Detailed Implementation

[0021] like Figures 1-7 As shown, the present invention provides a deep-hole pre-embedded temperature element wire support device, comprising a support body 1, a locking core 2, a clamping nut 3, a pressure cap 4, and a spring 5. The support body 1 includes a top hole 101 and a bottom hole 102, which are coaxial and connected. The locking core 2 includes a center hole I 201, and the clamping nut 3 includes a center hole II 303. The locking core 2 is connected inside the top hole 101, and the clamping nut 3 is connected inside the top hole 101. The locking core 2 abuts against the top hole 101 and the clamping nut 3. Between the top hole 101, the center hole I 201 and the center hole II 303 are coaxial. The temperature element wire passes through the bottom hole 102, the center hole I 201 and the center hole II 303. The support body 1, the locking core 2 and the clamping nut 3 are all located inside the temperature element mounting hole. The temperature element wire is snapped into the center hole I 201. The pressure cover 4 is fixedly connected to the port of the temperature element mounting hole. The temperature element wire passes through the pressure cover 4. The spring 5 is sleeved on the outside of the temperature element wire. The spring 5 is pressed between the clamping nut 3 and the pressure cover 4.

[0022] The locking core 2 has a concave arc section 202 in the middle along its length. The concave arc section 202 is located in the middle of the central hole I 201. The concave arc section 202 is coaxial with and connected to the central hole I 201. The inner diameter of the concave arc section 202 is smaller than the inner diameter of the central hole I 201. The inner wall of the concave arc section 202 is engaged with the outer wall of the temperature element wire.

[0023] The inner wall of the top hole 101 is provided with an internal thread. The clamping nut 3 includes a straight section I301 and a hexagonal part I302. The center hole II303 passes through the straight section I301 and the hexagonal part I302. The outer wall of the straight section I301 is provided with an external thread I3011. The external thread I3011 is connected to the internal thread of the top hole 101. The hexagonal part I302 is located on the outside of the top hole 101.

[0024] The bottom hole 102, center hole I 201 and center hole II 303 have the same inner diameter. The inner diameter of the bottom hole 102, the center hole I 201 and the center hole II 303 are all larger than the outer diameter of the temperature element wire.

[0025] The outer diameters of the support body 1, the locking core 2, and the clamping nut 3 are all smaller than the inner diameter of the mounting hole of the temperature element.

[0026] The outer diameter of the locking core 2 is smaller than the inner diameter of the top hole 101.

The locking core 2 can move freely within the support body 1 without any distinction between positive and negative when not subjected to external force. After the support body 1 and the clamping nut 3 are connected, they compress the locking core 2, causing the concave arc section 202 to deform inward, thereby achieving the snap-fit ​​fixation of the temperature element wire. The installation positions of the support body 1, locking core 2, and clamping nut 3 on the wire are determined according to the depth of the temperature element mounting hole. The temperature sensor head of the temperature element should be placed on the bottom wall of the mounting hole.

Finally, the pressure cap 4 is connected to the internal thread of the temperature element mounting hole. It should be noted that after installation, the spring 5 should be in a compressed state to ensure that the present invention provides support for the temperature element wire.

[0030] Normally, spring 5 and pressure cap 4 are included with the temperature element at the factory and can be used directly during installation.

[0031] The temperature element described in this utility model is a thermocouple or resistance temperature detector (RTD) commonly used in the industrial field. Variations in the rectangular type or specific model of the temperature element do not affect the understanding of the technical solution of this utility model by those skilled in the art.

[0032] This invention forms a fixed fulcrum on the wire of the temperature element by setting the support body 1, the locking core 2, and the clamping nut 3. This allows the temperature element to be stably connected in mounting holes of different depths without adding a spring 5, ensuring that the temperature element is installed in place and preventing misalignment during use. This invention is easy to connect and stable to install. It can achieve stable installation of the temperature element in mounting holes of different depths, avoiding temperature fluctuations or inaccuracies caused by adding a spring or unstable temperature element mounting, and ensuring accurate temperature measurement.
