Abstract

The utility model discloses a kind of non-regulating pointer pressure, including:Including connecting rod (1), sector gear (2), bourdon tube (3), hairspring (4), scale (5), pointer (6), it is characterised in that:Also include scale (5);Each numerical point scale of the scale (5), drives the sector gear (2) and the connecting rod (1) to cause the corner that the pointer (6) is produced consistent in the presence of measured medium pressure with the bourdon tube (3) free end.This utility model solved in the past artificial adjustment man-hour length, the problems such as precision is low, stability is poor, with operating procedure is simple, practical, high precision the features such as, substantially increase the production efficiency and economic benefit of pointer pressure.

Description

A kind of non-regulating pointer pressure
Technical field
This utility model belongs to instrument and meter manufacturing technology field, more particularly to a kind of non-regulating pressure gauge.
Background technology
In industry and scientific research field, pointer pressure is due to there is very high mechanical strength to obtain using elastic sensing element Extensive application is arrived.Pointer pressure operation principle is:When measured medium enters elastic sensing element bullet by interface unit During the inner chamber of reed pipe, elastic sensing element its free end in the presence of measured medium pressure can produce corresponding displacement, and lead to Cross gear drive enlarger and leverage is converted to corresponding corner displacement, the gauge pointer synchronous with corner displacement will The pressure of measured medium is indicated on the scale groove of registration device.As the scale of pointer pressure is using uniform quarter Degree, so manufacturing process is relative complex, especially, nonlinearity erron overproof to zero point, linearity error, the overproof equal error of amount of change Adjustment waste time and energy, need the pure craft of professional to the bourdon tube inside pressure gauge, sector gear, connecting rod, hairspring, degree The mechanical transmission components such as disk, pointer are one by one or circulation is adjusted, and adjustment time accounts for more than half of production time.
Utility model content
The purpose of this utility model is:A kind of non-regulating pointer pressure is provided, is characterized in that circular graduation is uneven, Solve in the past artificial adjustment man-hour length, the problems such as precision is low, stability is poor, with operating procedure is simple, practical, high precision The features such as, further improve the production efficiency and economic benefit of pointer pressure.
The technical solution of the utility model is:A kind of non-regulating pointer pressure includes connecting rod, sector gear, spring Pipe, hairspring, scale, pointer;Each numerical point scale of the scale, with the bourdon tube free end in measured medium pressure In the presence of drive the sector gear and connecting rod to cause the corner that the pointer is produced consistent.
This utility model is in the past artificial by using uneven but consistent with the elastic Sensitive Apparatuses scale of scale, solving Adjustment man-hour length, the problems such as precision is low, stability is poor, with operating procedure is simple, practical, high precision the features such as, significantly Improve the production efficiency and economic benefit of pointer pressure.
