[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following will describe this in conjunction with the preferred embodiments of the device of the present utility model.

[0025] Please refer to Figures 1-5 As shown, the gas pipeline that is easy to disassemble includes a first gas pipeline 2 and a second gas pipeline 3, and the first gas pipeline 2 and the second gas pipeline 3 are docked through a connection mechanism 1;

[0026] Among them, the connection mechanism 1 includes a connecting pipe 101 arranged between the first gas pipeline 2 and the second gas pipeline 3. An internal thread 102 is arranged along the pipe body direction inside the connecting pipe 101. The internal thread 102 cooperates with the external threads 4 of the first gas pipeline 2 and the second gas pipeline 3, and the two are tightly connected by rotation. A connecting sleeve 105 is sleeved outside the connecting pipe 101. The connecting sleeve 105 is used to fix and support the connecting pipe 101, and at the same time provides a platform for installing the connecting support plate 106. Connecting support plates 106 are symmetrically arranged on both sides of the outside of the connecting sleeve 105 with respect to the axis. Installation holes 107 are transversely provided in the two connecting support plates 106 corresponding to each other. The installation holes 107 are used to pass through bolts 108 and install nuts 109 to realize the fastening of the connection mechanism 1. A bolt 108 is fixedly installed in one of the installation holes 107, and the other end of the bolt 108 extends to the other installation hole 107 and is sleeved with a nut 109. The bolt 108 passes through the installation hole 107 and tightens the nut 109 to fix the connecting support plate 106 and the connecting sleeve 105 together, thereby ensuring the stability of the connection mechanism 1.

[0027] Furthermore, external threads 4 that cooperate with the internal thread 102 are provided on the outside of the opposite sides of the first gas pipeline 2 and the second gas pipeline 3.

[0028] Furthermore, limit pads 103 that are adapted to the first gas pipeline 3 and the second gas pipeline 2 are provided at both ends of the connecting pipe 101. The limit pads 103 prevent the offset when the gas pipeline is inserted.

[0029] Furthermore, a sealing ring 104 is sleeved outside the connection part of the first gas pipeline 2 and the second gas pipeline 3 inside the connecting pipe 101. The sealing ring 104 enhances the sealing performance of the connection part and prevents gas leakage.

[0030] Furthermore, there are two groups of bolts 108 arranged horizontally.

[0031] Specifically, the internal thread 102 inside the connecting pipe 101 rotates with the external thread 4 of the first gas pipeline 2 and the second gas pipeline 3 to form a preliminary tightening; the connecting sleeve 105 wraps the connecting pipe 101 and provides support, and the bolts 108 and nuts 109 on the connecting support plate 106 fix the connecting sleeve 105 through the tightening action, thereby enhancing the stability of the connecting mechanism 1; in addition, the sealing ring 104 is ring-shaped at the connection to ensure that the gas does not leak. The entire connecting mechanism 1 achieves efficient and stable pipeline connection through the close cooperation of these components.

[0032] When disassembling the gas pipeline, first loosen the bolts 108 on the connecting support plate 106 one by one by turning the knob nut 109 until they are completely loosened, release the fixing of the connecting sleeve 105 on the connecting pipe 101, and then hold the connecting pipe 101, rotate the first gas pipeline 2 and the second gas pipeline 3 in turn, so that the first gas pipeline 2 and the second gas pipeline 3 are separated from the connecting pipe 101. After separation, check whether the first gas pipeline 2, the second gas pipeline 3, the connecting pipe 101, the sealing ring 104 and other components are damaged or worn, and replace or repair them if necessary.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
