Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure reducers, in particular to a quick connection device for a gas pressure reducer. Background Art

[0002] A pressure reducer is a device that reduces the high-pressure oxygen stored in an oxygen cylinder to the low-pressure oxygen required for gas welding. Because the pressure inside the cylinder is high, while the pressure required for gas welding and gas cutting is lower, a pressure reducer is needed to reduce the high-pressure gas stored in the cylinder to a low-pressure gas, ensuring that the required working pressure remains stable. In short, a pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas while maintaining a stable output pressure and flow rate.

[0003] When the pressure reducer is in use, it will be installed by docking the connecting pipe with the butt joint pipe. However, the traditional docking method is to directly align one end of the butt joint pipe with one end of the connecting pipe and install it by screwing. This installation method is prone to falling off during subsequent use, thereby affecting the normal use of the pressure reducer. Therefore, corresponding improvements need to be made to the above problems. Utility Model Content

[0009] Preferably, the left side plate is disposed inside the clamping ring groove, and the right side plate is disposed between the mounting ring and the mounting block.

[0010] Preferably, the bottom ends of the left and right plates are both arc-shaped, the curvature of the bottom end of the left plate matches the curvature of the inner wall of the clamping ring groove, and the curvature of the bottom end of the right plate matches the curvature of the outer surface of the connecting pipe.
