Abstract

The utility model relates to a double-layer nylon slide fastener which comprises a sliding pull head (3) and two chains (5); each chain (5) comprises a cloth band (1) and a plurality of occlusal chain teeth (2); the cloth band (1) is folded into an upper layer and a lower layer along the length direction; the occlusal chain teeth (2) are respectively fixed on the upper layer and the lower layer of cloth band (1) and are tightly close to the folded bending part to form two layers of the occlusal chain teeth (2) overlapped at the upper side and the lower side; the upper layer and the lower layer of the occlusal chain teeth (2) on the cloth band (1) are respectively opposite to each other at the upper side and the lower side; the sliding pull head (3) is configured to be matched with the occlusal chain teeth (2); the sliding pull head (3) moves back and forth along the length direction of the chain (5) to drive the corresponding occlusal chain teeth (2) to be occluded or separated. The double-layer nylon slide fastener can enable the slide fastener to bear a larger tension so that the slide fastener is more durable.

Description

A kind of double-layer nylon slide fastener

Technical field:

The utility model relates to a kind of slide fastener, relates in particular to a kind of double-layer nylon slide fastener.

Background technology:

Existing slide fastener is the individual layer slide fastener, is made up of individual layer strap and single-row chain tooth.When the individual layer slide fastener was applied on the product of some high-tensions, if afford excessive tension force, occurring easily can't be closed between the chain tooth, or the problem of splitting easily and rupturing of the suture on the strap.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective in the conventional art, and a kind of double-layer nylon slide fastener is provided, and makes slide fastener can bear bigger tension force, and is more durable.

For achieving the above object, the technical scheme that provides of the utility model is as follows:

A kind of double-layer nylon slide fastener, comprise the slip pull head, article two, chain, every chain comprises strap and a plurality of meshing chain tooth, described strap is folded in half into two-layer up and down separately along its length, the meshing chain tooth is separately fixed on the described two-layer strap up and down and near the doubling bending part, form the overlapping shape of two-layer meshing chain tooth up and down, two, two is relative about the meshing chain tooth difference on strap is two-layer up and down, described slip pull head have with the meshing chain tooth be complementary ccontaining, the slip pull head moves around along the chain length direction, drives mutual interlock of corresponding meshing chain tooth or separation.

Wherein, the meshing chain tooth is fixed on the strap by suture.

The utility model can make slide fastener bear bigger tension force, makes slide fastener more durable.

The specific embodiment

Below be the embodiment of double-layer nylon slide fastener described in the utility model, as shown in Figure 1 and Figure 2:

A kind of double-layer nylon slide fastener, comprise slip pull head 3, article two, chain 5, every chain 5 comprises strap 1 and a plurality of meshing chain tooth 2, described strap 1 is folded in half into two-layer up and down separately along its length, meshing chain tooth 2 is separately fixed on the described two-layer strap 1 up and down and near the doubling bending part, form two-layer meshing chain tooth 2 overlapping shapes up and down, strap is the meshing chain tooth on two-layer 2 respectively two about in the of 1, two is relative, described slip pull head 3 have with meshing chain tooth 2 be complementary ccontaining, slip pull head 3 moves around along chain 5 length directions, drives corresponding meshing chain tooth 2 mutual interlock or separation.

Wherein, meshing chain tooth 2 is fixed on the strap 1 by suture 4.

Claims

1. double-layer nylon slide fastener, comprise slip pull head (3), article two, chain (5), it is characterized in that, every chain (5) comprises strap (1), a plurality of meshing chain teeth (2), described strap (1) is folded in half into two-layer up and down separately along its length, meshing chain tooth (2) is separately fixed on the described two-layer strap (1) up and down and near the doubling bending part, form the overlapping up and down shape of two-layer meshing chain tooth (2), meshing chain tooth (2) on strap (1) is two-layer up and down respectively up and down two, two is relative, described slip pull head (3) have with meshing chain tooth (2) be complementary ccontaining, slip pull head (3) moves around along chain (5) length direction, drives corresponding meshing chain tooth (2) interlock or separation mutually.
