[0002] In industrial sectors such as petrochemicals, metallurgy, chemical reactors, and marine engineering, temperature is a critical process parameter that directly affects product quality, production efficiency, and equipment safety. Armored thermocouples, due to their advantages of fast response, compact structure, and strong shock resistance, have become the core component for temperature measurement under harsh operating conditions. The installation process of thermocouple corrosion protection sleeves is cumbersome and complicated, and disassembly often requires the assistance of special equipment. This not only consumes a lot of time and significantly extends the maintenance cycle of thermocouples, but also brings many inconveniences to actual maintenance. Therefore, an easy-to-replace armored thermocouple corrosion protection sleeve is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an easily replaceable armored thermocouple corrosion-resistant protective sleeve. By setting up a protective component and a driving component, specifically, pressing one end of the clamping plate lifts the ratchet ring to release the obstruction, thereby driving the inner concave ring to rotate, compressing the spiral spring to store energy. Simultaneously, the convex surface of the inner concave ring moves away from the top plate, causing the tension spring to release its potential energy, driving the limiting block to move. At the same time, the rotating shaft drives the protective plate to unfold outward along the limiting groove. This solves the problem of the cumbersome and complex installation process of existing thermocouple corrosion-resistant protective sleeves, which often requires specialized equipment for disassembly.

[0021] Several fixing components include rectangular posts 2210 that are slidably connected inside the edge of the protective cover 211.

[0023] A tension spring 226 is fixedly connected to the back of the inner wall of the movable groove 227. The end of the tension spring 226 away from the movable groove 227 is fixedly connected to the back of the clamping plate 225. The tension spring 226 is used to keep the clamping plate 225 in contact with the ratchet ring 222.

[0024] A specific application of this embodiment is as follows: When the operator uses the device, they press the locking plate 225 and simultaneously rotate the protective pad 2214. At this time, the locking plate 225 will compress the tension spring 226, causing the tension spring 226 to contract and store elastic potential energy. One end of the locking plate 225 located inside the protective cover 221 is lifted, and the ratchet ring 222 loses its obstruction. Through the operator's rotation, the concave ring 228 is driven, and the concave ring 228 then drives the ratchet ring 222 to rotate. While the ratchet ring 222 is rotating, the internal spiral spring 223 will be subjected to rotational force and contract, storing elastic potential energy. At this time, the convex surface of the concave ring 228 will move away from the top plate 229, so that the top plate 229 loses the squeezing force. The tension spring 2211 releases elastic potential energy, causing the top plate 229 to slide along the preset trajectory of the rectangular column 2210. At the same time, it drives the limiting block 2212. Under the rotation of the concave ring 228, it will drive the rotating shaft 2213 at its bottom to slide along the preset trajectory of the slide groove 214. When the rotating shaft 2213 slides, it will drive the protective plate 215 to unfold outward along the limiting groove 217. When the protective plate 215 slides, it will slide in a straight line along the groove 216 under the restriction of the locking block 213. After rotation, the protective cylinder 231 is engaged along the preset threaded grooves 233 and 232 for initial fixation. Then, the rotational force on the protective pad 2214 is released, allowing the ratchet ring 222 to reset under the elastic potential energy of the coil spring 223, and driving the base plate 218 to rotate. Under the transmission of the base plate 218, the protective pad 2214 is synchronously driven to reset. At the same time, the inner concave ring 228 will press the top plate 229, causing the top plate 229 to synchronously squeeze the tension spring 2211, and pushing out the limit block 2212 to release the protective cylinder 2214. 31 is lifted up, and at the same time, the rotating shaft 2213 will drive the protective plate 215 to move closer. When the protective plate 215 is closed, it will block the bottom insertion port of the protective cover 211. At the same time, the pressure on the clamping plate 225 will be released, and the tension spring 226 will release elastic potential energy to lift the clamping plate 225, so that the clamping plate 225 contacts and locks with the ratchet ring 222. Its armored protective cover 111 is made of tantalum. Tantalum has extremely strong corrosion resistance and has good corrosion resistance to almost all inorganic acids and organic acids. It is especially suitable for extreme corrosive environments such as strong acids and strong alkalis.
