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 and 2: a self-locking high-strength bolt structure comprises a screw rod 1 with a groove, a spring washer head, a hoop 2, a washer 5 and a nut 6; one side of the screw rod with the groove is provided with a groove, the spring gasket head is arranged in the groove, the hoop is sleeved at the groove of the outer ring of the screw rod with the groove, the spring gasket head is limited in the groove, and the other side of the screw rod with the groove is sleeved with the gasket and fixed through the nut.
Further, the spring washer head comprises a wedge-shaped spring washer head 3 and a rectangular spring washer head 4; one side in the groove opening of the screw rod with the groove is wedge-shaped, the other side is rectangular, the wedge-shaped spring washer head and the rectangular spring washer head are arranged in the groove opening side by side, wherein one side of the wedge-shaped spring washer head is wedge-shaped, the other side of the wedge-shaped spring washer head is rectangular, one side of the rectangular shape of the wedge-shaped spring washer head and the inner side of the wedge-shaped of the groove opening are mutually buckled, and one side of the wedge-shaped spring washer head and the rectangular spring washer head are mutually buckled; the hoop limits the wedge spring washer head and the square spring washer head within the slot.
The grooved screw is provided with a groove at one end of the screw, and one side of the groove opening is designed into a wedge shape and used for positioning the wedge-shaped spring washer head in place according to the center. The screw rod with the groove hides the wedge-shaped spring washer head and the rectangular spring washer head before the bolt is installed, and after the bolt is installed, the screw rod with the groove and the wedge-shaped spring washer head form a buckle to provide a counter-force support for pretensioning force of the bolt.
One side of the wedge-shaped spring washer head is designed to be wedge-shaped and used for positioning the straight-square spring washer head according to the center. After the bolt is installed, the wedge-shaped spring washer head forms a buckle with the screw groove to prevent the bolt from being pulled out. The wedge-shaped spring washer head is limited in the screw groove by the hoop before installation, and when the hoop is ejected out during installation, the wedge-shaped spring washer head automatically ejects out to form a buckle.
