Temperature sensor and sheath structure for automobile exhaust detection

Abstract

The invention provides a temperature sensor for automobile exhaust detection and a sheath structure, relates to the field of sensors, and aims to solve the problems that a machine sheath of an existing temperature sensor for automobile exhaust detection is not convenient to mount when in use, the firmness of the sheath cannot be conveniently controlled and enhanced, and the sheath is easily damaged after being heated. The main body is a temperature sensor body, the bottom of the main body is provided with two hexagonal plates, and two sides of the main body are provided with two moving members. After the main body is unlimited and moves upwards, the connecting piece can move in the sliding groove in a guiding mode, due to the fact that the sliding groove is arranged in an inclined mode, the connecting piece can push the moving piece, when the moving distance of the main body received by power of the spring is larger, the clamping strength of the connecting piece is larger, and then the main body sheath is fixed in an auxiliary mode. After the device is heated after being used for a long time, the sheath of the main body cannot be damaged, and the service life of the device is longer.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more particularly relates to a temperature sensor and a sheath structure used for vehicle exhaust gas detection. Background technique [0002] When the vehicle exhaust gas is detected, it is usually necessary to measure the temperature. At this time, a temperature sensor and a sheath are required. [0003] For example, the application number: CN201410040039.6 relates to a special temperature sensor for automobile exhaust gas measurement and its preparation method, including a core wire, the core wire is covered with a sheath, the front end of the core wire is fixedly connected with a temperature detector, and the rear end of the core wire is fixed A wire is connected, the front end of the sheath is sleeved with a sleeve, the inner space formed between the sheath and the sleeve is filled with filler, and the front end of the sleeve is a closed structure. The preparation method solves the prob...
