Description

Technical Field

[0001] This utility model relates to the field of test tube storage tools, and in particular to a laboratory-specific storage and retrieval device. Background Technology

[0002] In routine laboratory sampling and other work, specialized test tubes are often required for experiments. These test tubes are typically made of glass, allowing for more direct observation of the reaction process and faster results. However, these glass test tubes are prone to rolling and breaking during storage. Therefore, specialized test tube racks are often used to secure them. However, commercially available test tube racks often lack precise adjustment for the length and height of the test tubes, easily resulting in tubes that are too short or too long being poorly secured and ultimately breaking.

[0003] In addition, the number of test tubes used in a single experiment is limited, and an excessively large test tube rack occupies a large amount of workspace, which is not conducive to the placement of experimental materials on the workspace.

[0004] Therefore, existing test tube racks have the technical problems of occupying a large space and not being able to adjust their height. Summary of the Invention

[0005] This utility model provides a laboratory-specific storage and retrieval device that solves the technical problems of existing test tube racks having large space requirements and no height adjustment.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A laboratory-specific access device includes a base, which is fixed to a table surface and has positioning holes.

[0008] A column, which is fixed to the base;

[0009] A support frame is rotatably connected to the column. The support frame is provided with a support hole that passes through the support frame. There are at least two support frames, and the at least two support frames are evenly distributed along the axial direction of the column.

[0010] The support frame is rotatably connected to the column via the locking assembly.

[0011] In each of the support frames, all of the support holes correspond to a portion of the positioning holes.

[0012] Preferably, the locking assembly includes a locking ring, which is sleeved on the column, and the support frame is disposed on the locking ring. Furthermore, the bottom surface of the upper locking ring of two adjacent locking rings contacts the top surface of the lower locking ring.

[0013] Preferably, the locking assembly further includes a locking groove disposed on the column, the locking groove being disposed along the axial direction of the column and evenly distributed along the circumference of the column. The locking assembly also includes a positioning portion disposed on the locking ring, the locking ring being provided with an elastic element for pushing the positioning portion into the locking groove, a portion of the positioning portion being located within the locking groove, and another portion of the positioning portion being located within the locking ring.

[0014] Preferably, the locking ring is provided with a positioning channel that cooperates with the positioning part, and the elastic element pushes the positioning part through the positioning channel into the locking groove.

[0015] Preferably, the positioning part is a positioning ball, and a rounded chamfer is provided between the locking groove and the side wall of the column to facilitate the positioning ball entering the locking groove or to facilitate the positioning ball leaving the locking groove.

[0016] Preferably, the locking ring is provided with an annular groove, the elastic element includes a ring body fixed to the locking ring, the elastic element also includes a spring piece extending into the annular groove, and the positioning part contacts the spring piece.

[0017] Preferably, the spring and the ring are an integral structure, the positioning channel communicates with the ring groove, the positioning parts are evenly distributed along the circumferential direction of the locking ring, and each positioning part corresponds to an independent spring.

[0018] Preferably, the ring body is fixed to the locking ring by screws, and there are two rows of screws, with the two rows of screws located on both sides of the ring groove.

[0019] Preferably, the ring body is provided with a protruding ridge, and there are two protruding ridges. The locking ring is provided with a groove that mates with the protruding ridge. There are two grooves, and each protruding ridge mates with an independent groove. The grooves are located on both sides of the ring groove.

[0020] Preferably, the upper end of the column is provided with a plug, the cross-sectional shape of the plug is polygonal, and the base is provided with a plug hole that mates with the plug.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By rotatably connecting the support frame to the column, and with all the support holes of the support frame corresponding to a portion of the positioning holes, and the support frame being evenly distributed along the axis of the column, when no test tubes are placed on some of the support frames, the support frame can be rotated to align with other support frames in the vertical direction, thereby allowing some support frames to be folded down, reducing the space occupied by the laboratory-specific storage device. Other items can be placed in the positions on the base where no test tubes are placed.

[0023] By setting the support frame along the axis of the vertical shaft, and rotatably connecting the support frame to the column via a locking assembly, which locks the support frame to a certain angle to support the test tubes, test tubes of different heights can be positioned using support frames located at different heights. This prevents the support frame from failing, allowing for convenient storage of test tubes of different heights without easily damaging them. Attached Figure Description

[0038] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0039] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0040] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0041] Reference Figures 1 to 9 As shown, a laboratory-specific storage and retrieval device includes a base 1, which is fixed to a table surface and has positioning holes 11.

[0042] Column 2, which is fixed to the base 1;

[0043] A support frame 3 is rotatably connected to the column 2. The support frame 3 is provided with a support hole 31, which passes through the support frame 3. There are at least two support frames 3, and the at least two support frames 3 are evenly distributed along the axial direction of the column 2.

[0044] The support frame 3 is rotatably connected to the column 2 via the locking assembly 32.

[0045] In this case, all the support holes 31 of each support frame 3 correspond to a portion of the positioning holes 11.

[0046] In some embodiments, the support frame 3 can be fan-shaped, or it can be elongated. The area of ​​a single support frame 3 is smaller than the area of ​​the base 1, so that the upper and lower support frames 3 can be aligned, thereby reducing the space occupied by the support frame 3 and allowing other items to be placed on the base 1. Folding the support frame 3 means that the upper and lower support frames 3 are stacked aligned.

[0047] In some embodiments, the base 1 can be fixed to the tabletop with screws. Alternatively, when the base 1 has sufficient weight to prevent the laboratory access device from tipping over, the base 1 can be placed directly on the tabletop without being fixed.

[0048] In some embodiments, the work surface may be a tabletop, which is the surface of a table used for experiments.

[0049] Reference Figures 1 to 9 As shown, in some embodiments, the locking assembly 32 includes a locking ring 321, which is sleeved on the column 2. The support frame 3 is disposed on the locking ring 321, and the bottom surface of the upper locking ring 321 of two adjacent locking rings 321 contacts the top surface of the lower locking ring 321.

[0050] In some embodiments, the support frame 3 may be integral with the locking ring 321. Alternatively, the support frame 3 may be welded to the locking ring 321, or the support frame 3 may be fixed to the locking ring 321 by a detachable connection, for example, by using threads to fix the support frame 3 to the locking ring 321.

[0051] In some embodiments, the locking ring 321, in addition to fixing the support frame 3 to the base 1, is also used to limit the height of the support frame 3 relative to the base 1. Since the support frame 3 has a certain thickness, the height of the support frame 3 relative to the base 1 is the sum of the heights of all the locking rings 321 below the support frame 3.

[0052] Reference Figures 1 to 9As shown, in some embodiments, since the test tube has the shortest specification, the height of the lowest support frame 3 is usually a certain distance from the base 1. Using the locking ring 321 to position the height of the lowest support frame 3 would result in an increase in the thickness of the locking ring 321. Therefore, the column 2 is provided with a stepped surface, and the locking ring 321 corresponding to the lowest support frame 3 contacts the stepped surface. That is, the bottom surface of the locking ring 321 corresponding to the lowest support frame 3 contacts the top surface of the stepped surface.

[0053] In some embodiments, the locking assembly 32 further includes a locking groove 322 disposed on the column 2. The locking groove 322 is disposed along the axial direction of the column 2 and is evenly distributed along the circumferential direction of the column 2. The locking assembly 32 also includes a positioning part 323 disposed on the locking ring 321. The locking ring 321 is provided with an elastic member 324 for pushing the positioning part 323 into the locking groove 322. A part of the positioning part 323 is located in the locking groove 322, and another part of the positioning part 323 is located in the locking ring 321.

[0054] In some embodiments, the locking ring 321 is provided with a positioning channel 3211 that cooperates with the positioning part 323, and the elastic member 324 pushes the positioning part 323 through the positioning channel 3211 into the locking groove 322.

[0055] Reference Figures 1 to 9 As shown, in some embodiments, the positioning part 323 is a positioning ball, and a rounded chamfer is provided between the locking groove 322 and the side wall of the column 2 to facilitate the positioning ball entering the locking groove 322 or to facilitate the positioning ball leaving the locking groove 322.

[0056] The positioning ball and the rounded chamfer design cause the reaction force exerted on the positioning ball by the side wall of the locking groove 322 when the locking ring 321 is rotated to be divided into two components. One component overcomes the elastic force of the elastic element 324, causing the positioning ball to disengage from the locking groove 322 and enter the next locking groove 322.

[0057] In some embodiments, the locking ring 321 is provided with an annular groove 3212, the elastic member 324 includes a ring body 3241, the ring body 3241 is fixed to the locking ring 321, the elastic member 324 also includes a spring piece 3242 extending into the annular groove 3212, and the positioning part 323 contacts the spring piece 3242.

[0058] In some embodiments, the spring piece 3242 and the ring body 3241 are integral structures, the positioning channel 3211 communicates with the ring groove 3212, the positioning parts 323 are evenly distributed along the circumferential direction of the locking ring 321, and each positioning part 323 corresponds to an independent spring piece 3242.

[0059] In some embodiments, the ring body 3241 is fixed to the locking ring 321 by screws, and there are two rows of screws, with the two rows of screws located on both sides of the ring groove 3212.

[0060] In some embodiments, the ring body 3241 is provided with a protruding rib 33, the protruding rib 33 has two rings, the locking ring 321 is provided with a groove 331 that mates with the protruding rib 33, there are two grooves 331, each ring of the protruding rib 33 mates with an independent groove 331, the groove 331 is located on both sides of the ring groove 3212.

[0061] The screws, protrusions 33, and grooves 331 allow the two sides of the annular groove 3212 to be effectively fixed to the ring 3241, thereby making the annular groove 3212 and the locking ring 321 less prone to deformation, and thus giving the locking ring 321 sufficient strength to position the support frame 3.

[0062] Reference Figures 1 to 9 As shown, in some embodiments, the locking groove 322 is oriented to correspond to the positioning hole 11 provided on the base 1. That is, when the positioning ball enters the locking groove 322, the support hole 31 on the support frame 3, which is positioned by the positioning ball, is aligned with a portion of the positioning hole 11 on the base 1, so that the test tube can be effectively positioned. That is, the lower end of the test tube enters the positioning hole 11, while the other part of the test tube is positioned by the support hole 31 on the support frame 3.

[0063] In some embodiments, the upper end of the column 2 is provided with a plug 21, the cross-sectional shape of the plug 21 is polygonal, and the base 1 is provided with a plug hole 12 that mates with the plug 21.

[0064] For large-scale experiments, when one laboratory access device cannot meet the needs, two laboratory access devices can be combined vertically using the insertion post 21 and the socket 12. Since the two laboratory access devices are positioned by the socket 12 and the insertion post 21, it is only necessary to fix the base 1 of the lower laboratory access device to the table surface.

[0065] In some embodiments, the cross-sectional shape of the insertion post 21 may also be circular. When the cross-sectional shape of the insertion post 21 is circular, in order to prevent the insertion post 21 from rotating relative to the insertion hole 12 on the other base 1, screws may be used for locking, or other fasteners may be used to lock the two laboratory-specific access devices.

[0066] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0067] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0068] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
