Description

Technical Field

[0001] The utility model relates to the technical field of standard solution storage boxes, in particular to a stacking structure of standard solution storage boxes. Background Art

[0002] A standard solution is a reagent solution with a precisely known concentration. Standard solutions are stored in standard solution storage bottles. When stocking standard solutions in bulk, these bottles need to be placed in storage boxes. To save space, multiple storage boxes are stacked together.

[0003] The stacked storage boxes are unstable, easy to fall over, and inconvenient to carry. After searching, it was found that in the patent with the announcement number CN220333309U, a modular biological reagent box stacking structure is disclosed. Figure 1 In this patent, the four corners of all the stacked test kits are connected in series on four threaded rods 3. The bottom test kit is supported by the base, and the top test kit is covered with a top cover 1. The top cover 1 is also penetrated by four threaded rods 3. The tops of the four threaded rods 3 are threadedly connected with hand-tightening nuts 31. The hand-tightening nuts 31 are pressed on the top cover 1, so that all the test kits are clamped between the base and the top cover 1. In addition, all the test kits are surrounded by four threaded rods 3 on all sides, which can not only improve the stacking stability, but also facilitate carrying by pulling the handle on the top cover 1.

[0004] However, in the aforementioned patent, during assembly, four threaded rods 3 must be threaded through the stacked reagent cartridges and the top cover 1, and four hand-tightening nuts 31 must be screwed onto the tops of the four threaded rods 3. During disassembly, the four hand-tightening nuts 31 must be screwed in the opposite direction before the top cover 1 and the reagent cartridges are removed from the threaded rods 3. Since four sets of threaded rods 3 and hand-tightening nuts 31 are provided, both assembly and disassembly operations are cumbersome, reducing assembly and disassembly efficiency.

[0005] Therefore, how to improve assembly efficiency and disassembly efficiency is a technical problem that needs to be solved at present. Utility Model Content

[0051] To better understand the present invention, the present invention is further described below with reference to the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are used solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0052] Example 1:

[0053] A stacking structure of standard solution storage boxes, see Figure 12 and Figure 9 , including a top cover 1, a screw barrel 2 is welded and fixed to the middle of the top surface of the top cover 1, and a threaded rod 3 is connected to the inner thread of the screw barrel 2.

[0054] See also Figure 7 and Figure 9 Two stoppers and an adjustment block 5 are provided on the upper portion of the threaded rod 3. Both stoppers utilize nuts 4, which are threadedly connected to the threaded rod 3. The adjustment block 5 is positioned between the two nuts 4 and has a rotation hole 51 defined therein, which rotatably engages the threaded rod 3. Clamped by the two nuts 4, the adjustment block 5 is prevented from moving axially along the threaded rod 3.

[0055] See also Figure 7 and Figure 9 In order to reduce the total thickness of the two nuts 4 and one adjusting block 5, a receiving groove 52 is provided on the top and bottom surfaces of the adjusting block 5. The nut 4 is arranged in the receiving groove 52, so that the thickness of the nut 4 is hidden in the thickness of the adjusting block 5, thereby reducing the total thickness of the two nuts 4 and one adjusting block 5.

[0056] See also Figure 5 and Figure 9 In order to facilitate the screwing of the threaded rod 3 and to facilitate the lifting of the threaded rod 3, a handle 6 is welded and fixed on the top of the threaded rod 3, and two nuts 4 and an adjusting block 5 are located below the handle 6.

[0057] See also Figure 9The four side walls of the adjusting block 5 are rotatably connected to the adjusting rod 7, the lower end of the adjusting rod 7 is rotatably connected to the cross bar 8, the cross bar 8 is slidably matched with the dovetail groove 11 set on the top surface of the top cover 1, and the long sides of the cross bar 8 and the long sides of the dovetail groove 11 both extend along the radial direction of the screw barrel 2. Figure 2 、 Figure 3 and Figure 4 The horizontal bar 8 is welded and fixed with a vertical bar 9 at one end away from the adjusting rod 7, and the lower end of the vertical bar 9 is welded and fixed with a supporting plate 10.

[0058] See also Figure 12 , a plurality of storage boxes 20 are stacked on the supporting plate 10. Figure 10 and Figure 11 The storage box 20 comprises a box body 201 and a box lid 202. The top surface of the box body 201 is provided with a matrix of placement holes 2011, into which the standard solution storage bottle 30 is placed. The bottom surface of the box body 201 is provided with a groove 2012, and the bottoms of the four side walls of the box body 201 are each provided with a socket 2013. The box lid 202 is buckled onto the box body 201, and the top surface of the box lid 202 is provided with a boss 2021, which is an integral structure with the box lid 202.

[0059] The working principle of this embodiment 1 is as follows:

[0060] (1) When folding a plurality of storage boxes 20 using the stacking structure of Example 1:

[0061] First, the user stacks a plurality of storage boxes 20. When stacking the storage boxes 20, the groove 2012 of the box body 201 in the upper storage box 20 is buckled onto the boss 2021 of the box cover 202 in the lower storage box 20. The buckling of the groove 2012 and the boss 2021 prevents the two adjacent storage boxes 20 from shifting in the plane direction, thereby improving the stability of the stacked storage boxes 20.

[0062] Then, the user places the top cover 1 on the topmost storage box 20 and screws the threaded rod 3 upwards. In the process of screwing the threaded rod 3 upwards, the threaded rod 3 drives the two nuts 4 to move upwards, and the two nuts 4 clamp the adjustment block 5 to move upwards. The adjustment block 5 pulls the upper ends of the four adjustment rods 7 upwards, and the lower ends of the four adjustment rods 7 gradually approach the screw barrel 2. The four adjustment rods 7 drive the cross rod 8 to move closer to the screw barrel 2. The cross rod 8 drives the vertical rod 9 to approach the storage box 20. The vertical rod 9 drives the support plate 10 to insert into the insertion hole 2013 of the lowest storage box 20, so that all storage boxes 20 are supported by the support plate 10, and all storage boxes 20 are surrounded by the vertical rods 9.

[0063] When all the storage boxes 20 are transferred, the user is allowed to directly carry away all the stacked storage boxes 20 by lifting the threaded rods 3 , which is convenient for carrying.

[0064] (2) When all storage boxes 20 are released using the stacking structure of Example 1:

[0065] First, the user screws the threaded rod 3 downward. In the process of screwing the threaded rod 3 downward, the threaded rod 3 drives the two nuts 4 to move downward, and the two nuts 4 clamp the adjusting block 5 to move downward. The adjusting block 5 pushes the upper ends of the four adjusting rods 7 to move downward, and the lower ends of the four adjusting rods 7 gradually leave the screw barrel 2. The four adjusting rods 7 drive the cross rod 8 to leave the screw barrel 2 together, the cross rod 8 drives the vertical rod 9 to leave the storage box 20, and the vertical rod 9 drives the support plate 10 to withdraw from the socket 2013 of the bottom storage box 20.

[0066] Then, the user removes the top cover 1 from the uppermost storage box 20 . At this time, the user can freely take out the standard solution storage bottle 30 in the storage box 20 .

[0067] Through the above working principle of Example 1, it can be seen that this Example 1 has the following effects:

[0068] In this embodiment 1, only one threaded rod 3 needs to be screwed upwards to allow the support plate 10 to support all the stacked storage boxes 20, and the vertical rods 9 need to be arranged around the sides of all the storage boxes 20 to complete the assembly. The assembly operation is simple and helps to improve assembly efficiency. When disassembling, only one threaded rod 3 needs to be screwed downwards to allow the support plate 10 to separate from the storage boxes 20, and the vertical rods 9 need to be removed from the storage boxes 20 to complete the disassembly. The disassembly operation is simple and helps to improve disassembly efficiency.

[0069] In addition, when the stacking structure of this embodiment 1 is placed on a desktop, the bottom of the box body 201 and the bottom of the supporting plate 10 can both be in contact with the desktop through the plug-in cooperation with the supporting plate 10 and the socket 2013. Compared with only the supporting plate 10 being in contact with the desktop, the contact area is increased and the stability is improved.

[0070] Example 2:

[0071] This embodiment 2 is further improved on the basis of embodiment 1:

[0072] See also Figure 2 In this embodiment 2, the vertical rod 9 includes a sleeve 91 and an inner rod 92. The top of the sleeve 91 is welded and fixed to the crossbar 8, the inner rod 92 is vertically slidably fitted with the sleeve 91, and the bottom of the inner rod 92 is welded and fixed with the supporting plate 10. The side of the sleeve 91 facing the storage box 20 is flush with the side of the inner rod 92 facing the storage box 20. Figure 8The sleeve 91 is provided with a screw hole 911 on the side facing away from the storage box 20 , and a bolt 93 is connected to the inner thread of the screw hole 911 . The bolt 93 abuts against the side of the inner rod 92 facing away from the storage box 20 .

[0073] By providing a sleeve 91, an inner rod 92, and a bolt 93, the length of the vertical rod 9 can be adjusted, thereby making the spacing between the support plate 10 and the top cover 1 adjustable. The longer the vertical rod 9 is, the larger the spacing between the support plate 10 and the top cover 1 is, and the more storage boxes 20 can be accommodated between the support plate 10 and the top cover 1, thereby improving the flexibility of use.

[0074] When increasing the length of the vertical rod 9, the operation is as follows: first, the user screws the bolt 93 outward so that the bolt 93 leaves the inner rod 92. At this time, the inner rod 92 can move freely up and down in the vertical direction inside the sleeve 91; then, the user pulls the inner rod 92 downward to increase the overall length of the vertical rod 9; finally, the user screws the bolt 93 in the opposite direction, and the bolt 93 re-contacts the side of the inner rod 92. At this time, the friction between the bolt 93 and the side of the inner rod 92 can prevent the inner rod 92 from sliding inside the sleeve 91, thereby completing the length adjustment of the vertical rod 9.

[0075] See also Figure 2 and Figure 8 To increase the reliability of the bolt 93 locking the inner rod 92, a plurality of positioning grooves 921 evenly distributed along the vertical direction are provided on the side of the inner rod 92 facing away from the storage box 20. When the bolt 93 is used to lock the inner rod 92, the bolt 93 is screwed into the positioning groove 921. At this time, the groove wall of the positioning groove 921 is blocked by the bolt 93 in the vertical direction, preventing the inner rod 92 from sliding vertically inside the sleeve 91, thereby improving the reliability of the bolt 93 locking the inner rod 92.

[0076] See also Figure 2 In order to facilitate the observation of the remaining length of the inner rod 92 inside the sleeve 91, the sleeve 91 is provided with an observation hole 912 on the side away from the storage box 20. The inner rod 92 can be exposed from the observation hole 912, making it convenient for users to observe the remaining length of the inner rod 92 inside the sleeve 91.

[0077] For further information, see Figure 2 The top of the inner rod 92 is provided with a limiting ridge 922, which is arranged in the observation hole 912 and vertically slides with the observation hole 912. The provision of the limiting ridge 922 can prevent the inner rod 92 from completely falling out of the sleeve 91, and then prevent the storage box 20 from falling, thereby improving the reliability of use.

[0078] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
