Specific embodiment
A kind of Decorative screw component of the invention adopts the following technical scheme that: as shown in Figs 1-4, Decorative screw component packet
Decorative screw 1 and bolt decoration cover 2 are included, Decorative screw 1 includes rivet nut 11, and 11 outer surface of rivet nut is provided with external screw thread, rivet nut 11
Partial external screw thread is prior art content, is repeated no more.The upper end of rivet nut 11 has ailhead, the head of a nail with the head of a nail 12, lower end
12 be the existing common taper head of a nail 12, and the cylindrical head of a nail 12 can also be used, be that the prior art repeats no more.Rivet nut is full spiral shell
Line, head center point have deep hole.The upper end of the head of a nail 12 has for screwing groove 121 for screw driver, screws groove 121
For existing common "-" type or cross or rice font, in order to which screwdriver or dedicated screw screwing-up tool screw screw,
The center for screwing groove 121 is equipped with the blind hole 122 extended along the axis direction of rivet nut 11, and the length of blind hole 122 screws groove certainly
121 bottom surface extends downwardly, and the bottom hole 1221 of blind hole 122 root apart from the head of a nail 12 120 1 set distance, set distance is not
Lower than 2mm, depending on specific distance needs to refer to the length of screw, under normal circumstances, the depth of blind hole 122 should be ensured that its blind hole
The ailhead a certain distance of 122 low side apart from screw, to guarantee the intensity of screw；Meanwhile the depth and grafting of blind hole 122
The length of column 22 is also contemplated that subject to inserting column 22 is inserted into blind hole 122 and is not easy to loosen, in the present embodiment, the bottom of blind hole 122
Ailhead of the identity distance from screw at least 3mm, with a distance from the head of a nail 12 at least 2mm of root 120, on the one hand the diameter of blind hole 122 needs root
Depending on the diameter of screw, the diameter of blind hole 122 should guarantee the strong of screw to when young 0.5mm than the minimum diameter of screw
Degree, bolt decoration cover 2 include lid 21, and the upper surface of lid 21 is smooth surface, and it is recessed that the lower end surface of lid 21 is equipped with receiving
Slot 212, the shape of pockets 212 are the combination of lower cylindrical upper spherical, and the diameter of column part is greater than the head of a nail of screw
The depth of 12 outer diameter, pockets 212 (refers to the head of a nail 12 along the length of the axis direction of rivet nut 11 at least equal to the height of the head of a nail 12
Degree) or the depth of pockets 212 be not less than the height of the head of a nail 12, the diameters of pockets 212 is not less than the diameter of the head of a nail 12
The head of a nail 12 is accommodated when to use, the centre of pockets 212 is provided with the inserting column 22 extended downwardly, and inserting column 22 has one
Fixed elasticity, the diameter of inserting column 22 is bigger than the diameter of blind hole 122, and inserting column 22 and blind hole 122 are mating.In order to facilitate grafting
Column 22 can be smoothly inserted into blind hole 122, and the lower end of inserting column 22 and the upper end of blind hole 122 have chamfering 1222, so as to smooth
It is directed into blind hole 122.The material of trim can be the material that plastics, rubber, resin etc. have certain elasticity, can also be
Elastomer is formed after hard the material such as outer surface of ceramics and metal coating elastic material such as plastics, resin and rubber.Blind hole 122 with
And the shape of corresponding inserting column 22 can be cylindrical, prismatic, i.e. the cross-sectional shape of blind hole 122 and inserting column 22 can be with
It is round, polygon and abnormity, and diameter along its length is consistent.
In the present embodiment: the material of inserting column 22 is plastics, and the upper surface of lid 21 is spherical surface 211.It is set in blind hole 122
There is annular groove, inserting column 22 is externally provided with the annular convex platform being correspondingly arranged with annular groove, and annular convex platform and annular groove limit
Cooperation.Further inserting column 22 is made to be not easy to deviate from from blind hole 122.Wherein the shape of the ailhead of screw can be existing
Cone point, cylinder tack and the first-class shape of fluted drill in technology.
Working principle: Decorative screw component includes Decorative screw 1 and bolt decoration cover 2, by the basis of existing screw
The upper processing for carrying out blind hole 122, and the depth of the position and blind hole 122 to blind hole 122 is designed, and forms novel decoration spiral shell
Nail 1, and the corresponding bolt decoration cover 2 of Aided design by the lower section design inserting column 22 in bolt decoration cover 2, and correspond to
Design inserting column 22 size, material so that inserting column 22 with when 122 grafting of blind hole facilitate and it is firm, it is mating
Mode have one by be installed, one draws the convenience that i.e. disassembly is completed, while being slightly larger than blind hole 122 using inserting column 22
Size and inserting column 22 have the characteristics that certain elasticity, so that grafting is closer, are not easy play, and can repeatedly use,
Meanwhile the setting of pockets 212 ensures that 12 part of the head of a nail leaked out except sheet metal or plank can be received groove
212 are accommodated, i.e., the planar section of the lower end surface of bolt decoration cover 2 can paste completely with the outer surface of sheet metal or plank
It closes.
Decoration spiral shell in each embodiment of the specific embodiment of Decorative screw of the invention and above-mentioned Decorative screw component
Each embodiment of nail is identical, repeats no more.
Screw in each embodiment of the specific embodiment of bolt decoration cover of the invention and above-mentioned Decorative screw component
Each embodiment of trim is identical, repeats no more.
