Embodiment Construction

[0013] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0014] Examples, see figure 1 As shown: a multi-segment anti-cracking nail, including a nail head 11, and the lower end of the nail head 11 is provided with a conical bottom groove 111. That is, the nail tip is formed by the bottom edge of the tapered bottom groove 111 . In this way, when the nail head 11 enters the wooden material, the extrusion force on the wooden material is directed from the outside of the nail head 11 to the axis of the nail head 11, which reduces the probability of the wooden material cracking. At the same time, the upper end of the nail head 11 is integrally connected with a first thickening section 12 , and the lower end surface of the first thickening section 12 is provided with an annular tapered groove 20 . The so-called annular tapered groove 20 means that the cross section of the a...

Abstract

The invention discloses a multi-segment anti-cracking nail, which comprises a nail head, wherein a conical bottom groove is arranged on the lower end of the nail head, and meanwhile, the upper end of the nail head is integrally connected with a first thickening segment, and an annular taper groove is arranged on the lower end face of the first thickening segment. After optimization, the upper end of the first thickening segment is integrally connected with a second thickening segment, and an annular taper groove is arranged on the lower end face of the second thickening segment; and a diameter D of the nail head is not more than 2 mm. The invention has the advantages of simple structure and easiness in preparation.

Description

technical field [0001] The invention relates to the technical field of metal products, in particular to a multi-segment anti-split nail. Background technique [0002] When a nail is nailed to a wood material that is less flexible, the wood material is very prone to splintering. For this reason, anti-cracking nails have appeared. However, most anti-cracking nails have complicated structures and complicated preparations. Therefore it is necessary to improve it. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a multi-segment anti-split nail, which has the characteristics of simple structure and easy preparation. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a multi-segment anti-split nail, including a nail head, the lower end of the nail head is provided with a tapered bottom groove, and at the same time, the upper ...
