Digital display pressure sensor adopting steel wire to position rotating angle

Abstract

The invention relates to a digital display pressure sensor adopting a steel wire to position a rotating angle. The digital display pressure sensor comprises a display panel; an outer tube is arranged below the display panel; a side surface of the outer tube is provided with an electrical interface; an elastic body joint is arranged at the lower part of the outer tube; the upper surface of the elastic body joint is provided with a circular groove; an arc-shaped steel wire bar is arranged in the circular groove; the arc-shaped steel wire bar is located at the inner circular arc edge of the circular groove; the radius of the circular arc of the arc-shaped steel wire bar is identical to the radius of the circumferential periphery of the circular groove; and the arc-shaped steel wire bar is fixed to the bottom of the circular groove. The arc-shaped steel wire bar of the digital display pressure sensor has little possibility of falling off. The digital display pressure sensor has the advantages of long service life and flexible rotation.

Description

technical field [0001] The invention relates to a digital display pressure sensor which adopts a steel wire to locate the rotation angle. Background technique [0002] The digital display pressure sensor is a pressure detection device. It uses a high-precision pressure sensitive element as the measuring element, and uses a digital circuit to convert the physical signal induced by the pressure sensitive element into an electrical signal, and displays the measured value in real time through the digital display head. The digital display pressure sensor includes a rotating structure. Through the rotating structure, the joint can be rotated flexibly. In some narrow spaces under working conditions, the product can be installed smoothly and the display position can be easily adjusted to facilitate the observation of measurement data. [0003] The traditional digital display pressure sensor uses steel balls to locate the rotation angle, and the lower part of the outer tube is connec...

AI Technical Summary

Problems solved by technology

[0004] The positioning of the rotation angle by the steel ball has the following defects: 1. The steel ball is inconvenient to be welded and fixed, and the traction is poor. After a certain amount of rotation, the positioning steel ball may fall off, and the service life is short; 2. There is a certain distance between the two steel balls. The set screw embedded in the outer tube does not reach a certain depth value, the sensor may slip when rotating, and the rotation fixing effect will be lost. If the set screw embedded is too tight, the rotation will not be flexible
