Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 bolt head, 2 bolt pole portions, 3 backing plates, 4 anti-skidding lines, 5 bulges, 6 grooves, 7 transverse through holes and 8 notches.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, an automobile fastener bolt, including bolt head 1 and bolt pole portion 2, one side that bolt pole portion is close to the bolt head still is provided with anti-loosening structure, anti-loosening structure includes backing plate 3, the backing plate is round platform shape, and the great terminal surface of backing plate is terminal surface down, and keeps away from bolt head one side, and the terminal surface is provided with anti-skidding line 4 under the backing plate, the backing plate middle part is provided with the logical groove that runs through from top to bottom, lead to the inslot and be provided with the screw thread with bolt pole portion looks adaptation. The backing plate can realize fixedly with bolt shank looks spiro union, and when bolt erection joint was in the car, the antiskid line can play the effect that prevents bolt rotation on the backing plate, and then realizes preventing not hard up of bolt, guarantees the stability of bolt-up.
Further, the upper end face of the base plate is provided with a protruding portion 5, the protruding portion is annular, an inner concave portion for embedding the protruding portion is formed in the lower end face of the bolt head, an elastic cushion is arranged on the inner side wall of the inner concave portion, and the protruding portion is coated by the elastic cushion. The rotation of the backing plate is further prevented by means of the clamping of the elastic pad. Or, further, a cylindrical plate (not shown in the figure) is additionally arranged on the upper end face of the backing plate, the cylindrical plate also penetrates through the rod part of the bolt, a protruding part and an inner concave part are respectively arranged on the upper part and the lower part of the cylindrical plate, and the cylindrical plate is embedded in the head part of the bolt, so that the thickness of the backing plate is changed, and the application range is widened.
Further, recess 6 has been seted up at bolt head middle part, the recess gos deep into bolt pole portion, set up the horizontal through-hole 7 of two symmetries between recess and the bolt pole portion lateral wall, be provided with the limiting plate in the through-hole, limiting plate one end is provided with friction line, and the other end is provided with the bolster, the recess interpolation is equipped with the locating lever, the locating lever supports the bolster of limiting plate, and the friction line of limiting plate supports the logical groove of backing plate. Utilize the further spacing backing plate of limiting plate, guarantee the stability of being connected between backing plate and the bolt, and then realize the stability when whole is applied to the car fastening.
