AI Technical Summary

Technical Problem

In existing piezoelectric sensor verification and calibration devices, the connection between the socket and the power plug is prone to wear, which can cause the socket and plug to loosen during installation, affecting the normal use of the device.

Method used

A device for the verification and calibration of a piezoelectric sensor was designed. The stability of the plug is improved by combining an operating block, a transmission screw, a threaded sleeve block, and a limiting block. The plug can move along the axis of the operating block and be inserted into or pulled out of the socket. The stability of the plug and the socket is increased by the cooperation of the threaded rod and the limiting block.

Benefits of technology

It effectively prevents the plug and socket from loosening during installation, ensuring the normal use of the verification and calibration device. The overall structure is ingeniously designed and suitable for industrial promotion.

Abstract

The application discloses a kind of verification and calibration device and method of piezoelectric sensor, the device includes verification calibration body, operating block and plug, operating block is placed on verification calibration body, and insertion hole is provided on verification calibration body, plug can move along the axis direction of operating block, so as to be inserted into insertion hole or pulled out from insertion hole.The hollow knob is twisted after the threaded rod is placed in the corresponding assembly hole, the threaded sleeve is rotated on the rotating groove, and finally the threaded sleeve is rotated and moved on the threaded rod, so that the threaded sleeve and the limiting block clamp the assembly block, increase the stability of the threaded rod on the assembly block, the transmission screw is rotated in the threaded sleeve block by twisting the operating knob, and finally the limiting block drives the threaded rod to move to adjust the height of the plug, the insertion hole is clamped by the plug, so that the verification calibration body verifies and calibrates piezoelectric sensor, the stability of the plug is high, and the installation of the plug and the insertion hole can avoid loosening.
