Description
Technical Field
The utility model belongs to the technical field of the car, specific but reuse's sensor fixing device that says so.
Background
The development of the whole engine is a very complex process, and needs to be comprehensively considered from the aspects of performance, economy, reliability and the like. The temperature of main parts of the engine, such as a cylinder cover and an important position of an engine body, is an important parameter for predicting the reliability of the engine, and therefore, temperature measurement tests are very necessary in the development process of the engine. In the prior art, most of domestic host computer factories fix a temperature measuring sensor in a hole machined by a part in a gluing mode for temperature measurement when performing a temperature measurement test. Due to the long solidification time of glue and high technical requirement of gluing, the fixing mode of the sensor has the problems of low installation efficiency, easy water leakage of parts after installation and the like in the actual work; more importantly, after the fixing mode is adopted, the temperature sensor cannot be detached, and the resource is greatly wasted.
Therefore, it is important to design a sensor fixing device to stably and reliably fix the sensor on the part and make the sensor reusable.
Disclosure of Invention

The technical scheme of the utility model is explained as follows with the attached drawings:
a reusable sensor fixing device comprises a fixing joint 1, a connecting pipe 2, a fixing split A3 and a fixing split B; the fixed split A3 and the fixed split B are respectively fixed on two sides of the temperature measuring sensor protection tube; one end of the connecting pipe 2 is in threaded connection with one end of the fixed joint 1; the other end of the fixed joint 1 is in threaded connection with a temperature measurement part arranged on a temperature measurement sensor; the other end of the connecting pipe 2 is in threaded connection with a fixed split A3 and a fixed split B.
One end of the fixed joint 1 is provided with an external thread which is in threaded connection with a temperature measurement part arranged on the temperature measurement sensor, and the other end of the fixed joint is provided with an internal thread which is in threaded connection with the connecting pipe 2; the external thread and the internal thread are both 1/8 taper threads.
One end of the connecting pipe 2 is provided with an external thread which is in threaded connection with the internal thread end of the fixed joint 1, and the other end of the connecting pipe is provided with an internal thread which is in threaded connection with the external threads of the fixed split A3 and the fixed split B; the inside of the connecting pipe 2 is a hollow structure.
The fixed split A3 and the fixed split B are hollow and stepped and contact with the edge of the protective sleeve of the temperature sensor.
The utility model has the advantages that:
the device uses the threads as a connection mode to realize reliable and efficient installation of the sensor. The utility model discloses can solve the unable reuse of temperature sensor that traditional rubber coating method fixed sensor caused, cause the very big waste of resource, improve temperature measurement efficiency simultaneously.

Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. fixing the joint; 2. a connecting pipe; 3. fixing the split A; 4. and (4) fixing the split B.
Detailed Description
Referring to fig. 1, the fixing device for the reusable sensor comprises a fixed joint 1, a connecting pipe 2, a fixed split A3 and a fixed split B, wherein the fixed joint 1, the connecting pipe 2, the fixed split A3 and the fixed split B4 are all connected through threads, and the whole length of a sensor connector is adjusted by adjusting the screwed depth.
One end of the fixed joint 1 is provided with an external thread which is in threaded connection with a temperature measurement part arranged on the temperature measurement sensor, and the other end of the fixed joint is provided with an internal thread which is in threaded connection with the connecting pipe 2; the external thread and the internal thread are both 1/8 taper threads, and the sealing performance between parts is ensured.
One end of the connecting pipe 2 is provided with an external thread which is in threaded connection with the internal thread end of the fixed joint 1, and the other end of the connecting pipe is provided with an internal thread which is in threaded connection with the external threads of the fixed split A3 and the fixed split B; the inside of the connecting pipe 2 is a hollow structure.
The fixed split A3 and the fixed split B are hollow and stepped, and contact with the edge of a protective sleeve of the temperature sensor to restrain the axial movement of the sensor.
Determining the thread tightening depth between the fixed joint 1 and the connecting pipe 2 according to the depth of the machined hole of the part to be measured and the length of the temperature measuring sensor, and finally realizing the installation of the temperature measuring sensor; after the temperature measurement is finished, the sensor is disassembled and reused by rotating the connecting pipe 2.
