Description

Technical Field

[0001] This utility model relates to the field of scientific research equipment technology, and more specifically, to a rotary multifunctional pipette tip collection device. Background Technology

[0002] Because pipettes can precisely control the amount of liquid used, they are widely used in scientific research experiments in medicine, chemistry and environment. Currently, there are many sizes of pipettes in use, such as 2-20ul, 10-100ul, 10-200ul, 100-1000ul, 1000-5000ul, etc., and there are also many sizes of matching pipette tips. However, commercially available pipette tip boxes can only hold pipette tips of the same size. In experiments, multiple different sizes of pipette tips may be used at the same time. Although ordinary pipette tip boxes can effectively organize various sizes of pipette tips, single-size boxes need to be placed on the lab bench and different sizes of boxes need to be opened each time they are used, which occupies extra lab bench space and increases unnecessary experimental time.

[0003] A search revealed that Chinese patent CN216987761U discloses a rotary multifunctional pipette tip collection device. This structure is easy to operate, effectively reduces the space occupied on the experimental bench, is convenient to use, and saves experimental time.

[0004] However, in actual use, this structure only contacts the test bench through a rubber base to support the entire device, which is not very effective. Once the device is rotated and unfolded during use, it is easy for it to tip over if it is hit or shaken by the test bench, which will contaminate the pipette tips inside the device and affect its use. In view of this, this utility model proposes a rotary multifunctional pipette tip collection device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotary multifunctional pipette tip collection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary multifunctional pipette tip storage device, comprising a base, a support plate on the top of the base, and a support seat on the top of the support plate. From top to bottom, the surface of the support seat is provided with a first pipette tip box, a second pipette tip box, and a third pipette tip box for storing pipette tips of different specifications. The first, second, and third pipette tip boxes are connected by a rotating shaft, allowing the first, second, and third pipette tip boxes to communicate with each other. The pipette tips are rotated out for use. The rotating shaft is fixed on the support base. The first pipette tip box is provided with a top cover. The surface of the second pipette tip box is covered by the bottom of the first pipette tip box. The surface of the third pipette tip box is covered by the bottom of the second pipette tip box. A bottom plate is provided under the third pipette tip box. The first, second, and third pipette tip boxes and the top cover are all made of polyethylene. A sealing gasket is provided on the top cover, the bottom of the first pipette tip box, and the bottom of the second pipette tip box to enhance the sealing.

[0007] As can be seen, the three-layer nozzle box, connected by a rotating shaft, is used to store nozzles of different specifications. The nozzles are distinguished by the color of the partitions, and are accessed by rotating. All components are made of polyethylene, and a sealing gasket at the bottom enhances sealing, making it convenient to use. To improve the stability of the device during use and prevent tipping, preferably, the bottom of the base is provided with a fixing structure, which includes an L-shaped plate. The L-shaped plate is fixedly installed at the bottom of the base, and a clamping plate is slidably installed inside the L-shaped plate. The surface of the clamping plate is provided with a rubber pad. An adjusting screw is connected to the center of the bottom of the clamping plate. Guide rods are provided on both sides of the adjusting screw. The adjusting screw is threadedly connected to the L-shaped plate, and one end of each guide rod is fixedly connected to the clamping plate and slidably connected to the L-shaped plate.

[0008] To facilitate the adjustment of the height of the three-layer gun head box for easy operation, preferably, two lead screws are fixedly installed between the base and the support plate, and a connecting plate is slidably installed on the outside of the two lead screws. A connecting rod is fixedly installed at the center of the surface of the connecting plate, and the connecting rod is slidably connected at the center of the surface of the support plate. The top end of the connecting rod is fixedly connected to the support seat. A limit nut is provided on the outside of the two lead screws and at the bottom of the connecting plate. The limit nut is threadedly connected to the corresponding lead screw.

[0009] The technical effects and advantages of this utility model are as follows: By setting up a fixed structure and using an adjusting screw to drive the clamping plate and rubber pad to clamp the experimental platform, the stability of the device is greatly enhanced, effectively preventing the device from tipping over due to collisions or shaking of the experimental platform, preventing the pipette tip from being contaminated, providing a safe and reliable pipette tip storage environment for experimental operations, and ensuring the smooth progress of the experiment. The overall height of the device can be flexibly adjusted according to the operating height requirements of the experimenter by using the connecting plate to adjust the height of the two lead screws. This makes the device more user-friendly. At the same time, the connecting plate is fixed with the limit nut after adjustment to ensure that the device maintains a stable height during use, thus improving the convenience and comfort of experimental operation.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As attached Figure 1-4The rotary multifunctional pipette tip storage device shown includes a base 1, a support plate 2 on top of the base 1, and a support seat 3 on top of the support plate 2. From top to bottom, the surface of the support seat 3 is provided with a first pipette tip holder 4, a second pipette tip holder 5, and a third pipette tip holder 6 for storing pipette tips of different sizes. The first pipette tip holder 4, the second pipette tip holder 5, and the third pipette tip holder 6 are connected by a rotating shaft 7, allowing the first pipette tip holder 4, the second pipette tip holder 5, and the third pipette tip holder 6 to be rotated out separately. In use, the rotating shaft 7 is fixed on the support base 3. The first pipette tip box 4 is provided with a top cover 8. The surface of the second pipette tip box 5 is covered by the bottom of the first pipette tip box 4. The surface of the third pipette tip box 6 is covered by the bottom of the second pipette tip box 5. A base plate 9 is provided under the third pipette tip box 6. The first pipette tip box 4, the second pipette tip box 5, the third pipette tip box 6 and the top cover 8 are all made of polyethylene. A sealing gasket is provided at the bottom of the top cover 8, the first pipette tip box 4 and the second pipette tip box 5 to enhance the sealing.

[0017] Specifically, in this structure, the first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 can store pipette tips of different sizes. The first type is used to store 20ul, 200ul, and 1000ul pipette tips, respectively. The second type is used to store 20ul, 1000ul, and 5ml pipette tips, respectively. The third type is used to store 200ul, 1000ul, and 5ml pipette tips, respectively. The rotating shaft 7 is fixed on the support base 3, and the first pipette tip box 4, the second pipette tip box 5 and the third pipette tip box 6 are connected by the rotating shaft 7, and can be rotated out for use, making it convenient to pick up pipette tips of different specifications. The first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 are all colorless and transparent. The dividers within each pipette tip box are different colors to distinguish the different sizes of pipette tips they hold; for example, white for 20µl tips, yellow for 200µl tips, and blue for 1000µl tips. To use, simply rotate the desired size pipette tip box left or right to open it. The rotation is shown in the attached diagram. Figure 2 As shown.

[0018] This structure is disclosed in the prior art CN216987761U and is not considered an improvement of this application, so it will not be described in detail.

[0019] The improvements in this application are as follows: In this embodiment, as shown in the appendix Figure 1 , 4 As shown, a fixing structure is provided at the bottom of the base 1. The fixing structure includes an L-shaped plate 10, which is fixedly installed at the bottom of the base 1. A clamping plate 11 is slidably installed inside the L-shaped plate 10, and a rubber pad 12 is provided on the surface of the clamping plate 11. An adjusting screw 13 is connected to the center of the bottom of the clamping plate 11. Guide rods 14 are provided on both sides of the adjusting screw 13. The adjusting screw 13 is threadedly connected to the L-shaped plate 10. One end of each guide rod 14 is fixedly connected to the clamping plate 11, and the guide rods 14 are slidably connected to the L-shaped plate 10.

[0020] Specifically, in this structure, to improve the stability of the storage device placed on the test bench and prevent it from shaking or tipping over due to collisions, the operator aligns the clamping plate 11 with the edge of the test bench and moves the clamping plate 11 closer to the test bench by rotating the adjusting screw 13. The clamping plate 11 is guided by two guide rods 14. At this time, the test bench is clamped between the rubber pad 12 on the surface of the clamping plate 11 and the base 1, thus providing stable clamping for the device. The rubber pad 12 can improve the stability of the clamping. Regardless of whether the first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 collide during rotation and unfolding, or whether the test bench shakes due to a collision, the stability of the device placement can be guaranteed, preventing tipping and contamination of the pipette tips during use.

[0021] In this embodiment, as shown in the appendix Figure 1 , 3 As shown, two lead screws 15 are fixedly installed between the base 1 and the support plate 2, and a connecting plate 16 is slidably installed on the outside of the two lead screws 15. A connecting rod 17 is fixedly installed at the center of the surface of the connecting plate 16. The connecting rod 17 is slidably connected at the center of the surface of the support plate 2, and the top of the connecting rod 17 is fixedly connected to the support base 3. A limit nut 18 is provided on the outside of the two lead screws 15 and at the bottom of the connecting plate 16. The limit nut 18 is threadedly connected to the corresponding lead screw 15.

[0022] Specifically, in this structure, after the device is clamped and fixed in the designated position on the test bench by the fixing structure, the operator can adjust the connecting plate 16 by sliding it up and down according to their own height. This allows the connecting plate 16 to slide outside the two lead screws 15. The connecting plate 16 slides on the support plate 2 through the connecting rod 17, which drives the support base 3 to adjust up and down. This, in turn, drives the first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 to move, thereby adjusting the usage height of the device and making it convenient for the operator to use. After the connecting plate 16 is slidably adjusted, the corresponding limiting nut 18 is rotated so that the limiting nut 18 rotates on the external thread of the corresponding lead screw 15. The limiting nut 18 is rotated and adjusted to the bottom of the connecting plate 16 to limit the connecting plate 16 and prevent the connecting plate 16 from slipping downward.

[0023] Working principle of this utility model: This application provides a rotary multifunctional pipette tip storage device. In actual use, before using the device, the experimenter first places it in a suitable position on the experimental table according to the actual situation. At this time, the clamping plate 11 in the bottom fixing structure of the base 1 is aligned with the edge of the experimental table, and the adjusting screw 13 is turned. Since the adjusting screw 13 is threadedly connected to the L-shaped plate 10, as the adjusting screw 13 rotates, the clamping plate 11 moves closer to the experimental table under the sliding guidance of the guide rod 14. Finally, the experimental table is firmly clamped between the rubber pad 12 on the surface of the clamping plate 11 and the base 1. The rubber pad 12 increases the friction and improves the clamping stability, ensuring that the device will not tip over due to collision or shaking during subsequent use, and providing a safe storage environment for the pipette tips. After the device is fixed, the experimenter adjusts the height of the device according to their own operating height requirements. By sliding the connecting plate 16 up and down, it moves outside the two lead screws 15. Because the connecting rod 17, which is fixedly installed at the center of the surface of the connecting plate 16, slides at the center of the surface of the support plate 2, and the top of the connecting rod 17 is fixed to the support base 3, the sliding of the connecting plate 16 drives the support base 3 to move up and down, thereby driving the first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 to move synchronously. After adjusting to a suitable height, the limiting nut 18 is rotated so that it rotates on the thread outside the lead screw 15 and is tightly attached to the bottom of the connecting plate 16, limiting the connecting plate 16 and preventing it from sliding down, ensuring that the device is stably at the adjusted height. After the device is fixed and the height is adjusted, the pipette tip retrieval process begins. When the experimenter needs a pipette tip of a certain size, the corresponding pipette tip box is rotated to the left or right. Since the first pipette tip box 4, the second pipette tip box 5, and the third pipette tip box 6 are connected to the support base 3 via the rotating shaft 7, the pipette tip boxes rotate out around the rotating shaft 7 during the rotation. Each pipette tip box is colorless and transparent, and the partitions inside that hold the pipette tips are distinguished by different colors to facilitate quick identification by the experimenter. After opening the pipette tip box, the required pipette tip can be retrieved for experimental operation.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
