The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, the embodiment of the double-headed nail for installation without nail hole suitable for decorative materials includes a body 1, a limiting portion 2 protrudes from the middle of the body 1, the limiting portion 2 divides the body 1 into a first nail 3 and a second nail 4, the front ends of the first nail 3 and the second nail 4 are both set to be sharp corners, and the outer surfaces of the first nail 3 and the second nail 4 are both provided with a plurality of layers of barbs 5.

1) The invention realizes the wall-mounted decoration material without exposing nail holes by changing the structure of the nail and adopting a mode of two-head nailing without changing the mounting condition of the traditional headless steel nail, and specifically comprises the following steps: no. two nails 4 can be nailed into wall body or mounting panel etc. on, can nail into other panels etc. on No. 3, want to install panel on wall or mounting panel at last, have stealthy installation function, do not expose the nail hole, do not leave advantages such as scar.

2) As shown in fig. 2, can utilize the supporting circular steel cylinder cover 6 cover of customization to form and strike the position temporarily on the double-end nail, strike steel cylinder cover 6 and accomplish one end of nail 4 and beat and get into the wall body or other positions that need be fixed on, take off the ornamental material that the sleeve will need to be fixed, nail on nail 3 from the back like the skirting line, accomplish ornamental material's fixed mounting to not revealing the nail hole, it is very practical, seem simple, its structure is ingenious in fact, difficult thinking, the structure innovation.

3) When the double-headed nail is designed, the first nail 3 and the second nail 4 are additionally provided with the inverted tooth (barb) design, so that the nail holding performance of the double-headed nail on decorative materials is stronger, and the double-headed nail is firm in structure after installation.

4) As shown in fig. 1, the dimensional marks of the components of the present application are included, and this is only a specific preferred embodiment of the design solution of the present application, and the dimensions can be adjusted according to practical situations, and the specific dimensions of the present solution are described as follows: the length of 1 overall length 31mm of body, No. 3, No. 4 nails is 10mm, 19.4mm respectively for a nail, and 2 whole thickness in spacing portion are 1.6mm, and wherein the right-hand member face is in the tilt state, and right-hand member face thickness is 0.6mm, and 2 width (diameters) in spacing portion are 4mm, and No. 3, No. 4 nail width (diameters) are 2.6mm for a nail, above-mentioned when involving the diameter description, its cross section that all represents the part is circular.

In a preferred embodiment, the barbs 5 on the first nail 3 are inclined towards the limiting part 2, and the barbs 5 on the second nail 4 are inclined towards the limiting part 2 to form a pawl structure, so that the nail-holding performance of the decorative material is stronger, and the structure is firm after installation.

In a preferred embodiment, the multi-layer barbs 5 on the nail 3 and the multi-layer barbs 5 on the nail 4 both form the anti-falling parts, the left end of the anti-falling part on the nail 3 is close to the sharp corner of the nail 3, the anti-falling part on the nail 4 is located in the middle of the nail 4, and the left end of the anti-falling part on the nail 3 is close to the sharp corner of the nail 3, so that the decorative plate can be quickly pre-fixed (i.e., a material required to be fixed).

In a preferable embodiment mode, the left end face of the limiting part 2 is a plane perpendicular to the first nail 3, so that the steel cylinder sleeve 6 is convenient to use in a matching manner; the contained angle is greater than 90 degrees between 2 right-hand members of spacing portion and No. two nails 4, and similar traditional steel nail inclined plane or arcwall face transition are also convenient for structurally follow closely No. two nails 4 into on wall body or other needs fixed positions.

In a preferred embodiment mode, the longitudinal sections of the sharp corners of the first nail 3 are all in a first triangle, and the vertex angle of the first triangle is 45 degrees, which belongs to a preferred angle.

In a preferred embodiment, the longitudinal sections of the sharp corners of the second nails 4 are both in a second triangle, and the vertex angle of the second triangle is 30 degrees, which is a preferred angle.

The first nail 3, the second nail 4 and the limiting part 2 are integrally formed, so that the structure is firm, the strength is high, and batch production is facilitated.

In a preferred embodiment mode, the length of the first nail 3 is less than that of the second nail 4, which is a preferred mode, the first nail 3 fixes some decorative plates (i.e. materials to be fixed) with a length less than that of the first nail 3, so as to realize a hidden fixing effect, if the length of the first nail 3 is greater than that of the second nail 4, but objects with large volume and heavy weight are easily fixed by the first nail 3, at the moment, because the second nail 4 is shorter than the first nail 3, the firmness of the second nail 4 after being nailed into the wall body can not be matched with the objects fixed on the first nail 3, so that the second nail 4 is separated from the wall body, the width (diameter) of the first nail 3 and the width (diameter) of the second nail 4 are preferably the same, and can be adjusted and changed according to actual needs, for example, the width (diameter) of the first nail 3 is smaller than the width (diameter) of the second nail 4.

Finally, it should be noted that the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
