Description

Technical Field

[0001] The utility model relates to the technical field of an oxygen welding machine, in particular to an air supply structure of an OTC oxygen welding machine. Background Art

[0002] The oxygen welding machine is an arc welding machine that uses carbon dioxide gas as a shielding gas. This welding method is widely used in the welding of metal materials, such as steel, stainless steel, etc. The oxygen welding machine uses carbon dioxide gas as a shielding gas, which can effectively protect the welding area from being polluted by oxygen and moisture in the air, thereby improving the rust resistance of the weld, improving the welding quality and efficiency, and reducing the welding cost. Therefore, it has been widely used and recognized in the welding applications of various metal materials. However, the gas supply structure of the existing oxygen welding machine will be bumped during transportation. The gas supply structure of the oxygen welding machine has no buffer device. During the transportation bumps, the carbon dioxide gas tank is prone to collision and leakage, causing the gas supply structure of the oxygen welding machine to leak during use. Therefore, those skilled in the art provide a gas supply structure of an OTC oxygen welding machine to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide a gas supply structure for an OTC oxygen welding machine to solve the problems raised in the above background technology.

[0006] Preferably, a buffer spring fixing block is provided on the inner side of the buffer base, a buffer spring is provided on the outer end of the buffer spring fixing block, a buffer block is provided on the outer end of the buffer spring, buffer rods are provided at the lower end of the carbon dioxide gas cylinder placement base and positions corresponding to the buffer rod grooves, a carbon dioxide gas cylinder is provided at the upper end of the carbon dioxide gas cylinder placement base, and a fixing ring is provided between the outer ends of the carbon dioxide gas cylinder near the upper and lower sides and positions corresponding to the carbon dioxide gas cylinder fixing bracket.

[0007] Preferably, a carbon dioxide gas cylinder outlet pipe is provided at the upper end of the carbon dioxide gas cylinder, a sealing rubber ring is provided at the upper end of the carbon dioxide gas cylinder outlet pipe, a carbon dioxide gas pipe is provided at the upper end of the sealing rubber ring, the carbon dioxide gas cylinder outlet pipe and the left and right ends of the carbon dioxide gas pipe are provided with fixing blocks, the inner ends of the fixing blocks and the sealing rubber ring are provided with bolt grooves near the left and right sides, the inner ends of the bolt grooves are provided with bolts, and an air pressure measuring device is provided on the upper side of the inner end of the carbon dioxide gas cylinder fixing bracket.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. During the transportation of the gas supply structure of the carbon dioxide welding machine, the carbon dioxide cylinder is bumpy, and the carbon dioxide cylinder drives the carbon dioxide cylinder placement base at the lower end to vibrate. The damping rod and spring at the lower end of the carbon dioxide cylinder placement base buffer the carbon dioxide cylinder placement base, and the carbon dioxide cylinder placement base buffers the carbon dioxide cylinder. When the buffer rod at the lower end of the carbon dioxide cylinder placement base is vibrated, the buffer rod moves toward the buffer rod groove, the buffer block buffers the buffer rod, and the buffer spring buffers the buffer block, so that the carbon dioxide cylinder is buffered during the bumpy transportation. The buffer device reduces the collision of the gas tank during transportation, which can effectively reduce the risk of gas leakage, prevent the gas tank from being subjected to severe vibration or collision, help maintain the sealing of the gas tank, reduce the possibility of gas leakage, improve the safety of the transportation process, and avoid accidents caused by gas leakage.

[0010] 2. Place the carbon dioxide gas cylinder into the base at the inner end of the carbon dioxide gas cylinder fixing bracket. The fixing ring fixes the carbon dioxide gas cylinder left and right so that the carbon dioxide gas cylinder can move up and down but cannot move left and right. A sealing rubber ring is provided between the carbon dioxide gas cylinder outlet pipe at the upper end of the carbon dioxide gas cylinder and the carbon dioxide gas pipe. The sealing rubber ring can effectively seal the connection between the carbon dioxide gas cylinder outlet pipe and the gas pipe to prevent gas leakage, which ensures that the gas will not be wasted or cause danger due to leakage during the supply process. The carbon dioxide gas pipe and the carbon dioxide gas cylinder outlet pipe are fixed tightly through the bolt groove. The air pressure measuring device can monitor the change of air pressure in real time. When carbon dioxide leaks, the air pressure increases. The air pressure measuring device detects the increase in air pressure and the air pressure measuring device gives an alarm. BRIEF DESCRIPTION OF THE DRAWINGS
