The utility model content
The utility model recognizes that first the thickness of coating on drawing head body surface is on the impact of the slip smoothness of slider of zipper fastener, recognize existing drawing head body owing to adopting electroplating technology, in the formed thickness of coating in drawing head body surface all more than 8 μ m, so that the space in the chain tooth hole diminishes, very trickle also being easy to of this change in size ignored by the people, but directly cause glade plane space between chain tooth and the chain tooth hole to diminish and so that the slip smoothness of slider of zipper fastener be affected, thereby easily produce the phenomenon of " cassette tape ".
Based on above-mentioned analysis, the purpose of this utility model is to provide a kind of slider of zipper fastener that is difficult for " cassette tape ", and the technical scheme that adopts is as follows:
A kind of slider of zipper fastener comprises drawing head body and pulling-on piece, and described drawing head body and pulling-on piece link, and is coated with one deck electrophoretic paint on the surface of described drawing head body, and the thickness of described electrophoretic paint is less than 8 μ m.
Slider of zipper fastener provided by the utility model, because the lip-deep electrophoretic paint of its drawing head body plates by electrophoresis coating technique, and the resulting thickness of coating of electrophoresis coating technique can be as thin as below the 2 μ m, therefore the thickness of electrophoretic paint can be controlled at below the 8 μ m, simultaneously, the electrophoretic paint thickness that covers on the hole wall in chain tooth hole also is controlled at below the 8 μ m, " cassette tape " occurs with regard to being difficult for so that leave larger glade plane space between chain tooth and the chain tooth hole in this, thereby improves the slip smoothness of slider of zipper fastener.In addition, because the compact dimensions of drawing head body itself does not change, the size in chain tooth hole does not change yet, therefore compare the mode that enlarges glade plane space by the size that changes chain tooth hole, the problem that the utility model has easily taken off tooth after having avoided the chain tooth because of the oversize and difficult engagement in chain tooth hole or engagement.
In order further to optimize the utility model, the thickness of described electrophoretic paint is 2 μ m.Through experimental results show that, slider of zipper fastener under this thickness, need not to take in addition to apply the lubricant methods such as lubricant namely slidably smooth and easy, be difficult for occuring " cassette tape ", and the electrophoretic paint that covers on the hole wall in chain tooth hole also is difficult for because wearing and tearing come off, and illustrates and leaves enough glade plane spaces between chain tooth and the chain tooth hole; On the other hand,, then be difficult to reach the surface treatment requirement and easily come off not because of the adhesive force of electrophoretic paint less than 2 μ m if the thickness of electrophoretic paint is too thin.Comprehensive above-mentioned reason, the THICKNESS CONTROL of electrophoretic paint is best at 2 μ m.
In order further to optimize the utility model, described electrophoretic paint is cathode electrodip painting.
In order further to optimize the utility model, the material of described drawing head body is aluminium alloy.
