Abstract
The utility model relates to a quick tapping screw, which belongs to fastening nails and is composed of a nail head and a nail rod. The nail bar is provided with three or four screw-thread screw grooves, and the nail head can be made to quadrate or orthohexagon, when the nail head is forced, the nail bar enters rotatablely, which is suitable for the fastening of the wood, the bricks and the cements, can replace the prior nails, wood screws, and expansion bolts, and has the advantages of light weight, saving steel product, large stiffness and fastening.
Description
The utility model belongs to fastening piece nail class.
Existing garden nail is made up of the sliding nail bar of the head of a nail and garden, and the nail bar is a smooth garden cylindricality, and the frictional force on surface is less, deviates among the Yi Congmu, and fastening piece is firm inadequately, and this garden nail more is unsuitable for carrying out in brick and cement fastening.
The purpose of this utility model is: provide a kind of frictional force big, not only be suitable in wooden fasteningly, and be suitable for quick attack screw fastening in brick and cement.
Technical measures of the present utility model are: based on the existing garden nail of being made up of the head of a nail and nail bar; On the nail bar, be processed with 3-4 spiral chute.
Quick attack screw of the present utility model, after the head of a nail application of force, the nail bar enters while rotating; Thin can replace existing garden nail, wood screw; Thick can replace EXPANSION ANCHOR BOLTS; Can be suitable in wooden, brick and the cement fastening; Good effect that so this quick attack screw has is widely applicable, save steel, rigidity is big, fastening force is big.
Accompanying drawing is a structural representation of the present utility model.
1 is the head of a nail among the figure; The 2nd, the nail bar; The utility model is to be processed with 3-4 spiral chute on the nail bar, is twisted shape; Thin this screw can replace existing garden nail and wood screw; Thick this screw can have now and EXPANSION ANCHOR BOLTS for topic; This screw is during to the nut application of force, and nail bar 2 enters while rotate, is applicable to fastening in wooden, brick and the cement, because screw rod is twisted shape, surface area is big, frictional force also just greatly, so fastening comparatively firm.This screw also has the characteristics that rigidity is big, in light weight, save steel.Take out for convenience fastening back, and the head of a nail can add quadrate or orthohexagonal.
Claims (2)
1, a kind of quick attack screw is made up of the head of a nail, nail bar, it is characterized in that: on the nail bar 3-4 spiral chute arranged.
2, by the described screw of claim 1, it is characterized in that: the head of a nail is foursquare or orthohexagonal.
