Secondary locking system for lower side door of general open wagon
The invention discloses a general open wagon lower side door secondary locking system which comprises a lower side door plate, a lower side door hinge and a hasp assembly and further comprises a secondary anti-opening device, the secondary anti-opening device comprises a lock seat, a lock pin and lock iron, the lock seat is in bilateral symmetry, and a left side plate and a right side plate extend forwards to form a lock iron placement groove; a lifting lightening hole and a lock iron mounting hole are formed in the upper portion and the lower portion of the lock iron correspondingly, and the lock pin horizontally penetrates through the lock iron mounting hole and the left side plate and the right side plate of the lock seat so that the lock iron can be mounted in the lock iron mounting groove. The lock pin comprises a lock pin rotating shaft and a lock pin handle which is mounted at the left end of the lock pin rotating shaft and is in a vertical state initially. The lock pin rotating shaft comprises a large-diameter section 711 with the diameter larger than the hole diameter of the lock iron mounting hole and a small-diameter section with the diameter matched with the diameter of the lock iron mounting hole, planes are symmetrically arranged on the large-diameter section 711 in the vertical direction, the distance between the planes is smaller than the diameter of the small-diameter section, and limiting protrusions are symmetrically arranged on the inner side face of the lock iron mounting hole in the front-back direction. The unlocking device has the advantages of saving time and labor, reducing cost, providing unlocking double guarantees, being strict in unlocking condition, good in locking effect and the like.
本发明公开了一种通用敞车下侧门二次锁闭系统，包括下侧门门板、下侧门折页和搭扣组件，还包括二次防开装置，二次防开装置包括锁座、锁销和锁铁，锁座左右对称且左右侧板向前延伸形成锁铁安置槽，锁铁上下分别设有提拿减重孔和锁铁安装孔，锁销水平穿过锁铁安装孔及锁座左右侧板从而将锁铁安装在锁铁安置槽内，锁销包括锁销转轴和安装在锁销转轴左端初始呈竖直状态的锁销手柄，锁销转轴包括直径大于锁铁安装孔孔径的粗径段711和直径与锁铁安装孔适配的细径段，粗径段711上下对称设有平面且平面之间距离小于细径段直径，锁铁安装孔的内侧面前后对称设有限位凸起，具有省时省力、缩减成本、提供解锁双重保障、解锁条件严格、闭锁效果好等优点。
