Abstract

The utility model relates to an improved structure of a zipper strip, which is composed of a zipper head and two chains, wherein the zipper head is provided with a bundle groove which can bundle the top ends of the two chains; the inner side of the lower side of the bundle groove is provided with a hook part; the center of one end of the bundle groove is provided with a separate sheet; the two chains are parallel; the top end of one chain is provided with a folding part which is inward folded; in addition, the inner sides of the top ends of the two chains are respectively provided with buckling parts which can be mutually buckled; the positions of the outsides of the two chains, which are corresponding to a hook part of the zipper head, are provided with convex strips. When the bundle groove of the zipper head is bundled to the two chains, the hook part of the zipper head can be buckled with the convex strips of the outsides of the two chains. Thereby, when the zipper head is moved correspondingly to the two chains, and the buckling part of the two chains is folded or unfolded, the zipper head can not separate with the two chains. The utility model has good action stability.

Description

The zip strip structure-improved

Technical field

The utility model relates to a kind of zip strip structure-improved.

Background technology

Known bag or other suitable assemblies are for promoting the folding convenience, and the sealing part of the bag of being everlasting is provided with two rectangular chain structures, and buckling parts is set on chain, make the user can push the two chain buckling parts driving fits of chain regulations or the application of force makes chain launch action.

Yet aforementioned structure all just can make the complete driving fit of two chains because of the user must push two strip chains, causes the inconvenient situation of operation, and easily produces the not driving fit and cause the not good disappearance of adaptation of two portion of chain positions.

This fastening intensity of pushing fastening structure is not good again, when being subjected to external force when collision, easily causes chain after the driving fit to break away from the disappearance of buckling state.

And for example shown in Figure 5, known bag also has at sealing part two parallel chains 1 ', 2 ' is set, cooperate slider of zipper fastener 3 ' design again, and this two chain 1 ', 2 ' has buckling parts 11 ', 21 ' respectively, and slider of zipper fastener 3 ' have can restraint close two chains 1 ', 2 ' bundle closes portion 31 ', make to make two chains 1 ', 2 ' buckling parts 11 ', 21 ' fasten or launch by slider of zipper fastener 3 ' displacement.

Yet aforementioned structure because of slider of zipper fastener 3 ' be by two chains 1 ', 2 ' flexiblely make bundle close portion's 31 ' bundle to close two chains 1 ', 2 ', when bestowing big external force, still easily cause slider of zipper fastener 3 ' and two chains 1 ', the 2 ' situation that breaks away from, therefore have the not good disappearance of combinative stability.

The utility model content

The purpose of this utility model is to provide a kind of zip strip structure-improved, and its bond stability that can promote zip strip and slider of zipper fastener comes off to prevent slider of zipper fastener.

For achieving the above object, technical solution of the present utility model is: a kind of zip strip structure-improved, combine by slider of zipper fastener, two chains, and this slider of zipper fastener has can restraint the joining slot that closes two chain tops, and the inboard is provided with the hook part below joining slot; Two chains are set in parallel again, and a chain top is provided with the kink that bends inwards therein, in inboard, two chain tops the buckling parts that can fasten each other are set respectively in addition; The outer position, routine corresponding slider of zipper fastener hook part of two chains is provided with raised line; After the joining slot bundle of slider of zipper fastener closes two chains, the raised line hook in the hook part of slider of zipper fastener and the two chains outside.

After adopting such scheme, because the utility model is provided with raised line in the position, hook part of the corresponding slider of zipper fastener in the two chains outside, after the joining slot bundle of slider of zipper fastener closes two chains, the hook part of slider of zipper fastener can with the raised line hook in the two chains outsides, therefore slider of zipper fastener displacement and make the buckling parts driving fit of two chains or when launching, slider of zipper fastener can not break away from two chains, thereby has preferable action stability.

The specific embodiment

See also Fig. 1 to shown in Figure 4, the utility model embodiment is combined by slider of zipper fastener 1, two

chains

2,3, and this slider of zipper fastener 1 has and can restraint the joining slot 11 that closes two chains, 2,3 tops, and the inboard is provided with hook part 12 below joining slot 11, is provided with partition 13 in joining slot 11 1 end central authorities again;

Two

chains

2,3 are set in parallel, and a chain 2 tops are provided with the kink 21 that bends inwards therein, this chain 2 can make in the bottom by kink 21 and launch laterally, in inboard, two chains, 2,3 top the

buckling parts

22,31 that can fasten each other is set respectively again, and this

buckling parts

22,31 is provided with button 221,311 and buckling groove 222,312, and 12 positions, corresponding slider of zipper fastener 1 hook part are provided with raised

line

23,32 in two chains, 2,3 outsides again.

Claims

1, a kind of zip strip structure-improved is combined by slider of zipper fastener, two chains, and this slider of zipper fastener has can restraint the joining slot that closes two chain tops, and the inboard is provided with the hook part below joining slot; Two chains are set in parallel again, and a chain top is provided with the kink that bends inwards therein, in inboard, two chain tops the buckling parts that can fasten each other are set respectively in addition; It is characterized in that: position, corresponding slider of zipper fastener hook part, the two chains outside is provided with raised line; After the joining slot bundle of slider of zipper fastener closes two chains, the raised line hook in the hook part of slider of zipper fastener and the two chains outside.
