Example Embodiment

[0012] Such as figure 1 with figure 2 The pressure gauge indicating device of the present invention shown has a ring-shaped body 1, and the body 1 can be made of a metal material with anti-rust and anti-corrosion properties. A pointer sliding part 2 connected to the body 1 is extended along the axial direction of the body 1, and a guide groove 3 is provided in the pointer sliding part 2. The pointer 5 on the radially inner surface of the body 1 coated with red night-use reflective paint is connected to the guide groove 3 through the threaded cap 4 on the outer side of the body 1, and the pointer 5 can be at a central angle of 90° along the guide groove 3 Sliding within the range, and fastened to the guide groove 3 by the screw cap 4. The main body 1 is provided with a connecting portion 6 which can be connected by a screw-fitted fastener 7, so that the main body 1 can be placed outside the pressure dials of various specifications and sizes.

Abstract

The invention relates to a pressure gauge indicating device. The pressure gauge indicating device is provided with an annular body and is characterized in that a pointer slide part extends along the axial direction of the body and is connected with the body, the pointer slider part is provided with a guide rail groove inside, and a pointer arranged on the radial inner side of the body is connected with the guide rail groove in a matched manner through a threaded cap on the outer side of the body. The pressure gauge indicating device is simple in structure, convenient to mount, capable of conveniently regulating and setting different indicating positons according to the needs of different occasions, good in universality, long in service life and capable of avoiding problems such as indicating vagueness or failure caused by natural causes.

Description

technical field [0001] The invention relates to a pressure gauge indicating device. Background technique [0002] The pressure gauge is a pressure indicating device commonly used in many industrial production environments, which plays a very important role in the safety of production. According to the regulations of some industries, an indicator line indicating the working pressure or warning pressure should be drawn on the dial of the pressure gauge, and the indicator line can usually only be painted with colored (such as red) paint or colored pens, or on the pressure gauge dial Paste red line scale stickers instead of spray painting. However, because the pressure gauge is usually made of glass, its adhesion to paint and ink is poor, and the pressure gauge is mostly used in the open air, and the paint, ink or paper stickers are easy to fall off after being exposed to the sun and rain, making the effective time of the indication Short, making the indicator line difficult t...
