Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As depicted in figs. 1 and 2, a kind of airtight waterproof zipper, including the zipper strip 2 with opening portion 1, zipper strip 2 is being opened
1 opposite edge of oral area is provided with the pair of right and left fastener stringer 4 being made of several zipper sprockets 3, and two fastener stringers 4 are total
With composition tooth chain band.Two fastener stringers 4 alternate after engaging in close-packed arrays, and two fastener stringers 4 are equipped with
The same pull head 5 for clamping two sides sprocket 3 makes the sprocket 3 of two sides be intermeshed or separate.
The both ends of two fastener stringers 4 are provided with the stop part to limit 5 sliding scale of pull head.Specifically
, the stop part for controlling the side that pull head 5 is abutted when two fastener stringers 4 fully open is stopped 6 to be lower, it will left and right two
The stop part for the side that pull head 5 is abutted when fastener stringer 4 completely closes stops 7 to be upper.
As shown in Figures 2 and 3, each fastener stringer 4 is made of the molding interior tooth chain 8 of doubling and outer tooth chain 9, interior tooth
Chain 8 is located at zipper installation interiors of products side, and outer tooth chain 9 is located at side outside zipper installation product；Interior tooth chain 8 and outer tooth chain 9
Doubling can form the sprocket 3 that a column have dual tooth chain.The two sides of each fastener stringer 4 are provided with by thermoplastic elastomer (TPE) structure
At waterproof layer 10.Since waterproof layer 10 is made of thermoplastic elastomer (TPE), while guaranteeing the waterproof performance of zipper, Neng Gouti
The flexibility of high waterproof slide fastener and make the waterproof slide fastener to any direction bend.
As shown in Figure 3 and Figure 4, each waterproof layer 10 be provided with towards the side of another waterproof layer 10 to cover
The sealing strip 11 of fastener stringer 4.Each sealing strip 11 is an integral structure with the waterproof layer 10 being connected, and by same material structure
At.The side of each sealing strip 11 towards another sealing strip 11 is provided with sealing inclined-plane 12, and sealing strip 11 is far from zipper tooth
The cross-sectional area of 4 side of chain is greater than the cross-sectional area close to 4 side of fastener stringer.After two fastener stringers 4 engage, it is located at
The sealing strip 11 of two 4 two sides of fastener stringer mutually squeezes, so that each sealing strip 11 can be towards on another sealing strip 11
Sealing inclined-plane 12 be in close contact, the tooth chain band after closure is enclosed in two sides waterproof layer 10 and sealing strip 11 is surrounded
In space, to reach two way seal effect.Specifically, the liquid such as water from zipper installation product outside via opening portion 1 leak to
It, need to be successively by being located at waterproof layer 10, fastener stringer 4 and position outside zipper installation product when zipper installs the inside of product
In the waterproof layer 10 of zipper installation interiors of products, because having twice airtight waterproof outpost, and then has dual-seal performance, to mention
High closed waterproof performance.
Specifically, as shown in figure 4, the sealing inclined-plane 12 on sealing strip 11 and another sealing strip 11 carries out mutually
When extruding, sealing strip 11 can be squeezed with the sealing surface any position on another sealing strip 11 far from the end face of tooth chain,
So that it is guaranteed that two fastener stringers 4 waterproof layer 10 after engagement can still provide for two way seal under the conditions of dislocation.
As shown in Figure 1, upper only 7 only 6 be all made of the both ends that thermoplastic elastomer (TPE) is molded in tooth chain band respectively with lower.Under
Only 6 be sealing block structure, and the inside of sealing block is embedded with a part of fastener stringer 4, and the side of sealing block and waterproof layer 10
It is fixedly connected.Stop 6 and the continuous formation of fastener stringer 4 due to lower, to guarantee to stop waterproof layer between 6 positioned at fastener stringer 4 and down
10 watertightness, so that the fastener stringer 4 that will be close to down only 6 regions is sealed.
Above stopping 7 is flexible sealing ring 13, the sealing ring 13 form letter-c-shaped in main view.Sealing ring 13
Interior edge be provided with the sealing ribs 14 to fix pull head 5.Sealing is connected in the pull head 5 slided along the engagement direction of tooth chain band
Rib 14 and when stopping, user continues to slide pull head 5 in this case, and pull head 5 squeezes the sealing ribs 14 on both sides, forces
Sealing ribs 14 are moved away from the direction of pull head 5, so pull head 5 can break through sealing ribs 14 with enter sealing ring 13 in,
So that the upper and lower end faces of pull head 5 and sealing ring 13 are in close contact each other, so that it is guaranteed that the upper only watertight between 7 and pull head 5
Property.It removes, avoids with latent under certain hydraulic pressure environment out of sealing ring 13 at this point, sealing ribs 14 can play limitation pull head 5
Water clothes pull 5 position of pull head under the conditions of maloperation, to improve the safety of airtight waterproof zipper.When user is by pull head 5
When skidding off out of sealing ring 13, the extruding force from sealing ribs 14 need to be equally overcome.
Further, for pull head 5 for engaging and disengaging tooth chain, the side of pull head 5 is provided with the fixation nose 15 with through-hole,
The side of fixed nose 15, which is hinged with, to exert a force convenient for user with the pulling-on piece 16 for driving pull head 5 to slide.
Further, it is fixedly connected at the c-shaped opening of sealing ring 13 with waterproof layer 10.
Further, the two sides of each zipper strip 2 are coated with the thermoplastic material with waterproof performance, thermoplastic material
For PU polyurethane or polychlorobutadiene.So that zipper strip 2 has waterproof performance.
Further, each sealing strip 11 is an integral structure with the waterproof layer 10 being connected, and by thermoplastic elastic
Body is constituted.The thermoplastic elastomer (TPE) is preferably TPU.
