During transport, because other reasons such as vibration can be released voluntarily, the normal use to computer brings harmful effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of contact that can effectively increase between plastic part
Area, realization are reliably connected with screw, prevent the high intensity anti-return nut voluntarily released.
Technical solution of the present utility model is to provide a kind of high intensity anti-return nut with following structure, including
Barrel nut body, nut body are provided with tapped through hole, wherein, the outer wall top of nut body is provided with first annular bullet
Piece, the outer wall bottom of nut body are provided with the second annular shell fragment, and the diameter of first annular shell fragment is the 2.5 of nut body diameter
Times, the second annular shell fragment is equal with the diameter of first annular shell fragment, and the thickness of the second annular shell fragment and first annular shell fragment is
1mm, the periphery of first annular shell fragment are provided with some first U-shaped gap and the first axial catch, the first axial catch and the first ring
The perpendicular of shape shell fragment, the periphery of the second annular shell fragment are provided with some second U-shaped gap and the second axial catch, the second axle
To catch and the perpendicular of the second annular shell fragment.
High intensity anti-return nut described in the utility model, wherein, the first U-shaped gap interlocks with the first axial catch
Distribution, the second U-shaped gap are interspersed with the second axial catch.
High intensity anti-return nut described in the utility model, wherein, if there is even circumferential on the outer wall of the nut body
Dry strip bulge, strip bulge is between first annular shell fragment and the second annular shell fragment.
High intensity anti-return nut described in the utility model, wherein, the cross section of the strip bulge is trapezoidal.
High intensity anti-return nut described in the utility model, wherein, the is provided between first annular shell fragment and nut body
One triangle stiffener, the second triangle stiffener is provided between the second annular shell fragment and nut body.
After above structure, compared with prior art, the utility model high intensity anti-return nut has advantages below：
After in the part of the utility model insertion plastic material, the plastics of fusing can be wrapped in the periphery of nut body, solidification to be cooled
Afterwards, first, second annular shell fragment just considerably increases the contact area with plastic part, improves the compactness of both connections；
When by slightly larger torsion or shearing force, U-shaped gap and axial catch can prevent the rotation of the utility model nut, play
Rotation stop effect；Under the collective effect of U-shaped gap and axial catch, the meeting that embedded nut is connected with plastic part is more firm
Lean on, reach good anti-loose effect.
U-shaped gap and being staggered for axial catch can make anti-rotation and anti-loose effect more preferable.
Some strip bulges of circumference uniform distribution can further improve anti-rotation of the present utility model and anti-loose effect.
The trapezoidal strip bulge in cross section can make anti-rotation effect more preferable.
First, second triangle stiffener can further improve the company between first, second annular shell fragment and nut body
Connect intensity.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model high intensity anti-return nut.
Embodiment
The utility model high intensity anti-return nut is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, in this embodiment, the utility model high intensity anti-return nut includes barrel nut sheet
Body 8, nut body 8 are provided with tapped through hole 3.The outer wall top of nut body 8 is provided with first annular shell fragment 1, nut body 8
Outer wall bottom is provided with the second annular shell fragment 10, and the diameter of first annular shell fragment 1 is 2.5 times of the diameter of nut body 8, the second annular
Shell fragment 10 is equal with the diameter of first annular shell fragment 1, and the thickness of the second annular shell fragment 10 and first annular shell fragment 1 is 1mm.The
The periphery of one annular shell fragment 1 is provided with some first U-shaped gap, 4 and first axial catch 2, the first axial catch 2 with it is first annular
The perpendicular of shell fragment 1, the periphery of the second annular shell fragment 10 are provided with some second U-shaped gap, 9 and second axial catch 11, the
The perpendicular of two axial 11 and second annular shell fragments 10 of catch.
First U-shaped gap 4 is interspersed with the first axial catch 2, and the second U-shaped gap 9 interlocks with the second axial catch 11
Distribution.U-shaped gap and being staggered for axial catch can make anti-rotation of the present utility model and anti-loose effect more preferable.
Even circumferential has some strip bulges 7 on the outer wall of nut body 8, and the cross section of strip bulge 7 is trapezoidal, bar shaped
Between first annular 1 and second annular shell fragment 10 of shell fragment, some strip bulges of circumference uniform distribution further increase projection 7
Anti-rotation of the present utility model and anti-loose effect.
