Abstract

The utility model relates to a novel plastic-steel snap fastening device, comprising a base and male snaps which are mutually fixed through pins of male elements. Pins can penetrate through fabric which is arranged between the base and the male snaps, and then the base and the male snaps are fixed on a first fabric part. The pin is provided with a tip and a longitudinal axis which penetrates through the tip. Each tangent line of the periphery of the axial section of the pin is intersected with the longitudinal axis. The same structure is applied to the base and females snaps. The penetrating power of the utility model is improved, and the application area of the plastic-steel snap is expanded.

Description

Novel plastic-steel snap-fastener fixed structure

The utility model relates to mainly the improvement of the plastic-steel snap-fastener of being made by nonmetallic materials, more particularly, relates to a kind of novel plastic-steel snap-fastener fixed structure with improved cloth penetrating device.

Existing pressing closed snap-fastener and made by metal or plastics.Every kind of material all has its pluses and minuses.Metal is pressed and is closed snap-fastener because the stronger penetration power of metal can penetrate and be used for thicker cloth or textile material.Might increase its sense of worth by handling with its plating or with other technology.Intrinsic flexible from the metal that is used for this snap-fastener also might be adjusted the tightness that meshes between the snap-fastener.Yet the shortcoming of the chimeric snap-fastener of metal comprises that plating and most of post processing meeting cause environmental problem.In addition, this cost of copper is higher by smashing used metal, thereby has increased the cost of the snap-fastener of being produced.Although the cost of iron is low relatively, after iron snap-fastener is subjected to inappropriate processing, may get rusty and product quality be had a negative impact.Although metal has stronger penetration power and intrinsic flexible, the metal fatigue of snap-fastener performance appears influencing equally sometimes.

As for the plastics snap-fastener, unless in extreme condition, its color can not fade, and can not get rusty yet, and cost is also low.On the other hand, because the plastics snap-fastener can not penetrate thicker cloth or fabric usually, they seldom are used in the dress-goods in a large number.

The purpose of this utility model provides a kind of new Promethean novel plastic-steel snap-fastener, this snap-fastener has improved fixture, specifically, just provide a kind of novel plastic-steel snap-fastener of the fixture made from plastic-steel with better penetration power, can effectively overcome the nonmetal snap-fastener of prior art and be difficult to be fixed on shortcoming than on the heavy weave, avoid metal snap-fastener cost height simultaneously, may cause the defective of environmental pollution, offered a kind of more useful selection of market and user.

Provide a kind of novel plastic-steel snap-fastener fixed structure according to the utility model, comprise: first base element (102), by first fixture can be fixed to one another with described first base element first joggle piece, wherein, described first fixture and described first joggle piece are integrated into plastics and penetrable mistake is positioned at first fabric portions between described base element and described first joggle piece, thereby described first base element 102 and described first joggle piece are fixed to described first fabric portions, it is characterized in that, described first fixture comprises the first pin spare 106 that has the tip and pass through the longitudinal axis 112 at described tip, each tangent line of the periphery 114 of the axial cross section of the described first pin spare 106 and described longitudinal axis 112 intersects, can make the described first pin spare, 106 pressurizeds after distortion so that described first base element and described first joggle piece are fixed.

The structure that provides according to the utility model, it is characterized in that, comprise each other by second fixture fixing second base and second joggle piece, described second fixture and described second joggle piece plastic-steel integrated molding, thereby penetrable mistake second fabric portions of described second fixture is fixed to described second fabric portions with described second base element and described second joggle piece, described second fixture comprises the second pin spare that has the tip and pass through the longitudinal axis at described tip, each tangent line of the periphery of the axial cross section of the described second pin spare and described longitudinal axis intersect, and the described second pin spare distortion that can make described second fixture is to fasten described second base element and described second joggle piece.

Wherein, described first base element 102 comprise one can be by the through hole 110 of the described first fixture pin, described through hole 110 is little near the part aperture of first joggle pieces, and is big away from the part aperture of first joggle piece, to avoid fabric and forms wrinkle.Described first joggle piece is evenly to be provided with a plurality of anti-skidding prominent grains 116 on the pin thread and the first base element adjacent surface around axle 112; Described first base element and the first joggle piece adjacent surface are provided with boss.

Implement the novel plastic-steel snap fasteners that the utility model provides, with the plastic-steel is material, with simple structural design, improved greatly that the plastic-steel snap-fastener is fixed or the penetration power when installing than heavy weave, both avoid metal snap-fastener higher cost and possible pollution, enlarged the scope of application of plastic-steel snap-fastener again.
