DETAILED DESCRIPTION
[0019] The present invention will be described in detail below with reference to the accompanying drawings.
[0020] An integrated vacuum box device for air bag sampling, such as Figure 1-Figure 3As shown, it includes a support frame 1, a vacuum pump 2, a vacuum box 3, an observation window 4, a sealing cover 5, a suction port 6, a suction pipe 7, a connecting nut 8 and a connecting assembly. The lower part of the support frame 1 is connected to the vacuum pump 2, and the vacuum pump 2 is provided with a plurality of knobs for easy control. The upper side of the support frame 1 is connected to the vacuum box 3, and the front side of the vacuum box 3 is provided with an observation window 4. The upper side of the vacuum box 3 is rotatably connected to the sealing cover 5, and the upper left front side of the sealing cover 5 is connected to the suction port 6. The vacuum pump 2 is connected to the suction pipe 7, and the upper part of the suction pipe 7 is connected to the connecting nut 8. The connecting nut 8 is provided with a handle for easy rotation. The connecting nut 8 is threadedly connected to the suction port 6, and a connecting assembly is provided on the vacuum box 3.
[0021] like Figure 4 and Figure 5 As shown, the connecting assembly includes an external connecting port 9, a fixed block 10, a motor 11, a control valve 12, a connecting block 13, an internal connecting port 14 and a rotating block 15. The left and right parts of the vacuum box 3 are connected to the external connecting port 9, and the left and right sides of the upper part of the vacuum box 3 are connected to the fixed blocks 10. The fixed blocks 10 are connected to the motor 11, and the output shaft of the motor 11 is connected to the control valve 12. The control valve 12 is rotatably connected to the external connecting port 9. The external connecting ports 9 are connected to the connecting blocks 13 on the side where they are close to each other, and the rotating blocks 15 are clamped on the connecting blocks 13. The ends of the external connecting ports 9 that are away from each other are also rotatably connected to the rotating blocks 15. The rotating blocks 15 clamped with the connecting blocks 13 are rotatably connected to the internal connecting port 14. The internal connecting ports 14 are in contact with adjacent external connecting ports 9, and the rotating blocks 15 are provided with positioning protrusions for easy quick connection.
[0022] When using the present invention, first place the support frame 1 in the gas sampling area, then rotate to open the sealing cover 5, place the gas bag for sampling inside the vacuum box 3, and then connect the gas bag to the internal connecting port 14 through the sampling pipe. After the connection is completed, rotate the sealing cover 5 to close the vacuum box 3, and then tighten the connecting nut 8 on the suction port 6 and start the vacuum pump 2, and extract the inside of the vacuum box 3 to a vacuum state through the suction pipe 7.

After the sampling air bag is collected, the motor 11 can be started, the control valve 12 is turned to close, and the sealing cover 5 is turned to open to take out the sampling air bag after sampling is completed, thereby completing the sampling process, thereby playing the role of an integrated air bag sampling vacuum box 3 with an integrated vacuum pump 2 and a connecting pipeline, simplifying the operation process of air bag sampling, and improving the efficiency and accuracy of air bag sampling. A plurality of internal connecting ports 14 are provided in the vacuum box 3, which can collect air through multiple air bags at the same time. By rotating the rotating block 15, the rotating block 15 can be separated from the connecting block 13, and the internal connecting port 14 can be quickly removed or installed from the external connecting port 9, so that the internal connecting port 14 can be quickly installed and adjusted according to the number of sampling air bags to meet different sampling needs.
