Abstract

The utility model discloses a combined type nail comprising a nail body and a cap, wherein, nail points are arranged at two ends of the nail body, an outward projecting spacing ring is arranged at the middle part of the nail body, the cap is sleeved at one end of the nail body for withstanding external force accompanying the driving of the other end of the nail body, a cone-shaped inner chamber matched with the nail points in outer contour is arranged in the cap, a protection cavity is arranged the tip part of the cone-shaped inner chamber in an outward sinking manner, and a positioning cavity matched with the nail body in outside diameter extends outward from the tail part of the cone-shaped inner chamber. The nail points arranged at the two ends of the nail body serve to facilitate connection between wood boards, and can ensure that no traces of the nail are left on the surfaces of the wood boards in the wake of the connection, thereby improving aesthetically pleasing effect. The cap facilitates initial driving of the nail, thereby improving the practicality of the nail.

Description

A kind of combined type nail

Technical field

The utility model relates to a kind of combined type nail.

Background technique

It is the structure of the head of a nail for nail point, an end that existing nail is an end, and after nail hammered into plank, the head of a nail was all exposed outside, influences attractive in appearance.And the phenomenon of stressed bending takes place in the limited length of nail, long nail through regular meeting in hammering into process.When the length of nail during less than the thickness of plank, nail can not be used for two plank ground and connect, and the nail of existing structure has limited its using scope, and daily life is made troubles.

The model utility content

At the problem that existing situation exists, the purpose of this utility model is to provide a kind of simple in structure, the combined type nail that all there is the nail point at two ends.

For achieving the above object, a kind of combined type nail of the utility model comprises nail body and cap, and wherein the two ends of nail body are provided with the nail point, also are provided with the spacer ring that outwards is convexly equipped with on the intermediate portion of nail body; Cap is sleeved on the end of nail body; extraneous power when being used to bear the nail body the other end and hammering into; be provided with and follow closely the suitable conical internal cavity of sharp external frame in the cap; the top tip part of this conical internal cavity outwards is concaved with the protection chamber, and the afterbody of conical internal cavity also is outward extended with and the suitable positioning chamber of the external diameter of nail body.

The utility model has made things convenient for the connection between the plank, and can not leave the vestige of nail on the surface of plank by the nail point all is set on the two ends of nail body, has improved aesthetic.By the configuration block, made things convenient for initially hammering into of nail, improved its practicability.
