It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Example 1: As Figures 1-13As shown, this utility model provides an intelligent temperature transmitter, including a temperature transmitter body 1. A first fixing block 2 is fixedly connected to the outer surface of the temperature transmitter body 1. A moving component 3 is disposed inside the first fixing block 2. The moving component 3 includes a first fixing box 301. A groove 302 is formed on the inner wall of the first fixing box 301. A first slider 303 is rotatably connected to the inner wall of the groove 302. A first helical gear 304 is fixedly connected to the outer surface of the first slider 303. A lead screw 308 is fixedly connected to the outer surface of the first helical gear 304. A threaded shaft 309 is threadedly connected to the outer surface of the lead screw 308. A second fixing box 310 is fixedly connected to one side of the outer surface of the first fixing box 301. A sliding shaft 314 is fixedly connected to the other side of the outer surface of the first fixing box 301. A rotating shaft 305 is rotatably connected to the inner wall of the first fixing box 301. A second helical gear 306 is fixedly connected to one end of the rotating shaft 305. A handle 307 is fixedly connected to the other end of the rotating shaft 305. The outer surface of the first helical gear 304 and the second helical gear 306 are connected to the sliding shaft 306. The outer surfaces of 06 mesh with each other. The outer surface of the lead screw 308 moves through one side of the outer surface of the first fixed box 301 and extends to the outside. The inner wall of the sliding shaft 314 has a first sliding groove 315. The inner wall of the first sliding groove 315 is slidably connected to the second slider 316. The outer surface of the second slider 316 is fixedly connected to the outer surface of the threaded shaft 309. The outer surface of the threaded shaft 309 is slidably connected to the inner wall of the sliding shaft 314. The inner wall of the second fixed box 310 is fixedly connected to the fixed shaft 311 at the center. An elastic coil spring 312 is provided on the outer surface of the fixed shaft 311. One end of the elastic coil spring 312 is fixedly connected to the outer surface of the fixed shaft 311. A plurality of evenly arranged baffles 313 are provided on the inner wall of the second fixed box 310. A display 4 is provided on the inner wall of the temperature transmitter body 1. A first terminal 5 is provided on the outer surface of the temperature transmitter body 1. A second fixing block 6 is fixedly connected to one end of the threaded shaft 309. A temperature measuring end 12 is fixedly connected to the outer surface of the second fixing block 6. A thermal resistance wire 7 is provided on the inner wall of the temperature measuring end 12.

[0035] The overall effect of Embodiment 1 is that, in the specific use of the intelligent temperature transmitter, when it is necessary to measure the interior of an object, the operator first connects the connecting terminal 9 and the second wiring terminal 8. The connecting terminal 9 and the second wiring terminal 8 are electrically connected. Then, the operator rotates the handle 307, which drives the rotating shaft 305 to rotate. The outer surface of the rotating shaft 305 rotates along the inner wall of the first fixed box 301. At the same time, the rotating shaft 305 drives the second helical gear 306 to rotate. When the second helical gear 306 rotates, it drives the first helical gear 304 to rotate. When the first helical gear 304 rotates, it simultaneously drives the first slider 303 and the lead screw 308 to rotate. The outer surface rotates along the inner wall of the groove 302. Both the groove 302 and the first slider 303 are trapezoidal. When the lead screw 308 rotates, since the outer surface of the lead screw 308 is threadedly connected to the inner wall of the threaded shaft 309, the rotation of the lead screw 308 will drive the threaded shaft 309 to move along the threaded outer surface of the lead screw 308. When the threaded shaft 309 moves, it will drive the second slider 316 to slide along the inner wall of the first slide groove 315. At the same time, the outer surface of the threaded shaft 309 will slide along the inner wall of the slide shaft 314. When the threaded shaft 309 moves, it will drive the second fixed block 6 to move. When the second fixed block 6 moves, it will drive the temperature measuring end 12 to move. When the temperature measuring end 12 moves, it will drive the thermal resistance wire 7 to move. When the resistance temperature detector (RTD) wire 7 moves, its outer surface slides along the inner wall of the second fixed box 310, thereby moving the RTD wire 7 located inside the second fixed box 310. As the RTD wire 7 moves, its outer surface slides along the outer surface of the baffle 313. Simultaneously, the RTD wire 7 stretches the elastic coil spring 312, which rotates and stretches around the outer surface of the fixed shaft 311. During this stretching, the elastic coil spring 312 also drives the RTD wire 7 to slide along the inner wall of the second slide groove 11. When the temperature measuring end 12 moves to the appropriate position, the handle 307 is stopped, and the temperature value measured by the temperature measuring end 12 is transmitted through the RTD wire 7. The signal is sent to connector 9, then transmitted to second connector 8, and then to temperature transmitter body 1. Temperature transmitter body 1 amplifies, linearizes, and compensates for the temperature through its built-in signal processing circuit, converting it into a standardized electrical signal. This is a known technology and will not be explained in detail. The value is then displayed on display 4. This device uses a moving component 3 to move the threaded shaft 309, thereby moving the temperature measuring end 12. By moving the temperature measuring end 12 back and forth, it can measure different depths, solving the problem that different temperature transmitters are required for different measurement depths, resulting in poor versatility of temperature transmitters.

[0036] Example 2: As Figures 1-13As shown, the outer surface of the resistance thermometer 7 slides against the inner wall of the second fixing block 6, the outer surface of the resistance thermometer 7 slides against the inner wall of the second fixing box 310, and the outer surface of the resistance thermometer 7 slides against the outer surface of the baffle 313. The outer surface of the resistance thermometer 7 is fixedly connected to the other end of the elastic coil spring 312. A cover plate 10 is fixedly connected to the outer surface of the second fixing box 310. A second sliding groove 11 is opened on the outer surface of the cover plate 10. The outer surface of the resistance thermometer 7 slides against the inner wall of the second sliding groove 11. A connection end 9 is provided at one end of the resistance thermometer 7. A second wiring terminal 8 is provided on the outer surface of the temperature transmitter body 1. The connection end 9 is located inside the second wiring terminal 8.

[0037] The effect achieved by the entire embodiment 2 is that, during the specific use of the intelligent temperature transmitter, after the temperature measuring end 12 has finished measuring the measured item, the operator rotates the handle 307. The handle 307 will drive the threaded shaft 309 to move towards the temperature transmitter body 1. The threaded shaft 309 will drive the temperature measuring end 12 to move back. At this time, the tension of the thermal resistance wire 7 by the elastic coil spring 312 will gradually weaken. The elastic force of the elastic coil spring 312 will cause the thermal resistance wire 7 located between the temperature measuring end 12 and the elastic coil spring 312 to move into the interior of the second fixed box 310. The tension of the elastic coil spring 312 will cause the outer surface of the thermal resistance wire 7 to slide along the outer surface of multiple baffles 313. At the same time, the thermal resistance wire 7 will slide along the inner wall of the second fixed box 310. Through the tension of the elastic coil spring 312, the thermal resistance wire 7 will slide evenly along the outer surface of multiple baffles 313 inside the second fixed box 310, thereby preventing the thermal resistance wire 7 from being scattered messily on the outside of the intelligent temperature transmitter, thus improving the cleanliness of the intelligent temperature transmitter.

[0038] Working Principle: In practical use, when measuring the internal structure of an object, the operator rotates handle 307. Handle 307 drives the second helical gear 306 to rotate, which in turn drives the first helical gear 304. The first helical gear 304 then drives the lead screw 308 to rotate, which in turn drives the threaded shaft 309 to slide along the inner wall of the first sliding groove 315. The threaded shaft 309 then moves the temperature measuring end 12, which in turn moves the thermal resistance wire 7. The outer surface of the thermal resistance wire 7 slides along the inner wall of the second fixed box 310, simultaneously stretching the elastic coil spring 312 within the second fixed box 310. When stretched, the elastic coil spring 312 moves the thermal resistance wire 7 along the inner wall of the second fixed box 310. The inner wall of the slide 11 slides. When the temperature measuring end 12 moves to the appropriate position, the temperature measuring end 12 transmits the temperature value of the measured item to the temperature transmitter body 1 through the thermal resistance wire 7. After the detection is completed, the handle 307 is rotated in the opposite direction, which drives the threaded shaft 309 to move in the opposite direction. The reverse movement of the threaded shaft 309 will cause the thermal resistance wire 7 to gradually weaken the tension on the elastic coil spring 312. The tension of the elastic coil spring 312 will cause the outer surface of the thermal resistance wire 7 to slide along the outer surface of multiple baffles 313. The outer surface of the thermal resistance wire 7 will slide evenly along the outer surface of the baffles 313. By setting the moving component 3, the threaded shaft 309 is moved, thereby driving the temperature measuring end 12 to move. By moving back and forth, the temperature measuring end 12 can measure different measurement depths, thereby improving the versatility of the intelligent temperature transmitter.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
