Abstract

The utility model discloses a puller of a double-face toothed zipper, which aims at providing the puller of the double-face toothed zipper, which is featured with good anti-theft property, long service life, high strength, easiness for opening and closing in use and accuracy for closing teeth. The puller comprises an upper protective plate, a lower protective plate and a guide base core which is connected between the upper protective plate and the lower protective plate; an internal space allowing a double-layer sprocket zipper to be accommodated is formed between the upper protective plate and the lower protective plate; and a connecting part allowing a pull piece to be mounted is arranged above the upper protective plate; and the puller is characterized in that a tongue-shaped balancing guide piece is arranged on the guide base core. According to the utility model, left chain teeth and right chain teeth at the upper and lower layers are more stably engaged with each other when buckled together without left and right loosening in a transverse direction; and the tongue-shaped balancing guide piece has a guiding and isolating effect on buckling or separation of the chain teeth at the upper and lower layers without misalignment, so that the chain teeth at the upper and lower layers can be smoothly buckled with each other.

Description

The pull head of double cog slide fastener

Technical field

The utility model relates to slide fastener, more specifically to a kind of pull head of double cog slide fastener.

Background technology

Nylon zipper range of application in ready-made clothes, case and bag and miscellaneous processing is extremely wide; Along with growing up to and competition of economic activity; The user requires more and more to relevance grade, the specific function of slide fastener; Therefore the general traditional practice can not meet client's specific (special) requirements, for example: the lifting of intensity, the anti-sudden and violent tooth that breaks, waterproof, fungi-proofing, safety, environmental protection etc.; And all belonging to the single cog structure through looking into general nylon zipper, down and mat is sewed up to link together and formed, this is the technology of dealer's convention widely at last, strap for sprocket; The convention patent Taiwan Announcement Number No. 441257 (improvement of nylon zipper band) of prior art is to be the double cog structure in addition; Because slide fastener has two-layer up and down; Slide fastener close tooth the time cause about, the instability of sprocket position, the left and right sides makes and can not steadily close tooth; Usually cause one side can close the disappearance that tooth, another side are sudden and violent tooth, draw sliding unusual especially at the bent face place easily.

The utility model content

The purpose of the utility model provides that a kind of theftproof performance is good, long service life, intensity are high, during use folding light, close the tooth pull head of double cog slide fastener accurately.

In order to reach above-mentioned requirements; The technical scheme of the utility model is: it include upper guard board, down backplate and connect this upper guard board and following backplate between the guiding base heart; Form the inner space that holds double-deck sprocket slide fastener between this upper guard board and the following backplate; Above upper guard board, be provided with the connecting portion that supplies the installing pulling-on piece, it is characterized in that being provided with in the heart the balance guide card of a ligule at the guiding base.

On described balance guide card, be shaped on several guide grooves that match in the tooth head of sprocket.

Pull head according to the double cog slide fastener of technique scheme design; Interlock was more firm when two-layer left sprocket and right sprocket snapped together about making; Can not appear laterally left and right loosening; The balance guide card of ligule plays guiding and buffer action to bilevel sprocket when fastening or separate, can not misplace, and making up and down, two-layer sprocket can fasten smoothly.

The specific embodiment

Below in conjunction with accompanying drawing and through embodiment the utility model is done further to describe.

Fig. 1 to Fig. 4 is the structural representation of the pull head of double cog slide fastener.From figure, find out it include upper guard board 1, down backplate 2 and connect this upper guard board 1 and following backplate 2 between the guiding base heart 3; Form the inner space 5 that holds double-deck sprocket slide fastener 4 between this upper guard board 1 and the following backplate 2; Above upper guard board 1, be provided with the connecting portion 6 that supplies the installing pulling-on piece; On the basic heart 3 of guiding, be provided with the balance guide card 7 of a ligule, be shaped on 4 guide grooves 8 that match with double-deck sprocket slide fastener 4 sprocket tooth heads on this balance guide card 7.Certainly, on this balance guide card 7, also can not make guide groove 8, its structure such as Fig. 5, shown in Figure 6.To bilevel sprocket when fastening or separate, play guiding and buffer action as shown in Figure 7.

Claims
