Abstract
The utility model relates to a coreless zipper. The coreless zipper comprises a pull head, an upper dead, a lower dead and a pair of zipper belts, wherein the pull head, the upper dead and the lower dead are arranged on the pair of zipper belts; a ribbon is arranged in each zipper belt; each zipper belt is formed by interweaving longitude lines and latitude lines; the ribbon is formed by multiple strands of longitude lines; and the ribbon is connected with the zipper belt through the latitude line. In comparison with the prior art, the coreless zipper has the advantages of being low in machining cost, safe and reliable to use, favorable in smoothness and long in service life.
Description
Technical field
The utility model relates to a kind of slide fastener, and particularly a kind of centreless slide fastener belongs to a kind of articles for daily use.
Background technology
Existing slide fastener all has a pair of zipper strip, and all is provided with middle heart yearn in the zipper strip.This existing slide fastener has following shortcoming: the one, and it need use the good middle heart yearn of special-purpose braider braiding earlier, the warp of middle heart yearn as zipper strip is contained on the braider of woven cloth again, is woven together with other warp, parallel again.Such action need two procedures, complex procedures, and need two kinds of different braiders, increased cost.Because intensity difference to some extent between middle heart yearn and the zipper strip, make whole poor mechanical property.Be prone to displacement, distortion during sprocket is contained on the heart yearn, influence the life-span of whole piece slide fastener.Smoothness is poor during the zipper head pulling, because middle heart yearn is the cord that is woven into, and the shape spirality; Middle heart yearn can exist concavo-convex, and sprocket will produce small height and cause parallelism error after being contained on the middle heart yearn between each sprocket; Can feel the cunning that has some setbacks when therefore, people use zipper head.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, and simple in structure, easy to use, cost is low, and is easy to process, and the pull head pulling is along sliding centreless slide fastener.
The utility model addresses the above problem the technical scheme that is adopted: this centreless slide fastener; It is characterized in that: comprise pull head, go up and end, end down and a pair of zipper strip; Said pull head, go up to end and only all be installed on a pair of zipper strip down, all be provided with the band muscle in said every zipper strip, said every zipper strip all is interwoven by warp and parallel; Said band muscle is made up of the multiply warp, and this band muscle is connected through parallel with zipper strip.
The said band muscle of the utility model is positioned at a side of zipper strip.
The utility model compared with prior art, have the following advantages and effect: processing cost is low, and is safe and reliable, smoothness is good, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 be the utility model embodiment band muscle and zipper strip be connected sketch map.
Fig. 3 is the band muscle of the utility model embodiment and the cross-sectional schematic of zipper strip.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
Embodiment.
Extremely shown in Figure 3 like Fig. 1; The centreless slide fastener of present embodiment comprises a pair of zipper strip 1, pull head 2, upward ends 3 and end 4 down; Pull head 2, upward end 3 and end 4 down and all be installed on the zipper strip 1, be provided with band muscle 5 in the zipper strip 1, zipper strip 1 is interwoven by warp 11 and parallel 12; Band muscle 5 is made up of multiply warp 11, and this band muscle 5 is connected through parallel 12 with zipper strip 1.Band muscle 5 is positioned at a side of zipper strip 1, and the band muscle 5 of left side zipper strip 1 is positioned at its right side, and the band muscle 5 of the right zipper strip 1 is positioned at its left side, makes the band muscle 5 of two zipper strips 1 adjacent.Band muscle 5 is provided with sprocket.
Because band muscle 5 is to have multiply warp 11 to constitute, make that band muscle 5 smoothness are good, intensity is high, and is easily manufactured, and band muscle 5 intensity are high, tension uniform, sprocket is difficult for displacement, distortion when using, and smoothness is good during pull head 2 pullings.
When using, up spurring pull head 2 just can be so that the mutual interlock of sprocket, zip up; Pulled down pull head 2 just can unzip so that sprocket is separated from each other.
Above content described in this specification only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
Claims (2)
1. centreless slide fastener; It is characterized in that: comprise pull head, go up and end, end down and a pair of zipper strip; Said pull head, go up to end and only all be installed on a pair of zipper strip down, all be provided with the band muscle in said every zipper strip, said every zipper strip all is interwoven by warp and parallel; Said band muscle is made up of the multiply warp, and this band muscle is connected through parallel with zipper strip.
2. centreless slide fastener according to claim 1 is characterized in that: said band muscle is positioned at a side of zipper strip.
