Aiming at the situation, the utility model provides the sliding door of the refrigerator car in order to overcome the defects of the prior art.

In order to achieve the above object, the present utility model provides the following technical solutions: a sliding door of a refrigerator car,

The door comprises a carriage, a door lock, a door frame and a handle, and is characterized in that the carriage is provided with a sliding door, mounting plates are respectively arranged on the upper portion and the lower portion of the sliding door, the mounting plates are respectively fixedly connected with pulleys up and down, the pulleys are provided with six groups, the pulleys are respectively and slidably connected in sliding rails, the sliding rails are provided with two groups, and the sliding rails are respectively fixed in clamping grooves on the upper portion and the lower portion of the door frame.

Further, a limit groove is formed in the rear side of the carriage.

Further, the sliding door and the limiting groove are positioned on the same side of the carriage, and when the sliding door is opened, the sliding door can slide into the limiting groove.

Further, the sliding door is respectively fixed with the mounting plates through the screw rods and the nuts, and the mounting plates are provided with six groups.

Further, the sealing rubber strip is arranged on the inner side of the door frame, so that the sealing performance of the refrigerated vehicle is guaranteed.

Further, a handle is arranged on the sliding door, a door lock is arranged on the sliding door, and the door lock is provided with two groups which are respectively positioned above and below the handle.

Compared with the prior art, the sliding door of the refrigerator car provided by the utility model has the following beneficial effects: the sliding door slides into the limiting groove through the cooperation of the pulley and the sliding rail when the door is opened, so that the occupation of the external space is reduced, and the door can be opened even if the situation of parking congestion occurs. When avoiding staff to carry goods, produce visual angle blind area, take place the collision accident, the mode of push-and-pull door direct slip limiting groove, security when increasing the transport.
