Description

Technical Field

[0001] The utility model relates to the technical field of metal thermocouple temperature measurement, in particular to a temperature measuring device for low-cost metal thermocouple welding. Background Art

[0002] A thermocouple is a temperature-sensing element and a primary instrument that directly measures temperature. Two conductors or semiconductors, A and B, made of different materials, are welded together to form a closed circuit. When a temperature difference exists between the two attachment points 1 and 2 of conductors A and B, an electromotive force is generated between them, thus forming a current of varying magnitude in the circuit. This phenomenon is called the thermoelectric effect, and thermocouples utilize this effect to operate. Currently, during the processing of metal thermocouples, the hot electrode needs to be welded and fixed to the thermocouple, and the welding temperature must be measured. Common temperature measuring devices have a fixed structure, and workers are unable to adjust the length of the temperature measuring device according to usage, which reduces the practicality of the temperature measuring device. To address this issue, we have proposed a temperature measuring device for low-cost metal thermocouple welding. Utility Model Content

[0003] To address the above-mentioned issues, the present invention provides a temperature measuring device for low-cost metal thermocouple welding. This device addresses the current problem of requiring the thermocouple to be welded and fixed to the thermocouple during the metal thermocouple processing process, and measuring the welding temperature. The conventional temperature measuring device has a fixed structure, making it impossible for the operator to adjust the length of the temperature measuring device according to the usage, thereby reducing the practicality of the temperature measuring device.

[0004] The utility model provides a temperature measuring device for welding low-cost metal thermocouples, comprising a first shell, a fixed plate provided on one side of the first shell, a motor provided on one side of the fixed plate, a rotating shaft of the motor passing through the fixed plate and fixedly connected to a threaded rod, a movable block provided on the threaded rod, connecting rods provided on both sides of an end of the movable block away from the motor, a side of the connecting rod away from the movable block is fixedly connected to the second shell, a mounting plate provided in the second shell, an infrared thermometer provided on the side of the mounting plate away from the first shell, a transparent glass window matching the infrared thermometer provided on the second shell, and a display screen provided on the side wall of the first shell close to the motor.

[0005] In the above solution, the first shell is provided with control buttons below the display screen.

[0006] In the above solution, a handle is provided below the side of the first shell close to the motor.

[0007] In the above solution, a lithium battery is provided in the handle.

[0008] In the above solution, a motor control key is provided on the upper end of the handle, and a plurality of anti-slip grooves arranged at equal distances are provided on the side of the handle close to the motor control key.

[0009] In the above solution, the first shell is provided with a heat dissipation window on the side wall of the motor.

[0010] The advantages and beneficial effects of the present invention are as follows: the present invention provides a temperature measuring device for welding low-cost metal thermocouples, wherein the movable block on the threaded rod can reciprocate horizontally on the threaded rod. During the movement of the movable block, the movable block pushes the connecting rod to move, and the second shell is also moved by the transmission of the connecting rod. By adjusting the distance between the first shell and the second shell, the overall length of the temperature measuring device is also changed. The infrared thermometer can detect the temperature of the welding point, and the display can display the temperature tested by the infrared thermometer, thereby making it easier for staff to observe temperature changes. This temperature measuring device has a simple structure, is easy to operate, has a good temperature measurement effect, is easy to display test results, and is easy to adjust the overall length of the temperature measuring device, effectively improving the practicality of the temperature measuring device.
