Description

technical field [0001] The invention relates to a door lock device for a railway freight gondola car, in particular to a lower side door lock for a railway freight gondola car. Background technique [0002] Railway freight gondola cars are mainly used to transport coal, ore, building materials, machinery and equipment, steel and timber. The vast majority of railway freight open cars in my country are equipped with flip-up lower side doors. The locking device mainly adopts buckle seat and buckle iron assembly. In the seat, and then rotate the buckle iron into the slot of the buckle seat, so that it can be pressed against the hinge to achieve the purpose of locking. Because the buckle iron is easy to jump out from the buckle seat, it not only fails to achieve the purpose of locking, but also buries a huge potential safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a firm, reliable and safe door lock on the lower side of a r...
