[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Large packaging cover bags are generally used to package large items. After packaging, the air in the packaging bag needs to be extracted to form a vacuum state in the packaging bag, reducing the volume of the packaging bag and facilitating the transportation of the packaging bag.

[0003] The existing large packaging cover bag with a self-exhaust device is provided with a detachable vacuum pump. When in use, the vacuum pump can be used to extract the air inside the packaging cover bag to form a vacuum in the packaging cover bag. However, the vacuum pump needs to be removed after the vacuum is completed. Since the vacuum pump is connected to the connecting pipe on the packaging cover bag through a flange, the disassembly and assembly method is relatively cumbersome. It is necessary to turn multiple bolts to firmly connect the flange and the connecting pipe. In addition, the disassembly and assembly steps are relatively large and take a long time, thereby reducing the disassembly and assembly efficiency of the vacuum pump. Utility Model Content
