Description
Technical field
The pull head that the utility model belongs to slide fastener field more particularly to a kind of semicircle closes tail slide fastener and it is coordinated to use.
Background technology
Slide fastener is by continuously arranged chain tooth, makes article and the connector for closing or detaching, present slide fastener are largely used to
Clothes, bag, tent etc..Slide fastener is generally made of the fastener being respectively made of on two tooth chain bands row's metal-toothed or plastic teeth,
For connecting the edge (such as clothes or sack) of opening, having a sliding part (pull head) that can two toothrows be pulled in interlocking position makes opening
Closing.
Based on flat and chain tooth of the cross section as rectangle, this kind of slide fastener surface moulding is usually existing slide fastener
Plane, structure is single, and moulding is simple, can not meet the particular/special requirement of some consumers.Smoothness during slide fastener use is
User considers a very big reference standard of slide fastener, and smoothness not only influences comfort level when user uses, can also influence
The bulk life time of slide fastener.Existing slide fastener is susceptible to that slide fastener is not smooth enough, easily accelerates the abrasion of zipper tooth, and then causes to draw
Chain tooth occlusion dynamics is inadequate, and zipper closure is incomplete or even the situation of debentition occurs, reduces the whole service life of slide fastener.
Existing slide fastener, which is generally divided into, closes tail slide fastener and separating zipper, in tail slide fastener is closed, closes tail slide fastener when pulling open, both sides
Tooth chain band is not completely separated.Closing tail slide fastener can be divided into that single head closes tail slide fastener and double end closes tail slide fastener, and single head closes tail slide fastener and refers to
It wears there are one pull head, and only and down stops in setting on tooth chain band；Double end closes tail slide fastener and refers to wear that there are two pull head and two
Down only close tail slide fastener, two pull heads can backwards to or opposite folding.When tooth chain band upper and lower ends are only arranged under two, pull head is drawn
When opening tooth chain, slide fastener is in " O " type；When being only provided immediately on tooth chain band under two, when two pull heads pull open tooth chain, slide fastener is in
" X " type.
It is usually to set tight latch fitting in position of the tooth chain with lower end closely chain tooth to close tail slide fastener, and tight latch fitting is lower only structure,
Two rooted tooth chain belts pass through lower only structure combination, it is ensured that tooth chain band tail end is closed, and existing above only and down only the section of structure is general
For rectangle, the corner angle of end are easily using the process skin is made to be stimulated, upper only to be stung with the occlusal crib in lower only structure
When closing tooth chain band, due to its rectangular cross-section structure, snap-in force deficiency is susceptible to, is engaged and loosens, it is upper only to be taken off with lower stop
Situation about falling.
The patent of Patent No. CN201720299871.7 discloses a kind of circle and closes tail slide fastener, which includes, chain tooth,
It is lower only and tooth chain band, the section of chain tooth is semicircle, and the root portion of chain tooth ontology is equipped with left tooth symmetrically and right tooth, left tooth
Fan groove is formed with right tooth and root portion, fan groove is engaged on the inside of tooth chain band；It is lower to stop by two symmetrical arcuate structures
Composition, circle are closed tail slide fastener and are further included only, and above outside only is equipped with third occlusal crib, and third occlusal crib is engaged in tooth chain band
Inside.Two semicircle chain tooths are engaged to form circular zipper by this patent, although making slide fastener smooth, the material that chain tooth uses
Excessively, when and applying in clothing, due to being that circle can cause out-of-flatness, easily cause makes the side chain tooth positioned at tooth chain band
The sense of discomfort of user.

Third inner wall positioned at lower end occlusion portion 23 is horizontally or diagonally plane.Since lower the first occlusal crib 24 and second only in 2 is stung
By opening, first increases and then decreases, most inner side are arc structure to the width of conjunction slot 25 inwardly, and the first occlusal crib 24 and second sting
Close slot 25 be engaged tooth chain band when can be more convenient application snap-in force, two occlusal crib stress is made more to concentrate, occlusal crib with
Tight ness rating is coordinated to improve between tooth chain band, and occlusal crib is not susceptible to deform during use, avoids the occurrence of and is stung with tooth chain band
Close situation about loosening.It is respectively provided on the second inner wall of upper end occlusion portion 21 in the first occlusal crib 24 and the second occlusal crib 25
Recess 26 is clamped, in installation process, above-mentioned clamping recess 26 can be used for blocking tooth chain band, and preventing installation, anti-avulsion is fallen at present,
The innermost arc structure of occlusal crib may insure there is enough surpluses, occlusion tooth as much as possible when being engaged tooth chain band simultaneously
Chain belt, it is ensured that lower to stop the more secured of 2 installations.23 bottom surface of lower end occlusion portion for stopping 2 down is horizontal plane or inner concave, it is ensured that
It is convenient under clamping only, making occlusion more stable during occlusion.
43 innermost side wall of third occlusal crib is arc-shaped, and third occlusal crib 43 is set on the side wall of upper end 41
Recess 26 is clamped, side wall of the third occlusal crib 43 close to lower end 42 is horizontally or diagonally plane.Third occlusal crib 43 can rise
To the effect identical with the first occlusal crib 24 and the second occlusal crib 25.
In the utility model, provide that single head circle closes tail slide fastener and double end circle closes tail slide fastener.
Wherein single head circle closes tail slide fastener and includes chain tooth 1, above stop 4, stop 2 and tooth chain band down.Wherein above only 4 quantity is 2
It is a, be engaged in the inside of the upper end position of two rooted tooth chain belts respectively, it is lower only 2 quantity be 1, it is described it is lower only 2 be engaged in it is described
Tooth chain band lower end, lower the first occlusal crib 24 stopped on 2 and the second occlusal crib 25 are engaged in the inside of two rooted tooth chain belts respectively.
Double end circle closes tail slide fastener and includes chain tooth 1, stops 2 and tooth chain band down.Only 2 quantity is 2 under wherein, lower only 2 to wrap
First time is included only with second time to stop.In one embodiment, it is only engaged in the lower end of tooth chain band for first time, stops being engaged in for second time
The upper end of tooth chain band realizes that the both ends of tooth chain band are closed at, and is worn on tooth chain band there are two pull head, two pull heads pull open tooth chain
When, slide fastener is in " O " type；In another embodiment, it only abuts only and mutually for second time and is engaged in the middle position of tooth chain band for first time
It puts, when two pull heads pull open tooth chain, slide fastener is in " X " type.
It is provided by the utility model it is upper only 4 and it is lower only 2 be used in combination with above-mentioned semicircle chain tooth 1, upper stop 4 Hes by above-mentioned
Stop down in 2 structure as can be seen that due to it is lower only 2 21 top surface of upper end occlusion portion for arcuate structure, the bottom of lower end occlusion portion 23
Face is horizontal plane or inner concave, and above only 4 41 section of upper end is circular arc, and the bottom surface of lower end 42 is horizontal plane or inclination
Plane；The bottom of the two is for plane, and plane is placed in the inside of tooth chain band in use, and user will not be caused to hinder
Evil increases safety and comfort level.
