Abstract

The invention discloses an observation door for a wagon. The observation door comprises a door frame, an upper door plate and a lower door plate; the door frame comprises a pair of vertically parallelside frame guide rails, and a doorsill connected with the lower parts of the pair of side frame guide rails; and the upper door plate is arranged on the upper part in the door frame, the lower door plate is arranged on the lower part of the upper door plate in the door frame, and the lower door plate can slide up and down along the side frame guide rails. Through side frame guide rail structuresof the door frame, the lower door plate can slide up and down along the side frame guide rails, and thus an operator outside the wagon conveniently observes the internal condition of a wagon body andfinds problems in time.

Description

technical field [0001] The invention belongs to the technical field of locomotive manufacturing, and in particular relates to an observation door for railway freight cars. Background technique [0002] At present, the side doors assembled outside the body of existing trucks in China include: large-sized doors are mainly used for loading and unloading goods, and small-sized doors are mainly used for special additional functions such as observing the internal conditions of the car body and ventilation. The main structural type of large-sized doors is to turn up around a fixed point and open outwards as a whole; due to the small overall size, small-sized doors are generally designed as a pull-out type or an outward-turning type. From the current point of view, the outward-turning type is more widely used. However, small-sized doors are mainly used to realize some simple and special additional functions such as observation and ventilation. If they are realized by flipping struct...
