Summary of the invention
The object of this invention is to provide that a kind of theftproof performance is good, long service life, bonding strength are high, using when turning also can the pull head of light a kind of zipper with double layer of teeth of folding.
The technical scheme adopted in order to the pull head reaching above-mentioned requirements zipper with double layer of teeth is: it includes upper guard board and lower backplate, upper side guard board and lower side guard plate is provided with respectively in the both sides of upper guard board and lower backplate, connected by the base heart between upper guard board and lower backplate, the ligulate guide card separated by upper and lower two-layer slide fastener is designed with in the heart at base, it is characterized in that the distance inside contracting one deck transverse tooth thickness degree in the lower backplate rear end of nearly Ji Xinchu than upper guard board, and the fillet with lower backplate is also remained with in the both sides of retracted position, base heart rear end, intensity is opened with the anti-tensile strengthened between upper guard board and lower backplate.
Under the upper side guard board ratio of base heart one end, side guard plate is long.
The upper guard board of nearly Ji Xinchu and the inner surface of lower backplate rear end are all shaped with and guide sprocket to enter pull head or leave the groove of pull head.
The width at described access recess place is the width of sprocket, and the degree of depth of described groove is the thickness of 1/4-1/8 one deck tooth.
According to the pull head of a kind of zipper with double layer of teeth that such scheme manufactures, due to inside contracting of lower side guard plate, the internal layer slide fastener when turning is made to have enough bending position, make when folding tooth, pull head can more smoothly slide, and it is less than drawing general zipper with double layer of teeth frictional resistance, pull more easily smooth, the position of closing tooth is more accurate, and slide fastener and begin chain wear and tear less, longer service life.Also remain with the fillet with lower backplate in the both sides of base heart rear end simultaneously, the anti-tensile added between the bonding strength of lower backplate and the base heart and upper and lower backplate opens intensity, and when the slide fastener that pull head folding is turned, the chain band on both sides is made to abut against the side of two fillets, play spacing effect, make the angle being conducive to entering pull head conjunction tooth that slide fastener keeps stable.
