Disk, the first cylindrical body, the second cylindrical body and third cylindrical body tapped through hole, the height of the disk is 0.5mm, disk
Diameter is 6mm, and the height of first cylindrical body is 3 times of disc height, and the diameter of the first cylindrical body is disk diameter
0.6 times, several first strip bulges, first cylindrical body and second are evenly distributed on the periphery wall of first cylindrical body
Annular groove is equipped between cylindrical body, the axial length of the annular groove is 1.5 times of disc height, second cylindrical body
Height be 4 times of disc height, the diameter of the second cylindrical body is 0.7 times of disk diameter, the periphery of second cylindrical body
Several second strip bulges are evenly distributed on wall, the diameter of the third cylindrical body is 0.5 times of disk diameter, third cylinder
The height of body is 3 times of disc height, is evenly equipped with several extensions at the outer wall bottom edge of the third cylindrical body, described to prolong
Extending portion and the outer wall of third cylindrical body are perpendicular, and the height of the extension is 1.5 times of disc height.
Ultrathin notebook computer nut described in the utility model, wherein first strip bulge and the second bar shaped
Protrusion is obliquely installed.
Ultrathin notebook computer nut described in the utility model, wherein the inclined direction of first strip bulge
With the inclined direction of the second strip bulge on the contrary, the angle between first strip bulge and horizontal plane is 110 °, described
Angle between two strip bulges and horizontal plane is 65 °.
Ultrathin notebook computer nut described in the utility model, wherein there are four the extensions, and in fan
Shape.
After using the above structure, compared with prior art, the utility model Ultrathin notebook computer nut has following
Advantage: the utility model is designed by reasonable structure, insertion plastic material part in after, several first strip bulges,
Second strip bulge and extension will greatly increase contact area with plastic part, both improve the compactness of connection；When by
When to slightly larger torsion or shearing force, several first strip bulges, the second strip bulge and extension can prevent this practical new
The rotation of type nut, plays the role of rotation stop；The setting of disk, annular groove and extension plays increase and plastic part table
The effect of face contact area, is equivalent to gasket, it is therefore prevented that jack effect so that the utility model after insertion with plastics
Part connects more firm, has reached good anti-dropout effect.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model Ultrathin notebook computer nut；
Fig. 2 is the present invention looks up structural representation of the utility model Ultrathin notebook computer nut.
Specific embodiment
The utility model Ultrathin notebook computer is made with nut with reference to the accompanying drawings and detailed description further detailed
It describes in detail bright:
As depicted in figs. 1 and 2, in this embodiment, the utility model Ultrathin notebook computer nut, including
The nut body being made of disk 1, the first cylindrical body 8, the second cylindrical body 6 and third cylindrical body 4, disk 1, the first cylindrical body 8,
Second cylindrical body 6 and third cylindrical body 4 are arranged successively from top to bottom, and coaxial line.Offered on nut body through disk 1,
The tapped through hole of first cylindrical body 8, the second cylindrical body 6 and third cylindrical body 4, for being cooperatively connected with bolt or screw rod.Disk 1
Height be 0.5mm, the diameter of disk 1 is 6mm, and the height of the first cylindrical body 8 is 3 times of 1 height of disk, the first cylindrical body 8
Diameter be 0.6 times of disk diameter, be evenly distributed in several first strip bulges 2 on the periphery wall of the first cylindrical body 8.First
Annular groove 7 is equipped between cylindrical body 8 and the second cylindrical body 6, the axial length of annular groove 7 is 1.5 times of 1 height of disk.
The height of second cylindrical body 6 is 4 times of 1 height of disk, and the diameter of the second cylindrical body 6 is 0.7 times of 1 diameter of disk.Second circle
Several second strip bulges 3 are evenly distributed on the periphery wall of cylinder 6, the diameter of third cylindrical body 4 is the 0.5 of 1 diameter of disk
Times, the height of third cylindrical body 4 is 3 times of 1 height of disk.Several prolong is evenly equipped at the outer wall bottom edge of third cylindrical body 4
Extending portion 5, extension 5 and the outer wall of third cylindrical body 4 are perpendicular, and the height of extension 5 is 1.5 times of 1 height of disk.Extension
There are four 5, and it is fan-shaped, anti-dropout effect can be made more preferable.
First strip bulge 2 and the second strip bulge 3 are obliquely installed, and the inclined direction of the first strip bulge 2 and
The inclined directions of two strip bulges 3 is on the contrary, the angle between the first strip bulge 2 and horizontal plane is 110 °, the second strip bulge 3
Angle between horizontal plane is 65 °, and the cross section of the first strip bulge 2 and the second strip bulge 3 is triangular in shape, these knots
Structure can further function as preferable anti-rotation effect.
The utility model is designed by reasonable structure, insertion plastic material part in after, several first bar shapeds are convex
The contact area with plastic part can be greatly increased by playing the 2, second strip bulge 3 and extension 5, improve the close of the two connection
Property；When by slightly larger torsion or shearing force, several first strip bulges 2, the second strip bulge 3 and extension 5 can hinder
The only rotation of the utility model nut, plays the role of rotation stop；The setting of disk 1, annular groove 7 and extension 5 plays increasing
Greatly with the effect of plastic part surface contact area, it is equivalent to gasket, it is therefore prevented that jack effect, so that the utility model
