Abstract
The invention relates to a novel screw. The novel screw comprises a screw head, a screw rod and a screw point, all of which are arranged integrally. The screw head and the screw point are arranged at the two ends of the screw rod respectively. The screw rod comprises a large end and a small end. The screw head is arranged at the large end of the screw rod, and the screw point is arranged at the small end of the screw rod. The diameter of the cross section, from the large end to the small end, of the screw rod is gradually decreased. An external thread is arranged on the outer wall of the screw rod. The screw point is a cone. The screw head is of a regular polygon structure. According to the novel screw, the outer wall of the screw rod is arranged to be an arc face, that is, the diameter of the cross section, from the large end to the small end, of the screw rod is gradually decreased, so that the resistance in the screwing process of the screw is the minimum, and screwing-in of the screw is facilitated.
Description
Technical field
The present invention relates to a kind of fastening piece, be specifically related to a kind of novel screw.
Background technique
Screw is a kind of fastening piece conventional in daily life and industry, can be good at playing connection function according to the structural feature of self.But, when the tapped hole that used screw is made up of wood materials over there, because wood materials self has certain stretchability, the tapped hole offered can reduce, if tapped hole likely can swallow up by time length, screw rod, in the process of screwing, is difficult to enter in tapped hole.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of novel screw.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of novel screw, comprise and all-in-one-piece screw head, nail bar and nail tip are set, described screw head and nail tip are separately positioned on the two ends of nail bar, described nail bar comprises stub end and little head end, described screw head is arranged on the stub end of described nail bar, described nail tip is arranged on the little head end of described nail bar, and the diameter of described nail bar from stub end to the cross section of little head end reduces successively; Described nail bar outer wall is provided with outside thread; Described nail tip is cone; Described screw head is positive shape changeable structure.
The invention has the beneficial effects as follows: novel screw of the present invention is arranged to a cambered surface screw rod outer wall, namely follow closely bar and reduce successively from stub end to the cross-sectional diameter of little head end, make the resistance of screw in the process of screwing reach minimum, facilitate the precession of screw.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described externally threaded cross section is square.
Further, the upper surface of described screw head is provided with interior hexagonal counterbore.
Further, described screw is made up of low intensive nonferrous material.
Further, described screw material comprises at least one of aluminium or magnesium.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment novel screw.
In accompanying drawing, the list of parts representated by each label is as follows:
1, screw head; 2, bar is followed closely; 21, stub end; 22, little head end; 23, outside thread; 3, nail tip.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of novel screw, screw is made up of low intensive nonferrous material, and screw material comprises at least one of aluminium or magnesium; Bolt structure comprises and arranges all-in-one-piece screw head 1, nail bar 2 and nail tip 3, screw head 1 and nail tip 3 are separately positioned on the two ends of nail bar 2, nail bar 2 comprises stub end 21 and little head end 22, screw head 1 is arranged on the stub end 21 of nail bar 2, nail tip 3 is arranged on the little head end 22 of nail bar 2, and the diameter of nail bar 2 from stub end 21 to the cross section of little head end 22 reduces successively; Nail bar 2 outer wall is provided with outside thread 23, and the cross section of outside thread 23 is square.Nail tip 3 is cone; Screw head 1 is positive shape changeable structure, and the upper surface of screw head 1 is provided with interior hexagonal counterbore.
The novel screw of the present embodiment is arranged to a cambered surface screw rod outer wall, namely follows closely bar and reduces successively from stub end to the cross-sectional diameter of little head end, make the resistance of screw in the process of screwing reach minimum, facilitate the precession of screw.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
