Description

Technical Field

[0001] This utility model relates to the field of biological culture dish technology, and in particular to a biological experimental culture dish. Background Technology

[0002] Biological experiments are a key to exploring the mysteries of life. In the laboratory, researchers operate sophisticated instruments to observe the microscopic structure of cells, watching them operate like busy little factories, carrying out metabolic and division activities in an orderly manner. This reveals the mechanisms of biological growth and development. Biological experiments cover a variety of fields, from ecosystem simulation to gene editing, simulating the survival and reproduction of species in different ecological environments, using cutting-edge technologies to rewrite gene sequences, exploring changes in biological traits, opening up new paths for many industries such as medicine and agriculture, and promoting the progress of human society. Biological experimental petri dishes are usually made of transparent glass and plastic. The round body of the dish is like a small stage. On this stage, researchers inoculate microorganisms such as bacteria and fungi into them and add suitable culture media to observe their growth and reproduction characteristics and study their living habits. However, if they are not effectively fixed during use, it will affect the culture results.

[0003] Existing magnetic fixation mechanisms consist of magnets and fixing components, operating on the principle of magnetism. They have strong magnets built into their bottom and sides, and corresponding magnetic components on the experimental table or support. When a culture dish is placed on them, it is firmly attracted. This method not only provides good fixation but is also convenient to operate. In high-throughput experiments requiring frequent culture dish changes, it greatly improves efficiency, allowing researchers to conduct studies on biological samples within the culture dishes more smoothly. However, this fixation method is costly and not very secure, easily shifting out of position, causing the culture dish to fall or shake, affecting the culture results. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a biological experimental culture dish, which aims to improve the problem that the existing fixing method is not secure, is prone to deviation, and causes the culture dish to fall and shake, thus affecting the culture results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biological experimental culture dish, comprising an upper base plate, wherein a circular groove is formed near the center of the top of the upper base plate, and multiple limiting rings are fixedly connected to the periphery of the circular groove near the edge, the bottom of the limiting rings being fixedly connected to the top of the upper base plate near the center, and multiple fixing plates are fixedly connected to the left and right sides of the top of the upper base plate near the edge, wherein a square hole is formed at the upper right end of the fixing plate, a fixing block is fixedly connected to the top of the inner wall of the square hole, a spring is slidably connected to the top of the outer wall of the fixing block, a stop rod is slidably connected to the lower end of the outer wall of the fixing block, and multiple circular holes are formed at the left and right ends of the stop rod, the inner walls of the circular holes being slidably connected to the outer walls of the fixing blocks, and a vibration damping mechanism is provided at the bottom of the upper base plate, the vibration damping mechanism being used for buffering and vibration reduction.

[0006] As a further description of the above technical solution:

[0007] The vibration damping mechanism includes a sleeve, the top of which is fixedly connected to the bottom of the upper base plate near the middle. A circular hole is formed at the bottom of the inner wall of the sleeve. A connecting column is fixedly connected to the top of the inner wall of the circular hole. A spring is slidably connected to the top of the outer wall of the connecting column. A sliding column is fixedly connected to the bottom of the spring. The outer wall of the sliding column is slidably connected to the inner wall of the circular hole. A second sliding column is fixedly connected to the bottom of the sliding column.

[0008] As a further description of the above technical solution:

[0009] A temperature control console is fixedly connected to the right rear side of the top of the upper base plate, and the bottom of the temperature control console is fixedly connected to the top of the lower base plate.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the circular groove is slidably connected to a lower culture dish, and the outer wall of the lower culture dish is slidably connected to the inner wall of the limiting ring.

[0012] As a further description of the above technical solution:

[0013] The top of the lower culture dish is fixedly connected with an external thread, and the top of the external thread is threaded with a culture dish lid.

[0014] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] A display port is fixedly connected to the top left side of the upper base plate, and multiple support legs are fixedly connected to the bottom four sides of the upper base plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when it is necessary to install the culture dish, the culture dish lid is rotated into the lower culture dish through the external thread, and then the stop bar is pulled upward. At this time, the second circular hole on the stop bar will slide upward along the fixing block on the fixing plate. At this time, the stop bar will compress the spring and deform it. Then, the lower culture dish is placed in the circular groove in the upper base plate. At this time, the limiting ring will tightly lock the lower culture dish inside. At the same time, the stop bar is released, and the spring will return to its original state, driving the stop bar downward to lock above the culture dish lid. At this time, it can be cultured and observed, which provides more stable support for the culture dish and facilitates observation.

[0022] 2. In this utility model, when vibration occurs in the surrounding area, the lower base plate drives the second sliding column to vibrate, and the second sliding column drives the first sliding column to vibrate, so that the first sliding column will move up and down in the circular hole of the sleeve. At this time, the first sliding column will squeeze the connecting column and deform it, thus achieving the effect of vibration reduction. When the vibration is transmitted to the lower culture dish, it will be alleviated, thus achieving the effect of reducing the vibration in the surrounding area. Attached Figure Description

[0039] Working principle: When the petri dish needs to be installed, the petri dish cover 15 is rotated into the lower petri dish 12 through the external thread 13. Then, the stop rod 5 is pulled upward. At this time, the circular hole 6 on the stop rod 5 will slide upward along the fixing block 7 on the fixing plate 10. At this time, the stop rod 5 will compress the spring 8 to deform it. Then, the lower petri dish 12 is placed in the circular groove 4 in the upper base plate 1. At this time, the limiting ring 3 will tightly lock the lower petri dish 12 inside. At the same time, the stop rod 5 is released. At this time, the spring 8 will return to its original state, driving the stop rod 5 downward to lock above the petri dish cover 15. At this time, it can be used for culture and observation, which provides more stable support for the petri dish and facilitates observation.

[0040] When vibrations occur in the surrounding area, the lower base plate 16 drives the second sliding column 206 to vibrate, and the second sliding column 206 drives the first sliding column 205 to vibrate, causing the first sliding column 205 to move up and down in the circular hole 202 of the sleeve 201. At this time, the first sliding column 205 will compress the spring 204 on the connecting column 203, causing it to deform and achieving the effect of vibration reduction. When the vibration is transmitted to the lower culture dish 12, it will be alleviated, thus achieving the effect of reducing the vibration of the surrounding area.
