[0002] As a core consumable component of pipettes, pipette tips are widely used in experimental fields such as molecular biology, genetics, and clinical testing. The rationality of the structure of their storage box directly affects the efficiency of experimental operations and the cleanliness and integrity of the pipette tips.

[0003] A search revealed Chinese Patent Publication No. CN221606629U, which discloses a large-capacity pipette tip packaging box, including a top cover, a box body, and a support frame. The support frame is located on top of the box body, and the top cover closes onto the box body. The rear end of the top cover is hinged to the box body, and the front end of the top cover is locked to the box body. The support frame and guide frame of this utility model are detachable from the box body, and the support frame's locking mechanism via locking blocks and slots ensures good stability when installed on the box body.

[0004] Existing pipette tip packaging boxes use a structure where the outer shell and the core are fixedly connected, and can only store pipette tips of a single size. When experiments require changing to pipette tips with different capacities (such as 1000μL, 500μL, 100μL), the entire storage box must be replaced, which not only increases experimental costs but also occupies more laboratory storage space.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a large-capacity pipette tip storage box, which would have greater industrial application value. Utility Model Content

[0043] Guiding and positioning structure: On the front and rear sides of the inner wall of the lower housing 101, a first guide block 105 and a second guide block 106 (both are cuboid protrusions with a length consistent with the width of the inner wall of the housing) are arranged in a stepped manner (the height of the first guide block 105 is higher than that of the second guide block 106, and the difference is equal to the height difference between the upper support edge 107 and the lower support edge 108) to guide the precise installation of the load-bearing components.

[0044] Reinforcement and partitioning structure: The bottom surface and side walls of the lower housing 101 are integrally formed with several protruding ribs 109 to enhance the structural strength of the lower housing 101 and prevent deformation under stress; several partitions 110 can also be detached and installed inside, which are fixed by the slots preset on the inner wall of the lower housing 101, so that the interior of the lower housing 101 can be divided into two or more independent areas to realize the partitioned storage of suction heads of different specifications or uses.

[0045] Top cover protective structure: The top of the top cover 201 is integrally formed with raised edges 204 around the perimeter, which can prevent liquids and dust on the surface of the cover from flowing into the box, and at the same time enhance the deformation resistance of the top cover 201.

[0046] 4. Structural details of upper load-bearing component 3 Upper support assembly 3 is used to store larger pipette tips, including: Upper support plate 301: a rectangular plastic plate, the size of which is adapted to the internal cross-section of the lower box 101.

[0047] The suction head positioning structure is as follows: Several upper through holes 302 (circular, with the hole diameter designed according to the diameter of the top of the suction head) are evenly opened on the upper support plate 301. Each upper through hole 302 has an upper through tube 308 (cylindrical, with the inner diameter consistent with the upper through hole 302) extending vertically downward from the bottom. The suction head can be inserted into the upper through hole 302 from above and pass through the upper through tube 308 to achieve vertical positioning.

[0048] Installation support structure: Several upper support teeth 307 are integrally formed at the four corners and edges of the bottom of the upper support plate 301. The upper support teeth 307 can be stably placed on the upper support edge 107 to ensure that the upper support plate 301 is horizontally fixed.

[0049] The upper support plate 301 has an integrally formed upper clamping plate 304 (a rectangular plate with the same height as the upper support plate 301) on both sides. The upper clamping plate 304 has an upper clamping block 306 on the outer side corresponding to the clamping groove 104. During installation, the upper clamping block 306 can be embedded in the clamping groove 104 to achieve lateral fixation. The upper clamping plate 304 has upper guide grooves 303 (rectangular grooves that fit the first guide block 105) on both the front and rear sides. During installation, the first guide block 105 is embedded in the upper guide groove 303 to guide the upper support component 3 to accurately fall on the upper support edge 107.

[0050] Auxiliary reinforcement structure: On the outer side of the upper plate 304, above the upper block 306, there are several upper contact protrusions 305 (hemispherical) integrally formed. When the upper cover plate 201 is closed, the upper contact protrusions 305 are in close contact with the inner side of the upper cover plate 201, further limiting the longitudinal sway of the upper load-bearing component 3.

[0051] 5. Structural details of the lower load-bearing component 4 The lower support assembly 4 is used to store smaller pipette tips, including: Lower support plate 401: a rectangular plastic plate, the size of which is adapted to the internal cross-section of the lower box 101.

[0052] The suction head positioning structure is as follows: Several lower through holes 402 (circular, with the hole diameter designed according to the top diameter of the small-sized suction head) are evenly opened on the lower support plate 401. A lower through tube (cylindrical, with the inner diameter consistent with the lower through hole 402) extends vertically downward from the bottom of each lower through hole 402 to achieve vertical positioning of the small-sized suction head.

[0053] Installation support structure: The bottom of the lower support plate 401 is placed directly on the lower support edge 108, and anti-slip protrusions can be provided on the bottom edge to enhance the stability of placement.

[0054] Snap-fit ​​and guide structure: The lower support plate 401 has an integrally formed lower snap-fit ​​plate 404 (rectangular plate with the same height as the lower support plate 401) on both sides. The lower snap-fit ​​plate 404 has a lower snap-fit ​​block 407 on the outer side corresponding to the snap-fit ​​groove 104. During installation, the lower snap-fit ​​block 407 can be embedded in the snap-fit ​​groove 104. The lower snap-fit ​​plate 404 has a lower guide groove 403 (rectangular groove that matches the second guide block 106) on both the front and rear sides. During installation, the second guide block 106 is embedded in the lower guide groove 403 to guide the lower support component 4 to fall accurately on the lower support edge 108.

[0055] Auxiliary reinforcement and linkage structure: On the outer side of the lower clamping plate 404, above the lower clamping block 407, there are several lower contact protrusions 406 (hemispherical), which have the same function as the upper contact protrusions 305; On the inner side of the lower clamping plate 404, there are also several lower rib blocks 405 (cubic protrusions), which are integrally formed. When the upper and lower load-bearing components are installed at the same time, the inner side of the upper clamping plate 304 can make close contact with the lower rib blocks 405 to form upper and lower linkage reinforcement, further improving the overall installation firmness.

[0056] During operation, simply flip the top cover 201 upwards (without disassembling the support assembly) to directly access the suction head from above. After use, close the top cover 201, which is sealed by the snap fasteners to prevent contamination of the suction head. If the suction head specification needs to be changed, pull the upper support plate 301 upwards (to disengage the upper locking block 306 from the locking slot 104), and remove the upper support assembly 3 along the first guide block 105 to replace it with other compatible components (such as the lower support plate 401).
