Abstract
The utility model relates to a zipper with a novel structure, which comprises a pair of cloth strips which are provided with a plurality of zipper teeth and a zipper head which can be arranged on the zipper teeth in a slide mode. The utility model is characterized in that each zipper tooth comprises a basal body and a wedge head which is arranged on the front end of the basal body, wherein two side walls of the wedge heads are respectively provided with the wedge-shaped zipper teeth; the positions of the back sides of the wedge-shaped zipper teeth which are arranged on the two side walls of the wedge heads are provided with grooves of concave cavities which are surrounded together with the wedge-shaped zipper teeth and can be embedded by the zipper teeth of the corresponding side. Each corresponding zipper tooth of the two cloth strips is embedded into the concave cavities of the corresponding side for sealing by the mutually nesting of the wedge heads and the wedge-shaped zipper teeth, and the zipper teeth can be reliably and mutually inserted together. Thereby, the reliability of the embedding of each zipper tooth can be ensured effectively and the volume of the mesh ends of the zipper teeth can be effectively reduced to a minimum. Gaps among the zipper teeth can be controlled in a minimum range, and the good sealing performance among the zipper teeth can be ensured. The utility model has the advantage of good flexibility, and can not generate curling phenomenon.
Description
Technical field
The utility model relates to slide fastener a kind of slide fastener, particularly a kind of novel structure, good seal performance, link robust.
Background technology
Existing slide fastener mainly contains two kinds of metal zip fastener and nylon zippers, and it mainly is made up of the strap of chain tooth and the slider of zipper fastener that slides on the chain tooth a pair of device.The difference of this slide fastener of two types is mainly reflected in the difference on the manufactured materials of chain tooth: a kind of is the chain tooth that adopts metal material processing to form, and another kind is the chain tooth that adopts the nylon plastic material to process.Yet, the slide fastener of the chain tooth that present common employing nylon plastic material processes, end of engagement generally is processed into the slightly plush copper of oval in shape between its chain tooth.Thereby, make big, the poor sealing performance in slit that comes out processing and manufacturing slide fastener exists the chain tooth it to be applied in problems such as influencing the warming of clothing performance on the clothing.And the slide fastener of the chain tooth that the employing metal material processing forms, protruding hook is processed in one side of the end of engagement between its chain tooth, another opposite side be processed into accordingly can ccontaining protruding hook cavity, being meshing with each other between its chain tooth exactly to embed in the cavity of another chain tooth opposite sides by the protruding hook of a chain tooth wherein is meshed together two straps of slide fastener.Because the slide fastener of this structure is processed into a side of its end of engagement protruding hook-shaped, another side processing cavity shape, must cause the volume of whole chain tooth bigger, thereby, make the metal zip fastener of this structure not only exist big, the poor sealing performance in slit of chain tooth equally, difficulty of processing is big, production cost is high, and it is applied in problems such as certainly will influencing the warming of clothing performance on the clothing; But also exist interaction and pliability is all relatively poor, and be easy to generate dislocation between the chain tooth, be applied in and be easy to generate curling problems such as phenomenon on the clothing.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing problems, provide a kind of novel structure, good seal performance, link robust, interaction is good and pliability is good slide fastener.
The technical solution of the utility model is achieved in that
A kind of slide fastener of novel structure, comprise that a pair of device has the strap of some chain teeth to reach the slider of zipper fastener that is installed on slidably on the chain tooth, it is characterized in that described each chain tooth comprises matrix and is positioned at the wedge head of matrix front end, wherein, be respectively equipped with the wedge shape sprocket on the two side of described wedge head, and the position that is positioned at wedge shape sprocket rear on this wedge head two side is provided with the groove that can surround the cavity that can embed for the wedge shape sprocket of offside with the wedge shape sprocket, and corresponding each chain tooth embeds by the mutually nested of its wedge head and wedge shape sprocket thereof in the cavity of its offside and seals on described two straps, rabbet together mutually reliably.
The utility model is owing to adopt and to be provided with intermeshing sprocket and to be positioned at the structure that the sprocket rear is formed with the cavity that can embed for sprocket on the wedge head two side of chain tooth, make each chain tooth of the present utility model by sprocket on its wedge head be meshing with each other and sprocket embed accordingly in the cavity of its offside and realize the sealing between corresponding each chain tooth on two straps effectively, interlocking is together reliably.Make the utility model not only guarantee the reliability of each chain tooth interlocking effectively, but also effectively the volume of the end of engagement of chain tooth is reduced to minimum, the slit between the chain tooth is controlled in the minimum zone, guarantee the favorable sealing property between the chain tooth.And has the advantage that pliability is good, can not produce curling phenomenon.
Below in conjunction with accompanying drawing the utility model is further described.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises that a pair of device has the strap 1 of some chain teeth 2 to reach the slider of zipper fastener 3 that is installed on slidably on the chain tooth 2.For the slit that solves the existing chain tooth of slide fastener in the existing structure effectively bigger, poor sealing performance, influence the antifouling thermal property of clothing, perhaps interaction and pliability are relatively poor, be easy to generate dislocation and error between the chain tooth, be assemblied in and be easy to generate curling problems such as phenomenon on the clothing, each chain tooth 2 described in the utility model comprises matrix 21 and is positioned at the wedge head 22 of matrix 21 front ends, wherein, be respectively equipped with wedge shape sprocket 221 on the two side of described wedge head 22, and the position that is positioned at wedge shape sprocket 221 rears on these wedge head 22 two sides is provided with the groove 222 that can surround the cavity that can embed for the wedge shape sprocket 221 of offside with wedge shape sprocket 221, seals in the cavity of corresponding each chain tooth 2 by the mutually nested of its wedge head 22 and wedge shape sprocket 222 its offsides of embedding thereof on described two straps 1, rabbet together mutually reliably.As shown in Figure 4, like this, make each chain tooth 2 of the present utility model by sprocket on its wedge head 22 be meshing with each other and sprocket embed accordingly in the cavity of its offside and realize the sealing between corresponding each chain tooth 2 on two straps effectively, interlocking is together reliably.Make the utility model not only guarantee the reliability of each chain tooth 2 interlockings effectively, but also effectively the volume of the end of engagement of chain tooth 2 is reduced to minimum, the slit between the chain tooth 2 is controlled in the minimum zone, guarantee the favorable sealing property between the chain tooth 2.And has the advantage that pliability is good, can not produce curling phenomenon.In order further to reduce the volume of the utility model end of engagement, the wedge head 22 of above-mentioned each chain tooth 2 is semicircle end face.For described chain tooth can be fixedly mounted on the strap 1, as shown in Figure 2, the matrix 21 of above-mentioned each chain tooth 2 is provided with and is used for each chain tooth 2 fixture is clamped groove 211 on above-mentioned strap 1.
