[0002] Dual thermocouple sensors are temperature measurement devices that utilize the principle of redundancy design. By deploying two independent thermocouple elements at the same temperature measurement point, the reliability, safety, and availability of the system are significantly improved. When one element fails, the other can provide backup data. At the same time, the comparison of the two readings can also provide valuable diagnostic information, making it easier to detect faults in a timely manner. It is an important technical means to ensure safe operation in temperature monitoring of critical industrial processes and equipment.

[0003] In the prior art, patent application document "CN222812477U" discloses a "group thermocouple"; it includes a junction box, a conductive bus, and two groups of thermocouples; one end of the conductive bus extends into the junction box, each group of thermocouples includes two thermocouple bodies, the two thermocouple bodies in each group are connected in parallel and electrically connected to one of the wire cores in the conductive bus, and the terminals of each thermocouple body are fixed to the side wall of the junction box; this utility model improves the integration of thermocouples and facilitates the use of thermocouples. In addition, it can improve measurement accuracy and reduce measurement errors.

[0004] The above-mentioned "still has some drawbacks. For example, when using two independent thermocouple sensors to detect a single point, a fixed clamp is required to fix the two thermocouple sensors. If a single thermocouple sensor is damaged, the fixed clamp needs to be cut off, and the replacement and repair are cumbersome. At the same time, the fixed clamp cannot adjust the distance between the two thermocouple sensors according to different detection points.

[0005] To address this issue, a dual thermocouple sensor is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a dual thermocouple sensor to solve the problems mentioned in the background art, such as the need to cut off the fixing clamp when a single thermocouple sensor is damaged, making replacement and repair cumbersome, and the inability of the fixed clamp to adjust the distance between the two thermocouple sensors according to different detection points.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dual thermocouple sensor, comprising a sensor body, a junction box fixedly connected to one side of the sensor body, a main protective box provided inside the sensor body, an inner limiting frame provided on one side of the main protective box, an inner snap-fit ​​plate fixedly connected to the inner side of the inner limiting frame, a side snap-fit ​​plate engaged with the surface of the inner snap-fit ​​plate, a spring body fixedly connected to one side of the side snap-fit ​​plate, a connecting frame fixedly connected to one side of the spring body, and a limiting sleeve fixedly connected to one side of the connecting frame.

[0008] Preferably, there are multiple side latching plates, and each of the multiple side latching plates has a gripping plate fixedly connected to one side.

[0009] Preferably, there are two connecting frames, and telescopic rods are fixedly connected to both sides of the two connecting frames, with a side locking plate provided at one end of each telescopic rod.

[0010] Preferably, a side transmission box is provided on one side of the main protective box, an internal threaded hole is provided on one side of the side transmission box, a connecting frame is provided on one side of the main protective box, a threaded rod is threadedly connected to the inner side of the internal threaded hole, a first helical gear is fixedly connected to one side of the threaded rod, a second helical gear is meshed with one side of the first helical gear, a side fixing rod is fixedly connected to one side of the second helical gear, and a gripping ring is fixedly connected to one side of the side fixing rod.

[0011] Preferably, a second bearing disk is movably connected to one side of the second helical gear disk, a limiting plate is movably connected to one side of the second bearing disk, and one side of the limiting plate is fixedly connected to the inner side of the connecting frame.

[0012] Preferably, a side limiting rod is fixedly connected to one side of the first helical gear disk, a first bearing disk is movably connected to one side of the side limiting rod, and one side of the first bearing disk is movably connected to the inner side of the connecting frame.

[0013] Compared with the prior art, this utility model provides a dual thermocouple sensor, which has the following advantages:

[0014] 1) In the operation of this dual thermocouple sensor, after the two side snap-fit ​​plates move horizontally and separate from the inner snap-fit ​​plate in the inner limit frame, the connecting frame can be freely raised and lowered along the inner side of the inner limit frame after the side snap-fit ​​plates and the inner snap-fit ​​plates lose their snap-fit ​​limit. After the height is adjusted, by releasing the grip plate, the spring body will reset after losing its limit and push the side snap-fit ​​plates to move. After the side snap-fit ​​plates reset, they will snap with the inner snap-fit ​​plates to limit and fix the sensor body, which improves the portability of the two sensor bodies after the limit is set.

[0015] 2) In the operation of this dual thermocouple sensor, the rotating threaded rod and the threaded connection of the internal threaded hole are used. When the threaded rod rotates, it will drive the side transmission box to move horizontally. By adjusting the distance between the side transmission box and the main protective box, the distance between the two limit sleeves can be adjusted. The distance between the two sensor bodies can be adjusted in a portable way, which improves the portability and effectiveness of the adjustment after the two sensor bodies are installed.

[0029] It should be noted that by pushing the gripping plate 305, the side locking plate 304 is moved. When the side locking plate 304 is pushed, the spring body 307 will undergo compression deformation, and the telescopic rod 306 will retract, which improves the stability of the spring body 307 during extension and retraction.

[0030] In an optional embodiment: a side transmission box 402 is provided on one side of the main protective box 301, an internal threaded hole 403 is provided on one side of the side transmission box 402, a connecting frame 401 is provided on one side of the main protective box 301, a threaded rod 404 is threadedly connected to the inner side of the internal threaded hole 403, a first helical gear 405 is fixedly connected to one side of the threaded rod 404, a second helical gear 408 is meshed with one side of the first helical gear 405, a side fixing rod 4011 is fixedly connected to one side of the second helical gear 408, and a gripping ring 4012 is fixedly connected to one side of the side fixing rod 4011.

Utilizing the threaded connection between the rotating threaded rod 404 and the internal threaded hole 403, the rotation of the threaded rod 404 will drive the side transmission box 402 to move horizontally.

[0032] In an optional embodiment: a second bearing disk 409 is movably connected to one side of the second helical gear disk 408, a limiting plate 4010 is movably connected to one side of the second bearing disk 409, and one side of the limiting plate 4010 is fixedly connected to the inner side of the connecting frame 401.

[0033] It should be noted that the rotating helical gear disc 408 is movably supported on one side of the limiting plate 4010 via the bearing disc 409, which improves the rotational stability of the side fixing rod 4011.

[0034] In an optional embodiment: a side limiting rod 406 is fixedly connected to one side of the first helical gear disk 405, a first bearing disk 407 is movably connected to one side of the side limiting rod 406, and one side of the first bearing disk 407 is movably connected to the inner side of the connecting frame 401.

[0035] It should be noted that when the side limit rod 406 rotates, it is movably supported on the inner side of the connecting frame 401 by the first bearing plate 407, which improves the stability of the rotation of the side limit rod 406.

[0036] The specific usage and function of this embodiment: After the limiting sleeve 309 is sleeved on the surface of the sensor body 1, when it is necessary to adjust the height of the two sensor bodies 1 along both sides of the main protective box 301, first press the grip plates 305 on both sides of the connecting frame 308. By pushing the grip plates 305, the side locking plates 304 are driven to move. After being pushed, the side locking plates 304 will cause the spring body 307 to undergo compression deformation, and drive the telescopic rod 306 to retract, which improves the stability of the spring body 307 during extension and retraction. By driving the two side locking plates 305... 4. After horizontal movement, it separates from the inner locking plate 303 in the inner limit frame 302. After the side locking plate 304 loses its locking limit with the inner locking plate 303, the connecting frame 308 can freely rise and fall along the inner side of the inner limit frame 302. After the height is adjusted, by releasing the grip plate 305, the spring body 307 will reset after losing its limit and push the side locking plate 304 to move. After the side locking plate 304 resets, it will lock with the inner locking plate 303 to limit and fix the sensor body 1, which improves the portability of the two sensor bodies 1 after the limit is set.

[0037] When adjusting the distance between the two limiting sleeves 309 and both sides of the main protective box 301, first, grasp the grip ring 4012 and rotate it. The rotating grip ring 4012 will drive the side fixing rod 4011 to rotate along the inner side of the connecting frame 401. The rotating side fixing rod 4011 will drive the second helical gear disc 408 to rotate. The rotating second helical gear disc 408 will drive the meshing first helical gear disc 405 to rotate. The rotating first helical gear disc 405 will drive the side limiting rod 406 to move forward. The rotating helical gear disk 405 drives the threaded rod 404 to rotate synchronously. The threaded rod 404 and the internal threaded hole 403 are connected by a thread. When the threaded rod 404 rotates, it drives the side transmission box 402 to move horizontally. By adjusting the distance between the side transmission box 402 and the main protective box 301, the distance between the two limit sleeves 309 can be adjusted. The distance between the two sensor bodies 1 can be adjusted in a portable way, which improves the portability and effectiveness of the adjustment after the two sensor bodies 1 are installed.
