Description

Technical Field

[0001] This utility model relates to the technical field of experimental consumable packaging devices, specifically to a stacking carrier for matching long and short suction heads. Background Technology

[0002] Pipette tips are tools used for aspirating and transferring liquids, and are among the most commonly used consumable equipment in laboratories. For ease of use in experiments, tip boxes are typically used to ensure a certain quantity of pipette tips in batches. Common tip boxes are generally rectangular, as disclosed in Chinese patents CN201810315554.9 and CN201220012195.8. However, for consumables like pipette tips, individually packaging each batch is inconvenient and unnecessary, requiring unpacking for each use, and also increases costs. Therefore, a stackable tip box, as disclosed in publication number CN 218962694 U, maximizes the number of pipette tips by stacking them, improving unpacking efficiency and saving packaging costs.

[0003] The problem with existing technology is that stackable pipette tip boxes have a single height and a single dimension, while existing pipette tips are not of a single dimension. Often, a single experiment may require pipette tips of different sizes and capacities to be used together. Since pipette tips of different lengths are usually packaged separately, this necessitates different sized packaging boxes. Separating them by size requires independent molding, which increases packaging costs and necessitates unpacking each box, causing inconvenience. Furthermore, pipette tip boxes typically contain a large number of tips. When only a small number of long and short tips are needed for each experiment, unpacking long tips and short tips separately can result in a large number of unused tips, leading to contamination and waste, which is detrimental to practical needs. Therefore, single-size stackable pipette tip boxes cannot solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a stacked carrier for matching long and short suction heads.

[0005] The objective of this utility model is achieved through the following technical solution: A mounting frame for matching long and short suction heads includes a bottom box and a lid that can be fitted together. A set of stacked mounting units is provided between the bottom box and the lid. Each mounting unit includes a main mounting plate and a secondary mounting plate. The secondary mounting plate is detachably disposed at the bottom of the main mounting plate. A set of first insertion holes is vertically disposed in the main mounting plate, and a set of second insertion holes is disposed in the secondary mounting plate. The set of first insertion holes and the set of second insertion holes are directly opposite each other, and the inner diameter of the first insertion hole and the second insertion hole are both smaller than the outer diameter of the suction head and larger than the outer diameter of the suction head rod. The suction head is confined between the two mounting units, and the rods of the upper and lower suction heads are not in contact with each other.

[0006] Preferably, the main carrier plate includes a receiving cavity, the first insertion hole is disposed in the upper half of the receiving cavity, and the lower half of the receiving cavity extends downward to form a first extension wall.

[0007] Preferably, the upper half of the sub-carrier plate extends upward to form a second extension wall, and the top opening of the second extension wall forms a snap-fit ​​that matches the bottom of the first extension wall, and the snap-fit ​​is engaged with the bottom of the first extension wall through the snap-fit.

[0008] Preferably, the inner wall of the second extension wall has a first stepped surface, and the bottom of the first extension wall abuts against the first stepped surface.

[0009] Preferably, the inner diameter of the first socket gradually decreases from top to bottom.

[0010] Preferably, the top of the inner wall of the base box forms a third stepped surface that matches the bottom of the sub-carrier plate, and the sub-carrier plate is movably engaged within the base box.

[0011] Preferably, the top side of the bottom box is provided with a limiting groove, and the two sides of the main carrier plate are symmetrically provided with ears, the bottom of the ears being movably engaged in the limiting groove.

[0012] Preferably, the bottom of the sub-carrier plate is provided with a limiting post protruding downwards, and the top of the main carrier plate is provided with a limiting hole that matches the limiting post. When a group of carrier units are stacked layer by layer, the limiting post is locked in the limiting hole.

[0013] The beneficial effects of this utility model are mainly reflected in: 1. A sub-carrier plate is detachably installed at the bottom of the main carrier plate, so that the main carrier plate can be fitted with a sub-carrier plate of appropriate thickness to form a carrier unit with a height that matches the length of the suction head to be inserted. The sub-carrier plate acts as a height adjustment component, which can flexibly adjust the height of the carrier unit, so that the combined carrier unit can simultaneously load long suction heads and short suction heads, and suction heads of different lengths can be stacked arbitrarily, which can meet the stacking and loading of various combinations such as long suction heads, short suction heads, and long and short suction heads; 2. Set a limiting post at the bottom of the main carrier plate or the sub-carrier plate to engage with the limiting hole of the lower layer to ensure the stability of the stacked carrier units and ensure that there is no offset between the multi-layer carrier units, so as to facilitate stacking and transplanting.

However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0017] like Figures 1 to 3 As shown, this utility model discloses a stackable carrier for matching long and short suction heads, including a bottom box 1 and a cover 2 that can be fitted together. A set of stacked carrier units is arranged between the bottom box 1 and the cover 2. Each carrier unit includes a main carrier plate 3 and a secondary carrier plate 4. The secondary carrier plate 4 is detachably disposed at the bottom of the main carrier plate 3. A set of first insertion holes 301 is vertically arranged in the main carrier plate 3, and a set of second insertion holes 401 is arranged in the secondary carrier plate 4. The set of first insertion holes 301 and the set of second insertion holes 401 are directly opposite each other, and the inner diameter of the first insertion hole 301 and the second insertion hole 401 is smaller than the outer diameter of the head of the suction head 5 and larger than the outer diameter of the rod of the suction head 5. The head of the suction head 5 is confined between the two carrier units, and the rods of the upper and lower suction heads 5 are not in contact.

[0018] This design features a detachable sub-carrier plate 4 at the bottom of the main carrier plate 3. This allows the main carrier plate 3 to be fitted with a sub-carrier plate 4 of suitable thickness to form a carrier unit whose height matches the length of the insertable nozzle. The sub-carrier plate 4 acts as a height adjuster, allowing for flexible adjustment of the carrier unit's height. This enables the assembled carrier unit to simultaneously accommodate both long nozzles 7 and short nozzles 8. Figure 2 As shown, it can accommodate stacking and loading of various combinations of suction heads, such as long suction heads, short suction heads, and long and short suction heads.

[0019] Specifically, the main carrier plate 3 includes a receiving cavity 302, the first insertion hole 301 is disposed in the upper half of the receiving cavity 302, and the lower half of the receiving cavity 302 extends downward to form a first extension wall 303, which serves as a support.

[0020] The diameters of the long suction head 7 and the short suction head 8 decrease sequentially from top to bottom. Both the long suction head 7 and the short suction head 8 have segmented tube sections, with the inner diameter of each section decreasing sequentially from top to bottom. The length of the first insertion hole 301 is at least not less than the length of the first segment of the long suction head 7's tube diameter to ensure that the long suction head 7 can be inserted into the first insertion hole 301. Preferably, the inner diameter of the first insertion hole 301 gradually decreases from top to bottom to match the tube diameter structure of the long suction head 7 and the short suction head 8, reducing excessive movement of the long suction head 7 and the short suction head 8 within the first insertion hole 301.

[0021] The upper half of the sub-carrier plate 4 extends upward to form a second extension wall 402, and the top opening of the second extension wall 402 forms a latch 403 that matches the bottom of the first extension wall 303, and the latch 403 engages with the bottom of the first extension wall 303. In a preferred embodiment, the latch 403 and the first extension wall 303 are interference-fitted to achieve quick engagement and disengagement between the main carrier plate 3 and the sub-carrier plate 4. In other feasible embodiments, the bottom of the main carrier plate 3 and the opening of the sub-carrier plate 4 can also be connected by any other suitable method or structure for quick disengagement or quick engagement, such as by using matching latches and buckles.

[0022] The inner wall of the second extension wall 402 has a first stepped surface 404. The bottom of the first extension wall 303 abuts against the first stepped surface 404 to limit the maximum engagement distance between the first extension wall 303 and the latch 403, ensuring that the bottom of the first extension wall 303 is not excessively squeezed and damaged, avoiding disassembly difficulties, and ensuring the height consistency of each frame unit composed of the main carrier plate 3 and the auxiliary carrier plate 4.

[0023] The top of the inner wall of the base box 1 forms a third stepped surface 101 that matches the bottom of the sub-carrier plate 4, and the sub-carrier plate 4 is movably engaged within the base box 1. The third stepped surface 101 can limit the position of the sub-carrier plate 4, so that the bottommost carrier unit can be stably engaged within the base box 1 without shaking.

[0024] To further improve the stability of the carrier unit, a limiting groove 102 is provided on the top side of the bottom box 1, and ears 305 are symmetrically provided on both sides of the main carrier plate 3. The bottom of the ears 305 is movably locked in the limiting groove 102.

[0025] The bottom of the sub-carrier plate 4 has a downward-protruding limiting post 405, and the top of the main carrier plate 3 has a limiting hole 306 that matches the limiting post 405. When a group of carrier units are stacked layer by layer, the limiting post 405 is engaged in the limiting hole 306. This structure can ensure the stability of the stacked carrier units and ensure that there is no offset between multiple layers of carrier units, so as to facilitate stacking and relocation.

[0026] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0027] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
