Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, fig. 1 is a schematic view of an overall structure of an embodiment of the present invention; FIG. 2 is a schematic view of the structure of the single-side cloth belt and the tooth shown in FIG. 1; FIG. 3 is a top view of the single-side cloth belt and tooth structure shown in FIG. 2; FIG. 4 is a side cross-sectional view of the tooth shown in FIG. 1; FIG. 5 is a rear view of the tape shown in FIG. 1; fig. 6 is a rear view of the tooth shown in fig. 1.

The utility model provides an among the concrete implementation mode, mainly include two strap 1 and set up tooth 3 on each strap 1, tooth 3 is the interval setting along the length direction at strap 1 edge, and tooth main part 305 side reason and the vertical direction of tooth 3 are equipped with first angle of deflection, and tooth basal portion 306 side reason and the vertical direction of tooth 3 are equipped with the second angle of deflection.

The tooth base 306 is connected with the cloth tape 1 so that the cloth tape 1 and the teeth 3 form a basic structure of the zipper, a second deflection angle structure is arranged between the side edge of the tooth base 306 of the teeth 3 and the vertical direction, the second deflection angle structure can ensure that the tooth base 306 is stably connected with the cloth tape 1 and simultaneously reduces the whole size of the tooth base 306 of the teeth 3, a first deflection angle is arranged between the side edge of the tooth main body portion 305 of the teeth 3 and the vertical direction, and the first deflection angle is used for reducing the size of the tooth main body portion 305 so that the whole structure of the zipper is reduced.

Specifically, install tooth base 306 and strap 1 of tooth 3 in order to form the zip fastener, when using, because tooth base 306 side edge and the vertical direction of tooth 3 are equipped with the second angle of deflection structure, the second angle of deflection can guarantee that tooth base 306 and strap 1 are connected the whole size of tooth base 306 of tooth 3 when stable, because again because tooth main part 305 side edge and the vertical direction of tooth 3 are equipped with first angle of deflection, first angle of deflection is used for reducing the size of tooth main part 305 so that zip fastener overall structure, when people use the zip fastener structure disclosed in this application, the physical strength of zip fastener has been guaranteed in tooth base 306 and the connection of strap 1, and first angle of deflection and second angle of deflection make the zip fastener structure littleer, make tooth 3 seem more small and exquisite, be more suitable for the supporting use of frivolous style clothing.

In order to ensure that the teeth 3 are connected with the cloth belt 1 more stably and the zipper has higher use strength, the edge of the cloth belt 1 is provided with a band part 2, the tooth base part 306 is provided with a mounting groove matched with the band part 2, and the band part 2 is a cylinder; tooth 3 cooperates the erection joint through tooth basal portion 306's mounting groove and cylinder lacing bar portion 2, and simultaneously, the opening part of mounting groove is less than the diameter of lacing bar portion 2 and the same with strap 1's thickness, can strengthen tooth basal portion 306 mounting groove and lacing bar portion 2's joint strength, guarantees the use physical strength of zip fastener.

Further, the head portion 304 of the tooth 3 is of a spindle-shaped structure, and the neck portion 302 of the tooth 3 is of an inward concave arc-shaped structure; the tooth head part 304 is provided with a tooth head concave part 301, and the tooth base part 306 is provided with a tooth convex part 303 which is in clamping fit with the tooth head concave part 301; under the zip fastener closed state, tooth head 304 agrees with each other with the tooth neck 302 of adjacent tooth 3, and tooth bulge 30 agrees with the assembly with the concave scarce portion 301 of tooth head of adjacent tooth 3, realizes tooth 3 interlock each other in vertical, the horizontal direction to can bear certain external force, increase the interlock intensity of zip fastener tooth 3, make zip fastener both sides tooth 3 be difficult to part.

It should be noted that the tooth protrusions 303 are symmetrically arranged on the tooth base 306; when people use the zipper, the teeth 3 can be subjected to impact force of die opening and die casting, and the teeth protruding parts 303 are symmetrically arranged on the teeth base parts 306, so that the pulling force impact force applied to the teeth 3 is more uniform, and the teeth 3 are ensured to be meshed stably and the service time of the teeth 3 is longer.

Further, the width of the tooth base portion 306 is larger than the width of the tooth main body portion 305; the tooth base 306 is arranged at the joint of the tooth main body part 305 and the ribbed part 2, the tooth base 306 is wider than the tooth main body part 305 as a whole and has a step-shaped structure, and the bonding force between the tooth 3 and the cloth tape 1 is enhanced because the contact surface between the tooth base 306 and the cloth tape 1 is larger than that between the tooth main body part 305 and the cloth tape 1.

Finally, it is also to be noted that the first deflection angle is larger than the second deflection angle; the tooth base 306 keeps a normal demoulding angle, so that normal mould opening and die casting of the tooth 3 are not affected, the first deflection angle is increased, the area of the upper surface of the tooth main body 305 is reduced under the condition that the area of the bottom of the tooth main body 305 is not changed, and the tooth 3 is thinner, smaller and thinner in visual effect and more suitable for light and thin clothes styles; the setting of step portion, the area of contact of tooth basal portion 306 and strap 1 increases, strengthens the cohesion of tooth 3 to avoided the zip fastener physics powerful low, the problem of the tooth easily appears falling.

In summary, the plastic steel zipper provided by the embodiment mainly comprises two cloth belts and teeth arranged on the cloth belts, wherein the teeth are arranged at intervals along the length direction of the edges of the cloth belts, a first deflection angle is arranged between the side edge of the tooth main body part of the teeth and the vertical direction, and a second deflection angle is arranged between the side edge of the tooth base part of the teeth and the vertical direction; install the tooth basal portion and the strap of tooth in order to form the zip fastener, when using, because tooth basal portion side edge and the vertical direction of tooth are equipped with second angle of deflection structure, the second angle of deflection can guarantee that tooth basal portion and strap are connected the whole size of the tooth basal portion of tooth when stable, again because tooth lateral portion and the vertical direction of tooth are equipped with first angle of deflection, first angle of deflection is used for reducing the size of tooth main portion so that zip fastener overall structure, when people use the zip fastener structure disclosed in this application, the physical strength of zip fastener has been guaranteed in being connected of tooth basal portion and strap, and first angle of deflection and second angle of deflection make the zip fastener structure littleer, make tooth seem more small and exquisite, be more suitable for the supporting use of frivolous style clothing.
