Abstract
The utility model relates to a nail whose crosscut area is reduced, which is characterized in that the nail rod is provided with at least four troughs with concave cylindrical surfaces, hyperbolic cylinders or parabolic cylinders. The material for making the nail can be greatly saved, the cost can be reduced, and the buckling strength or the adhesive force of the nail to the nailed object can be improved. The nail is an ideal product.
Description
The utility model relates to a kind of nail that dwindles cross-sectional area.
Present employed nail has wire nail and the boat nail used of system leather shoes, and though be wire nail or boat nail all owing to circle on its cross-section or squarely determined that the bending resistance of unit diameter thickness is less, also make its adhesion less because of surface area is less.The Chinese patent communique on October 8th, 1986 disclosed a kind of name, and to be called the iron nails with barbs in oblique triangular con-shape and elevation-angle application number be 85107404 application for a patent for invention, the technological scheme of this application mainly is: " around the mast of the ancient iron nail of common polished rod; with die-cut way; regularly will process thin capable oblique triangular con-shape and elevation-angle hangnail ", with the adhesion of increase iron nail, but resistance to flexure is reduced owing to cut processing.
The nail that the purpose of this utility model is to provide a kind of mast cross-section of nail to be at least four stupefied shapes make its cross-section relatively more circular, square nail little, and the mast surface area is big, and resistance to flexure strengthens, and reaches the quality that improves nail, and the purpose of cutting down the consumption of raw materials.
Better according to arc surface, parabola, bi-curved mechanical characteristic, higher transverse property is arranged, so the utility model is made up of the head of a nail, nail bar, nail point, at least four stupefied shapes are adopted in nail bar cross-section, each stupefied summit circular arc all is isocentric circular arc, has four grooves on the mast at least, but each groove hyperbolic cylinder, perhaps parabolic cylinder, perhaps cylndrical surface.
Advantage of the present utility model is, the nail of equality strength, and relatively the tradition nail is saved the material 50% or more, has reduced manufacture cost, and easier hammering into followed closely in the thing when using, and adhesion is stronger.
Accompanying drawing one is the utility model structural representation.
Accompanying drawing two is the utility model nail bar cross-section structural representation.
Describe below in conjunction with implementing that the utility model is done a step, but be not limited to embodiment.
By adding cold-drawing technology one on the present rounding nail technology, make its nail post make four stupefied shapes, it constitutes four stupefied concave surfaces is hyperbolic cylinder.
By adding cold-drawing technology one on the present rounding nail technology, make its nail post make five stupefied shapes, it constitutes four stupefied concave surfaces is the cylndrical surface.
By adding cold-drawing technology one on the present rounding nail technology, make its nail post make six stupefied shapes its all to become six stupefied concave surfaces be parabolic cylinder.
Claims (4)
1, a kind of abnormity nail, it is made of the head of a nail, nail bar, nail point, it is characterized in that following closely having four grooves on the bar at least.
2, abnormity nail according to claim 1, the groove that it is characterized in that following closely on the bar is the cylndrical surface.
3, abnormity nail according to claim 1, the groove that it is characterized in that following closely on the bar is a hyperboloid.
4, abnormity nail according to claim 1, the groove that it is characterized in that following closely on the bar is a parabolic cylinder.
