Abstract
The utility model discloses a strengthening type decorative screw which comprises a nut and a threaded rod arranged below the nut. A cross-shaped driving groove is formed in the upper end face of the nut. Threads are arranged on the threaded rod. A plurality of concave pits which are vertically and horizontally arranged in a staggering and side-by-side mode are formed in the upper end face of the nut. A plurality of strengthening ribs with right-triangle-shaped cross sections are connected between the nut and the threaded rod. Two right-angle sides of each strengthening rib are respectively and fixedly connected with the lower end face of the nut and the side wall of the threaded rod. A transverse through hole is formed in the center position of the lateral side of each strengthening rib. Due to the fact hat the concave pits which are vertically and horizontally arranged in the staggering mode are formed in the upper end face of the nut, coating and paint can be easily attached to concave-convex surfaces, decorative effects on wall surfaces and a ceiling are strengthened, due to additional arrangement of the strengthening ribs with transverse through holes, people can enable the plurality of screws to be mutually connected by using a metal wire to penetrate through the transverse through holes, looseness of single screw is avoided, and stability is strong.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of reinforced Decorative screw.
Background technique
Many objects screw commonly used fixes, and present screw is made of the screw rod of nut and nut below, is provided with driver slot in the upper-end surface of nut, screw rod is provided with screw thread, act in the driver slot by screw-driver during installation, provide rotating force to screw rod, thereby screw in target object.When utilizing many screws to fix a plane, effectively do not connect between many screws, often loosening; And the nut surface of existing screw all is smooth flat, when hammering into ceiling board or metope, in case ceiling board or metope need paint coating or paint, often owing to can not be attached on the smooth surface of screw, whole like this metope can expose the nut surface of screw, ornamental reduction greatly.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of reinforced Decorative screw is provided, and it can effectively avoid becoming flexible between the screw connection, and decorative effect strengthens greatly.
The technological scheme that the utility model adopts is: a kind of reinforced Decorative screw, the screw rod that comprises nut and nut below, the upper-end surface of described nut is provided with the cross driver slot, described screw rod is provided with screw thread, the upper-end surface of described nut is provided with the staggered pit side by side of some cross types, be connected with the stiffening rib that a plurality of cross sections are right-angled triangle between described nut and the screw rod, two right angle sides of described stiffening rib are fixedly connected with the lower end surface of nut and the sidewall of screw rod respectively, and the central position, side of described stiffening rib is provided with cross through hole.
As preferably, the longitudinal profile of described pit is V-shaped.
As preferably, described stiffening rib has four, evenly distributes along the sidewall circumferencial direction of described screw rod.
The beneficial effects of the utility model are: because the utility model arranges crisscross pit in the nut upper-end surface, make the nut upper-end surface form male and fomale(M﹠F), the coating that whitewashes and paint etc. increase with the surface of contact of male and fomale(M﹠F), coating and easier being attached on the male and fomale(M﹠F) of paint have strengthened the decorative effect of metope and ceiling board; And set up the stiffening rib of band cross through hole, and people can utilize wire to pass cross through hole to interconnect with fixing conplane many screws, have avoided the loosening of single screw, and stability is stronger.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the nut plan view.
Among the figure: 1, nut; 2, screw rod; 3, cross driver slot; 4, pit; 5, stiffening rib; 6, cross through hole.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of reinforced Decorative screw, the screw rod 2 that comprises nut 1 and nut 1 below, the upper-end surface of described nut 1 is provided with cross driver slot 3, described screw rod 2 is provided with screw thread, the upper-end surface of described nut 1 is provided with the staggered pit 4 side by side of some cross types, the longitudinal profile of described pit 4 is V-shaped, being connected with a plurality of cross sections between described nut 1 and the screw rod 2 is the stiffening rib 5 of right-angled triangle, described stiffening rib 5 has four, sidewall circumferencial direction along described screw rod 2 evenly distributes, two right angle sides of described stiffening rib 5 are fixedly connected with the lower end surface of nut 1 and the sidewall of screw rod 2 respectively, and the central position, side of described stiffening rib 5 is provided with cross through hole 6.
Because the utility model arranges crisscross pit 4 in nut 1 upper-end surface, make nut 1 upper-end surface form male and fomale(M﹠F), the surface of contact of the coating that whitewashes and paint etc. and male and fomale(M﹠F) increases, and coating and easier being attached on the male and fomale(M﹠F) of paint have strengthened the decorative effect of metope and ceiling board; And set up the stiffening rib 5 of band cross through hole 6, and people can utilize wire to pass cross through hole 6 to interconnect with fixing conplane many screws, have avoided the loosening of single screw, and stability is stronger.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
