[0002] A heat flow meter is an instrument used to measure heat flux density, widely applied in thermal research, building energy conservation, and materials testing. Its main function is to accurately calculate the heat flow to an object's surface by sensing heat transfer through sensors. Heat flow meters provide real-time data, helping engineers and researchers analyze heat exchange processes such as conduction, convection, and radiation, thereby optimizing designs and improving energy efficiency. Furthermore, it can be used to monitor and evaluate the performance of insulation materials.

[0003] In the prior art, some heat flow meters have poor airtightness when transmitting gas, which can lead to gas leakage, affecting the stability of gas flow rate and velocity, resulting in inaccurate measurement data. Gas leakage can also pollute the external environment, affecting the safety and reliability of the experiment. Poor airtightness can also damage the internal components of the heat flow meter, thereby affecting the long-term stability and service life of the instrument. To address these issues, a universal conversion connection mechanism for the gas outlet end of a heat flow meter is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 2 and Figure 4 This utility model provides an embodiment of a universal conversion connection mechanism for the outlet end of a heat flow meter, comprising a cross tube 1, with fixing rings 2 fixedly connected to each of the four corners of the cross tube 1, the cross tube 1 fixing the position of the fixing rings 2. A fixing tube 11 is detachably connected inside the fixing rings 2, the fixing rings 2 fixing the position of the fixing tube 11. A second spring 12 is fixedly connected to the inner wall of the fixing tube 11, the fixing tube 11 fixing the position of the second spring 12. The other end of the second spring 12 is fixedly connected to the outside of a solid ball 13; pushing the solid ball 13 compresses the second spring 12.

[0033] The solid ball 13 is externally slidably connected to the inner wall of the limiting tube 14. The limiting tube 14 supports and fixes the position of the solid ball 13, allowing it to slide freely within the inner wall of the limiting tube 14. The solid ball 13 is slidably connected to the inner wall of the fixing tube 11, supporting and fixing its position. The limiting tube 14 is externally fixedly connected to the fixing tube 11, fixing its position. A threaded tube 15 is externally threaded to the limiting tube 14. Rotating the threaded tube 15 allows it to move closer to or further away from the limiting tube 14, thus enabling the disassembly and installation of the pipe.

[0034] A sliding tube 17 is fixedly connected to the inner wall of the threaded tube 15. The threaded tube 15 fixes the position of the sliding tube 17, and the movement of the threaded tube 15 towards or away from the sliding tube 17 causes it to move closer or further away. The outer side of the sliding tube 17 is detachably connected to the inner wall of the limiting tube 14, which provides space for the sliding tube 17 to move. An vent pipe 16 is fixedly connected to the inner wall of the threaded tube 15, and the movement of the threaded tube 15 causes the vent pipe 16 to move accordingly.

[0035] Reference Figure 1 and Figure 3 Both fixed rings 2 have detachable anti-leak plugs 5 on their inner walls. During the universal rotation, only two of the four fixed rings 2 are used for gas connection; the other two are plugged with anti-leak plugs 5 to prevent leakage. Both anti-leak plugs 5 are externally fixed with cross blocks 18, making disassembly of the anti-leak plugs 5 easier. Two fixed rings 2 are externally rotatably connected with rotating rings 3, which limit the position of the fixed rings 2 during rotational direction changes. Two additional fixed rings 2 are externally rotatably connected with rotating rings 4, which also limit the position of the fixed rings 2 during rotational direction changes. The rotating rings 3 have internal slots 19 to ensure smooth connection when changing direction with the used pipe.

[0036] The rotating ring 4 has a slot inside to ensure smooth connection when changing direction or using the pipe opening. The fixed pipe 11 is detachably connected to the inner wall of the slot and the inner wall of the slot opening 19. The fixed pipe 11 and its connecting part are a structure to prevent leakage in the air outlet, indicating that the leakage-proof structure can be freely connected and disassembled through the slot opening 19 and the slot. The air inlet structure of the connecting pipe 6 and its connecting part is also detachably connected to the inner wall of the slot opening 19 and the slot, which facilitates connection and disassembly.

[0037] Reference Figure 3 and Figure 5The fixed ring 2 is detachably connected to an air intake assembly to accommodate the air inlet. The air intake assembly includes a connecting pipe 6, which is detachably connected to the inner wall of the fixed ring 2, fixing the position of the connecting pipe 6. A spring 7 is fixedly connected to the inner wall of the connecting pipe 6, fixing the position of the connecting pipe 6 relative to the spring 7. A push pipe 8 is slidably connected to the inner wall of the connecting pipe 6, limiting the position of the push pipe 8 and providing a space for movement. The other end of the spring 7 is fixedly connected to the outside of the push pipe 8, allowing the spring 7 to extend as the push pipe 8 moves outward. A rotating pipe 9 is detachably connected to the outside of the push pipe 8, limiting the position of the push pipe 8. The rotating pipe 9 is rotatably connected to the outside of a rotating ring 3, fixing the position of the rotating pipe 9. An air intake pipe 10 is rotatably connected to the outside of the rotating pipe 9, fixing the position of the rotating pipe 10.

[0038] Working Principle: In use, the inlet pipe 10 serves as the outlet of the heat flow meter. For the unused ends of the pipes, rotate the two cross blocks 18. This rotation of the cross blocks 18 causes the two leak-proof plugs 5 to rotate, sealing the pipe ends and preventing any impact on the airtightness of subsequent gas transfer. Connect the two pipes to be used to a flexible hose. Connect one end of the hose to the push tube 8, and fix the position of the connecting tube 6 relative to the pipe opening. Pulling the hose causes the push tube 8 to contract. The contraction of the push tube 8 compresses the spring 7. After the external force is removed, the spring 7 returns to its original position, causing the push tube 8 to extend into the inner wall of the rotating tube 9. This makes the gas transmission path more precise, improving measurement accuracy and response speed, reducing airflow resistance, and obtaining more accurate heat flow data. This optimization helps in real-time monitoring and evaluation of the heat exchange process, improving experimental efficiency.

[0039] Rotating the rotating rings 3 and 4 allows the position of the cross tube 1 to be defined, ensuring that the four ends of the cross tube 1 are aligned with the desired configuration. The fixed tube 11 is installed at the other end. Rotating the threaded tube 15 causes the sliding tube 17 to move, pushing the solid ball 13 and creating a gas channel within the limiting tube 14 and the sliding tube 17. This allows gas to pass through. When the threaded tube 15 spirals away, the spring 12 compressing the solid ball 13 returns it to its original position, blocking the opening of the limiting tube 14. This provides a gas seal when no gas is being transmitted, effectively preventing gas leakage, reducing environmental pollution and errors, and ensuring measurement accuracy. Furthermore, this sealing protection extends the instrument's lifespan and maintains the integrity of internal components.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
