Description

Technical Field

[0001] The utility model relates to the technical field of microscopy, in particular to a quantitative oil dripping device. Background Art

[0002] A microscope is an optical instrument composed of one lens or a combination of several lenses. It is often used in the process of drug microbiological testing. When in use, due to the tiny size of microorganisms, cedar oil needs to be dripped onto the slide when collecting images under the microscope to allow as much light as possible to enter the objective lens, thereby enhancing the brightness of the field of view and making the image bright and clear.

[0003] At present, the existing microscope slide oil dripping method is usually manual squeezing oil dripping. Specifically, the operator uses a rubber-tipped dropper to draw cedar oil from the oil bottle, and then moves it to the top of the slide to squeeze and drip the oil. However, in actual use, the above method cannot accurately control the amount of oil dripped on the slide. There are often problems such as insufficient oil dripping, which requires the operator to repeatedly squeeze and drip oil, or excessive oil dripping, which causes oil droplets to overflow and requires the operator to clean before reading the film, which seriously affects the efficiency of film reading. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a quantitative oil dripping device to solve the technical problem that the amount of oil cannot be accurately controlled when dripping oil on a glass slide.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quantitative oil dripping device, comprising a pipette, one end of the pipette is fixedly connected to a liquid outlet tube, the outer side of the liquid outlet tube is sleeved with a fixed shell, one side of the fixed shell is rotatably connected to a rotating shell through a torque shaft, arc grooves are provided inside the fixed shell and the rotating shell, a cavity is provided below the arc groove, and the cavity is connected to the liquid outlet tube.

[0006] By adopting the above technical solution, the fixed connection between the pipette and the liquid outlet tube ensures that the immersion oil can be stably and accurately sucked up, and the liquid outlet tube is connected to the cavity, which can ensure that the immersion oil in the pipette can be stably and quantitatively squeezed into the cavity. The fixed shell and the rotating shell are rotatably connected by the torsion shaft, so that the device can be flexibly clamped on the oil mirror.

[0007] Furthermore, a first anti-skid pad and a second anti-skid pad are respectively attached to the inner walls of the fixed shell and the rotating shell, and the first anti-skid pad and the second anti-skid pad are both made of rubber.

[0008] By adopting the above technical solution, the first anti-skid pad and the second anti-skid pad are respectively adhered to the inner walls of the fixed shell and the rotating shell, thereby increasing the friction between the device and the oil mirror and preventing the device from slipping during use.

[0009] Furthermore, a sealing sheet is provided between the fixed shell and the rotating shell to prevent leakage.

[0010] By adopting the above technical solution, a sealing sheet for preventing leakage is arranged between the fixed shell and the rotating shell, which effectively prevents the immersion oil from leaking out during use, thereby ensuring the accuracy of oil dripping and the clarity of observation.

[0011] Furthermore, an arc-shaped piece is fixedly connected to the back of the fixed shell, and a connecting rod for reinforcement is clamped on the back of the arc-shaped piece through a dovetail groove.

[0012] By adopting the above technical solution, the back of the fixed shell is fixedly connected with the arc-shaped piece, which provides a stable connection basis for the connecting rod.

[0013] Furthermore, one end of the connecting rod is fixedly connected to the pipette, and the connecting rod is made of rubber.

[0014] By adopting the above technical solution, one end of the connecting rod is fixedly connected to the pipette, thereby ensuring the stability of the pipette during use.

[0015] Furthermore, the bottoms of the fixed shell and the rotating shell are both made of transparent material.

[0016] By adopting the above technical solution, the bottoms of the fixed shell and the rotating shell are designed to be made of transparent materials, so that the user can clearly observe the oil dripping process.

[0017] Furthermore, a rubber pad for preventing the cover glass from being crushed is fixedly connected to the bottom of the fixed shell and the rotating shell, and the rubber pad is made of a transparent material.

[0018] By adopting the above technical solution, the bottoms of the fixed shell and the rotating shell are fixedly connected with rubber pads for preventing the cover glass from being crushed, which effectively reduces the pressure of the device on the glass and avoids the risk of the glass being crushed during use.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model realizes accurate absorption and quantitative dripping of immersion oil by setting a pipette, a fixed shell and a rotating shell, thereby improving the clarity of microscope observation. The components such as the anti-slip pad and the sealing sheet enhance the stability and sealing of the device, ensuring that the oil droplets will not leak, making the device more practical and reliable, and solving the technical problem that the amount of oil cannot be accurately controlled when dripping oil on a slide;

[0021] 2. The utility model provides a rubber pad, which can effectively reduce the pressure on the glass slide when the lens barrel descends so that the bottom of the fixed shell and the rotating shell contact the glass slide, avoiding the risk of the glass slide being crushed during use, thereby protecting the integrity of the glass slide and improving the safety and reliability of use.
