Description

Bow-shaped frame of diaphragm type pressure gauge

Technical Field

The utility model relates to the field of stamping production, in particular to a bow-shaped frame of a diaphragm pressure gauge.

Background

The pressure gauge is a meter which takes an elastic element as a sensitive element and measures and indicates the pressure higher than the ambient pressure, is very commonly applied and almost extends to all the fields of industrial processes and scientific researches.

The diaphragm pressure gauge usually adopts a bow-shaped frame component, and the structure is a supporting frame of an internal structure. The bow-shaped frame in the pressure gauge in the prior art is formed by multiple times of die pressing and punched for multiple times, and the side debugging window is designed in a four-hole uniform distribution mode. The bow-shaped frame is punched, the production procedures are multiple, the range of the debugging window extending into the tool is narrow, the installation and debugging of the pressure gauge are not facilitated, the production efficiency is low, the processing cost is high, and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a bow-shaped frame of a diaphragm pressure gauge.

In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a bow-shaped frame of diaphragm pressure gauge, includes bottom, first window, rib, second window and upper portion, and arranges in proper order, first window and second window set up in a staggered way, and the both sides of first window are provided with first fulcrum, third fulcrum respectively, the middle part of first window is provided with the second fulcrum, first fulcrum and third fulcrum are used for connecting bottom and rib, the second fulcrum is used for connecting rib and upper portion, the second fulcrum is located the perpendicular bisector between first fulcrum and the third fulcrum.

As a further description of the above technical solution:

the upper end face of the upper portion is provided with an opening, one side of the opening is provided with two through holes, and the number of the through holes is two.

The utility model has the following beneficial effects: set up the pre-punched breach, the stamping forming back forms the adjustment window, compares in the processing of traditional adjustment window, not only can reduce the consumption of material, still is favorable to reducing the step of low production process, has reduced manufacturing cost.
