Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, in particular to a pressure gauge with a protective device. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure. It is widely used in almost all industrial processes and scientific research fields. However, the pressure gauge must be protected during on-site use.

[0003] The existing pressure gauge protection method is often to install a protective cover to prevent the pressure gauge from being directly affected by external impact force, causing damage to the pressure gauge;

[0004] This conventional way of adding a protective cover has some minor problems in daily use. For example, when working outdoors, the pressure gauge is exposed to light for a long time, and the temperature rises, which may lead to a decrease in measurement accuracy. The protective cover is more complicated to disassemble and assemble. For this reason, we propose a pressure gauge with a protective device. Utility Model Content

The threaded holes are evenly arranged on the outer arc surface of the cover plate, and the inner arc surface of the docking groove is provided with evenly distributed threaded grooves. The threaded holes correspond to the threaded grooves located in the same direction one by one, thereby realizing the function of reinforcing the PVC shell.

[0011] Furthermore, it also includes a threaded tube section, which is arranged in the middle of the base. The interior of the threaded tube section is threadedly connected to the instrument docking threaded pipe to achieve the function of connecting the pressure gauge.

[0012] Furthermore, the sunshade protection mechanism includes a fixed shaft, a rounded corner plate and a rotating shaft. The fixed shafts are symmetrically arranged on the left and right sides of the outer arc surface of the base. The outer arc surfaces of the two fixed shafts are fixedly connected with rounded corner plates respectively. The upper sides of the two rounded corner plates are rotatably connected with a rotating shaft to realize the function of external protection.

[0013] Furthermore, the sunshade protection mechanism also includes a mounting flange, and the mounting flange is arranged at the lower end of the base to achieve the installation function.

[0014] Furthermore, the sunshade protection mechanism also includes a sunshade, and the sunshade is fixedly connected to the outer surface of the rotating shaft to achieve a sunshade function.
