Abstract

The utility model discloses a knurled ball-head nail with a gasket, which mainly comprises a nail rod and a nail head, wherein the nail head takes the shape of a ball; the joint between the nail head and the nail rod transits through a smooth curved surface; a small plane is arranged at the outermost side of the nail head in the nail rod direction; a decorative pattern formed through rolling is arranged on the surface of the nail rod; and the gasket which is vertical to the nail rod is arranged on the nail rod. The nail head takes the shape of a ball and the small plane is arranged at the outermost side of the nail head so that the stressed area of the nail is enlarged and the impact force suffered by the nail is increased when the ball-head nail is used in a nail ejector. Furthermore, the gasket with the diameter being 12mm ensures that an object can be fixed more firmly and can centralize the nail when being matched with the nail ejector for use. On the other hand, as the decorative pattern is rolled on the surface of the nail rod, the defect that the nail in a steel plate is easy to loosen is overcome, the nail is fixed more firmly without loosening easily and the length of the nail in a substrate can be shortened.

Description

The annular knurl button of band pad

Technical field

The utility model relates to system nail industry, especially a kind of annular knurl button with pad.

Background technique

Employed on the market nail generally all is to use by artificial or air gun, because its intensity and impact force is limited, makes nail can't hammer into some hard objects, as concrete, steel plate etc.If on concrete, hammer into nail, must expend bigger manpower, in case and active force generation deflection, cause nail to come off easily or concrete bursts apart.General in addition polished rod nail is after hammering into steel plate inside, because the expansion coefficient of steel plate is low and under the effect of the power of vertical nail bar direction, can make the polished rod nail loosening even come off.On the other hand, at present on the market common nail all is not suitable in nailing device and uses.

The model utility content

The purpose of this utility model is that a kind of dapple button that can cooperate the band pad of nailing device use in bar surface of following closely is provided for the deficiency that solves above-mentioned technology.

In order to achieve the above object, the annular knurl button of the band pad that the utility model is designed, it mainly comprises nail bar and ailhead, ailhead is a ball-shaped, ailhead passes through the smooth curved surface transition with the joint of nail bar, the outermost of ailhead is provided with a facet on nail bar direction, is provided with the decorative pattern that forms by roll extrusion on nail bar surface, is provided with pad perpendicular to the nail bar on the nail bar.It is more firm that such structure setting hammers into behind body of wall or the steel plate nail, difficult drop-off.

The diameter of above-mentioned pad is 12mm, and such size setting can cooperate the nail pipe of nailing device to use.

The annular knurl button of the resulting band pad of the utility model, its ailhead are ball-shaped, and after nail hammered on the steel plate, external structure was more attractive in appearance, and can not draw clothes or human body.And a facet is set in the outermost of ailhead, and when button is used, increase the lifting surface area of nail in nailing device, increase the impact force that nail is subjected to, make in its easier person's of hammering into steel plate, but also make nail not yielding.The pad setting of 12mm in addition both can make object fixing more firm, can also play the effect of setting upright to nail when being used with nailing device.On the other hand, the decorative pattern setting of the roll extrusion on nail bar surface can overcome the defective of nailing and become flexible easily in steel plate inside, can make nail fixing more firm, is difficult for loosening.But also can shorten the length that nail hammers into matrix, and saved material, reduced cost of production, brought huge economic benefit to enterprise.
