[0002] Test tube racks are the most basic laboratory equipment in chemistry labs, used to place (and sometimes observe) test tubes for experimental observation and drying. The use of test tube racks helps laboratory staff avoid direct contact with test tubes, thus ensuring the safety of experimental operations. Because some chemical reagents are highly hazardous, failure to take appropriate safety measures could lead to experimental accidents. Using test tube racks effectively avoids the danger of direct contact between laboratory personnel and test tubes.
[0003] Common test tube racks include wooden test tube racks, stainless steel test tube racks, plastic test tube racks, etc.; these test tube racks all include a bracket and a support plate. The support plate has multiple sets of holes with a diameter slightly larger than the diameter of the test tube. When in use, the test tube is inserted into the hole to fix the test tube.
[0004] Problems with existing technology: Since common test tube racks do not have a guiding structure, users can insert test tubes randomly. Although this is convenient, in some more complex usage scenarios, random insertion of test tubes may cause confusion for the experimenter, and it is very easy to pick up test tubes that are not the required ones. In experiments with certain risks, this may lead to dangerous situations.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Please see Figures 1-6 As an embodiment of this utility model, the interlocked opening multifunctional test tube rack includes symmetrically arranged brackets 1; the two brackets 1 are connected by a first shelf 2 and a second shelf 3.
[0028] The first shelf 2 has multiple sets of first apertures 201; the second shelf 3 has a second aperture 301 that matches the first apertures 201.
[0029] Each of the first apertures 201 is provided with a closing structure, the closing structure including two symmetrically arranged opening and closing clamps 4; the two opening and closing clamps 4 can move away from or close to each other;
[0030] The first shelf 2 is provided with multiple sets of locking structures that cooperate with the closing structure; the locking structure can restrict the movement of the opening and closing clamp 4, and can release the locking state of the locking structure after two adjacent opening and closing clamps 4 move away from each other.
[0031] In this embodiment, the first aperture 201 and the second aperture 301 cooperate to form a test tube rack. When in use, the test tubes are inserted into the first aperture 201 and the second aperture 301 to keep the test tubes vertical and prevent the test tubes from tilting and causing sample leakage. Multiple test tube racks are named "first test tube rack", "second test tube rack", "third test tube rack" and so on along the length of the first shelf 2.
[0032] In the initial state, the locking structure and the closing structure work together to ensure that all test tube racks except the "first test tube rack" are in a closed state (the locking structure restricts the opening and closing of the clamp 4).
[0033] When a test tube is inserted into the "first test tube rack", the test tube will squeeze the opening and closing clamp 4, causing the opening and closing clamp 4 to move away from each other. During the operation of the closing structure on the "first test tube rack", the locking state of the locking structure on the "second test tube rack" will be released, allowing the closing structure on the "second test tube rack" to operate. At this time, the second test tube can be inserted into the "second test tube rack". During the operation of the closing structure on the "second test tube rack", the locking state of the locking structure on the "third test tube rack" will be released, allowing the third test tube to be inserted into the "third test tube rack".
[0034] Therefore, the process of inserting multiple test tubes into the test tube rack is as follows: after the first test tube is inserted into the "first test tube rack", the second test tube can be inserted into the "second test tube rack"; after the second test tube is inserted into the "second test tube rack", the third test tube can be inserted into the "third test tube rack".
[0035] By combining locking and closing mechanisms, the test tubes can be placed in an orderly manner, which can improve the accuracy of experiments and prevent the incorrect use of samples or reagents due to disordered or chaotic placement of test tubes, thereby improving the accuracy of experiments or tests.
[0036] As a further embodiment of this utility model, the opening and closing clamp 4 is slidably fitted with the first shelf 2; the closing structure also includes a wedge 5 and a sliding rod 7 slidably mounted on the first shelf 2; the wedge 5 abuts against one of the opening and closing clamps 4; the sliding rod 7 is provided with a clearance groove 701, and the other opening and closing clamp 4 is slidably engaged with the clearance groove 701; the first shelf 2 is provided with a first spring 6 and a second spring 8; the two ends of the first spring 6 abut against the wedge 5 and the first shelf 2 respectively; the two ends of the second spring 8 abut against the sliding rod 7 and the first shelf 2 respectively.
[0037] In this embodiment, the sides of the opening and closing clamps 4 that are far apart from each other are inclined; the side of the relief groove 701 that abuts against the opening and closing clamps 4 is a slope; and the side of the wedge block 5 that abuts against the opening and closing clamps 4 is an inclined surface.
[0038] Initially, the two opening and closing clamps 4 abut against each other, so that the conductive area of the first aperture 201 is smaller than the cross-sectional area of the test tube, thus keeping the first aperture 201 in a closed state. The cooperation between the locking and closing structures ensures orderly placement of the test tubes, improving experimental accuracy and preventing incorrect use of samples or reagents due to disordered or chaotic placement, thereby enhancing the accuracy of experiments or tests.
[0039] During the insertion of the test tube into the first aperture 201, the bottom of the test tube will come into contact with the opening and closing clamp 4; then, the test tube will squeeze the opening and closing clamp 4 to make the opening and closing clamp 4 move away from each other, thereby increasing the conduction area of the first aperture 201.
[0040] During the process of the opening and closing clamps 4 moving away from each other, one opening and closing clamp 4 cooperates with the wedge block 5. The inclined surface of the opening and closing clamp 4 interacts with the inclined surface of the wedge block 5 to drive the wedge block 5 to slide and compress the first spring 6. Meanwhile, the other opening and closing clamp 4 cooperates with the relief groove 701. The inclined surface of the opening and closing clamp 4 interacts with the slope of the relief groove 701 to drive the slide rod 7 to slide and compress the second spring 8.
[0041] When the test tube is removed from the test tube rack, the elastic force of the first spring 6 and the second spring 8 will cause the wedge block 5 and the slide rod 7 to reset, thereby causing the two opening and closing clamps 4 to move closer to each other and re-close the first aperture 201.
[0042] As a further embodiment of this utility model, the locking structure includes an unlocking groove 702 formed on the slide bar 7; the unlocking groove 702 cooperates with an opening and closing clamp 4 on the adjacent closing structure.
[0043] In this embodiment, taking the "second test tube rack" as an example, in the initial state, one of the opening and closing clamps 4 on the "second test tube rack" abuts against the slide bar 7 on the "first test tube rack", so that the two opening and closing clamps 4 cannot move away from each other, thereby restricting the insertion of test tubes, and at this time the unlocking groove 702 is misaligned with the opening and closing clamps 4.
[0044] When a test tube is inserted into the "first test tube rack", the slide bar 7 will slide, thereby causing the unlocking groove 702 to move. During the sliding process, the contact area between the slide bar 7 and the opening and closing clamp 4 on the "second test tube rack" will gradually decrease. When the slide bar 7 stops sliding, the opening and closing clamp 4 will disengage from the slide bar 7. At this time, when the test tube is inserted into the "second test tube rack", the opening and closing clamp 4 will slide into the unlocking groove 702.
[0045] By combining locking and closing mechanisms, the test tubes can be placed in an orderly manner, which can improve the accuracy of experiments and prevent the incorrect use of samples or reagents due to disordered or chaotic placement of test tubes, thereby improving the accuracy of experiments or tests.
[0046] As a further embodiment of this utility model, a sleeve 9 that mates with the second aperture 301 is fixedly installed on the second shelf 3, and a top post 10 is slidably fitted inside the sleeve 9; a mounting bracket 14 is fixedly installed on the second shelf 3; a pressing block 13 is slidably fitted on the mounting bracket 14; a slider 11 is slidably installed on the mounting bracket 14; one end of the slider 11 abuts against the pressing block 13, and the other end abuts against the top post 10; a return spring 12 is also provided on the mounting bracket 14; both ends of the return spring 12 abut against the slider 11 and the mounting bracket 14, respectively.
[0047] In this embodiment, after the test tube is placed in the test tube rack, the test tube will enter the sleeve 9, and the bottom of the test tube will abut against the top post 10. Both ends of the slider 11 are set as sloping surfaces.
[0048] The test tube is retrieved by pressing the pressing block 13. During the pressing process, the pressing block 13 drives the slider 11 towards the sleeve 9 via the inclined surface of the slider 11, compressing the return spring 12. As the slider 11 moves, its other inclined surface presses against the top post 10, causing the top post 10 to slide along the length of the sleeve 9, thereby driving the test tube to move synchronously. As the test tube moves, the length of the exposed test tube rack gradually increases, making it easier for the user to retrieve the tube and effectively preventing contamination of the test tube opening, thus improving the accuracy of the experiment.
[0049] As a further improvement of this utility model, multiple sets of test tube supports 1402 are fixedly installed on the mounting bracket 14.
[0050] In this embodiment, during the storage or preparation stage, the test tubes can be inverted on the support column 1402 to prevent them from being contaminated by the outside world and to make it convenient for users to take them out and use them.
[0051] As a further embodiment of this utility model, multiple sets of baffles 1401 are fixedly installed on the mounting bracket 14; the baffles 1401 abut against the slider 11.
[0052] In this embodiment, the baffle 1401 is provided to prevent the slider 11 from shifting position during movement, thereby improving the stability of the test tube rack.
[0053] As a further improvement of this utility model, the bracket 1 has a slot 101 that can be opened and closed.
[0054] In this embodiment, the slot 101 facilitates the user's transfer of the test tube rack and effectively reduces the possibility of direct contact with the test tubes, thereby ensuring the accuracy of the experimental results.
[0055] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
