Description

A waterproof armored thermocouple Technical Field

[0001] This utility model relates to the field of thermocouple technology, and in particular to a waterproof armored thermocouple. Background Technology

[0002] Armored thermocouples are temperature sensors with numerous advantages, such as a wide temperature measurement range, fast response speed, small dynamic error, flexible installation, high mechanical strength, and good pressure resistance. They can be used with digital instruments, recording and regulating instruments, PLCs, data acquisition units, or computers. As a new generation of temperature sensors, they are widely used in various sectors including metallurgy, petroleum, chemical, power, light industry, textiles, food, national defense, and scientific research.

[0003] A search revealed an existing patent (publication number: CN222419303U) that discloses "an armored thermocouple, comprising an armored body, wherein a thermocouple is disposed within the armored body, characterized in that the armored body has a placement cavity, a threaded hole, an external threaded plate is internally threaded and connected to the threaded hole, an mounting assembly for placing the thermocouple plate portion is provided on the top of the external threaded plate, an inner cavity is provided below the threaded hole, and a clamping assembly is provided within the external threaded plate that can clamp the thermocouple wire end portion after the external threaded plate is moved downward. By placing the thermocouple plate portion onto the inner cavity of the cylinder, during the rotation of the cylinder, the thermocouple wire end portion is gradually clamped by the abutment plate, thus maintaining the thermocouple in the position within the armored body and preventing it from loosening."

[0004] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: Although the patented technology can clamp and fix the thermocouple through the set clamping components and mounting components to prevent the thermocouple from loosening, the thermocouple will age and corrode after long-term use in a humid environment, which will affect the stable operation of the thermocouple plate. Therefore, those skilled in the art provide a waterproof armored thermocouple to solve the problems mentioned in the background technology. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof armored thermocouple. By rotating a flip cover on the upper surface of the outer shell, the flip cover can be opened or closed more conveniently. The rubber ring and sealing gasket can improve the waterproof effect of the thermocouple, thereby enabling the thermocouple to operate stably.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A waterproof armored thermocouple includes a housing body, a flip cover rotatably disposed on one side of the upper end face of the housing body, an embedding groove opened on the outer side of the upper end face of the housing body, an embedding block fixedly disposed at the midpoint of one side of the lower end face of the flip cover, and a knob rotatably embedded at the midpoint of the upper end of one side of the housing body.

[0008] A sealing gasket is embedded inside the lower midpoint of the outer shell body. Four support columns are fixedly installed on the upper outer side of the inner bottom surface of the outer shell body. Mounting plates are installed on the upper ends of the four support columns. Rotating rods are rotatably embedded at the upper midpoint of both sides of the mounting plate. Rubber blocks are installed on the upper ends of the inner walls on both sides of the mounting plate.

[0009] Furthermore, a fixing block is movably embedded in the upper midpoint of the inner wall of one side of the outer shell body. The fixing block is rotatably sleeved on the outer surface of one end of the knob. The embedding block is embedded in one side of the upper end face of the outer shell body. The fixing block and the embedding block are fitted together.

[0010] Furthermore, a rubber ring is embedded inside the embedding groove, the upper end face of the outer shell is movably embedded at the midpoint of the lower end face of the flip cover, and a connection port is embedded on one side of the outer shell.

[0011] Furthermore, the two rubber blocks are respectively rotatably sleeved on the outer surface of one end of the two rotating rods, and the two rubber blocks are respectively movably embedded in the upper ends of both sides of the inner wall of the mounting plate.

[0012] Furthermore, all four support columns penetrate both sides of the upper surface of the mounting plate, and the lower surface of the mounting plate is embedded at the midpoint of the inner bottom surface of the outer shell body.

[0013] Furthermore, a thermocouple body is embedded at the midpoint of the upper surface of the mounting plate, and the lower end of the thermocouple body penetrates through the midpoint of the lower surface of the outer shell.

[0014] Furthermore, an installation block is fixedly sleeved on the lower end of the outer plate of the thermocouple body, and a nut is threaded onto the outer surface of the installation block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a waterproof armored thermocouple. After opening an embedding groove on the upper end face of the outer shell, a rubber ring can be embedded in the embedding groove. After the flip cover is rotated and set on one side of the upper end face of the outer shell, the rotating flip cover and the upper end of the outer shell can be fitted together. The rubber ring can provide a seal for the fitted connection between the outer shell and the flip cover. At the same time, after embedding the embedding block fixed on the lower end face of the flip cover into the upper end face of the outer shell, the knob set in the outer shell can be rotated, so that the knob drives the fixed block and the embedding block to fit together, thereby fixing the flip cover. It is easier to open the flip cover and connect the thermocouple circuit. The rubber ring can also provide a waterproof effect for the thermocouple.

[0017] 2. The waterproof armored thermocouple proposed in this utility model, after fixing four support columns to the inner bottom surface of the outer shell body, can install and fix the mounting plate on the upper end surface of the four support columns. At the same time, after the lower end of the mounting plate is fitted and connected to the inner bottom surface of the outer shell body, the thermocouple body embedded at the midpoint of the upper end surface of the mounting plate can better penetrate the mounting plate and the outer shell body. The two rotating rods and rubber blocks set in the mounting plate can conveniently clamp and fix the thermocouple body. Meanwhile, after the sealing gasket is embedded in the lower end of the outer shell body, it can fit with the outer surface of the thermocouple body, thereby further improving the waterproof effect of the thermocouple.

[0028] Specifically, after the flip cover 1 is rotated and positioned on one side of the upper end face of the outer shell body 5, the flip cover 1 and the upper end of the outer shell body 5 can be fitted together, thereby providing a sealing and protective function for the inside of the outer shell body 5. After the embedding groove 7 is opened on the upper end face of the outer shell body 5, the rubber ring 13 can be placed between the flip cover 1 and the outer shell body 5 to seal the thermocouple. At the same time, after the embedding block 14 fixedly set on the lower end face of the flip cover 1 is embedded into one side of the upper end face of the outer shell body 5, the fixing block 16 and the knob 15 set on the upper end of one side of the outer shell body 5 can fix the embedding block 14, thereby making it easier to open or fix the flip cover 1. After the sealing gasket 9 is embedded in the lower end of the outer shell body 5, the waterproof effect of the outer shell body 5 on the thermocouple can be further improved.
