Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, and in particular to a modular test tube rack that is easy to disassemble. Background Technology

[0002] Test tubes and test tube racks are common tools in laboratories. In daily testing in biochemistry labs, test tubes are typically used for the sampling and storage of microorganisms. Test tubes are generally hollow cylinders with a QR code or barcode affixed to their outer wall for identification. When using test tubes, lab personnel usually place them on test tube racks. Test tube racks can hold multiple test tubes in an array, facilitating the removal and inspection of test tubes during experiments.

[0003] However, traditional test tube racks mostly use a one-piece molded fixed slot design, with fixed spacing, number of layers, and hole diameter specifications. This makes them incompatible with test tubes of different diameters (e.g., 10mm, 15mm, 20mm) or heights (e.g., regular test tubes, centrifuge tubes, colorimetric tubes). Multiple test tube racks need to be prepared for different experiments, leading to resource waste and increased laboratory costs. While some modular test tube racks are available on the market that can accommodate test tubes of various sizes, existing modular test tube racks generally rely on mechanical connections such as clips and bolts. Replacing or adjusting test tube modules requires tools such as screwdrivers, making disassembly time-consuming. Frequent disassembly and assembly can lead to clip wear and loose connections, affecting stability and hindering the quick disassembly and use of modular test tube racks. Utility Model Content

[0004] To address the technical problems of existing traditional test tube racks being incompatible with test tubes of different diameters or heights, and the time-consuming disassembly of modular test tube racks hindering their rapid disassembly and use, this utility model provides the following technical solution.

[0005] This utility model discloses a modular test tube rack that is easy to disassemble. It includes a base with several first permanent magnets fixedly mounted on its upper part and several module plates located above the base. A top plate with several second test tube holes is connected above the module plates. The module plates have several first test tube holes that match the axial direction of the second test tube holes. Elastic rings are provided on the inner walls of both the first and second test tube holes. Several connecting posts, magnetically attracted and fixed to the first permanent magnets, are fixedly connected to the lower part of the module plates. Several second permanent magnets are mounted on the upper part of the module plates. Several connecting posts, magnetically attracted and fixed to the second permanent magnets, are fixedly connected to the lower part of the top plate. Limiting rings that restrict the lower ends of the connecting posts are provided on the upper part of both the base and the upper part of the module plates.

[0006] As a further technical solution, the elastic ring is provided with a plurality of clamping posts arranged in a ring in the inner ring direction.

[0007] As a further technical solution, the limiting ring is provided with a plurality of engaging grooves in the radial direction, and the lower end of the connecting column is provided with a plurality of engaging blocks that match the engaging grooves.

[0008] As a further technical solution, the lower part of the connecting column is provided with a second fixing groove, and an iron sheet that is magnetically attracted and fixed to the first permanent magnet is fixed in the second fixing groove.

[0009] As a further technical solution, the upper part of the base is provided with a flexible plate, and the flexible plate is provided with a number of receiving grooves that match the axial direction of the first test tube hole.

[0010] As a further technical solution, specification stickers are provided on one side of the upper surface of both the module board and the top board.

[0011] The beneficial effects of this utility model are as follows: The modular plate and top plate of this utility model are respectively provided with a plurality of first test tube holes and second test tube holes that are axially matched. An elastic ring is circumferentially fixedly connected to the inner wall of each of the first and second test tube holes, and multiple clamping posts are circumferentially provided on the inner wall of the elastic ring, allowing the first and second test tube holes to accommodate test tubes of different diameters. Furthermore, the base can be connected to and replaced with modular plates and top plates of different hole diameters, and the number of modular plate layers can be increased or decreased, enabling the test tube rack to accommodate a wider range of test tubes, centrifuge tubes, colorimetric tubes, and other containers, thus improving the compatibility of the test tube rack. The iron plate at the lower end of the connecting post can be magnetically fixed to a first or second permanent magnet, facilitating the modular and rapid disassembly of the test tube rack, thereby improving the efficiency of the assembly and disassembly operations. The locking block at the lower end of the connecting post matches the radial locking groove of the limiting ring, preventing the connecting post from shaking due to accidental contact or vibration, ensuring the safe use of the test tube rack.

[0015] like Figure 1 As shown, this utility model discloses a modular test tube rack that is easy to disassemble, including a base 1 and an anti-slip pad located at the bottom of the base 1. The base 1 is made of ABS plastic, and the anti-slip pad has anti-slip textures or bumps to prevent the test tube rack from being placed stably on the laboratory table.

[0016] In a preferred embodiment, a plurality of module plates 2 are connected above the base 1. In this embodiment, there is one module plate 2, but more module plates 2 can be stacked according to actual needs. A top plate 3 with a plurality of second test tube holes 301 is connected above the module plate 2. The module plate 2 has a plurality of first test tube holes 201 that match the axial direction of the second test tube holes 301. The number of first test tube holes 201 and second test tube holes 301 is the same, and they correspond one-to-one in the vertical direction. Test tubes can pass through the second test tube holes 301 and the first test tube holes 201 and be stably clamped.

[0017] like Figure 3As shown, in a preferred embodiment, the inner walls of both the first test tube hole 201 and the second test tube hole 301 are provided with elastic rings 6. Several clamping posts 601 are arranged in a ring-like pattern within the inner circumference of the elastic rings 6. The clamping posts 601 are also elastic. The elastic rings 6 and the clamping posts 601 are made of uniform silicone material. Within their elastic extension range, the elastic rings 6 and the clamping posts 601 can clamp various test tubes of different sizes, allowing the first test tube hole 201 and the second test tube hole 301 to accommodate test tubes of different diameters. Simultaneously, the base 1 can be detached and replaced with module plates 2 and top plates 3 of different hole diameters, and the number of layers of module plates 2 can be increased or decreased, enabling the test tube rack to accommodate a wider range of test tubes, centrifuge tubes, colorimetric tubes, and other containers, thus improving the compatibility of the test tube rack.

[0018] In a preferred embodiment, a flexible plate 7 is provided on the upper part of the base 1. The flexible plate 7 has several receiving grooves 701 that match the axial direction of the first test tube hole 201. The receiving grooves 701 are used to receive the bottom of the test tube, making the test tube more stable in the first test tube hole 201 and the second test tube hole 301. At the same time, a specification sticker 8 is provided on one side of the upper surface of the module plate 2 and the top plate 3. The specification sticker 8 can indicate the diameter range of the test tubes that the module plate 2 and the top plate 3 are adapted to, which facilitates the disassembly and replacement of the module plate 2 and the top plate 3 according to the diameter of the test tube.

[0019] like Figure 2 and Figure 5 As shown, in a preferred embodiment, the upper part of the base 1 is fixedly provided with a plurality of first fixing slots 101. In this embodiment, there are four first fixing slots 101, and each first fixing slot 101 is fixed with a first permanent magnet 102. The first permanent magnet 102 is a strong magnet with a cylindrical structure. At this time, the lower part of the module plate 2 is fixedly connected with four connecting posts 501 that are magnetically attracted to the first permanent magnets 102. The lower part of the connecting posts 501 is provided with a second fixing slot 501, and an iron piece 502 that is magnetically attracted to the first permanent magnets 102 is fixed in the second fixing slot 501. Thus, the connecting posts 5 can be stably connected to the base 1.

[0020] The upper part of the module plate 2 is provided with four second permanent magnets 202. The second permanent magnets 202 have the same structure as the first permanent magnets 102, and the second permanent magnets 202 are fixed in the grooves of the module plate 2. At this time, the lower part of the top plate 3 is fixedly connected with several connecting posts 5 that are magnetically fixed to the second permanent magnets 202. The connecting posts 5 at the lower part of the top plate 3 have the same structure as the connecting posts 5 at the lower part of the module plate 2.

[0021] like Figure 4 and Figure 5As shown, in a preferred embodiment, to prevent the connecting post 5 from shifting horizontally due to accidental contact, both the upper part of the base 1 and the upper part of the module plate 2 are provided with limiting rings 4 to restrict the lower end of the connecting post 5. The connecting post 5 can be placed into the limiting ring 4 by holding the module plate 2. To improve the stability of the module plate 2 relative to the base 1, the limiting ring 4 is provided with several engaging grooves 401 radially, and the lower outer wall of the connecting post 5 is provided with several engaging blocks 503 that match the engaging grooves 401. Thus, the limiting ring 4 can more stably limit the connecting post 5, ensuring the stability of the test tube within the first test tube hole 201 in the module plate 2. The upper part of the module plate 2 is also provided with a limiting ring 4 to limit the connecting post 5 at the lower part of the top plate 3.

[0022] When disassembling this utility model, the top plate 3 can be separated from the module plate 2 simply by holding the top plate 3 and lifting it with force; the module plate 2 can be separated from the base 1 simply by holding the module plate 2 and lifting it with force. The disassembly time is only 1-3 seconds, which greatly improves the disassembly and installation speed of the modular test tube rack, facilitates the rapid modular disassembly of the test tube rack, and improves the efficiency of the disassembly and assembly operation of the test tube rack.
