The mandrel and the reinforcing rib plate are integrally stretched and formed, and a thread is provided in the positioning through hole at the center of the mandrel, so as to facilitate the connection of the lock bolt as a whole with the safety lock structure through bolts and the positioning through hole.

[0008] Preferably, the cover plate is integrally formed with a cover body embedded in the bolt body, and the cover body is provided with a plurality of slots corresponding to the reinforcing ribs on the bolt body. The cover body on the inner side of the cover plate can be embedded in the bolt body by interference fit, and during the pressing process, the slots on the cover body and the reinforcing ribs will be inserted into each other, thus completing the assembly of the bolt body and the cover plate.

[0009] Preferably, a matching column is integrally formed in the middle of the inner side of the cover plate, a matching hole is opened in the center of the matching column, and the matching column can extend into the positioning through hole of the core shaft. The matching column on the inner side of the cover plate can extend into the positioning through hole for alignment and fixation.

[0010] Preferably, the side wall of the mating column is provided with a plurality of outward expansion grooves. The outward expansion grooves provided on the side wall of the mating column can facilitate deformation of the mating column and press the mating column into the positioning through hole.

[0011] Preferably, the matching column and the positioning through hole are interference fit. Before use, the cover plate is placed on the bolt body, and the matching column on the inner side of the cover plate is pressed into the positioning through hole in the bolt body through interference fit, so that the bolt body and the cover plate can be quickly assembled.

[0012] Preferably, the cover plate surface is integrally formed with convex points. The convex points on the cover plate surface are integrally injection molded, and whether to injection mold the convex points can be selected according to demand. The convex points can enhance the strength of the cover plate and prevent collision.

[0013] Therefore, a split safe lock bolt structure of the present invention has the following advantages: it can be mass-produced and quickly produced, the split lock bolt can be quickly assembled, and fixation and assembly can be completed without additional fasteners, which can effectively reduce the difficulty of production and ensure product accuracy and quality.
