Abstract

The invention discloses a large-opening-degree sliding plug door system, belongs to the technical field of rail transit vehicle door systems, and solves the problem of insufficient opening degree due to the fact that a door leaf has a large opening degree. The plugging and pulling movement is realized through a right-angle plugging and pulling mode; a plurality of groups of bearing trolleys are arranged, move in the track and transmit the movement of the rack to the translation rod assembly; the upper ends and the lower ends of the translation rod assemblies drive the door leaves to move while moving in the upper sliding rail and the lower sliding rail respectively. Manual unlocking can be carried out by utilizing the driving lever assembly; the lifting hinge increases the degree of freedom of the upper guide rail, ensures that rollers on the left side and the right side of the movable roller assembly always make contact with the lower portion of the upper guide rail in the door leaf movement process, ensures balanced stress between a bearing rail profile and a bearing trolley, and ensures the movement reliability; the mechanical device adopts an over-dead-point locking mode, and a buffer head is arranged at the front end of the upper guide rail, so that the door leaf is safely and reliably locked.

Description

technical field [0001] The invention belongs to the technical field of rail transit vehicle door systems, in particular to a large-opening plug sliding door system. Background technique [0002] The sliding door is a rail transit vehicle door, which has two actions of plug and pull. [0003] When the sliding door is closed, it is inserted into the car door from the inside or outside of the car to make it closed and sealed; when the door is opened, when the door is moved away from the door a certain distance, it can slide inside or outside the car body. [0004] The opening degree of the existing vehicle door system is generally small, which cannot meet the loading and unloading requirements of large boxes or articles. SUMMARY OF THE INVENTION [0005] Purpose of the Invention: The purpose of the present invention is to provide a large-opening plug sliding door system to solve the problem of insufficient opening. [0006] Technical scheme: in order to realize the above-me...
