Description

Technical Field

[0001] This utility model relates to the technical field of test tube racks, and in particular to a laboratory test tube rack. Background Technology

[0002] Test tubes are an indispensable piece of equipment in chemistry laboratories, primarily used as containers to hold small amounts of chemical reagents for reactions. These test tubes can be used at room temperature or under heating. There are many types of test tubes, including but not limited to ordinary test tubes, side-braced test tubes, and centrifuge tubes. Each type of test tube has its specific purpose and design to suit different experimental needs. However, most commercially available test tube racks are designed with fixed, non-removable dimensions, meaning they can only accommodate test tubes of specific sizes. This design has poor compatibility with test tubes of different diameters and lengths. Therefore, when conducting experiments requiring test tubes of various sizes, researchers have to prepare multiple test tube racks of different sizes, which not only increases experimental costs but also occupies valuable space. Furthermore, traditional test tube racks have relatively limited functionality; they mainly serve to place and support ordinary test tubes. Centrifuge tubes, which are frequently used in experiments, need to be placed separately on centrifuge racks, a practice that lacks flexibility and limits the convenience of experimental operations. Therefore, the design and function of test tube racks urgently need to be improved to meet the diverse and efficient needs of modern chemical experiments. Utility Model Content

[0003] The present invention addresses the aforementioned shortcomings of existing technologies by providing a laboratory test tube rack that overcomes the problem of poor versatility of existing test tube racks for test tubes of different specifications. It can flexibly adapt to test tubes of various diameters and lengths, eliminating the need to prepare multiple test tube racks for different specifications, thus reducing experimental costs and space occupation.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0005] A laboratory test tube rack includes a U-shaped base frame with multiple clips arranged in a two-dimensional array along a vertical plane. A rack plate is detachably connected to two horizontally adjacent clips via fasteners. Multiple slots are selectively provided on the rack plate, with the openings of the slots mate with the walls of the test tubes. The bottom wall of the U-shaped base frame and / or the surface of the rack plate are positioned opposite the bottom of the test tubes.

[0006] By adopting the above technical solution, firstly, depending on the diameter of the test tubes, a rack plate with slots matching the diameter can be selected and installed on the clips using fasteners. Secondly, depending on the length of the test tubes, a rack plate with slots matching the diameter can be selected, or a rack plate without slots can be used. This allows the test tubes to be inserted into the upper rack plate, with their bottoms resting on the bottom wall of the U-shaped base or the surface of the lower rack plate. This ensures that the tops of all the test tubes on the rack are approximately in the same height area, facilitating sampling or loading. This design allows the test tube rack of this invention to flexibly adapt to test tubes of different diameters and lengths, eliminating the need to prepare multiple test tube racks for different specifications of test tubes, thereby reducing experimental costs and space occupation.

[0007] The present invention is further configured such that at least two fasteners are provided between the card strip and the frame plate, and the at least two fasteners are arranged at intervals along the length direction of the card strip.

[0008] By adopting the above technical solution, the fasteners can firmly lock the rack plate onto the clips, preventing the rack plate from shaking or falling off during use. At the same time, since the fasteners are arranged at intervals along the length of the clips, even if one fastener fails, the others can still maintain the stable installation of the rack plate, thereby improving the reliability and service life of the entire test tube rack. In addition, this design also makes it easy for users to quickly disassemble and replace the rack plates as needed to accommodate test tubes of different sizes, further improving the flexibility and practicality of the test tube rack.

[0009] The present invention is further configured such that: the fastener includes a limiting hole formed on the frame plate, a flexible limiting post disposed on the clip and inserted into the limiting hole, and a flexible limiting terminal disposed on the limiting post and abutting against the surface of the frame plate.

[0010] By adopting the above technical solution, the flexible limiting posts and terminals not only improve the ease of installation of the fasteners, but the flexible material also increases the friction between the fasteners and the rack and locking strips, thereby improving the locking effect of the fasteners. When the rack needs to be disassembled, the user only needs to apply slight force to deform the limiting terminals, thereby disengaging the limiting posts from the limiting holes and achieving quick disassembly of the rack. This design makes the assembly and disassembly of the test tube rack simpler and faster, further improving the practicality and user experience of the test tube rack.

[0011] The present invention is further configured such that the fastener also includes a deformation groove that passes through the limiting post and the limiting terminal.

[0012] By adopting the above technical solution, the deformation groove makes it easier for the limiting post and limiting terminal to deform under external force, thereby reducing the force required to disassemble the frame plate and further improving the ease of disassembly.

[0013] The present invention is further configured such that the buckle also includes a guide surface disposed on the end face of the limiting terminal.

[0014] By adopting the above technical solution, the guide surface is designed so that the limiting terminal can gradually deform along the guide surface during the process of inserting the limiting post into the limiting hole until the limiting terminal completely abuts against the surface of the frame plate. This achieves a smooth transition between the limiting terminal and the frame plate, avoiding installation difficulties or damage to the fasteners caused by the sudden deformation of the limiting terminal during installation.

[0015] The present invention is further configured such that the plate surface of the frame plate protrudes from the side near the card strip and is embedded between two horizontally adjacent card strips.

[0016] By adopting the above technical solution, the cross-section of the shelf plate is approximately T-shaped. This structural design not only enhances the connection stability between the shelf plate and the clips, but also effectively prevents the shelf plate from shaking or falling off during use, further improving the overall stability and safety of the test tube rack.

[0017] The present invention is further configured such that: the frame plate is provided with multiple plates and is arranged at intervals along the length direction of the card strip.

[0018] By adopting the above technical solution, multiple racks are arranged at equal intervals along the length of the card strip. This layout not only allows the test tube rack to accommodate more test tubes, but also ensures that each test tube has independent and stable support, avoiding mutual interference or collision between test tubes, and further improving the safety and stability of test tubes during storage and transportation.

[0019] The present invention is further configured such that the plurality of slots are arranged in a two-dimensional array along the horizontal plane.

[0020] By adopting the above technical solution, the slots on the test tube rack can be arranged according to a preset layout. This arrangement not only greatly improves the space utilization of the test tube rack, but also makes it easier for users to quickly find the appropriate slot position according to actual needs, further improving the efficiency and convenience of laboratory work. At the same time, the two-dimensional array arrangement also makes the test tube rack more uniform in appearance and enhances its aesthetics.

[0021] In summary, the beneficial technical effects of this utility model are as follows: This utility model solves the problem of poor universality of existing test tube racks for test tubes of different specifications, and can flexibly adapt to test tubes of various diameters and lengths, eliminating the need to prepare multiple test tube racks for test tubes of different specifications, which helps to reduce experimental costs and space occupation.

[0025] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figure 1 This utility model discloses a laboratory test tube rack, comprising a U-shaped base frame 1, four retaining strips 2 disposed on the U-shaped base frame 1, three shelf plates 4 detachably connected to two horizontally adjacent retaining strips 2 via fasteners 3, and multiple slots 5 selectively formed on the shelf plates 4. The four retaining strips 2 are arranged in a two-dimensional array along the vertical plane, the three shelf plates 4 are arranged at intervals along the length of the retaining strips 2, and the slots 5 are arranged in a two-dimensional array along the horizontal plane. Furthermore, to allow the test tube rack to flexibly adapt to test tubes of different diameters and lengths, the openings of the slots 5 are arranged to fit the test tube walls, and the bottom wall of the U-shaped base frame 1 and / or the surface of the shelf plates 4 are arranged relative to the bottom end of the test tube.

[0027] First, depending on the diameter of the test tubes, a shelf plate 4 with a matching slot 5 can be selected and assembled onto the clip 2 using a buckle 3. Then, depending on the length of the test tubes, a shelf plate 4 with a matching slot 5 can be selected, or a shelf plate 4 without a slot 5 can be used. This allows the test tubes to be inserted into the upper shelf plate 4, with their bottoms resting on the bottom wall of the U-shaped base frame 1 or the surface of the lower shelf plate 4. This ensures that the tops of all the test tubes on the test tube rack are approximately in the same height area, facilitating sampling or loading. This design allows the test tube rack of this invention to flexibly adapt to test tubes of different diameters and lengths, eliminating the need to prepare multiple test tube racks for different specifications of test tubes, thereby reducing experimental costs and space occupation.

[0028] Reference Figure 2 Two fasteners 3 are provided between the clip 2 and the shelf 4, and these two fasteners 3 are arranged at intervals along the length of the clip 2. The fasteners 3 can firmly lock the shelf 4 onto the clip 2, preventing the shelf 4 from shaking or falling off during use. At the same time, because the fasteners 3 are arranged at intervals along the length of the clip 2, even if one fastener 3 fails, the other fasteners 3 can still maintain the stable installation of the shelf 4, thereby improving the reliability and service life of the entire test tube rack. In addition, this design also allows users to quickly disassemble and replace the shelf 4 as needed to accommodate test tubes of different sizes, further improving the flexibility and practicality of the test tube rack. Specifically, the fastener 3 includes a limiting hole 31 opened on the frame plate 4, a flexible limiting post 32 disposed on the clip 2 and inserted into the limiting hole 31, a flexible limiting terminal 33 disposed on the limiting post 32 and abutting against the plate surface of the frame plate 4, a deformation groove 34 passing through the limiting post 32 and the limiting terminal 33, and a guide surface 35 disposed on the end face of the limiting terminal 33.

[0029] The guide surface 35 allows the limiting terminal 33 to gradually deform along the guide surface 35 during the insertion of the limiting post 32 into the limiting hole 31, until the limiting terminal 33 fully contacts the surface of the frame plate 4. This achieves a smooth transition between the limiting terminal 33 and the frame plate 4, avoiding installation difficulties or damage to the fastener 3 caused by sudden deformation of the limiting terminal 33 during installation. The flexible limiting post 32 and limiting terminal 33 not only improve the ease of installation of the fastener 3, but the flexible material also increases the friction between the fastener 3 and the frame plate 4 and the locking strip 2, thereby improving the locking effect of the fastener 3. When the frame plate 4 needs to be disassembled, the user only needs to apply slight force to deform the limiting terminal 33, causing the limiting post 32 to disengage from the limiting hole 31, enabling quick disassembly of the frame plate 4. Meanwhile, the deformation slot 34 makes it easier for the limiting post 32 and the limiting terminal 33 to deform under external force, thereby reducing the force required to disassemble the shelf plate 4 and further improving the ease of disassembly. This design makes the assembly and disassembly process of the test tube rack simpler and faster, further improving the practicality and user experience of the test tube rack.

[0030] In addition, the side of the shelf plate 4 closest to the clip 2 protrudes and is embedded between two horizontally adjacent clips 2. The cross-section of the shelf plate 4 is approximately T-shaped. This structural design not only enhances the connection stability between the shelf plate 4 and the clip 2, but also effectively prevents the shelf plate 4 from shaking or falling off during use, further improving the overall stability and safety of the test tube rack.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
