Abstract

A double rotating digital display pressure switch comprises an outer pipe, a display casing and an elastic body connector. The display casing is clamped on the upper portion of the outer pipe, the elastic body connector is clamped on the lower portion of the outer pipe, a first groove is formed in the periphery of the elastic body connector, two first steel balls are embedded in the first groove, a through hole is formed in the outer pipe, a fastener is arranged in the through hole of the outer pipe, and the tail end of the fastener stretches into the first groove and arranged between the two first steel balls. Two second steel balls are fixed on the upper portion of the outer pipe, a protruding corner is arranged on the lower portion of the display casing, and the tail end of the protruding corner on the lower portion of the display casing is arranged between the two steel balls. During use, the elastic body connector can rotate between the two first steel balls, and the display casing can rotate between two second steel balls, and a product can rotate in the 360-degree range by means of matching of the elastic body connector and the display casing and can smoothly work under occasions where working conditions are small and operation is inconvenient, convenient direction display and convenient online operation are provided, and product installation practicability is improved.

Description

technical field [0001] The invention relates to a double-rotation digital display pressure switch. Background technique [0002] The digital display pressure switch is based on high-performance electronic components and high-precision pressure-sensitive components as measuring components. It uses digital circuits to convert the physical signals induced by the pressure-sensitive components into electrical signals. It integrates pressure measurement, display and control. Intelligent high-precision pressure control equipment. The digital display pressure switch can provide continuous pressure monitoring, and can easily set the switch point and hysteresis point without booster equipment. It has the advantages of high accuracy, small size, easy operation and use, and is widely used in chemical industry and machinery. In the pressure control and automatic process control system of hydraulic, electric and other systems. [0003] At present, the domestic transportation method for ...
