Description
Technical field
The utility model relates to fastener areas more particularly to a kind of waterproof self-clinching nuts.
Background technique
Self-clinching nut is relatively common nut, and self-clinching nut is called riveting nut, self-fastening nut, be applied to thin plate or
A kind of nut on metal plate, shape is rounded, and one end is with embossing tooth and guide groove.Its principle is to be pressed into metal plate by embossing tooth
Preset hole location, it is however generally that the aperture of preset holes is slightly less than the embossing tooth of self-clinching nut, and the flower of self-clinching nut is made by pressure
Tooth, which is squeezed into plate, makes to cause the periphery in hole to generate plastic deformation, and deformations are squeezed into guide groove, to generate the effect of locking.
Can there is multiple guide groove in one nut, the same guide structure by nut front end is by sheet metal component lead-ingroove, because of metal plate
There is certain gap between part and slot, if this sheet metal component with self-clinching nut is for that will let out in the container of holding liquid
The case where leakage.
Utility model content
For above-mentioned technical problem of the existing technology, the utility model provides a kind of waterproof self-clinching nut, including
Section is limited, the limit section divides the first confined planes and the second confined planes again, and first confined planes side is thin plate fixing end, institute
Stating thin plate fixing end includes the first boot segment and indentation section, and second confined planes side is expansion end, and the expansion end includes
Extension mouth and the second boot segment；Entire nut other than limit section is regular hexagon, draw by the first boot segment, indentation section, second
Leading section is rotary body, and card slot is equipped between the second confined planes and the second boot segment, and from the first boot segment, is followed successively by the
One boot segment, indentation section, limit section, card slot and the second boot segment, and be structure as a whole；In second boot segment and slot
An extension mouth is installed, from the front of the extension mouth toward as viewed from the axis of nut, the extension mouth is an isoceles triangle
The space of shape, extension mouth pass through the axis of nut, extend radially through entire nut；First boot segment has one section close to the end face of nut
Taper face, taper face have a Duan Yuanzhu toward limit section side, cylindrical surface toward limit section side have one section it is recessed to nut axis direction
Arcwall face, arcwall face toward limit section side be indentation section, it is described indentation section circumference on be equipped in terms of nut radial direction
Lines wave-shaped is removed, the second boot segment is entirely in certain taper, and card slot is equipped between the second boot segment and limit section, described
Card slot is cylindrical body card slot, and the width of card slot is greater than the plate thickness being located in card slot, and the diameter of card slot cylindrical body is less than plate
Aperture；Extension mouth is in maximum gauge of the length of nut axis direction less than the second boot segment, two isosceles of the extension mouth
The angle on side is overlapped with the end face of nut；The maximum gauge of first boot segment is cylinder, the body diameter of first boot segment
Less than indentation section diameter；It is pressed into section diameter and is less than limit section diameter；Diameter of second boot segment close to card slot one end is greater than card slot
Diameter.
Preferably, the long bottom side length for being greater than triangle of the waist of the extension mouth triangle.
Preferably, half of the extension mouth in the maximum gauge that the length of nut axis direction is the second boot segment.
A kind of waterproof self-clinching nut of the utility model at least has the advantage that
(1) the indentation section mentioned in the utility model is exactly to be embossed tooth, is pressed into the aerial of sheet metal component by will be pressed into section, real
The fixation of sheet metal component and self-clinching nut is showed；Another sheet metal component with holes is introduced into card slot by the second boot segment, at this point, metal plate
There are certain gaps between golden part and card slot, by the way that expansion end is arranged in the nut to press, specifically: drawing described second
It leads section and groove position and is equipped with an extension mouth, from the front of the extension mouth toward as viewed from the axis of nut, the extension mouth
For the space of an isosceles triangle, extension mouth passes through the axis of nut, extends radially through entire nut；Extension mouth is in nut axis side
To maximum gauge of the length less than the second boot segment, the end face weight of the angles of the waist edges such as two of the extension mouth and nut
It closes, that is to say, that the extension mouth positioned at nut one end is a notch of nut.Not common rectangular of the shape of this notch
Shape, but triangle.By the extension mouth of this triangle, after screw is screwed into nut, card slot and the second boot segment can be outside
Expansion reduces the gap between stamping holes and card slot, it is therefore prevented that gap of the liquid between stamping holes and card slot is flowed through, and is played
The effect of waterproof.
(2) it in order to further increase the effect of waterproof, is found by a large amount of actual tests, the extension mouth triangle
When waist length is greater than the bottom side length of triangle, the effect of expansion is more preferable.And when extension mouth (131) are in the length of nut (1) axis direction
Degree be the second boot segment (132) maximum gauge half when, expansion effect is best, and will not stress concentration lead to nut quilt
It destroys.
