Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensors, and in particular relates to a temperature sensor with a protective structure for an engineering vehicle. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. It is the core part of a temperature measuring instrument and has many varieties. It can be divided into two categories: contact and non-contact according to the measurement method, and can be divided into two categories: thermal resistors and thermocouples according to the characteristics of sensor materials and electronic components.

[0003] An existing temperature sensor is a device that can sense temperature and convert it into a usable output signal. However, during the use of the temperature sensor probe, a large amount of dust and debris are easily adhered to the outer surface of the sensor probe. These dust and debris may cause errors in the sensor probe's measurement of the surrounding temperature, thereby making the measurement result inaccurate. In addition, the sensor probe is easily damaged or even destroyed by external impact or collision during use. Therefore, a temperature sensor with a protective structure for engineering vehicles is needed to solve the above problems. Utility Model Content

[0006] By setting the above structure, the protective ring is sleeved on the outer surface of the sensor probe to realize the connection between the protective device and the sensor probe. At this time, the protective ring can protect the sensor probe so that the sensor probe will not directly contact the external dust and debris, thereby preventing the dust and debris from adhering to the outer surface of the sensor probe, thereby causing deviations in the measurement data. It can also prevent the impact or collision from the outside from directly acting on the sensor probe, causing damage or even damage to the sensor probe. When the sensor probe is not in use, the scraper will clean the outer surface of the protective ring, so that the dust and debris adhering to the outer surface of the protective ring can be cleaned, so that the outer surface of the protective ring can be kept clean and tidy.

[0007] As a preferred solution, a data wire is fixedly connected to the bottom of the connection end.

[0008] As a preferred solution, a first connecting tube is fixedly connected to the outer surface of the data wire.

[0009] As a preferred solution, one side of the outer surface of the first connecting pipe is fixedly connected with a fixing bolt.

[0010] As a preferred solution, a second connecting pipe is fixedly connected to one side of the outer surface of the fixing bolt.

[0011] As a preferred solution, the protective ring is connected to the sensing probe sleeve.

[0012] As a preferred solution, the scraper is fixedly connected to the swivel.

[0013] By arranging the annular groove, the swivel, the rotating slide groove and the sealing plate, the annular groove and the rotating slide groove can respectively provide limiting and guiding functions for the swivel and the sealing plate, so that the rotation of the swivel and the sealing plate is more stable and smooth.

At this time, the protective ring can protect the sensor probe, so that the sensor probe will not directly contact the dust and debris from the outside, thereby preventing the dust and debris from adhering to the outer surface of the sensor probe, thereby causing deviations in the measurement data. It can also prevent the impact or collision from the outside from directly acting on the sensor probe, causing damage or even destruction thereof. When the sensor probe is not in use, the scraper cleans the outer surface of the protective ring, so that the dust and debris adhering to the outer surface of the protective ring can be cleaned, and the outer surface of the protective ring can be kept clean and tidy.
