Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 to 3, a leakproof and open-proof zipper fitting comprises a first air duct 1 and a second air duct 2. One end of the first air pipe 1 is provided with a first connecting cloth 3, and one side of the first connecting cloth 3, which is far away from the first air pipe 1, is fixedly provided with a first sprocket 4. One end of the second air pipe 2 is provided with a second connecting cloth 5, and one side of the second connecting cloth 5 far away from the second air pipe 2 is fixedly provided with a second sprocket 6. After the first zipper teeth 4 and the second zipper teeth 6 are meshed and fixed, the first air pipe 1 and the second air pipe 2 can be fixed.

One end of the second sprocket 6 is fixedly provided with a base 8, one side of the base 8 is provided with a socket, one end of the first sprocket 4 is fixedly provided with a cutting 9, and the cutting 9 is matched with the socket. The second zipper teeth 6 are provided with a pull head 7, and the pull head 7 is in sliding fit with the first zipper teeth 4. The insert bar 9 is inserted into the inserting hole of the base 8 through the slider 7, and then the slider 7 is pulled, so that the slider 7 can engage the first zipper teeth 4 with the second zipper teeth 6, and the first zipper teeth 4 and the second zipper teeth 6 are fixed.

And one sides of the connecting cloth I3 and the connecting cloth II 5 are fixedly provided with leakage-proof cloth 14.
