However, in practical application, the problem of leakage still easily occurs between the guide post part of the slider movement and the sealing strip, and it is difficult to satisfy the airtight requirement of diving zipper in high pressure environment, and through analysis, the thickness dimension of the two sealing strips when separated from each other is slightly larger than the thickness dimension of the two sealing strips when in close contact (due to different contact deformation), so that the sealing strip in the slider has a height difference, and particularly, the middle joint part where the sealing strip is separated from the sealing strip is prone to being separated, so that the leakage problem is easily caused at the position.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of background art, the utility model provides a draw zipper head and a waterproof airtight zip fastener solves current airtight zip fastener and has the problem of leaking.
The utility model discloses the technical scheme who adopts: a zipper puller comprises an upper wing plate, a lower wing plate, a machine core and a pulling piece, wherein the upper wing plate and the lower wing plate are arranged in parallel up and down and are connected through the machine core; the method is characterized in that: the machine core comprises a guide pillar and a sealing pillar which are of an integrated structure, wherein a sealing boss is arranged on the lower wing plate, and the sealing boss is arranged on two sides of the guide pillar and used for extruding the sealing strip.
The cross section of the guide post is triangular, and the sealing bosses correspondingly form a V shape.
The sealing boss has an extension extending to a rearward end.
The whole width of the sealing boss is larger than that of the machine core.
The two side edges of the sealing boss keep a spacing distance with the side wing plates, and the rear end of the sealing boss keeps a spacing distance with the rear end of the lower wing plate.
The pull tab 6 is provided on the upper flap 1.
The utility model provides an airtight waterproof zip fastener, includes zipper strip and foretell zipper head, the zipper strip is equipped with two to the correspondence is provided with the sprocket, two mutual inseparable alternate arrangement behind the sprocket meshing, still be provided with sealing coating and sealing strip on the zipper strip, two sealing strips can be closely laminated after the sprocket meshing and seal.
The utility model has the advantages that: after the zipper is pulled, the sealing boss can extrude the sealing strip, so that the height difference is eliminated, the sealing effect of the sealing strip is further ensured, and a better airtight and leakproof effect is achieved.

Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-6, an airtight waterproof zipper comprises a zipper strip 7 and zipper sliders, wherein the zipper strip 7 is provided with two zipper teeth 8, two zipper teeth are arranged in an alternate and mutually-tight manner after being meshed, the zipper strip 7 is further provided with a sealing coating and a sealing strip 9, the two sealing strips 9 can be tightly attached and sealed after the zipper teeth 8 are meshed, the front end and the rear end of the zipper strip 7 are respectively provided with a front fastener 10 and a rear fastener 11, and the rear end of the front fastener 10 is provided with a sealing groove which is in a U-shaped shape.
The zipper puller comprises an upper wing plate 1, a lower wing plate 2, a machine core 3 and a pulling piece 6, wherein the upper wing plate 1 and the lower wing plate 2 are arranged in parallel up and down and are connected through the machine core 3, the left side and the right side of the upper wing plate 1 and the left side and the right side of the lower wing plate 2 are also correspondingly provided with side wing plates 4, the machine core 3 comprises a guide pillar 31 and a sealing pillar 32 which are of an integral structure, and the sealing pillar 32 is matched with a sealing groove of a front code 10.
Wherein, zipper strip 7, sprocket 8 can adopt the polymer material, have better sealed water-proof effects, preceding sign indicating number then adopts the TPU material to make with the back sign indicating number, have certain elastic deformation ability, and have better sealed water-proof effects.
The sealing coating and the sealing strip 9 are also made of TPU materials, so that a reliable airtight and waterproof effect is achieved.
When the zipper is pulled up, the zipper teeth 8 on the two zipper strips 7 are mutually meshed, the sealing column 32 of the machine core 3 is embedded into the sealing groove of the front code 10 to realize sealing fit therewith, the guide column 31 of the machine core 3 is in close contact with the sealing strip 9 to realize sealing, the free ends of the rest parts of the two sealing strips 9 are in close contact to realize sealing fit and cover the zipper teeth, and the airtight and waterproof effects of the zipper are realized through the sealing of the sealing coating and the sealing strip 9.
The lower wing plate 2 is provided with a sealing boss 5, the sealing boss 5 is arranged on two sides of the guide post 31, as shown in fig. 2, the cross section of the guide post 31 is triangular, and the sealing boss 5 correspondingly forms a V shape.
When the zipper is pulled, the sealing boss 5 can extrude the sealing strips on two sides of the guide pillar 31, so that the height difference is eliminated, the sealing strips are further guaranteed to be compressed, a better contact effect is achieved, and a better airtight and anti-leakage effect is achieved.
The sealing boss 5 further has an extension part 51 extending to the rear end, further extending the extrusion length of the sealing boss 5, so that the stress is more balanced and stable.
Certainly, the whole width of sealed boss 5 only need be slightly more than the width of core 3 alright, sealed boss 5's both sides limit keeps enough spacing distance with the flank board, sealed boss 5's extension length also need not too long, and its rear end also keeps spacing distance with the rear end of lower wing board 2, when guaranteeing effective extrusion, reduces area of contact as far as possible, reduces the friction between sealed boss 5 and sealing strip 9 for the action of operation zipper puller is lighter convenient.
In addition, the pull tab 6 is provided on the upper wing plate 1.
In the conventional airtight zipper, which is usually installed in a reverse direction, that is, when the airtight zipper is installed, the zipper teeth are located on the inner side (the side to be sealed) and the sealing tape is located on the outer side (the side to be used for operation), so that the lower wing plate is correspondingly located on the outer side, and the pull tab is usually located on the lower wing plate for the convenience of zipper operation, but when the pressure on the inner side reaches a certain value, the airtight zipper is deformed outward and the sealing tape is spread to cause leakage.
When pulling-on piece 6 sets up on last pterygoid lamina 1, the zip fastener can forward installation, and when installing airtight zip fastener promptly, the sprocket is located the outside, and the sealing strip is located the inboard, consequently goes up pterygoid lamina 1 and corresponds the setting in the outside, when inboard pressure reaches the airtight zip fastener of a definite value and can outwards warp, the sealing strip then can be better laminate each other to reach better sealed, airtight effect is better.
The examples should not be construed as limiting the invention, but any modifications made based on the spirit of the invention are intended to be within the scope of the invention.
