CN2245367Y - Polyvinyl chloride slide fastener with different colour - Google Patents

Abstract

The utility model relates to a polyvinyl chloride slide fastener with different colors, which is composed of two slide fastener sheets and a slide fastener head. Two entrances of the slide fastener head have the same width, and short flanges with inward folding of 90 DGE are arranged on both side walls of the slide fastener head from the entrance of the front end to the bottom of an exist of the back end. The short flanges are opposite to tear-drop flanges at the bottom of a middle partition sheet. An extruding track is arranged on the middle part of the slide fastener head, and the width of the extruding track is equal to the butting thickness of a male clamping edge and a female clamping edge of the two slide fastener sheets. One slide fastener piece has the appearance with different colors on the clamp edges, and thus the slide fastener sheet can be distinguished from the other slide fastener sheet. The utility model can be rapidly assembled without fault.

Description

Polyvinyl chloride is inserted the salad chain

The utility model relates to a kind of slide fastener, and particularly a kind of slide fastener assembling speed that makes improves, and the slide fastener of the forming polyvinyl chloride that slider of zipper fastener can not deviate from easily under the exertin operation is inserted the salad chain.

The polyvinyl chloride zipper of habit formula, as Fig. 5, shown in 6, its male and female two slide fastener sheets 911,912 clamping edge is all homochromy and can't differentiate, so that have often with public in assembling, situation with female misloading occurs, add that its end outlet 923 places, slider of zipper fastener 92 slide fastener aisle are provided with the extruding road 925 of overvoltage, so these extruding road 925 overvoltages by name, reason is width design ratio two slide fastener sheets 911 herein, 912 public affairs, it is also narrower that master card connects the thickness of the normal butt joint of edge, so two slide fastener sheets 911,912 are dragged through herein the time, surely can be subjected to special extruding, strength and be the butt joint shape; But this extruding result often makes misloading with public, crowded bad under exertin with the clamping edge of female slide fastener sheet 911 or 912, consequently can't heavily tear group open again and cause waste.Slider of zipper fastener 92 is for cooperating the not male and female clamping edge of uniform thickness of two slide fastener sheets, 911,912 tops in addition, so be divided into two anisometric imports 922,922 ' with shim 921, and the slider of zipper fastener 2 bottoms only lower end of shim 921 and a sidewall 924 are provided with bead 9211,9241, be to produce not wide track, make two slide fastener sheets 911,912 enter unbalance stress, can present and drag backward phenomenon on one side; Slide fastener aisle and rear exit 923 do not have relative configurations because 9211,9241 of beads are located at position, the place ahead yet simultaneously, have more caused slide fastener finished product slider of zipper fastener 92 easy squints under stressed big situation to deviate from, and not applying to use influences ordinary life.

The purpose of this utility model is providing a kind of male and female limit to recognize that easy, group 121 causes damage, also can pull down the unlikely waste of reorganization.Moreover also because whole slider of zipper fastener 2 bottoms are provided with the short bead 241,241 ' of teardrop shaped bead 211 and both sides, so make the male and female clamping edge 111,121 of slide fastener sheet 11,12 can be limited in unlikely outer taking off out in the slide fastener aisle fully.

The utility model embodiment in conjunction with the accompanying drawings is described in further detail as follows:

Graphic explanation:

Fig. 2 is a decomposing schematic representation of the present utility model.

Fig. 3 is the schematic diagram of the utility model assembling.

Fig. 4 implements illustration for the utility model operation.

Fig. 5 A-5D is the schematic diagram of habit formula structure.

Fig. 6 is that illustration is implemented in the operation of habit formula structure.

As shown in Figure 1, 2, the utility model polyvinyl chloride is inserted the salad chain, and mainly include two slide fastener sheets 11,12 and a slider of zipper fastener 2 and form, wherein:

Two slide fastener sheets 11,12 are to be penetrated by plastics to form, and its upper end is respectively equipped with wavy male and female clamping edge 111,121, and wherein the master card on the slide fastener sheet 12 connects edge 121 operating surfaces, when producing, mix with not homochromy grain, make tool insert look 122, promptly be can with the color of slide fastener sheet 11 resolutions.

One slider of zipper fastener 2, roughly front end is blunt pointed swelling and then holds "  " font body that contracts level with both hands, and lower end, blunt sharp position is provided with a shim 21, front end is swollen partly be divided into two imports 22,22 '; The setting that shim 21 lower ends are set as down the teardrop shaped bead 211 of " T " and shim 21 is the rough length of tool only, so make slider of zipper fastener 2 tail ends be single outlet 23, wherein all to be provided with 90 ° of dresses of invagination from two side 24,24 ' bottom that front end import 22,22 ' extends to back outlet 23 rapidly convenient because of slider of zipper fastener 2 again, and the polyvinyl chloride of the finished product slider of zipper fastener difficult drop-off of forming is inserted the salad chain.

The technical solution of the utility model is:

A kind of polyvinyl chloride is inserted the salad chain, is made up of two slide fastener sheets and a slider of zipper fastener; Wherein:

By two slide fastener sheets of plastics injection molding, its upper end is respectively equipped with wavy male and female clamping edge;

This slider of zipper fastener, front end are blunt pointed swelling and then hold the  font body that contracts level with both hands, and blunt sharp position has a shim makes front end be divided into two imports, and the rear end is single outlet; The lower end of shim is the lacrimal bead of inverted T-shaped, is provided with an extruding road after the shim; It is characterized in that: two imports of slider of zipper fastener are wide, the two side extends to the short bead that the back outlet bottom all is provided with 90 ° of invaginations from the front end import, it is impartial that relative formed track with the teardrop shaped bead under the shim also is, and above-mentioned extruding road width is the thickness that equals the butt joint of male and female clamping edge; Has the slotting look of distinguishing with another sheet on the clamping edge operating surface one of in the above-mentioned two polyvinyl chloride slide fastener sheets.

Effect of the present utility model is:

Please refer to shown in Fig. 3,4, by means of the different slotting look 122 that has on the slide fastener sheet 12, so slide fastener sheet 11,12 male and female limits can be distinguished easily during assembling, it is also impartial to add that the wide import of slider of zipper fastener 2 22,22 ' design produce track, the slide fastener sheet is entered very smooth and easyly not have and drag phenomenon and produce, so assembling speed can obviously improve, and can reduce the generation of defective products.The above-mentioned in addition suitable wide extruding road 25 of being located at slider of zipper fastener 2 in fact is with the slide fastener aisle junction behind the shim 21, be designed to just supply slide fastener sheet 11,12 male and female clamping edge 111,121 width that engage can and needn't be narrow, slide fastener sheet 11 like this, 12 if having with public, occur with female misloading mode, but because of there being this suitable wide design unlikely by excessive compression, so can be to the public affairs of misloading, master card connects edge 111, short bead 241,241 ' is relative with the teardrop shaped bead 211 under the shim 21, make the track equalization of institute's shape, slide fastener sheet 11,12 enter the back forward advances and can pool one joint in the suitable wide extruding road 25 of slider of zipper fastener 2, oppositely then cuts to dial through shim 21 and separates.
