Abstract

The utility model provides a barbed nail, which comprises a nail point, a nail body and a nail cap, wherein, a plurality of axially distributed edge strips are made on the surface of the nail body, a plurality of wedged barbs towards the nail point are made on the edge strips, barbs are uniformly arranged on the edge strips, and the edge strips, the barb and the nail body are an integral structure. Since the barbs are made on the nail body, after the nail is nailed in an object, wood fibers are embedded among barbs, the nail retention force is greatly increased, the nail is difficult to pull out, and the fixing force applied on the object is increased. Since the barbs are made on the edge strips, the barbs can be formed through rubbing process after wire drawing and hitting. The utility model has the advantages of simple structure and easiness in manufacture.

Description

Band hangnail nail

Technical field

The utility model relates to the water fastening piece, particularly to the improvement of nail.

Background technique

Present nail is to be formed through cut-out by metal wire rod to follow closely body, and nail body two is made into the head of a nail, followed closely point through pier, and the frictional force between nail dependence self and quilt nail object is in order to fix, to connect object.

In order to obtain bigger frictional force, the nail body of some nail is made twisted shape, and this spiral nail is because the nail body is suppressed with the groove of spiral, nail in wooden object after, in the wood fiber embedded groove, it is stronger nail power.Be applicable to that some are needing the strong place of nail power as drawer, wooden ceiling suspension rod etc.

But because the spiral chute of this nail is similar to fried dough twist, pitch is big, is different from the screw thread of screw, thereby still is pulled out easily when big stressed, big the occasion of nail power of can not satisfying the demand.

The model utility content

The utility model purpose is to provide a kind of big nail of nail power that has hangnail, to satisfy user demand.

Scheme of the present utility model is: band hangnail nail, comprise nail point, nail body, the head of a nail, it is characterized in that: nail body surface is shaped on the rib of many axial distribution, on each rib, be shaped on the wedge hangnail of a plurality of tips towards the nail point, hangnail is evenly arranged on the rib, and rib, hangnail and nail body are overall structures.

The utility model has the advantages that: because nail is shaped on a plurality of hangnails on one's body, nail in object after, wood fiber is embedded between the hangnail, is increasing nail power greatly, makes nail be difficult for being pulled out, and has increased the retention force to object.Because hangnail is on rib, can beat the back by twisting technological forming at wire drawing, pier, the utlity model has advantage simple in structure, easy to manufacture.

Description of drawings

The utility model is described in further detail with embodiment with reference to the accompanying drawings below.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the sectional view of A-A direction among Fig. 1.

Mark among the figure: 1 head of a nail, 2 nail bodies, 3 hangnails, 4 nail points.

Embodiment

In conjunction with Fig. 1 and Fig. 2, embodiment's structure mainly comprises nail point 4, nail body 2, the head of a nail 1.

Nail body 2 surfaces are shaped on the rib of many axial distribution, are to be made by drawing process by wire rod, and present embodiment has four ribs, and quantity can increase and decrease when specifically implementing.

Be shaped on the wedge hangnail 3 of a plurality of tips towards the nail point on each rib, hangnail 3 is evenly arranged on the rib, is that wire rod is after wire drawing, pier are made formation nail body 2, nail point 4, the head of a nail 1, at last by twisting technological forming.

Because rib, hangnail 3 on the nail body 2 are with wire drawing, twist technology with material extruding formation itself, all above-mentioned parts are overall structures with the nail body.

During use, after the nail of band hangnail was followed closely in object, wood fiber was embedded between the hangnail, is increasing nail power greatly, makes nail be difficult for being pulled out, and has increased the retention force to object.

Claims

1. be with the hangnail nail, comprise nail point (4), nail body (2), the head of a nail (1), it is characterized in that: nail body (2) surface is shaped on the rib of many axial distribution, on each rib, be shaped on the wedge hangnail (3) of a plurality of tips towards the nail point, hangnail (3) is evenly arranged on the rib, and rib, hangnail (3) are overall structures with nail body (2).
