Description

General screwing device for pressure sensor Technical Field The utility model relates to the technical field of pressure sensors, in particular to a general tightening device for a pressure sensor. Background A pressure sensor is a delicate and powerful device or apparatus whose core function is to sense and respond to a pressure signal. In particular, it is able to capture pressure variations from various environments or systems, which may be due to the pressure effects of gases, liquids or solids. Once these pressure signals are sensed, these pressure signals in non-electrical form are converted into electrical signals. The pressure sensor is screwed up by inside spare part and outside base and forms, operating pressure is great, in order to prevent its leakage, the base needs great moment of torsion to tighten, traditional screwing up mode is, through the top of spring and fixed plate to pressure sensor, constantly exert decurrent force, fix pressure sensor, it is because of the too big purpose that causes sensor fish tail or the accidental injury operating personnel of application of force to push down the sensor from the top, screw up pressure sensor's bottom through bottom screwing up mechanism afterwards, and when screwing up in the bottom, need great force, will make the top move down along with the continuous screwing up of bottom, but because the spring is easy to produce deformation when receiving the force, lead to the top to pressure sensor fixed unstable, consequently, need improve and optimize it.
