One side wall of the two rectangular sliders 331 that are away from each other is fixedly provided with an L-shaped rod 332 that penetrates the protective tube 2 and is attached to the lower end surface of the cylindrical table 31. A clamping piece 333 is also provided inside the protective tube 2 and at one end that is close to the two rectangular sliders 331.

[0046] A return groove 3311 which is turned 90 degrees and has an arc-shaped top is formed on the end face of the rectangular slider 331 away from the sliding groove 23. An adjustment rod 3312 with one end always located inside the return groove 3311 is slidingly arranged inside the return groove 3311. The other end of the adjustment rod 3312 is fixedly connected to the inner wall of the protective tube 2 through a torsion spring.

[0047] The engaging member 333 includes a connecting tube 3331 which is fixedly arranged inside the protective tube 2 and has a through hole in the center. The lower end surface of the connecting tube 3331 is fixedly provided with a plurality of engaging pieces 3332 distributed along the circumferential direction by a torsion spring. The outer walls of the plurality of engaging pieces 3332 are sleeved with an annular plate 3333 whose inner wall is provided with a telescopic top piece. The outer wall of the annular plate 3333 is fixedly connected to the rectangular slider 331 via two shafts.

[0048] The inner wall of the flange 41 is provided with a plurality of arc grooves along the circumferential direction, and a pawl 411 is provided inside the plurality of arc grooves through a torsion spring, and the lower end surface of the pawl 411 is fixedly connected to the flange 41 through a spring, and a round rod penetrating the flange 41 is fixedly provided on the upper end surface of the pawl 411, and an annular pressure plate 412 is fixedly provided on the upper ends of the plurality of round rods.

[0049] The locking assembly 42 includes a ratchet plate 421 which is rotatably arranged inside the flange 41 and has four arc grooves on its upper end surface in the circumferential direction. A toggle rod 422 which passes through the flange 41 is fixedly arranged on the upper end surface of the ratchet plate 421. A locking plate 423 is slidably arranged inside the flange 41 and below the ratchet plate 421 at positions corresponding to the four sliding grooves. The two ends of the locking plate 423 respectively pass through the inner and outer side walls of the flange 41, and a linkage rod 424 which is always located inside the arc groove is fixedly arranged on the upper end surface of the locking plate 423. A push rod 425 which is fixedly arranged on the upper end surface of the linkage rod 424 and which cooperates with the telescopic block 323 to press against the top is also fixedly arranged on the upper end surface of the linkage rod 424.

[0050] A telescopic top block 4231 located inside the rectangular groove is fixedly provided on one end face of the locking plate 423 close to the inner wall of the protection tube 2, and an L-shaped top plate 4232 is fixedly provided downward on one side of the locking plate 423 close to the outer wall of the flange 41, and the upper end face of the horizontal section of the L-shaped top plate 4232 is in close contact with the lower end face of the external flange.

[0051] During the specific implementation, the installation work of the flange 41 and the protection tube 2 is as follows:

[0052] Initially, push the flange 41 to slide along the outer wall of the protection tube 2 until the flange 41 moves to the position of the annular groove 22. Then, fit the flange 41 with the external flange. At this time, the circular holes for bolt connection on the two flanges are in different positions. Subsequently, control the toggle lever 422 to drive the ratchet disc 421 to rotate. During the rotation of the ratchet disc 421, since the setting direction is the same as that of the pawl 411, it is not restricted. During the rotation of the ratchet disc 421, the arc-shaped groove formed on it will gradually drive the locking plate 423 and the linkage rod 424 to slide along the inside of the flange 41. During the sliding of the locking plate 423, the telescopic top block 4231 provided at one end of it is pushed and retracted by the outer wall of the protection tube 2, while the L-shaped top plate 4232 provided at the other end of the locking plate 423 will gradually approach and closely adhere to the lower end surface of the external flange.

[0053] Immediately afterwards, control the toggle lever 422 to drive the ratchet disc 421 to reverse. Since the pawl 411 abuts against the position of the ratchet disc 421, the overall rotation of the flange 41 will be driven by the ratchet disc 421. During the rotation of the flange 41, the circular holes of the flange 41 and the external flange are gradually aligned. At the same time, during the rotation of the four locking plates 423 around the protection tube 2, when the telescopic top block 4231 moves into the rectangular groove, the pushing force disappears and it quickly pops out and is stuck in the rectangular groove. Finally, lock and fix the upper and lower flanges by means of bolts and nuts, and the locking installation work of the flange 41, the protection tube 2 and the external flange can be completed.

[0054] It should be noted that during the rotation of the four locking plates 423, their side walls push against the corresponding connection blocks, and the four connection blocks drive their respective arc-shaped plates 222 to slide along the rectangular chute. The four arc-shaped plates 222 together form an annular area, aiming to prevent the metal wire inside the assembled thermal resistor from directly contacting the inner wall of the protection tube 2, thereby ensuring the stability of heat conduction and signals.

[0055] Installation work of the junction box body 1 and the protection tube 2:

[0056] After the locking installation work of the flange 41 and the protection tube 2 is completed, the push rods 425 provided on the upper end surfaces of the four linkage rods 424 approach synchronously with the locking plate 423. Place the annular ring 321 along the strip-shaped groove 21 so that the upper end surfaces of the four push rods 425 pass through the square through slots, and complete the pushing work on the telescopic latch 323 through the push rods 425. Then, slide the cylindrical platform 31 along the folded line groove 3212. The telescopic latch 323 retracts under the push of the outer wall of the cylindrical platform 31. Immediately afterwards, rotate the cylindrical platform 31 along the folded line groove 3212 and press it down. At this time, the locking groove 312 moves to the position of the telescopic latch 323, and the telescopic latch 323 without push quickly pops out and cooperates with the cylindrical platform 31 to be clamped tightly. Thus, the locking work of the cylindrical platform 31 and the protection tube 2 is completed.

[0057] When the cylindrical table 31 is pressed down, its lower end surface will push downward against the two L-shaped rods 332. The two L-shaped rods 332 will drive the rectangular slider 331 to move during the downward movement, and make the adjustment rod 3312 slide along the return groove 3311. The non-torsion spring end of the adjustment rod 3312 moves to the arc-shaped part at the top of the return groove 3311, thereby completing the locking work of the rectangular slider 331. The rectangular slider 331 will simultaneously drive the annular plate 3333 to move during the sliding process. Through the telescopic top plate provided on the annular plate 3333, the multiple engaging pieces 3332 are gradually squeezed into a cone shape with a larger diameter at the top and a smaller diameter at the bottom. The outer wall of the metal wire is engaged by the multiple engaging pieces 3332 in a cone shape, so that the metal wire can be prevented from vibrating due to force during operation, thereby further improving the thermal conductivity and signal stability of the assembled thermal resistor during operation.

[0058] Unlocking work of cylindrical table 31 and protection tube 2:

[0059] As can be seen from the above, the adjusting rod 3312 is located at the top of the return groove 3311, and the cylindrical table 31 is pressed downwardly. The chamfered corner at the upper end of the locking groove 312 contacts and cooperates with the telescopic block 323, so that the telescopic block 323 is retracted. At the same time, the adjusting rod 3312 will be separated from the arc section at the top of the return groove 3311 under the action of the torsion spring, and then the cylindrical table 31 is rotated, so that the sliding block 311 set on the cylindrical table 31 enters the L-shaped groove 3211. The rectangular sliding block 331 without a limit is driven by the spring to The L-shaped rod 332 and the annular plate 3333 move upward rapidly, and during the resetting process, the L-shaped rod 332 pushes the cylindrical table 31 upward, causing the cylindrical table 31 to slide upward along the L-shaped groove 3211 and gradually separate from the protective tube 2. At the same time, the annular plate 3333 separates from the engagement piece 3332 during the upward movement, so that several engagement pieces 3332 rebound and reset and separate from the metal wire. After all separation is completed, the metal wire can be pulled out from the inside of the protective tube 2 by continuing to pull the junction box body 1.

[0060] Unlocking work of flange 41 and protection tube 2:

[0061] Press the annular pressure plate 412 downward, and then several pawls 411 disengage from the ratchet disk 421. The ratchet disk 421 is then rotated by the toggle rod 422. The four locking plates 423 are synchronously moved away from the protective tube 2 under the drive of the arc groove, and the L-shaped top plate 4232 also gradually moves away from the lower end surface of the external flange. Then, the bolts and nuts between the upper and lower flanges 41 are removed to complete the unlocking of the flange 41 and the protective tube 2.

[0062] It is worth emphasizing that the assembled thermal resistor also has the following advantages:

[0063] Advantage 1: The sliding block 311 provided on the frustum 31 is locked by pressing down along the broken line groove 3212 and then rotating. With the interaction between the locking groove 312 and the telescopic clamping block 323, the quick unlocking and installation of the junction box and the protection tube 2 are realized, improving the disassembly and replacement efficiency of the assembled thermal resistance during the detection process.

[0064] Advantage 2: The flange 41 and the protection tube 2 are locked by the synchronous approach of the four locking plates 423 and the telescopic top blocks 4231, which also simplifies the installation steps and improves the installation efficiency. At the same time, during the movement of the locking plate 423, the L-shaped top plate 4232 provided thereon is in close contact with the lower end face of the external flange 41, thereby ensuring the connection strength of the two flanges 41.

[0065] Advantage 3: When the four telescopic top blocks 4231 rotate and snap into the rectangular groove, the corresponding arc plates 222 are pushed by the locking plate 423, so that the four arc plates 222 approach synchronously and enclose an annular area. The annular area is used to block and prevent the metal wire from directly contacting the outer wall of the protection tube 2, thereby improving the stability of the detection result.

[0066] Advantage 4: The cooperation between the rectangular slider 331 and the return groove 3311, and the adjustment of the annular plate 3333 to the holding piece 3332 ensure the stable holding of the metal wire during operation and avoid vibration interference.

[0067] Advantage 5: The junction box body 1 and the frustum 31 are rotationally connected, enabling the junction box body 1 to perform multi-directional position adjustment relative to the frustum 31. This not only greatly improves the operation convenience but also allows for quick and accurate adjustment of the position of the junction box body 1 according to actual needs.

[0068] Advantage 6: After the flange 41 is installed and locked, the push rod 425 provided thereon snaps into the square through groove of the strip 322 on the annular ring 321, realizing the tight fit between the flange 41 and the annular ring 321. Subsequently, after the pressing and rotating action of the frustum 31 is completed, it enters the annular ring 321. At this time, the annular ring 321 is firmly locked and cannot move upward. The telescopic clamping block 323 designed on the annular ring 321 is pushed out by the push rod 425 and cooperates with the locking groove 312 on the frustum 31 to be clamped tightly. Through the linkage locking mechanism among the flange 41, the annular ring 321, the frustum 31, and the protection tube 2, the overall locking strength is significantly improved, effectively avoiding the phenomenon of loose vibration connection of the connecting block caused by long-term work, and thus ensuring the stability of the device.
