Description

Technical Field

[0001] The utility model belongs to the technical field of engines and relates to a temperature sensor, in particular to an engine temperature sensor. Background Art

[0002] The interior of the car water temperature sensor is the engine water temperature sensor. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. It is generally installed on the water jacket of the engine block or cylinder head, in direct contact with the cooling water, thereby measuring the temperature of the engine cooling water.

[0003] The existing engine water temperature sensor includes a sensor, a shell, a junction box and a tube body. The sensor is fixedly installed in the tube body. The connection between the shell and the tube body is generally fixed with a single through hole. Under the impact of the water flow in the casing for a long time, the tube body outside the sensor is prone to shaking, resulting in instability in the data transmitted by the temperature sensor, thereby affecting the use of the temperature sensor. Summary of the invention

[0004] The purpose of the utility model is to provide an engine temperature sensor with good stability in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an engine temperature sensor, comprising a temperature sensor housing and a tube body, characterized in that the sensor housing is provided with a mounting groove for the tube body to extend into, the tube body is fixedly provided with a mounting seat, the temperature sensor housing is fixedly provided with two fixing seats, and the two fixing seats are arranged in an upper and lower structure, the mounting seat is fixedly provided with a plurality of positioning rods for positioning the fixing seats, each of the positioning rods is provided with two positioning assemblies, the positioning assembly is composed of a positioning piece and a connecting spring, the positioning rod is provided with a slot for the positioning assembly to be installed, one end of the positioning piece extends out of the slot, and the other end of the positioning piece extends into the slot and is connected to the connecting spring, the connecting spring enables the positioning piece to be extended and retracted on the positioning rod so that the tube body is fixed to the temperature sensor housing.

[0006] In the above-mentioned engine temperature sensor, there are four positioning rods, which are integrally formed with the mounting seat. The mounting seat is provided with openings for the positioning rods to pass through, and the diameter of the openings is the same as the diameter of the positioning rods.

[0007] In the above-mentioned engine temperature sensor, a threaded block is provided at the lower end of the pipe.

[0008] Compared with the prior art, the engine temperature sensor is provided with a positioning assembly between the temperature sensor and the tube body, so that the tube body is more stable during installation and is easy to disassemble and replace after long-term use.
