Abstract

The utility model relates to a zipper. The zipper comprises a first zipper band, a second zipper band, an upper stopper, a lower stopper, a plurality of first zipper teeth, a plurality of second zipper teeth and zipper slide heads. The lower portion of a tooth root of each first zipper tooth and the lower portion of a tooth root of each second zipper tooth are respectively connected with a zipper head guide slide block, wherein the tooth roots and the zipper head guide slide blocks form upper steps and lower steps. The zipper head guide slide blocks are arranged on the first zipper band and the second zipper band, so that the zipper slide heads are made to be not in contact with the first zipper band the second zipper band, the zipper slide heads pass through the space between the first zipper teeth and the second zipper teeth along the zipper head guide slide blocks, and therefore the first zipper teeth and the second zipper teeth are engaged or disengaged. The zipper is simple in structure, high in practicability and convenient to use. When used, the zipper can well keep the direction, pulling of a puller is smooth, and the phenomenon of blockage is completely avoided.

Description

A kind of slide fastener

Technical field

The utility model relates to a kind of slide fastener, relates in particular to a kind of slide fastener with slider of zipper fastener rail plate.

Background technology

Slide fastener is to rely on continuously arranged chain tooth, and the connector that makes article and close or separate is existing in a large number for clothes, bag, tent etc.Along with people's life requirement improves constantly, except its folding function, also can start to consider other aspects, as its convenience, practicality etc. to the demand of slide fastener.But, slide fastener of the prior art, pull head clamps two side chain teeth, by drawing button loop to slide, realizes the chain tooth of both sides intermeshing or throw off., there is the ill problem of folding in the slide fastener of this structure.Because pull head touches two side chain bands, when folding slide fastener, pull head easily bites line segment or cloth and that pull head is drawn is motionless, if pull by force pull head, can more sting darker.And in the process that pulls pull head, slide fastener is easily distorted, also can cause blocked portion phenomenon.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and a kind of slide fastener with slider of zipper fastener rail plate is provided, and slider of zipper fastener slides by slider of zipper fastener rail plate, avoids contacting with the chain band on both sides.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of slide fastener, comprising: one first chain band, one second chain band, upper only, lower only, multiple the first sprocket, multiple the second sprocket, zipper slide head; Described the first chain space of teeth is located on the first chain band, and each first sprocket comprises sprocket and first time sprocket on corresponding first, and sprocket is distinguished the upper surface of interlock the first chain band and the lower surface of the first chain band with the tooth root of first time sprocket on first; Described the second chain space of teeth is located on the second chain band, and each second sprocket comprises sprocket and second time sprocket on corresponding second, and sprocket is distinguished the upper surface of interlock the second chain band and the lower surface of the second chain band with the tooth root of second time sprocket on second; The tooth root bottom of described the first sprocket and the second sprocket is connected respectively a slider of zipper fastener slider guide, described tooth root and slider of zipper fastener slider guide form up/down steps, slider of zipper fastener slider guide be located at respectively on the first chain band and the second chain band on, make described zipper slide head not contact the first chain band and the second chain band, through the first sprocket and the second sprocket, make its mutual interlock or separation along slider of zipper fastener slider guide.

Preferably, the quantity of described zipper slide head is two, and the first sprocket can be separated or interlock from the two ends of slide fastener respectively with the second sprocket.

Preferably, the half that the thickness of described slider of zipper fastener slider guide is thickness at root of tooth, its width equals the width of tooth root.

Preferably, described chain band for weaving cotton cloth, macromolecular material or composite.

Preferably, described zipper slide head, the first sprocket, the second sprocket are that plastics or metal are made.

beneficial effect

Compared with prior art, the utility model the utility model is simple in structure, practical, easy to use, and slide fastener in use can keep direction preferably, and pull head slides smooth and easy, avoids group card phenomenon completely.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is cutaway view of the present utility model;

Fig. 3 is the cutaway view of the utility model the second sprocket and the second chain band.

Detailed description of the invention

For making that architectural feature of the present utility model and effect of reaching are had a better understanding and awareness, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:

Referring to Fig. 1 to Fig. 2, as shown in the figure, slide fastener shown in figure comprise one first chain band 1, one second chain band 2, upper only, lower only, multiple the first sprocket 3, multiple the second sprocket 4, upper zipper slide 5, lower slide fastener slide head 6, multiple slider of zipper fastener slider guide 7.

Described the first sprocket 3 intervals are located on the first chain band 1, and each first sprocket 3 comprises on corresponding first sprocket on sprocket 31 and first time sprocket 32, the first and distinguishes the upper surface of interlock the first chain bands 1 and the lower surface of the first chain band 1 with the tooth root 33 of first time sprocket.Described chain band can be for weaving cotton cloth, macromolecular material or composite.

Described the second sprocket 4 intervals are located on the second chain band 2, and each second sprocket 4 comprises on corresponding second sprocket on sprocket 41 and second time sprocket 42, the second and distinguishes the upper surface of interlock the second chain bands 2 and the lower surface of the second chain band 2 with the tooth root 43 of second time sprocket.

Tooth root 33 bottoms of described the first sprocket, tooth root 43 bottoms of the second sprocket and on bottom stopper, be connected respectively slider of zipper fastener slider guide 7, described tooth root and slider of zipper fastener slider guide 7 form up/down steps, slider of zipper fastener slider guide 7 be located at respectively on the first chain band 1 and the second chain band 2 on, make upper and lower zipper slide head not contact the first chain band 1 and the second chain band 2, respectively along slider of zipper fastener slider guide 7 through the first sprocket 3 and the second sprocket 4, make its mutual interlock or separation.The thickness of slider of zipper fastener slider guide 7 is the half of thickness at root of tooth, and its width equals the width of tooth root.In fact, slider of zipper fastener slider guide 7 can be and is wholely set with tooth root, can be that plastics are made, as resin.Multiple slider of zipper fastener slider guides 7 are uniformly distributed, and form upper and lower four " slider of zipper fastener rail plates ", and slider of zipper fastener slides smoothly on above-mentioned guide rail.

More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
