Description

A laboratory electronic pipette Technical Field

[0001] This utility model relates to the field of electronic pipette technology, and specifically to an electronic pipette for laboratory use. Background Technology

[0002] In biological laboratories, pipettes are often needed. Electronic pipettes, also known as pipettes, are measuring tools that transfer liquid from one container to another within a certain range. They are widely used in fields such as biology and chemistry.

[0003] Existing electronic pipettes are usually placed horizontally on the workbench after use, which can lead to contamination by debris on the workbench. This can result in the debris from the electronic pipette entering the sampled liquid during subsequent pipetting. Therefore, there is a need for a laboratory electronic pipette that can be suspended in the air by a support device to prevent it from contacting the workbench when placed. Summary of the Invention

[0004] Therefore, this utility model provides a laboratory electronic pipette, which solves the problem that electronic pipettes are usually placed horizontally on the workbench after use, and are contaminated by debris on the workbench through a pipette support unit (2).

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laboratory electronic pipette, comprising an electronic pipette assembly, the electronic pipette assembly comprising an electronic pipette body, an empty slot on one side of the electronic pipette body, side slots on both sides of the empty slot, a plurality of limiting trapezoidal slots on one side of the empty slot, a pipette support unit connected inside the empty slot, the pipette support unit comprising a support plate, a connecting block fixedly provided on one side of the support plate, side strips on both sides of the connecting block, a cavity inside the connecting block, a spring provided inside the cavity, and a limiting trapezoidal block provided at one end of the spring.

[0006] Preferably, the connecting block is disposed inside the empty groove and is slidably connected to the empty groove.

[0007] Preferably, the side strip extends into the side groove and is slidably connected to the side strip.

[0008] Preferably, one end of the spring is fixedly connected to one end of the cavity, and the other end of the spring is fixedly connected to one side wall of the limiting trapezoidal block.

[0009] Preferably, the limiting trapezoidal block is disposed inside the cavity and is slidably connected to the cavity.

[0010] Preferably, one end of the limiting trapezoidal block extends out of the cavity and is slidably connected to one side wall of the cavity.

[0011] Preferably, one end of the limiting trapezoidal block extending outside the cavity extends into the limiting trapezoidal groove and is slidably connected to the limiting trapezoidal groove.

[0012] The present invention has the following advantages:

[0013] With the designed pipette support unit, the electronic pipette body can be suspended in the air, avoiding direct contact with the workbench surface. This effectively prevents debris on the workbench from contaminating the electronic pipette, ensuring the cleanliness and accuracy of subsequent pipetting operations.

[0014] The design of the limiting trapezoidal block and limiting trapezoidal groove in the pipette support unit allows the support unit to be flexibly adjusted according to the center of gravity of the electronic pipette. Once the position is adjusted, the limiting trapezoidal block will be firmly locked in the corresponding limiting trapezoidal groove due to the elastic force of the spring, keeping the electronic pipette stable.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Referring to Figures 1-5, the present invention provides a laboratory electronic pipette, including an electronic pipette assembly 1. The electronic pipette assembly 1 includes an electronic pipette body 11. A slot 12 is provided on one side of the electronic pipette body 11, and side slots 13 are provided on both sides of the slot 12. A plurality of limiting trapezoidal slots 14 are provided on one side of the slot 12. A pipette support unit 2 is connected inside the slot 12. The pipette support unit 2 includes a support plate 21. A connecting block 22 is fixedly provided on one side of the support plate 21. Side strips 23 are provided on both sides of the connecting block 22. A cavity 24 is provided inside the connecting block 22. A spring 25 is provided inside the cavity 24. A limiting trapezoidal block 26 is provided at one end of the spring 25.

[0025] In this embodiment, in order to achieve the purpose of suspending the electronic pipette in the air by the support device and preventing the electronic pipette from contacting the workbench surface when it is placed horizontally, it is necessary to drag the pipette support unit 2 to move it when the electronic pipette assembly 1 is placed horizontally, so that the pipette support unit 2 is at the center of gravity of the electronic pipette assembly 1. This prevents the electronic pipette assembly 1 from tilting after being placed horizontally on the workbench surface by the pipette support unit 2. It also makes it easier for the electronic pipette body 11 to be placed horizontally on the workbench surface by the support plate 21 in the pipette support unit 2, avoiding direct contact with the workbench surface. This can effectively prevent debris on the workbench surface from contaminating the electronic pipette and ensure the cleanliness and accuracy of subsequent pipetting operations.

[0026] In order to prevent the pipette support unit 2 from detaching from the electronic pipette assembly 1, the device adopts the following technical solution: the connecting block 22 is located inside the empty slot 12 and is slidably connected to the empty slot 12; the side strip 23 extends into the side slot 13 and is slidably connected to the side strip 23; when the pipette support unit 2 is adjusted, the connecting block 22 slides inside the empty slot 12; through the cooperation between the side strip 23 and the side slot 13, the connecting block 22 is prevented from coming out of the empty slot 12, so that the pipette support unit 2 is always connected to the electronic pipette assembly 1.

[0027] To facilitate adjustment of the pipette support unit 2's center of gravity position based on the electronic pipette assembly 1, the device employs the following technical solution: one end of spring 25 is fixedly connected to one end of cavity 24, and the other end of spring 25 is fixedly connected to one side wall of limiting trapezoidal block 26. Limiting trapezoidal block 26 is located inside cavity 24 and slidably connected to cavity 24. One end of limiting trapezoidal block 26 extends outside cavity 24 and slidably connects to one side wall of cavity 24. The other end of limiting trapezoidal block 26 extending outside cavity 24 extends into limiting trapezoidal groove 14 and slidably connects to limiting trapezoidal groove 14. When connecting block 22 moves, it drives the limiting trapezoidal block... When block 26 moves, the inclined surface of the limiting trapezoidal block 26 engages with the inclined surface of the limiting trapezoidal groove 14, causing the limiting trapezoidal block 26 to slide into the cavity 24. This causes the spring 25 to contract. When the limiting trapezoidal block 26 moves to the new limiting trapezoidal groove 14, the elastic force of the spring 25 causes the limiting trapezoidal block 26 to insert into the new limiting trapezoidal groove 14. This allows the pipette support unit 2 to slide freely along the empty groove 12 during manual operation, and to remain fixed at a certain position in the empty groove 12 during non-manual operation. This eliminates the need to adjust the pipette support unit 2 every time the electronic pipette assembly 1 is placed horizontally, improving the convenience of use.

[0028] The usage process of this utility model is as follows: When using this utility model, if the electronic pipette assembly 1 needs to be laid horizontally, drag the pipette support unit 2 to move it, so that the pipette support unit 2 is at the center of gravity of the electronic pipette assembly 1, preventing the electronic pipette assembly 1 from tilting after being laid horizontally on the workbench via the pipette support unit 2. When adjusting the pipette support unit 2, the connecting block 22 slides inside the empty groove 12. Through the cooperation of the side strip 23 and the side groove 13, the connecting block 22 is prevented from coming out of the empty groove 12, so that the pipette support unit 2 is always connected to the electronic pipette assembly 1. When the connecting block 22 moves, it drives the limiting ladder. When block 26 moves, the inclined surface of the limiting trapezoidal block 26 engages with the inclined surface of the limiting trapezoidal groove 14, causing the limiting trapezoidal block 26 to slide into the cavity 24. This causes the spring 25 to contract. When the limiting trapezoidal block 26 moves to the new limiting trapezoidal groove 14, the elastic force of the spring 25 causes the limiting trapezoidal block 26 to insert into the new limiting trapezoidal groove 14. This allows the pipette support unit 2 to slide freely along the empty groove 12 during manual operation, and to remain fixed at a certain position in the empty groove 12 during non-manual operation. This eliminates the need to adjust the pipette support unit 2 every time the electronic pipette assembly 1 is placed horizontally, improving the convenience of use.

[0029] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
