Push-pull turnover locking device
The invention discloses a push-pull turnover locking device, which is used for locking a door of a railway freight car and consists of a lock pin chute seat, a fixed lock seat, a lock pin and a turnover stopper, the lock pin sliding groove seat is welded and fixed to a vehicle door and comprises a sliding groove with a lower opening, and a step is arranged on the front side face of the bottom end. The fixed lock seat is fixed on a vehicle body and comprises a rectangular through hole; the lock pin is in sliding fit with a sliding groove of the lock pin sliding groove seat, can slide up and down along the sliding groove and comprises a boss of a top end step structure and a lock tongue at the lower end, and the lock tongue is located in a through hole of the fixed lock seat in a downward moving locking state. The turnover stopper is composed of a push rod, a support, a pin shaft and a clamp spring. According to the locking device, a door slot gap between the door plate and the side wall plate is reduced or eliminated, and granular goods are prevented from being lost and scattered; the turnover stop assembly can effectively prevent the lock pin from being separated from the lock groove seat, the lower side door is accidentally opened, and the performance is reliable; the locking device is fixed on the hinge of the lower side door and has pressing force on the hinge, and the lower side door is still effectively locked through the lock pin even if the hinge deforms.
本发明公开了一种推拉翻转锁闭装置，用于铁路货车车门的锁闭，由锁销滑槽座、固定锁座、锁销、翻转止档构成；锁销滑槽座焊接固定于车门上，包括下方开口的滑槽，底端前侧面设置台阶；固定锁座固定于车体上，包括一长方形通孔；锁销与锁销滑槽座滑槽滑动匹配，可沿滑槽上下滑动，包括顶端台阶结构的凸台和下端的锁舌，下移锁闭状态锁舌位于固定锁座通孔中；翻转止档由推杆、支座、销轴、卡簧构成。本发明锁闭装置减小或消除门板与侧墙板之间的门缝间隙，预防颗粒状货物遗失和洒落；翻转止档组成可有效防止锁销脱离锁槽座，下侧门意外开启，性能可靠；锁闭装置固定在下侧门折页上，对折页具有压紧力，即使折页变形后仍然通过锁销有效锁紧下侧门。
