AI Technical Summary
Existing pressure measurement and calibration devices require the pressure gauges being tested to be screwed on during use, which is cumbersome, has low installation and disassembly efficiency, and affects overall work efficiency.
The pressure gauge is quickly installed and sealed by a detection mechanism and a pressure relief mechanism. The sealing plate and sealing compression spring enable the installation of the pressure gauge. The mounting hinge rod is locked in place by the connecting torsion spring. The pressure relief knob and pressure relief hole work together to achieve rapid pressure relief, simplifying the operation process.
It enables rapid installation and testing of pressure gauges, reduces labor intensity, improves work efficiency, and has a good pressure relief function. The overall structure is reasonably designed, easy to operate, and improves testing efficiency.
