Description

Technical Field

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

[0002] Pressure gauges are instruments that use elastic elements as sensitive elements to measure and indicate pressures higher than the ambient pressure. They are widely used in almost all industrial processes and scientific research fields. They can be found everywhere in the fields of thermal pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and easy production.

[0003] When the existing pressure gauge is in use, the main body usually does not have a protective structure, which causes the glass on the surface of the dial to shatter after an accidental collision, thereby damaging the pressure gauge dial and pointer, resulting in the entire pressure gauge being unable to be used normally. For this reason, we propose a pressure gauge with a protective device. Utility Model Content
