DETAILED DESCRIPTION
[0017] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.
[0018] like Figure 1-4 As shown, a laboratory medicine spoon includes a spoon body 1, which includes a spoon handle 11 and a spoon head 12 connected to the end of the spoon handle 11. A measuring rod 2 is movably installed in the spoon body 1 for adjusting the effective capacity of the spoon head 12. The spoon body 1 is also equipped with a flattening paddle 5 for scraping the material loaded on the spoon head 12.
[0019] The sampling amount of the medicine spoon provided by the present invention is controllable. Through the cooperation of the adjusting rod 2 and the measuring line 24, the experimenter can accurately adjust the effective capacity of the spoon head 12 according to the experimental requirements to ensure that the amount of sampling each time is consistent. This is crucial for the accuracy and repeatability of the experiment, avoids the waste of materials caused by excessive material taking by traditional medicine spoons, simplifies the tedious process of repeatedly taking small amounts of samples, and improves the efficiency of the experimental process. In addition, the present invention integrates a flat material paddle 5 on the spoon handle 11. Through the swing structure 14 and the torsion spring 4 of the flat material paddle 5, the experimenter can easily scrape the material flat without the need for additional tools. The operation is simple and quick, which improves the convenience of the experiment. In summary, the medicine spoon provided by the present invention not only solves the shortcomings of traditional medicine spoons in accurate sampling, but also greatly improves the accuracy, efficiency and convenience of experimental operations through the integration of a series of innovative structures.
[0020] like Figure 1-3 As shown, the spoon handle 11 is provided with an adjustment hole 15, which extends into the spoon head 12. The adjusting rod 2 is movably arranged in the adjustment hole 15, and a measuring line 24 is provided on the adjusting rod 2. In addition to being used to adjust the effective capacity inside the spoon head 12, the adjusting rod 2 is also designed to extend the spoon handle 11. This feature has significant application advantages in sampling bottles of different depths. Specifically, in a deep-mouth sampling bottle, the adjusting rod 2 can enable the spoon head 12 to penetrate deep into the bottom of the container, ensuring that the medicine spoon can reach the material at the very bottom of the container, which is crucial for obtaining uniform and undisturbed samples, especially in experimental scenarios where precipitation or sediment needs to be extracted from the bottom.
[0021] like Figure 2 and Figure 3 As shown, a limiting structure 13 is provided on the spoon handle 11, and a limiting bolt 3 is threadedly connected to the limiting structure 13. A threaded structure 22 is provided in the middle of the adjusting rod 2, and the end of the limiting bolt 3 cooperates with the threaded structure 22. Specifically, the spoon handle 11 is a rotating body structure, and the side away from the spoon head 12 can be set as a texture structure to enhance the gripping effect. The limiting structure 13 is arranged on the side close to the spoon handle 11. The limiting structure 13 is used to load and connect the limiting bolt 3. The limiting structure 13 is formed by milling a groove on the spoon handle 11 and then opening a threaded hole, and the threaded hole passes through the adjusting through-hole 15. The limiting structure 13 is symmetrically arranged on the spoon handle 11, and at least two threaded holes are opened in each groove. In particular, in order to enhance the matching degree between the limiting bolt 3 and the threaded structure 22, the end of the limiting bolt 3 can be ground into a tooth-like structure. The limiting structure 13 is selected to install the limiting bolt 3 and cooperate with the threaded structure 22 to form a threaded connection because the cost of designing a thread in the adjustment through-hole 15 is high, and the torque used to rotate the adjusting rod 2 is large, which is not light enough.
[0022] like Figure 2As shown, the end of the measuring rod 2 extending into the spoon head 12 is a ball-shaped structure 21, while the end away from the spoon head 12 is a tail hammer structure 23. A measuring line 24 is located on the side near the tail hammer structure 23. The design of the measuring rod 2 in a laboratory medicine spoon is very ingenious, with different structures at each end serving specific functions to ensure accurate and smooth experimental operation. The ball-shaped structure 21, located at the end of the measuring rod 2 extending into the spoon head 12, primarily functions to adjust the effective capacity of the spoon head 12 while preventing powdered materials from clinging. The spherical design reduces the surface area in contact with the material, helping to reduce powder adhesion, making pouring the material smoother and avoiding residue, ensuring the accurate amount of sample is measured. The tail hammer structure 23, located at the end of the measuring rod 2 away from the spoon head 12, is equipped with a weighted tail. Its main function is to crush or compact the material during the measuring process. When encountering lumps or agglomerated materials, the tail hammer structure 23 can help break them up, ensuring even distribution and easier scraping. This is particularly useful for measuring solid particles or samples that easily form clumps, ensuring the accuracy and consistency of the sample volume.
[0023] like Figure 1 and Figure 2 As shown, the spoon handle 11 is provided with a swinging structure 14, to which the material-leveling paddle 5 is connected via a torsion spring 4 and screws. Specifically, the swinging structure 14 is an annular protrusion on the spoon handle 11. To mount the material-leveling paddle 5, a flat surface is milled on the annular protrusion and a threaded hole is drilled in the flat surface. The material-leveling paddle 5 is screwed into the threaded hole. One end of the torsion spring 4 is connected to the material-leveling paddle 5, and the other end is connected to the swinging structure 14. The material-leveling paddle 5 plays a crucial role in laboratory medicine spoons, primarily ensuring a smooth surface for the material loaded on the spoon head. The material-leveling paddle 5 is a hard, thin structure, with a slender end for scraping the material and a circular end for manual shifting. The material-leveling paddle 5 is able to swing flexibly with the help of the torsion spring 4. When the medicine spoon is full of material, the user can gently move the material-leveling paddle, using its edge to scrape the material within the spoon head, preventing it from overflowing the spoon head or piling unevenly, and ensuring a consistent amount of material for each sampling.
[0024] The use of a laboratory medicine spoon demonstrates the efficiency, precision, and convenience of its innovative design. The following details how to use the medicine spoon for precise sampling, including key steps such as adjusting the metering rod 2 to control the amount of material removed by the spoon head 12, crushing the material with the tail hammer structure 23, and leveling the material with the leveling paddle 5.
[0025] 1. Adjust the amount of material taken by the spoon head 12 by adjusting the amount of material taken by the spoon head 12.
[0026] First, confirm the sampling volume required for the experiment and set the target capacity by referring to the measuring line 24 on the measuring rod 2. Rotate the measuring rod 2, and the threaded structure 22 thereon interacts with the limit bolt 3 installed in the limit structure 13 to adjust the position of the measuring rod 2 in the spoon head 12, thereby changing the effective capacity of the spoon head 12. When the measuring rod 2 moves to the appropriate position, the material can be taken. If the medicine spoon is in this quantitative working state for a long time, the limit bolt 3 can be adjusted so that it is stuck in the corresponding threaded structure 22 to ensure that the measuring rod 2 is fixed in position to achieve the preset sampling volume.
[0027] 2. The tail hammer structure 23 crushes the material.
[0028] When sampling, if you encounter agglomerated or agglomerated materials, you can use the tail hammer structure 23 at the end of the measuring rod 2 far from the spoon head 12. The tail hammer structure 23 is gently tapped on the agglomerated material, and the material is crushed or compacted with the help of its weighted tail to disperse the material and ensure that the material can be evenly distributed.
[0029] 3. The flat material pick 5 flattens the material.
[0030] When the spoon head 12 is filled with material, the material leveling paddle 5 is operated via the swinging structure 14 on the spoon handle 11. The paddle 5 is moved, and its edge scrapes the material inside the spoon head 12, ensuring a smooth surface and preventing it from overflowing the edge of the spoon head 12 or from being unevenly accumulated. This ensures that the amount of material sampled is consistent each time. The elastic action of the torsion spring 4 ensures that the paddle 5 automatically returns to its original position after use, ready for the next scraping operation.
[0031] The use of the laboratory medicine spoon fully demonstrates the advantages of its innovative design. From the precise adjustment of the measuring rod 2, to the material dispersion of the tail hammer structure 23, to the material leveling of the material leveling paddle 5, each step is designed to improve experimental accuracy and repeatability, reduce material waste, simplify the experimental process, and improve experimental efficiency. These designs ensure the accuracy, efficiency, and convenience of experimental operations, greatly optimizing the experimental process.
