The device combines the installation mechanism and the sealing mechanism, which greatly improves the convenience of use and safety protection. The installation mechanism allows the electric couple part to be stably installed inside the armored shell, which is convenient for users to install and Disassembly operation, at the same time, the sealing mechanism realizes effective sealing of the bottom of the thermocouple part through the coordinated action of the telescopic spring, sliding rod, connecting rod and sealing cover, prevents the invasion of external substances, and ensures the stability and accuracy of the thermocouple. The side frame serves as the fixed basis of the sealing mechanism to ensure the stability of the entire mechanism. The telescopic spring provides elastic force so that the sliding rod can move up and down smoothly when needed. The rotating connection design of the sliding rod and the connecting rod allows the sealing cover to flexibly cover or leave the bottom ring, which is convenient for adjusting the exposure state of the thermocouple part. This design not only simplifies the operation process, but also improves work efficiency.

[0009] As a preferred technical solution, a support rod is fixedly installed on the top of the sliding rod, and the top of the support rod passes through the side frame. Firstly, the addition of the support rod enhances the stability of the sliding rod. Since the top of the support rod passes through the side frame, it can provide additional support for the sliding rod to prevent the sliding rod from shaking or shifting during movement, thereby ensuring that the sealing cover can accurately and stably cover or leave the bottom ring. Secondly, the through-penetration design of the support rod allows the user to operate the sliding rod more conveniently.

At the same time, the overall cross-sectional shape of the interior of the side frame is also set to a rectangle to match the shape of the slide bar. This design not only enhances the structural strength of the side frame, but also ensures that the slide bar slides stably inside the side frame without shaking or deflection. In addition, the outer surface of the slide bar and the inner wall of the side frame are fixedly connected with wear-resistant gaskets. The wear-resistant gasket is a material with high wear resistance, which can effectively reduce the friction between the slide bar and the side frame and reduce the degree of wear.

The adjusting rod, as a key component connecting the adjusting plate and the limit plate, acts as a bridge. The outer end of the adjusting rod is fixedly installed with an adjusting plate. The user can conveniently control the movement of the adjusting rod by operating the adjusting plate, thereby realizing the operation of the limit plate. The design of the adjusting plate enables the user to control and operate the installation mechanism more intuitively. The outer surface of the adjusting plate is usually designed with an anti-slip texture or a handle to facilitate the user to grasp and operate.

[0013] As a preferred technical solution, an adjustment guide plate is rotatably connected to the upper end of one side of the armored shell, and the overall shape of the adjustment guide plate is set to an ellipse. The outer side of the adjustment guide plate and the inner side of the adjustment plate are fit-connected. The overall shape of the adjustment guide plate is set to an ellipse. This design enables the adjustment guide plate to rotate within a certain range and has good mechanical properties and stability. At the same time, the outer side of the adjustment guide plate is fit-connected to the inner side of the adjustment plate. This connection method ensures a close fit between the adjustment guide plate and the adjustment plate, and can achieve effective transmission and guiding effects.

[0016] First, the device realizes convenient installation and disassembly of the thermocouple in the armored shell through a carefully designed installation mechanism. When the thermocouple is not plugged in, the limit spring drives the limit plate to move inward, pushing the limit arc plate to fit the annular limit groove to achieve stable clamping. When maintenance is required, the adjustment armrest is rotated to drive the adjustment guide plate to rotate, and then the adjustment plate and the adjustment rod are pushed, so that the connecting shaft drives the limit plate to move outward, the limit arc plate is separated from the annular limit groove, and the thermocouple part can be easily pulled out. This design makes the entire disassembly and assembly process simple and fast, greatly improves the convenience of disassembly and assembly of the device, and meets the needs of users in practical applications;

[0017] Second, by setting up a sealing mechanism, the device can conveniently adjust the switching state of the sealing cover. During normal use, the limit spring drives the slide bar to move upward, driving the connecting rod and the sealing cover to cover the bottom ring, thereby achieving bottom sealing and providing good protection. When it is necessary to expose the bottom of the electric couple part, it is only necessary to pull the sealing cover and rotate it, and the limit spring can withdraw the slide bar to expose the electric couple part. The operation is simple and quick. This design greatly improves the ease of use of the device, meets the user's needs for quickly adjusting the sealing cover in actual applications, and ensures the sealing and safety of the device.

At this time, the limit spring 52 can assist in pulling the sliding rod 53 upward to the inside of the side frame 51, and the sliding rod 53 can be pulled upward to drive the connecting rod 54 upward. The sealing cover 55 can be pulled to cover the outer side of the bottom ring 4 by the upward movement of the connecting rod 54. At this time, the sealing cover 55 can assist in sealing and covering the bottom of the armored shell 1. The sealing cover 55 and the bottom ring 4 cooperate to seal, which can play a better protective role. When it is necessary to adjust the exposure of the electric couple part 3, the sealing cover 55 can be separated from the outer side of the bottom ring 4 by pulling the sealing cover 55, and the sealing cover 55 is separated from the bottom ring 4. Then, the connecting rod 54 is twisted to drive the sealing cover 55 to rotate away from the bottom ring 4, and the limit spring 52 is reset to withdraw the sliding rod 53. At this time, the bottom of the electric couple part 3 can be exposed, so that the device can more quickly and conveniently adjust the switch separation of the sealing cover 55, which can further improve the overall convenience of use of the device.
