Abstract

The invention discloses a temperature sensing probe for rapid sensing and high temperature resistance. The temperature sensing probe comprises a shell, a control unit, a transmission unit, a fixing unit and a springback unit, the shell is tubular, a connecting sleeve is fixedly installed on the outer side of the top of the shell, the bottom of the shell is in threaded connection with a contact head, and a slotted hole is formed in the middle of the shell; the control unit comprises grips, first connecting rods, second connecting rods, first connecting pieces, second connecting pieces and pin rods, the grips are installed on the left side and the right side of the connecting sleeve in a bilateral symmetry mode, the first connecting rods are arranged in arc-shaped grooves of the grips respectively, and the grips are rotatably connected with the first connecting rods through the pin rods; and according to the temperature sensing probe for rapid sensing and high temperature resistance, thetemperature sensor body can be effectively protected, and meanwhile, the temperature sensing probe can rapidly stretch out and draw back and rapidly sense the temperature when sensing the temperature.

Description

technical field [0001] The invention relates to the technical field of temperature-sensing probes, in particular to a temperature-sensing probe for rapid sensing of high temperature resistance. Background technique [0002] Temperature probes are also called "temperature sensors". Temperature sensors are often called temperature probes or probes in the market. They refer to stainless steel or other heat-conducting materials used for temperature detection elements; [0003] Commonly used temperature sensors can be divided into two types, contact type, the detection part of the contact type temperature sensor has good contact with the measured object, also known as thermometer, non-contact type, its sensitive element does not contact with the measured object, and It is called non-contact temperature measuring instrument, which can be used to measure the surface temperature of moving objects, small targets and objects with small heat capacity or rapid temperature changes (trans...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used temperature-sensing probe adopts the touch-type method to sense temperature. Two different metal materials are welded together. When the temperature changes, different potentials are generated at both ends, and the corresponding temperature change is obtained through the change of the potential. Now Some temperature probe shells mostly adopt a straight cylindrical structure, and the temperature sensor needs to be extended as a whole for temperature sensing. The connection material at the temperature sensor is prone to aging due to high temperature, and the body of the temperature sensor cannot be effectively protected. At the same time, the extension and retraction speed of the existing temperature sensor is relatively slow, and the temperature sensing cannot be performed quickly.
