According to the opening device, a door opening and closing handle is arranged without additional door opening and closing tools, thereby being convenient to operate; and the opening device has a two-stage locking function according to different door gaps needed in transportation, can meet the usage demand of different working conditions, the usage reliability of the opening device for the side door can be improved, and the transportation economic benefits can be increased.

Description

technical field [0001] The invention relates to a side door of a railway freight car body, in particular to an opening device for a side door of a railway freight car. Background technique [0002] At present, the traditional way of fixing the side door of railway freight cars in my country is to overlap the door hinge and the door hasp. During use, the side door panels lock the hinges through the left and right buckles, and the left and right buckles must be opened or locked to open and close the side door panels. But there are following defects in existing railway wagon side door opener: [0003] First, when the truck is transporting goods, the side door panel is squeezed by the goods inside the truck, and the friction between the door hinge and the door buckle increases, making it difficult to open and close the door, and additional knocking is required to open and close the door tool, causing inconvenience to the flip door to open. [0004] Second, when the truck tran...

Problems solved by technology

[0003] First, when the truck is transporting goods, the side door panel is squeezed by the goods inside the truck, and the friction between the door hinge and the door buckle increases, making it difficult to open and close the door, and additional knocking is required to open and close the door tool, causing inconvenience to the flip door to open

[0004] Second, when the truck transports bulk goods, in order to effectively fix the bulk cargo, some fixing parts such as rope bolts on the vehicle chassis need to be used on the truck. However, in order to ensure a good sealing effect, the truck does not reserve any space in the truck at present. Therefore, the friction between the fixed part and the side door panel will be increased, and the opening device of the side door of the railway wagon will be damaged over time.
