal oscillation device includes an oscillator, and a shaking table is provided inside the oscillator. The shaking table is provided with a first clamping area and a second clamping area from bottom to top along the vertical direction.

[0008] The first clamping area is used to clamp a first container or a second container, and the second clamping area is used to clamp a second container, wherein the volume of the second container is larger than the volume of the first container;

[0009] The second clamping area includes two mounting baffles fixedly installed on a pair of sides of the top of the shaker frame. A support plate is movably connected to the adjacent sides of the two mounting baffles. Each support plate is provided with a plurality of clamping modules for fixing the second container.

[0010] Furthermore, the clamping module includes a clearance through hole that passes through the support plate along its thickness direction. An arc-shaped clamping plate is provided on one opposite side of the upper end of the clearance through hole along the line connecting the two mounting baffles. Two strip-shaped sliders are fixedly installed on the opposite sides of the two arc-shaped clamping plates. A fixing sleeve is fitted on each strip-shaped slider and the two are slidably connected. The lower side of the fixing sleeve is fixedly installed on the support plate. An adjusting bolt is inserted through the same end on one side of the two arc-shaped clamping plates. A nut is threaded onto the adjusting bolt.

[0011] Furthermore, the arc-shaped clamp at the end of the strip slider away from its connected position has an upwardly extending protrusion.

[0012] Furthermore, each support plate has two clamping modules, and the two clamping modules are symmetrically arranged on the support plate along the length direction of the mounting baffle; the support plate is provided with a dividing slit, which divides the support plate into two independent sub-plates, and the dividing slit is collinear with the line connecting the center points of the two clearance through holes in the two clamping modules on the support plate; the two ends of the two sub-plates are hinged together by hinges along their length direction.

[0013] Furthermore, an integrally formed mounting base is provided on the inner side of the lower end of the mounting baffle, and a groove matching the shape of the mounting base is provided on the end of the sub-plate on the adjacent side of the mounting baffle. The mounting base is inserted into the groove and the two are movably connected by a hinge shaft.

[0014] Furthermore, each of the two sub-plates that make up the same support plate has a first positioning hole at its far ends, and the mounting baffle has a second positioning hole. The two first positioning holes and the second positioning hole are located on the same plane that is perpendicular to the horizontal plane. The distance between the second positioning hole and the lower end of the mounting baffle is such that when the two sub-plates are folded upwards, they can form a through hole with the two first positioning holes.

[0015] Furthermore, a fastening nut is welded to the opposite side of the second positioning hole on each of the two mounting baffles.

[0016] Furthermore, the first positioning holes on the two sub-plates on the side of the two support plates that are close to each other are provided with internal threads. A connecting plate is placed on the two first positioning holes with internal threads. Two round-head screws are inserted into the connecting plate, and the two round-head screws are threadedly connected to the two first positioning holes with internal threads.

[0017] Furthermore, the first clamping area includes two layers of spaced-apart frames, each layer of frames being fixedly connected to the shaking table, and each layer of frames having multiple intersecting spring ropes fixedly installed inside.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The shaker in this application has a second clamping area above the internal shaking bed. This area is mainly used to clamp a second container with a larger overall volume than the first container. The second container can be a large-capacity beaker commonly used in laboratory sample testing, while the first container can be a small-capacity test tube used in laboratory sample testing. A support plate is movably connected to each of the two mounting baffles in the second clamping area. When the testing personnel need to place the large-capacity beaker in the shaker for isothermal oscillation, to ensure the stability of the oscillation process, the two support plates can be adjusted to a horizontal position. After placing the large-capacity beaker in the first clamping area, it can be further fixed by the clamping module on the support plate in the second clamping area. This allows for the use of two fixing methods in the first and second clamping areas to secure the large-capacity beaker, meeting the high stability requirements during isothermal oscillation. When testing personnel need to perform batch isothermal oscillation on small-capacity test tubes, the position of the support plate can be adjusted to fold upwards, thereby exposing the second clamping area located below the first clamping area. At this point, the testing personnel can fix the small-capacity test tubes one by one, referring to the operation method of the spring rope type in the prior art. In this way, when using the oscillation device of this application, the testing personnel can flexibly choose to use the first clamping area and the second clamping area, or simply use the second clamping area, depending on the sample containers contained and the characteristics of the testing process. Compared with the prior art, this not only saves on equipment purchase costs but also reduces the equipment's space occupancy in the laboratory. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0027] like Figures 1-4 As shown, a sample isothermal oscillation device disclosed in this application includes an oscillator 1. The oscillator 1 is provided with a shaker 2 for placing a sample container. The shaker 2 is provided with a first clamping area 3 and a second clamping area 4 arranged sequentially from bottom to top along the vertical direction.

[0028] The first clamping area 3 is used to clamp the first container, and the second clamping area 4 is used to clamp the second container with a volume larger than the first container;

[0029] The second clamping area 4 includes two mounting baffles 41 fixedly installed on a pair of sides of the top of the shaker 2 frame. A support plate 42 is movably connected to the adjacent sides of the two mounting baffles 41. Each support plate 42 is provided with a plurality of clamping modules 43 for fixing the second container.

[0030] In the above embodiments, the first container in this application is a small-capacity container commonly used in laboratory testing. For ease of understanding, the first container will be referred to as a small-capacity test tube (with a volume of no more than 100 ml) containing the sample in the following content. Correspondingly, the second container, which is larger in volume than the first container, is a large-capacity container that may be commonly used in laboratory testing. For ease of understanding, the second container will be referred to as a large-capacity beaker (with a volume of no less than 200 ml) containing the sample in the following content.

[0031] The second clamping area 4 of this application is located above the first clamping area 3 on the shaker 2 inside the oscillator 1. The second clamping area 4 is provided with a support plate 42 for multiple clamping modules 43 and a mounting baffle 41 on the top of the shaker 2. When the tester is testing food biological samples, it is necessary to perform constant temperature oscillation on multiple small-capacity test tubes. At this time, it may be necessary to place multiple batches of small-capacity test tubes on the shaker 2 for synchronous processing. When using small-capacity test tubes, the elasticity of the spring rope 32 is sufficient to fix them well. At this time, the tester is more concerned about the convenience of operation. Therefore, the tester can rotate the two support plates 42 upwards to expose the second clamping area 4 located below the first clamping area 3. Referring to the operation method of the constant temperature oscillation equipment with spring rope in the prior art, the small-capacity test tubes can be quickly fixed one by one in the second clamping area 4. When testing water or soil samples, if a small number of large-capacity beakers are needed, the testers can lower the two support plates 42, place the large-capacity beakers in the first clamping area 3, and then further fix the large-capacity beakers in place using the clamping modules 43 on the support plates 42 in the second clamping area 4. In this way, the large-capacity beakers can be fixed using two fixing methods in the first clamping area 3 and the second clamping area 4 to meet the high stability requirements during the isothermal oscillation process. Therefore, when using the constant temperature oscillation device of this application, the testing personnel can flexibly choose whether to use the first clamping area 3 and the second clamping area 4, or only the second clamping area 4, depending on the sample container it contains and the characteristics of its testing process. Unlike the prior art, if the sample containers used for laboratory testing involve both small-capacity containers such as test tubes and large-capacity containers such as beakers, it is necessary to purchase both elastic rope-type constant temperature oscillation devices and beaker-type constant temperature oscillation devices. Therefore, compared with the prior art, the constant temperature oscillation device of this application is not only more flexible and convenient to use, but also saves equipment purchase costs and reduces the equipment's occupation of laboratory space.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping module 43 includes a clearance through hole 431 that passes through the support plate 42 along its thickness direction. An arc-shaped clamping plate 432 is provided on one opposite side of the upper end of the clearance through hole 431 along the line connecting the two mounting baffles 41. Two strip sliders 433 are fixedly installed on the opposite sides of the two arc-shaped clamping plates 432. A fixing sleeve 434 is fitted on each of the strip sliders 433 and the two are slidably connected. The lower side of the fixing sleeve 434 is fixedly installed on the support plate 42. An adjusting bolt is inserted through the same end on one side of the two arc-shaped clamping plates 432. A nut is threaded onto the bolt body of the adjusting bolt.

[0033] In the above embodiments, the size of the clearance through hole 431 provided on the support plate 42 is larger than the maximum diameter of the large-capacity beaker commonly used in the testing room. For example, the diameter of a common 200 ml beaker is 64 mm and the mouth diameter is 73 mm. If the large-capacity beaker commonly used in the laboratory is of this size, the diameter of the clearance through hole 431 can be set to at least 80 mm. This ensures that the large-capacity beaker containing the sample can pass smoothly through the clearance through hole 431. An arc-shaped clamping plate 432 is provided on one opposite side of the clearance through hole 431 along the line connecting the center points of the two mounting baffles 41. The arc-shaped clamping plates 432 are slidably connected by the strip slider 433 on the back and the fixed sleeve 434 at the corresponding position on the support plate 42. An adjusting bolt is inserted between one end of the two arc-shaped clamping plates 432 on the same side. After the testing personnel place the large-capacity beaker on the shaker 2 at the corresponding position of one of the clearance through holes 431, the adjusting bolt can be used to adjust the size of the beaker. Tighten the nuts to drive the two arc-shaped clamps 432 to clamp the large-capacity beaker. Alternatively, the inspector can manually hold the two arc-shaped clamps 432 close to each other under the guidance of the fixed sleeve 434 and the strip slider 433 until the two arc-shaped clamps 432 fix the large-capacity beaker. Then, tighten the nuts on the adjusting bolts to keep the two arc-shaped clamps 432 in a fixed state. This ensures that the large-capacity beaker remains stable during the constant temperature oscillation process.

[0034] Furthermore, such as Figure 3 As shown, the strip slider 433 has an upwardly extending protrusion 5 at one end of the arc-shaped clamp 432 away from its connected position.

[0035] In the above embodiments, the protrusion 5 provided on the strip slider 433 can effectively prevent the strip slider 433 from accidentally coming off the fixing sleeve 434 when it moves with the arc-shaped clamp 432.

[0036] Furthermore, such as Figures 2-4 As shown, each support plate 42 has two clamping modules 43, and the two clamping modules 43 are symmetrically arranged on the support plate 42 along the length direction of the mounting baffle 41; the support plate 42 is provided with a dividing slit 6, which divides the support plate 42 into two independent sub-plates 421, and the dividing slit 6 is collinear with the line connecting the center points of the two clearance through holes 431 in the two clamping modules 43 on the support plate 42; the two ends of the two sub-plates 421 in the length direction are hinged together by a hinge 7.

[0037] In the above embodiments, the two clamping modules 43 on the support plate 42 of this application are symmetrically arranged along the length direction of the mounting baffle 41, and a dividing slit 6 is provided along the direction of the line connecting the center points of the two clamping modules 43. The dividing slit 6 cuts the support plate 42 into two independent sub-plates 421. The two sub-plates 421 are hinged together by a hinge 7. In this way, when the testing personnel need to store the support plate 42 to use the first clamping area 3 on the shaker 2, they can fold the support plate 42 upward to a vertical state, and then further fold one of the sub-plates 421 away from the top of the shaker 2 downward around the hinge axis of the hinge 7. This can effectively reduce the occupancy rate of the upper space of the shaker 2 inside the oscillator 1 after the support plate 42 is stored.

[0038] Furthermore, such as Figure 3 and Figure 4 As shown, an integrally formed mounting base 8 is formed on the inner side of the lower end of the mounting baffle 41. The end of the sub-plate 421 on the adjacent side of the mounting baffle 41 is provided with a groove 9 that matches the shape of the mounting base 8. The mounting base 8 is inserted into the groove 9 and the two are movably connected by a hinge shaft.

[0039] In the above embodiments, the mounting base 8 on the inner side of the lower end of the mounting baffle 41 is inserted into the groove 9 at the end of the corresponding side sub-plate 421, and the two are movably connected by a hinge shaft. This not only allows the sub-plate 421 to swing around the hinge shaft as needed to adjust its position, but also allows the upper surface of the sub-plate 421 to achieve a close fit with the mounting baffle 41 when the sub-plate 421 is rotated upward to a state perpendicular to the horizontal plane. This effectively improves the overall compactness of the device when the support is in the folded state. To avoid the strip slider 433 on the arc-shaped clamp 432 from obstructing the close fit between the support plate 42 and the mounting baffle 41, a corresponding recessed groove can be opened on the mounting baffle 41 at the position corresponding to the strip slider 433 on the corresponding side sub-plate 421, so that when the sub-plate 421 is folded up, the strip slider 433 on its arc-shaped clamp 432 can be temporarily stored in the recessed groove on the mounting baffle 41.

[0040] Furthermore, such as Figure 3 and Figure 4 As shown, each of the two sub-plates 421 that make up the same support plate 42 has a first positioning hole 10 at its far ends. The mounting baffle 41 has a second positioning hole 11. The two first positioning holes 10 and the second positioning hole 11 are located on the same plane that is perpendicular to the horizontal plane. The distance between the second positioning hole 11 and the lower end of the mounting baffle 41 is such that when the two sub-plates 421 are folded upwards, they can form a through hole with the two first positioning holes 10.

[0041] In the above embodiments, each of the sub-plates 421 that make up the same support plate 42 in this application has a first positioning hole 10 at its far ends. After the two sub-plates 421 are folded up in the upper direction of the shaker 2, the first positioning holes 10 on the two sub-plates 421 are exactly connected to the second positioning holes 11 on the corresponding side mounting baffle 41 to form a through hole. At this time, the tester only needs to pass a bolt through the through hole and tighten a nut on the bolt to achieve the effect of stably connecting the support plate 42 as a whole and the corresponding side mounting baffle 41 together, so as to prevent the support plate 42 from interfering with the sample container in the first clamping area 3 when the shaker 2 is oscillating.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, a fastening nut 12 is welded to the opposite side of the second positioning hole 11 on each of the two mounting baffles 41.

[0043] In the above embodiments, a fastening nut 12 is welded to the mutually distant sides of the second positioning holes 11 on the two mounting baffles 41. In this way, after the inspection personnel use bolts and nuts to fix the support plate 42 and the mounting baffle 41, they can avoid the trouble of manually controlling the nuts in the narrow space outside the mounting baffle 41.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, the first positioning holes 10 on the two sub-plates 421 on the side of the two support plates 42 that are close to each other are provided with internal threads. A connecting plate 13 is placed on the two first positioning holes 10 with internal threads, and two round-headed screws are inserted into the connecting plate 13.

[0045] In the above embodiments, the length of the support plate 42 along the length direction of the mounting baffle 41 is such that when it rotates to a horizontal state around the hinge axis movably connected to the mounting baffle 41, both ends of the support plate 42 along the length direction of the mounting baffle 41 can rest on the top of the shaker 2 frame. This helps the testing personnel to quickly adjust the support plate 42 to a horizontal state above the shaker 2. To ensure that the horizontal support plate 42 does not wobble during use, the first positioning hole 10 on the two sub-plates 421 on the adjacent sides of the two support plates 42 is set as a hole with internal thread, so that the testing personnel can place the connecting plate 13 inside the internal thread. Above the two first positioning holes 10 of the textured structure, and align the holes on the connecting plate 13 for inserting round head screws 14 with the two first positioning holes 10 respectively. Finally, screw the two round head screws 14 into the two first positioning holes 10 with internal threads. At this time, the two round head screws 14 can fix the sub-plates 421 of the two support plates 42 close to each other through the connecting plate 13. With the two mounting baffles 41 restricting the position of the other two sub-plates 421, the two support plates 42 can be fixed above the shaker 2 to ensure the stability of the large-capacity container during the constant temperature oscillation process.

[0046] Furthermore, such as Figures 2-4 As shown, the first clamping area 3 includes two layers of partition frames 31 with intervals between them. The partition frames 31 are fixedly connected to the shaker 2. Multiple spring ropes 32 that are interwoven are fixed inside each partition frame 31.

[0047] In the above embodiments, the first clamping area 3 of this application includes two layers of partition frames 31, and each layer of frame is provided with multiple intersecting spring ropes 32. When small-capacity test tubes, small-capacity wide-mouth bottles, or other containers are inserted into the intersection area of ​​the spring ropes 32 in the two layers of partition frames 31, two fixing points can be formed on the small-capacity container through the spring ropes 32 in different partition frames 31. This ensures that even when fixing small-capacity containers, the risk of shaking during oscillation can be effectively reduced. Furthermore, the first clamping area 3 of this application is located below the second clamping area 4. When a large-capacity container needs to be oscillated, the lower half of the large-capacity container can be sequentially inserted into the intersection area of ​​the spring ropes 32 in the two layers of partition frames 31, while the upper end of the large-capacity container is fixed by the clamping module 43 of the second clamping area 4. This further improves the stability of the large-capacity container during oscillation.

[0048] The implementation principle of this embodiment is as follows: When the tester needs to place a large-capacity beaker containing a large number of samples in the shaker 1 for constant temperature oscillation, the tester needs to first determine the state of the second clamping area 4 on the shaker 2 inside the shaker 1. If both support plates 42 in the second clamping area 4 are in a horizontally connected state, the tester can directly insert the large-capacity beaker through the clearance through hole 431 on one of the support plates 42, ensuring that its lower end passes through the first clamping area 3 in sequence. Then, the adjusting bolt can be inserted into the same end of the two arc-shaped clamping plates 432 at the corresponding position, and then the nut is installed on the adjusting bolt. After the large-capacity beaker is fixed by the two arc-shaped clamping plates 432 by tightening the nut, the protective cover of the shaker 1 can be closed and the corresponding constant temperature oscillation operation can be started. After the constant temperature oscillation operation is completed, the tester reopens the protective cover of the shaker 1, removes the adjusting bolt and nut on the arc-shaped clamping plate 432 that fixes the large-capacity beaker, and removes the large-capacity beaker to proceed to the next experiment. Subsequently, if the testing personnel need to perform constant temperature oscillation on multiple small-capacity test tubes containing a small amount of samples, in order to improve the convenience of operation, the testing personnel can first unscrew the round-head screws 14 on the connecting plate 13 used for connection on the side sub-plates 421 of the two support plates 42, then remove the connecting plate 13, fold up the sub-plates 421 of the two support plates 42, then fold up the sub-plates 421 on the side closer to the mounting baffle 41, and finally insert a bolt into the through hole formed by the first positioning hole 10 on the two sub-plates 421 and the second positioning hole 11 on the mounting baffle 41, and tighten the bolt to adjust its insertion depth into the fastening nut 12 on the outside of the mounting baffle 41 until the two sub-plates 421 and the corresponding side mounting baffle 41 are firmly fixed. At this point, the second clamping area 4 can be stored above the shaker 2, and the first clamping area 3 located below the second clamping area 4 will be exposed. The tester can refer to the existing spring rope constant temperature oscillation equipment and insert multiple small-capacity test tubes one by one into the cross area formed by the spring ropes 32 at different positions. The spring ropes 32 will use the elasticity generated by their deformation to quickly fix the small-capacity test tubes. Finally, close the protective cover of the shaker 1 and start the corresponding constant temperature oscillation operation. After the constant temperature oscillation operation is completed, the tester can reopen the protective cover of the shaker 1 and take out multiple small-capacity test tubes in turn for the next experiment.

[0049] If the two support plates 42 of the second clamping area 4 are in the retracted state in the initial state, the inspector can first remove the bolts used to fix the two support plates 42, then unfold the sub-plates 421 that make up the two support plates 42 on the top of the shaker 2 and adjust them to a horizontal state. Then, use the round head screws 14 and the connecting plate 13 to fix the sub-plates 421 on the side of the two support plates 42 that are close to each other. In this way, the second clamping area 4 can be in the unfolded state above the first clamping area 3. The operation method for installing the large capacity beaker is the same as above, and will not be described in detail here.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
