[0020] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail with reference to the drawings.
[0021] Please refer to Figures 1-4 A multifunctional anti-explosion sampling device for gas collection, comprising an air inlet cover 1 and a collection air bag 4, one end of the air inlet cover 1 is connected with a connecting pipe 2, the side of the connecting pipe 2 away from the air inlet cover 1 abuts against a second rotary cover 6, the collection air bag 4 is connected to one side of the second rotary cover 6, and the gas in the air inlet cover 1 is collected in the collection air bag 4 through the connecting pipe 2 and the second rotary cover 6, and the collection air bag 4 is connected at both ends with an air inlet pipe 7 and a first rotary cover 5 for gas storage and release.
[0022] Please refer to Figure 3 、 4 , the second rotating cover 6 is fixedly connected with a limiting block 8 near one end of the connecting pipe 2, the limiting block 8 penetrates through the connecting pipe 2, and the second rotating cover 6 is rotated on the connecting pipe 2 through the limiting block 8 to make the gas enter, the second rotating cover 6 can be connected to the connecting pipe 2 through the limiting block 8 connected to the second rotating cover 6, and the connecting pipe 2 can be opened and closed by rotating the second rotating cover 6.
[0023] The gas collecting bag 4 is fixedly connected with an air inlet pipe 7 near one end of the connecting pipe 2, the air inlet pipe 7 is sleeved on the outer wall of the second rotating cover 6, the outer wall of the air inlet pipe 7 is sleeved with the restraint chain 3, and the gas collecting bag 4 and the air inlet pipe 7 are both elastic. In use, the air inlet pipe 7 can be sleeved on the second rotating cover 6, and the gas can be collected in the gas collecting bag 4.
[0024] The connecting pipe 2 is fixedly connected with the first rotating cover 5 rotatably connected to one end of the connecting pipe 2, and the connecting pipe 2 and the first rotating cover 5 connected to one end of the gas collecting bag 4 can be used to store and release the gas in the gas collecting bag 4.
