Technical field
The present invention relates to a kind of slide fastener, particularly a kind of slide fastener made from metal material.
Background technology
Slide fastener is applied to the various fields such as leatherware, dress ornament, common slide fastener can be divided into nylon zipper, injection molding zipper and metal zip fastener, and metal zip fastener is divided into aluminium tooth slide fastener, copper tooth slide fastener, iron tooth slide fastener etc. conventionally, so the slide fastener that making metal zip fastener is used is made by metal materials such as aluminium, copper or iron conventionally, along with the progress of slide fastener technology, also there is kirsite slide fastener processed.
But the metal strength of aluminium is lower, so aluminium matter slide fastener is softer, cause the slide fastener coupling element of making to be easily out of shape, not up to standard; Iron has enough metal strength, but the oxidation resistance of iron is poor, so irony slide fastener gets rusty easily; The slide fastener of the zinc system problem that have metal strength deficiency the same as aluminum slide fastener; And copper has enough metal strength and oxidation resistance, so copper slide fastener is comparatively general, but the price of copper is higher, and therefore slide fastener price made of copper is higher.
Summary of the invention
The object of the invention be to provide a kind of metal strength and oxidation resistance high, and the relatively cheap slide fastener of production cost.
Above-mentioned slide fastener comprises a pair of zipper strip and several chain teeth, and chain tooth row row are arranged on the edge that two zipper strips are relative, and two zipper strips mesh by chain tooth or be separated;
Described zipper strip comprises the first side and the second side, described chain tooth comprises main body, main body comprises the first clamping part, the second clamping part and head, the first clamping part and the second clamping part extend toward the same side on head, and the first side of the first clamping part and zipper strip joins, the second side of the second clamping part and zipper strip joins, and zipper strip is fixed between the first clamping part and the second clamping part
Described chain tooth also comprises the integument of strengthening slide fastener wire rod physical property and oxidation resistance, and integument covers the periphery surface that is pressed together on chain tooth main body, on the occlusal surface of chain tooth without pressing integument.
Because adopt single kind metal to make slide fastener, easily have the problem that metal strength is low or oxidation resistance is poor, and integument has good metal strength and oxidation resistance, so can improve metal strength and the oxidation resistance of slide fastener by integument is set.
Prior art is in order to improve the oxidation resistance of chain tooth, the chain tooth surface of being everlasting is electroplated one deck anti oxidation layer, this anti oxidation layer can cover chain tooth surface completely, and the integument of nothing covering pressing on the occlusal surface of chain tooth of the present invention, thereby technical scheme of the present invention is different from prior art; Although integument of the present invention can not cover completely, be pressed together on chain tooth, in making, the material of main body all possesses certain oxidation resistance, thereby chain tooth of the present invention does not exist the problem of easy oxidation substantially; And the anti oxidation layer of plating is thinner, can not play the metal strength effect of strengthening chain tooth, but the present invention covers integument to be pressed together on chain tooth, the anti-oxidant bed thickness that the Thickness Ratio of integument is electroplated, the object of realization reinforcement chain tooth metal strength; And the occlusal surface of chain tooth can also be painted, make the color category of chain tooth more, more meet market individual demand.
Conventionally adopt electroplating technology to cause larger pollution to environment, be also unfavorable for the healthy of staff, adopt covering pressing structure of the present invention not pollute the environment, also can not damage staff's health.
Preferably, the material of described chain tooth is aluminium alloy, ferroalloy, kirsite, copper or copper alloy; The material of described integument is copper or copper alloy.
The main composition of slide fastener is partly zipper strip and chain tooth, because the chain tooth of slide fastener of the present invention consists of two kinds of different metals, so can select cheap metal and high-test metal combined and make chain tooth, this not only can guarantee the quality of chain tooth, also reduced chain tooth production cost, because copper or copper alloy all have good oxidation resistance and metal strength, so adopt copper or copper alloy both to guarantee the oxidation resistance of chain tooth as the integument of chain tooth, also guaranteed the metal strength of chain tooth.
Aluminium alloy, ferroalloy, zinc or kirsite are all low than the price of copper or copper alloy, so chain tooth adopts above-mentioned metal as main material, have reduced the use amount of copper or copper alloy, thereby the cost of manufacture of chain tooth is reduced.
Directly do not adopt the main cause of aluminium alloy, ferroalloy or kirsite making chain tooth as follows:
Because the price of aluminium alloy is low, density is little and oxidation resistance is strong, so the chain tooth cost of manufacture by aluminium alloy system is low, quality is light, there is outstanding oxidation resistance, but the metal strength of aluminium alloy is lower, the chain tooth of being made by aluminium alloy is easily out of shape, therefore the durability of zipper that chain tooth is made is not high, and although the metal strength of part aluminium alloy approaches even over steel, solved the lower problem of Al-alloy metal intensity, but due to too much other elements that adulterated, thereby cause the oxidation resistance of aluminium alloy greatly to reduce, thereby adopt the chain tooth that this kind of aluminium alloy made to get rusty easily.
So adopting copper or copper alloy to cover is pressed together on the chain tooth of aluminum or aluminum alloy system, increased the metal strength of chain tooth, made up the low deficiency of chain tooth metal strength of aluminum or aluminum alloy system, for improve the aluminium alloy of metal strength because of other elements that adulterate too much, adopt copper or copper alloy to cover and be pressed together on the problem that its surface can solve its oxidation resistance decline especially.
The price of ferroalloy is low high with metal strength, so the chain tooth cost of manufacture of being made by ferroalloy is low, and metal strength is high, but the oxidation resistance of ferroalloy is poor, the chain tooth of being made by ferroalloy gets rusty easily, wherein stainless steel is a kind of in ferroalloy, although it has outstanding oxidation resistance and outstanding metal strength, solved the poor problem of oxidation resistance of iron, but because stainless metal strength is too high, so make chain tooth processing difficulties with stainless steel, process equipment is had relatively high expectations, thereby increased the input cost of equipment.
Adopting copper or copper alloy to cover is pressed together on the slide fastener of ferroalloy system, increased the oxidation resistance of slide fastener, made up the poor deficiency of slide fastener oxidation resistance of ferroalloy system, special in the slide fastener with stainless steel, the chain tooth of being made by stainless steel is only needed to process roughly, again to the copper of integument or copper alloy carry out retrofit just can, thereby reduced the requirement to process equipment, reduce the input cost to equipment.
The price of kirsite is low, oxidation resistance is stronger, so the chain tooth cost of manufacture by kirsite system is low, there is outstanding oxidation resistance, but the metal strength of kirsite is lower, the slide fastener coupling element of being made by kirsite is yielding, therefore the durability of zipper that chain tooth is made is not high, and the metal strength of part kirsite is higher, solved the lower problem of zinc alloy metal intensity, but such kirsite corrosion resistance is poor, if the lead impurity element in alloy, cadmium, when tin is above standard, to cause kirsite aging and deform, showing as volume swells, mechanical performance particularly plasticity significantly declines, time has been grown even and has broken.
So adopting copper or copper alloy to cover is pressed together on the slide fastener of kirsite system, increased the metal strength of chain tooth, made up the low deficiency of zipper metal intensity of kirsite system, especially for part kirsite, adopt copper or copper alloy to cover and be pressed together on the expansion that kirsite can be limited in its surface, even if kirsite has broken, owing to there being the integument of copper or copper alloy system to cover, so the kirsite breaking can not expose yet, thereby do not affect the outward appearance of slide fastener yet and normally use.
Also there is the scheme of copper-clad copper, because the price of various copper and copper alloy differs, as long as main body adopts low copper or the copper alloy of price still can reach object of the present invention.
Preferably, described zipper strip comprises plat part and thickening part, it is banded that plat part is, its thickness is less than thickening part, described thickening part is located on the edge of plat part, and the first clamping part and the second clamping part clamp plat part, make thickening part inlay card between the first clamping part and the second clamping part.
Because chain tooth fixedly clamps to realize to zipper strip by clamping part on zipper strip, if zipper strip is only a smooth belt body, zipper strip, easily because pulled out in clamping part by external force, causes zipper strip separated with chain tooth; In above-mentioned preferred version, be provided with thickening part, the thickness of thickening part is greater than plat part, and thickening part inlay card is between the first clamping part and the second clamping part, so even zipper strip is subject to External Force Acting, the first clamping part and the second clamping part apply an inside pressure to zipper strip, zipper strip and chain tooth are not easy separated, fixing more firm, thereby have improved the durability of slide fastener.

Although approaching, the metal strength of part aluminium alloy even surpasses steel, solved the lower problem of metal strength of aluminium, but due to too much other metals that adulterated, thereby cause the oxidation resistance of aluminium alloy greatly to reduce, thereby adopt the chain tooth that this kind of aluminium alloy made to get rusty easily.
So adopt copper to cover on the chain tooth of the aluminium alloy system that is pressed together on, can solve the problem that its oxidation resistance declines.
Described zipper strip comprises plat part 11 and thickening part 12, it is banded that plat part 11 is, and the thickness of plat part 11 is less than the thickness of thickening part 12, described thickening part 12 is located on the edge of plat part 11, and the first clamping part 3A and the second clamping part 3B clamp plat part 11, make thickening part 12 inlay cards between the first clamping part 3A and the second clamping part 3B.
Because chain tooth fixedly clamps to realize to zipper strip by clamping part on zipper strip, if zipper strip is only a smooth belt body, zipper strip is easily because being drawn out by external force in clamping part, causes the separated of zipper strip and chain tooth; And in above-mentioned preferred version, be provided with thickening part 12, the thickness of thickening part 12 is greater than plat part 11, and thickening part 12 inlay cards are between the first clamping part 3A and the second clamping part 3B, so even zipper strip is subject to External Force Acting, the first clamping part 3A and the second clamping part 3B apply an inside pressure to zipper strip, make zipper strip and chain tooth be not easy separated, be connected more fastening, thereby improved the durability of slide fastener.
Preferably, on the opposite face of described the first clamping part 3A and the second clamping part 3B, from interior, be provided with successively outward concave surface 61 and press face 5, described concave surface 61 by thickening part 12 inlay cards in the inner, described in press face 5 for plane, and press face 5 and join with plat part 11.
Because the inner side of the opposite face of the first clamping part 3A and the second clamping part 3B is provided with concave surface 61, institute think that thickening part 12 inlay cards have left space between the first clamping part 3A and the second clamping part 3B, make thickening part 12 securely inlay card between the first clamping part 3A and the second clamping part 3B; And press face 5, be located on the outside of opposite face of the first clamping part 3A and the second clamping part 3B, further to clamp zipper strip, to strengthen the tight ness rating that is connected between chain tooth and zipper strip.
Further, described concave surface 61 is provided with tip 62, and most advanced and sophisticated 62 join and thickening part 12 is inwardly pressed with thickening part 12.Because it is most advanced and sophisticated 62 that concave surface 61 is provided with, and thickening part 12 inlay cards are in concave surface 61, thus most advanced and sophisticated 62 join and it exerted pressure with thickening part 12, make thickening part 12 can better inlay card in concave surface 61.

Further, 10 of described chain tooth and integuments are seamless link.
Because covering, integument 10 is pressed together on outside chain tooth, so integument 10 part positions occur easily causing integument 10 to peel off after wearing and tearing, and 10 of chain tooth and integuments are seamless link, be that chain tooth and integument 10 are one-body molded, even if so integument 10 part positions occur that wearing and tearing can not cause peeling off of integument 10 yet, thereby improved the quality of slide fastener.
Wherein, described integument 10 is 3: 7 with the mass ratio of chain tooth.
Because the Main Function of integument 10 is metal strength and the oxidation resistances that improve slide fastener, and the cost of integument 10 materials is higher than the cost of chain tooth material, so the optimum integument 10 that is chosen as is used minimum material to reach the raising metal strength of slide fastener and the effect of oxidation resistance, and when the mass ratio of integument 10 and chain tooth is 3: 7, integument 10 just can be realized and improve the metal strength of slide fastener and the effect of oxidation resistance, thereby has reduced as far as possible the cost of manufacture of slide fastener.
The second embodiment of the present invention and the first embodiment are basically identical, and its difference is: the material of described chain tooth is ferroalloy.
Because copper has good oxidation resistance and metal strength, so adopt copper both to guarantee the oxidation resistance of chain tooth as the integument of chain tooth, also guaranteed the metal strength of chain tooth.
And the price of ferroalloy is lower than the price of copper, so chain tooth adopts ferroalloy to reduce the use amount of copper as material, thereby the cost of manufacture of chain tooth is reduced.
And directly do not adopt the main cause of ferroalloy making chain tooth as follows:
Stainless steel is a kind of in ferroalloy, although it has outstanding oxidation resistance and outstanding metal strength, solved the poor problem of oxidation resistance of iron, but because stainless metal strength is too high, so make chain tooth processing difficulties with stainless steel, process equipment is had relatively high expectations, thereby increased the input cost of equipment.
So adopting copper to cover is pressed together on the chain tooth of ferroalloy system, increased the oxidation resistance of chain tooth, made up the poor deficiency of chain tooth oxidation resistance of ferroalloy system, special in the chain tooth with stainless steel, the chain tooth of being made by stainless steel is only needed to process roughly, again to the copper of integument 10 carry out retrofit just can, thereby reduced the requirement to process equipment, thereby reduce the input cost to equipment.
The third embodiment of the present invention and the first embodiment are basically identical, and its difference is: the material of described chain tooth is kirsite.
Because copper has good oxidation resistance and metal strength, so adopt copper both to guarantee the oxidation resistance of chain tooth as the integument 10 of chain tooth, also guaranteed the metal strength of chain tooth.
And the price of kirsite is lower than the price of copper, so chain tooth adopts kirsite to reduce the use amount of copper as material, thereby the cost of manufacture of chain tooth is reduced.
And directly do not adopt the main cause of kirsite making chain tooth as follows:
Because the metal strength of part kirsite is higher, solved the lower problem of metal strength of zinc, but such kirsite corrosion stability is poor, when if the lead impurity element in alloy, cadmium, tin are above standard, to cause kirsite aging and deform, show as volume and swell, mechanical performance particularly plasticity significantly declines, and the time has been grown even and broken.
So adopting copper to cover is pressed together on the chain tooth of kirsite system, can limit the expansion of kirsite, even and kirsite broken, owing to there being integument made of copper 10 to cover, so the kirsite breaking can not appear outside yet, thereby do not affect the outward appearance of chain tooth yet and normally use.
The 4th kind of embodiment of the present invention and the first embodiment are basically identical, and its difference is: the material of described chain tooth main body is copper.
Because various copper prices differ, as long as main body adopts the low copper of price still can reach object of the present invention.
The 5th kind of embodiment of the present invention and the first embodiment are basically identical, and its difference is: the material of described chain tooth main body is copper alloy.
Because each Albatra metal-price differs, as long as main body adopts the low copper alloy of price still can reach object of the present invention.
Wherein, in above-mentioned five embodiment, the material of integument 10 can also replace with copper alloy, and described zipper strip can be zipper cloth belt, and still can make the chain tooth of making have above-mentioned beneficial effect.
The improved protection domain that is also considered as patent on the basis of above embodiment.
