Railway freight car locking mechanism

Abstract

The invention discloses a railway freight car locking mechanism which comprises locking structures and sealing structures which are installed on a sliding door A and a sliding door B. Linkage plug pins are installed in the sliding door A and the sliding door B; the locking structures are connected with the sealing structures through sealing transmission structures; the locking structures comprise the active locking structure installed on the sliding door A and the passive locking structure installed on the sliding door B; the active locking structure drives the passive locking structure to achieve locking of a freight car door on a freight car; and when the locking structures move, the sealing transmission structures in the sliding door A and the sliding door B are linked, so that the sliding door A and the sliding door B are sealed with the edge of a freight car door hole. The novel structure provided by the invention is used for being mounted on the freight car carriage door of the railway freight car, and fastening of locking is realized by designing a communicated structure; and meanwhile, a telescopic rubber sealing gasket is utilized, so that the whole freight car has certain air tightness, sliding is not affected, and the situation that air flows into the freight car carriage from a door slot is avoided.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a railway freight car locking mechanism. Background technique [0002] Rail transportation is a form of transportation that uses railway trains to transport passengers and goods. It plays an important role in the social material production process. It is characterized by large transportation volume, fast speed, low cost, and generally not restricted by climatic conditions, so it is suitable for long-distance transportation of bulk and heavy goods. [0003] Among them, the doors of railway freight cars are generally very poorly sealed, and the current railway freight cars are used to transport some animals. Contents of the invention [0004] The purpose of the present invention is to provide a railway freight car locking mechanism to solve the problems raised in the above background art. [0005] To achieve the above object, the present invention provides the following technical solut...

AI Technical Summary

Problems solved by technology

[0003] Among them, the doors of freight cars transported by railways are generally very poorly sealed, and the current railway freight cars are used to transport some animals. If there is no airtightness, it will cause cross-wind, which will reduce the temperature inside the car, which is not conducive to the transportation of living animals.
