Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, and in particular relates to a thermocouple sensor with a wire-rearing structure. Background Technology

[0002] Thermocouple sensors, as a commonly used temperature measurement device, are widely used in many fields such as industrial production, scientific research and daily life. Their working principle is based on the Seebeck effect, which obtains temperature data by measuring the potential generated by the temperature difference between the two ends of different conductors or semiconductors. The core components of a thermocouple sensor include a sensor probe, sensor electrodes and sensor wires for transmitting electrical signals.

[0003] In practical applications, thermocouple sensors often need to be frequently installed, disassembled, moved, or stored. When the sensor is not in use, the sensor wire usually needs to be wound up and stored. Traditional manual winding methods are prone to damage to the insulation layer of the sensor wire due to uneven force or different winding habits of the operator, which can lead to safety hazards such as short circuits and leakage, seriously affecting the normal thermoelectric potential output of the sensor. Under repeated bending and irregular winding, the internal metal wire of the sensor wire is prone to fatigue or even breakage, thus shortening the service life of the sensor. When the sensor is installed at the detection position for measurement, the sensor wire usually needs to be fixed in order to ensure the cleanliness of the site and avoid cable tangling.

[0004] The cable clips or other simple fixing methods commonly used in the current technology often have the disadvantage of being inconvenient to install and remove. Each adjustment or maintenance requires a lot of time and effort, which increases the maintenance cost.

[0005] Therefore, this invention proposes a thermocouple sensor with a wire-organizing structure to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the prior art, when using and storing thermocouple sensors, the insulation layer of the sensor wire is easily damaged or the metal wire fatigued due to manual winding, and the cable fixing structure is inconvenient to disassemble and install and has high maintenance costs, the present invention aims to provide a thermocouple sensor with a wire management structure that has been improved and can effectively solve the above problems.

[0007] This utility model provides a thermocouple sensor with a wire management structure, including a sensor wire, the sensor wire connecting the two poles of the sensor, the two poles of the sensor connecting the sensor probe; a wire take-up mechanism; and a wire management mechanism.

[0008] The winding mechanism includes a base plate, on which a fixed rotating shaft, a valve, a fixed outer ring, and a sliding outer ring are provided. The valve is connected to the fixed rotating shaft. One end of the fixed rotating shaft is connected to the moving rotating shaft by a snap fastener to form a whole. The other end of the fixed rotating shaft can be rotatably inserted into the fixed outer ring. The sliding outer ring is detachably slidably fixed inside the base plate and can rotatably support one end of the moving rotating shaft.

[0009] Furthermore, the cable management mechanism is located on the outer wall of the sensor cable. It includes a fixed base, a guide post and a limiting ring on the fixed base, a top cover slidably connected to the guide post, the sliding stroke of the top cover is limited by the limiting ring, a locking shaft and a lock head are provided inside the top cover, the rotation of the locking shaft drives the lock head to slide inside the top cover to fix the top cover, and the cable management mechanism is fixed to the object by bolts.

[0010] Preferably, the fixed rotating shaft has a groove at one end, and the end of the sensor wire closest to the two poles of the sensor is installed in the groove.

[0011] Preferably, the sliding outer ring is located at the end of the fixed rotating shaft near the moving rotating shaft.

[0012] Preferably, when the valve rotates, it drives the fixed shaft to rotate inside the fixed outer ring and the sliding outer ring, thereby achieving the purpose of winding up the sensor wire.

[0013] Preferably, after the winding mechanism has finished winding the sensor wire, the sliding outer ring and the moving shaft are detachable so that the wound sensor wire can be removed.

[0014] Preferably, the wire management mechanism is fixed at equal and uniform intervals on the outer wall of the sensor wire.

[0015] Preferably, after the top cover slides to the position of the limiting ring inside the guide post, it can be rotated to lock the sensor line into the fixed base.

[0016] Preferably, after the top cover is returned to its original position, rotating the locking shaft causes the locking head to slide inside the top cover to fix the top cover, thereby fixing the sensor wire.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems in the prior art where uneven winding force during manual winding leads to damage to the wire insulation layer, causing short circuits or leakage, preventing the sensor from outputting thermoelectric potential normally, and causing fatigue of the metal wire due to repeated bending. It achieves the technical effect of effectively protecting the sensor wire and extending its service life.

[0019] 2. This utility model solves the problem of the difficulty in taking out or replacing wound cables in the prior art by designing a detachable sliding outer ring and a moving rotating shaft in the cable winding mechanism, thereby achieving the technical effect of facilitating the use, storage and maintenance of cables and improving the ease of operation.

[0020] 3. This utility model solves the problem of difficulty in removing the original cable management buckle after fixing and the increase in maintenance costs by setting a cable management mechanism with a locking shaft and a lock head cooperating with the top cover. It achieves the technical effect of conveniently and quickly fixing and unfixing the sensor cable, effectively reducing the later maintenance cost.

[0021] 4. This utility model solves the problem of messy and tangled sensor wires in the prior art by fixing them evenly and at equal intervals on the outer wall of the sensor wires through a wire management mechanism.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a thermocouple sensor with a wire management structure, which aims to solve the problems in the prior art where thermocouple sensor wires are easily damaged during storage and use, are difficult to organize and fix, and have high maintenance costs.

[0031] like Figure 1 and Figure 2 As shown, the thermocouple sensor with a wire management structure includes a sensor wire 1, a wire take-up mechanism 2, and a wire management mechanism 3. The sensor wire 1 connects to the two sensor poles 4, and the two sensor poles 4 are further connected to the sensor probe 5. The wire take-up mechanism 2 is used to wind up the sensor wire 1, and the wire management mechanism 3 is set on the outer wall of the sensor wire 1. The sensor wire 1 serves as the main body for signal transmission, connecting the sensor probe 5 and the two sensor poles 4 to form the basic temperature sensing and signal output unit of the thermocouple sensor. The wire take-up mechanism 2 serves as a platform for storing and unfolding the sensor wire 1, and the wire management mechanism 3 serves as a local fixing device for the sensor wire 1 during use.

[0032] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the thermocouple sensor with the wire management structure also includes a wire take-up mechanism 2, and a specific winding and unwinding cooperation relationship is formed between the wire take-up mechanism 2 and the sensor wire 1.

[0033] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 4 The core structure of the take-up mechanism 2 will be described in detail below:

[0034] The take-up mechanism 2 includes a base plate 204, on which a fixed rotating shaft 201, a valve 202, a fixed outer ring 203, and a sliding outer ring 205 are mounted. The valve 202 is connected to the fixed rotating shaft 201, meaning that when the valve 202 rotates, it drives the fixed rotating shaft 201 to rotate, thus enabling the winding or unwinding of the sensor wire 1. One end of the fixed rotating shaft 201 is connected to the moving rotating shaft 206 via a snap-fit ​​mechanism, forming a rotatable roll structure for winding the sensor wire 1. The other end of the fixed rotating shaft 201 is rotatably engaged inside the fixed outer ring 203, which provides stable support for the rotation of the fixed rotating shaft 201. The sliding outer ring 205 is detachably and slidably fixed inside the base plate 204 and rotatably supports the other end of the moving rotating shaft 206. This support structure ensures the stability and smoothness of the roll when winding the sensor wire 1.

[0035] The fixed rotating shaft 201 has a groove at one end, and the end of the sensor wire 1 near the two poles 4 of the sensor is installed in the groove to facilitate the initial fixation of the sensor wire 1 to the reel. The sliding outer ring 205 is set at the end of the fixed rotating shaft 201 near the moving rotating shaft 206. When the valve 202 rotates, it drives the fixed rotating shaft 201 to rotate inside the fixed outer ring 203 and the sliding outer ring 205, thereby achieving the purpose of winding the sensor wire 1. After the sensor wire 1 is wound up, the sliding outer ring 205 and the moving rotating shaft 206 can be detached from the base plate 204 and the fixed rotating shaft 201 to facilitate the removal of the wound sensor wire 1. This detachable design greatly improves the convenience of storage and maintenance.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0037] The cable management mechanism 3 is installed on the outer wall of the sensor cable 1. It includes a fixed base 301, a guide post 302, a limiting ring 303, a top cover 304, a locking shaft 305, a lock head 306, and bolts 307. The fixed base 301 is provided with the guide post 302 and the limiting ring 303. The top cover 304 is slidably connected to the guide post 302. The sliding stroke of the top cover 304 is limited by the limiting ring 303 to ensure that the top cover 304 can slide smoothly and accurately into place when opening and closing. The top cover 304 is provided with the locking shaft 305 and the lock head 306. The rotation of the locking shaft 305 drives the lock head 306 to slide inside the top cover 304 to fix the top cover 304. The entire cable management mechanism 3 is fixed to the object by bolts 307, thereby realizing the arrangement and fixation of the sensor cable 1.

[0038] In a preferred embodiment, the cable management mechanism 3 is fixed at equal and uniform intervals on the outer wall of the sensor cable 1, which ensures that the sensor cable 1 is well supported and kept neat along its entire length.

[0039] As another preferred embodiment, after the top cover 304 slides within the guide post 302 to the position of the limiting ring 303, it can be rotated to lock the sensor line 1 into the fixed base 301, making installation and removal more convenient and reducing operation steps.

[0040] In another preferred embodiment, after the top cover 304 is in place, rotating the locking shaft 305 causes the locking head 306 to slide inside the top cover 304 to fix the top cover 304, thereby achieving a firm fixation of the sensor line 1, effectively preventing the cable from accidentally falling off or shifting, and ensuring the stability of the sensor operation.

[0041] Working principle: When the sensor probe 5 is no longer in use, first remove the sensor electrodes 4. Then, install the end of the sensor wire 1 near the sensor electrodes 4 onto the end of the fixed rotating shaft 201 with a groove. After installing the sensor electrodes 4, fix the moving rotating shaft 206 to the fixed rotating shaft 201 with a snap-fit ​​mechanism, forming a single reel. Then, the protruding part of the other end of the fixed rotating shaft 201 is rotatably inserted into the fixed outer ring 203. As the fixed rotating shaft 201 is inserted into the fixed outer ring 203, install the sliding outer ring 205 onto the end of the fixed rotating shaft 201 near the moving rotating shaft 206. The bottom of the 05 is detachably slidably fixed inside the base plate 204. After the overall installation is completed, the valve 202 is turned. The valve 202 drives the two ends of the fixed rotating shaft 201 to rotate inside the fixed outer ring 203 and the sliding outer ring 205 respectively, thereby achieving the purpose of winding up the sensor wire 1. After winding up the sensor wire 1, the sliding outer ring 205 slidably fixed inside the base plate 204 and the moving rotating shaft 206 snapped inside the fixed rotating shaft 201 are removed, thereby taking out the wound sensor wire 1. The setting of the winding mechanism 2 effectively solves the problems of uneven winding force causing damage to the wire insulation layer, short circuit or leakage, and fatigue of metal wire caused by repeated bending.

[0042] After the sensor probe 5 of sensor wire 1 is installed in the detection position, the wire management mechanism 3, which is evenly fixed at equal intervals on the outer wall of sensor wire 1, comes into play. Rotating the locking shaft 305 of the wire management mechanism 3 causes the fixed locking head 306 to rotate inside the top cover 304 to the slotted position. Pulling the top cover 304 causes the other end of the top cover 304 to slide inside the guide post 302 to the position of the limiting ring 303. Rotating the top cover 304 then secures the sensor wire 1 inside the fixed base 301. After the sensor wire 1 is installed in the fixed base 301, the top cover 304 is rotated back. After the top cover 304 is in place, the locking shaft 305 is rotated. The locking shaft 305 drives the lock head 306 to slide inside the top cover 304, fixing the top cover 304 and thus fixing the sensor wire 1. Subsequently, the entire wire management mechanism 3 is fixed to the object by bolts 307, thereby realizing the organization and fixing of the sensor wire 1. The wire management mechanism 3 solves the problems of difficulty in removing the original wire management clips after fixing and increased maintenance costs.
