State the sealing of the sealing lip of fin.A kind of specific sealing structure is disclosed, which can couple when zipper is closed
The top of element forms a sealing structure to reach air-tightness requirement.The sealing structure is when two coating of zipper are due to contact
Mutual mutual extrusion, easily occurring in coating, there is a situation where be unable to satisfy air-tightness requirement, overall structure after certain deformation
Stability is not strong.
Utility model content
Therefore, in view of the above-mentioned problems, the utility model provides, a kind of sealing effect with multi-sealing structure is good to be prevented
The close zipper of aqueous vapor.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions:
A kind of waterproof airtight zip fastener that sealing effect is good, including two straps, the opposite side of two straps are respectively equipped with chain tooth,
The upper surface of two straps is coated with waterproof layer, and sealing lip is respectively arranged with above the chain tooth of the opposite side of two straps, sealing
Lip is Nian Jie with waterproof layer, and in one, two sealing lips are opposite and arranged symmetrically, and the sealing lip includes upper lip and lower lip, lower lip with
Upper lip extends the edge of strap, and when the chain tooth closure being arranged on cloth band, the lower lip and upper lip on two cloth bands are inconsistent,
The section of two upper lips is in hook formation, and free ending tool has the extension extended downwardly, when the chain tooth closure being arranged on cloth band,
Extension on two upper lips is bonded to each other.
Preferably, the chain tooth winds center line by heated die by nylon monofilament and forms the spiral with intermediate gaps
Formula structure inserts a waterproof edge sealing in the intermediate gaps of two sides chain tooth, and two waterproof edge sealings are glued respectively to two strap phases
On the side of adjacent side, and the lower end edge of the strap is extended downwardly out, when chain tooth is mutually twisted, the two waterproof edge sealings phase
Mutually abut.
Preferably, the waterproof layer and sealing lip are all made of memory plastics.
By using preceding solution, the beneficial effects of the utility model are: the utility model is using setting with upper
Lip, two extension ends of lower lip structure of sealing lip, two sides sealing lip fitting when, be capable of forming upper and lower secondary containment space,
The surface of the design of both sides sealing lip symmetrical structure, two sides upper lip extension abuts, and forms the biggish face contact of area and seals, under two
Lip abuts, and sealing cavity is formed between upper lip and lower lip, has be more good sealing effect compared with traditional sealing structure,
The stability of sealing structure is stronger, and sealing effect is more preferably.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment one；
Fig. 2 is the structural schematic diagram that pinch roller and mold are formed in one shaping mechanism of the utility model embodiment
Fig. 3 is the overall structure diagram of the utility model embodiment two.
Specific embodiment
The embodiments of the present invention is described in detail below with reference to specific embodiment, whereby such as to the utility model
What applied technology method solves technical problem, and the realization process for reaching technical effect can be fully understood and implemented.
Embodiment one
With reference to Fig. 1, a kind of waterproof airtight zip fastener that sealing effect is good, including two straps 1, the opposite side of two straps 1 point
Not She You chain tooth, the upper surface of two straps 1 is coated with waterproof layer 2, is respectively set above the chain tooth of the opposite side of two strap 1
There is sealing lip 3, sealing lip 3 is Nian Jie with waterproof layer 2 in one, and two sealing lips 3 are opposite and arranged symmetrically, and the sealing lip 3 includes
Upper lip 31 and lower lip 32, lower lip 32 and upper lip 31 extend the edge of strap 1, when the chain tooth closure being arranged on strap 1,
Lower lip 32 and upper lip 31 on two straps 1 is inconsistent, and the section of two upper lips 31 is in hook formation, and free ending tool, which has, to be stretched downwards
Extension 311 out, when the chain tooth closure being arranged on cloth band, the extension 311 on two upper lips is bonded to each other.
With reference to Fig. 2, sealing lip 3 described in the utility model at the time of molding, by a shaping mechanism, will heat state
