Double-cap steel nail

Abstract

A double-cap steel nail belongs to the technical field of steel nails. The nail cap is divided into the inner cap and the outer cap, during use, the nail body is knocked into a material by striking the outer cap, so that the inner cap is in contact with the material, and when disassembly is needed, a tool can be directly used for fixing the outer cap, so that the nail body is easily pulled out of the material without damaging a material body; the nail body can be quickly taken out from the material while the material is protected, so that the dismounting time is saved, and a large amount of labor is saved.

Description

TECHNICAL FIELD

[0001] The utility model belongs to steel nail technical field, specifically relates to a double cap steel nail. BACKGROUND

[0002] The quantity of nails is very big on the construction site, if the formwork is assembled into the mould, the mould is frequently disassembled, and the labour intensity is big. The common nail is very difficult to disassemble after being nailed on the mould, and the time is wasted, and the disassembled nail can be used again. In addition, the wood such as board or batten is damaged in the process of disassembling, and the waste of material is serious, so a kind of nail is very needed, which is firmly nailed and not easy to be pulled up, protects material and saves time. SUMMARY

[0003] The utility model mainly solves the technical problems of the prior art, and provides a double cap steel nail.

[0004] The above technical problems of the utility model are mainly solved by the following technical scheme: a double cap steel nail, the nail includes nail body and nail cap, and the nail cap is arranged at the upper end of the nail body, and the nail cap is characterized by: the nail cap includes outer cap and inner cap, the outer cap and the inner cap are arranged at the top of the nail body with interval, the edge section of the outer cap and the inner cap is circular, and the edge and the upper and lower surfaces are all tangent to the transition of circular arc.

[0005] Preferably, the overall length of the nail body is 10CM-10.5CM, and the bottom is diamond structure.

[0006] Preferably, the interval between the outer cap and the inner cap is 8CM-1.5CM.

[0007] Preferably, the diameter of the nail cap is 0.5CM-0.8CM.

[0008] The utility model has the beneficial effects that: the nail cap is provided with inner cap and outer cap, when in use, the outer cap is struck to knock the nail body into the material, so that the inner cap contacts the material, when disassembling, the outer cap can be directly fixed by using a tool, the nail body can be easily pulled out from the material, the material body does not need to be damaged, the material itself can be protected, the nail body can be quickly taken out from the material to save disassembling time and a large amount of labor.
