Described left sprocket is connected with right sprocket engagement fit, described left sprocket is made up of left chain surface standing part and left chain inner card certain portions, right sprocket is made up of right chain surface standing part and right chain inner card certain portions, the groove of described left chain inner card certain portions is connected with a joggle with the head first that engages of right chain inner card certain portions, and the engagement head second of left chain inner card certain portions is connected with the engagement of right chain inner card certain portions.
All rectangular shapes of the cross section of described Zola's chain core and right slide fastener core.
Described sealing strip first and Zola's chain core are connected as a single entity, and sealing strip second and right slide fastener core are connected as a single entity.
Described left sprocket mouth, all rectangular shapes of right sprocket mouth.
That the Breadth Maximum L of described inner card certain portions engagement head is greater than sprocket mouth length H is 0.2-0.8mm.
The optimum value that the Breadth Maximum L of described inner card certain portions engagement head is greater than sprocket mouth length H is 0.5mm.
Compared with prior art, the beneficial effects of the utility model are:
1. sprocket of the present utility model is detachable, in the time that sprocket damages, directly changes, and without scrapping whole piece slide fastener, has greatly saved resource;
2. the utility model adopts the sealing means that sealing strip combines, and good seal performance, has anti-watertight airway dysfunction, and cost performance is high;
3. the utility model is simple in structure, low cost of manufacture;
4. the utility model application is wide, and external packing that need to anti-watertight gas all can be used.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Detachable-type sealed slide fastener, comprises left zipper strip 1, right zipper strip 2;
Described left zipper strip 1 is provided with Zola's chain core 13, and described Zola's chain core 13 is evenly provided with the left sprocket 4 that left sprocket mouth 3 is listed as and is embedded in left sprocket mouth 3 and is listed as, and the outward flange of described left zipper strip 1 is provided with sealing strip first 14;
Described right zipper strip 2 is provided with right slide fastener core 15, and described right slide fastener core 15 is evenly provided with the right sprocket 6 that right sprocket mouth 5 is listed as and is embedded in right sprocket mouth 5 and is listed as, and the outward flange of described right zipper strip 2 is provided with sealing strip second 16;
Described left sprocket 4 is connected with right sprocket 6 engagement fit, described left sprocket 4 is made up of left chain surface standing part 7 and left chain inner card certain portions 8, right sprocket 6 is made up of right chain surface standing part 9 and right chain inner card certain portions 10, the groove of described left chain inner card certain portions 8 is connected with a joggle with the head first 11 that engages of right chain inner card certain portions 10, and the engagement head second 12 of left chain inner card certain portions 8 is connected with the engagement of right chain inner card certain portions 10.
