Top surface is equipped with pull-rod installation position, and second pull head includes the second upper flange of the second upper flange, the second lower wing plate and connection, the
Second chain column of two lower wing plates, is located by connecting in the first pull head axial direction between the first chain column and the second chain column, and described
Between one lower wing plate one end corresponding with the first chain column and the second lower wing plate by pin shaft be pivotally connected, first lower wing plate it is another
End offers a stretch cord perforation.
Preferably, first pull head is YG head, and the front and rear sides of the pull-rod installation position further respectively have elastic slice slot position.
Further, the first chain column side opposite with the second chain column is equipped with a positioning protrusion, and described the
The corresponding side of two chain columns offers a positioning groove compatible with the positioning protrusion.
Further, first lower wing plate lower end surface is equipped at intervals with a plurality of first pivoted holes, the second lower wing plate lower end
Face interval is equipped with a plurality of second pivoted holes, interval of the first pivoted hole interlaced arrangement in second pivoted hole, institute
Stating pin shaft and being plugged in first pivoted hole and the second pivoted hole connects first pull head and the second pull head.
Further, the front end of first upper flange extend outwardly set there are two connect boss, second upper flange
Lower end surface be correspondingly provided with two recessing grooves compatible with the connection boss.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point: the double-make pull header structure is made of two pull head pin shaft linkings, and the chain column of two pull heads is located by connecting, and makes
Two pull heads will not be swung in the up-down direction, meanwhile, the first lower wing plate bottom surface of the first pull head is perforated equipped with stretch cord, is used for
Fixed stretch cord, stretch cord play telescopic action in pull head drawing.Therefore double closure pull heads of the utility model, solve single drawing
The double closures of head have that the more tight card of sense, drawing have some setbacks, and extend the service life of zipper, and the utility model is double
It is small in size to be closed pull head, when plating is not easy peeling blistering.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.For comprehensive understanding the utility model, below
Many details are described to, but to those skilled in the art, can also realize the utility model without these details.For public affairs
Component, method and the process known, are not described in detail below.
A kind of double-make pull header structure, referring to figs. 1 to Fig. 4, including the first pull head 10 interconnected and the second pull head
20, the inner-cavity structure of the first pull head 10 and the second pull head 20 is identical as specification, but shape is different.It is certain special on clothes to meet
The use demand at position, the first pull head 10 preferably use YG head, which includes the first upper flange 11, the first lower wing plate
12 and the first upper flange 11 of connection, the first lower wing plate 12 the first chain column 13, the top surface of first upper flange 11, which is equipped with, draws
Stick installation position 14, the front and rear sides in 14 axial direction of pull-rod installation position further respectively have elastic slice slot position 15, and elastic slice slot position 15 is for putting
