Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5, the utility model provides an airtight zipper, by the zipper strip 1 of two symmetries with arrange the zipper head that uses and constitute, zipper strip 1 is equipped with baseband 3 and assembles at 3 inboard sprocket 4 of baseband, zipper strip 1 still is equipped with the waterproof layer 5 that is located the surface and covers sprocket 4, waterproof layer 5 is bent towards sprocket 4 meshing one side and is formed the bending part 6, the zipper head is equipped with upper plate 7 and lower plate 8 that separate from the top and bottom and is fixed by the support bar 9 of central part, upper plate 7 is equipped with the last root 10 of control sprocket 4 upper portion, last root 10 control both sides waterproof layer 5 is crooked and the fifty percent discount each other to realize in close contact between waterproof layer 5 when both sides sprocket 4 merges crowded altogether, lower plate 8 is equipped with the lower root 11 of control sprocket 4 lower part, specifically, waterproof layer 5 is through bending in advance and forming bending part 6, makes things convenient for the zip fastener's zip fastener to close and open and draw back, certainly, when actually using, waterproof layer 5 also can adopt the flexible material that resets, and the open when opening, utilize when pulling to make the zip fastener produce the zip fastener 5 and buckle.

Waterproof layer 5 is located the top of zipper strip 1 and covers

sprocket

4, and 3 one end of baseband then can cover or do not cover, convenient processing, and can not leave the clearance, can guarantee waterproof performance, waterproof layer 5 transversely extends from the inboard edge of baseband 3 at its place, sprocket 4 is located the below of its place baseband 3, can guarantee the level and smooth pleasing to the eye on zipper strip 1 surface like this, also can avoid zipper strip 1 too thick and influence the use, perhaps zipper strip 1 also can adopt sprocket 4 to be located baseband 3 sides, the zipper structure of other common forms such as top.

Waterproof layer 5 is an elastomer, can adopt the preparation of elasticity material commonly used such as resin, plastics, makes the kink 6 of waterproof layer 5 have the trend of replying to the flat state like this, can make the kink 6 of two waterproof layers 5 can be more inseparable compress tightly together from this to also can guarantee the inseparable laminating of two bending portions 6 when this zip fastener is crooked, can effectively guarantee water-proof effects, facilitate the use.

The bending part 6 of the waterproof layer 5 towards the meshing side of the zipper teeth 4 is bent upwards or downwards, so that the flatness and the attractiveness of the upper surface of the zipper towards the outside can be ensured, and the zipper is convenient to use.

The upper root 10 and the lower root 11 face one end of the tight link of the slider at the same time, and normal pulling of the link belt 1 is ensured.

The two sides of the lower transfer plate 8 are provided with guide surfaces 12 for guiding the zipper strips 1, and as the zipper strips 1 enter, the guide surfaces 12 can guide the waterproof layer 5 on the zipper strips 1 to bend to form bending parts 6, and normal closing and pulling of the zipper strips 1 can be effectively guaranteed.

Be equipped with filling block 13 between the adjacent sprocket 4 on the zipper strip 1, when two zipper strips 1 were zipped, filling block 13 can fill up the clearance between each sprocket 4 that is full of two zipper strips 1, can further promote the water-proof effects of 4 parts of sprocket like this to can effectively improve 4 waterproof performance, in this technical scheme, filling block 13 is formed by waterproof layer 5 downwardly extending, can avoid filling block 13 to drop, helps the extension the utility model discloses a life, waterproof layer 5 and filling block 13 can be on zipper strip 1 integrated into one piece.

Compared with the prior art, this technical scheme has utilized both sides waterproof layer 5 to form behind the structure of buckling, compresses tightly each other along with zipper strip 1 meshing back and strengthens the centre space department sealed, realizes the waterproof nature behind the 4 meshing of sprocket, has improved inside gas tightness greatly, has improved holistic water-proof effects.

When the zipper tape 1 is pulled by the zipper head, the waterproof layers on the upper sides are in close contact with each other after being bent along with the meshing connection of the zipper teeth 4 on the two sides, and the waterproof layers directly cover the zipper teeth 4 to strengthen the waterproof property.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
