[0002] The glass micro-fusion pressure sensor is a high-precision pressure measurement device based on MEMS (Micro-Electro-Mechanical Systems) technology. It fuses a silicon strain gauge with a stainless steel diaphragm using a high-temperature sintering process, forming a leak-free integral structure. Its core features include high stability, shock resistance, and wide measurement range coverage, making it suitable for high-pressure, complex environment monitoring needs in fields such as automotive, industrial control, and new energy.

[0003] For example, Chinese Patent Application No. 201822232338.6 discloses a glass micro-melting pressure sensor, comprising: a substrate including a top and an opposite bottom, and a side portion located between the top and bottom; a pressure cavity having an inlet penetrating the bottom surface of the substrate; a deformation diaphragm located on the side portion of the substrate, the deformation diaphragm including an inner surface and an outer surface opposite to the inner surface, the inner surface of the deformation diaphragm coinciding with a portion of the side cavity wall of the pressure cavity; and a strain gauge located on the outer surface of the deformation diaphragm. The glass micro-melting pressure sensor of this invention has a small deformation diaphragm overload and reduced fatigue, thus enhancing the stability and extending the lifespan of the glass micro-melting pressure sensor.

[0004] However, the aforementioned glass micro-fusion pressure sensor has a relatively limited installation method and cannot flexibly adapt to the needs of different industrial scenarios.

[0025] In one embodiment of this utility model, the connecting protective sleeve 4 includes a first protective sleeve 41, a reinforcing mounting block 42 fixed to the outer side of the first protective sleeve 41, a second protective sleeve 43 hinged to the outer side of the first protective sleeve 41, a first metal pad 44 fixed to the outer side of the first protective sleeve 41, a second metal pad 45 fixed to the outer side of the second protective sleeve 43, a first semi-threaded post 46 installed on the outer side of the first metal pad 44, a second semi-threaded post 47 fixed to the outer side of the second metal pad 45, the reinforcing mounting block 42 and the glass micro-melting pressure sensor body 1 are fixedly connected, the corresponding surface of the first metal pad 44 is in contact with the second metal pad 45, the outer sides of the first semi-threaded post 46 and the second semi-threaded post 47 are threadedly connected to a reinforcing threaded sleeve 48, and the inner walls of the first protective sleeve 41 and the second protective sleeve 43 are both fixed with reinforcing sleeves 49.

[0026] The working principle of this utility model is as follows: This device is equipped with an installation mechanism 5. When installing the glass micro-melting pressure sensor body 1, the threaded connection port 2 can be used for direct threaded connection, reducing the risk of leakage. At the same time, the threaded connection port 2 can be fitted to the outside of the corresponding connection part. Then, the installation threaded post 51 is used to penetrate the positioning installation sleeve 3, so that the bottom surface of the metal positioning sleeve 52 is fitted to the top of the positioning installation sleeve 3.
