The gap formed between the tube 22 and the second cover 23 is connected to avoid leakage of gas.
第一套蓋13可螺固在第一管身21的頂端，第二套蓋23可螺固在第二管身21的頂端；更甚者，至少一第一螺栓B1(本創作以兩個相對設置的第一螺栓為圖例進行說明，但並不以此為限)穿經第一套蓋13的一第一外環側而頂抵第一管身11的一外表面，使第一套蓋13固定在第一管身11外；至少一第二螺栓B2(本創作以兩個相對設置的第二螺栓為圖例進行說明，但並不以此為限)穿經第二套蓋23的一第二外環側而頂抵第二管身21的一外表面，使第二套蓋23固定在第二管身21外。The first cover 13 can be screwed on the top end of the first body 21, and the second cover 23 can be screwed on the top end of the second body 21; moreover, at least one first bolt B1 (this creation is two The first bolt is oppositely disposed, but is not limited thereto, and passes through a first outer ring side of the first cover 13 and abuts against an outer surface of the first pipe body 11 to make the first sleeve The cover 13 is fixed to the outside of the first pipe body 11; at least one second bolt B2 (this is illustrated by two oppositely disposed second bolts, but not limited thereto) is passed through the second cover 23 A second outer ring side abuts against an outer surface of the second tubular body 21 to fix the second cover 23 outside the second tubular body 21.
如第6圖所示，於使用時，第一組的瓦斯管接頭結構100(圖中左側)之第一管件1的公連接管12可與一瓦斯輸出口200螺接 連通，而第二管件2的母連接管22可與一連通管400連通；第二組的瓦斯管接頭結構100(圖中右側)之第二管件2的母連接管22與連通管400的另一端連通，而第一管件1的公連接管12可與一瓦斯輸入口300螺接連通；由於第一滾珠14及第二滾珠24的設置，使公連接管12可轉動地插設在第一管身11內以及母連接管22可轉動地插設在第二管身21內，因此，當具有瓦斯輸入口300的機台500移動時，利用可轉動的第一管件1及第二管件2以避免連通管400兩端的連接斷裂而導致瓦斯氣體外洩，造成工安危險。As shown in FIG. 6, in use, the male connecting pipe 12 of the first pipe member 1 of the first group of gas pipe joint structures 100 (left side in the drawing) can be screwed to a gas output port 200. Connected, and the female connecting pipe 22 of the second pipe member 2 can communicate with a communicating pipe 400; the female pipe connecting pipe 22 of the second pipe member 2 of the second group of the gas pipe joint structure 100 (the right side in the drawing) and the connecting pipe 400 One end is connected, and the male connecting tube 12 of the first pipe member 1 can be screwed into the gas input port 300; because the first ball 14 and the second ball 24 are disposed, the male connecting pipe 12 is rotatably inserted in the first The tubular body 11 and the female connecting pipe 22 are rotatably inserted into the second tubular body 21, so that when the machine 500 having the gas inlet 300 moves, the first tubular member 1 and the second tubular member 2 are rotated. In order to avoid the connection of the connection between the two ends of the connecting pipe 400, the gas is leaked, which causes a safety hazard.
