Abstract
Description
Technical Field
[0001] This utility model relates to the field of test tube placement box technology, and in particular to a stackable test tube box. Background Technology
[0002] In laboratory and medical settings, test tubes are a common experimental tool widely used in various experimental procedures and sample storage. While traditional test tube boxes meet basic storage needs to a certain extent, they have gradually revealed many problems in actual use, making them difficult to adapt to the efficient, safe, and convenient operational requirements of modern laboratories.
[0003] First, most existing test tube boxes are not stackable or have limited stacking capabilities. In space-constrained laboratory environments, a large number of test tube boxes typically occupy significant desktop or storage space, resulting in low space utilization. When several test tube boxes need to be stored, storing them individually not only wastes space but also increases the difficulty of management and retrieval.
[0004] Secondly, many traditional test tube boxes have poorly designed locking mechanisms, resulting in a loose connection between the lid and the box body. During handling or transportation, the lid can easily loosen or even open accidentally, exposing the test tubes and increasing the risk of breakage and sample contamination.
[0005] Therefore, those skilled in the art urgently need to provide a stackable test tube box that allows several test tube boxes to be stacked together vertically, and the lid and the box body to be securely locked together. Utility Model Content
[0006] The purpose of this invention is to provide a stackable test tube box, which allows several test tube boxes to be stacked together vertically, and the lid and the box body to be securely locked together.
[0007] To achieve the above objectives, this utility model provides a stackable test tube box, comprising a lid and a body. One end of the lid is rotatably connected to the body, and the other end is engaged with the top of the body. A limiting protrusion is provided on the top of the lid, and a limiting groove is provided on the bottom of the body. The limiting protrusion and the limiting groove are matched. Several test tube boxes are stacked vertically via the limiting groove and the limiting protrusion.
[0008] Preferably, the box body has engagement protrusions on both sides and engagement grooves on both sides of the box cover. The engagement protrusions and engagement grooves match each other, and the engagement protrusions and engagement grooves are rotatably connected together after being engaged.
[0009] Preferably, the lid has a first limiting groove on both sides, and the locking block is slidably connected to the first limiting groove; the top of the box body has a second limiting groove on both sides, and the lid and the box body are locked together by the locking block and the second limiting groove.
[0010] Preferably, the locking block includes an integrally formed push block and a limiting block. The push block slides inside the first limiting groove, and the limiting block slides along the second limiting groove after passing through the first limiting groove to lock the box cover and the box body together.
[0011] Preferably, the second limiting groove is stepped in shape.
[0012] Preferably, the interior of the box body is provided with several test tube placement grids, which are arranged in a matrix.
[0013] Preferably, two sets of markings are provided at the top edge of the box body, the two sets of markings are respectively arranged along the length direction and the width direction, and the markings correspond to the test tube placement grid.
[0014] Preferably, the test tube placement grid is square, and the bottom of the four inner walls of the test tube placement grid is provided with limiting protrusions. The limiting protrusions are located at the middle of the bottom of the inner wall of the test tube placement grid, and the outer wall of the limiting protrusions is provided with an arc-shaped surface. The arc-shaped surface is adapted to the bottom of the test tube, and the limiting protrusions support the test tube through the inclined arc-shaped surface.
[0015] The advantages and positive effects of the stackable test tube box described in this utility model are:
[0016] 1. By using the stepped limiting slide groove 2 in conjunction with the locking block, pushing the push block will allow the limiting block to slide along the limiting slide groove 2 to complete the locking or unlocking. The operation is simple and labor-saving, and the box lid can be opened and closed quickly without complicated operations, thus improving work efficiency.
[0017] 2. Several test tube boxes can be stacked vertically, with the limiting protrusion matching the limiting groove to achieve efficient space utilization, reduce the occupation of laboratory tabletops and storage space, and facilitate transportation, thereby reducing transportation costs.
[0018] 3. The bottom limiting protrusion of the test tube placement grid has an arc-shaped surface, which can smoothly contact the bottom of the test tube, increasing the stability of the test tube in the test tube placement grid.
[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0033] In this application, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.
[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0035] like Figure 1-8 As shown, a stackable test tube box includes a test tube box 1. The test tube box 1 includes a lid 2 and a body 3. One end of the lid 2 is rotatably connected to both sides of the body 3, and the other end of the lid 2 is engaged with the top of the body 3. The top of the lid 2 is provided with a limiting protrusion 203, and the bottom of the body 3 is provided with a limiting groove 304. The limiting protrusion 203 and the limiting groove 304 match, and several test tube boxes 1 are stacked together vertically through the limiting groove 304 and the limiting protrusion 203.
[0036] like Figure 2 , Figure 5 As shown, the box body 3 has engagement protrusions 301 on both sides and engagement grooves 202 on both sides. The engagement protrusions 301 and engagement grooves 202 match each other, and the engagement protrusions 301 and engagement grooves 202 are rotatably connected after they engage.
[0037] The lid 2 has a first limiting groove 201 on both sides, and the locking block 4 is slidably connected to the first limiting groove 201. The top of the box body 3 has a second limiting groove 302 on both sides, and the lid 2 and the box body 3 are locked together by the locking block 4 and the second limiting groove 302.
[0038] The locking block 4 includes an integrally formed push block 401 and a limiting block 402. The push block 401 is located within and slidably connected to the limiting slide groove 201. A limiting plate is provided at the connection between the limiting block 402 and the push block 401. The limiting plate is located below the limiting slide groove 201 to prevent the locking block 4 from easily slipping out of the limiting slide groove 201, thereby improving the stability of the locking. After passing through the limiting slide groove 201, the limiting block 402 slides along the limiting slide groove 302 to lock the box body 3 and the box cover 2 together.
[0039] like Figure 5As shown, the limiting slide groove 302 is stepped. The wider end of the limiting slide groove 302 has a larger opening than the width of the limiting block 402, allowing the limiting block 402 to slide out from the wider end, facilitating the opening of the box body 3 and the box lid 2. The narrower end of the limiting slide groove 302 has a narrower opening than the width of the limiting block 402. When the limiting block 402 slides to the narrower end, it cannot slide out from the narrower end, locking the box body 3 and the box lid 2. By engaging the stepped limiting slide groove 302 with the limiting block 402 on the locking block 4, pushing the push block 401 allows the limiting block 402 to slide along the limiting slide groove 302 to complete the engagement or unlocking.
[0040] Specifically, the top of the lid 2 is equipped with a lock or unlock indicator near the locking block 4, making it convenient for personnel to lock or unlock the locking block 4 according to the instructions.
[0041] like Figure 5 As shown, the interior of the box body 3 is provided with several test tube placement grids 303, which are arranged in a matrix.
[0042] Two sets of markings are provided at the top edge of the box body 3. The two sets of markings are set along the length direction and the width direction respectively, and the markings correspond to the test tube placement grid 303.
[0043] Specifically, the markings are set in ascending numerical order along the length direction and in alphabetical order along the width direction, which makes it easier for laboratory personnel to quickly locate specific test tubes, improve storage and retrieval efficiency, and save time.
[0044] like Figure 6 , Figure 7 As shown, the test tube placement grid 303 is square. Each of the four inner walls of the test tube placement grid 303 has a limiting protrusion 3031 at its bottom, located at the center of the bottom of the inner wall. The outer wall of the limiting protrusion 3031 has an arc-shaped surface that fits the bottom of the test tube. This arc-shaped surface allows for smooth contact with the bottom of the test tube, increasing the stability of the test tube within the grid. The side of the limiting protrusion 3031 closest to the test tube is inclined; the diameter of the circle formed by the top of the arc-shaped surface is larger than the outer diameter of the test tube, while the diameter of the circle formed by the bottom of the arc-shaped surface is smaller than the outer diameter of the test tube, facilitating support for the test tube.
[0045] The usage process of this utility model is as follows:
[0046] First, open the lid 2. By pushing the push block 401 to move in the unlocking direction, the limiting block 402 moves along the limiting slide groove 302, thereby unlocking the lid 2 and the box body 3, and thus opening the lid 2.
[0047] Next, place the test tube inside the test tube placement grid 303. The limiting protrusion 3031 at the bottom of the test tube placement grid 303 serves to limit the bottom of the test tube. The arc-shaped surface can make smooth contact with the bottom of the test tube, increasing the stability of the test tube inside the test tube placement grid 303.
[0048] Then, close the lid 2, and push the push block 401 to move in the locking direction, causing the limit block 402 to move in the opposite direction along the limit slide groove 302, so that the lid 2 and the box body 3 are locked, thereby locking the lid 2 onto the box body 3.
[0049] Finally, several test tube boxes 1 can be stacked together in the vertical direction by means of matching limiting protrusions 203 and limiting grooves 304 on the test tube boxes 1.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the 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 still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
