Abstract
The utility model relates to a novel nail which is composed of a nail head, a nail rod and a nail cap and is characterized in that the surface of the nail rod is provided with a plurality of annular grooves which are mutually independent; the grooves are evenly distributed at the surface of the nail rod in the way of a jagged shape through the rolling fabrication process; the depths of the grooves are from 0.1 to 0.3 mm according to different length of nail series. The nail adopts the rolling cold rolling process to manufacture the grooves at the surface of the nail body, which can improve the strength of the nail body and the surface. After material which is nailed is bumped and pressed, the recovery part for elastic deformation of the material can be directly embedded into the annular grooves, which can enhance fastening force and withdrawal resistance ability of the nail body. Adhered glue can be coated in the circular grooves, which can increase the withdrawal resistance of the nail.
Description
The utility model relates to a kind of new sprig, and this ailing surface is processed with groove.
The existing over one hundred year history of tradition wire nail, owing to himself there is certain defective, the nail body is smooth, friction is less, is subjected to vibration loosening or come off when connecting Wood member easily.So use traditional wire nail just can reach required linking intensity with the nail amount by increasing, wasting phenomena is comparatively general.
For solving the problems referred to above that traditional wire nail exists, CN2128910U, CN2174506Y have introduced two kinds of new structure nails respectively.Above-mentioned nail all is processed with in the nail surface and is screw-like channels, makes the nail body have both wire nail and wood screw function around its spin.Above-mentioned nail body is the processing technology complexity not only, and nail surface groove can't deposit glue, also also is extruded with nail body spiral grooves after both having made viscose glue, does not reach the gluing purpose.
The purpose of this utility model is to provide a kind of new sprig, and this ailing surface is processed with some separate grooves, is used to overcome above-mentioned existing in prior technology shortcoming.
The utility model above-mentioned purpose is finished like this: a kind of new sprig, this nail is made up of ailhead, nail body, the head of a nail, it is characterized in that said nail surface is processed with the annular ditch groove of several independent.
The utility model is processed with the annular ditch groove of several independent in the nail surface, not only can make be tufted into material and be squeezed after, utilize its elasticity sex change recovered part directly to embed in the annular ditch groove, strengthen nail body fastening force and resistance to plucking ability, and for the bigger fastening force occasion of some needs, only need in above-mentioned annular ditch groove, to be coated with some adhesive glues, and the viscose glue in the groove can not be extruded as wire nail or spiral nail when hammering into.The utility model processing technology is simple, and nail body and surface strength height thereof are difficult for bending.
Introduce specific embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
By accompanying drawing as can be seen, this new sprig comprises ailhead 1, nail body 3 and the head of a nail 4, nail body 3 surface Machining have the annular ditch groove 2 of several independent, these groove 2 best indentations are evenly distributed on the nail surface, sawtooth is preferably 45 ° with nail body 3 axis angles, and above-mentioned ditch groove deep is 0.1～0.3mm according to the long serial working depth of difference nail.
Claims (4)
1. new sprig, this nail is made up of ailhead [1], nail body [3], the head of a nail [4], it is characterized in that said nail body [3] surface Machining has the annular ditch groove [2] of several independent.
