Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.
Embodiment
As Figure 1-5, a kind of metal Y type zipper profiles structure, it comprises teeth, described teeth comprise tooth tail 1, tooth tail 22 and tooth head 3, institute's tooth tail 1, tooth tail 22 and tooth head 3 form Y type teeth, described tooth tail 1 is identical with tooth tail 22 structure, and described tooth tail 1 and tooth tail 22 symmetry are connected to tooth head 3, the draw-in groove 4 for connecting non-woven fabrics is formed between described tooth tail 1 and tooth tail 22, the top of described tooth head 3 has one and octagonally strikes out nibs 5, it is described that to strike out nibs 5 wide at the top and narrow at the bottom, the bottom of described tooth head 3 is fixedly installed tooth point 6, described tooth point 6 is positioned at and strikes out immediately below nibs 5, described tooth point 6 comprises tooth point bottom surface 7, tooth point leading flank 8 and tooth point trailing flank 9, described tooth point 6 is from 7s, tooth point bottom surface, the nearly pyramidal structure that tooth point leading flank 8 and tooth point trailing flank 9 extend bottom tooth head 3 in single angle, described tooth point 6 base area is less than tooth head 3, described tooth point leading flank 8 height is higher than tooth point trailing flank 9, the top of described tooth point leading flank 8 is positioned at the middle part of tooth head 3, described tooth point trailing flank 9 is positioned at the bottom of tooth head 3, the side of described tooth head 3 be from top to bottom plane to the transition structure of curved surface.
Described tooth point 6 is apertured to be engaged in another and to coordinate striking out in nibs 5 of practical teeth.Described tooth point 6 bottom surface is octagon.
In this utility model " the single angle " of indication be level and smooth, without bending, according to the meaning of same angular slope.
In this utility model, " plane is to the transition structure of curved surface " of indication refers to that the curved surface 11 of teeth tooth head side in Fig. 1 designs with the smooth connection of the curved surface 11 of teeth tooth head side in Fig. 2, specifically have, the upper side of tooth head 3 is vertical plane structure originally, the downside of tooth head 3 is owing to being connected with tooth point leading flank 8, namely the downside of tooth head 3 is transitioned into curved surface 11, its object is exactly for teeth are when racing angle, when the tooth point 6 of teeth is engaged in and strikes out in nibs 5, have interstitial area 10, therefore extruding can not be produced, doing so avoids the jam phenomenon of slide fastener when corner rapidly.These metal teeth, combine platypelloid type raw material metal punch forming teeth and Y type raw material metal punch forming teeth advantage separately effectively.When teeth are apart from certain state, as shown in Figure 4, curved surface 11 structure designed by teeth, when slide fastener progressively rotates in Y-axis, effectively avoids the protruding parts with teeth tooth point, thus achieves the free corner rapidly of Y-axis in Fig. 4.
The octagon of teeth strikes out nibs 5 structure, has abandoned original loop configuration, and the free activity space that it makes teeth is larger, and has relied on the control of each corner angle when extreme position and unlikely teeth skid off, and makes to realize corner rapidly in the Z-axis direction of teeth.
Tooth point leading flank 8 and tooth point trailing flank 9 single angle design, both ensure that teeth were when punch forming, teeth there will not be to face upward or to the phenomenon of nutation, easily can realize again slide fastener in drawing process is, because be single angle, time under the effect of external force, tooth point 6 freely can slip into octagon and strike out in nibs 5, and in turn ensure that tooth point 6 is freely movable in the shaping punching hole 5 of octagon, thus realize the anxious to corner of X axis in Fig. 5 of slide fastener.
The curve that this utility model adopts and plane transition structure, inside strikes out the single angle forming structure that all adopts of two sides before and after octagon punch forming structure and tooth point 6 that nibs 5 type adopts, jam phenomenon when solving for metal zip fastener drawing under corner state rapidly or open, and the resistance of slide fastener in drawing or when opening compares existing Y type metal zip fastener, resistance is less, and external force pulls feeling better and not easily skidding off of slide fastener.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
