Description

Technical Field

[0001] This utility model relates to the field of suction head technology, specifically to a stacked suction head release structure. Background Technology

[0002] In experiments conducted in fields such as molecular biology and clinical diagnostics, pipette tips (or simply pipette tips) are disposable laboratory equipment. To facilitate storage and automated retrieval, pipette tips are mass-produced and inserted into slots in plate holders, forming... Figure 1 The suction head holder 200 shown is mounted on, for example, Figure 2 The nozzle box shown is 100. Typically, one nozzle box is needed for each nozzle tray, resulting in wasted nozzle boxes.

[0003] To reduce waste, a stackable suction head design has been developed. This involves stacking multiple suction head racks inside a hollow, rectangular, transparent housing. The interior of the housing has protrusions corresponding to each layer of suction head racks, which are used to support the suction head racks.

[0004] When replenishing the nozzle tray with nozzles, the user first places the transparent shell on top of the nozzle tray, making the inner cavity of the transparent shell connected to the inner cavity of the nozzle tray. Then, the user presses down on the stacked nozzles, causing them to move down one layer (the distance between two adjacent nozzle trays) to overcome the resistance of the protrusions, releasing the bottom nozzle tray into the nozzle tray. The above operation can be repeated whenever the nozzle tray in the nozzle tray is used up, enabling the nozzle tray to be reused and reducing waste.

[0005] However, the above method of manually pressing the stacked suction head to convey it downwards has the following drawbacks: First, when manually pressing the stacked suction heads, users have difficulty controlling the amount of force applied. They may apply too much force, causing the other suction head frames above them to be pressed and released together when the bottom suction head frame is released, which reduces the accuracy of the release.

[0006] Secondly, when users manually press the stacked suction head, they need to apply force from top to bottom, which puts the user in a position looking down at the stacked suction head. It is difficult for the user to observe from the side of the transparent shell whether it is released accurately, which also reduces the release accuracy. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a stacked suction head release structure. This invention can prevent the suction head plate from being pulled along during downward conveying, facilitates observation, and improves release accuracy.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stacked suction head release structure includes a suction head box, a suction head frame, and a transparent shell. The transparent shell is placed on top of the suction head box. Multiple suction head frames are stacked vertically inside the transparent shell. A transmission belt assembly and a limiting structure are provided on both the left and right sides of the transparent shell. The transmission belt assembly includes an upper roller and a lower roller rotatably connected to the transparent shell. The upper roller and the lower roller are driven by a transmission belt. Multiple partition plates are provided around the transmission belt. The partition plate on the side of the transmission belt facing the suction head frame is used to support the suction head frame. The partition plate on the side of the transmission belt away from the suction head frame abuts against the bottom of the limiting structure.

[0009] Furthermore, both lower rollers are provided with rocker handles at their ends.

[0010] Furthermore, both lower rollers are equipped with synchronous pulleys at their ends, and the two synchronous pulleys are connected by a figure-eight synchronous belt.

[0011] Furthermore, the transparent housing is provided with a top cover.

[0012] Furthermore, the limiting structure includes a limiting pin, an elastic element, and a fixing seat. The limiting pin is horizontally slidably connected to the transparent housing along the direction of entering and exiting the transparent housing. One end of the limiting pin located inside the transparent housing has a spherical surface, and the bottom of the spherical surface abuts against the partition plate. The fixing seat is located on the outer wall of the transparent housing. The limiting pin is connected to the fixing seat through the elastic element, which is used to push the limiting pin to slide into the transparent housing.

[0013] Furthermore, the limiting pin has a limiting ring and a receiving cavity at one end located outside the transparent shell. The limiting ring is used to prevent the limiting pin from completely entering the transparent shell, and the elastic element is located in the receiving cavity.

[0014] Furthermore, the transparent shell is provided with expansion boxes on both the left and right sides, the inner cavity of the expansion box is connected to the inner cavity of the transparent shell, the upper roller and the lower roller are rotatably connected to the side wall of the expansion box, and the limiting structure is provided on the side wall of the expansion box.

[0015] The beneficial effects of this utility model are: 1. Each suction head holder stacked inside the transparent housing is supported and separated by partition plates. Rotating the transmission belt allows the partition plates on the inner side of the belt to smoothly support and downwardly transport the suction head holder. On one hand, this invention changes the press-release method in the prior art to a rotation-release method, avoiding chain reactions due to excessive user pressure and improving release accuracy. On the other hand, when the user rotates to release the suction head holder, they rotate the transmission belt from the side of the transparent housing, allowing the user to easily observe whether the suction head holder has been accurately released from the side of the transparent housing, which also helps improve release accuracy.

[0016] 2. By setting limiting structures on the left and right sides of the transparent housing to work in conjunction with the transmission belt assembly, the partition plate on the outside of the transmission belt can cyclically abut against the bottom of the limiting structure. When there is no external force driving the transmission belt to run, the limiting structure can limit the partition plate and prevent the transmission belt from running. This can prevent the suction head plate frame inside the transparent housing from being accidentally released from the bottom of the transparent housing, thus improving the reliability of use.

[0017] 3. By setting a crank handle at the end of the lower roller, a clear and convenient manual operation interface is provided for the user, making the release action easy to control and execute.

[0018] 4. By setting synchronous pulleys connected by figure-eight synchronous belts at the ends of the two lower rollers, it is ensured that the transmission belt assemblies on the left and right sides can operate in precise and synchronous manner, avoiding the risk of the suction head plate being jammed or damaged due to asynchrony between the two sides, and further improving the reliability and stability of use.

[0019] Furthermore, the user only needs one hand to operate one crank, which can drive the other crank to rotate through the synchronous pulley and figure-eight synchronous belt, without occupying both of the user's hands, thus freeing up one hand and improving ease of use.

[0020] 5. By setting a top cover on the top of the transparent shell, dust can be effectively prevented, which helps to improve hygiene.

[0021] 6. The limiting structure employs a combination of a horizontally sliding limiting pin, an elastic element, and a fixed base. The spherical surface at the end of the limiting pin facilitates smooth contact with the moving partition plate and allows for clearance. Subsequently, it resets under the action of the elastic element, achieving a one-way anti-reverse limiting function. This structure is ingeniously designed and operates reliably.

[0022] 7. By integrating the drive belt assembly and limiting structure onto the expansion boxes on both sides of the transparent housing, the internal space of the transparent housing can be used to maximize the stacking of suction head racks, thus improving space utilization.

Therefore, they should not be construed as limitations on this utility model.

[0026] Example: See Figures 1 to 14 A stacked suction head release structure includes a suction head box 100, a suction head plate holder 200, and a transparent shell 300.

[0027] See Figure 9A top cover 400 is attached to the top of the transparent shell 300.

[0028] See Figure 9 and Figure 10 The transparent housing 300 has expansion boxes 500 on both its left and right sides, and the expansion boxes 500 and the transparent housing 300 are an integral structure. See also Figure 11 The inner cavity of the expansion box 500 is connected to the inner cavity of the transparent shell 300.

[0029] See Figure 11 Inside the transparent housing 300, multiple suction head holders 200 are stacked vertically.

[0030] See Figure 11 and Figure 12 The expansion boxes 500 on both sides of the transparent shell 300 are equipped with transmission belt assemblies and limiting structures.

[0031] See Figure 11 The drive belt assembly includes an upper roller 610, a lower roller 620, a drive belt 630, and separator plates 640. The upper roller 610 and lower roller 620 are rotatably mounted on the side wall of the expansion box 500 via bearings. A drive belt 630 is fitted onto the upper roller 610 and lower roller 620 and is driven by them. Multiple separator plates 640 are fixed at equal intervals along the circumference of the drive belt 630. The separator plates 640 on the side of the drive belt 630 facing the suction head holder 200 support the suction head holder 200.

[0032] See Figure 11 When the left drive belt 630 rotates clockwise and the right drive belt 630 rotates counterclockwise, the partition plate 640 located on the side of the drive belt 630 facing the suction head plate 200 (i.e., the inner side) can support the suction head plate 200 to descend, so that the lowest suction head plate 200 is released into the suction head box 100.

[0033] See Figure 3 The ends of both lower rollers 620 extend to the outside of the extension box 500 and are fixed with crank handles 710. The crank handles 710 allow the user to easily grip and rotate the lower rollers 620, thereby facilitating the operation of the drive belts 630 on the left and right sides.

[0034] Because the crank handles 710 at the ends of the two lower rollers 620 are separate and independent, the user needs to operate one crank handle 710 with each hand when driving the left and right drive belts 630. This embodiment further improves upon this: see [link to previous section]. Figure 13 and Figure 14The ends of the two lower rollers 620 are also fixed with synchronous pulleys 720, which are driven by a figure-eight synchronous belt 730. The figure-eight synchronous belt 730 refers to a synchronous belt that twists in three-dimensional space to present an "eight" shape from the main viewing angle, so that the two synchronous pulleys 720 can rotate synchronously in opposite directions.

[0035] By setting up a synchronous pulley 720 and a figure-eight synchronous belt 730, the user only needs to operate one crank 710 with one hand to drive the other crank 710 to rotate through the synchronous pulley 720 and the figure-eight synchronous belt 730. This eliminates the need to occupy both of the user's hands, freeing up one hand and improving ease of use.

[0036] See Figure 6 and Figure 7 The limiting structure includes a limiting pin 810, an elastic element 820, and a fixing seat 830. The fixing seat 830 is fixed to the outer wall of the expansion box 500. A sliding hole is provided on the side wall of the expansion box 500, and the limiting pin 810 slides in the sliding hole along the horizontal direction. One end of the limiting pin 810 located inside the expansion box 500 has a spherical surface 811, and the bottom of the spherical surface 811 abuts against the partition plate 640 on the outer side of the transmission belt 630. The limiting pin 810 has a limiting ring 812 and a receiving cavity 813 at the end located outside the expansion box 500. The diameter of the limiting ring 812 is larger than the diameter of the sliding hole, which is used to prevent the limiting pin 810 from sliding completely into the expansion box 500. The elastic element 820 is a spring. The elastic element 820 is housed in the receiving cavity 813. One end of the elastic element 820 abuts against the bottom of the receiving cavity 813, and the other end abuts against the fixed seat 830. The elastic element 820 is used to push the limiting pin 810 to slide into the interior of the expansion box 500.

[0037] The working principle is as follows: In the initial state, inside the transparent housing 300, each suction head holder 200 is supported on both the left and right sides by a partition plate 640. Furthermore, inside the expansion box 500, the partition plate 640 is blocked by a limiting pin 810. When no external force drives the drive belt 630, the limiting pin 810 prevents the drive belt 630 from rotating (preventing the left drive belt 630 from rotating clockwise and the right drive belt 630 from rotating counterclockwise), thus preventing the suction head holder 200 inside the transparent housing 300 from accidentally releasing from the lower end of the transparent housing 300.

[0038] When it is necessary to release the bottom suction head holder 200 inside the transparent housing 300, the user first places the transparent housing 300 on top of the suction head box 100, so that the inner cavity of the transparent housing 300 is connected to the inner cavity of the suction head box 100.

[0039] Then, the user rotates either crank 710, which drives the lower rollers 620 on both sides to rotate synchronously via the synchronous pulley 720 and the figure-eight synchronous belt 730, thereby driving the transmission belts 630 on both sides to move (the left transmission belt 630 rotates clockwise and the right transmission belt 630 rotates counterclockwise). The partition plate 640 located outside the transmission belt 630 presses against the spherical surface 811 of the limiting pin 810, overcoming the elastic force of the elastic element 820 and pushing the limiting pin 810 outward, thus allowing the partition plate 640 to pass smoothly upward. After the partition plate 640 passes, the limiting pin 810 quickly resets under the action of the elastic element 820, and the partition plate 640 supporting the lower suction head plate 200 moves away from the sides of the suction head plate 200 along with the transmission belt 630, allowing the lower suction head plate 200 to be released into the suction head box 100.

[0040] When the partition plate 640 of the lowest suction head plate 200 comes into contact with the bottom of the spherical surface 811 of the limit pin 810, the partition plate 640 on the inner side of the transmission belt 630 supports the remaining suction head plates 200 downwards by one layer distance (i.e., the distance between two adjacent suction head plates 200), so that the new suction head plate 200 reaches the release position.

[0041] Based on the above working principle, it can be seen that this embodiment has the following advantages: In this embodiment, each suction head holder 200 stacked inside the transparent housing 300 is supported and separated by a partition plate 640. By rotating the transmission belt 630, the partition plate 640 on the inner side of the transmission belt 630 can smoothly support and transport the suction head holder 200 downwards. On the one hand, this embodiment changes the press-release method in the prior art to a rotation-release method, which can avoid the occurrence of chain reactions due to excessive pressing by the user and improve the release accuracy. On the other hand, when the user rotates to release the suction head holder 200, the transmission belt 630 is rotated from the side of the transparent housing 300, which allows the user to observe from the side of the transparent housing 300 whether the suction head holder 200 has been accurately released, which also helps to improve the release accuracy.

[0042] By setting limiting structures on the left and right sides of the transparent housing 300 to work in conjunction with the transmission belt assembly, the partition plate 640 on the outside of the transmission belt 630 can cyclically abut against the bottom of the limiting structure. When there is no external force driving the transmission belt 630 to run, the limiting structure can limit the partition plate 640 to prevent the transmission belt 630 from running. This can prevent the suction head frame 200 inside the transparent housing 300 from being accidentally released from the lower end of the transparent housing 300, thus improving the reliability of use.

[0043] By providing a crank handle 710 at the end of the lower roller 620, a clear and convenient manual operation interface is provided for the user, making the release action easy to control and execute.

[0044] By setting synchronous pulleys 720 connected by figure-eight synchronous belts 730 at the ends of the two lower rollers 620, it is ensured that the transmission belt assemblies on the left and right sides can operate in precise and synchronous manner, avoiding the risk of the suction head plate frame 200 being jammed or damaged due to asynchrony on both sides, and further improving the reliability and stability of use.

[0045] By setting a top cover 400 on the top of the transparent housing 300, dust can be effectively prevented, which helps to improve hygiene.

[0046] The limiting structure employs a combination of a horizontally sliding limiting pin 810, an elastic element 820, and a fixed base 830. The spherical surface 811 at the end of the limiting pin 810 facilitates smooth contact and clearance with the moving partition plate 640, and then resets under the action of the elastic element 820, achieving a one-way anti-reverse limiting function. This structure is ingeniously designed and operates reliably.

[0047] By integrating the drive belt assembly and limiting structure onto the expansion boxes 500 on both sides of the transparent housing 300, the internal space of the transparent housing 300 can be maximized for stacking the suction head rack 200, thus improving space utilization.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
