Abstract
The utility model discloses a novel resin airtight waterproof zipper, which is characterized in that TPU (thermoplastic polyurethane) is coated on high-strength fabric tapes to wrap all the fabric tapes via moulds, an elastic coupling surface attached with the TPU (thermoplastic polyurethane) is formed at the edge of the wrapped high-strength fabric tapes, high-strength resin teeth are fixed onto a chain belt by an upper portion sprocket and a lower portion sprocket via pins, the resin teeth are closed integrally, the elastic coupling surface attached with the TPU (thermoplastic polyurethane) at the edge of the fabric tapes can be combined integrally to enable gaps of the zipper and zipper teeth to be sealed effectively. By adopting the wrap of the TPU (thermoplastic polyurethane) and an overall design, the zipper can achieve the advantages of waterproof and vapor-proof effects, ultraviolet protection, corrosion prevention, aging resistance, wear resistance and the like.
Description
Technical field
The utility model relates to the slide fastener technical field, a kind of specifically waterproof slide fastener.
Background technology
Normally used air-tight water-proof slide fastener substantially all is the chain belt that adopts waterproof material to make, and by the fixing chain belt of engaging tooth, plays waterproof effect.Now the zipper strip waterproof material that uses on the market is very expensive, and many environment is polluted.So at above shortcoming by analysis, improve and to have made a kind of new waterproof slide fastener of saving cost, environmental protection and economy, waterproof durable.Can be widely used in military project, national defence, aviation, space flight and chemical industry etc.
The utility model content
The purpose of this utility model is for providing a kind of waterproof, gas-tight, and antiultraviolet, anticorrosion, anti-aging, the new waterproof slide fastener of advantage such as wear-resistant.
The technical scheme that realizes the foregoing invention purpose is as follows:
A kind of new type resin air-tight water-proof slide fastener, comprise chain belt and sprocket, it is characterized by: the surface of described chain belt is coated TPU (thermoplastic polyurethane) by mould chain belt is all enveloped, high-strength chain belt edge after coating forms an elasticity coupling surface with TPU (thermoplastic polyurethane), described thermoplastic polyurethane layer infiltrates the chain belt slit, forms mixed layer with chain belt.Described sprocket is divided into the identical upper and lower two parts of shape, and upper and lower two parts sprocket is fixed on the chain belt by pin.
Described sprocket contacts with chain belt and partly is positioned at the chain belt edge, makes chain belt edge elasticity coupling surface stretch out the sprocket contact portion.
Described new type resin air-tight water-proof slide fastener is characterized by: the elasticity coupling surface width that described chain belt stretches out the sprocket contact portion is 0.5mm.
The utility model is not easy come off in the washing process in the future, and is durable, and have that cost is low, the characteristics of good water-proof effect, environmental protection, split type sprocket strengthens the resistance to tension of slide fastener greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Dotted line represents that the outside of sprocket and chain belt contact portion is along the line among the figure.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of new type resin air-tight water-proof slide fastener, comprise chain belt 1 and resin sprocket 2, the surface of described chain belt is coated TPU (thermoplastic polyurethane) by mould chain belt is all enveloped, high-strength chain belt edge after coating forms an elasticity coupling surface 4 with TPU (thermoplastic polyurethane), described thermoplastic polyurethane layer infiltrates the chain belt slit, forms mixed layer with chain belt.Described sprocket is divided into the identical upper and lower two parts of shape, upper and lower two parts sprocket 2 is fixed on the chain belt 1 by pin 3, described sprocket contacts with chain belt and partly is positioned at the chain belt edge, make chain belt edge elasticity coupling surface stretch out the sprocket contact portion, the width 4 that described chain belt stretches out sprocket contact portion elasticity coupling surface is 0.5mm.
After the resin sprocket on slide fastener both sides was fastened to each other, the centre accompanied chain belt, and the lucky engaging tooth of chain belt extension is bitten part half mutually, working as slide fastener is like this pulled on, after 2 part engaging tooths were stung tightly, two parts meshed the chain belt that stretches out of toothholder, fit like a glove together.
The utility model can be made by following technology: chain belt is general terylene goods in this practical product.The chain band coating is to be applied on the chain belt by TPU (thermoplastics type's polyurethane) particles fuse, this mode can make marine glue and chain belt fully permeate, be not easy coming off in the washing process in the future, at last upper and lower two parts sprocket be fixed on the chain belt, load onto pull head and get final product.
Claims (3)
1. new type resin air-tight water-proof slide fastener, comprise chain belt and sprocket, it is characterized by: the surface of described chain belt is coated thermoplastic polyurethane by mould chain belt is all enveloped, high-strength chain belt edge after coating forms the elasticity coupling surface of a thermoplastic polyurethane, described thermoplastic polyurethane layer infiltrates the chain belt slit, form mixed layer with chain belt, described sprocket is divided into the identical upper and lower two parts of shape, and upper and lower two parts sprocket is fixed on the chain belt by pin.
2. new type resin air-tight water-proof slide fastener according to claim 1 is characterized by: described sprocket contacts with chain belt and partly is positioned at the chain belt edge, makes chain belt edge elasticity coupling surface stretch out the sprocket contact portion.
