Description

Technical Field

[0001] This utility model belongs to the technical field of pneumatic measuring instruments, specifically, it relates to a portable pneumatic pressure measuring instrument. Background Technology

[0002] A pneumatic measuring instrument generally consists of two parts: the instrument body (float-type, pointer-type, or electronic pneumatic measuring instrument) and the measuring device. The same pneumatic measuring instrument body, equipped with different pneumatic measuring heads, can measure a wide variety of parameters of a workpiece, such as length, thickness, groove width, inner hole diameter, outer diameter, center distance between two holes, straightness of the axis, roundness, coaxiality, perpendicularity, and flatness. Application No. CN202322120089.2 discloses a portable pneumatic pressure measuring instrument. When removing the measuring head, simply pull the clamping component upward to release the restriction on the measuring head, which is convenient to use. After use, the measuring head can be placed directly in the placement slot under the top plate, where it is restrained by the clamping component. When measurement and calibration are required, the storage box can be pulled out from under the base plate to facilitate the retrieval of the calibration ring gauges. Although it has certain convenience, after the storage box is pulled out, all the calibration ring gauges are exposed to the external environment, which is easy to collect dust. The pneumatic pressure measuring instrument also collects dust when not in use. It is inconvenient to carry it by hand.

[0003] In view of this, this utility model is proposed. Utility Model Content
