[0002] Pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is widely used in almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, etc. 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 convenient production.

The beneficial effects of the utility model are as follows: the first protective block and the second protective block cooperate with each other to protect the surface of the pressure gauge body, the first injection port is arranged to facilitate the injection of antifreeze liquid into the inner cavity of the first protective block, and the observation window is arranged to facilitate the observation of the antifreeze liquid reserve in the inner cavity of the first protective block, which solves the problem that most of the current pressure gauge antifreeze devices immerse the pressure gauge as a whole in antifreeze liquid, making it inconvenient to observe the gauge value of the pressure gauge, and at the same time, it is inconvenient to replace and disassemble the antifreeze device;

[0004] During use, affected by temperature changes, the surface of the pressure gauge is prone to fog, making it inconvenient to view. In addition, as the use time increases, the pressure surface is prone to accumulate dust and needs to be wiped to avoid inaccurate data. For this reason, we propose an antifreeze pressure gauge structure to solve the above problems. Utility Model Content
