Description

Technical Field

[0001] The utility model relates to the technical field of pipettes, in particular to a pipette with a supporting structure. Background Art

[0002] A pipette, also known as a pipette gun, is a measuring tool used to transfer liquid from one container to another within a certain range. The pipette needs to be well supported during use. When the pipette is well supported, its components can remain in a relatively stable position. In a laboratory environment, for example, there may be various sources of vibration, such as the operation of instruments and equipment, and the movement of people. If the pipette is not supported, these vibrations can easily be transmitted to the internal structure of the pipette, potentially causing certain vulnerable parts of the pipette, such as the tip interface, to collide unnecessarily with the desktop or other hard objects.

[0003] The prior art, such as publication number CN220900457U, provides a pipette, including a bracket, a first fixed plate fixed at the axis center of the top of the bracket, a second fixed plate fixed on the top of the first fixed plate, a plurality of support plates fixed on the outside of the second fixed plate, a plurality of pipette bodies are arranged on the outside of the support plate, a grip placed on the outside of the support plate is fixed on the outside of the pipette body, a protective component is provided on one side of the pipette body, the protective component includes a plurality of fixing frames and a plurality of baffles, which are inserted into the inner side of the third limiting groove through a connecting column, and the force of pulling the pull rod is released. Under the elastic force of the spring, the locking block is inserted into the inner side of the locking groove, and a baffle is provided on the outside of the needle tube of the suspended pipette body to prevent external contaminants from contacting the needle tube position of the pipette body, and to avoid the possibility of the needle tube of the pipette body being contaminated by the external environment when not in use, thereby improving the cleanliness of the pipette body when it is suspended.

[0004] In this solution, the outer side of the needle of the suspended pipette body is shielded by a baffle to prevent external contaminants from contacting the needle position of the pipette body, thereby preventing the needle of the pipette body from being contaminated by the external environment when not in use. This improves the cleanliness of the pipette body when it is suspended. However, if a pipette is needed during virus testing to extract a solution containing the virus from a vessel and transfer it to test equipment or other vessels, a small amount of residual liquid may remain on the outer wall of the needle, which is easy to drip or spread into the air, causing pollution to the surrounding environment and posing a certain hazard to the operator. In view of this, we propose a pipette with a support structure. Utility Model Content

[0005] The purpose of the utility model is to provide a pipette with a support structure, which solves the problem that a small amount of residual liquid remains on the outer wall of the needle tube and is easy to drip or diffuse in the air, causing pollution to the surrounding environment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pipette with a support structure comprises a pipette body, a needle of the pipette body is provided with a protective mechanism, and the outside of the pipette body is provided with a support mechanism;

[0008] The protective mechanism has two groups of storage shells, and the two groups of storage shells are respectively fixedly connected to the two sides of the outer wall of the pipette body, and a slide groove is opened on the storage shell. The inner wall of the slide groove is slidably connected to a slide rod, and one end of the slide rod inside the storage shell is fixedly connected to a semi-cylinder.

[0009] Preferably, the two groups of semi-cylinders are used to wrap the needle area of ​​the pipette body, and the bottoms of the semi-cylinders are fixedly connected to the second magnetic blocks.

[0010] Preferably, the storage shell is fixedly connected to a first magnetic block at the bottom of the slide slot, and the end of the slide rod away from the slide slot is fixedly connected to a pressure plate.

[0011] Preferably, the support mechanism comprises four groups of slideways, the four groups of slideways are fixedly connected to the outer wall of the pipette body, and the outer walls of the slideways are slidably connected to sliders, and the outer walls of the sliders are hinged with supporting feet.

[0012] Preferably, the bottoms of the legs are fixedly connected with rubber pads, and a push ring is provided on the outside of the pipette body, and both sides of the push ring are slidably connected with the outer walls of the corresponding sliding rods.

[0013] Preferably, a connecting rod is fixedly connected to the inner wall of the push ring at a position corresponding to each supporting leg, for connecting the supporting legs.

[0014] Preferably, one end of the connecting rod is connected to a limiting column at the support leg, a limiting groove is provided on the inner wall of the support leg corresponding to the position of the limiting column, and the limiting column is slidably connected to the limiting groove.

[0015] By means of the above technical solution, the present invention provides a pipette with a support structure, which has at least the following beneficial effects:

[0016] 1. After the pipette body has completed sampling, the present invention pushes the pressure plate to drive the slide bar to slide down the slide groove, so that the semi-cylinder connected to the slide bar slides out of the storage shell. After the storage shell slides out, the pressure plate is pushed to make the two sets of semi-cylinders splice and wrap around the needle area of ​​the pipette body to form a seal, thereby preventing a small amount of residual liquid from remaining on the outer wall of the needle, which is easy to drip or spread in the air and cause pollution to the surrounding environment.

[0017] 2. In the present invention, when the pressing plate drives the slide bar to slide down the slide groove, the slide bar will drive the push ring to descend together, and the push ring drives the hinged support legs on the slider to descend, so as to facilitate the descent and unfolding for support, thereby ensuring the stability of the pipette body when placed.

[0027] In this embodiment, after the pipette body 1 completes sampling, the slide rod 23 is driven to slide down the slide groove 22 by pushing the pressure plate 25, so that the semi-cylinder 24 connected to the slide rod 23 slides out of the storage shell 21. After the storage shell 21 slides out, the pressure plate 25 is pushed so that the two groups of semi-cylinders 24 are spliced ​​and wrapped in the needle area of ​​the pipette body 1 to form a seal.

[0028] Example 2

[0029] like Figure 3 As shown, the two groups of semi-cylinders 24 are used to wrap the needle area of ​​the pipette body 1, and the bottom of the semi-cylinders 24 are fixedly connected to the second magnetic block 27, and the position of the storage shell 21 at the bottom of the slide groove 22 is fixedly connected to the first magnetic block 26.

[0030] In this embodiment, by providing the second magnetic block 27 and the first magnetic block 26 , the semi-cylinder 24 can be fixed by the magnetic attraction generated by the second magnetic block 27 and the first magnetic block 26 after splicing to ensure the stability of the splicing.
