Description

Technical Field

[0001] The utility model relates to the technical field of square pins, in particular to a square pin anti-theft structure for a folding box. Background Art

[0002] Square pins are a common mechanical connection element, which are usually made of metal. The main function of square pins is to firmly connect two or more parts together to prevent them from separating when subjected to force. In the design of folding boxes, square pins can be used to fix the various parts of the box to prevent the box from being deformed or damaged due to vibration or impact during transportation.

[0003] The traditional anti-theft structure requires welding of anti-theft bolts. Since it is installed after the box is painted, it cannot be completed entirely in the workshop. This method will not only damage the hot-dip galvanized layer of the square pin itself, but also damage the box paint affected by welding spatter. Both require subsequent repairs, and the repair effect cannot be well guaranteed. On-site welding in bad weather also poses certain safety hazards. At the same time, since the square pin is hot-dip galvanized as a whole after assembly and processing, the galvanized layer after hot-dip galvanizing will have a certain impact on the subsequently installed anti-theft bolts.
