Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental device technology, and more specifically, to a drum-type pipette tip box. Background Technology
[0002] In laboratories, pipette tip holders are a commonly used experimental device used to store pipette tips in a sterile and clean container. However, traditional pipette tip holders often have lids that need to be opened and closed wide, which is inconvenient. Furthermore, the capacity of large-capacity pipette tip holders is often limited. Additionally, opening the lid exposes all the pipette tips inside to the outside environment, causing unused tips to become contaminated and affecting subsequent use, thus impacting experimental data. Utility Model Content
[0003] The technical problem this invention aims to solve is that existing pipette tip boxes are inconvenient to open and close, and easily cause unused pipette tips to be contaminated by the outside world. To overcome the above-mentioned defects of the prior art, this invention provides a method that allows opening and closing only at the retrieval port through a retrieval cover, and automatically delivers the pipette tips one by one to the retrieval port through a rotating pusher assembly, without exposing other pipette tips to the outside world, thus preventing contamination of the internal pipette tips and ensuring that experimental data are not affected.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted:
[0005] A drum-type pipette tip holder includes a box body, a rotating pusher assembly, and a cover. A pusher mounting groove is provided in the middle of the box body. A spirally distributed storage groove is provided between the outer wall of the pusher mounting groove and the inner wall of the box body, with the outermost end of the storage groove serving as a retrieval port. The rotating pusher assembly is installed in the pusher mounting groove and is used to progressively push the pipette tip in the storage groove towards the retrieval port. The cover is installed on the top of the box body and seals the top of the box body. A retrieval cover plate is rotatably connected to the cover at the retrieval port for retrieving a single pipette tip, and the retrieval port is opened and closed by rotating and opening the retrieval cover plate. This pipette tip holder significantly increases storage capacity through its spirally distributed storage slots. Furthermore, by retrieving tips only from the dispensing port, it eliminates the need for large openings, ensuring that retrieving one tip does not expose other tips and prevent contamination. The rotating feeding assembly automatically delivers tips one by one to the dispensing port, facilitating easy retrieval and enhancing usability.
[0006] Preferably, the inner walls of both sides of the storage compartment are provided with guide rails for sliding cooperation with the gun head, and the upper part of the gun head is limited on the guide rails on both sides, while the lower part of the gun head is suspended in the storage compartment. The guide rails allow the upper part of the gun head to rest on them and slide along the guide rails, improving the smoothness of the delivery, while ensuring that the gun head only contacts the guide rails, keeping the gun head suspended in the box and avoiding contamination or friction of the gun head.
[0007] Preferably, the rotary pusher assembly includes a rotary shaft, a spring, and a rotary plate. The rotary shaft is rotatably connected to the pusher mounting groove. The spring is helical, sleeved on the rotary shaft and installed in the pusher mounting groove. The inner end of the spring is fixedly connected to the rotary shaft, and the outer end is fixedly connected to the inner wall of the pusher mounting groove. The rotary plate is fixedly sleeved on the rotary shaft and positioned above the storage groove. The rotation of the rotary plate gradually pushes the nozzles exposed above the storage groove to the retrieval port. After the rotary plate is filled with nozzles under the stored force of the spring, as the nozzles are removed one by one, the rotary plate automatically rotates under the action of the spring, thus pushing the nozzles in the storage groove to the retrieval port one by one.
[0008] Preferably, the center of the pusher mounting groove is provided with a circular lower limit groove for the rotating shaft; the lower end of the rotating shaft is rotatably limited within the lower limit groove; a circular upper limit groove for the rotating shaft is provided on the cover corresponding to the lower limit groove; the upper end of the rotating shaft passes through the rotating plate and is rotatably limited within the upper limit groove. By tightening the cover, both ends of the rotating shaft are limited within the upper and lower limit grooves, thus achieving both positioning and rotation of the rotating shaft.
[0009] Preferably, the storage tank includes a first annular channel and a second annular channel running from the inside out; the discharge end of the first annular channel is connected to the inlet end of the second annular channel to achieve a transition; and the sidewall height of the second annular channel is higher than that of the first annular channel, with the height of the rotating plate located between the sidewalls of the first and second annular channels. The two annular channels enable larger storage capacity, facilitate transport, and also facilitate the movement of the rotating plate.
[0010] Preferably, the discharge end of the first annular channel and the feed end of the second annular channel are connected by a straight channel. The straight channel can shorten the travel distance and facilitate a better transition between the two annular channels.
[0011] Preferably, the outer peripheral wall of the rotating plate is provided with a plurality of gun head push plates arranged at intervals along the circumference; each gun head push plate is provided with a pushing notch that pushes forward in the discharge direction between itself and the rotating plate. The pushing notch on the gun head push plate facilitates further advancement of the gun head along the annular channel, ensuring smooth and stable advancement.
[0012] Preferably, the box body is roughly circular, the final discharge section of the storage compartment is a straight section, and the retrieval port protrudes outside the circular trajectory. This structure allows the nozzles to be aligned in a straight line before discharge, ensuring the flatness of the nozzles and facilitating retrieval of the contents from the retrieval port.
[0013] In summary, the advantages of this utility model are that the pipette tip box can greatly increase the storage capacity through the spirally distributed storage slots, and by taking the tip only at the dispensing port, there is no need to open and close the box, ensuring that when taking one tip, other tips are not exposed to the outside, thus preventing contamination of other tips in the box. At the same time, the rotating pusher component can automatically deliver the tips one by one to the dispensing port, making it convenient to take and improving the ease of use.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 1 to 8As shown, a drum-type pipette tip holder includes a box body 1, a rotating feeding assembly 2, and a cover 3. The box body 1 and the cover 3 are approximately circular. The box body 1 is made of a sturdy, durable, and corrosion-resistant material, while the cover 3 must be made of a material that is heat-resistant and UV-transmittable to facilitate moist heat sterilization and UV sterilization. The box body 1 is open at the top, and the cover 3 covers the top surface of the box body 1. A circular feeding mounting groove 11 is provided in the middle of the box body 1. A spirally distributed storage groove 12 is provided between the outer wall of the feeding mounting groove 11 and the inner wall of the box body 1. The storage groove 12 is open at the top, and the outermost end of the storage groove 12 is a retrieval port 120. The final dispensing section of the storage groove 12 is a straight section, and the retrieval port 120 protrudes outside the circular trajectory. The straight section facilitates the alignment of the pipette tips before dispensing, ensuring the flatness of the tips and making it easy to pick up the tips at the retrieval port 120. The rotary pusher assembly 2 is installed in the pusher mounting groove 11, and the rotary pusher assembly 2 is used to gradually push the pipette tip in the storage groove 12 toward the retrieval port 120; the cover 3 is installed on the top of the box body 1 and seals the top of the box body 1. The retrieval cover 4 for taking out a single pipette tip is rotatably connected to the cover 3 at the retrieval port 120. The retrieval cover 4 is connected to the cover 3 by a plastic hinge, and the retrieval port 120 is opened and closed by rotating the retrieval cover 4. The retrieval cover 4 reduces the exposure of the pipette tip to the air when the pipette tip box is in use. The pipette tip holder can greatly increase storage capacity through the spirally distributed storage slots 12. By retrieving the tip only at the dispensing port 120, there is no need to open and close the container, ensuring that when one tip is retrieved, other tips are not exposed to the outside, thus preventing contamination of other tips in the holder. At the same time, the rotating pusher component 2 can automatically deliver the tips one by one to the dispensing port 120 in a drum-like manner, making it convenient to retrieve and improving ease of use.
[0029] like Figures 2 to 5 As shown, guide rails 13 are provided on both inner walls of the storage slot 12 for sliding engagement with the gun head. The upper part of the gun head is limited by the guide rails 13 on both sides, and the lower part of the gun head is suspended in the storage slot 12. The guide rails 13 are made of a material softer than the box body 1 and the cover body 3 to reduce damage to the gun head during use. The material also needs to be smooth enough to facilitate the sliding of the gun head on the guide rails 13. The guide rails 13 allow the upper part of the gun head to rest on them and slide along the guide rails 13, improving the smoothness of delivery. At the same time, it ensures that the gun head only contacts the guide rails 13, keeping the gun head suspended in the box and avoiding contamination or friction of the gun head.
[0030] like Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the rotary pusher assembly 2 includes a rotary shaft 21, an elastic spring 22, and a rotary plate 23. The rotary shaft 21 is rotatably connected to the pusher mounting groove 11. The elastic spring 22 is made of a durable, elastic, and corrosion-resistant metal material. The elastic spring 22 is spiral-shaped and is sleeved on the rotary shaft 21 and installed in the pusher mounting groove 11. The inner end of the elastic spring 22 is fixedly connected to the rotary shaft 21, and the outer end of the elastic spring 22 is fixedly connected to the inner wall of the pusher mounting groove 11. When the elastic spring 22 is charged, it provides rotational power for the entire rotary pusher assembly 2 during use. The rotary plate 23 is fixedly sleeved on the rotary shaft 21 and is located above the storage groove 12. The rotation of the rotary plate 23 gradually pushes the nozzle exposed above the storage groove 12 to the retrieval port 120. After the rotating plate 23 is filled with gun heads by the stored force of the elastic spring 22, as the gun heads are taken out one by one, the rotating plate 23 can be automatically rotated by the elastic spring 22 in the manner of a drum, thereby pushing the gun heads in the storage slot 12 to the retrieval port 120 one by one.
[0031] like Figure 4 and Figure 6 As shown, a circular lower limit groove 111 for the rotating shaft is provided at the center of the pusher mounting groove 11; the lower end of the rotating shaft 21 is rotatably limited within the lower limit groove 111; a circular upper limit groove 31 for the rotating shaft is provided on the cover 3 corresponding to the position of the lower limit groove 111; the upper end of the rotating shaft 21 passes through the rotating plate 23 and is rotatably limited within the upper limit groove 31. By tightening the cover 3, the upper and lower ends of the rotating shaft 21 can be limited on the upper limit groove 31 and the lower limit groove 111, thereby achieving positioning while also allowing the rotating shaft 21 to rotate.
[0032] like Figures 3 to 5 As shown, the storage tank 12 includes a first annular channel 121 and a second annular channel 122 extending from the inside out. The discharge end of the first annular channel 121 is connected to the inlet end of the second annular channel 122 to achieve a transition. The side wall of the second annular channel 122 is higher than the side wall of the first annular channel 121, and the height of the rotating plate 23 is between the side walls of the first annular channel 121 and the second annular channel 122. The rotating plate 23 is positioned higher than the first annular channel 121 and lower than the second annular channel 122, allowing it to push the nozzle along the guide rail 13. The two annular channels enable larger storage capacity, facilitate transport, and also facilitate the pushing of the rotating plate 23. The discharge end of the first annular channel 121 and the inlet end of the second annular channel 122 are connected by a straight channel 123. The straight channel 123 shortens the travel distance and facilitates a better transition between the two annular channels.
[0033] like Figure 7 and Figure 8As shown, four gun head push plates 231 are arranged at equal intervals along the circumference of the outer peripheral wall of the rotating plate 23; each gun head push plate 231 and the rotating plate 23 are provided with a pushing notch 232 that pushes forward in the discharge direction. The pushing notch 232 on the gun head push plate 231 facilitates further advancement of the gun head along the annular channel, ensuring smooth and stable advancement.
[0034] The cartridge-type pipette tip box allows for the insertion of several tips into the first annular channel 121 and the second annular channel 122 by opening the cover 3. As the tips are slowly inserted, the rotating plate 23 rotates counterclockwise, gradually filling the box and storing power until both channels are completely filled. In use, the retrieval cover 4 is opened, and a tip is removed from the retrieval opening 120. Since the retrieval opening 120 is empty, the rotating plate 23 rotates clockwise under the action of the spring 22, allowing the next tip to fill the opening. This process is repeated until all tips are in the retrieval opening 120, at which point the cartridge is refilled.
[0035] With the above method, there is no need for the large opening and closing required by the original structure. The gun tip can be retrieved simply by opening the retrieval cover 4 at the retrieval port 120. At the same time, the chance of other gun tips in the box coming into contact with the outside is reduced when retrieving the gun tip, so as not to cause contamination of other gun tips in the box and to ensure the accuracy of experiments when using the gun tips in the future. The spirally distributed storage slots 12 can greatly increase the storage capacity, and the rotating pusher component 2 can automatically deliver the gun tips to the retrieval port 120 one by one in sequence, which is convenient for retrieval and improves the convenience of use.
