[0003] However, when existing high-temperature resistant sensors are installed in a housing, glue is often used to glue the sensor and the housing together. The bonding point will be exposed to dust and impurities in the air, which will reduce the glue adhesion. A long-term dry and high-temperature environment will also reduce the glue adhesion, causing separation between the sensor and the housing, reducing the protection of the internal parts of the sensor.

When the sliding block slides to the bottom of the movable block, the fixed rod is pulled to slide upward, and the rectangular section at the top of the sliding block contacts the conical section at the bottom of the movable block to drive the movable block to slide toward the end away from the insertion rod, thereby releasing the restriction of the movable block on the insertion rod, improving the convenience of disassembly between the sensor body and the shell, and increasing the efficiency of disassembly and maintenance of the sensor body.

[0010] Preferably, four groups of the fixing components are provided, which can improve the stability between the sensor body and the housing.

When the movable block 47 slides, it will also drive the sliding shaft 46 to slide in the sliding direction of the movable block 47 inside the fixed shaft 45, so that when the top block 43 slides to the bottom of the movable block 47, the top block 43 does not resist the movable block 47, thereby driving the sliding shaft 46 and the movable block 47 to reset under the action of the fixed spring 48, and driving the top block 43 to be clamped on the surface of the plug rod 42 for fixation, and the fixed component 4 includes: a fixed rod 41, an plug rod 42, a top block 43, a fixed block 44, a fixed shaft 45, a sliding shaft 46, a movable block 47, and a fixed spring 48.

[0025] The release member 49 includes: a sliding block 491, which is slidably connected to the surface of the insertion rod 42, and a movable spring 492 is fixedly installed on the top of the sliding block 491, and the movable spring 492 is fixedly installed at the bottom of the fixed rod 41. When the sliding block 491 slides to the bottom of the movable block 47, the fixed rod 41 is pulled to slide upward, and the rectangular section at the top of the sliding block 491 contacts the bottom conical section of the movable block 47 to drive the movable block 47 to slide toward the end away from the insertion rod 42, thereby releasing the restriction of the movable block 47 on the insertion rod 42, improving the convenience of disassembly between the sensor body 1 and the shell 2, and increasing the efficiency of disassembly and maintenance of the sensor body 1. Four groups are provided. A groove 440 is provided on the top of the fixed block 44, which can drive the top block 43 to pass through the fixed block 44. A hole 441 is provided on the bottom of the fixed block 44, which can drive the top block 43 to pass through the bottom of the fixed block 44. The cross section of the top block 43 is semicircular, and the circular cross section of the top block 43 can be used to abut the conical cross section of the movable block 47 to drive the movable block 47 to slide. The cross section of the movable block 47 is conical, and the circular cross section of the top block 43 and the rectangular cross section of the sliding block 491 can be used to abut the conical cross section of the movable block 47.

[0026] The sensor uses the relationship between the physical quantity and the response characteristics of the sensor for measurement. The sensor can be an electronic device, a photoelectric device, an acoustic-electric device, a magnetoelectric device, etc. Generally speaking, the sensor is composed of a sensing element and a signal conversion circuit. The sensing element is the core part of the sensor, which can sense the physical quantity to be measured. When the physical quantity to be measured acts on the sensing element, the sensing element will produce a corresponding physical response, such as current, voltage, resistance, inductance, capacitance, light intensity, etc. The signal conversion circuit will convert the physical response generated by the sensing element into a usable electrical signal or digital signal, and the high temperature resistant film 3 adhered to the surface of the shell 2 fixed to the sensor body 1 can make the sensor resistant to high temperatures. When the sensor body 1 and the shell 2 are fixed, the shell 2 can be slid downward on the top of the sensor body 1. When the shell 2 slides downward, it will drive the fixing rod 41 to slide downward. When the fixing rod 41 slides downward, it will drive the insertion rod 42 to slide downward. When the insertion rod 42 slides to the inside of the fixed block 44, the bottom of the insertion rod 42 The top block 43 will use the circular section at its bottom to contact the conical section of the movable block 47 inside the fixed block 44, and drive the movable block 47 to slide toward the surface away from the insertion rod 42. When the movable block 47 slides, it will also drive the sliding shaft 46 to slide inside the fixed shaft 45 in the same sliding direction of the movable block 47. Therefore, when the top block 43 slides to the bottom of the movable block 47, the top block 43 does not contact the movable block 47, thereby driving the sliding shaft 46 and the movable block 47 to reset under the action of the fixed spring 48, and driving the top block 43 to be clamped on the surface of the insertion rod 42 for fixation, thereby improving the installation convenience and fixing effect between the sensor body 1 and the shell 2, and increasing the protection of the internal parts of the sensor body 1.

[0027] When the shell 2 and the sensor body 1 are released from fixation, the shell 2 can be pressed again to slide downward on the surface of the sensor body 1. When the shell 2 slides downward, the sliding block 491 on the surface of the insertion rod 42 will be driven to slide downward. When the sliding block 491 slides downward, the rectangular section at the bottom of the sliding block 491 will contact the top conical section of the movable block 47, and drive the movable block 47 and the sliding shaft 46 to slide toward the surface away from the insertion rod 42 again. When the sliding block 491 slides to the bottom of the movable block 47, the fixed rod 41 is pulled to slide upward, and the rectangular section at the top of the sliding block 491 contacts the bottom conical section of the movable block 47, driving the movable block 47 to slide toward the end away from the insertion rod 42, thereby releasing the restriction of the movable block 47 on the insertion rod 42, improving the convenience of disassembly between the sensor body 1 and the shell 2, and increasing the efficiency of disassembly and maintenance of the sensor body 1.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
