[0001] The invention relates to the field of immunology experiment test tubes, in particular to a chemical test tube placement rack based on immunology experiments. Background Art

[0002] Immunology is a biomedical science that studies the immune response of organisms to antigenic substances and its methods. Immune response is the body's reaction to antigenic stimulation, and is also a biological process of identifying and eliminating antigenic substances.

[0003] Chemistry is a type of natural science that studies the properties, composition, structure and laws of change of substances at the molecular and atomic levels. In chemistry teaching, test tubes are often needed, and test tube racks are needed to place test tubes.

[0004] At present, the test tube rack used in immunology experiments is unstable, and it is difficult to protect the test tubes. The test tubes are easily damaged by the outside world. Therefore, we propose a chemical test tube rack based on immunology experiments. Summary of the invention

[0008] Preferably, the buffer structure includes a rubber pad and a buffer spring, the rubber pad is slidably connected to the bottom of the groove, the number of the rubber pads is several, the bottom of the buffer spring is fixedly connected to the bottom of the groove, and the top of the buffer spring is fixedly connected to the rubber pad.

[0009] Preferably, the temperature control structure includes a single-chip microcomputer control board, a temperature display, a temperature control knob, a heating plate and a temperature sensor. The single-chip microcomputer control board is fixedly mounted inside the test tube rack base, the temperature display is fixedly mounted on the outer wall of the test tube rack, the temperature control knob is rotatably connected to the outer wall of the temperature display, the heating plate is fixedly mounted inside the test tube rack, the number of the heating plates is several, the temperature sensor is fixedly mounted inside the test tube rack, the temperature display is electrically connected to the single-chip microcomputer control board, the temperature sensor is electrically connected to the single-chip microcomputer control board, and the single-chip microcomputer control board, as the core of the entire temperature control system, is responsible for receiving real-time temperature data from the temperature sensor and adjusting the power of the heating plate according to the set value of the temperature control knob to achieve precise temperature control.

[0010] The temperature sensor is like a keen detective, constantly monitoring the temperature changes inside the test tube rack. Once the temperature exceeds or falls below the set threshold, it will immediately pass this information to the microcontroller control board. The microcontroller control board will respond quickly based on this information and adjust the power of the heating plate to return the temperature to near the set value.

[0011] The temperature display is a bridge between the user and the temperature control system. It displays the current temperature value in real time, allowing the user to intuitively understand the temperature conditions in the test tube. At the same time, the user can also set the desired temperature value by rotating the temperature control knob to achieve precise temperature control.

[0012] Preferably, the test tube includes a wear-resistant surface layer, a scale bar and a shading sheet, the test tube is inserted into the inside of the groove, the size of the test tube is matched with the size of the test tube rack, the wear-resistant surface layer is fixedly connected to the surface of the test tube, the scale bar is fixedly connected to the surface of the test tube, the shading sheet is fixedly connected to the outer wall of the test tube, the shading sheet is opaque, and the design of the shading sheet is particularly unique, it fits tightly to the outer wall of the test tube, which not only ensures that the solution inside the test tube maintains its stability without being disturbed by external light, but also provides a clear observation space for the user.

[0013] The wear-resistant surface can effectively resist the scratches and abrasions that may occur during the experiment, ensuring that the test tube can maintain its original appearance and function for a long time. The scale bar design allows users to accurately read the amount of solution in the test tube, providing a strong guarantee for the accuracy of experimental data.

This design not only enhances the fixing stability of the test tube rack, but also improves the safety of operation.

[0015] As the core component of the fixed structure, the power and performance of the air pump directly affect the adsorption force of the fixed suction cup. We specially selected a high-efficiency air pump to ensure stable adsorption under various environmental conditions. The addition of a one-way valve further enhances the performance of the air inlet, effectively prevents gas backflow, and improves overall safety.

[0016] Preferably, the culture dish is fixedly mounted on the surface of the test tube rack base, the number of the culture dishes is two, and the transparent protective shell is movably connected to the surface of the culture dish.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention designs a highly integrated and multifunctional immunology experiment test tube placement rack, which greatly improves the efficiency and safety of laboratory work. First, through the cooperation of the photoelectric sensor taking and the photoelectric sensor holding in the test tube rack structure, as well as the coordinated work of the hydraulic rod and the protective clamp, the test tube is precisely controlled and protected during the taking and placing process, effectively avoiding damage or contamination of the test tube caused by human operating errors.

[0020] Secondly, the rubber pads and buffer springs in the buffer structure can effectively absorb external impacts, providing additional safety for the test tubes. This protective structure is particularly important in the event of accidental collisions or vibrations that are common in laboratories.

[0021] The temperature control structure can achieve precise control of the internal environment of the test tube through the synergistic effect of the single-chip control board, temperature display, temperature control knob, heating plate and temperature sensor, providing a stable temperature environment for immunology experiments and ensuring the accuracy and reliability of the experimental results.

The bottom of the buffer spring 32 is fixedly connected to the bottom of the groove 22, and the top of the buffer spring 32 is fixedly connected to the rubber pad 31.

[0041] The temperature control structure 4 includes a single-chip microcomputer control board 41, a temperature display 42, a temperature control knob 43, a heating plate 44 and a temperature sensor 45. The single-chip microcomputer control board 41 is fixedly installed inside the test tube rack base 1, the temperature display 42 is fixedly installed on the outer wall of the test tube rack 21, the temperature control knob 43 is rotatably connected to the outer wall of the temperature display 42, the heating plate 44 is fixedly installed inside the test tube rack 21, the number of the heating plates 44 is several, the temperature sensor 45 is fixedly installed inside the test tube rack 21, the temperature display 42 is electrically connected to the single-chip microcomputer control board 41, and the temperature sensor 45 is electrically connected to the single-chip microcomputer control board 41.

[0042] The test tube 5 includes a wear-resistant surface layer 51, a scale bar 52 and a shading sheet 53. The test tube 5 is inserted into the inside of the groove 22. The size of the test tube 5 is compatible with the size of the test tube rack 21. The wear-resistant surface layer 51 is fixedly connected to the surface of the test tube 5. The scale bar 52 is fixedly connected to the surface of the test tube 5. The shading sheet 53 is fixedly connected to the outer wall of the test tube 5. The shading sheet 53 is opaque.

[0043] The fixed structure 6 includes a fixed suction cup 61, an air channel 62, an air pump 63 and an air inlet 64. The fixed suction cup 61 is fixedly installed at the bottom of the test tube rack base 1. There are several fixed suction cups 61. The air channel 62 is connected between the fixed suction cups 61. The air pump 63 is fixedly installed on one side of the air channel 62. The air inlet 64 is fixedly installed on the top of the air channel 62. A one-way valve is arranged inside the air inlet 64.

[0044] The culture dish 7 is fixedly mounted on the surface of the test tube rack base 1 , the number of the culture dishes 7 is two, and the transparent protective shell 8 is movably connected to the surface of the culture dish 7 .

[0045] The receiving port of the photoelectric sensor 23 is set on the surface of the test tube rack 21, which can sense the passage of objects and control the hydraulic rod 25 to tighten. The receiving port of the photoelectric sensor 24 is set on one side of the groove 22, which can sense the passage of objects and control the hydraulic rod 25 to extend.

[0046] Embodiment 1:

[0047] When the experimenter needs to take the test tube 5, the hand passes over the surface of the test tube rack 21, and the photoelectric sensor 23 senses the passing of the object and immediately sends a signal to the single-chip control board 41. After receiving the signal, the single-chip control board 41 controls the hydraulic rod 25 to tighten, driving the protective clamp 26 to move inward, thereby loosening the clamp on the test tube 5. The experimenter can easily take the test tube 5 out of the groove 22 and conduct subsequent immunological experiments.

[0048] After the test tube 5 is taken away, the groove 22 inside the test tube rack 21 becomes empty. At this time, the photoelectric sensor 24 senses the state change of the groove 22 and also sends a signal to the single-chip control board 41. After receiving the signal, the single-chip control board 41 controls the hydraulic rod 25 to extend, driving the protective clamp 26 to move outward, restore to the initial clamping position, and wait for the next test tube 5 to be put in.

[0049] When the test tube 5 is placed in the groove 22, the test tube 5 can be effectively buffered and protected due to the presence of the rubber pad 31 and the buffer spring 32, thereby avoiding collision and damage during placement. At the same time, the sliding connection design of the rubber pad 31 makes the test tube 5 more stable in the groove 22 and less likely to shake.

[0050] During the immunology experiment, the experimental conditions inside the test tube 5 need to be precisely controlled. The single-chip control board 41 in the temperature control structure 4 can control the heating plate 44 to heat or stop heating according to the setting of the temperature control knob 43, thereby realizing precise control of the temperature inside the test tube 5. At the same time, the temperature sensor 45 monitors the temperature inside the test tube 5 in real time and transmits the data to the single-chip control board 41, forming a closed-loop control to ensure the stability of the temperature inside the test tube 5.

[0051] When the test tube rack base 1 needs to be fixed on the laboratory table, it can be operated through the fixing structure 6. Open the air inlet 64, start the air pump 63, and extract the air in the fixed suction cup 61 through the air channel 62, so that a negative pressure is formed inside the fixed suction cup 61, thereby firmly adsorbing the test tube rack base 1 on the laboratory table. After the experiment is over, turn off the air pump 63, open the air inlet 64, and the air inside the fixed suction cup 61 re-enters, and the test tube rack base 1 can be easily removed.

[0052] In addition, the culture dish 7 is used to store cells or microbial samples in immunology experiments, and the transparent protective shell 8 can protect the samples in the culture dish 7 from external contamination and interference. The movable connection design of the transparent protective shell 8 is convenient for the experimenter to open or close it at any time to observe the growth of the sample.

[0053] The entire chemical test tube placement rack based on immunology experiments has a reasonable design and complete functions, and can meet the placement, protection and temperature control requirements of test tubes 5, culture dishes 7 and other experimental equipment in immunology experiments, thereby improving experimental efficiency and accuracy.

The bottom of the buffer spring 32 is fixedly connected to the bottom of the groove 22. The top of the buffer spring 32 is fixedly connected to the rubber pad 31 to the test tube rack structure 2. This part is the core part for placing and clamping the test tube 5. The test tube rack structure 2 is very delicately designed.

In addition, the material of the test tube rack structure 2 is a special alloy that is corrosion-resistant and high-temperature resistant, ensuring that even in a long-term high-temperature and corrosive liquid environment, it can maintain good structural stability.
