Problems solved by technology

[0002] At present, nut products with self-locking function are everywhere, but screw products with self-locking function are not visible. Therefore, when only screws are used to tighten the workpiece, it is difficult to effectively prevent the connection from loosening. In order to effectively prevent the connection from loosening, some auxiliary measures must be adopted, and the structure is complex.

Abstract

The invention discloses a self-locking screw. The self-locking screw comprises a screw rod and a screw head, wherein the screw rod and the screw head are connected, and external threads are formed in the excircle of the screw rod. The self-locking screw is characterized in that an annular groove is formed in the root portion, connected with the screw head, of the screw rod, the annular groove is filled with plastic materials, the filled plastic materials form a cylinder excircle, the diameter of the cylinder excircle is equal to the outer diameter of the threads of the screw rod, a plurality of axial notch grooves are formed in the surface circumference of the cylinder excircle, a special-shaped counterbore is formed in the bottom end face, connected with the annular groove, of the screw head, and the special-shaped counterbore is filled up with the plastic materials. The self-locking screw has the self-locking function, effectively prevents connection from loosening, and is simple in structure.

Description

technical field [0001] The invention relates to a fastener product, in particular to a self-locking screw. Background technique [0002] At present, nut products with self-locking function are everywhere, but screw products with self-locking function are not visible. Therefore, when only screws are used to tighten the workpiece, it is difficult to effectively prevent the connection from loosening. In order to effectively prevent the connection from loosening, some auxiliary measures must be adopted, and the structure is complex. Contents of the invention [0003] In view of the problems existing in the current known technology, the technical problem to be solved by the present invention is to provide a self-locking screw with a self-locking function, which can effectively prevent the connection from loosening and has a simple structure. [0004] The present invention is implemented through the following technical solutions: [0005] The self-locking screw includes a conn...
