Rail car side door lock and rail car door

Abstract

The invention discloses a rail car side door lock and a rail car door. The rail car side door lock comprises an inner operating device, an outer operating device and a ball-head tension rod assembly.The inner operating device comprises an inner operating handle, an inner locking box assembly, an inner unlocking shifting block, a safety block and a locking bottom plate. The outer operating devicecomprises an outer operating handle, an outer locking plate assembly, a locking bottom plate and an outer unlocking shifting block. The ball-head tension rod assembly comprises an unlocking sliding block, a ball-head tension rod, a lock tongue reset pressure spring, a lock tongue sleeve and a lock tongue. The inner unlocking shifting block and the outer unlocking shifting block both comprise shifting block shafts and shifting block bodies, wherein the shifting block shafts and the shifting block bodies are mutually connected. The shifting block shaft of the inner unlocking shifting block is connected with the inner operating handle, and the shifting block shaft of the outer unlocking shifting block is connected with the outer operating handle. When unlocking is needed, the inner operatinghandle or the outer operating handle drives the unlocking sliding block to downwards move, the unlocking sliding block pulls the lock tongue to be contracted into the lock tongue sleeve to complete unlocking, and when the rail car side door is opened from the inner side, locking of the safety block further needs to be released. The rail car side door lock and the rail car door are simple in structure, convenient to mount and maintain, and high in overall reliability.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a rail car side door lock and a rail car door. Background technique [0002] At present, the locking mechanism of the side door of the train driver's cab is mostly a lever lock. Because there are many links between the lever and the unlocking component, the assembly operation is complicated. At the same time, the skill requirements of the assembly workers are relatively high, so the overall reliability of the door lock is not high. Especially after-sales customer service personnel cannot control the maintenance and maintenance quality of the door lock, which increases the difficulty of the maintenance and maintenance of the door lock and reduces the maintenance reliability of the locking mechanism. [0003] Therefore, reducing the assembly and maintenance requirements of door locks and improving the reliability and maintainability of the device has become a practical deman...
