The content of the invention
The technical problems to be solved by the invention are to provide a kind of new automobile grounding nut, to overcome above-mentioned existing skill Deficiency in art.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of new automobile grounding nut, grounding nut Including nut and for connecting the conducting strip of ground wire, conducting strip is arranged on nut, and conducting strip can enter around the axis of nut Row is rotated.
The beneficial effects of the invention are as follows:It can save and once unclamp grounding nut release action, save and beat is installed, it is to avoid The generation of security incident.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, conducting strip is rotationally enclosed on nut.
Further, the outer wall of nut is provided with circular ring slot, and conducting strip is rotationally nested on nut set circular rings In groove.
Further, conducting strip is annular in shape.
Further, the thread of the internal thread hole of nut shells length of the paint bath along internal thread hole certainly provided with multiple from stripping paint bath Direction is spent to set, it is each to run through whole internal thread hole from stripping paint bath.
Further, it is 0.5mm-3mm from the width of stripping paint bath;Length from stripping paint bath is 1mm-4mm.
Further, it is 1mm-2mm from the width of stripping paint bath;Length from stripping paint bath is 2mm-3mm.
Further, it is one to six from the quantity of stripping paint bath.
Further, it is three or four from the quantity of stripping paint bath.
Further, all paint baths of stripping certainly set on the thread of internal thread hole are angularly distributed.
It is using above-mentioned further beneficial effect:It is attached when on the stud that grounding nut is installed to after electrophoresis Can voluntarily peel off in the electrophoretic paint on stud with the urgent of nut, and by from stripping paint bath discharge, conductive work(can be completed Can, projection welding process can be used in stud and metal plate welding scheme, while using may be such that ratio of defects is only 100,000 after this grounding nut / mono-, welding quality is more stablized.
