Since people began to use temperature for measurement in the early 17th century, with the continuous development of technology, the types and performance of temperature sensors have been greatly improved.

[0003] During the manufacturing process, temperature sensors are typically installed using simple threaded connections, resulting in poor sealing. However, for temperature sensors used in special environments, this is insufficient to meet the requirements, necessitating higher sealing performance. Therefore, a sealed ground temperature sensor structure is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealed ground temperature sensor structure includes a tube body, with a set of sealing mechanisms provided at both ends of the tube body;

[0008] Each sealing mechanism includes a clamping nut, a plug assembly, a plug housing, and a retaining ring. The outer circular sidewall of the plug housing is stepped. The inner circular sidewall of the tube has a stepped groove near the port for the plug housing to slide into. The retaining ring is threaded to the insertion end of the outer circular sidewall of the plug housing. The outer circular sidewall of the plug assembly is also stepped.

[0009] Preferably, each anti-loosening mechanism includes a fixed ring and an anti-loosening ring. The fixed ring is fixedly sleeved on the outer circumferential sidewall of the pipe body, and the anti-loosening ring is slidably sleeved on the outer circumferential sidewall of the pipe body. The anti-loosening ring is located between the fixed ring and the clamping nut. The anti-loosening ring and the fixed ring are interconnected by multiple elastic telescopic rods. The anti-loosening ring has multiple first teeth arranged in a ring on the side near the clamping nut, and multiple second teeth arranged in a ring are fixedly arranged at the port position near the clamping nut. Both the first teeth and the second teeth are ratcheted, and when the first teeth and the second teeth mesh with each other, they can only rotate in one direction, and the direction of rotation is the same as the thread tightening direction of the clamping nut.

[0010] Preferably, the outer circular sidewall of the clamping nut is provided with multiple transversely arranged anti-slip grooves.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-3 The structure of a sealed ground temperature sensor shown includes a tube body 1, and a set of sealing mechanisms are provided at both ends of the tube body 1.

[0024] Each sealing mechanism includes a clamping nut 2, a plug assembly 3, a plug housing 4, and a retaining ring 5. The outer circular sidewall of the plug housing 4 is stepped, and the inner circular sidewall of the tube body 1 has a stepped groove near the port for the plug housing 4 to slide into. Figure 1 As shown, the outer wall of the plug housing 4 is multi-segmented stepped, with each segment having a stepped groove. The bottom of the stepped groove is inclined, and the corresponding installation position of the outer wall of the plug housing 4 is also inclined, improving the sealing performance of the plug housing 4 when installed in the tube body 1. The retaining ring 5 is threadedly connected to the insertion end of the outer circular side wall of the plug housing 4. The outer circular side wall of the plug assembly 3 is also stepped. The end face of the plug housing 4 has a stepped hole for the plug assembly 3 to slide into. The outer end of the plug assembly 3 has a protruding cylinder. The clamping nut 2 is a round cap shape and is fitted onto the end of the tube body 1 and threadedly connected to the tube body 1. The bottom wall of the clamping nut 2 has a round opening for the cylinder to pass through. Figure 1As shown, the outer diameter of the cylinder is smaller than the maximum diameter of the plug assembly 3, which facilitates the clamping nut 2 to clamp the plug assembly. The clamping parts of the clamping nut 2 and the plug assembly 3 are both inclined, which improves the sealing between the clamping nut 2 and the plug assembly 3. The outer circular side wall of the tube body 1 is provided with two sets of anti-loosening mechanisms to prevent the clamping nut 2 from loosening. The outer end cylinder of the plug assembly 3 is sealed with AB glue. The internal components of the sensor, such as the circuit board, are located in the tube body 1.

[0025] like Figure 1 and Figure 3 As shown, each anti-loosening mechanism includes a fixed ring 6 and an anti-loosening ring 7. The fixed ring 6 is fixedly sleeved on the outer circumferential side wall of the pipe body 1, and the anti-loosening ring 7 is slidably sleeved on the outer circumferential side wall of the pipe body 1. The anti-loosening ring 7 is located between the fixed ring 6 and the clamping nut 2. The anti-loosening ring 7 and the fixed ring 6 are interconnected by multiple elastic telescopic rods 8. The side of the anti-loosening ring 7 near the clamping nut 2 is fixedly provided with multiple first teeth 9 arranged in a ring, and the end position of the clamping nut 2 near the end is fixedly provided with multiple second teeth 10 arranged in a ring. The first teeth 9 and The second tooth 10 is ratcheted, and when the first tooth 9 and the second tooth 10 are engaged, they can only rotate in one direction. The direction of rotation is the same as the tightening direction of the thread of the clamping nut 2. After the clamping nut 2 is tightened, the first tooth 9 and the second tooth 10 are engaged to prevent the second tooth 10 and the clamping nut 2 from rotating in the opposite direction, thereby preventing the clamping nut 2 from loosening and making it easy for people to use. When disassembly is required, the anti-loosening ring 7 and the first tooth 11 are pulled toward the fixed ring 6 to separate the first tooth 11 and the second tooth 10, and then the clamping nut 2 is disassembled by rotating in the opposite direction.

[0026] like Figure 1 and Figure 2 As shown, the outer circular sidewall of the clamping nut 2 has multiple transversely arranged anti-slip grooves, which facilitates the tightening of the clamping nut 2.

[0027] like Figure 1 As shown, a first plug seal 11 is provided in the middle of the outer side wall of the plug housing 4. The two sides of the first plug seal 11 abut against the retaining ring 5 and the outer side wall of the plug housing 4, respectively, which facilitates the improvement of the sealing between the plug housing 4 and the inner side wall of the tube body 1.

[0028] like Figure 1 As shown, a second plug seal 12 is fitted in the middle of the outer circular side wall of the plug assembly 3. The two sides of the second plug seal 12 are tightly abutted against the plug housing 4 and the plug assembly 3, respectively, which facilitates the improvement of the sealing between the plug assembly 3 and the plug housing 4.

[0029] Meanwhile, the outer wall of the plug housing 4 is in close contact with the inner wall of the tube body 1, and the outer wall of the plug assembly 3 is in close contact with the inner wall of the plug housing 4, further improving the sealing performance of the device.

[0030] During installation, the first annular plug is first placed on the outside of the plug housing. Then, the retaining ring is threaded onto the insertion end of the plug housing and tightened. Next, the insertion end of the plug housing and the retaining ring are inserted into the tube, and the outer end of the plug housing is inserted into the stepped groove and makes tight contact. Then, the second annular plug is placed on the plug assembly, and the plug assembly is inserted into the stepped hole of the plug housing. The second plug abuts tightly against the inner wall of the stepped hole. Finally, the clamping nut is placed on the end of the tube and the cylinder passes through the round opening on the clamping nut. The clamping nut is then tightened to the tube. The clamping nut presses against the plug assembly and the plug housing to achieve a seal. This method effectively improves the sealing effect and meets people's usage needs. After the clamping nut is tightened, the first and second teeth mesh, preventing the second teeth and the clamping nut from rotating in opposite directions, thereby preventing the clamping nut from loosening and facilitating use.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
