However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figure 1-5 As shown, this embodiment provides an adjustable instrument base, including a docking block 2 that connects to a connecting pipe 1 on a pipeline. A first flange 3 is provided around the docking block 2, and a connecting pipe 4 is provided in the middle of the docking block 2. The docking is secured by the first flange 3, facilitating later assembly and disassembly. A flange connects the docking block 2 and the connecting pipe 1, with a sealing gasket between them to ensure a good overall sealing effect. The following is an improvement of this invention: the sleeve 5 is improved. An adjustable-length sleeve 5 is connected to the outer end of the connecting pipe 4. The sleeve 5 includes several sub-pipes 6 and one end pipe 7. Both the sub-pipes 6 and the end pipe 7 are made of thermally conductive material, providing better thermal conductivity and making the temperature detected by the temperature instrument more accurate. The surfaces of the sub-pipes 6 and the end pipe 7 are coated with an anti-corrosion layer, thus preventing corrosion and extending their service life.

[0019] Several sub-tubes 6 are connected end-to-end to form the main body of the sleeve. The length of the main body of the sleeve can be adjusted by adding or removing sub-tubes. The end tube 7 is threaded to the outer end of the main body of the sleeve, which facilitates disassembly and assembly. The mating block 2 is also provided with an installation tube 8 that mates with the outer port of the connecting tube 4, which facilitates the installation of the temperature instrument and the base. The port of the installation tube 8 is provided with a second flange 9 with a diameter smaller than that of the first flange 3, so as not to cause inconvenience to the fixing of the first flange 3.

[0020] The connecting pipe 4 has an inwardly recessed first mating cavity 10 at its mating end, and a first insertion pipe 11 inserted into the first mating cavity 10 at one end of the sub-pipe. The outer wall of the first insertion pipe 11 has a first external thread structure 12, and the inner wall of the first mating cavity 10 has a first internal thread structure 13 that cooperates with the first external thread structure 12. This makes the connecting pipe 4 and the sub-pipe connected by threads, which facilitates assembly and disassembly without the need for tools. Furthermore, the bottom of the first mating cavity 10 has a first sealing ring 14 for sealing the connection between the connecting pipe 4 and the sub-pipe 6. This seals the connection between the connecting pipe 4 and the sub-pipe 6, ensuring a good sealing effect and making it suitable for high-pressure environments.

[0021] The other end of the sub-tube 6 is provided with a second docking cavity 15, and the first insertion tube 11 on the connected sub-tube 6 is inserted into the second docking cavity 15. The second docking cavity 15 is provided with a second internal thread structure 16 that mates with the first external thread structure. The sub-tubes 6 are connected by threads, which facilitates assembly and disassembly without the need for tools and allows for free assembly and mating. The second docking cavity 15 is provided with a second sealing ring 18 for sealing the connection between the sub-tubes 6, ensuring a good sealing effect and making it suitable for high-pressure environments.

[0022] The end tube 7 is provided with a second insertion tube 17 that is inserted into the second docking cavity 15. The second insertion tube 17 is threadedly connected to the second docking cavity 15, and a third sealing ring 19 is provided between the two. This facilitates assembly and disassembly without the need for tools.

[0023] The outer surfaces of the sub-tube 6 and end tube 7 are provided with anti-slip texture 23, which facilitates hand rotation and assembly. The ends of both the first insertion tube 11 and the second insertion tube 17 are provided with guide portions, facilitating insertion into the first mating cavity and the second mating cavity 15. Both the first flange 3 and the second flange 9 are provided with mounting holes 21. The bottom of the first flange 3 is provided with a sealing groove 22 for accommodating the gasket.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Working principle: The connecting block 2 is fixed to the connecting pipe 1 via a flange. An adjustable sleeve 5 is connected to the outer end of the connecting pipe, allowing adjustment of the insertion depth into the pipe to accommodate different types of pipes and ensure the temperature measuring instrument's insertion depth meets temperature measurement requirements. The sleeve 5 is formed by connecting several sub-pipes 6 end-to-end. The length of the sleeve 5 can be adjusted by adding or removing sub-pipes 6. The end pipe 7 is then installed on the sleeve 5. Sealing rings are installed at each connection point for sealing, resulting in a good sealing effect after the sleeve 5 is connected.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
