[0031] like Figure 3-4 As shown, in the present embodiment, the temperature measuring unit 200 includes a fixed block 210, the fixed block 210 and the plug-in slot 111 are slidably plugged, a magnet 211 is provided on the side wall of the fixed block 210 near the plug-in slot 111, a clamping groove 212 is provided on the side wall position of the fixed block 210 corresponding to the line-following tube 126, a gooseneck tube 213 is fixedly connected to the outer wall of the fixed block 210 corresponding to the line-following tube 126, the other end of the gooseneck tube 213 is fixedly connected to the temperature measuring tube 214, the other end of the temperature measuring tube 214 is provided with a thread, the outer wall of the temperature measuring tube 214 with a thread is screwed and connected to a measuring head 220, a telescopic airbag 230 is installed in the middle section of the measuring head 220, the outer wall of the measuring head 220 is provided with a thread, and the outer wall of the measuring head 220 is sleeved and screwed with an adjusting The section module 240, the adjustment module 240 includes a ring 1 241 and a ring 242, the inner wall of the ring 1 241 is provided with a thread, the ring 1 241 and the outer wall of the measuring head 220 provided with a thread are screwed together, two connecting frames 243 are symmetrically fixed between the ring 1 241 and the ring 242, the outer walls of the two connecting frames 243 are slidably connected with sliding rods 245, the opposite ends of the two sliding rods 245 are fixedly connected with rubber pads 246, the outer walls of the two sliding rods 245 located between the connecting frames 243 and the rubber pads 246 are movably sleeved with reset springs 247, the two side walls of the two connecting frames 243 are fixedly connected with lifting frames 244, and the tops of each two lifting frames 244 are in contact with the inner arc surface of the corresponding rubber pads 246.

[0032] In this embodiment, when long-distance measurement is required, the fixed block 210 is slid upward from the plug-in slot 111 to separate the temperature measuring unit 200 from the sensor body 100. The side wall of the fixed block 210 is provided with a magnet 211, so that the fixed block 210 can be adsorbed on a metal object at will, which is convenient for fixing and disassembly. The gooseneck tube 213 is fixedly connected to the outer wall of the fixed block 210, so that when encountering an angle that is difficult to measure, the gooseneck tube 213 can be bent to adjust the measuring angle of the measuring head 220; the measuring head 220 and the temperature measuring tube 214 are screwed together, so that the two are easy to disassemble and replace. When measuring some relatively small positions that the fixed block 210 and the temperature measuring tube 214 cannot enter, the fixed block 210 can be fixed nearby, and the measuring head 220 can be removed from the temperature measuring tube 2 The end of 14 is unscrewed, the measuring head 220 is sent to the measuring point, and the telescopic airbag 230 is inflated to expand outward. The outer surface of the expanded telescopic airbag 230 will push the two slide bars 245, so that the two slide bars 245 move outward with the rubber pads 246 respectively, so that the outer arc surface of the rubber pads 246 contacts the inner wall of the measuring point in the narrow area, so that the position of the measuring head 220 at the measuring point is fixed, and the measuring head 220 is prevented from shifting during measurement, which affects the measurement accuracy; according to different measurement environments, users can replace the measuring head 220 and the adjustment module 240 of different materials and sizes to meet the needs of different measurement environments and measurement objects, such as high temperature environments require high temperature resistant materials, and corrosive environments require corrosion-resistant materials, thereby improving the applicability and flexibility of the sensor.

[0033] like Figure 8 As shown, in this embodiment, the air supply unit 300 includes an extrusion airbag 310, the top surface of the extrusion airbag 310 is fixedly connected to the bottom surface of the shell 110, the top surface of the extrusion airbag 310 is fixedly connected to an annular seat 320, the outer wall of the annular seat 320 is fixedly connected to the inner wall of the shell 110, the top surface of the annular seat 320 is rotatably connected to a conductive ring 330, the bottom surface of the extrusion airbag 310 is fixedly connected to four supporting feet 311 at equal angles, the inner bottom surface of the extrusion airbag 310 is installed with a one-way air intake valve 1 312, the inner top surface of the extrusion airbag 310 is installed with a one-way air intake valve 2 313, and the one-way The top of the second intake valve 313 is connected to the air supply pipe 1 318 and the exhaust pipe 314 through the three-way pipe 316. The exhaust pipe 314 passes through the annular seat 320 and extends to the outside of the shell 110. The end of the exhaust pipe 314 is installed with a fastening gas nozzle 315. The top of the air supply pipe 1 318 is fixedly connected to the series pipe 317. The top surface of the series pipe 317 is rotatably connected to the air supply pipe 2 319.

The other end of the air supply pipe 2 319 is connected to the telescopic airbag 230.

[0034] In a specific implementation, a wire and a second air delivery pipe 319 are wrapped in the rubber sleeve 331. One end of the second air delivery pipe 319 in the rubber sleeve 331 is connected to the series pipe 317 by rotation, and the other end is connected to the telescopic airbag 230. A second one-way air intake valve 313 and a first one-way air intake valve 312 are respectively installed on the inner top surface and the inner bottom surface of the extrusion airbag 310, so that when the extrusion airbag 310 is pressed, the air inside the extrusion airbag 310 will not escape from the first one-way air intake valve 312, but will pass through the second one-way air intake valve 313 and sequentially pass through the three-way pipe 316, the first air delivery pipe 318, the series pipe 317, and the second air delivery pipe 319, and then enter the telescopic airbag 230, so that the telescopic airbag 230 bulges and moves the two slide bars 245 to the The two rubber pads 246 are pushed outward to expand outward to increase the volume of the measuring head 220, so that the temperature measuring unit 200 is fixed in the measuring area. In addition, since a one-way air inlet valve 2313 is installed, the gas entering the telescopic airbag 230 will not return to the extrusion airbag 310, thereby avoiding difficulty in inflation. When the measurement is completed and the measuring head 220 needs to be retracted, the gas in the telescopic airbag 230 will flow along the air supply pipe 2319, pass through the three-way pipe 316 and be released from the exhaust pipe 314 by loosening the fastening air nozzle 315. The sliding rod 245 that has lost its thrust will drive the two rubber pads 246 to move closer to each other and return to their original state under the rebound action of the reset spring 247, and will no longer be in close contact with the measuring point. At this time, the measuring head 220 can be recovered. Example

[0035] like Figure 5-7 As shown, in this embodiment, the winding module 120 includes a servo motor 121, the outer wall of the servo motor 121 is fixedly connected to the inner wall of the housing 110, the motor shaft of the servo motor 121 is drivingly connected to a winding roller 122, the top end of the winding roller 122 is rotatably connected to the inner top surface of the housing 110, the winding roller 122 is drivingly connected to a screw rod 123 through a pulley 124, the top end of the screw rod 123 is rotatably connected to the inner top surface of the housing 110, and the winding roller 122 is drivingly connected to a screw rod 123 through a pulley 124. A cylindrical shell 127 is provided on the outside of 22, the top surface of the cylindrical shell 127 is fixedly connected to the inner top surface of the outer shell 110, the outer wall of the cylindrical shell 127 is slidably connected to a wiring ring 125, the wiring ring 125 and the outer wall of the screw rod 123 are screwed together, the outer wall of the wiring ring 125 close to the temperature measuring unit 200 is fixedly connected to a wiring tube 126, and a wiring groove 1271 is opened at a position of the outer wall of the cylindrical shell 127 corresponding to the travel route of the wiring tube 126.

[0036] During specific implementation, the rubber sleeve 331 is wound around the outer wall of the winding roller 122 and passes through the wiring groove 1271, the wire-guiding tube 126, the fixed block 210 and the gooseneck tube 213 in sequence to extend into the temperature measuring tube 214 and be connected to the measuring head 220. When the motor shaft driving the servo motor 121 is transmitted to the servo motor 121, the screw rod 123 will rotate with the winding roller 122 under the transmission of the pulley 124, so that the wire-guiding ring 125 guides the rubber sleeve 331 to move back and forth along the screw rod 123, so that the stretched rubber sleeve 331 is more evenly wound around the winding roller 122, avoiding the rubber sleeve 331 from piling up at the same position of the winding roller 122 and affecting its use. The conductive ring 330 and the annular seat 320 are rotatably connected, so that when the winding roller 122 rotates, the conductive ring 330 will also rotate on the annular seat 320, avoiding the wire from being twisted and broken due to the rotation of the winding roller 122, causing damage.
