Description

Technical Field

[0001] The utility model relates to the technical field of oxygen pressure reducers, in particular to an oxygen pressure reducer with a protection structure. Background Art

[0002] An oxygen pressure reducer is generally a pressure reducing device for bottled gas. When the inlet pressure and outlet flow rate change, the outlet pressure is guaranteed to remain stable. An increase in the low-pressure gauge reading may indicate potential danger and hidden dangers. Since high pressure is not required during welding and gas cutting, and the pressure stored in the cylinder is very high, there is a large gap between the two. In order to adjust the high-pressure gas in the cylinder to the low pressure during work and keep the low pressure stable during use, a gas pressure reducer is required.

[0003] According to the search, the Chinese patent document, announcement number: CN220102261U, discloses an oxygen pressure reducer with a protective structure. This solution sets a protective shell to cover the low-pressure oxygen meter and the high-pressure oxygen meter, thereby achieving the purpose of protection and preventing the low-pressure oxygen meter and the high-pressure oxygen meter from being damaged due to violent collision with foreign objects; the utility model pulls the pull block, and the pull block drives the fixed rod to disengage from the slot, so that the plug block is released from the restriction, thereby facilitating the removal of the protective shell, and the operation is simple and convenient. However, the oxygen pressure reducer with a protective structure still has defects during use. The device has low adaptability and cannot adapt to a variety of oxygen pressure reducers of different sizes. Utility Model Content
