Description

Technical Field

[0001] The utility model relates to the technical field of biological culture, in particular to a bracket for biological culture. Background Art

[0002] Biological culture racks are devices used in biological laboratories to support and hold culture vessels. These racks usually have a well-designed structure to provide sufficient support and space to ensure stability and operability during biological culture.

[0003] Biological culture racks are generally equipped with a heating function, but the biological culture racks in the prior art usually directly heat the tube wall of the test tube. This heating method causes the liquid in the test tube to be heated unevenly, that is, the liquid close to the tube wall of the test tube can be fully heated, while the liquid in the middle cannot be heated evenly. The uneven heating will cause a temperature gradient in the liquid in the test tube, that is, the temperature in the middle of the test tube is lower, while the temperature of the liquid close to the tube wall is higher. This temperature gradient may affect the results of the biological culture experiment, especially for experiments that require precise temperature control, which will bring inconvenience to the use of the biological culture rack.

[0004] Therefore, it is necessary to design a biological culture bracket to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a bracket for biological culture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A biological culture bracket comprises a base, on which a plurality of test tubes are arranged, characterized in that two connecting rods are fixed to the base, an annular tube is commonly fixed to one end of the two connecting rods away from the base, a heating component is arranged on each of the test tubes, a plurality of jet components are arranged on the annular tube, and a heat source and an air source are installed on the base.

[0008] As a preferred technical solution of the utility model, the heating assembly includes an outer tube and an inner tube, the outer tube is fixedly wrapped around the test tube, the inner tube is placed inside the outer tube, and the two ends of the inner tube are fixedly connected to the two ends of the outer tube, and one end of the inner tube is connected to the annular tube.

[0009] As a preferred technical solution of the utility model, the jet assembly includes a jet tube and a plurality of jet holes, the jet tube is fixed on the annular tube, and the jet tube and the annular tube are connected, the jet tube extends to the interior of the test tube, and the plurality of jet holes are opened on the jet tube.

[0010] As a preferred technical solution of the utility model, the shape of the inner tube is matched with the shape of the outer tube, and both the inner tube and the outer tube are in a spiral structure.

[0011] As a preferred technical solution of the utility model, the plurality of air injection holes on each of the air injection pipes are evenly distributed.

[0012] As a preferred technical solution of the utility model, the outer surface of the outer tube and the outer surface of the test tube are in contact with each other.

[0013] The utility model has the following beneficial effects:

[0014] The bracket integrates a heat source and an air source. The heat can be pumped into the inner part of the outer tube through the operation of the air source. This design causes the outer tube to heat up, thereby directly heating the tube wall of the test tube, thereby achieving effective heating of the liquid in the test tube. The heating of the outer tube can not only directly heat the test tube, but also heat the inner tube and the gas flowing in the inner tube. This multi-level heat transfer method improves the heating efficiency and ensures that the liquid in the test tube is fully heated. The gas passing through the inner tube is ejected through the jet holes on the jet tubes and enters the liquid in the test tube to form bubbles. This bubble can make the liquid churn and achieve a stirring effect, which helps to maintain a uniform temperature distribution of the liquid. The heated gas not only forms bubbles through the jet holes, but also heats the liquid from the inside. This design ensures that the liquid is fully heated and improves the heating effect. It is suitable for experimental scenarios that require temperature control, such as biological culture. In summary, the bracket design comprehensively utilizes heat sources and gas sources, and through multi-level heat transfer and gas circulation, it achieves efficient heating and stirring of the liquid in the test tube, providing reliable temperature control and mixing effects for experiments such as biological culture.

The jet tube 7 is fixed on the annular tube 6, and the jet tube 7 is connected to the annular tube 6. The jet tube 7 extends to the inside of the test tube 2. The plurality of jet holes 8 are all provided on the jet tube 7. After passing through the inner tube 5, the gas enters the annular tube 6 and is ejected through the plurality of jet holes 8 on the plurality of jet tubes 7. The plurality of jet tubes 7 extend into the plurality of test tubes 2 respectively and are immersed in the liquid in the test tubes 2. In this way, the heated gas ejected from the plurality of jet holes 8 can form bubbles in the liquid in the test tube 2, causing the liquid to churn, thereby stirring the liquid. In addition, the heated gas can also heat the liquid from the inside of the liquid, so that the liquid can be fully heated, thereby ensuring the heating effect of the device on the liquid.

When the gas source 10 is in operation, the heat can be pumped into the interior of the plurality of outer tubes 4, so that the plurality of outer tubes 4 are heated and heated. When the outer tubes 4 are heated and heated, the tube wall of the test tube 2 can be directly heated, thereby heating the liquid in the test tube 2. When the gas source 10 is in operation, the gas can be pumped into the plurality of inner tubes 5. When the heat source 9 in the outer tube 4 heats the test tube 2, the inner tube 5 and the gas flowing in the inner tube 5 can also be heated. Furthermore, the gas will enter the annular tube 6 after passing through the inner tube 5, and will be ejected through the plurality of jet holes 8 on the plurality of jet tubes 7.
