Description
Technical field
The present invention relates to a kind of slide fastener, particularly a kind of slide fastener of processing with metal material.
Background technology
Slide fastener is applied to 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. usually; So the slide fastener that the making metal zip fastener is used is processed by metal materials such as aluminium, copper or iron usually, along with the slide fastener development of technology, kirsite system slide fastener also occurred.
But the metal strength of aluminium is lower, so aluminium matter slide fastener is softer, causes the slide fastener coupling element easy deformation processed, and is not up to standard; Iron has enough metal strength, but the oxidation resistance of iron is relatively poor, so the irony slide fastener gets rusty easily; The same not enough problem of metal strength that exists of the slide fastener of zinc system with the 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 is to provide a kind of metal strength and oxidation resistance height, and the cheap relatively slide fastener of production cost.
Above-mentioned slide fastener comprises a pair of zipper strip and several chain teeth, and the chain tooth row row are arranged on the two zipper strip opposed edges, and two zipper strips mesh through the chain tooth or separate;
Said zipper strip comprises first side and second side; Said chain tooth comprises main body, and main body comprises first clamping part, second clamping part and head, and first clamping part and second clamping part extend toward the same side on head; And first flanked of first clamping part and zipper strip; Second flanked of second clamping part and zipper strip is fixed between first clamping part and second clamping part zipper strip
Said 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, no pressing integument on the occlusal surface of chain tooth.
Because adopt single metal of planting to process the problem that there is the low or oxidation resistance difference of metal strength easily in slide fastener, and integument has preferred metal intensity and oxidation resistance, so through metal strength and the oxidation resistance that integument can improve slide fastener 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 the chain tooth surface fully, and does not have the integument that covers pressing on the occlusal surface of chain tooth of the present invention, thereby technical scheme of the present invention is different from prior art; Be pressed together on the chain tooth though integument of the present invention can not cover fully, the material of main body all possesses certain oxidation resistance in making, thereby there is not the problem of easy oxidation basically in chain tooth of the present invention; And the anti oxidation layer of plating is thinner, can not play the metal strength effect of reinforcement chain tooth, but the present invention is pressed together on the integument covering on the chain tooth the anti-oxidant bed thickness that the thickness of integument ratio is electroplated, the purpose of realization reinforcement chain tooth metal strength; And the occlusal surface of chain tooth can also be painted, makes the color category of chain tooth more, more meets the market individual demand.
Usually adopt electroplating technology to cause bigger pollution, also be unfavorable for the healthy of staff, adopt covering pressing structure of the present invention not pollute the environment, also can staff's health not damaged environment.
Preferably, the material of said chain tooth is aluminium alloy, ferroalloy, kirsite, copper or copper alloy; The material of said integument is copper or copper alloy.
The main composition of slide fastener partly is zipper strip and chain tooth; Because the chain tooth of slide fastener according to the invention is made up of two kinds of different metallic; So can select cheap metal and high-test metal combined and make the chain tooth; The quality that this not only can guarantee the chain tooth has also reduced chain tooth production cost, because copper or copper alloy all have oxidation resistance and metal strength preferably; So adopt copper or copper alloy both to guarantee the oxidation resistance of chain tooth, also guaranteed the metal strength of chain tooth as the integument of chain tooth.
Aluminium alloy, ferroalloy, zinc or the kirsite all price than copper or copper alloy are low, so the 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 following:
Because the price of aluminium alloy is low, density is little and oxidation resistance is strong, so, have the excellent antioxidation ability by low, the light weight of chain tooth cost of manufacture of aluminium alloy system; But the metal strength of aluminium alloy is lower; The chain tooth easy deformation of processing by aluminium alloy, so the durability of zipper that the chain tooth is processed is not high, though and the metal strength of part aluminium alloy near in addition surpass steel; Solved the lower problem of Al-alloy metal intensity; But too much other elements owing to mixed, thus cause the oxidation resistance of aluminium alloy to reduce greatly, thereby the chain tooth that adopts this kind aluminium alloy to process gets 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; Remedied the low deficiency of chain tooth metal strength of aluminum or aluminum alloy system; For the aluminium alloy that improves metal strength because of other elements that mix 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 processed by ferroalloy is low, and metal strength is high; But the oxidation resistance of ferroalloy is poor, and the chain tooth of being processed by ferroalloy gets rusty easily, and wherein stainless steel is a kind of in the ferroalloy; Though it has excellent antioxidation ability and outstanding metal strength; Solved the problem of the oxidation resistance difference 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; Increase the oxidation resistance of slide fastener, remedied the deficiency of the slide fastener oxidation resistance difference of ferroalloy system, special in slide fastener with stainless steel; Chain tooth to being processed by stainless steel only need be processed roughly; Again to the copper of integument or copper alloy carry out retrofit just can, thereby reduced requirement to process equipment, reduce input cost to equipment.
The price of kirsite is low, and oxidation resistance is stronger, so low by the chain tooth cost of manufacture of kirsite system; Have the excellent antioxidation ability, but the metal strength of kirsite is lower, yielding by the slide fastener coupling element that kirsite is processed; So the durability of zipper that the chain tooth is processed is not high, and the metal strength of part kirsite is higher, has solved the lower problem of zinc alloy metal intensity; But such kirsite corrosion resistance is poor, if the lead impurity element in the alloy, cadmium, when tin is above standard will cause kirsite aging and deform; Show as volume and swell, mechanical performance particularly plasticity significantly descends, and the time has been grown even broken.
Be pressed together on the slide fastener of kirsite system so adopt copper or copper alloy to cover, increased the metal strength of chain tooth, remedied the low deficiency of slide fastener metal strength of kirsite system; Especially for the 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 kirsite has broken, owing to there is the integument of copper or copper alloy system to cover; So the kirsite that breaks can not expose yet, thereby the outward appearance that does not also influence slide fastener is used with normal.
The scheme that also has copper-clad copper is 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 the object of the invention.

Though the metal strength of part aluminium alloy near in addition surpass steel; Solved the lower problem of metal strength of aluminium; But too much other metals owing to mixed, thus cause the oxidation resistance of aluminium alloy to reduce greatly, thereby the chain tooth that adopts this kind aluminium alloy to process gets rusty easily.
Can solve the problem that its oxidation resistance descends so adopt copper to cover on the chain tooth of the aluminium alloy system that is pressed together on.
Said 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; Said thickening part 12 is located on the edge of plat part 11, and the first clamping part 3A and the second clamping part 3B carry out clamping to plat part 11, makes thickening part 12 inlay cards between the first clamping part 3A and the second clamping part 3B.
Because the chain tooth on zipper strip fixedly clamping realizes to zipper strip through clamping part, if zipper strip is merely a smooth belt body, then zipper strip is easily because of being drawn out in clamping part by external force, causes separating of zipper strip and chain tooth; And be provided with thickening part 12 in the above-mentioned preferred version; 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 receives the external force effect, the first clamping part 3A and the second clamping part 3B apply an inside pressure to zipper strip; Make zipper strip be not easy to separate, be connected with the chain tooth more fastening, thereby improved the durability of slide fastener.
Preferably, be provided with concave surface 61 outward successively and press face 5 from interior on the opposite face of the said first clamping part 3A and the second clamping part 3B, in it, the said face 5 that presses is the plane to said concave surface 61 with thickening part 12 inlay cards, and presses face 5 and join with plat part 11.
Because the inboard of the opposite face of the first clamping part 3A and the second clamping part 3B is provided with concave surface 61; The institute think that thickening part 12 inlay cards have left the 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; Be located on the outside of opposite face of the first clamping part 3A and the second clamping part 3B and press face 5, with further clamping zipper strip, to strengthen the tight ness rating that is connected between chain tooth and the zipper strip.
Further, said concave surface 61 is provided with tip 62, and tip 62 joins with thickening part 12 and thickening part 12 is inwardly pressed.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 with thickening part 12 and it exerted pressure, make thickening part 12 can better inlay card in concave surface 61.
In addition, said head 2 comprises the first side 9A and the second side 9B, and the first side 9A of head 2 is provided with projection 7, and the second side 9B of head 2 is provided with pit 8, and projection 7 is corresponding with the position that pit 8 is provided with, size is complementary.

Said head 2 comprises first surface 4A and second surface 4B, and first surface 4A and second surface 4B are the plane.
After described first surface 4A and second surface 4B are meant that the chain tooth is fixed in zipper strip; The face of chain tooth and zipper strip opposing parallel then is described surface; Make the surfacing of chain tooth, thereby slide fastener drawing when opening more smooth and easyly, be not easy card; Wherein, do not limit the side that first surface 4A or second surface 4B are located at chain tooth fixed-direction.
Further, 10 of said chain tooth and integuments are seamless link.
Because covering, integument 10 is pressed together on outside the chain tooth; So integument 10 part positions occur causing integument 10 to peel off easily after the wearing and tearing; And 10 of chain tooth and integuments are seamless link; Be that chain tooth and integument 10 are one-body molded, thus even appearring in integument 10 part positions, wearing and tearing can not cause peeling off of integument 10 yet, thus improved the quality of slide fastener.
Wherein, said integument 10 is 3: 7 with the mass ratio of chain tooth.
Because the main effect 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 uses minimum material to reach the metal strength of raising slide fastener and the effect of oxidation resistance; And when the mass ratio of integument 10 and chain tooth was 3: 7, integument 10 just can realize improving the metal strength of slide fastener and the effect of oxidation resistance, thereby has reduced the cost of manufacture of slide fastener as far as possible.
Second kind of embodiment of the present invention and first kind of embodiment basically identical, its difference is: the material of said chain tooth is a ferroalloy.
Because copper has oxidation resistance and metal strength preferably,, also guaranteed the metal strength of chain tooth so adopt copper both to guarantee the oxidation resistance of chain tooth as the integument of chain tooth.
And the price of ferroalloy is lower than the price of copper, so the 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 following:
Stainless steel is a kind of in the ferroalloy; Though it has excellent antioxidation ability and outstanding metal strength; Solved the problem of the oxidation resistance difference 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; Increase the oxidation resistance of chain tooth, remedied the deficiency of the chain tooth oxidation resistance difference of ferroalloy system, special in chain tooth with stainless steel; Chain tooth to being processed by stainless steel only need be processed roughly; Again to the copper of integument 10 carry out retrofit just can, thereby reduced requirement to process equipment, thereby reduce input cost to equipment.
The third embodiment of the present invention and first kind of embodiment basically identical, its difference is: the material of said chain tooth is a kirsite.
Because copper has oxidation resistance and metal strength preferably,, also guaranteed the metal strength of chain tooth so adopt copper both to guarantee the oxidation resistance of chain tooth as the integument 10 of chain tooth.
And the price of kirsite is lower than the price of copper, so the 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 following:
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, if the lead impurity element in the alloy, cadmium, when tin is above standard; To cause kirsite aging and deform; Show as volume and swell, mechanical performance particularly plasticity significantly descends, and the time has been grown even 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 is integument made of copper 10 to cover; So the kirsite that breaks can not appear outside yet, thereby the outward appearance that does not also influence the chain tooth is used with normal.
The 4th kind of embodiment of the present invention and first kind of embodiment basically identical, its difference is: the material of said chain tooth main body is a copper.
Because various copper prices differ, as long as main body adopts the low copper of price still can reach the object of the invention.
The 5th kind of embodiment of the present invention and first kind of embodiment basically identical, its difference is: the material of said chain tooth main body is a copper alloy.
Because each Albatra metal-price differs, as long as main body adopts the low copper alloy of price still can reach the object of the invention.
Among wherein above-mentioned five embodiment, the material of integument 10 can also replace with copper alloy, and said zipper strip can be zipper cloth belt, and still can make the chain tooth of processing have above-mentioned beneficial effect.
The improved protection domain that also is regarded as patent on the basis of above embodiment.
