Abstract
A steel nail with a head portion in an inner arc triangular pyramid shape is composed of a nail head, a nail body and a nail tail. The nail head is in an inner arc triangular pyramid shape, and three edge peaks and three inner arc edge valleys form three edges with three equal angles. The nail head portion is from a nail point to the tail end of the edge peak and occupies one third of the overall length of the steel nail. Three edge peaks of the nail head and three inner arc edge valleys of the nail head occupy about one third of the overall length of the steel nail. The steel nail with the head portion in the inner arc triangular pyramid shape the inner arc triangular pyramid shape aims at reducing a hindered area of the nail head in the wall body. The nail body is in a cylinder shape, the nail tail is in a cake shape, and from the nail head portion to the nail body to the nail tail is a stick which is made of quality steel with the same material.
Description
Affiliated technical field
The utility model relates to the hardware fitting field, specifically, relates to a kind of steel nail of hardware fastening class.
Background technique
Existing concrete steel nail head is that four ribs are pointed, and each side is the plane, and therefore, it is larger to be subject to drag area.Generally, be only applicable to the low concrete wall of label, and in case when meeting the high concrete wall of label or hard brick wall, the phenomenon that steel nail is bent and fractures often occurs.
Summary of the invention
Be that four ribs are pointed in order to overcome existing concrete steel nail head, each side is the plane, and it is larger to be subject to drag area, and the phenomenon that steel nail is bent and fractures often occurs.The utility model provides the steel nail of a kind of head inner arc triangular taper.The steel nail of this head inner arc triangular taper, it not only reduces steel nail head and body of wall lifting surface area, and has overcome the phenomenon that steel nail is obstructed and is bent and fractures.
The technological scheme that its technical problem that solves the utility model adopts is: it is made of ailhead, nail body and nail tail.Ailhead is the taper of inner arc triangular, formed by three rib peaks and three inner arc rib paddy three equal equal angular three ribs, and described ailhead partly is exactly terminal from nail tip to the rib peak, accounts for steel nail overall length about 1/3rd.Three rib peaks of ailhead and three inner arc rib paddy shapes, the purpose that accounts for about 1/3rd designs of steel nail overall length is, in order to reduce the be obstructed area of ailhead in body of wall.The nail body is cylindrical, and the nail tail is patty, assigns to the nail body until the nail tail is the high-quality steel of a same material from nail head.
The beneficial effects of the utility model are: reduce the area that is obstructed of steel nail head and body of wall, overcome steel nail and be obstructed and be bent and fracture.
