A nail with conical barbs is mainly composed of a nail cap (1), a nail body (2), conical barbs (3) and a nail tip (4), wherein three rows of conical barbs are arranged on the surface of the nail body (2) in the length direction, the conical barbs are axially staggered and orderly distributed, the conical barb is composed of a cone tip (31), a cone back (32), a cone abdomen (33) and a cone base (34), and the cone tip (31) points at the nail cap (1). The utility model has the advantages of firmer connection, durability, safety, simple structure and low manufacturing cost.

Description

The nail that has the back taper thorn

Technical field

The utility model relates to a kind of nail, especially follows closely the nail that body is provided with the back taper thorn.

Background technique

Nail (the iron that generally uses on the current social, steel, alloy) most of nail body is a polished rod, a frictionally clenched when this nail combined with quilt nail object, in conjunction with firm inadequately, fastening force is little, especially can reduce join strength and working life when the object surface of contact combines situation and changes with being followed closely when the nail body, even bring hidden danger.For this reason, on the structure of nail, improve the design imperative.

Summary of the invention

According to background technique, the purpose of this utility model is to avoid above-mentioned deficiency, provides a kind of and along nail height degree direction triplex row back taper thorn is set, and is dislocation along nail body axis and arranges in order, and its awl point points to the nail that has the back taper thorn of the head of a nail.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of nail that has the back taper thorn, mainly form by the head of a nail (1), nail body (2), back taper thorn (3) and nail point (4), wherein: along the length direction of nail body (2), back taper thorn (3) is set in the L-2D scope, awl point (31) points to the head of a nail (1), surface along nail body (2) is provided with triplex row back taper thorn (3), and along the nail body mutual position angle α in cross section ₃=120 °, back taper thorn (3) is dislocation and arranges in order along nail body (2) axial direction, and wherein L is the length of nail body (2), and D is the profile diameter of nail body (2); Back taper thorn (3) is by awl point (31), and awl is carried on the back (32), and awl abdomen (33) and awl base (34) are formed, and bores the angle α of the back of the body (32) with respect to nail body (2) axis ₁=30 °, awl abdomen (33) is with respect to the angle α of nail body (2) axis ₂=52 °, awl base (34) intersects the pairing chord length C=D/3 of arc length with nail body (2) outer surface.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, it is more firm that the utility model can make connection, durable, and safety can adapt to the variation of connected body physical property, especially can be used for wooden connection more easily.

2, the utility model is simple in structure, and is cheap.
