Description

Technical Field

[0001] This utility model belongs to the technical field of flatbed marking auxiliary tools, specifically relating to a flatbed marking adjustment device. Background Technology

[0002] Streaking is a widely used technique for microbial detection. Its principle is to disperse microorganisms by streaking them onto the surface of a solid culture medium under aseptic conditions, forming individual colonies for observation and identification.

[0003] Currently, when performing streak plating, operators need to hold the petri dish in one hand and the inoculation loop for streak plating in the other. Since streak plating is performed many times a day, holding the petri dish with culture medium for a long time can easily cause hand fatigue. At the same time, the position of the petri dish needs to be adjusted according to the streak plating needs, which further increases the burden on the operator's hands and increases the risk of the petri dish falling. In addition, holding the petri dish by hand can easily cause accidental contact with the inner culture medium, resulting in contamination. Therefore, a streak plating adjustment device is needed to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a flat plate scribing adjustment device, which features the advantages of not requiring the petri dish to be held by hand, convenient and easy operation, and strong practicality.

The arc-shaped sleeve 32 is fitted onto the outside of the positioning ball 22, and the size of the positioning ball 22 is adapted to the inner size of the arc-shaped sleeve 32, so that the conical cylinder 3 can rotate outside the positioning ball 22. See attached drawing for details. Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5 A pressing screw 33 is threaded onto the arc-shaped sleeve 32. A threaded hole 321 is provided on the inner wall of the arc-shaped sleeve 32, penetrating the sleeve. The pressing screw 33 is threaded onto the inner side of the threaded hole 321. One end of the pressing screw 33 is located on one side of the positioning ball 22 and can be pressed against the outer wall of the positioning ball 22. A friction pad 333 is fixed to one end of the pressing screw 33, located on one side of the positioning ball 22, which can more stably press against the positioning ball 22. A support is inserted into the inner side of the conical cylinder 3. The culture dish 4 is located above the partition 31. The inner side of the culture dish 4 is equipped with a plate culture medium 5. During subsequent streaking, the inoculation loop is placed on the plate culture medium 5. This scheme supports the culture medium through the base plate 1, the upright rod 2 and the conical cylinder 3, so that the operator does not need to hold the culture medium at all times when streaking, which is not easy to contaminate the culture medium. The position of the entire tool can be adjusted by rotating the upright rod 2, which saves effort. At the same time, the conical cylinder 3 and the culture dish 4 can be easily fixed at different angles to facilitate streaking.

[0023] Reference Figure 5 As shown, specifically, a rotating plate 331 is fixed to one end of the extrusion screw 33. The outer wall of the rotating plate 331 is provided with an arc-shaped groove 332. The arc-shaped groove 332 allows the operator to rotate the screw more conveniently and effortlessly without the need for additional tools, thus improving the ease of operation.

[0024] Reference Figure 2 and Figure 4 As shown, specifically, a first elastic rod 34 is fixed to the upper inner wall of the conical cylinder 3. Multiple first elastic rods 34 are provided, and a first pressing plate 35 is fixed to one end of each first elastic rod 34. The first pressing plate 35 adheres to the outer wall of the culture dish 4. During installation, the culture dish 4 is pressed down, causing the pressing plate to press against the outer wall of the culture dish 4. A second elastic rod 36 is fixed to the inner wall of the conical cylinder 3, and a second pressing plate 37 is fixed to one end of each second elastic rod 36. The second elastic rod 36 and the second pressing plate 37 are located above the partition plate 31. Multiple second elastic rods 36 and the second pressing plate 37 are provided. This solution installs the culture dish 4 using elastic pressing, ensuring stable installation. Disassembly and assembly are convenient; the culture dish 4 can be removed by inserting a finger through the gap between adjacent elastic rods. Furthermore, the two sets of elastic rods and pressing plates, located at different depths inside the conical cylinder 3, facilitate installation operations for different types of culture dishes 4, making it highly practical.

[0025] Example 2

[0026] In another embodiment of this solution, refer to Figure 2 and Figure 3 As shown, specifically, a thin rod 21 is fixedly connected to the upper end of the upright rod 2, and a positioning ball 22 is fixed to the top of the thin rod 21. By connecting the positioning ball 22 to the thin rod 21, the conical cylinder 3 can rotate a larger range outside the positioning ball 22, which makes it convenient for the operator to adjust the conical cylinder 3 and the petri dish 4 to a suitable angle for marking operations according to the needs of the operator.

[0027] The working principle and usage process of this utility model are as follows: When performing streak plating, the operator inserts the culture dish 4 containing the culture medium 5 into the inner side of the upper end of the conical cylinder 3. The culture dish 4 is then tightened and fixed by the elastic rod and the compression plate. Subsequently, the operator rotates the conical cylinder 3 outside the positioning ball 22 through the arc sleeve 32. After rotating to a suitable angle, the operator screws the compression screw 33 on the outside of the arc sleeve 32 from the bottom of the conical cylinder 3 to tighten and fix the conical cylinder 3 outside the positioning ball 22. It is supported by the base plate 1 and the upright 2. Then, the operator can hold the inoculation ring to perform streak plating. During the operation, the operator does not need to hold the culture dish 4 at all times, which saves effort.
