Abstract
The utility model discloses the loose nail of the cement preventing from loosening, be made up of the head of a nail, nail bar and nail tip, the head of a nail is one-body molded in nail bar upper end, nail tip is integrally made in nail bar lower end, and have arc anti-rotation groove (4) in the direction that hammers into of nail bar, the curve bath radian of anti-rotation groove (4) is greater than 180 degree, the curve bath of anti-rotation groove and the wedge angle rounding of the periphery intersection of nail bar, this pin structure is simple, penetrating power strong, especially effectively can prevent loosening of cement nail, improve the safety and reliability of use.
Description
Technical field
The utility model belongs to the structural member connection area of nail, is particularly applied to and the nail being connected cement components.
Background technique
Cement nail is generally made up of the head of a nail, nail bar and nail tip, the head of a nail is one-body molded in nail bar upper end, nail tip is integrally made in nail bar lower end, cement nail is mainly used in construction industry, when portland cement nail injects cement wall surface by pneumatic nail gun, due to the composition of cement and the difference of ratio, often there is nail phenomenon loosely, qualitative problems of construction in various degree can be caused.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided the cement preventing from loosening loose nail, this pin structure is simple, penetrating power is strong, effectively prevent loosening of cement nail, the utility model solves its technical problem and takes following technological scheme to realize: prevent the loose nail of cement loosened, by the head of a nail, nail bar and nail tip are formed, the head of a nail is one-body molded in nail bar upper end, nail tip is integrally made in nail bar lower end, arc anti-rotation groove is had in the direction that hammers into of nail bar, the curve bath radian of anti-rotation groove is greater than 180 degree, the curve bath of anti-rotation groove and the wedge angle rounding of the periphery intersection of nail bar, material selection No. 55 steel.Advantage of the present utility model and good effect are: this pin structure is simple, penetrating power strong, especially effectively can prevent loosening of cement nail, improve the safety and reliability of use.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the sectional view of nail bar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: prevent the loose nail of cement loosened, as depicted in figs. 1 and 2, by the head of a nail (1), nail bar (2) and nail tip (3) are formed, the head of a nail (1) is one-body molded in nail bar (2) upper end, nail tip (3) is integrally made in nail bar (2) lower end, material selection No. 55 steel, when cement nail penetrates people's metope by nail gun, the direction that hammers into of nail bar has arc anti-rotation groove (4) effectively can prevent cement loose nail loose or dislocation, the curve bath radian of anti-rotation groove (4) is greater than 180 degree, the curve bath of anti-rotation groove (4) and the wedge angle rounding of the periphery intersection of nail bar (2), so advantageously enter metope in cement nail.
It should be noted that; anti-rotation groove described in the utility model (4) embodiment is illustrative; instead of it is determinate; the anti-rotation mode of every other analogous shape drawn on nail bar (2) direction according to the technical solution of the utility model by those skilled in the art, belongs to the scope of the utility model protection equally.
