The technological scheme that the utility model provides is: a kind of attaching nut who is used for electric box, comprise that nut and coats nut so that nut embeds the tubular nut seat of electric box clamping seam, it is characterized in that the radially both sides of this nut respectively are shaped on a card handle that stretches to the outer diameter; The bottom central authorities of described nut seat are shaped on one and are beneficial to the through hole that bolt passes through, and the chute that the circumferential wall section of nut seat is not shaped on a front and back symmetric arrangement passes through outward for the card handle of nut and stretches out; Be shaped on the circle flanging of turnover to the outer diameter around the top of nut seat.
Described chute extends to the nut seat bottom from the flanging position on nut seat top, to realize the slip of nut along the nut seat axial direction.
The position, the left and right sides of the circumferential wall portion of described nut seat is shaped on a projection of arranging and being connected with described flanging symmetrically respectively, to limit the circumferential degrees of freedom of nut seat after in the electric box clamping is stitched.
Described nut seat is formed by a monoblock spring steel plate punching out; The two ends head of this spring steel plate are drawn close after by the punching out bending mutually, and the butt joint of formation communicates with the chute on nut seat top.
The bottom end face of described nut is concordant with the bottom surface of two card handles, and the top end face of nut protrudes in the end face of two card handles.
The beneficial effects of the utility model are: because the card handle of the nut in the utility model has enough length, after embedding electric box clamping seam, the thin plate edges of boards of clamping seam both sides are blocked position that the handle card pricks big (referring to Fig. 6), thereby the attaching nut not only is difficult to pull from the clamping seam, and (bigger distortion is only taking place in the thin plate edges of boards, the situation that the attaching nut pulls from the clamping seam just might take place when promptly producing destructive plastic deformation), and can stitch the bigger support force (support pulling force) of thin plate edges of boards acquisition of both sides from clamping, make that being connected and fixed of accessory is more solid and reliable.In addition, the utility model is also very convenient with being connected of electric box clamping seam: only need earlier two card handles of nut to be aimed at the clamping seam and made it fall into the clamping seam by the attaching nut down, the rear portion that nut 90 degree that are rotationally connected then make two card handles of nut turn to clamping seam both sides thin plate edges of boards gets final product; Projection on the described nut seat can stop two of nut to block being rotated further of handles, thus the reliable location of guaranteeing the attaching nut.This structure not only makes operator's work become convenient more, has also significantly improved installment work efficient.
