Abstract
The utility model provides a zip fastener of improvement structure belongs to zip fastener technical field. It has solved heart yearn yi songtuo's in the present zip fastener problem. This zip fastener of improvement structure, including strap, sprocket and well heart yearn, the sprocket is connected on the strap, and well heart yearn alternates in the sprocket, and the net nested structure that forms is woven for a plurality of root heart yearn intercrossing to well heart yearn. It with well heart yearn system for the net nested structure, each root heart yearn each other crisscross and winding difficultly produces the pine and takes off together, makes sprocket convenient and fast more in the time of the installation simultaneously, the life of zip fastener is longer.
Description
Technical field
The utility model belongs to zipper technology field, relates to a kind of slide fastener, particularly a kind of structure improved slide fastener.
Background technology
Slide fastener (zipper) relies on continuously arranged chain tooth, makes article and the connector closing or be separated.Slide fastener comprises nylon zipper by materials classification, resin teeth zipper and metal zip fastener, and nylon zipper can be used in all kinds of occasion, but generally prefers to be used on gym suit, footwear, bed clothes, case and bag, tent.General nylon zipper is made up of strap, sprocket, pull head etc., wherein sprocket is fixed on strap and forms tooth chain band, heart yearn composition during the sprocket nylon monofilament of nylon zipper is wound around by heated die, existing middle heart yearn is the twisted line that multi cord is formed, very easily get loose, the end of a thread got loose easily is leant out by the gap of chain tooth, affects the sliding of pull head on tooth chain band, in addition when pull head is by after chain tooth is deviate from, the end of a thread got loose can make the inconvenience of reinstalling very of pull head.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of structure improved slide fastener, and its middle heart yearn is woven into nets structure by multi cord, not easily gets loose.
The purpose of this utility model realizes by following technical proposal: a kind of structure improved slide fastener, comprise strap, sprocket and middle heart yearn, described sprocket is connected on strap, described middle heart yearn interts in sprocket, it is characterized in that, described middle heart yearn is the nets structure of the mutual interlacing of some root heart yearns.
In the technical program, middle heart yearn is made as nets structure, and each root heart yearn is interlaced and be intertwined, and not easily produces and gets loose, convenient time sprocket is installed, longer service life simultaneously.
In above-mentioned structure improved slide fastener, the radical of described heart yearn is 18 ~ 30.More radical heart yearn the nets structure that weaves not easily get loose, fastness is better, and due to heart yearn quantity more, even if there are several heart yearns on a small quantity to get loose, its end of a thread deviate from also easily wrap up by other heart yearn, not easily leak outside.
In above-mentioned structure improved slide fastener, the radical of described heart yearn is 20 ~ 26.
In above-mentioned structure improved slide fastener, described heart yearn is formed by some polyester thread twisteds.The core structure intensity of twisted is higher.
In above-mentioned structure improved slide fastener, the radical of described polyester thread is 10 ~ 30.
In above-mentioned structure improved slide fastener, described strap comprises some warp thread and some and the cross one another weft yarn of above-mentioned warp thread, and described warp thread is arranged along the length direction of strap, and described warp thread and weft yarn are made by dacron thread.Dacron thread structural strength is high, not yielding after sizing, longer service life.
In above-mentioned structure improved slide fastener, described weft yarn is that former black dacron thread is made, and described warp thread is that the black terylene silk of poach dyeing is made.The dacron thread of black has stain preferably, the black terylene silk of dyeing is relative to former black dacron thread, there is better blackness and glossiness, fastness is better simultaneously, the warp thread be positioned on strap length direction is made up of the dacron thread dyeing, is conducive to the structural strength and the practicality that improve strap.
In above-mentioned structure improved slide fastener, described warp thread and weft yarn are former black dacron thread and make.The dacron thread of black has stain preferably, and the price of former black dacron thread is lower, warp thread and weft yarn is made by former black dacron thread, is conducive to reducing production cost.
Compared with prior art, the utility model has following advantage:
1, the middle heart yearn of this slide fastener is made as nets structure, and each heart yearn is interlaced and be intertwined, and not easily produces and gets loose;
2, the strap of this slide fastener is woven by dacron thread and forms, and structural strength is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this slide fastener.
Fig. 2 is the middle heart yearn cross sectional representation of this slide fastener.
In figure, 1, strap; 11, warp thread; 12, weft yarn; 2, sprocket; 3, middle heart yearn; 31, sub-heart yearn.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
With reference to Fig. 1, the present embodiment is a kind of slide fastener, comprises strap 1, sprocket 2 and middle heart yearn 3, and sprocket 2 is connected on strap 1, and middle heart yearn 3 interts in sprocket 2, it is characterized in that, middle heart yearn 3 is the nets structure of the mutual interlacing of some root heart yearns 31.Middle heart yearn 3 is made as nets structure, and each root heart yearn 31 is interlaced and be intertwined, and not easily produces and gets loose, convenient time sprocket is installed, longer service life simultaneously.
Concrete structure is as follows, and the radical of the sub-heart yearn 31 of the middle heart yearn 3 of the present embodiment is 18 ~ 30, is preferably 20 ~ 26, more preferably as shown in Figure 2 24.
Sub-heart yearn 31 in the present embodiment can be a polyester thread, also can be formed by some polyester thread twisteds.
Composition graphs 1, strap 1 comprises some warp thread 11 and some and the cross one another weft yarn 12 of above-mentioned warp thread 11, and warp thread 11 is arranged along the length direction of strap 1.Warp thread 11 in the present embodiment and weft yarn 12 are made by dacron thread.When embody rule, if in order to cost-saving, warp thread 11 and weft yarn 12 can be made by former black dacron thread; If in order to make strap have better blackness, glossiness and fastness, the black terylene silk that warp thread 11 and weft yarn 12 dye by poach can be made; If in order to take into account economic benefit and fastness, the black terylene silk that warp thread 11 can be dyeed by poach is made, and weft yarn 12 is made up of former black dacron thread.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
