Abstract

The utility model relates to a special shaped nail with barbs. A cross section shape of a nail rod 2 forms a sector, two side lines of the cross section of the nail rod are form concave arcs, and the nail rod is provided with the barb 3. The nail has high strength, good stiffness and small breakage for means, the utility model is not easy to be bent when in service life, the utility model is not easy to exit when the nail is nailed into the means, and the material is saved.

Description

Band hangnail abnormity nail

The utility model belongs to fixed component technical field, particularly nail.

Sight has the nail that uses in the technology mostly to be first nail, crowsfeet and many ribs nail, the garden nail exposes deficiencies such as difficult nail, effort, nail nail easily curved, big to component damage, that hammer into member easily withdraws from application, bring inconvenience to construction, and it is more to make unit's nail consume material; Though crowsfeet and many ribs nail improves to some extent, and remedied some deficiency of first nail, but it is not high intensity to occur, and the nail that hammers into member such as still easily withdraws from disadvantage.

The purpose of this utility model provides a kind of intensity height just in order to solve above-mentioned deficiency, it is curved, little to component damage to be difficult for, be convenient to construct, hammer into and be difficult for withdrawing from and save material, nail that cost is low behind the member.

The purpose of this utility model is achieved by the following technical solution.

Nail of the present utility model its nail bar shape of cross section be fan-shaped, two fan-shaped side lines are the indent camber line, fan-shaped summit can prolong this fan-shaped middle separated time extension or in contract; On nail bar of the present utility model, also have hangnail.

The fan shaped cross section of nail bar of the present utility model, its two side lines that are the indent camber line can symmetry also can be asymmetric.

Because nail bar shape of cross section of the present utility model is that two side lines are the fan-shaped of indent camber line, its cross-section area only is equivalent to 2/3rds of equality strength unit nail sectional area, thereby can save material about 1/3rd, under the prerequisite that consumes the as much material, the intensity of nail, rigidity can strengthen greatly; Resistance was little, not flexible when this kind section configuration also can make nail hammer into member, and little to component damage, was convenient to construction; Two side lines of nail section are when the indent camber line also can make the system nail and are difficult for pulling the wire drawing punch die in drawing process, prevent that mould from bursting apart, and is convenient to processing.Because have hangnail on the nail bar, nail is difficult for withdrawing from after hammering into member, improved the stability of using.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a plan view of the present utility model.

Fig. 2, Fig. 3, Fig. 4, Fig. 5 are several shape figure in the A-A cross section of plan view of the present utility model.

At first make wire drawing punch die on the drawbench, begin the system nail after it is installed according to the shape of the nail that will manufacture and size.

During the system nail, select suitable material for use, draw out system nail silk material on request as steel, plastics etc. on drawbench, the shape of cross section of system nail silk material is that two side lines 4 are the fan-shaped of indent camber line, as shown in Figure 2; This fan-shaped summit o can be along contracting or extension in the fan-shaped middle separated time oo ', as shown in Figure 3, Figure 4; Two fan-shaped side lines 4,4 ' can be along separated time oo ' symmetry wherein, also can be asymmetric, as shown in Figure 5.On nailing maching, will make nail silk material according to the length of making nail then and be cut into segment, pier ailhead 1 on nailing maching again, nailing point 5, leave hangnail 3 with the extruding on nail bar 2 of nail cutter at last and get final product, general every nails on out 1--4 hangnail, has 2 hangnails on the nail bar of present embodiment, hangnail can be opened on the crest line of nail bar, also can open on its fan-shaped cambered surface, every several hangnail that nail on can be opened on the same cambered surface of nail bar or on same crest line, also can open on different crest lines and cambered surface.The hangnail of present embodiment is out on the fan-shaped cambered surface of nail bar.

Claims

1. band hangnail abnormity nail is made up of ailhead 1, nail bar 2, it is characterized in that, (a), the shape of cross section of following closely bar is fan-shaped, fan-shaped two side lines 4 are the indent camber line, fan-shaped summit o can along this fan-shaped middle separated time oo ' extension or in contract; (b) have hangnail 3 on the nail bar 2.

2. band hangnail according to claim 1 abnormity nail is characterized in that, the side line 4 that two of sector crosssection are the indent camber line along in separated time oo ' symmetrical or asymmetric.
