Abstract

A pressure gauge comprises an outer shell, a pressure dial plate, a movement transmission mechanism, a C-shaped bourdon tube and an outer connector. A containing cavity used for containing the pressure dial plate, the movement transmission mechanism and the C-shaped bourdon tube is formed in the outer shell, and an arc-shaped inner contact device comprises an arc-shaped outer connecting piece andan arc-shaped inner connecting piece. The end parts of the arc-shaped outer connecting piece and the arc-shaped inner connecting piece are connected with each other through an insulating elastic diaphragm, and the inner side surface of the arc-shaped outer connecting piece is provided with an arc-shaped outer contact piece which is fixed with the arc-shaped outer connecting piece and is made of aconductive material. An arc-shaped inner contact piece made of a conductive material and fixed with the arc-shaped inner connecting piece is arranged on the side surface, opposite to the direction ofthe arc-shaped outer connecting piece, of the arc-shaped inner connecting piece. When the C-shaped bourdon tube expands to a set value, the C-shaped bourdon tube and the arc-shaped outer connecting piece form abutting fit, the arc-shaped outer connecting piece drives the arc-shaped outer contact piece to incline or move so as to overcome the elastic acting force of the insulating elastic diaphragmto electrically contact the arc-shaped inner contact piece, and therefore starting and stopping of a first switch are controlled.

Description

technical field [0001] The invention relates to the field of pressure detection, in particular to a pressure gauge. Background technique [0002] A barometer is an instrument used to measure air pressure, and there are many types. When the conventional barometer is in use, the air pressure enters the diaphragm cavity through the pressure gauge joint, causing the diaphragm in the Bourdon tube to deform and displace, and then pushes the movement transmission mechanism, causing the pointer connected to the movement transmission mechanism to rotate, and then indicates Pressure value, but when the air pressure reaches the maximum pressure of the surface scale. The Bourdon tube of the conventional pressure gauge will be excessively deformed, which will cause permanent damage to the Bourdon tube, causing the pressure gauge to be scrapped and increasing the cost of use. Contents of the invention [0003] In order to solve the above problems, the invention provides a pressure gau...
