Abstract

The utility model discloses an airtight zip fastener, a serial communication port, include: a fastener tape and a fastener head; thickened reinforcing ribs, waterproof glue layers, sprocket heads and woven cloth belts are symmetrically arranged on two sides of the zipper strips from top to bottom in sequence; after the sprocket heads are folded, the reinforcing ribs on the two sides form a bulge. Compared with the prior art, the utility model has the advantages that the waterproof glue layer is extruded and molded at one time outside the common zipper cloth belt, the thickened reinforcing rib is formed at the central part of the waterproof glue layer at one time, when the zipper teeth are extruded and occluded with each other, the reinforcing ribs at two sides are closed to form a bulge, so that the contact surface of the zipper is small and neat, and the bending radius is small, thereby enhancing the airtight and waterproof effects of the zipper pair and forming an airtight zipper which is completely waterproof and breathable; in addition, the waterproof glue layer is injected outside the zipper, so that the service life of the zipper is prolonged to a certain extent, and the zipper is more economical and practical and is suitable for mass production and wide popularization.

Description

Airtight zipper
Technical Field
The utility model relates to a zip fastener technical field, more specifically the airtight zip fastener that says so relates to.
Background
A zipper is a connecting piece for combining or separating articles by means of continuously arranged zipper teeth, and is widely used in the fields of clothes, bags, tents and the like at present. The traditional zipper has poor air-tight and water-proof performance because of the defects of the structural design and the gap between the closed zipper and the core part.
Therefore, how to provide an airtight zipper that can solve the above problems is a problem that needs to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an airtight zipper which can not only well prevent water permeation and ensure air tightness in low-temperature and humid environments; and the whole body is formed by one-time extrusion injection, so that the service life of the plastic pipe is prolonged, and the plastic pipe is practical and economical.
In order to achieve the above object, the utility model provides a following technical scheme:
an airtight zipper characterized by comprising: a fastener tape and a fastener head; thickened reinforcing ribs, waterproof glue layers, sprocket heads and woven cloth belts are symmetrically arranged on two sides of the zipper strips from top to bottom in sequence; after the sprocket heads are folded, the reinforcing ribs on the two sides form a bulge.
Preferably, in the above airtight slide fastener, a waterproof adhesive layer is injection-molded on both of the front and back fastener element head coupling portions of the fastener tape; the waterproof glue layer is formed by one-time extrusion injection molding.
Preferably, in the above airtight slide fastener, a reinforcing rib of waterproof adhesive is formed at a position near the head of the fastener tape at the center thereof at one time.
Preferably, in the above airtight zipper, the reinforcing ribs are arranged oppositely, and when the zipper tooth heads are engaged by the zipper head, the formed protrusions are matched with the waterproof glue layers on the two sides to form a tight integrated body which is extruded mutually, so as to achieve the purposes of airtightness and waterproofness.
Preferably, in the above airtight slide fastener, both upper and lower ends of the fastener tape are sealed by a waterproof adhesive layer.
Preferably, in the airtight slide fastener, the fastener element head is made of a nylon material.
According to the technical scheme, compared with the prior art, the waterproof adhesive layer is extruded and molded at one time outside the common zipper cloth belt, the thickened reinforcing rib is formed at the central part of the waterproof adhesive layer at one time, and after the zipper tooth heads are extruded and occluded with each other, the reinforcing ribs on two sides are closed to form a bulge, so that the contact surface of the zipper is small and neat, and the bending radius is small, thereby enhancing the airtight and waterproof effects of the zipper pair and forming a completely waterproof and breathable airtight zipper; in addition, the waterproof glue layer is injected outside the zipper, so that the service life of the zipper is prolonged to a certain extent, and the zipper is more economical and practical and is suitable for mass production and wide popularization.
