A railway freight car locking mechanism

Abstract

The invention discloses a locking mechanism for railway wagons, which includes a locking structure and a closing structure installed on sliding doors A and B. Both sliding doors A and B are equipped with interlocking latches, and the locking structure The sealing structure is connected with the sealing structure through the sealing transmission structure. The locking structure includes 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 realize the truck For the locking of the truck door, the locking structure moves while the sealing transmission structure in the sliding door A and the sliding door B is linked so that the sealing of the sliding door A, the sliding door B and the edge of the truck door hole is closed. The new structure proposed by the present invention is used to be installed on the carriages of railway freight cars, and the fastening of the lock is realized by designing a connected structure; at the same time, the stretchable rubber gasket is used to make the whole have a certain airtightness, and at the same time It will affect the sliding, so as to avoid the cross-wind from the door seam to the interior of the truck compartment.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a locking mechanism for a railway freight car. Background technique [0002] Railway transportation is a mode of transportation that uses railway trains to transport passengers and goods. It plays an important role in the process of social material production. It is characterized by large transportation volume, fast speed, low cost, and is generally not restricted by climatic conditions, so it is suitable for long-distance transportation of bulky and heavy goods. [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 in the compartment, which is not conducive to the transportation of living animals. Contents of the invention [0004] The object of the present invention is to p...

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.
