Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant microtube thermal measurement technology, and in particular to a constant power driven corrosion-resistant microtube thermal measurement device. Background Technology

[0002] Constant power driven corrosion-resistant microtube thermal measurement devices are precision instruments widely used in chemical, biomedical, and materials science fields. They are mainly used to measure the thermal conductivity characteristics of microscale fluids in high-temperature or corrosive environments. With the rapid development of microfluidics technology, higher requirements have been placed on the accuracy, stability, and environmental adaptability of microtube thermal measurement devices. Traditional devices usually adopt fixed microtube structures, which are difficult to adapt to the needs of different experimental scenarios. Their limitations are particularly prominent in experiments that require frequent replacement of microtubes or adjustment of measurement parameters.

[0003] In the existing technology, microtube thermal measurement devices mostly use mechanical structures that are welded or threaded to connect the microtube to the measuring instrument. The microtube is usually fixed to the connection port by a sealing ring or adhesive to ensure sealing and stability.

[0004] The main problem with existing technologies is that the microtube replacement process is cumbersome, which seriously affects experimental efficiency. Since microtubes are usually fixed or rely on adhesive sealing, replacement requires disassembling multiple parts or even resealing, which is not only time-consuming and labor-intensive, but can also lead to seal failure or microtube damage due to improper operation. This problem is particularly prominent in experiments that require frequent switching of microtubes of different specifications. For example, when comparing the thermal conductivity of microtubes of different materials, traditional devices cannot meet the need for rapid replacement, thus limiting the flexibility of experiments and the acquisition of diverse data. To address this issue, a constant power driven corrosion-resistant microtube thermal measurement device is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A constant power driven corrosion-resistant microtube thermal measurement device includes a measuring instrument, a controller is provided on the side wall of the measuring instrument, a connecting pipe is fixedly connected to the side wall of the measuring instrument, a microtube body is slidably connected inside the connecting pipe, a slot is opened inside the microtube body, and a disassembly component is provided inside the connecting pipe.

The sliding frame causes the triangular locking block to disengage from the second locking slot. Subsequently, the outer shell slides within the measuring instrument to achieve disassembly, thereby exposing the internal components of the device for easy maintenance.

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 1 - Figure 5This utility model provides an embodiment of a constant power driven corrosion-resistant microtube thermal measurement device, including a measuring instrument 1. The measuring instrument 1 has a controller 2 on its side wall for controlling constant power output and monitoring temperature data. A connecting pipe 3 is fixedly connected to the side wall of the measuring instrument 1, serving as a mounting base for the microtube body 4 and providing a fluid channel. The microtube body 4 is slidably connected inside the connecting pipe 3 and is made of corrosion-resistant material to adapt to different experimental environments. The microtube body 4 has a slot 8 inside for cooperating with a trapezoidal locking post 10 to achieve quick fixation. The connecting pipe 3 has a disassembly assembly inside for easy replacement of the microtube body 4.

[0033] The disassembly assembly includes a trapezoidal locking post 10, which is slidably connected inside the connecting tube 3. Its inclined surface design enables a self-locking function. The trapezoidal locking post 10 engages with the slot 8 to ensure a stable connection of the microtube body 4. A fixing ring 5 is fixedly connected to the outer wall of the connecting tube 3 to limit the movement range of the sliding sleeve 6. The sliding sleeve 6 is slidably connected to the outer wall of the connecting tube 3, allowing manual control of the displacement of the trapezoidal locking post 10. A spring 7 is fitted onto the outer wall of the connecting tube 3, providing a restoring force to automatically return the sliding sleeve 6 to its original position. One end of the spring 7 is fixedly connected to the side wall of the fixing ring 5, and the other end is fixedly connected to the inner wall of the sliding sleeve 6, ensuring effective transmission of elastic force. A groove 11 is provided inside the sliding sleeve 6 to provide space for the trapezoidal locking post 10 to achieve the unlocking function. The measuring instrument 1 is equipped with a buckle assembly for quick disassembly and maintenance of the outer casing 12.

[0034] Reference Figure 1 - Figure 5The latching assembly includes a sliding frame 14, which is slidably connected inside the measuring instrument 1 to achieve quick locking and releasing of the outer casing 12. A connecting block 16 is fixedly connected to the top of the sliding frame 14 as an intermediary component for force transmission. A triangular locking block 17 is fixedly connected to the top of the connecting block 16, and its inclined structure facilitates engagement and disengagement with the second locking slot 18. The outer casing 12 is slidably connected inside the measuring instrument 1 to protect internal precision components. The outer casing 12 has a second locking slot 18 inside, which cooperates with the triangular locking block 17 to form a stable locking structure. The second locking slot 18 engages with the triangular locking block 17 to ensure the secure locking of the outer casing 12. The measuring instrument 1 has a fixed frame 15 fixedly connected to its inner wall to provide precise guidance for the sliding frame 14. The sliding frame 14 is slidably connected inside the fixed frame 15 to ensure the straightness of the movement trajectory. The sliding frame 14 has a pressing handle 13 on its side wall for manual operation to unlock. The pressing handle 13 is fixedly connected to the side wall of the sliding frame 14 to ensure effective transmission of operating force. The fixed frame 15 has a second spring 9 inside to provide an automatic reset function. One end of the second spring 9 is fixedly connected to the inner wall of the fixed frame 15, and the other end of the second spring 9 is fixedly connected to the inner wall of the sliding frame 14 to ensure reliable elastic restoring force.

[0035] Working principle: When the microtube body 4 needs to be replaced, the sliding sleeve 6 is pushed to slide along the outer wall of the connecting tube 3. The sliding sleeve 6 compresses the spring 7 to store force, and at the same time, the sliding sleeve 6 drives the internal groove 11 to move. The movement of the groove 11 causes the trapezoidal locking post 10 to lose its limit and slide along the inside of the connecting tube 3. The trapezoidal locking post 10 slides out of the locking groove 8 of the microtube body 4 to release the lock. Then the microtube body 4 can be pulled out from the inside of the connecting tube 3 to complete the disassembly. When installing the new microtube body 4, the sliding sleeve 6 is released, the spring 7 returns to its original position and pushes the sliding sleeve 6 back. After the groove 11 returns to its original position, the trapezoidal locking post 10 re-locks into the new microtube body 4. The slot 18 is used for fixing. When it is necessary to repair the internal components of the measuring instrument 1, the sliding frame 14 is slid inside the fixed frame 15 by pressing the pressing handle 13. The sliding frame 14 slides and compresses the second spring 9 to store force. At the same time, the sliding frame 14 drives the connecting block 16 to move. The connecting block 16 drives the triangular locking block 17 to slide out of the slot 18 of the outer shell 12 and release the locking. Then the outer shell 12 can be pulled out from the inside of the measuring instrument 1. After the repair is completed, the pressing handle 13 is released, the second spring 9 returns to its original position and pushes the sliding frame 14 back. The triangular locking block 17 returns to its original position with the sliding frame 14 and re-locks into the slot 18 to fix the outer shell 12.
