Description

Technical Field

[0001] The utility model relates to the technical field of storage boxes, in particular to a multifunctional pipette tip storage box. Background Art

[0002] A pipette tip is a commonly used small tool in laboratories. It is usually made of plastic and is in the shape of a slender tube. In experimental operations, the pipette tip is used in conjunction with a pipettor to accurately aspirate and dispense a certain volume of liquid. It is finely designed with different specifications and capacities to meet the requirements of different liquid volumes for various experiments. The pipette tip can ensure the accurate transfer of liquid, reduce errors, and avoid cross-contamination, thus ensuring the accuracy and reliability of experimental results. Whether in laboratories in the fields of chemistry, biology, medicine, etc., the pipette tip is an indispensable and important tool.

[0003] Currently, in the work of outdoor sample collection, pipette tips and pipettors are often used. However, the pipette tip equipment used in laboratories has many inconveniences. On the one hand, its volume is relatively large and it is not convenient to carry; on the other hand, after opening the pipette tip box, it is very easy to contaminate other pipette tips to be used. In addition, the waste pipette tips after use cannot be discarded randomly and need to be collected for unified treatment. In this way, when collecting samples outdoors, a lot of equipment needs to be carried, which undoubtedly brings greater trouble to the staff, reduces work efficiency, and increases the work burden. Content of the Utility Model

[0004] In order to solve the above various problems, the utility model proposes a multifunctional pipette tip storage box that integrates the functions of preventing contamination of pipette tips to be used, carrying pipette tips, and collecting waste.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a multifunctional pipette tip storage box, including a box body. A partition plate is connected and arranged in the middle of the box body. Sliding grooves are arranged at the upper ends of the front and rear sides inside the box body. A sliding cover plate is slidably arranged in the sliding grooves. A fixed-distance structure for controlling the sliding amount of the sliding cover plate is arranged between the sliding cover plate and the sliding grooves. A perforated box is placed on one side of the partition plate. Circular holes for placing pipette tips are arranged on the perforated box. There are several columns of the circular holes. A waste storage box is placed on the other side of the partition plate. A waste inlet structure for cooperating with the waste storage box is arranged at the upper end of the front surface of the box body; a storage bag adapted to the box body is also equipped.

[0006] Further, the distance - determining structure includes cylinders connected to the upper ends of the front and rear sides of the box body. A circular plate is slidably arranged inside the cylinder. A return spring is connected between the circular plate and the bottom of the cylinder. A round bead is connected to one side surface of the circular plate away from the return spring. Bead grooves adapted to the round beads are equidistantly arranged on the front and rear sides of the sliding cover plate. The combination of the cylinder, circular plate, return spring, and round bead in the distance - determining structure can effectively control the sliding - out amount of the sliding cover plate, ensuring that the position of the sliding cover plate can be accurately positioned during use, which is convenient for the user to operate. When the round bead is stuck in the bead groove, the sliding cover plate can be stably fixed to prevent accidental sliding.

[0007] Further, the distance between the bead grooves is equal to the distance between the several columns of round holes. The equal distance between the bead grooves and the several columns of round holes enables the sliding distance of the sliding cover plate each time to correspond to the column pitch of the round holes. In this way, during use, the opening degree of the sliding cover plate can be more accurately controlled, which is convenient for the user to pick up pipette tips in different columns.

[0008] Further, square holes for the sliding cover plate to slide out are connected to the upper ends of both sides of the box body. The square holes at the upper ends of both sides of the box body allow the sliding cover plate to slide out, ensuring the smooth sliding of the sliding cover plate without jamming due to the structural limitations of the box body. At the same time, the square holes also provide a larger space for the operation of the sliding cover plate, facilitating the user's pushing and pulling operations.

[0009] Further, the waste - inlet and - outlet structure includes a sliding hole connected to the upper end of the front surface of the box body. An inlet box is slidably arranged inside the sliding hole. An inlet ramp inclined towards the waste - containing box is arranged inside the inlet box. The design of the sliding hole and the inlet box in the waste - inlet and - outlet structure enables waste to enter the waste - containing box conveniently. The setting of the inlet ramp can guide the waste to smoothly slide into the waste - containing box, avoiding waste accumulation in the inlet box.

[0010] Further, a slot is arranged outside the sliding hole. An insertion plate that can be inserted into the slot is connected to the outside of the inlet box. The cooperation between the slot outside the sliding hole and the insertion plate outside the inlet box can ensure the stability of the inlet box during storage, preventing the accidental detachment of the inlet box. At the same time, this embedded design also makes the whole structure more compact, beautiful and generous.

[0011] Further, a lifting handle is provided at the upper ends of the front and rear sides of the storage bag. Upper fixing straps fixed by Velcro are connected to both sides of the lifting handle. Holes for accommodating the cylinders are provided on both the front and rear sides of the storage bag. The lifting handle at the upper ends of the front and rear sides of the storage bag facilitates the user to carry the entire storage box. The upper fixing straps are fixed by Velcro, which can effectively fix the storage box in the storage bag and prevent it from shaking during carrying. The holes on the front and rear sides of the storage bag can accommodate the cylinders, making the structure of the entire storage bag more reasonable and convenient for storage and carrying.

[0012] Further, a push-pull handle is connected to one side of the sliding cover plate. This provides convenience for the user to operate the sliding cover plate, enabling the user to open and close the sliding cover plate more easily.

[0013] The advantages of the present utility model compared with the prior art are as follows:

[0014] First, in terms of preventing contamination of the pipette tips to be used, the storage box is provided with a sliding cover plate. The sliding is ensured smoothly through the square holes on both sides of the box body, which is convenient for operation and can provide good protection for the pipette tips at the same time. The fixed-distance structure between the sliding cover plate and the sliding groove, including a cylinder, a round plate, a return spring, a round bead, and a bead groove adapted to the round bead, can accurately control the position of the sliding cover plate to ensure that the pipette tips are tightly covered when not in use, effectively preventing external contaminants from entering the perforated box and contacting the pipette tips to be used. At the same time, the distance between the bead grooves is equal to the distance between the rows of round holes, so that each time the sliding cover plate is opened, it can accurately correspond to a specific row of pipette tips, reducing unnecessary exposure and further reducing the risk of contamination.

[0015] Second, it performs excellently in carrying the pipette tips and collecting waste. The storage box is equipped with a matching storage bag. The lifting handles at the upper ends of the front and rear sides of the storage bag facilitate the user to carry the entire storage box. The upper fixing straps are fixed by Velcro, which can effectively prevent the storage box from shaking during carrying and ensure the safety of the pipette tips during movement. The holes on the front and rear sides of the storage bag can accommodate the cylinders, making the structure more reasonable and convenient for storage and carrying. For the waste after use, the box body is provided with a waste inlet structure, including a sliding hole, an inlet box, and a feeding ramp inside the inlet box, which can conveniently guide the waste to the waste storage box, avoiding waste accumulation in other places and causing pollution. The panel on the outside of the inlet box and the slot on the outside of the sliding hole cooperate with each other to ensure the stability of the inlet box during storage and prevent accidental detachment, so that the entire storage box can safely collect waste during carrying, providing great convenience for experimental operations.
