Abstract
The utility model relates to ring grain nail technical field, especially relates to a kind of Pagoda-shaped ring grain nail.Be characterized in comprising newel, be provided with the head of a nail above described newel, below newel, be provided with nail tip, newel is provided with many ring grains through thread rolling processing, is formed every post between every two ring grains.Its ring grain is arranged with the combination every post, the expansion coefficient of nail is increased, the i.e. nail of same model, need raw material wire diameter comparatively before wire diameter thin, so can save the material of about 20%, the raw material of identical wire diameter, the nail newel rubbed is thicker, external diameter becomes large, and the resistance to flexure of nail like this increases; On the other hand, because ring grain is large with the surface area every column combination, the area retaining wood when nail hammers in wood is large, and the binding ability of nail like this and wood strengthens, and namely tensile strength increases; The utility model reasonable in design, saves material, and tensile strength and resistance to flexure increase greatly.
Description
Technical field
The utility model relates to ring grain nail technical field, especially relates to a kind of Pagoda-shaped ring grain nail.
Background technique
Ring grain nail is the ringwise nail of a kind of tooth form.It is thicker that the ring grain fixing model in the market follows closely the raw material wire diameter adopted, ring grain is all del, so, rub the nail expansion coefficient come little, newel is too thin, cause the resistance to flexure of nail little, and waste raw material, because the ring grain surface area of inverted triangle is little, the area retaining wood during work is little, cause the combination force of nail and wood weak, tensile strength is little.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of Pagoda-shaped ring grain to follow closely, thus effectively solves the defect existed in prior art.
For achieving the above object, the technological scheme that the utility model is taked is: described Pagoda-shaped ring grain nail, be characterized in comprising newel, the head of a nail is provided with above described newel, nail tip is provided with below newel, newel is provided with many ring grains through thread rolling processing, is formed every post between every two ring grains.
Described ring grain forms inverted pyramidal structure with every column combination entirety, and ring grain is inverted truncated cone.
Included angle A between the conical surface of described ring grain and horizontal plane is 20-60 degree.
The tapering of the conical surface of described ring grain is 1: 0.6-1: 0.4.
The beneficial effects of the utility model are: described Pagoda-shaped ring grain nail, its ring grain is arranged with the combination every post, the expansion coefficient of nail is increased, the i.e. nail of same model, the raw material wire diameter of needs comparatively before wire diameter thin, so can save the material of about 20%, the raw material of identical wire diameter, the nail newel rubbed is thicker, and external diameter becomes large, and the resistance to flexure of nail like this increases; On the other hand, because ring grain is large with the surface area every column combination, the area retaining wood when nail hammers in wood is large, and the binding ability of nail like this and wood strengthens, and namely tensile strength increases; The utility model reasonable in design, saves material, and tensile strength and resistance to flexure increase greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural principle schematic diagram;
Fig. 2 is axle geodesic structure schematic diagram of the present utility model.
Shown in figure: 1. newel, the 2. head of a nail, 3. nail tip, 4. ring grain, the 4-1. conical surface, 5. every post.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, described Pagoda-shaped ring grain nail, is characterized in comprising newel 1, the head of a nail 2 is provided with above described newel 1, be provided with nail tip 3 below newel 1, newel 1 be provided with many ring grains 4 through thread rolling processing, formed every post 5 between every two ring grains 4.
Further, described ring grain 4 with form inverted pyramidal structure every post 5 composite entity, ring grain 4 is inverted truncated cone.
Further, the included angle A between the conical surface 4-1 of described ring grain 4 and horizontal plane is 20-60 degree.
Further, the tapering of the conical surface 4-1 of described ring grain 4 is 1: 0.6-1: 0.4.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
