Abstract
A tooth structure of zipper is composed of tooth top, tooth root with a slot for embedding the zipper belt in it, and tooth neck between tooth top and tooth root. It features that the both edges of said slot on tooth root are extended out to form two belt-protecting basses, which can isolate zipper slider from zipper belt and prevent other things from coming in the slider.
Description
Technical field
The invention belongs to the annex of slide fastener, be specifically related to a kind of chain teeth structure of slide fastener.
Background technology
Be arranged on the chain tooth of two chain belt edge, its free end can be meshing with each other under the effect of zipper slide head, realizes the most basic opening and closing function of slide fastener.The process that realizes this function has such details usually: along with the slip of zipper slide head, vertically be arranged in chain tooth on the chain belt edge respectively because of being subjected to the restriction of slide fastener slide head inner chamber dwell angle shape, thereby its tooth root portion is subjected to the mutual well-regulated engagement of pushing of a zipper slide two side.
The chain tooth of known technology is finished in the process of opening and closing action at the zipper slide head, the chain belt of chain tooth heel is subject to the friction of a zipper slide sidewall crushing block, wearing and tearing, scratch phenomenon appear in regular meeting, thereby reduce the chain band strength, and then influence service life of whole piece slide fastener, especially be at the whole piece slide fastener and do opening and closing operations under the out-of-flatness state, the zipper slide head to the injury of chain belt with even more serious; In addition, chain band edge and other foreign matter easily enter zipper head head inside from the sidewall centre joint of zipper slide head, and influence the light slippery of zipper slide head, also can stuck zipper slide head when serious, slide fastener is damaged.
Summary of the invention
For overcoming slide fastener above shortcomings in the prior art, the present invention aims to provide a kind of chain teeth structure of slide fastener, the slide fastener of making according to this chain teeth structure, the sidewall crushing block and the chain belt of zipper slide head are isolation, therefore, fundamentally stopped chain belt phenomenon easy to wear, abrasive, slide fastener is greatly prolonged service life.
For achieving the above object, the present invention has adopted following technical scheme: the chain teeth structure of this slide fastener has comprised the tooth top of engagement, and is used for the tooth root of fixedlying connected with chain belt, forms integral body by the transition of tooth shoulder between tooth top and the tooth root; The tooth root middle part is provided with band muscle groove, the chain trough of belt of admitting chain belt, and the chain trough of belt is characterized in that towards tooth root endwall opening: in the both sides of tooth root endwall chain belt notch edge, the cell wall of chain trough of belt has formed two chain belts towards opening direction extension back at this and has protected platform.
During concrete enforcement, chain belt protects platform thickness to being provided with the chain belt locating hole.
Beneficial effect: the also last heel of meeting at chain tooth root is provided with any report and the information that chain belt protects platform in the known technology before the present invention makes.Chain belt is set to be protected and has reached three effects behind the platform at least: at first, make between zipper slide head and the chain belt and keep apart, chain belt protects the platform outer surface and as the slideway of zipper slide centre joint top, low wall the slide fastener chain belt is effectively protected, avoided the wear phenomenon of zipper slide head, also can not injure chain belt on irregular slide fastener even the zipper slide head moves to chain belt; Secondly, the design that chain belt protects platform make the centre joint of zipper slide head and chain belt protect interstation remain one constant and be very little fit clearance, can prevent effectively that like this zipper slide head zipper strip, selvedge or other foreign matter in drawing process from snapping in the zipper slide head, to avoid the light slippery of slide fastener to descend even to destroy slide fastener.This design has solved for a long time, and the zipper slide head easily causes wearing and tearing and influences the slide fastener problem in service life of using chain belt.Moreover, after increasing chain belt and protecting platform, further improved the intensity of slide fastener, make the outward appearance of slide fastener seem more rough, atmosphere simultaneously.
Description of drawings
Fig. 1 is the perspective view of one embodiment of the invention;
Fig. 2 is an application examples of chain tooth of the present invention, cross section structure figure that the zipper strip behind band muscle, the chain belt has been installed shown in the figure;
Fig. 3 is the vertical view of Fig. 2, the structure that this figure only draws three chain teeth.
The specific embodiment
Referring to Fig. 1, and in conjunction with Fig. 2, Fig. 3, sequence number is represented respectively among the figure: tooth top 1, tooth root 2, chain belt protect platform 3, tooth root endwall 4, chain belt locating hole 5, chain belt locating slot 6, band muscle locating slot 7, tooth shoulder boss 8, tooth shoulder 9, tooth top groove 10, chain belt 11, band muscle 12.
Fig. 1 shows the stereochemical structure situation of one embodiment of the invention.The chain teeth structure of this slide fastener has comprised the tooth top 1 of engagement, and is used to admit the fixedly connected tooth root 2 of band muscle 12, chain belt 11, takes on 9 transition by tooth between tooth top 1 and the tooth root 2 and forms single piece.The middle part of tooth root 2 is provided with the locating slot of admitting band muscle 12, chain belt 11.The locating slot opening is made of chain belt locating slot 6 that is interconnected and band muscle locating slot 7 on tooth root endwall 4, and band muscle 12 and chain belt 11 are single piece.Chain belt protects platform 3 and constitutes whole with the whole chain tooth, one-shot forming during injection moulding (can certainly be adopted material making such as metal, become the metal zip fastener annex), chain belt protects platform 3 can regard two retaining walls that the two side of chain belt locating slot 6 forms to the opening direction extension respectively as, and chain belt 11 is between these two upper and lower retaining walls.Therefore, a during use and zipper slide two side of chain tooth coupling is bumped less than chain belt when pushing away tooth root endwall 4 squeezing, and just slides on chain belt protects two surfaces of platform 3, has reached the purpose of the chain belt that can not wear and tear.
Chain belt locating hole 5 is fabrication holes, plays the effect of stationary positioned chain belt, establish with do not establish, hole count decided by feelings.Chain belt protects the thickness of platform 3 can be decided according to a zipper slide two side centre joint height, that is to say that two chain belts protect the thickness that platform 3 adds chain belt 11 should be more smaller than a zipper slide two side centre joint height, and that its width does not need is very wide, as long as slightly narrower, get final product to guarantee that a zipper slide two side is slided thereon than tooth root endwall 4.
Claims (2)
