Description

Technical Field

[0001] This utility model relates to the field of pipettes, and in particular to a self-regulating pipette tip storage device. Background Technology

[0002] A pipette is a precision liquid-taking instrument commonly used in biological, chemical, and medical laboratories. By adjusting the movement distance of the internal piston, the volume of liquid aspirated and expelled can be precisely controlled, allowing a certain amount of liquid to be transferred from one container to another. It can accurately measure and transfer trace or small amounts of liquid within a set range. Pipettes are characterized by ease of operation, high pipetting accuracy, and good repeatability. However, the storage of pipette tips should follow the principles of convenient access, prevention of contamination, and classified storage.

[0003] Currently, users often use tweezers to store pipette tips in the storage box. Using tweezers can avoid direct contact between fingers and pipette tips, reducing the possibility of contamination. However, experiments require a large number of pipette tips, which leads to the problem of inefficiency and large error when using tweezers to store pipette tips. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a self-regulating pipette tip storage device, which aims to improve the problem of inefficiency and large error in using tweezers to store and retrieve pipette tips due to the large number of pipette tips required for experiments.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A self-regulating pipette tip storage device includes a feed box, a discharge plate on the lower surface of the feed box, a storage box on the lower surface of the discharge plate, a suction block on the inner wall of the feed box, a sliding component on the outer wall of the suction block, the sliding component being connected to the inner wall of the feed box, a gripping component on the outer wall of the suction block, a feed groove inside the suction block, a storage groove inside the storage box, a fixing post fixedly connected to the side wall of the discharge plate, a rotating ring rotatably connected to the outer wall of the fixing post, a limiting component on the outer wall of the rotating ring, and the limiting component being connected to the side wall of the storage box.

[0007] Preferably, the sliding assembly includes a slider, the outer wall of which is fixedly connected to the outer wall of the material extraction block, and a sliding groove is provided inside the material handling box, through which the slider is slidably connected to the inner wall of the material handling box.

[0008] Preferably, the gripping assembly includes a handle, the outer wall of which is fixedly connected to the outer wall of the material extraction block, and a gripping groove is formed inside the handle.

[0009] Preferably, the limiting component includes a connecting rod, the top end of which is fixedly connected to the outer wall of the rotating ring, and the bottom end of which is fixedly connected to a locking block. The storage box has a locking groove inside, and the outer wall of the locking block is set inside the storage box through the locking groove.

[0010] Preferably, the discharge plate has a discharge groove inside.

[0011] Preferably, a fixing block 1 is fixedly connected to the outer wall of the material feeding box, a turntable 1 is rotatably connected inside the fixing block 1, a handle 2 is fixedly connected to the outer wall of the turntable 1, a fixing block 2 is fixedly connected to the outer wall of the material feeding block, and a turntable 2 is rotatably connected to the inner wall of the fixing block 2.

[0012] Preferably, the inside of the fixing block one is provided with a sliding groove two, and the outer wall of the handle two is disposed inside the sliding groove two.

[0013] Preferably, the lower surface of the first fixing block is disposed on the upper surface of the second fixing block, and the upper surface of the second turntable is disposed on the lower surface of the first turntable.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by placing the pipette tips in the feeding box, then tilting and shaking the feeding box, the pipette tips are vertically distributed inside the feeding trough. Then, the feeding box is moved to the right opening of the discharge plate and then moved to the left. The left side of the discharge trough has holes and slots evenly distributed for the pipette tips, corresponding to the storage slots. The pipette tips are moved to the left and evenly distributed in the holes and slots. When the extraction block is pulled, since one end of the extraction block is open and not closed, the extraction block leaves the arranged pipette tips one by one, and then the pipette tips fall from the discharge trough into the storage slot. This achieves the effect of accurately and quickly storing multiple pipette tips in a single operation.

[0016] 2. In this utility model, by pulling the second handle to rotate the second handle, the first turntable rotates under the drive of the second handle, and then the second turntable rotates under the drive of the first turntable. At this time, the first turntable is simultaneously locked into the first and second fixing blocks, and the second turntable is also simultaneously locked into the first and second fixing blocks, thereby achieving the effect of preventing the material extraction block from accidentally slipping out and causing the pipette tip to scatter and be contaminated.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a self-regulating pipette tip storage device, including a material handling box 1, a discharge plate 2 on the lower surface of the material handling box 1, a storage box 3 on the lower surface of the discharge plate 2, a material extraction block 4 on the inner wall of the material handling box 1, a sliding component on the outer wall of the material extraction block 4, the sliding component being connected to the inner wall of the material handling box 1, a gripping component on the outer wall of the material extraction block 4, a material handling groove 9 inside the material extraction block 4, a storage groove 10 inside the storage box 3, a fixing post 17 fixedly connected to the side wall of the discharge plate 2, a rotating ring 18 rotatably connected to the outer wall of the fixing post 17, a limiting component on the outer wall of the rotating ring 18, and the limiting component being connected to the side wall of the storage box 3.

[0026] Specifically, firstly, a plurality of pipette tips are placed inside the feed hopper 1. Then, the feed hopper 1 is tilted and shaken, causing the pipette tips to roll on the surface of the feed block 4 and slide down the feed groove 9, thus becoming vertically distributed inside the feed groove 9. Next, the feed hopper 1 is moved to the right opening of the discharge plate 2, aligning the lower side of the pipette tips with the discharge groove 19 inside the connecting rod 20. Then, the feed hopper 1 is moved to the left. The left side of the discharge groove 19 has evenly distributed slots corresponding to the receiving groove 10 for the pipette tips. As the feed hopper 1 moves to the left, the pipette tips are evenly distributed in the slots. The discharge plate 2 is fixed at a designated position above the receiving box 3 by a limiting component. The component is used to ensure that the pipette tip is accurately aligned with the storage tank 10. Then, by holding the component and pulling the extraction block 4, the extraction block 4 is moved along the inner wall of the feed box 1 under the action of the sliding component. The pulling component makes it convenient for the user to move the extraction block 4 and saves effort, while the sliding component prevents the displacement of the extraction block 4 from deviating and causing the pipette tip to fail to fall into the storage tank 10. Since one end of the extraction block 4 is open and not closed, the extraction block 4 leaves the arranged pipette tips in sequence and no longer restricts the pipette tips from falling. Then, the pipette tips fall from the discharge tank 19 into the storage tank 10, thereby achieving the effect of accurate and fast storage of multiple pipette tips in a single operation.

[0027] Reference Figure 3 The sliding component includes a slider 5, the outer wall of which is fixedly connected to the outer wall of the material extraction block 4. The inside of the material handling box 1 is provided with a sliding groove 6, and the slider 5 is slidably connected to the inner wall of the material handling box 1 through the sliding groove 6.

[0028] Specifically, since the slider 5 is fixedly connected to the material extraction block 4, the slider 5 slides along the inner wall of the material handling box 1 through the slide groove 6 under the drive of the material extraction block 4.

[0029] Reference Figure 3 The grip assembly includes a grip 7, the outer wall of which is fixedly connected to the outer wall of the material extraction block 4, and a grip groove 8 is provided inside the grip 7.

[0030] Specifically, the grip groove 8 allows the user to hold the handle 7, making it easier for the user to pull the material block 4 and saving effort.

[0031] Reference Figure 2 The limiting component includes a connecting rod 20, the top end of which is fixedly connected to the outer wall of the rotating ring 18, and a locking block 21 is fixedly connected to the bottom end of the connecting rod 20. A slot 22 is provided inside the storage box 3, and the outer wall of the locking block 21 is set inside the storage box 3 through the slot 22. A discharge trough 19 is provided inside the discharge plate 2.

[0032] Specifically, when the locking block 21 is moved, the connecting rod 20 rotates under the drive of the locking block 21 because it is fixedly connected to the connecting rod 20. The rotating ring 18 rotates along the outer wall of the fixed column 17 under the drive of the connecting rod 20 because it is fixedly connected to the connecting rod 20. Then, the connecting rod 20 is fixed inside the storage box 3 through the slot 22.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the feeding box 1 is fixedly connected to a fixing block 11, the inside of the fixing block 11 is rotatably connected to a turntable 12, the outer wall of the turntable 12 is fixedly connected to a handle 13, the outer wall of the feeding block 4 is fixedly connected to a fixing block 15, the inner wall of the fixing block 15 is rotatably connected to a turntable 16; the inside of the fixing block 11 is provided with a sliding groove 14, the outer wall of the handle 13 is located inside the sliding groove 14; the lower surface of the fixing block 11 is located on the upper surface of the fixing block 15, and the upper surface of the turntable 16 is located on the lower surface of the turntable 12.

[0034] Specifically, by pulling the second handle 13, it rotates along the second slide groove 14. Since the first turntable 12 is fixedly connected to the second handle 13, the first turntable 12 rotates along the inner wall of the first fixed block 11 under the drive of the second handle 13. Then, the second turntable 16 rotates along the inner wall of the second fixed block 15 under the drive of the first turntable 12. At this time, the first turntable 12 and the second turntable 16 rotate 90 degrees synchronously. Immediately afterward, the first turntable 12 simultaneously engages with the first fixed block 11 and the second fixed block 15, and the second turntable 16 also simultaneously... Insert the material into the fixing block 11 and fixing block 2 15, thereby connecting the material feeding box 1 and the material extraction block 4 to ensure that the material extraction block 4 will not slip out and cause the pipette tip to scatter when the material feeding box 1 is shaken. When the pipette tip is positioned and aligned with the receiving slot 10, rotate the handle 2 13 in the opposite direction to restore the turntable 1 12 and turntable 2 16 to their original positions. At this time, the material feeding box 1 and the material extraction block 4 are no longer connected, and the material extraction block 4 can be extracted, thereby achieving the effect of preventing the pipette tip from scattering and being contaminated due to the material extraction block 4 accidentally slipping out.

[0035] Working principle: By placing the pipette tip in the feed box 1 and then tilting and shaking the feed box 1, the pipette tip is vertically distributed inside the feed trough 9. Then, the feed box 1 is moved to the right opening of the discharge plate 2 and then moved to the left. The left side of the discharge trough 19 has evenly distributed holes and slots corresponding to the receiving slots 10 for the pipette tips. The pipette tips are moved to the left and evenly distributed in the holes and slots. When the locking block 21 is moved, the connecting rod 20 rotates under the action of the locking block 21. The rotating ring 18 rotates along the outer wall of the fixed column 17 under the action of the connecting rod 20. Then, the connecting rod 20 is fixed inside the storage box 3 through the slot 22. At this time, the discharge plate 2 is fixed at the designated position above the storage box 3. Then, the handle 7 is held by the grip slot 8 to pull the material extraction block 4. The material extraction block 4 moves along the inner wall of the material box 1. Since one end of the material extraction block 4 is open and not closed, the material extraction block 4 leaves the arranged pipette tips in sequence and no longer restricts the pipette tips from falling. Then, the pipette tips fall from the discharge groove 19 into the storage groove 10, thereby achieving the effect of accurately and quickly storing multiple pipette tips at once.

[0036] By pulling the second handle 13, the second handle 13 is rotated, and the first turntable 12 rotates under the drive of the second handle 13. Then the second turntable 16 rotates under the drive of the first turntable 12. At this time, the first turntable 12 is simultaneously locked into the first fixing block 11 and the second fixing block 15, and the second turntable 16 is also simultaneously locked into the first fixing block 11 and the second fixing block 15. Thus, the feed box 1 is connected to the extraction block 4 to ensure that the extraction block 4 will not slip out when the feed box 1 is shaken, causing the pipette tip to scatter. This can achieve the effect of avoiding the pipette tip from scattering and being contaminated due to the extraction block 4 accidentally slipping out.
