Abstract

The utility model discloses an airtight waterproof zipper, and relates to the field of zipper manufacturing. The airtight waterproof zipper consists of sprocket chain belts (1), a catching groove chain belt (2), button chain teeth (3), and catching groove chain teeth (4), wherein a plurality of button chain teeth (3) are uniformly and tightly formed on the sprocket chain belt (1); a plurality of catching groove sprockets (4) which correspond to the button chain teeth (3) are tightly and uniformly formed on the catching groove chain belt (2); and the sprocket chain belt (1) and the catching groove belt (2) are fastened and engaged with each other by the button chain teeth (3) and the catching groove sprockets (4). The zipper has a high waterproof property under high pressure, is easy to manufacture, and has a good sealing effect and flexibility, and the cost is reduced.

Description

A kind of air-tight water-proof slide fastener

Technical field:

The utility model relates to art of zipper fabrication, relates in particular to a kind of air-tight water-proof slide fastener.

Background technology:

Along with human social economy and science and technology development, to nonmetallic materials, the single variety function develops to many specifications comprehensive function slide fastener by initial metal material; By simple structure exquisite attractive in appearance, colourful to today, passed through very long evolution process; The effect that slight slide fastener plays in people's life is increasing, more and more shows its importance, and existing slide fastener does not possess water proofing property; Waterproof slide fastener only just has in Japan and Germany, and these two kinds of slide fasteners are very complicated because of manufacturing process, material expensive; So cost is very high, be difficult to obtain popularize and be widely used, and color all is single black; This kind slide fastener majority can only be as in the industry, and is if be used in civilian or be used on the product that color requires, very not attractive in appearance.

The utility model content:

The purpose of the utility model provides a kind of air-tight water-proof slide fastener, and it can under high pressure have good water resistance, and it is simple to make industry, and good sealing effect has pliability, has reduced cost.

In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it is made up of buckle teeth chain belt 1, catching groove chain belt 2, button sprocket 3, catching groove sprocket 4; Evenly closely be provided with several button sprockets 3 on the buckle teeth chain belt 1, evenly closely be provided with several and button sprocket 3 corresponding catching groove sprockets 4 on the catching groove chain belt 2, and buckle teeth chain belt 1 and catching groove chain belt 2 are through button sprocket 3 and the 4 mutual snapping interlocks of catching groove sprocket.

Described slide fastener is to be interlocked by the chain tooth on two buckle teeth chain belts 1 to form, and utilizes the range difference squeeze buckle toothed chain band 1 of 3 of buckle teeth chain belt 1 button bit and button sprockets let the both sides driving fit, reaches the air-tight water-proof effect.

Described buckle teeth chain belt 1 can use material different also can reach the air-tight water-proof effect according to the Different products requirement with button sprocket 3, and sprocket 1 can also be changed color with chain belt 2, and is very easy to use, can use number of various materials according to the environment that uses.

The angle of two chain between cog can reach 12 ° when the utility model was just curved, and the angle of two sprockets can reach 15 ° during lateral bending, and the angle of two sprockets of distortion can reach 3 °, so can not cause damage and leak slide fastener, has very big pliability.

The utility model is at high temperature 65 degree; Still can reach the air-tight water-proof effect under the subzero 20 degree situation of low temperature; The every 100mm of pulling force that horizontal slide fastener bears can reach 40KG; Vertical tension can reach to throw away under the situation of 20KG and can reach the air-tight water-proof effect, puts on the way to let the dolly of 1.8 tons of weights roll repeatedly, throws away and can normally use.

The utility model can under high pressure have good water resistance, and it is simple to make industry, and good sealing effect has pliability, has reduced cost.

The specific embodiment:

With reference to Fig. 1-Fig. 9, this specific embodiment adopts following technical scheme: it is made up of buckle teeth chain belt 1, catching groove chain belt 2, button sprocket 3, catching groove sprocket 4; Evenly closely be provided with several button sprockets 3 on the buckle teeth chain belt 1, evenly closely be provided with several and button sprocket 3 corresponding catching groove sprockets 4 on the catching groove chain belt 2, and buckle teeth chain belt 1 and catching groove chain belt 2 are through button sprocket 3 and the 4 mutual snapping interlocks of catching groove sprocket.

The angle of two chain between cog can reach 12 ° when this specific embodiment was just curved, and the angle of two sprockets can reach 15 ° during lateral bending, and the angle of two sprockets of distortion can reach 3 °, so can not cause damage and leak slide fastener, has very big pliability.

This specific embodiment is at high temperature 65 degree; Still can reach the air-tight water-proof effect under the subzero 20 degree situation of low temperature; The every 100mm of pulling force that horizontal slide fastener bears can reach 40KG; Vertical tension can reach to throw away under the situation of 20KG and can reach the air-tight water-proof effect, puts on the way to let the dolly of 1.8 tons of weights roll repeatedly, throws away and can normally use.

This specific embodiment can under high pressure have good water resistance, and it is simple to make industry, and good sealing effect has pliability, has reduced cost.
