Description

Technical Field

[0001] The utility model relates to the field of carbon dioxide welding, in particular to a carbon dioxide centralized gas supply device for welding. Background Art

[0002] Carbon dioxide welding, also known as carbon dioxide gas shielded welding, is a welding method that uses carbon dioxide gas as a shielding gas.

[0003] After searching, the application number is "202321906103.5", which provides a carbon dioxide centralized gas supply equipment for steel cage welding. The mounting plate is fixed to the main body by bolts, and the gas cylinder is placed on the support plate. The bottom of the gas cylinder can be protected by the set rubber pad. Turn the knob to drive the threaded rod to rotate, so that the second connecting plate moves downward, and the lower pressure plate moves downward, so that the positioning groove is sleeved on the outside of the gas cylinder to fix the gas cylinder. The anti-slip pad is set to make the lower pressure plate fix the gas cylinder more firmly. While the lower pressure plate moves downward, the first connecting plate slides on the limiting shaft, so that the movement of the lower pressure plate is more stable and the overall structure is more stable. After the gas cylinder is fixed, the top of the gas cylinder pushes the cover plate to move upward, driving the sliding shaft to move upward, and compressing the spring. Under the reaction force of the spring, the sealing ring presses against the outer wall of the gas cylinder to seal the joint of the gas cylinder to prevent leakage at the joint. At the same time, the sealing plug presses against the bottle mouth of the gas cylinder.

[0004] The above-mentioned method controls the connection between the connecting component in the lower pressure plate and the carbon dioxide tank by rotating the threaded rod, which facilitates the replacement of the carbon dioxide tank. However, when replacing the carbon dioxide tank, this structure requires the staff to extract the used carbon dioxide tank and then place a new carbon dioxide tank for connection. Due to the heavy weight of the carbon dioxide tank, the staff is slow to replace the new carbon dioxide tank, which reduces the progress of carbon dioxide welding. Utility Model Content
