Abstract
The utility model relates to a novel self-locking steel nail formed by rolling and compacting good quality steel. The utility model is characterized in that the tip of the nail is in the shape of a cone, wherein the diameter of the bottom of the cone is smaller than that of a nail cap and is larger than that of a nail rod. The surface of the entire nail is coated with a layer of unattacked rare earth aluminium alloy. The utility model has bending resistance performance, self-locking performance and unattacked and rustproof performance, can replace imported nails, stainless steel nails, aluminium alloy nails and copper alloy nails, can also be made into a novel self-locking shoot nail, and enables hardware fasteners of China to be upgraded and developed. The technical scheme of the utility model is suitable for volume-producing novel nails to be exported to earn foreign currency.
Description
The utility model self-locking steel nail belongs to the hardware fastener technology and issues the territory, is suitable for industries such as modern packaging, communications and transportation, furniture, shoemaking and building and uses.
Tradition hardware fastening piece " nail " is to make by wire drawing controlling nail technology with the low carbon steel wire rod, zinc-plated, the ungalvanized that has that have.Along with modern industry communications and transportation high speed development, international trade and long-distance transport are prosperous day by day, but " nail " exposes major defect in industry practice such as modern packaging, communications and transportation: the one, and the poor rigidity anti-bending strength is low, and crooked scrappages such as nail system book sheet metal, hard miscellaneous tree, polymeric material are high especially; The 2nd, " nail " lock ability is poor, as with " nail " nail packaging box, should select big specification nail for use, and dense again cloth nail just can reach light-duty packaging box requirement, if the case accident of loosing then very easily takes place nail system heavy wrapping case; The 3rd, " nail " abrasion-proof corrosion-proof is poor, as with very easily wearing and tearing, the corrosion and come off of " nail " nail system high-heel shoes, no matter zinc-plated or not zinc-plated " nail " is not wear-resisting.Therefore modern furniture is many need not " nail " and use expensive stainless steel nail, aluminum alloy nail and Cuprum alloy nail instead.It is imperative to this shows that the development of new nail replaces " nail ".
The purpose of this utility model just provides a kind of novel self-locking steel nail, can replace backward " nail " and expensive stainless steel nail, aluminum alloy nail, Cuprum alloy nail.As shown in drawings.Its technical characteristics is: it is molded to select for use the high-quality steel wire rod to prick, and its nail point (1) be conical, conical bottom diameter (2) less than circular head of a nail diameter (3) again greater than following closely shank diameter (4); Surperficial plating 0.3 to the 0.5mm rare earth aluminium alloy dress of full nail metal plate protective layer.
The method of using novel self-locking steel nail is about to follow closely the body perpendicular alignmnet and is followed closely object with identical with " nail ", firmly suppresses the head of a nail.After being surpassed its compressive strength, both to nail point (1) inflated around and resiliently deformable, resiliently deformable again to hammering into the direction bending by nail object (as timber, bamboo wood, plastics, book sheet metal, polymeric material etc.) the sharp stamping press of suffered nail; After the sharp conical bottom of nail (2) is passed through, followed closely the partly automatic resilience of resiliently deformable of object and surrounded nail bar (4); When the circular head of a nail (3) by after touching and compressing by the nail body surface, the resiliently deformable of follow closely object partly automatically resilience be full of and follow closely bar (4) space on every side, and tight double team nail bar (4).Therefore follow closely bar (4) and be enclosed in by in the nail object, can not readvance, can not draw back again, thereby will firmly be connected into integral body by the nail object more than two by conical bottom (2) and the circular head of a nail (3) auto lock.
The advantage of this novel self-locking steel nail is: 1, molded owing to selecting for use the high-quality steel wire rod to prick, and better than the big anti-bending strength of low carbon steel " nail " rigidity, can hammer into book sheet metal, hard frame wood, polymeric material etc., and crooked scrappage is low; 2, the auto lock ability of novel self-locking steel nail is considerably beyond " nail ", even near the rivet level, can prevent to vibrate pine and move back with the Bales Off accident and take place; 3, novel self-locking steel nail resistance to tension is strong, uses the new sprig identical with " nail " stretching resistance then can reduce new sprig steel using amount, or uses the new sprig with " nail " identical weight then can reduce new sprig quantity; 4, novel self-locking steel nail surface plating 0.3 to 0.5mm rare earth aluminium alloy, the dress metal plate protective layer that is silvery white in color than 15 times of zinc-plated " nail " abrasion-proof corrosion-proofs, therefore both can replace " nail ", can replace stainless steel nail, aluminum alloy nail and Cuprum alloy nail again.
Because the domestic production and supply in a large number of the used raw material of novel self-locking steel nail, the efficient pressure equipment of pricking domesticizes, this novel self-locking steel nail shape is simpler than novel drive screw in addition, therefore the mechanician just can implement the utility model self-locking steel nail by the conventional design means, help producing in enormous quantities novel self-locking steel nail series product, replace " nail " series product, realize that the hardware fastening piece updates.
Claims (2)
1, a kind of novel self-locking steel nail is characterized in that pricking molded with the high-quality steel.Its nail point is a taper, the garden cone bottom diameter less than head of a nail diameter again greater than following closely shank diameter; The surperficial plating one deck rare earth aluminium alloy of full nail.
2,, it is characterized in that the corrosion resistant rare earth aluminium alloy of comprehensive plating one deck according to the surface of the described novel self-locking steel nail of claim 1.
