Description

Technical Field

[0001] This utility model relates to the field of pipette holder technology, and in particular to a pipette holder. Background Technology

[0002] A pipette is an extremely important precision instrument in the laboratory, primarily used for accurately measuring and transferring a specific volume of liquid. Its volumetric range is diverse, from a few microliters to several milliliters, meeting the precision requirements of various experiments. A pipette typically consists of a pipette body, a piston, a push rod, and a tip connection. During operation, pressing the push rod moves the piston, changing the internal pressure of the pipette to achieve liquid aspiration and dispensing. Its ingenious design ensures high accuracy and repeatability during liquid aspiration and transfer. Whether precisely adding various reagents in cell culture experiments or accurately measuring reaction solutions in chemical analysis experiments, the pipette plays a crucial role, providing strong assurance for the reliability and reproducibility of experimental results, and greatly improving the efficiency and quality of experimental operations.

[0003] Pipette racks are primarily used to secure pipettes, preventing them from rolling or being damaged by collisions, and providing a safe and stable storage environment. Common pipette racks come in various styles; some use a slot-type design, allowing pipettes to be precisely inserted into the corresponding sized holes; others are equipped with slots, ensuring the pipettes are securely held in place. In terms of materials, some are made of plastic, which is lightweight and inexpensive, while others are made of metal, which is more robust and durable. The racks also feature labeled areas to help researchers quickly locate the required pipette volume. Using pipette racks not only extends the lifespan of pipettes and prevents damage from improper placement that could affect accuracy, but also improves the tidiness of the laboratory space and the ease of operation, allowing researchers to quickly and accurately retrieve pipettes when needed, thus ensuring efficient and orderly experimental work.

[0004] However, some existing pipettes are tightly bound by a holder when placed, and their positions are relatively fixed. When researchers need to rotate the pipette to adjust the tip angle or perform precise operations, they are often restricted by the holder and cannot flexibly change the angle. When it is urgent to retrieve the pipette for experimental operations, the process is extremely inconvenient, and researchers have to spend extra time and effort to retrieve the pipette. This not only affects the smoothness of experimental operations, but also reduces experimental efficiency to a certain extent, and hinders the smooth progress of experiments. Therefore, in order to address the above shortcomings, a pipette holder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pipette holder, which aims to improve the problem that some pipette holders in the prior art are not convenient for rotating and picking up pipettes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipette holder includes a base, a rotating rod rotatably connected to the top of the base, a rotating handle fixedly connected to the top of the rotating rod, a fixed plate fixedly connected to the outer top side of the rotating rod, multiple guide blocks fixedly connected inside the fixed plate, a protective sleeve fixedly connected to the bottom of each of the multiple guide blocks, a pipette assembly disposed inside the protective sleeve, a rotating disk fixedly connected to the bottom of the rotating rod, multiple slots formed inside the rotating disk, a fixed ring fixedly connected to the inner right side of the base, a sliding groove formed on the inner bottom side of the fixed ring, an elastic component disposed inside the fixed ring, a pull plate fixedly connected to the top of the elastic component, a sliding plate fixedly connected to the bottom of the elastic component, and a protective component fixedly connected to the outside of the rotating rod.

[0008] As a further description of the above technical solution:

[0009] The pipette assembly includes multiple pipette bodies, the exterior of which is slidably connected to the interior of the fixed plate, and a rotating head is fixedly connected to the top of each of the multiple pipette bodies.

[0010] As a further description of the above technical solution:

[0011] The elastic component includes a sliding rod, the outside of which is slidably connected to the inside of the fixed ring, and a spring is sleeved on the outside of the sliding rod;

[0012] As a further description of the above technical solution:

[0013] The protective assembly includes a protective disc, the inside of which is fixedly connected to the outside of the rotating rod, and multiple protective sleeves are fixedly connected inside the protective disc. Multiple suction cups are fixedly connected to the bottom of the base.

[0014] As a further description of the above technical solution:

[0015] The bottom of the pipette body is slidably connected to the inside of the protective sleeve, which is made of thermoplastic elastomer.

[0016] As a further description of the above technical solution:

[0017] The rotating disk is rotatably connected to the inside of the base, and the sliding disk is slidably connected to the inside of the slot.

[0018] As a further description of the above technical solution:

[0019] One end of the spring is fixedly connected to the bottom of the pull plate, and the other end of the spring is fixedly connected to the top of the fixing ring;

[0020] As a further description of the above technical solution:

[0021] The sliding disc is externally slidably connected to the inside of the slide groove, and the inside of the protective sleeve is provided with protective sponge.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, when the placement rack needs to be rotated, pulling the pull plate causes the sliding rod to shift, allowing the sliding plate to slide out of the slot inside the rotating plate and into the groove on the bottom side of the fixing ring. At this time, the spring is stretched, and the user rotates the handle, which in turn rotates the fixing plate and the rotating plate together, allowing the pipette body in different positions to be rotated to a more accessible side. After the operation is completed, releasing the pull plate causes the spring force to return the sliding plate to its original position and slide into the slot, locking the rotating plate and the rotating rod. In laboratory settings where pipettes are frequently used, users no longer need to search through numerous pipettes; they can quickly rotate the required pipette to a convenient position, greatly saving operation time and improving experimental efficiency.

[0024] 2. In this utility model, the suction cup adheres tightly to the tabletop, providing stable support for the entire placement rack. This effectively prevents the rack from shifting or tipping over during experiments due to external factors such as personnel movement or instrument vibration, thus ensuring the stability of the pipette placed on it. The guide block guides the pipette body through the protective sleeve for fixation. The protective sponge inside the protective sleeve cushions the pipette from collisions or scratches that may occur during placement, preventing external damage to the pipette. At the same time, it also prevents dust and impurities from entering the pipette and affecting its accuracy and service life to a certain extent. When the pipette body is placed into the protective sleeve, its bottom enters the protective sleeve. The protective sleeve is made of thermoplastic elastomer material, which has good flexibility and wear resistance, effectively cushioning and protecting the bottom of the pipette, preventing damage to the bottom during placement, and providing comprehensive protection for the pipette, extending its service life, and ensuring the accuracy and stability of experimental operations.

[0031] 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.

[0032] Reference Figures 2 to 4This utility model provides an embodiment of a pipette holder, including a base 1. The base 1 serves as the basic support structure for the entire pipette holder, bearing the entire weight of the holder and ensuring its stability in the working environment. A rotating rod 2 is rotatably connected to the top of the base 1, and a rotating handle 3 is fixedly connected to the top of the rotating rod 2. When it is necessary to rotate the holder to facilitate the retrieval of pipettes, the user can easily rotate the rotating rod 2 by operating the rotating handle 3. A fixing plate 4 is fixedly connected to the outer top side of the rotating rod 2. Multiple guide blocks 5 are fixedly connected to the inside of the fixing plate 4, and a protective sleeve 6 is fixedly connected to the bottom of each guide block 5. The guide blocks 5 guide and position the pipette body 7, allowing the pipette body 7 to smoothly pass through the protective sleeve 6 along the direction of the guide blocks 5 and be fixed. The protective sleeve 6 is provided with protective sponge inside. When the pipette body 7 passes through the protective sleeve 6, the protective sponge can make close contact with the surface of the pipette body 7, providing cushioning and protection to prevent the pipette body 7 from being damaged by collision or scratch during placement. The protective sleeve 6 not only protects the exterior of the pipette body 7 but also prevents dust and impurities from entering the pipette and affecting its accuracy and lifespan. Inside the protective sleeve 6 is a pipette assembly comprising multiple pipette bodies 7. The exteriors of these pipette bodies 7 are slidably connected to the interior of the fixed plate 4. A rotating head 8 is fixedly connected to the top of each pipette body 7. The rotating head 8 is designed to allow users to easily rotate the pipette body 7 to adjust the aspiration or dispensing angle. A rotating disk 9 is fixedly connected to the bottom of the rotating rod 2, and the exterior of the rotating disk 9 is rotatably connected to the interior of the base 1.

[0033] The rotating disk 9 has multiple slots 10 inside. When the placement rack needs to be rotated, pulling the pull plate 15 causes the sliding disk 16 to slide out of the slots 10. At this time, the rotating disk 9 and the rotating rod 2 can rotate freely. When the sliding disk 16 slides into the slots 10, the rotating disk 9 and the rotating rod 2 are locked and cannot rotate freely, ensuring the stability of the placement rack when placing pipettes normally. A fixing ring 11 is fixedly connected to the right side of the inside of the base 1. The fixing ring 11 is mainly used to install and fix the elastic component, providing a stable support structure for the elastic component. A sliding groove 12 is opened on the bottom side of the inside of the fixing ring 11. When pulling the pull plate 15 causes the sliding rod 13 and the sliding disk 16 to move, the sliding disk 16 will slide out of the slots 10 and into the sliding groove 12. At this time, the rotating disk 9 and the rotating rod 2 can rotate freely. The fixed ring 11 has an internal elastic component, which includes a sliding rod 13. The sliding rod 13 is slidably connected to the inside of the fixed ring 11. When the user pulls the pull plate 15, the pull plate 15 causes the sliding rod 13 to move within the fixed ring 11, thereby moving the sliding disk 16. A spring 14 is sleeved on the outside of the sliding rod 13. The pull plate 15 is fixedly connected to the top of the elastic component. One end of the spring 14 is fixedly connected to the bottom of the pull plate 15, and the other end of the spring 14 is fixedly connected to the top of the fixed ring 11. The spring 14 provides elastic force in the elastic component. When the pull plate 15 is pulled to make the sliding disk 16 slide out of the slot 10, the spring 14 will stretch and deform, storing elastic potential energy. When the pull plate 15 is released, the spring 14 will release the elastic potential energy, pushing the pull plate 15 and the sliding rod 13 to reset, thereby causing the sliding disk 16 to slide back into the slot 10, thus locking the rotating disk 9 and the rotating rod 2. A sliding plate 16 is fixedly connected to the bottom of the elastic component. The external part of the sliding plate 16 is slidably connected to the inside of the slot 10. When the pull plate 15 is pulled, the sliding plate 16 slides out of the slot 10 and into the slide groove 12, allowing the rotating disk 9 and the rotating rod 2 to rotate freely. When the pull plate 15 is released, under the elastic force of the spring 14, the sliding plate 16 slides back into the slot 10, locking the rotating disk 9 and the rotating rod 2. The external part of the sliding plate 16 is slidably connected to the inside of the slide groove 12.

[0034] Reference Figure 1 and Figure 2The rotating rod 2 is externally fixedly connected to a protective assembly, which includes a protective disc 18. The protective disc 18 is internally fixedly connected to the outside of the rotating rod 2. The protective disc 18 serves to support and fix the protective sleeve 19, and also provides some protection for the protective sleeve 19 and the bottom of the pipette body 7 placed inside the protective sleeve 19. Multiple protective sleeves 19 are fixedly connected inside the protective disc 18. The bottom of the pipette body 7 is slidably connected to the inside of the protective sleeve 19. When the pipette body 7 is placed into the protective sleeve 6, its bottom will enter the inside of the protective sleeve 19. The protective sleeve 19 can cushion and protect the bottom of the pipette body 7, preventing the bottom from being damaged by collision or scratch during placement. Multiple suction cups 17 are fixedly connected to the bottom of the base 1. When the suction cup 17 is pressed on the table, the internal air is squeezed out, forming a negative pressure, so that the suction cup 17 can be firmly attached to the table. The protective sleeve 19 is made of thermoplastic elastomer material.

[0035] Working principle: When using this pipette holder, the holder can first be attached to the tabletop using the suction cup 17. Then, the pipette body 7 can be fixed by passing it through the inside of the protective sleeve 6. This allows for the placement and fixation of the pipette body 7. When the pipette body 7 is placed inside the protective sleeve 6, the bottom of the pipette body 7 will enter the inside of the protective sleeve 19, thus protecting the bottom of the pipette body 7. The protective sleeve 6 and the protective sleeve 19 can be used to position and protect the pipette body 7, ensuring the stability of the pipette body 7. At the same time, the suction cup 17 can ensure the stability of the holder body.

[0036] When it is necessary to rotate the placement rack for easy access, first pull the pull plate 15 to move the sliding rod 13, which in turn moves the sliding plate 16. At this time, the sliding plate 16 can slide out from the inside of the slot 10 until it slides into the inside of the slide groove 12. This will stretch the spring 14. Then, turn the handle 3 to rotate the rotating rod 2 and the fixed plate 4, causing the rotating plate 9 to rotate. Then, rotate a pipette body 7 to the side that is easy to access. Then, release the pull plate 15 and the spring force of the spring 14 will allow the sliding plate 16 to return to its original position and slide back into the inside of the rotating plate 9, thereby locking the rotating plate 9 and the rotating rod 2.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
