It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0029] Currently, in medical experiments, pipettes are often used to transfer reagents. However, existing pipettes can only be placed in pipette racks. When it is necessary to temporarily store or retrieve pipettes, the distance between the pipette racks and the experimental equipment makes it inconvenient to pick up or put down pipettes.

[0030] In response, this application proposes a clamping assembly 100 for a pipette.

[0031] Please refer to the appendix below. Figures 1-4 The clamping assembly 100 for a pipette according to an embodiment of this application is described as follows: Figure 1 and Figure 2 As shown, the pipette clamping assembly 100 according to an embodiment of this application includes: a base 11; and a clamping part 12, which is connected to the base 11 and used to clamp or release the pipette 200. This facilitates the clamping or releasing of the pipette 200 using the clamping part 12, thereby facilitating the fixation and use of the pipette 200.

[0032] It is understandable that the clamping part 12 can be a clamping claw or a clamping clamp or other clamping fixture that can clamp and release, and there is no limitation here.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, the clamping assembly 100 for the pipette also includes an adsorption assembly 20, which includes a mounting plate 21 and a vacuum suction cup 22. The mounting plate 21 is connected to the side of the base 11 away from the clamping part 12 and extends in the horizontal direction. The vacuum suction cup 22 is connected to the side of the mounting plate 21 in the vertical direction and is used to adsorb onto the experimental table surface.

[0034] This avoids interference between the vacuum suction cup 22 and the pipette clamp 10, and allows the pipette clamp 10 to be adsorbed onto the experimental equipment or experimental table surface through the vacuum suction cup 22, thereby achieving temporary fixation of the pipette clamp 10, and thus temporary fixation of the pipette 200, thereby improving the convenience of picking up and putting down the pipette 200.

[0035] In particular, the mounting plate 21 extends horizontally, and the vacuum suction cup 22 is connected to one side of the mounting plate 21 in the vertical direction, with the opening of the vacuum suction cup 22 open in the vertical direction. This allows the vacuum suction cup 22 to achieve adsorption in the vertical direction. Since the mounting plate 21 extends horizontally, the force on the vacuum suction cup 22 is more uniform, thereby improving the adsorption stability of the vacuum suction cup 22.

[0036] Among them, such as Figure 3 As shown, the base 11 is provided with a connection structure 13 for connecting to the mounting plate 21. The connection structure 13 includes a first snap-fit ​​portion 131 and a first magnetic attachment portion 132, as shown. Figure 4As shown, the mounting plate 21 is provided with a second clamping portion 211 and a second magnetic attraction portion 212, the first clamping portion 131 is clamped and matched with the second clamping portion 211, and the first magnetic attraction portion 132 is magnetically attracted and matched with the second magnetic attraction portion 212.

[0037] In this way, the adsorption assembly 20 can be detachably connected with the pipette clamp 10, so that the user can flexibly select and match according to the use requirement. Meanwhile, the first clamping portion 131 is clamped and matched with the second clamping portion 211, and the first magnetic attraction portion 132 is magnetically attracted and matched with the second magnetic attraction portion 212, which can enhance the connection stability of the adsorption assembly 20 and the base 11. In particular, when the adsorption assembly 20 is connected with the base 11, the magnetic attraction matching of the first magnetic attraction portion 132 and the second magnetic attraction portion 212 can be used to play a certain positioning role, so as to improve the clamping accuracy of the first clamping portion 131 and the second clamping portion 211, thereby reducing the assembly difficulty of the adsorption assembly 20 and the pipette clamp 10.

[0038] It is worth noting that, in the embodiment of the present application, the first clamping portion 131 and the second clamping portion 211 are clamped and matched, and the first magnetic attraction portion 132 and the second magnetic attraction portion 212 are magnetically attracted and matched, so that the mounting plate 21 and the base 11 are connected by two ways. In this way, the connection of the two can play an insurance role, avoiding the problem of unstable connection of the two due to clamping failure or magnetic attraction failure.

[0039] According to the clamping assembly 100 for the pipette of the embodiment of the present application, by providing the adsorption assembly 20, the pipette clamp 10 can be adsorbed to the experimental equipment or the experimental table surface by the vacuum adsorbing disc 22, so as to realize the temporary fixing of the pipette clamp 10, and further realize the temporary fixing of the pipette 200, thereby improving the convenience of taking and placing the pipette 200. In particular, the connection structure 13 is arranged on the base 11, so that the adsorption assembly 20 can be detachably connected with the pipette clamp 10, thereby the user can flexibly select and match according to the use requirement. Meanwhile, the first clamping portion 131 is clamped and matched with the second clamping portion 211, and the first magnetic attraction portion 132 is magnetically attracted and matched with the second magnetic attraction portion 212, which can enhance the connection stability of the adsorption assembly 20 and the base 11. In particular, when the adsorption assembly 20 is connected with the base 11, the magnetic attraction matching of the first magnetic attraction portion 132 and the second magnetic attraction portion 212 can be used to play a certain positioning role, so as to improve the clamping accuracy of the first clamping portion 131 and the second clamping portion 211, thereby reducing the assembly difficulty of the adsorption assembly 20 and the pipette clamp 10.

[0040] In some embodiments, as shown in Figure 3 As shown, in the vertical direction, the horizontal height of the first clamping portion 131 and the horizontal height of the first magnetic attraction portion 132 are the same.

[0041] Thus, when the first clamping portion 131 and the second clamping portion 211 are clamped and matched, and the first magnetic attraction portion 132 and the second magnetic attraction portion 212 are magnetically attracted and matched, the mounting plate 21 can be guaranteed to extend in the horizontal direction, and the adsorption effect of the vacuum chuck 22 is further guaranteed, and the problem that the mounting plate 21 is inclined due to the difference between the position height of the clamping and matching of the first clamping portion 131 and the second clamping portion 211 and the position height of the magnetic attraction and matching of the first magnetic attraction portion 132 and the second magnetic attraction portion 212 is avoided, and the stress of the vacuum chuck 22 is uniform, so as to improve the adsorption stability of the vacuum chuck 22.

[0042] In some embodiments, as shown in Figure 3 The connecting structure 13 is provided with a plurality of connecting structures 13, and the adsorption assembly 20 can be connected with any one of the connecting structures 13.

[0043] Thus, the height of the adsorption assembly 20 on the pipette clamp 10 can be adjusted, so as to facilitate the flexible adjustment of the relative position of the adsorption assembly 20 on the pipette clamp 10 according to the use environment and use requirements, thereby expanding the application range of the clamping assembly 100 for the pipette, and further meeting various use requirements of users.

[0044] In some embodiments, one of the first clamping portion 131 and the second clamping portion 211 is configured as a clamping groove, and the other is configured as a clamping protrusion, and the clamping protrusion and the clamping groove are clamped and matched.

[0045] For example, the first clamping portion 131 is configured as a clamping protrusion, and the second clamping portion 211 is configured as a clamping groove, or as shown in Figure 3 The first clamping portion 131 is configured as a clamping groove, and as shown in Figure 4 The second clamping portion 211 is configured as a clamping protrusion, and the clamping protrusion and the clamping groove are clamped and matched, so as to facilitate the enhancement of the connection stability of the adsorption assembly 20 and the pipette clamp 10, and the structure of the clamping protrusion and the clamping groove is relatively simple, which is beneficial to reduce the setting difficulty and cost.

[0046] In some embodiments, in the depth direction of the clamping groove, the inner diameter of the clamping groove gradually decreases, and the outer peripheral wall of the clamping protrusion is arranged in the shape of the clamping groove.

[0047] It can be understood that the inner diameter of the opening of the clamping groove is greater than the inner diameter of the bottom of the clamping groove, and in the direction from the opening of the clamping groove to the bottom of the clamping groove, the inner diameter of the clamping groove gradually decreases, so that in the process of inserting the clamping protrusion into the clamping groove, the inner diameter of the clamping groove gradually decreases, and the inner diameter of the opening of the clamping groove is greater than the inner diameter of the bottom of the clamping groove to facilitate the insertion of the clamping protrusion, thereby reducing the assembly difficulty of the clamping protrusion and the clamping groove.

[0048] In some embodiments, at least one of the first magnetic attraction portion 132 and the second magnetic attraction portion 212 is configured as a magnet.

[0049] For example, the first magnetic attraction part 132 is a magnet, and the second magnetic attraction part 212 is a metal part that is magnetically attracted to the magnet; or the first magnetic attraction part 132 is a metal part that is magnetically attracted to the magnet, and the second magnetic attraction part 212 is a magnet; or both the first magnetic attraction part 132 and the second magnetic attraction part 212 are magnets and their polarities are opposite.

[0050] This makes it easier to reduce the difficulty of setting up the first magnetic attraction part 132 and the second magnetic attraction part 212, and the cost of the magnet or the metal part that is magnetically attracted to the magnet is low, which helps to reduce production costs.

[0051] In some embodiments, the depth of the snap-fit ​​groove is the same as the sum of the height of the first magnetic part 132 and the height of the second magnetic part 212, and the snap-fit ​​protrusion is designed to conform to the shape of the snap-fit ​​groove.

[0052] This ensures that after the snap-fit ​​protrusion is fully inserted into the snap-fit ​​slot, the first magnetic part 132 and the second magnetic part 212 can be attracted together, thus avoiding the problem that the first magnetic part 132 and the second magnetic part 212 cannot be attracted due to insufficient depth of the snap-fit ​​slot.

[0053] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the orthographic projection of the vacuum suction cup 22 onto the mounting plate 21 falls within the mounting plate 21.

[0054] This ensures that the arrangement of the vacuum suction cup 22 does not occupy space in the direction perpendicular to the arrangement direction of the vacuum suction cup 22 and the mounting plate 21, thereby facilitating a reduction in the size of the clamping assembly 100 for the pipette in the direction perpendicular to the arrangement direction of the vacuum suction cup 22 and the mounting plate 21, thus achieving a miniaturized design in this direction.

[0055] In some embodiments, two vacuum suction cups 22 are provided, and the two vacuum suction cups 22 are respectively located on both sides of the mounting plate 21 in the vertical direction. In this way, the clamping assembly 100 for pipettes can be adsorbed onto the experimental equipment or experimental table surface by means of the corresponding vacuum suction cup 22 on either side of the mounting plate 21 in the vertical direction, thereby increasing the applicability of the clamping assembly 100 for pipettes.

[0056] For example, in the use scenario that the pipette 200 needs to be temporarily fixed to the test bench, the vacuum chuck 22 located on the lower side of the mounting plate 21 in the vertical direction can be used to realize adsorption to the test bench. If the structure on the test bench is more, it will cause that the clamping assembly 100 for the pipette does not have enough space to adsorb to the test bench. At this time, the vacuum chuck 22 located on the upper side of the mounting plate 21 in the vertical direction can be used to realize adsorption to the back of the test bench. In this way, the clamping assembly 100 for the pipette can use the corresponding vacuum chuck 22 on any side of the mounting plate 21 in the vertical direction to realize adsorption to the experimental equipment or the test bench, thereby increasing the application range of the clamping assembly 100 for the pipette.

[0057] In some embodiments, the two vacuum chucks 22 are symmetrically arranged. In this way, the difficulty of arranging the two vacuum chucks 22 is reduced, and the layout of the two vacuum chucks 22 is more processed.

[0058] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.

Therefore, the appended claims are intended to include the preferred embodiments and all changes and modifications falling within the scope of the present application.
