Description

Technical Field

[0001] This utility model relates to the field of thermocouple technology, specifically to an assembled temperature measuring thermocouple. Background Technology

[0002] The basic function of a thermocouple is to measure temperature. It works based on the thermoelectric effect, which is a closed circuit composed of two different metals or alloys. When the temperatures of the two junctions are different, a thermoelectric electromotive force is generated in the circuit. The temperature value can be determined by measuring the magnitude of this electromotive force.

[0003] Because the detection tube of existing thermocouples is fixedly connected to the protection tube, the protection tube cannot be disassembled, thus preventing the detection tube from being tested, resulting in poor applicability.

[0004] To address the aforementioned deficiencies, the assembled thermocouple with publication number CN219038207U uses a threaded connection between the upper and lower protective tubes, which facilitates disassembly and assembly as needed, allowing for easy inspection and maintenance of the internal temperature sensing element.

[0005] In actual use of the above-mentioned device, although the protective tube can be disassembled by means of threaded connection, the threaded connection is used for fixing and the adjustment efficiency of the threaded connection is poor, which results in a long time required for disassembly and assembly, thus making the efficiency poor.

[0006] Therefore, we proposed an assembled temperature measuring thermocouple that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide an assembled temperature measuring thermocouple to solve the problem mentioned in the background art that the current market uses threaded connection for fixing, but the threaded connection has poor adjustment efficiency, which leads to a long time required for disassembly and assembly, thus resulting in poor efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an assembled temperature measuring thermocouple, comprising a thermocouple body, wherein a detection tube is provided at the bottom of the thermocouple body;

[0009] The bottom of the thermocouple body is slidably connected to a protective tube, and the bottom of the detection tube extends into the interior of the protective tube, and a positioning bolt is slidably connected to the protective tube.

[0010] The top of the protective tube is fixed with a slider, and the outer end of the slider extends into the interior of the slide groove to form a locking mechanism. The slide groove is opened at the bottom of the thermocouple body. A protrusion is slidably connected inside the slider, and the outer end of the protrusion extends into the interior of the groove to form a locking mechanism. The groove is opened inside the thermocouple body. The inner end of the protrusion is connected to a second spring, and the inner end of the second spring is connected to the interior of the slider to form a limiting mechanism.

[0011] Preferably, the groove is L-shaped and the bottom of the groove is open.

[0012] Preferably, the outer end of the protrusion is semi-circular, and the arc-shaped portion of the outer end of the protrusion fits into the inner wall of the groove.

[0013] Preferably, the protective tube has a buffer layer inside, and the inner wall of the buffer layer is fitted to the outer wall of the detection tube, and the buffer layer is made of rubber material.

[0014] Preferably, the positioning bolt has a sliding connection with a locking block inside, and the inner end of the locking block extends into the interior of the through hole to form a locking mechanism, and the through holes are equally spaced on the protective tube.

[0015] Preferably, the inner end of the locking block is connected to a first spring, and the inner end of the first spring is connected inside the positioning bolt.

[0016] Preferably, the inner end of the locking block is connected to a pull ring, and the pull ring extends out of the interior of the positioning bolt to form a sliding mechanism, and there is a gap between the inner end of the pull ring and the first spring.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the assembled temperature measuring thermocouple is easy to disassemble and adjust; the use of the slider allows for convenient replacement of the protective tube, thus facilitating subsequent maintenance; and the movement of the locking block allows the height of the protective tube to be adjusted according to needs, thereby improving its adaptability. The specific details are as follows:

[0018] A slider is provided, which slides inside the groove, allowing the protective tube to be removed from the thermocouple body, thus achieving convenient assembly and facilitating subsequent disassembly and maintenance of the detection tube.

[0019] It is equipped with a locking block, which disengages from the through hole, allowing the thermocouple body to be adjusted in height via the protective tube. This height adjustment is then made according to different liquid levels, thereby improving its adaptability.

[0020] A buffer layer is provided inside the protective tube, and the inner wall of the buffer layer is fitted to the outer wall of the detection tube. The buffer layer is made of rubber material, which allows it to absorb impact and thus protect the detection tube.

[0021] A first spring is provided, which is connected to the inner end of the locking block and the inner end of the first spring is connected to the inside of the positioning bolt, thereby enabling the first spring to limit the locking block and thus improve the stability of the locking block.

[0030] 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.

[0031] Example 1: An assembled temperature measuring thermocouple solves the problem of poor efficiency caused by the existing threaded connection method, which results in long assembly and disassembly times. By connecting the slider 9 and the groove 10, subsequent maintenance and inspection of the detection tube 2 are facilitated. The following is disclosed:

[0032] The bottom of the thermocouple body 1 is provided with a detection tube 2; a protective tube 3 is slidably connected to the bottom of the thermocouple body 1, and the bottom of the detection tube 2 extends into the interior of the protective tube 3, and a positioning bolt 4 is slidably connected to the protective tube 3; a slider 9 is fixed to the top of the protective tube 3, and the outer end of the slider 9 extends into the interior of the slide groove 10 to form a locking mechanism, and the slide groove 10 is opened at the bottom end inside the thermocouple body 1; a protrusion 11 is slidably connected inside the slider 9, and the outer end of the protrusion 11 extends into the interior of the groove 12 to form a locking mechanism, and the groove 12 is opened inside the thermocouple body 1; a second spring 13 is connected to the inner end of the protrusion 11, and the inner end of the second spring 13 is connected to the interior of the slider 9 to form a limiting mechanism; the slide groove 10 is L-shaped, and the bottom of the slide groove 10 is open; the outer end of the protrusion 11 is semi-circular, and the arc-shaped part of the outer end of the protrusion 11 fits against the inner wall of the groove 12.

[0033] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 When the protective tube 3 needs to be disassembled for inspection and maintenance of the detection tube 2, rotating the protective tube 3 causes the slider 9 to slide inside the groove 10. As the slider 9 slides, it causes the protrusion 11 to press against the groove 12, thus pushing the slider 9 further inward. This sliding also compresses the second spring 13, causing the protrusion 11 to disengage from the groove 12. After the protective tube 3 reaches its position, pulling it causes the slider 9 to disengage from the groove 10. This allows the protective tube 3 to detach from the thermocouple body 1, thus separating the protective tube 3 from the detection tube 2. This facilitates the inspection and maintenance of the detection tube 2. When assembling the protective tube 3, the detection tube 2 is inserted into the interior of the protective tube 3, and then the protective tube 3 is inserted into the interior of the thermocouple body 1. The protective tube 3 is then rotated, which causes the slider 9 to engage inside the slide groove 10. After the protective tube 3 is rotated to the desired position, the force of the second spring 13 will push the protrusion 11 into the groove 12 to engage, thus facilitating the connection between the thermocouple body 1 and the protective tube 3.

[0034] Example 2: A prefabricated temperature measuring thermocouple solves the problem of damage to the detection tube 2 caused by water flow impact in existing systems. The use of a buffer layer 301 protects the detection tube 2, thereby improving its service life. The following is disclosed:

[0035] The protective tube 3 has a buffer layer 301 inside, and the inner wall of the buffer layer 301 is fitted to the outer wall of the detection tube 2. The buffer layer 301 is made of rubber material.

[0036] refer to Figures 1 to 3 When the thermocouple body 1 is detecting the temperature, the detection tube 2 will be inserted into the liquid for detection, and the water flow will impact the protective tube 3. The impact can be absorbed by the buffer layer 301 inside the protective tube 3, and the water flow will come into contact with the detection tube 2 through the through hole 6, thereby avoiding inaccurate temperature detection by the detection tube 2. The buffer layer 301 can protect the detection tube 2, thereby preventing the detection tube 2 from being damaged by impact, and thus improving the service life of the detection tube 2.

[0037] Example 3: A modular thermocouple for temperature measurement solves the problem that existing thermocouples cannot be adjusted according to water level, resulting in poor adaptability. By moving the locking block 5, the position of the detection tube 2 can be easily adjusted, thereby improving the adaptability of the detection. The following is disclosed:

[0038] The positioning bolt 4 has a sliding connection of a locking block 5 inside, and the inner end of the locking block 5 extends into the interior of the through hole 6 to form a locking mechanism. The through holes 6 are evenly spaced on the protective tube 3. The inner end of the locking block 5 is connected to a first spring 7, and the inner end of the first spring 7 is connected to the interior of the positioning bolt 4. The inner end of the locking block 5 is connected to a pull ring 8, and the pull ring 8 extends out of the interior of the positioning bolt 4 to form a sliding mechanism. There is a gap between the inner end of the pull ring 8 and the first spring 7.

[0039] refer to Figures 1 to 4 When the position of the detection tube 2 needs to be adjusted, the positioning bolt 4 is connected to the device via threads, thereby fixing the thermocouple body 1. By pulling the pull ring 8, the pull ring 8 moves, causing the locking block 5 to move. The movement of the locking block 5 compresses the first spring 7, causing it to disengage from the through hole 6. Then, pulling the thermocouple body 1 allows the protective tube 3 to slide within the positioning bolt 4, thus adjusting the position of the detection tube 2. This allows for the detection of water levels at different heights. After adjustment to the appropriate position, the force of the first spring 7 pushes the locking block 5 into the through hole 6, forming a locking mechanism between the locking block 5 and the through hole 6. This fixes the position of the protective tube 3 with the positioning bolt 4, achieving the purpose of height adjustment and improving the adaptability of use.

[0040] Working principle: When using this type of assembled temperature measuring thermocouple, firstly, refer to... Figure 1 , Figure 2 , Figure 5 and Figure 6 When the protective tube 3 needs to be disassembled to inspect and maintain the detection tube 2, the protective tube 3 is rotated, causing the slider 9 to slide inside the slide groove 10. The slider 9 is then pressed into the interior of the slider 9, causing the protrusion 11 to disengage from the interior of the groove 12. After the protective tube 3 is rotated to the position, the protective tube 3 is pulled, causing the slider 9 to disengage from the interior of the slide groove 10. This disengages the protective tube 3 from the thermocouple body 1, thus facilitating the inspection and maintenance of the detection tube 2. When assembling the protective tube 3, the detection tube 2 is inserted into the protective tube 3, and then the protective tube 3 is inserted into the thermocouple body 1. The protective tube 3 is then rotated. After the protective tube 3 is rotated to the position, the force of the second spring 13 pushes the protrusion 11 into the interior of the groove 12 to form a locking mechanism, thus facilitating the connection between the thermocouple body 1 and the protective tube 3.

[0041] refer to Figures 1 to 3 When the thermocouple body 1 is detecting the temperature, the detection tube 2 will be inserted into the liquid for detection, and the water flow will impact the protection tube 3. The impact can be absorbed by the buffer layer 301 inside the protection tube 3. The buffer layer 301 can protect the detection tube 2, thereby avoiding damage to the detection tube 2 from the impact, and thus improving the service life of the detection tube 2.

[0042] refer to Figures 1 to 4 When the position of the detection tube 2 needs to be adjusted, the positioning bolt 4 is connected to the device through the thread, which then fixes the thermocouple body 1. By pulling the pull ring 8, the locking block 5 moves and disengages from the through hole 6. Then, the thermocouple body 1 is pulled, which allows the protective tube 3 to slide within the positioning bolt 4. Therefore, water levels at different heights can be detected. After adjusting to the appropriate position, the force of the first spring 7 pushes the locking block 5 into the through hole 6, which then forms a locking mechanism between the locking block 5 and the through hole 6. This allows the positioning bolt 4 to fix the position of the protective tube 3, thereby achieving the purpose of height adjustment and improving the adaptability of use.
